It's a holiday weekend May 25th!!! Do something to make somebody feel loved today! Then, after observing the positive results, make a good habit out of it!
Scroll down and enjoy the latest comprehensive weather to the max...... occurring because of the natural physical laws in our atmosphere.
Heat ridge in the Southeast(near 100 degree heat far Southeast into early next week) The core of the heat ridge is tenacious but the light is at the end of the forecasting tunnel......not as hot in a week. This is old news now..
Stormy and wet weather ahead. Heaviest rains will be shifting and around the periphery of the heat ridge but there are LESS week 1 rains today than the last few days.
Big pattern change in week 2 as long lived Heat ridge in the Southeast goes bye bye!!!! This will also start to decrease excessive rains! Will the new pattern just be a progressive, west to east but active flow?
Here are the latest hazards across the country.
Purple/Pink/blue on land is cold/Winter weather. Brown is wind, Green is flooding. Gray is fog. Reddish is a red flag advisory.

Current Jet Stream
| Low Temperatures Tomorrow Morning |
High heat in the South/Southeast, some of it surging north! Cool in the N.Plains to west.
Temperature colors on the maps below still need to be adjusted down to cooler shades.
Highs for days 3-7:
Major heat wave in the Southeast. 100 lasting several days. Close to all time May records! Some of that heat expands north early in this period. Cool N.Plains and westward.
This all starts changing late next week! A more zonal, west to east flow with less temperature disparities. Still hot in the Southeast for a bit after that as temperatures there cool down some.
Red very warm anomalies southeast to East(RED HOT temps far Southeast), Chilly blue anomalies N.Plains to Southwest.
Pattern change late next week! The magnitude of temperature anomalies will shrink.

Weather maps for days 3-7 below
Thermal boundary/front continues to act as a focus for waves of heavy thunderstorms.............around the periphery of the intense heat ridge.. Blistering heat in the Southeast. This will be changing.
Heat ridge will expand north briefly early next week ahead of the coming pattern change.
Huge pattern change! Strong, progressive, cold front sweeps southeast in the Midwest, starting midweek............and eventually getting into the Southeast and modifying the intense heat. Reinforcing progressive cold fronts to follow.

Precipitation compared to average for the last 7, 14, 30 and 60 days.
The Cornbelt has had way too much rain. We will be drying out(but not completely dry) for the next several days in some places adding in some heat.
Usually not updated for previous day until late the next day.
https://www.atmos.illinois.edu/~snodgrss/Ag_Wx.html
Soilmoisture anomaly:
These maps sometimes take a day to catch up to incorporate the latest data(the bottom map is only updated once a week).
Some places have dried out enough to plant but its still too wet in other places. Heat in the forecast, especially Eastern Cornbelt will help drying but more rains are on the way. Pattern change later next week to progressive flow.
https://www.cpc.ncep.noaa.gov/products/Soilmst_Monitoring/US/Soilmst/Soilmst.shtml#
Surprise, surprise, surprise!! Currently, there is 0% of the Cornbelt/Midwest with drought. There is no place even slightly dry there. It has been dry(and very warm/hot) in the Southeast though which has some drought. The Southeast drought will continue to expand/get worse during the next week.
The map below is updated on Thursdays.
The market will be keying on precip forecasts for planting concerns for the next month.

