- [00:00:00.000]All right, good morning.
- [00:00:03.020]Welcome to the August edition
- [00:00:04.770]of the second Tuesday at nine.
- [00:00:06.720]I'm Eric Hunt from University
- [00:00:08.080]of Nebraska Extension. Nine o'clock
- [00:00:09.660]central, eight o'clock mountain
- [00:00:11.060]time. Thank you for listening
- [00:00:12.490]in this morning.
- [00:00:14.420]Started off with, we have a
- [00:00:16.030]special field day coming up in
- [00:00:17.780]Fillmore County on August 25th.
- [00:00:20.120]I'm hoping to actually attend
- [00:00:21.270]at least some of this in person.
- [00:00:22.560]Jordan Aldrich will be talking
- [00:00:24.800]about soil health and cover
- [00:00:26.660]crops and some other ways of
- [00:00:28.720]managing weeds.
- [00:00:29.940]And my understanding is there's
- [00:00:31.740]going to be a prime rib lunch
- [00:00:33.250]at Charlie's Pub afterward. Let
- [00:00:35.310]me get rid of this.
- [00:00:36.540]Okay, so just in terms of, this
- [00:00:44.120]was,
- [00:00:44.420]actually, I'm sorry, this was
- [00:00:45.750]from a while back. Here's the
- [00:00:48.060]most recent 30-day departure
- [00:00:49.850]precipitation.
- [00:00:50.820]So it has been very, very wet
- [00:00:52.260]here across a lot of the
- [00:00:53.400]northern plains and
- [00:00:54.820]particularly here across a lot
- [00:00:55.840]of the western Corn Belt.
- [00:00:57.140]And with the exception of just
- [00:00:58.680]parts of southwest Iowa, most
- [00:01:00.430]of Iowa's has been extremely
- [00:01:02.190]wet here in the last four to
- [00:01:04.210]six weeks.
- [00:01:05.120]It also extends into good
- [00:01:06.210]portions of eastern Nebraska. A
- [00:01:07.770]couple of areas in here maybe
- [00:01:09.360]have been sneaky dry.
- [00:01:10.400]But, you know, again, we had
- [00:01:11.550]some pretty significant
- [00:01:12.530]precipitation in some of these
- [00:01:13.670]areas back in,
- [00:01:14.420]late June. So we're not
- [00:01:16.010]necessarily like in significant
- [00:01:17.540]drought conditions here.
- [00:01:18.680]At least not this time.
- [00:01:20.580]We have been a little bit dry
- [00:01:21.990]here across portions of the
- [00:01:23.340]Sandhills. Panhandle a bit more
- [00:01:24.920]mixed.
- [00:01:25.400]Again, I would take a little
- [00:01:26.640]bit of these precipitation surpluses
- [00:01:28.280]with a little grain of salt.
- [00:01:29.660]Again, we do have,
- [00:01:30.840]there are known issues with,
- [00:01:32.330]particularly with radar
- [00:01:33.580]estimated precipitation
- [00:01:34.920]in the front range and the very
- [00:01:36.600]western part of the high plains.
- [00:01:38.600]So some of this is probably a
- [00:01:39.520]little bit overdone.
- [00:01:40.340]But suffice to say, it's been a
- [00:01:42.010]much better summer across the
- [00:01:43.290]Panhandle than it was last year.
- [00:01:44.420]at this time.
- [00:01:45.580]Looking at soil moisture percentiles.
- [00:01:49.160]So again, most of the state of
- [00:01:51.090]Nebraska is quite wet.
- [00:01:52.520]Now again, I think the, this
- [00:01:54.480]was from about a week ago. Iowa
- [00:01:56.110]had been a little bit drier the
- [00:01:57.430]previous week.
- [00:01:58.240]So I'd anticipate this actually
- [00:01:59.800]looking a lot more blue after
- [00:02:01.180]the recent precipitation.
- [00:02:02.740]Same story here in Wisconsin.
- [00:02:04.580]We had tremendous flooding over
- [00:02:06.750]the weekend in parts of southeastern
- [00:02:09.030]Wisconsin, particularly right
- [00:02:10.130]around Milwaukee.
- [00:02:11.640]Maybe a little bit drier across
- [00:02:12.940]the very eastern side of the
- [00:02:14.080]Corn Belt. But for the most
- [00:02:15.200]part, though,
- [00:02:15.760]most of the region is not
- [00:02:18.200]dealing with any major drought
- [00:02:19.800]stress.
- [00:02:20.400]There are pockets of south
- [00:02:22.170]central Nebraska are a bit, are
- [00:02:25.110]still doing a drought. But I
- [00:02:26.380]think in terms of the recent,
- [00:02:27.970]you know, precipitation, they
- [00:02:28.920]have at least a little bit of
- [00:02:30.600]topsoil moisture to work with.
- [00:02:32.000]Drought monitor. So the last
- [00:02:35.080]time I did a webinar, the
- [00:02:36.240]drought monitor showed quite a
- [00:02:37.690]bit of abnormal dryness and
- [00:02:38.780]some drought here across the
- [00:02:40.140]central and western Corn Belt.
- [00:02:41.880]Nebraska at that time was still
- [00:02:43.350]a bit of an epicenter of
- [00:02:44.640]drought for the central U. S.
- [00:02:46.450]And we have seen tremendous
- [00:02:48.010]improvement across the state.
- [00:02:50.080]There are pork portions of the
- [00:02:51.580]panhandle and portions of south
- [00:02:53.200]central Nebraska that have not
- [00:02:54.760]really had much improvement in
- [00:02:56.320]the last two months. But for
- [00:02:57.810]the most part, though, we have
- [00:02:59.440]seen tremendous improvement
- [00:03:00.940]here across this region.
- [00:03:02.680]Iowa basically right now is
- [00:03:03.740]free and clear of everything.
- [00:03:05.040]We've seen improvement in
- [00:03:06.510]Illinois. We've seen
- [00:03:07.300]improvements in Indiana. And I
- [00:03:08.600]would probably just say that
- [00:03:10.290]the fact that it was relatively
- [00:03:12.120]dry going into the early middle
- [00:03:13.950]portion of summer was probably
- [00:03:15.800]the only thing maybe preventing
- [00:03:17.700]some of the Midwest dealing
- [00:03:19.330]with significant flooding
- [00:03:20.990]problems this summer.
- [00:03:22.680]Versus we've had just like I
- [00:03:23.840]showed you earlier, we've had
- [00:03:25.130]just tremendous precipitation
- [00:03:26.490]here across portions of northeastern
- [00:03:28.090]Nebraska and certainly getting
- [00:03:29.430]into Iowa. So I think some of
- [00:03:31.140]the reasons that we are really
- [00:03:32.670]bullish on yields this year is
- [00:03:34.330]that we were a bit dry to start
- [00:03:35.870]the year. I think if we had
- [00:03:37.380]been super wet all year going
- [00:03:38.770]into the summer, we would be
- [00:03:40.060]dealing with a lot more issues.
- [00:03:41.720]Areas I've seen the biggest
- [00:03:43.250]improvements here would be kind
- [00:03:45.070]of just north of Albion, Elgin
- [00:03:46.800]area where we've had basically
- [00:03:48.550]a four category improvement in
- [00:03:50.380]two months.
- [00:03:51.840]So again, hydrologic whiplash
- [00:03:53.320]is definitely a thing. We
- [00:03:54.610]definitely have seen that so
- [00:03:55.920]far this summer.
- [00:03:56.920]In terms of rangeland
- [00:03:58.970]conditions, veg dry shows
- [00:04:00.400]relatively okay conditions for
- [00:04:02.590]most of the state of Nebraska.
- [00:04:04.900]Reasonably good conditions here
- [00:04:06.430]across the southern plains.
- [00:04:07.900]This isn't as good as it looked
- [00:04:09.290]earlier this summer.
- [00:04:10.480]But in general, especially here
- [00:04:12.310]across the northern plains,
- [00:04:13.950]conditions are much better than
- [00:04:15.690]they were a year ago.
- [00:04:17.040]Particularly the difference up
- [00:04:18.960]in South Dakota and western
- [00:04:20.600]North Dakota is relatively good.
- [00:04:21.000]And even some improvement in
- [00:04:23.890]Wyoming. Again, there are parts
- [00:04:26.320]and portions of the panhandle
- [00:04:27.820]that I still think are a bit on
- [00:04:29.260]the stress side. But yeah, much
- [00:04:31.150]better than a year ago.
- [00:04:32.640]In terms of record yields, so
- [00:04:34.740]again, this is not the most
- [00:04:36.000]recent quick drive map. I've
- [00:04:37.820]showed this a couple of
- [00:04:39.150]different places. So I put this
- [00:04:41.320]out in Market Journal last week.
- [00:04:43.660]And you know, this is maybe a
- [00:04:44.850]little bit easier viewing of it.
- [00:04:46.310]But these are basically what
- [00:04:47.510]the projected corn and soybean
- [00:04:48.870]yields were from last week.
- [00:04:50.160]I mean, they are more or less
- [00:04:52.310]projecting a national corn
- [00:04:53.950]yield of 188 bushels an acre
- [00:04:56.350]and a pretty strong soybean
- [00:04:58.180]yields as well.
- [00:04:59.560]And if you look at quick drive,
- [00:05:01.820]so which quick drive basically
- [00:05:04.110]is the combination of satellite
- [00:05:06.710]reflectance of vegetation
- [00:05:08.120]health.
- [00:05:08.800]So it shows that NDVI, the
- [00:05:10.150]enhanced vegetation index, and
- [00:05:12.160]also combines it with a
- [00:05:13.100]precipitation index to kind of
- [00:05:14.730]give you some assessment of how
- [00:05:16.360]conditions are.
- [00:05:17.560]So essentially, it's showing
- [00:05:19.120]that, you know,
- [00:05:20.160]Conditions are wet of an
- [00:05:21.090]average. You could interpret
- [00:05:22.450]this as meaning that vegetation
- [00:05:23.870]is probably certainly pretty
- [00:05:25.320]lush, likely pretty healthy.
- [00:05:26.640]And, you know, we have several
- [00:05:28.290]states that are likely to be
- [00:05:29.700]over 200 bushels an acre, at
- [00:05:31.550]least according to StoneX, they're
- [00:05:33.460]likely to be over 200 bushels
- [00:05:35.310]an acre.
- [00:05:36.040]With the brass coming in at 205
- [00:05:38.210]on corn and soybean at 63 bushels
- [00:05:40.380]an acre, this would tie the
- [00:05:41.990]soybean yield that was set in
- [00:05:43.680]2021 at 63 bushels an acre.
- [00:05:46.400]That 205, if that actually
- [00:05:48.600]would verify.
- [00:05:50.160]Later, you know, by early this
- [00:05:52.190]next year, if we could verify
- [00:05:53.410]that, that would not only be a
- [00:05:54.680]record, that would obliterate
- [00:05:55.840]the old record for the state,
- [00:05:57.400]which is sitting at 191.
- [00:05:59.160]I believe that will become just
- [00:06:00.400]short of record corn yields in
- [00:06:01.590]Illinois, and I believe that
- [00:06:02.780]would be just a little bit on
- [00:06:03.910]the record side in Iowa.
- [00:06:05.160]Again, I am concerned that some
- [00:06:07.200]places over here have probably
- [00:06:09.120]been just a little too wet of
- [00:06:10.830]late.
- [00:06:11.420]I'll show you here in a second
- [00:06:12.890]some of the reasons I'm a
- [00:06:14.120]little skeptical of some of
- [00:06:15.540]those highest in yield
- [00:06:16.730]projections coming to fruition.
- [00:06:20.160]In terms of heat units, though,
- [00:06:21.670]most everybody is probably at
- [00:06:22.920]or maybe slightly above where
- [00:06:24.220]you would normally be for
- [00:06:25.320]growing degree days.
- [00:06:26.520]And we were a little short
- [00:06:27.710]earlier in the summer.
- [00:06:29.000]So two months ago, we were a
- [00:06:30.320]little short here across some
- [00:06:31.720]of the region on heat units.
- [00:06:33.260]We generally have had warmer
- [00:06:34.530]overnight temperatures on
- [00:06:35.750]average, at least fairly
- [00:06:37.250]frequently here in the last
- [00:06:38.110]couple of months.
- [00:06:39.080]And we've had a couple of just
- [00:06:40.610]what we call pulses of heat.
- [00:06:42.100]So we have generally caught up
- [00:06:43.820]or maybe or just slightly above
- [00:06:45.410]where we would be on heat units.
- [00:06:47.300]But regardless, I don't think
- [00:06:48.940]there's any major.
- [00:06:50.340]Risk for anybody in the corn
- [00:06:51.530]belt of not having their crop
- [00:06:52.990]finished off before we have our
- [00:06:54.570]average first freeze date.
- [00:06:56.260]So what I'm showing you here is
- [00:06:58.380]the temp and precipitation quad
- [00:07:00.280]charts looking for the summer,
- [00:07:02.380]so the months of June and July
- [00:07:04.230]and for the left is the corn
- [00:07:05.910]belt as a whole from basically
- [00:07:07.850]central Nebraska through Ohio
- [00:07:09.890]and northeast Kansas up into
- [00:07:11.750]southeast North Dakota.
- [00:07:13.860]And then on the right is this
- [00:07:15.120]for Nebraska as a whole.
- [00:07:16.400]So you'll notice in both cases,
- [00:07:17.500]you know, we're kind of the
- [00:07:18.440]upper right quadrant warm and
- [00:07:19.450]wet being.
- [00:07:20.340]The case but for the corn belt
- [00:07:22.040]as a whole, I just want to
- [00:07:23.480]point out that, you know, we
- [00:07:25.410]are certainly wet of an average.
- [00:07:27.880]I mean, we are not many summers
- [00:07:29.620]to this point that have
- [00:07:30.900]actually been wetter than what
- [00:07:32.660]we've been so far in 2025,
- [00:07:34.670]which is certainly not what I
- [00:07:36.290]think anybody was projecting
- [00:07:38.000]six months ago.
- [00:07:39.300]I wasn't necessarily bullish on
- [00:07:41.280]us being over here, but I was
- [00:07:43.020]not projecting us to been here.
- [00:07:45.200]I think I was thinking that we
- [00:07:46.740]would probably be somewhere in
- [00:07:48.530]this rain closer to 20.
- [00:07:50.320]17 and maybe you're like 20, 21
- [00:07:53.210]over here somewhere.
- [00:07:54.920]Yeah, right here.
- [00:07:55.980]You'll notice, though, that the
- [00:07:57.720]years where we have generally
- [00:07:59.220]been below trend, you know, not
- [00:08:00.900]too surprising.
- [00:08:01.880]We have a lot of years in this
- [00:08:03.290]upper left quadrant where we
- [00:08:04.800]warm and dry, you know, 2012,
- [00:08:06.990]88, 02, 06, 2022.
- [00:08:09.600]You know, these are years we
- [00:08:11.120]generally were below trend or
- [00:08:12.720]maybe just right at trend.
- [00:08:14.340]You'll notice, though, too,
- [00:08:16.730]that being too wet is also not
- [00:08:18.800]necessary.
- [00:08:20.160]It's really a good thing.
- [00:08:20.660]So 2010 was very wet, wetter
- [00:08:22.580]than this year.