The top map is the Canadian ensemble average, the maps below are the individual members that make up the average at the end of week 2.
+++++++++++++++++++++++++++++++++++++++++
Each member is like the parent, Canadian model operational model.......with a slight tweek/variation in parameters. Since we know the equations to represent the physics of the atmosphere in the models are not perfect, its useful to vary some of the equations that are uncertain(can make a difference) to see if it effects the outcome and how.
The average of all these variations(ensembles) often yields a better tool for forecasting. It's always more consistent. The individual operational model, like each individual ensemble member can vary greatly from run to run.........and represent an extreme end of the spectrum at times. The ensemble average of all the members, because it averages the extremes.............from opposite ends of the spectrum.........changes much less from run to run.
End of week 2....................0z ensembles:
Analysis starting from a week ago, ending with today:
Last week+ of analysis, starting with the day farthest in the past. This is an end of week 2 forecast!
Last Wednesday: Vast majority have the heat ridge in the Southeast, with hot/and dry over the Southern 1/3 of the country. Deep trough or upper level low along the West Coast and strong jet stream aimed towards the middle of the country, over the top of the ridge acting to trigger active weather.
Thursday: Around half of the members keep the huge heat ridge going in the Southeast. Half break it down. They will be one of the keys to determine where the strong Pacific jet stream coming in will travel. Potential for a lot of rain when it encounters warm humid air being pumped in by the heat ridge.
Friday: Majority keep the heat ridge going in the Southeast. Very strong jet stream coming from the Pacific.
Saturday: Canadian ensembles shift the Southeast heat ridge farther to the west. Still a strong jet stream across the country, with possibly more zonal, progressive (but active) flow if the blocking heat ridge is displaced from its long lived home in the Southeast.
Sunday: Some solutions keep the long lasting heat ridge in the Southeast alive...........others, obliterate it.
Monday: Watching to see what happens to the heat ridge in the Southeast. ......and location of the powerful jet stream coming out of the Pacific which will be modulated by the upper level trough along the West Coast and downstream upper level ridge.
Tuesday: Same as Monday. In fact, hard to tell any difference in the ensemble average.
Wednesday: Southeast ridge continues to go away/shift west and be replaced by weak troughing in the new pattern. Much, much cooler in the Southeast. Midsection may still be active with a decent jet stream and numerous systems. .
Thursday: Good agreement on a deep upper level low/trough along or just off the West but wide spread downstream on the upper level ridge and path of the strong jet stream in between them.
Friday: Another day with good/strong agreement on the trough around the West Coast. Strong stream from the Pacific will be coming in under this. Where it's aimed downstream will depend on any upper level ridging or no ridging. The long lived Southeast heat ridge still looks to die in week 2(possibly shifting westward to the W.Gulf to N.Mex/S.TX).
Saturday: Still a trough along the West Coast. Strong flow from the Pacific dipping into the trough and being aimed across the US. Will it be a strong, active jet stream coming going west to east in zonal fashion? Or will the flow pattern buckle at some point and become amplified and extreme beyond 2 weeks?
360h GZ 500 forecast valid on Jun 09, 2019 00 UTC
0Z GFS Ensembles at 2 weeks:
Analysis, starting with the oldest, ending with the most recent:
Last Thursday: Heat ridge in the Southeast still pretty impressive with active weather around its perimeter. Will it erode from the north?
Friday: How strong and how long for the tenacious heat ridge in the Southeast?
Saturday: Will the heat ridge move? Will the jet stream migrate north? Is a pattern change coming up? This is possible.
Sunday: Demise of the long lived Southeast heat ridge on the vast majority late week 2.
Monday: Potential shift in upper level ridge position.........MUCH farther north. This may divert the strong Pacific Jet into Canada and help lessen excessive rain potential.
Tuesday: This model also looks like yesterday............and a pattern change coming in week 2.
Wednesday: The heat ridge in the Southeast is completely dead and replaced by troughing and MUCH cooler temperatures. This will lessen the amount of Gulf moisture for active weather systems. Will we have active northwest flow across the belt as an upper level ridge builds in the Plains?
Thursday: Much different than the Canadian model above and tremendous differences/spread for individual members, so great uncertainty. Best agreement is for the upper level ridge in the Southeast to be replaced by weak troughing.
Friday: Pattern change from what we have now with heat ridge in the Southeast broken down but too much spread on how what it will be to take a serious gander.........other than to think that it will be more progressive than the recent pattern.
Saturday: Several members want to greatly deepen an upper level low in SW Canada and possibly buckle the jet stream with an upper level ridge pumped up downstream, which could be any where from the Midwest to points east and south. Just as many have something different.
GFS Ensemble mean(average of all the individual solutions above). The first map is a mid/upper level map. The 2nd one is a temperatures map at around 1 mile above the surface. These are anomalies(difference compared to average). The daily analysis starts with the oldest and ends with the latest.
Last Saturday: The long lived northern stream couplet of positive anomalies in the high latitudes coupled downstream to negative anomalies in Southeast Canada/Northeast US may be getting disrupted. At the very least, the growing positive southern stream anomaly in the middle of the country may deflect northern stream influence to the north. This is a result of a building heat ridge. Still a negative southern stream anomaly in the Southwest (trough of low pressure), coupled with the down stream upper level ridge/positive anomaly, under that right conditions can lead to excessive rains around the periphery of the ridge( especially if it sets up in the Southeast) or could shut down the rains underneath it for much of the Cornbelt if it sets up farther northwest.