- [00:08:23.500]I'll talk about later why 2010
- [00:08:25.210]may be a useful analog.
- [00:08:26.340]And then, of course, 1993,
- [00:08:28.410]where we just had insane
- [00:08:29.670]amounts of precipitation here
- [00:08:31.320]across a lot of this region.
- [00:08:33.040]So there is definitely a thing
- [00:08:34.290]as too much water.
- [00:08:35.180]You'll notice our best years,
- [00:08:36.700]they don't tend to be the wettest
- [00:08:38.290]years.
- [00:08:38.840]They tend to be years where we
- [00:08:40.280]get just enough precipitation,
- [00:08:41.970]usually pretty timely
- [00:08:43.110]precipitation.
- [00:08:44.140]And also we keep those
- [00:08:45.150]temperatures down.
- [00:08:46.240]That means that we are getting
- [00:08:47.930]regular intrusions of cooler
- [00:08:49.680]air.
- [00:08:50.160]So while years like, again, I
- [00:08:52.580]mentioned in an article I wrote
- [00:08:55.030]last week that, you know, 2025
- [00:08:57.940]has some similarities to 1992
- [00:08:59.560]in the sense that both years
- [00:09:01.400]were rather dry at times in
- [00:09:03.170]spring and early summer.
- [00:09:05.120]And then we saw a shift over
- [00:09:06.590]toward wet late June and July.
- [00:09:08.480]And, you know, maybe that way
- [00:09:10.100]times the rest of summer.
- [00:09:11.600]We have definitely seen that.
- [00:09:14.120]But the biggest difference was
- [00:09:15.810]1992 was significantly cooler
- [00:09:18.240]than this year.
- [00:09:19.100]You know, again, that was year.
- [00:09:20.160]After Pinatubo, something that
- [00:09:21.920]that probably was probably
- [00:09:23.360]contributed somewhat to the
- [00:09:24.910]cooler temperatures.
- [00:09:26.300]But regardless, I mean, we're
- [00:09:28.130]running a full five, almost six
- [00:09:29.960]degrees warmer than where we
- [00:09:31.600]were in 1992.
- [00:09:33.220]So those overnight lows were
- [00:09:34.710]much lower that summer.
- [00:09:36.100]So I think if we actually had
- [00:09:37.520]temperatures that were closer
- [00:09:39.130]to here with maybe just
- [00:09:40.460]slightly less precipitation, I
- [00:09:42.130]do think that that 188 number
- [00:09:44.320]would probably verify maybe
- [00:09:46.090]even be over that.
- [00:09:49.100]The last time we talked, I
- [00:09:50.140]mentioned, you know, the Grand
- [00:09:51.470]Forks early 95 degree rule.
- [00:09:53.020]So, again, we had a heat wave
- [00:09:54.640]in North Dakota back in May.
- [00:09:56.300]So the years where we had
- [00:09:57.500]historically, at least since
- [00:09:59.140]the early 1980s, where we had
- [00:10:01.040]had temperatures hit that
- [00:10:02.360]threshold early in the season,
- [00:10:03.980]you know, July, we were pretty
- [00:10:05.600]warm across the north central U.S.
- [00:10:07.740]And, you know, while it wasn't
- [00:10:09.300]necessarily cool for most of
- [00:10:10.580]this region, we were a little
- [00:10:11.970]bit warm.
- [00:10:12.620]Iowa, Nebraska, Illinois, you
- [00:10:14.230]know, the heat was more
- [00:10:15.350]displaced further toward the
- [00:10:16.700]east.
- [00:10:17.200]I wouldn't say that this was a
- [00:10:18.250]particularly.
- [00:10:19.100]Useful predictor this year in
- [00:10:20.570]terms of temperatures, it was
- [00:10:22.030]certainly not a good predictor
- [00:10:23.530]for a drought.
- [00:10:24.500]We've been about the exact
- [00:10:25.840]opposite of that for a lot of
- [00:10:27.450]this region the last six weeks
- [00:10:28.750]or so.
- [00:10:29.300]The other reason, in addition
- [00:10:31.150]to the temperatures being
- [00:10:32.720]probably a bit warm, that I'm
- [00:10:34.500]not just super bullish on those
- [00:10:36.360]high end yields.
- [00:10:37.640]We've also had a lot of cloud
- [00:10:39.020]cover in this region of the
- [00:10:40.340]country the last, say, six
- [00:10:41.780]weeks, maybe two months.
- [00:10:43.340]We've also had a lot of
- [00:10:44.170]humidity.
- [00:10:44.760]So thanks to Eric Snodgrass for
- [00:10:46.700]providing this figure.
- [00:10:49.100]He shared this with me a couple
- [00:10:50.370]of days ago.
- [00:10:51.020]This is looking at the solar
- [00:10:52.270]radiation on these last 45 days.
- [00:10:54.100]So, again, a lot of cloud cover
- [00:10:55.220]at times.
- [00:10:55.720]We've also had, you know, at
- [00:10:56.930]times we've had some smoke
- [00:10:57.940]coming in from the north and
- [00:10:59.010]northeast.
- [00:10:59.760]So, again, this is basically
- [00:11:01.070]showing that our radiation has
- [00:11:02.380]been a little bit reduced.
- [00:11:03.660]Now, again, I don't think this
- [00:11:05.470]is enough to bring our yields
- [00:11:07.090]down to the 175 level or
- [00:11:08.780]anything like that.
- [00:11:10.260]But I do think this would be
- [00:11:11.700]potentially enough to keep us
- [00:11:13.380]from hitting that 188 mark.
- [00:11:15.480]I do anticipate us being much
- [00:11:17.160]closer to 182.
- [00:11:19.100]182 to 184 on corn than the 188
- [00:11:21.630]numbers.
- [00:11:22.240]In terms of relative humidity,
- [00:11:24.290]we also have been very humid so
- [00:11:26.170]far this summer.
- [00:11:27.500]So what I'm showing you here on
- [00:11:28.870]the left is a plot of surface
- [00:11:30.190]humidity.
- [00:11:30.820]And, you know, again, most of
- [00:11:32.470]the central U.S. has been more
- [00:11:34.310]humid than average,
- [00:11:35.250]particularly here across the
- [00:11:36.460]Great Plains region.
- [00:11:37.500]And a lot of this, now, again,
- [00:11:39.390]these date periods are not
- [00:11:40.930]identical.
- [00:11:41.840]Apologize for that.
- [00:11:43.760]But I just wanted to point out
- [00:11:44.990]that especially for the, you
- [00:11:46.270]know, the first half of summer,
- [00:11:47.860]we really had strong.
- [00:11:49.100]Strong high pressure, what we
- [00:11:50.880]kind of call expansive purbuta
- [00:11:52.370]high,
- [00:11:52.800]meaning that we were getting
- [00:11:54.170]that clockwise flow around this,
- [00:11:55.900]you know, broader area of high
- [00:11:56.950]pressure.
- [00:11:57.380]So we really had very open
- [00:11:58.850]access to the Gulf.
- [00:12:00.120]You know, we had pretty good
- [00:12:01.430]southerly flow coming into low
- [00:12:02.850]levels of the atmosphere,
- [00:12:04.240]relatively potent low-double
- [00:12:06.080]jet at times.
- [00:12:07.040]So we really were helping, you
- [00:12:09.150]know, get an atmosphere that
- [00:12:11.070]was more moist than average
- [00:12:12.760]across this region.
- [00:12:14.220]I also would point out that we
- [00:12:15.420]were, you know, very wet here
- [00:12:16.710]across the southern plains into
- [00:12:18.100]the southeast.
- [00:12:19.100]So we had a lot of extra, you
- [00:12:21.600]know, transpiration being
- [00:12:23.810]released from plants.
- [00:12:26.020]We had extra evaporation going
- [00:12:27.460]on.
- [00:12:27.760]So, I mean, we, you know, that
- [00:12:28.770]moisture that we were getting
- [00:12:29.700]from the Gulf, we were not
- [00:12:30.770]being,
- [00:12:31.160]it was not being robbed at all
- [00:12:33.110]by this region.
- [00:12:34.460]And so I think that we probably
- [00:12:36.220]were getting extra moisture evaporation
- [00:12:38.680]at times earlier in the summer.
- [00:12:40.740]So I think that there's just a
- [00:12:42.300]lot of reasons we have had
- [00:12:43.660]higher levels of humidity this
- [00:12:45.350]summer so far.
- [00:12:46.360]And again, there are a lot of
- [00:12:47.490]diseases.
- [00:12:48.100]You know, diseases.
- [00:12:49.100]You know, my understanding, as
- [00:12:50.370]I mentioned before, there are
- [00:12:51.560]diseases like pretty much any
- [00:12:52.550]type of condition.
- [00:12:53.280]Certainly, higher humidity is,
- [00:12:56.180]you know, benefits fungal
- [00:12:58.480]diseases.
- [00:12:59.600]We definitely have had a lot of
- [00:13:01.210]tar spot.
- [00:13:01.880]We've had a lot of southern
- [00:13:02.900]rust in places.
- [00:13:03.660]We've had white mold on soybean.
- [00:13:05.000]So we've had a lot of
- [00:13:05.900]conditions that I think have
- [00:13:07.300]been very optimal for more
- [00:13:08.650]disease issues.
- [00:13:09.660]Now, again, I know a lot of
- [00:13:11.080]people, you know, have sprayed
- [00:13:12.830]at least once or twice for
- [00:13:14.130]these types of diseases.
- [00:13:15.700]So I'm not necessarily
- [00:13:17.010]expecting there to be, you know,
- [00:13:19.140]a significant loss in yield
- [00:13:20.450]because of the diseases.
- [00:13:21.900]But I do think there could be
- [00:13:22.980]some yield loss because of
- [00:13:24.030]diseases, you know,
- [00:13:25.020]again, because of the relative
- [00:13:26.470]persistence of humidity.
- [00:13:27.800]And again, like southern rust
- [00:13:29.630]is one type of disease that
- [00:13:31.180]generally likes the heat.
- [00:13:32.940]So we have thankfully not had
- [00:13:34.260]what I would call just any
- [00:13:35.410]really prolonged stretches of
- [00:13:36.850]heat.
- [00:13:37.340]We certainly have had stretches
- [00:13:38.850]where it had been warmer at
- [00:13:40.040]night with higher humidity
- [00:13:41.310]levels.
- [00:13:41.880]And then these, you know,
- [00:13:42.930]pulses of heat had probably
- [00:13:43.930]been somewhat favorable for its
- [00:13:45.140]expansion.
- [00:13:45.760]A quick look at soil
- [00:13:47.190]temperatures across the state.
- [00:13:48.860]Nebraska, mostly mid-60s to low-70s.
- [00:13:51.800]So again, these are about where
- [00:13:53.300]we would think you would be
- [00:13:54.710]this time of year.
- [00:13:55.500]Again, we have not necessarily
- [00:13:57.120]had any prolonged stretches
- [00:13:58.630]where the soil temperatures
- [00:13:59.930]have been significantly on the
- [00:14:01.310]high end.
- [00:14:01.920]Looking, kind of getting into
- [00:14:04.640]the outlook portion.
- [00:14:06.760]So in the short term, I do
- [00:14:08.710]think what we're likely to see
- [00:14:10.300]as we head into next week is
- [00:14:12.120]this ridge probably anchoring
- [00:14:13.430]itself over the southwestern
- [00:14:14.680]United States.
- [00:14:15.460]Now, again, that is a bit of a
- [00:14:16.710]different projection that we
- [00:14:17.960]were looking at.
- [00:14:18.820]You know, four or five days ago,
- [00:14:20.420]late last week, I think there
- [00:14:21.860]was more anticipation of this
- [00:14:23.320]ridge being a little bit more
- [00:14:24.710]anchored central east.
- [00:14:26.240]And that was going to probably
- [00:14:27.350]really crank up the heat.
- [00:14:28.440]I think we're going to crank up
- [00:14:29.710]the heat later this week.
- [00:14:31.000]We're likely to bring, you know,
- [00:14:32.480]as this ridge comes back toward
- [00:14:33.830]the west, we get back a little
- [00:14:35.110]bit more of a northwesterly
- [00:14:36.320]flow.
- [00:14:36.860]We are likely to probably get a
- [00:14:37.960]cold front to move through the
- [00:14:39.070]region as we head toward the
- [00:14:40.100]end of the weekend.
- [00:14:40.960]I do think that's going to
- [00:14:41.830]bring a chance of storms,
- [00:14:42.760]certainly the northern plains
- [00:14:43.820]and upper Midwest.
- [00:14:44.660]I do think even portions of
- [00:14:47.480]central east.
- [00:14:48.820]And eastern Nebraska, western
- [00:14:50.090]Iowa, probably even maybe
- [00:14:51.170]extreme northeast Kansas is
- [00:14:52.290]going to have pretty good
- [00:14:53.270]chances of rain early this next
- [00:14:54.780]week.
- [00:14:55.220]And also some chances for some
- [00:14:56.730]cooler temperatures to come
- [00:14:58.190]back in.
- [00:14:58.800]Now, the European extended
- [00:15:00.970]forecast was showing, you know,
- [00:15:02.880]maybe a bit drier signals we
- [00:15:04.640]had toward the end of the month.
- [00:15:06.920]So, again, there's been some
- [00:15:08.760]disagreement in the models here
- [00:15:10.680]in the last couple of days as
- [00:15:12.370]exactly how August is going to
- [00:15:14.080]finish out.
- [00:15:15.060]The artificial intelligence
- [00:15:16.740]runs are showing, you know, or
- [00:15:18.540]not.
- [00:15:18.780]Not necessarily showing any
- [00:15:19.920]prolonged period of dryness.
- [00:15:21.160]Certainly once you get Kansas-Nebraska
- [00:15:23.150]border northward through the
- [00:15:24.630]north central region.
- [00:15:25.960]So, you know, there is a
- [00:15:27.140]possibility we could see things
- [00:15:28.680]go over a little bit drier.
- [00:15:30.140]But I think the more likely
- [00:15:32.020]scenarios that we kind of keep
- [00:15:33.780]the faucet on, certainly the I-80
- [00:15:36.330]corridor north for the next 10
- [00:15:38.510]days.
- [00:15:39.120]So, again, if you're not
- [00:15:40.340]wanting more precipitation in
- [00:15:41.770]Iowa, I don't necessarily have
- [00:15:43.250]the best news for you.
- [00:15:44.480]I think that it's probably
- [00:15:45.820]likely to continue for the next
- [00:15:47.400]couple of weeks.
- [00:15:48.580]At least there's going to be a
- [00:15:49.460]chance of it continuing for the
- [00:15:50.580]next couple of weeks.
- [00:15:51.300]The good news, though, is that
- [00:15:53.050]I do think the heat, I do
- [00:15:54.440]certainly anticipate there's
- [00:15:56.040]going to be some more hot days
- [00:15:57.590]coming up.
- [00:15:58.400]I do not think we are looking
- [00:15:59.680]at any really prolonged
- [00:16:00.860]stretches of heat.
- [00:16:01.880]I do not think we're looking at
- [00:16:03.150]a repeat of what we saw two
- [00:16:04.300]years ago around August 18th,
- [00:16:05.750]you know, through the 24th.
- [00:16:07.440]Not looking at that coming in,
- [00:16:09.000]it looks like.