Sunday: Long lived northern stream influence looks to be fading and migrating north as a building positive anomaly takes over in the Eastern half of the US and brings heat(except maybe the far Northeast). How the negative anomaly in the west interacts with the upper level high is uncertain with regards to exact location of the large scale features but confidence is high for heat in a large area(dry under the center of the heat ridge) and wet around the periphery.
Monday: Anomalies in the US don't help much, mainly because the contrasting individual solutions offset each other when averaged out. When you have this, you have uncertainty.
Tuesday: Positive anomaly from building heat ridge eastern half of the country.
Wednesday: Still the positive anomaly from the heat ridge in the Southeast part of the country but less pronounced today.
Thursday: Still positive anomaly in the East, negative anomaly in the West. This spells warmth east, chilly west. Wet for much in between(dry Southeast).
Friday; Key negative anomaly in the Southwest which will aim the jet stream downstream. Where it gets aimed will be determined by the location of the heat ridge in the Southeast, where there are still modest positive anomalies.
Saturday: Modest position anomaly shifts west of Southeast, still decent negative anomaly in the West, a bit farther north now and potentially leading to the jet stream shifting north.
Sunday: Positive anomaly shifting to the Plains out of the Southeast. Still the negative anomaly along the West Coast that will be associated with Pacific jet stream energy.
Monday: Growing positive anomaly from Southeast Canada back to the Great Lakes replacing the long lived heat ridge in the Southeast which is shifting on this model. Negative anomaly on the West Coast is getting washed out. Jet stream shifts/weakens.
Tuesday: A weak NEGATIVE anomaly in the far Southeast,tells us the long lived heat ridge will be going bye bye!!!! Now, we have an extensive positive anomaly along the Canadian border in the new pattern...........which will be drier with the heat ridge not steering Gulf air north and blocking progression. Don't see the negative anomaly along the West Coast here but its there on the Canadian model.
Wednesday: Weak NEGATIVE anomaly in the East is even more confirmation that the long lived heat ridge will be dead. Very cool in the East. Positive anomaly in the Plains to West. This is a major pattern change.
Thursday: Very weak negative anomaly very far Southeast/Florida. Positive anomaly Northeast Canada.
Friday: Exactly like Thursday but much uncertainty though it looks progressive.
Saturday: The greatest positive anomalies are at the higher latitudes but most of the US looks to have slightly above 500 mb height anomalies, which means warm temperatures.
NCEP Ensemble t = 360 hour forecast 
Latest, updated graph/forecast for AO and NAO here, including an explanation of how to interpret them.
Previous analysis, with the latest day at the bottom for late week 2 period.
Last Saturday: Still negative AO with the high latitudes not changing a great deal but NAO increases a bit. Mid latitudes could be changing, with potential for more warming from the south in a manner that these indices are not designed to capture well(since they are NORTHERN stream flow indicators). PNA a tad positive.
Sunday: AO and NAO increasing to almost 0 near the end of week 2(after being solidly negative for a couple of weeks)...........suggesting a pattern change that takes out the northern stream influence that has been around for quite some time. PNA near 0.
Monday: AO and NAO increasing. PNA decreasing. Pattern change?
Tuesday: AO and NAO increasing but stay a bit negative. PNA plunging to negative.
Wednesday: AO increases back to near 0. NAO, PNA slightly negative. Nothing strong to key on as indicators.
Thursday: AO, NAO, PNA all slightly negative.
Friday: AO increases to near 0. NAO and PNA slightly negative.
Saturday: The same as yesterday. It's getting to the warm season when these indices are not much help anyway.
Sunday: A0 up to 0, NAO and PNA a bit negative.
Monday: All slightly negative. Could have a pattern change later in week(not because of these indices though)
Tuesday: AO, NAO, PNA all a tad negative. Nothing to see here.
Wednesday: A tad negative. The PNA has a wide spread at the end of week 2, some strongly negative.
Thursday. Slight negative for NAO/AO, near 0 PNA.
Friday. Slight negative for NAO/AO and near 0 PNA again.
Saturday: Same. Suggests zonal flow.
National Weather Service 6-10 day, 8-14 day outlooks.
Latest morning thoughts, starting with the oldest down to the newest:
Last Saturday: Could be seeing some shifts after today in these outlooks (8-14 day) but probably not this afternoon yet.
Sunday: Should start seeing these outlooks cool down(less heat) the Southeast, starting with the 8-14 day.
Monday: Still looking for the pattern change starting to show up in these 8-14 day outlooks pretty soon.
Tuesday: Confidence still that the heat ridge will be fizzling out in the Southeast with intense heat there going away. Temperatures and precip reconfigures across the country with much less extreme weather! This will start showing up with gusto in the 8-14 day maps...................finally??
Wednesday: With incredibly high confidence, the NWS will finally start cooling off the Southeast, especially in the later/8-14 day period. Rains will continue above for the Cornbelt, however.
Thursday: The NWS has been slow to reflect the cooling in the Southeast that I(and the ng market) think is coming in the late part of week 2 but we will call for them to see it again today. Still wet but not as extreme in the later periods.
Friday: Still surprised the NWS has not cut back on heat probabilities in the Southeast the last few days with the pattern change. Rains should continue above on the outlooks but more progressive, less excessive type rain events with the new pattern.
Saturday: Heat probabilites are finally getting reduced a bit in the Southeast(not nearly as much as I think/though). More of the same with the country, looking pretty warm in most places. Rains still above average too.