- [00:16:09.860]CPC is three to four week
- [00:16:11.050]temperature outlook.
- [00:16:12.320]So, again, they're showing warm
- [00:16:13.680]east, warm west, and, you know,
- [00:16:15.080]kind of favoring maybe, you
- [00:16:16.210]know, some more systems coming
- [00:16:18.030]into.
- [00:16:18.460]The north central United States.
- [00:16:19.620]So, again, this was issued last
- [00:16:21.430]Friday.
- [00:16:22.040]So, they are probably showing,
- [00:16:23.720]you know, more ridging east and
- [00:16:25.100]west, more troughs maybe
- [00:16:26.320]getting into southern Canada,
- [00:16:27.940]maybe the north central U.S.
- [00:16:29.540]So, I do think that this would
- [00:16:30.960]indicate that there's going to
- [00:16:32.450]be chances of getting more
- [00:16:33.890]precipitation in this region as
- [00:16:35.240]we head into Labor Day.
- [00:16:36.440]And also probably not going to
- [00:16:37.980]turn off the faucet.
- [00:16:39.200]I, this certainly, particularly
- [00:16:41.460]the, you know, the western side
- [00:16:43.550]of this, I'm a little bit
- [00:16:45.110]skeptical that northern
- [00:16:46.690]Illinois and Wisconsin,
- [00:16:48.340]will be below average.
- [00:16:49.340]Possibly we could stay below
- [00:16:50.780]average here on the eastern
- [00:16:52.160]side of the Great Lakes.
- [00:16:53.520]Looking at sea surface
- [00:16:55.930]temperature anomalies right now.
- [00:16:57.740]So, you know, the area where we'd
- [00:16:59.260]look for ENSO, Central and
- [00:17:00.390]Eastern Equatorial Pacific, you
- [00:17:01.960]know, we are essentially kind
- [00:17:03.690]of in what we call neutral
- [00:17:05.050]conditions.
- [00:17:06.020]You know, we've had a little
- [00:17:07.290]bit more pronounced easterly
- [00:17:08.600]wind flow here, a little bit
- [00:17:09.860]more westerly wind anomalies
- [00:17:11.160]here closer towards South
- [00:17:12.320]America.
- [00:17:13.020]So, some warmer water off the
- [00:17:14.340]coast of South America, but,
- [00:17:15.720]you know, cooler here.
- [00:17:17.000]So, we were essentially.
- [00:17:18.220]Effectively neutral.
- [00:17:19.260]And I, the expectation is that
- [00:17:21.300]we are likely to probably stay
- [00:17:22.510]neutral.
- [00:17:23.060]Maybe there's a slight chance
- [00:17:24.890]we get into La Nina as we head
- [00:17:26.550]into later in the fall.
- [00:17:27.940]El Nino seems to be a
- [00:17:29.710]relatively lower probability.
- [00:17:33.020]Again, pretty warm here across
- [00:17:34.530]a lot of the Atlantic, although
- [00:17:36.040]certainly not as warm as last
- [00:17:37.380]year.
- [00:17:37.860]So, that's one of the reasons,
- [00:17:39.070]you know, this area being a
- [00:17:40.090]little bit cooler is one of the
- [00:17:41.200]reasons we haven't seen as many
- [00:17:42.370]storms develop.
- [00:17:43.220]There's other reasons we haven't
- [00:17:44.900]seen that as well.
- [00:17:45.980]But I just want to point out
- [00:17:47.400]how warm.
- [00:17:48.100]The North Pacific's been.
- [00:17:49.100]So, earlier in the, you know,
- [00:17:50.890]back in the spring, you know,
- [00:17:52.760]we were talking about the
- [00:17:54.040]forecast for the summer.
- [00:17:55.740]I said, you know, what happens
- [00:17:56.940]up here is going to be very
- [00:17:57.880]crucial.
- [00:17:58.360]I said, you know, this is
- [00:17:59.540]likely to be cooler.
- [00:18:00.620]You know, if this was also cool,
- [00:18:02.360]then the risk of having ridging
- [00:18:03.990]being prominent somewhere
- [00:18:05.470]between, you know, the Cascades
- [00:18:07.480]and the Great Lakes is going to
- [00:18:09.060]be relatively high.
- [00:18:10.360]And one of the reasons we haven't
- [00:18:12.140]maintained a strong ridge
- [00:18:13.590]anywhere in the central U.S.
- [00:18:15.510]for any period of time is, I
- [00:18:16.480]think, because we have had.
- [00:18:17.980]You know, we've had warmer
- [00:18:18.490]water.
- [00:18:18.680]We've had atmosphere.
- [00:18:19.440]We generally maintain some flow
- [00:18:22.030]in the atmosphere.
- [00:18:23.820]So, that's really helped push
- [00:18:25.380]this warmer water further east.
- [00:18:27.140]And, again, we've had a lot of
- [00:18:28.690]ridging over Japan and Korea
- [00:18:30.140]this summer.
- [00:18:31.020]So, we've had very, very warm
- [00:18:32.060]water temperatures here.
- [00:18:33.100]You know, I'll talk about 2010
- [00:18:35.580]a little bit later.
- [00:18:36.940]But just one key difference in
- [00:18:38.190]2010 is by this time in 2010,
- [00:18:40.240]we were basically already in a
- [00:18:41.510]full-blown La Nina.
- [00:18:42.580]That is absolutely not the case
- [00:18:44.480]at the present time.
- [00:18:45.800]There's then some forecasts.
- [00:18:47.860]You know, again, not really
- [00:18:48.840]showing any strong signal.
- [00:18:49.740]There might be a little better
- [00:18:50.860]chance of La Nina.
- [00:18:51.700]You know, there's one model
- [00:18:53.170]that is showing us maybe being
- [00:18:54.710]weakly in El Nino.
- [00:18:55.840]But, again, the consensus right
- [00:18:57.620]now is probably remaining about
- [00:18:59.240]neutral.
- [00:18:59.920]Not any, probably remaining
- [00:19:01.590]that way through the winter.
- [00:19:03.160]CBC's most recent drought was
- [00:19:05.660]released at the end of July.
- [00:19:08.180]You know, again, they are
- [00:19:09.450]showing drought development
- [00:19:10.890]being possible or even likely
- [00:19:12.250]across portions of the central
- [00:19:13.720]plains.
- [00:19:14.300]You know, interestingly enough,
- [00:19:16.330]they're not showing any.
- [00:19:17.740]We signal for drought here
- [00:19:18.940]across the southern plains and
- [00:19:20.380]getting into the mid-south
- [00:19:21.600]region.
- [00:19:22.160]Given that it's been pretty dry
- [00:19:23.910]down here, you know, in the
- [00:19:25.510]last, you know, say, month to
- [00:19:27.310]six weeks while it's been wetter
- [00:19:28.850]up here.
- [00:19:29.300]You know, just because of that
- [00:19:31.120]and recent precedent and, you
- [00:19:33.190]know, I think what you see in
- [00:19:34.620]the, some of the outlooks,
- [00:19:36.340]I do think there's going to be
- [00:19:37.430]a potential to see some drought
- [00:19:38.620]conditions develop here across
- [00:19:39.870]this region.
- [00:19:40.580]We've also been very dry across
- [00:19:42.250]New England the last couple of
- [00:19:43.970]months.
- [00:19:44.520]So, I'm just really kind of
- [00:19:45.930]curious.
- [00:19:46.600]I mean, I think they're
- [00:19:47.200]expecting.
- [00:19:47.620]Precipitation to be above
- [00:19:49.100]average as fall, which is why
- [00:19:50.640]they didn't paint this area in
- [00:19:51.760]with the drought development.
- [00:19:52.920]But again, the rain is going to
- [00:19:54.650]have to turn on relatively soon
- [00:19:55.630]here in upstate New York and
- [00:19:56.700]New England, or we will be
- [00:19:58.330]seeing drought there.
- [00:19:59.400]Also, we've been sneaky dry
- [00:20:00.940]here across portions of the
- [00:20:02.430]Sandhills in South Dakota, so I
- [00:20:04.520]would anticipate there may be
- [00:20:05.860]being some drought pressure
- [00:20:06.940]coming back into this region if
- [00:20:08.580]we don't, you know, start
- [00:20:10.510]getting more regular
- [00:20:11.280]precipitation in that area.
- [00:20:12.420]CBC shows below average
- [00:20:14.020]favorite across most of the
- [00:20:15.860]Great Plains region.
- [00:20:17.500]Through the fall, wet Eastern
- [00:20:19.420]Corn Belt and Mid-Atlantic
- [00:20:20.850]region, warm pretty much
- [00:20:22.140]everywhere in the U.S.
- [00:20:23.560]European actually has a little
- [00:20:26.420]different, again, they're in
- [00:20:28.460]pretty good agreement with the
- [00:20:29.760]temperatures being above
- [00:20:30.860]average.
- [00:20:31.380]And they're above, they're, you
- [00:20:32.830]know, in somewhat agreement
- [00:20:34.100]with temperatures, sorry, with
- [00:20:35.620]precipitation being below
- [00:20:36.710]average here across parts of
- [00:20:37.980]the Northern Plains.
- [00:20:38.920]But they are showing a bit of a
- [00:20:40.420]wet signal across the, you know,
- [00:20:42.290]portion of the Central Plains
- [00:20:43.800]and Western Corn Belt, which I
- [00:20:45.850]have to add is, you know,
- [00:20:47.380]very different what they've
- [00:20:48.810]been, they've been, you know,
- [00:20:50.500]for most of the summer, they
- [00:20:51.920]were kind of on this, you know,
- [00:20:53.760]path of going to be warm and
- [00:20:55.110]dry,
- [00:20:55.460]come hell or high water, you
- [00:20:57.020]know, the warm is generally
- [00:20:58.580]verified, but the dry is
- [00:20:59.940]definitely not.
- [00:21:01.100]And they, you know, this
- [00:21:02.420]outlook that was released
- [00:21:03.760]earlier in the month does show
- [00:21:05.310]that there may be some chances
- [00:21:06.780]of getting better precipitation
- [00:21:08.580]than we've had in recent falls
- [00:21:10.360]in this area.
- [00:21:11.340]And again, while I'm not,
- [00:21:13.290]certainly not wishing for a
- [00:21:15.120]significant harvest delay,
- [00:21:17.260]it would be very nice to
- [00:21:18.720]actually go into the cold
- [00:21:20.350]season, this, you know, this
- [00:21:22.660]coming cold season, having a
- [00:21:23.810]full profile of soil moisture.
- [00:21:25.440]We have not had that in, at
- [00:21:26.580]least in most Nebraska in
- [00:21:27.690]several years.
- [00:21:28.580]So it'd be nice to actually
- [00:21:29.680]have that for a change.
- [00:21:30.780]But as I mentioned, recent
- [00:21:33.000]falls have been pretty warm and
- [00:21:35.090]dry.
- [00:21:35.720]So if you look at just where we,
- [00:21:36.930]you know, the last five fall
- [00:21:38.080]swings, so this decade to this
- [00:21:39.450]point, 2020 through 2024,
- [00:21:41.540]we have been generally dry and
- [00:21:43.470]warm pretty much across the
- [00:21:45.010]entire U.S. with the exception
- [00:21:46.720]of places,
- [00:21:47.140]where we've had a lot of
- [00:21:48.520]tropical activity, Florida, and
- [00:21:50.440]then, you know, again, this,
- [00:21:51.200]you know,
- [00:21:51.460]district of North Carolina,
- [00:21:52.830]where we've had a lean last
- [00:21:54.020]year with record precipitation,
- [00:21:55.700]and generally warm just pretty
- [00:21:57.280]much everywhere in the lower 48.
- [00:21:59.100]And the reason for that, you
- [00:22:00.610]know, if you look at the last
- [00:22:02.190]five years, where the jet
- [00:22:03.490]stream has been,
- [00:22:04.560]well, we've had, this is
- [00:22:05.850]showing anomalies of the zolder
- [00:22:07.430]wind.
- [00:22:07.920]So, you know, these cooler
- [00:22:09.270]colors here means that we've
- [00:22:10.600]had lower wind speeds than
- [00:22:11.830]average,
- [00:22:12.440]higher wind speeds than average
- [00:22:14.090]here.
- [00:22:14.560]So basically, we've had a
- [00:22:15.610]displaced northward,
- [00:22:17.020]north Pacific jet, meaning that
- [00:22:18.630]the storm track has remained
- [00:22:20.940]generally north of lower 48 in
- [00:22:23.030]the fall.
- [00:22:23.800]It's certainly at least like
- [00:22:25.060]the early mid-portion of the
- [00:22:26.320]fall in recent years.
- [00:22:27.460]You know, again, some of this
- [00:22:28.720]is just a climate change signal,
- [00:22:30.160]you know, with the, you know,
- [00:22:31.740]we've warmer, a lot warmer up
- [00:22:33.300]here than we used to be in the
- [00:22:34.710]early mid-portion of the fall.
- [00:22:36.640]So that temperature gradient
- [00:22:37.840]isn't quite as strong as it
- [00:22:38.870]used to be.
- [00:22:39.520]You know, these jets are thermally
- [00:22:40.920]driven, meaning that, you know,
- [00:22:42.380]that we probably have our
- [00:22:43.430]stronger temperature gradients
- [00:22:44.830]a bit further north than we
- [00:22:45.930]used to in the fall.
- [00:22:46.900]So that's one reason, I think,
- [00:22:48.580]that we've seen this
- [00:22:49.380]displacement of a north Pacific
- [00:22:51.260]jet,
- [00:22:51.640]even though I would say that's
- [00:22:52.890]probably not the only reason.
- [00:22:54.280]And again, just for the state
- [00:22:56.210]of Nebraska, you know,
- [00:22:57.540]we have tended to be pretty
- [00:22:58.510]warm in the falls in recent
- [00:22:59.480]years.
- [00:22:59.880]We have not had many cool falls
- [00:23:01.560]so far in the 21st century,
- [00:23:03.420]and the expectation is not for
- [00:23:05.350]one this year.
- [00:23:06.480]But, you know, again, if we
- [00:23:07.850]keep getting these troughs
- [00:23:09.130]coming in,
- [00:23:09.760]you know, we may not
- [00:23:10.820]necessarily be as warm in the
- [00:23:12.530]fall as we've been in recent
- [00:23:13.750]years.
- [00:23:16.780]I mentioned earlier that 2010
- [00:23:19.210]might be a useful analog.
- [00:23:20.760]And, you know, again, this
- [00:23:23.090]summer has not been remotely
- [00:23:24.310]identical to 2010,
- [00:23:25.620]but there are some similarities.
- [00:23:27.160]You know, in particular, we've
- [00:23:29.400]had more ridging across the
- [00:23:31.540]east this summer than what we,
- [00:23:33.500]you know, that we've probably
- [00:23:34.540]had in recent years.
- [00:23:35.340]So 2010, we had quite a bit of
- [00:23:37.340]ridging in the middle upper
- [00:23:39.000]atmosphere, you know, across
- [00:23:40.510]the eastern U.S.
- [00:23:41.380]We were generally drier than
- [00:23:42.380]average across a lot of the mid-south
- [00:23:43.970]through the up and through New
- [00:23:45.360]England.
- [00:23:45.660]That's kind of been the case.