The GFS and Euro suites have been consistent on predicting near all-time record May hottest for much of the SE US on several days late next week into early the following week of upper 90s to low 100s! Drought areas there will likely expand and get more intense.

The NWS service in Indy reported .22 with that one along with the .19 earlier in the day.
Hopefully that will be it for a couple of days.
When this front comes back as a warm front, most of the rains will be to the west but its possible they could be in Indiana.........just impossible to know.
If we can get that warm front shoved to the Michigan border, you would be in some heat and dry weather later this week. This heat ridge is definitively going to expand north later this week though into the ECB, high confidence. Thursday and Friday, I wouldn't be surprised to see 90 for you mcfarm, along with a pretty decent sw wind, especially Friday.
+++++++++++++++++++++++++++++
By metmike - May 20, 2019, 1:47 p.m.
Heat ridge will be shifting out of the Southeast in week 2, probably.
Looks likely that it will be shifting west and maybe building up thru the Plains...............but maybe not dry.
The jet stream track around the ridge may cause a "ring of fire" pattern that features clusters of storms that MOVE(not a blocking pattern, from the Plains into the Midwest with much more heat, farther north and west.
This won't show up yet on the NWS guidance today.......maybe the 8-14 it will.
The Southeast WILL be cooling off noticeably in the 8-14. starting soon.
Still a ton of rain before the new pattern shapes up and the new pattern is not necessarily a dry one, especially with these wet soils in early June. The high angled sun will evaporate alot of moisture from the surface to boost rainfall amounts.
However, since this new pattern will feature much LESS rain, if planting progress is better than expected and it continues to look drier, last nights gap higher in corn could be an exhaustion gap. Not my prediction with so much rain on the way but the heavy rains are stale news and we are almost 50c higher.

Thanks mcfarm,
Sorry you're having a rough time of it. I'll have all the stats in a short while. This(less planted c/s) will cause us to have a higher open tonight.

12z GFS was WETTER!
For the 3rd run in a row, it brings an almost unprecedented, for the end of May polar vortex low down to just north or the Great Lakes early in week 2. For now, its at such an extreme that makes one skeptical.
For the last 3 runs, the GFS has been forecasting an unprecedented deep polar vortex low dropping south to just north of the US border early in week 2.
This is the now updated 12z GFS run for May 30.
This is an outlier and such an extreme that means it can't be believed. There would be alot of clouds with it that might keep night temps above freezing. Also, nights are very short, so less cooling time and surface temperatures even at the highest latitudes have warmed enough so its almost impossible to bring enough cold air, moderating on the way down, deeply into the US to cause a widespread freeze in the Cornbelt.
But if it can happen, the pattern below would be favorable.