- [00:23:46.660]Particularly in the last six
- [00:23:48.440]weeks or so, much wetter signal
- [00:23:50.030]here across the western and
- [00:23:51.260]central Corn Belt,
- [00:23:52.160]similar to this year.
- [00:23:53.700]So notice, like, for example,
- [00:23:55.410]Des Moines, you know, 2025,
- [00:23:57.500]the last, you know, 40 days
- [00:23:59.060]from July 1st through August 9th
- [00:24:00.790]was wettest on record.
- [00:24:02.040]2010 was fourth wettest.
- [00:24:03.780]So, again, I think that there
- [00:24:05.000]are some similarities into, you
- [00:24:06.890]know,
- [00:24:07.040]how the last six weeks have
- [00:24:08.150]transpired is similar to 2010.
- [00:24:10.060]So I do think that 2010 is
- [00:24:12.410]possibly a useful analog.
- [00:24:14.260]I can't really think of any.
- [00:24:16.540]Any other analogs right now
- [00:24:18.080]that I think really stand out
- [00:24:19.620]as being extremely useful.
- [00:24:21.160]21 might be slightly useful,
- [00:24:23.780]but, you know, this year is not
- [00:24:25.140]really shaped up like 21 in a
- [00:24:28.270]real meaningful way.
- [00:24:29.400]For the fall as a whole in 2010,
- [00:24:32.600]we were a little drier across
- [00:24:35.340]the, you know, across Nebraska.
- [00:24:37.040]So, again, the European model
- [00:24:38.060]is showing that there was maybe
- [00:24:39.280]some chance of above average
- [00:24:40.410]precipitation in this region.
- [00:24:41.940]So that certainly would not be
- [00:24:42.940]in agreement with it, you know,
- [00:24:44.680]kind of a mix of wet and dry
- [00:24:46.420]across most of Nebraska.
- [00:24:46.420]So, again, I think, you know,
- [00:24:56.780]barring, you know, getting
- [00:24:58.260]tropical storm activity,
- [00:24:59.120]I do think that there is going
- [00:25:00.560]to be a risk of, you know,
- [00:25:01.900]getting some drought to develop
- [00:25:02.900]down in this region of the
- [00:25:03.670]country.
- [00:25:04.120]You know, again, we were a bit
- [00:25:05.590]wetter here across the
- [00:25:06.670]northeast.
- [00:25:07.440]So that is, you know, I think
- [00:25:08.940]that is one indication that,
- [00:25:10.440]you know, if recent precedent
- [00:25:12.340]or at least like the forecast
- [00:25:13.590]plus this actually were to come
- [00:25:14.950]to fruition,
- [00:25:15.660]we would probably, you know, we
- [00:25:15.950]would be a little bit wetter.
- [00:25:16.300]We would probably reduce that
- [00:25:17.570]drought risk in this region a
- [00:25:18.790]good bit.
- [00:25:19.360]And, again, we were pretty warm
- [00:25:21.180]across a lot of the central U.S.
- [00:25:23.170]in the fall.
- [00:25:24.000]So, again, I am more confident
- [00:25:25.670]in us staying relatively warm
- [00:25:27.200]for most of fall.
- [00:25:28.340]I am a little bit less
- [00:25:29.230]confident on any sort of
- [00:25:30.270]precipitation signal.
- [00:25:31.520]Turns out what is going on just,
- [00:25:33.420]you know, from an ocean and
- [00:25:34.780]atmospheric standpoint in 2010.
- [00:25:37.300]So what we had that year, so,
- [00:25:39.170]again, now in contrast to this
- [00:25:41.150]year, we really just have just
- [00:25:42.720]truly inso neutral conditions.
- [00:25:44.200]We had a full-blown lot.
- [00:25:46.180]I mean, at this point in 2010
- [00:25:47.370]or, you know, by early
- [00:25:48.090]September.
- [00:25:48.680]So, you know, cold central east
- [00:25:50.650]and, you know, cold off the
- [00:25:52.330]coast of California.
- [00:25:53.840]Still pretty warm here.
- [00:25:55.480]But, again, this, you know,
- [00:25:56.470]this is similar.
- [00:25:57.180]This is certainly not.
- [00:25:58.840]So, again, I would take the
- [00:26:01.310]2010 analog with a grain of
- [00:26:03.790]salt.
- [00:26:04.500]I do think there's a
- [00:26:05.200]possibility that we may see
- [00:26:06.170]similarities.
- [00:26:06.880]But I certainly am not
- [00:26:08.390]anticipating, you know, this
- [00:26:10.450]fall to look exactly like 2010.
- [00:26:13.180]But what we saw that year,
- [00:26:15.140]especially in the first.
- [00:26:16.060]You know, like, especially mid-September
- [00:26:17.980]through a lot of October, early
- [00:26:19.320]November, you know, we had more
- [00:26:20.920]ridging, more southwestward
- [00:26:23.860]displacement, the Pacific high
- [00:26:25.160]closer toward Japan, a lot of
- [00:26:27.030]troughing, north Pacific,
- [00:26:28.060]particularly here off the Gulf
- [00:26:29.480]of Alaska, ridge here, a lot of
- [00:26:31.640]the central, you know, rocky
- [00:26:33.300]mountain region toward Great
- [00:26:34.650]Lakes, we had ridging, deep trough
- [00:26:36.370]in the northeast.
- [00:26:37.420]So, again, you know, wetter
- [00:26:38.890]signal there, you know, a
- [00:26:40.190]little bit more mixed
- [00:26:41.230]precipitation across parts of
- [00:26:42.710]central U.S., drier signal
- [00:26:44.290]across the southeast.
- [00:26:45.800]So, again, this type of pattern
- [00:26:47.910]would favor, you know,
- [00:26:49.510]certainly being warm and
- [00:26:51.070]probably not super, super wet
- [00:26:53.030]for most people.
- [00:26:54.360]Certainly, you know, I think
- [00:26:56.150]south of I-90, I don't think
- [00:26:57.960]that would be a particularly
- [00:26:59.580]wet signal for most of us.
- [00:27:01.300]Now, again, this, what I'm
- [00:27:03.340]showing you here, if this doesn't
- [00:27:04.890]make any sense to you, that
- [00:27:06.390]just means you're a normal
- [00:27:07.790]human being.
- [00:27:08.800]But this, what I'm looking at
- [00:27:10.500]here is just the velocity
- [00:27:11.630]potential to see where we had
- [00:27:13.090]most arising motion.
- [00:27:14.440]And this is.
- [00:27:15.760]This is kind of an indication
- [00:27:17.090]where the MGO was most active
- [00:27:18.450]in the fall of 2010.
- [00:27:19.960]And, you know, again, we had
- [00:27:21.900]more sinking motion across the
- [00:27:23.830]eastern Pacific, more rising
- [00:27:25.820]motion here across Australia,
- [00:27:27.790]Indonesia.
- [00:27:28.780]That means that we were
- [00:27:30.190]spending more time in phases
- [00:27:32.000]four and three, four and five
- [00:27:34.160]that fall.
- [00:27:34.760]We are starting to see
- [00:27:35.890]indications that we may or may
- [00:27:37.450]be a little bit more bullish in,
- [00:27:39.140]you know, phases four and five
- [00:27:40.770]with the MGO.
- [00:27:41.760]So we may be more active in
- [00:27:43.120]this region of the world.
- [00:27:44.660]You know, again, that does.
- [00:27:45.720]It does tend to have a, an
- [00:27:46.930]impact on where you put ridges
- [00:27:48.310]and troughs.
- [00:27:49.120]And I would just say that, you
- [00:27:50.870]know, especially once you get
- [00:27:52.700]into later September, October,
- [00:27:54.750]you know, an active MGO in that
- [00:27:56.930]region of the world does tend
- [00:27:59.120]to favor a pattern.
- [00:28:00.520]It looks a bit more like this
- [00:28:01.960]with troughing off, you know,
- [00:28:03.650]south of Alaska, more ridging
- [00:28:05.280]here, troughing here.
- [00:28:06.860]So again, that, that may be a
- [00:28:08.270]signal that we may be headed
- [00:28:09.590]toward a pattern that looks a
- [00:28:10.970]bit more like that.
- [00:28:12.220]But I'm not overly confident
- [00:28:14.200]that we are going.
- [00:28:15.780]To spend the entire fall in
- [00:28:17.660]phases four and five of the MGO.
- [00:28:20.240]Just for a quick reference,
- [00:28:21.840]since we are getting, you know,
- [00:28:23.100]in deeper into August, some of
- [00:28:24.530]us will have to start being
- [00:28:25.750]concerned about freezes here in
- [00:28:27.240]about another month,
- [00:28:28.300]particularly, you know, getting
- [00:28:29.950]into the Dakotas, Western
- [00:28:31.330]Nebraska, certainly the higher
- [00:28:32.770]elevations out here.
- [00:28:34.160]We do tend to start having
- [00:28:35.570]light freezes in the second
- [00:28:36.920]half of September.
- [00:28:38.100]So the Midwest Regional Climate
- [00:28:40.100]Center has a very good frost
- [00:28:41.780]freeze date tool.
- [00:28:43.120]So you can look at trends.
- [00:28:45.520]You can look at the first
- [00:28:46.390]freeze date and you can, you
- [00:28:47.300]know, do it by temperature.
- [00:28:48.400]So this was 32, which you can
- [00:28:50.250]go down to 28 and 24.
- [00:28:52.020]Just kind of look at the, you
- [00:28:53.110]know, the truly killing frost.
- [00:28:54.520]And it'll show by, you know,
- [00:28:56.140]average for your county based
- [00:28:57.760]on historical records.
- [00:28:59.280]So it goes here for Sioux
- [00:29:00.280]County, which is a far
- [00:29:01.230]northwestern county here in
- [00:29:02.430]Nebraska.
- [00:29:03.000]We tend to have our average
- [00:29:04.250]first fall freeze in September
- [00:29:05.720]27th.
- [00:29:06.400]You need to get closer to southeastern
- [00:29:07.530]Nebraska.
- [00:29:07.940]It tends to be closer toward
- [00:29:08.880]the middle of October.
- [00:29:09.780]So again, we tend to have our
- [00:29:11.010]first freeze, you know, a
- [00:29:12.190]little bit later in September
- [00:29:13.470]up in this region.
- [00:29:15.360]And given that we are not real
- [00:29:17.090]short on GDDs up here,
- [00:29:18.480]I'm not super concerned about
- [00:29:21.070]not getting the heat units that
- [00:29:23.760]we need before we finish out
- [00:29:25.920]the fall.
- [00:29:26.780]To summarize, we have had a
- [00:29:28.880]weather and expected summer.
- [00:29:31.440]Again, I was not on the bandwagon
- [00:29:33.300]for a doomsday drought across
- [00:29:34.960]this region,
- [00:29:35.880]but I did think that there was
- [00:29:37.180]going to be drought pressure,
- [00:29:38.700]particularly in the western
- [00:29:39.930]side of the Corn Belt Central
- [00:29:41.140]Plains.
- [00:29:41.660]That did not come to fruition.
- [00:29:43.000]We've been much wetter than
- [00:29:44.250]average across.
- [00:29:45.200]A lot of especially the last
- [00:29:46.370]six weeks or so.
- [00:29:47.160]We've also been cloudier, more
- [00:29:48.640]humid than average.
- [00:29:49.760]I do think yields are likely to
- [00:29:51.530]be good,
- [00:29:52.100]but I do think those higher in
- [00:29:54.120]yields from some of the
- [00:29:55.730]analysts,
- [00:29:56.620]I do think those will be harder
- [00:29:58.000]to achieve,
- [00:29:58.640]particularly if we maintain
- [00:30:01.420]more cloud cover and more
- [00:30:03.550]disease pressure in the next
- [00:30:05.140]three to four weeks.
- [00:30:06.340]But anybody that is just
- [00:30:08.140]slightly short on moisture,
- [00:30:10.420]I do think there is going to be
- [00:30:11.660]chances of getting the moisture
- [00:30:13.060]you need.
- [00:30:15.040]The upside is we are likely to
- [00:30:17.330]see more heat in the next two
- [00:30:18.990]or three weeks.
- [00:30:19.720]But as has been the story this
- [00:30:21.690]summer,
- [00:30:22.380]we have not seen prolonged heat
- [00:30:24.390]anywhere in this region so far
- [00:30:26.570]this summer,
- [00:30:27.340]at least for maximum
- [00:30:28.520]temperatures.
- [00:30:29.220]We've definitely been warm
- [00:30:30.170]overnight, particularly the
- [00:30:31.260]eastern Corn Belt.
- [00:30:31.980]But I don't think we're likely
- [00:30:33.750]to look,
- [00:30:34.360]we're not looking at any major,
- [00:30:35.820]you know, 10-day heat waves
- [00:30:37.340]coming in.
- [00:30:37.940]Heat's going to be in pulses.
- [00:30:39.060]I do think if you are listening
- [00:30:41.230]to this in Kansas and to the
- [00:30:43.050]southern portion of the Plains,
- [00:30:45.140]the faucet may turn off here
- [00:30:46.400]the last part of the month.
- [00:30:47.900]I do think there's a chance it's
- [00:30:49.110]going to stay on the Corn Belt,
- [00:30:50.330]though.
- [00:30:50.860]I do not see a lot of our
- [00:30:52.220]region, certainly central
- [00:30:54.090]Nebraska into Illinois,
- [00:30:55.900]I do not see us going over just
- [00:30:57.250]bone dry through the rest of
- [00:30:58.560]the month.
- [00:30:59.260]Recent precedent would suggest
- [00:31:01.320]we will be warmer than average
- [00:31:03.210]in fall and not super wet.
- [00:31:05.020]2010 may be useful analog, but
- [00:31:07.090]don't expect it to be identical.
- [00:31:08.960]And again, I'm not seeing signs
- [00:31:11.390]yet for an early fall freeze in
- [00:31:13.640]the Corn Belt.
- [00:31:14.920]I'm not seeing signs yet for an
- [00:31:14.920]early fall freeze in the Corn
- [00:31:14.920]Belt.
- [00:31:14.980]I'm not seeing signs yet for an
- [00:31:14.980]early fall freeze in the Corn
- [00:31:14.980]Belt.
- [00:31:15.000]And I have not really, to be
- [00:31:16.860]honest, I have not spent a
- [00:31:18.160]whole lot of time taking a
- [00:31:19.220]really good look
- [00:31:20.420]at what we may be in for this
- [00:31:21.510]winter.
- [00:31:21.840]But, you know, at this point,
- [00:31:24.230]it is really pretty early to
- [00:31:26.300]kind of have any meaningful
- [00:31:28.200]forecast
- [00:31:29.340]for the winter other than we're
- [00:31:30.900]going to have it.
- [00:31:31.920]So that's my story for the
- [00:31:33.740]month.
- [00:31:34.500]I will, if you have any
- [00:31:36.020]questions, you are welcome to
- [00:31:38.120]contact me at the email address,
- [00:31:40.220]ehunt2 at unl.edu.
- [00:31:42.240]Again, if you're in Nebraska,
- [00:31:43.510]you can find me on Marketplace.
- [00:31:44.980]Journal on Saturday mornings,
- [00:31:45.980]the CropWatch podcast, and nsco.unl.edu.
- [00:31:50.920]Thanks for listening.