Sorry to hear your having such bad luck mcfarm,
We've really dried out everywhere here in S.Indiana, I hope we can send some of it your way along with some heat and wind the next couple of days.
Unfortunately, the front between the hot air down here and cooler air farther to the north and some jet stream energy is going to be close enough to you so that more shwrs could happen at any time. Hopefully the heat ridge ends up stronger and shoves it farther north.
I know it sounds crazy but your NWS actually is a tad below average for May rainfall on their climate report

Mike,
Whats your guesstimate for number or % of corn acres pp or drowned to date? Are we now presumed to be below trendline yields?
++++++++++++++++++++++++++++++++++++++
Re: Re: Re: Re: Re: Re: Re: Re: Weather Friday
By metmike - May 25, 2019, 1:43 a.m.
Wonderful question becker!
I'll try to answer that in more detail and would appreciate others thoughts on that too tomorrow.
I know that some are insisting trendline yields are impossible now and I would agree that they are unlikely but they ARE possible. The increase in CO2 has been boosting yields tremendously and we have added a tad more beneficial CO2 since last year. No matter how bad everything else is and gets, that is still going to be a huge plus that's been adding something like 15% to corn yields and 25% to bean yields vs what they would be if CO2 had not gone up.
If we dried out the next 2 weeks, then had perfect weather the rest of the growing season, we can certainly have trendline yields. It will be on reduced acres of course, so that is going to cause lower production.
More later.
What are your thoughts?
+++++++++++++++++++++
Re: Re: Re: Re: Re: Re: Re: Re: Re: Weather Friday
By mcfarm - May 25, 2019, 7:04 a.m.
sure good yields are possible. In 1981 we did not plant a seed until June 1st and the summer proceeded to be warm and wet. Stuff grew a foot a wee it seemed. Very unusual.

By cliff-e - May 25, 2019, 12:20 p.m.
I talked with a farmer last night who planted/mudded in corn 2 weeks ago...it has a sprout but due severely compacted soil and our cold overnight temps. the corn sprout has made a 90 degree turn and is trying to leaf out under the ground. We have rain forecast again for Sunday night into Monday...maybe an 1" but when we have water running out of hillsides due to our already high water table even .2" makes it look like we had 2".
++++++++++++
here comes big rain event number 1 of the day from the SW like a freight train
Here's hoping that you are in between the scattered heavy cells.
Continuing on the yield discussion. The graphs below tell us that this is THE latest planted year and how crops did in previously late planted years.
The bottom line is that the weather still will be the main player and is completely unknown.
However, we can say with high confidence that a record, well above trend yield is almost impossible but who doesn't know that.
2009 was a late planted year(mainly IL) but featured a cool, wettish Summer and the corn crop actually was close to record yields. Beans were around average. Producers remember 2009. The cool Summer featured very low heat units and the crop in late August, we more like early August maturity.........it would have been hurt bad by an early freeze.
Luckily, September was warmer than normal and the first freeze was late everywhere, allowing the crop to mature. Heat units accumulate slowly at that time of year but we got enough of them. However, after the crop matured a few weeks late, it was time for it to dry down in the field and we just ran out of time on the calendar to do this. It was also pretty wet in October so there wasn't much drying going on. Moisture levels were already unusually high and that crop was harvested the wettest and maybe the latest ever. The IA corn was coming out of the field at moisture levels of 22%+, 14% is pretty good. . The ND crop was only 8% harvested in mid November! LP gas/ng demand/use to dry the crop down was a record for a couple of months after that.

What is striking to me, is the strong correlation to beans with planting date. Outside of the 1 drought year of the last 30 years, 2012) almost all the low bean yields were in late planted years. Why might this be?
Corn develops/matures based on heat units and in late planted years, we assume it was too wet and the soil profile was saturated. Corn can establish deep roots to tap deep moisture. Beans can't do this and beans have their key developmental period later in Summer.
So if it turns hot and dry, it can hurt beans more than corn. Also beans develop based on daylight hours. If you plant them late, they can't catch up with heat because the length of day never changes, its based on the calendar. A late start, means beans can't cash in on some of the longer days in May/early June ahead of the Summer Solstice and are still hanging around, not mature yet, in September, over 2 months after the sun strength has peaked and they are catching, lower angled weaker sunshine that also contributes less energy to photosynthesis(which can be said to about corn but to a much lesser degree-May sunshine is stronger-has more energy, because of the higher angle- than August sunshine for instance-regardless of temperature)
We had some rain over nite but dried up enouh to plant by noon in wet soil
Heat and wind acrually had dust on the lighter soils by 3 P:M
By 5 P;M we had a gully washer
I don't even want to look at the rain gauge
Thanks for the report Wayne
