Welcome April 5th! Do something to make somebody happy today. Don't just think about it........do it. Then think about it.............and how you just made somebody's world a tiny bit greener.
Our local chess tournament last month got some great coverage. I'm extraordinarily proud of the kids and also the adults that helped run this event:
Scroll down and enjoy the latest comprehensive weather to the max. Here's the latest weather..... occurring because of the natural physical laws in our atmosphere. Still looks too wet for early planting....not quite as wet today.
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.

IT's BEEN DRYING OUT IN THE SOUTH BUT IT WILL GET WET AGAIN THERE!
Usually not updated for previous day until late the next day.
VERY wet but its been drying out in the south.................with lots of rain coming up in the next 2 weeks.
Currently, there is 0% of the Cornbelt/Midwest with drought. There is no place even slightly dry there.
The South has been really drying out recently but heavy rains coming up should wipe out some of the dryness in much of that area.
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
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 from FRIDAY:
Analysis starting from a week ago, ending with today:
Last week+ of analysis, starting with the day farthest in the past:
Last Monday: It's all southern stream, Energy from the El Nino driven active south Pacific wil be aimed towards the central and souther US. The question is NOT will it be wet with this pattern but HOW WET and HOW FAR north and west will the wet pattern be? The N.Plains and far Upper Midwest will not be as wet.
Tuesday: Similar to yesterday. The mean looks zonal and for sure dials out any northern stream influence, so temperatures should be mild. The individual solutions still show a lot of potential southern stream activity and precipitation but are not quite as wet today.
Wednesday: Potential for heavy precip and possible excessive rain event(s) from the El Nino driven southern stream late week 2.
Thursday: I still see the threat of heavy rains. The more amplified the ridge in the east becomes, the heavier the rains.
Friday: Watching the southern stream for the potential of excessive rain events. Upper level ridge in the Southeast and upper level trough in the West are ideal set up.
Saturday: Setting up for the excessive rain events in week 2 from S.Plains to points east/northeast.
Sunday: Not sure on where the wettest weather will be now but still leaning to S.Plains for heaviest. . Looks active but more progressive.
Monday: Still wet as we go into mid April. Will the upper level ridge in the Southeast be strong enough to keep the flow from being progressive? Any amplification of the ridge or upper level lows/troughs in the southern stream will result in some excessive rains.
Tuesday: Very wet from the southern stream. Looking at the potential for excessive rain events in the S.Plains and points east/northeast again.....depending on how stout the ridge in the Southeast is.
Wednesday: Much drier for this ensemble model and run at the 2 week time frame. Also cooler in the Midwest/East. Will ridge West/trough East couplet in Canada to Upper Midwest take over and suppress the southern stream?
Thursday: Yesterday, the Canadian ensembles were the only model to look much drier. Today, they are much wetter and back to the old solution, so yesterday was a fluke. In fact, they and all the other models are the wettest yet for week 2 of any forecasts going back some time. Potent southern stream and cut off low potential with excessive rains from the S.Plains to point east/northeast. Still several members that like yesterdays colder and drier solution(especially Upper Midwest) with a stronger northern stream.
Friday: The mean looks more zonal today for both the southern and northern stream. This results in milder temperatures in the north and less precip most places, especially with the less amplified southern stream.
360h GZ 500 forecast valid on Apr 20, 2019 00 UTC
0Z GFS Ensembles at 2 weeks:
Analysis, starting with a week ago:
Last Monday: Active southern stream, high confidence............ for this far out at least.
Tuesday: Some solutions are looking drier.
Wednesday: Southern stream looking especially active late week 2 on this mornings solutions. Deep trough to cut off low in the S.Plains.
Thursday: This particular batch of solutions does not look as wet as the 0z Canadian model ensembles to me but the run after this, 06z GFS ensembles looked wetter.
Friday: Still looking very wet. Widespread and in some places potentially excessive rains.
Saturday: Active Southern stream. Heaviest rains, possible flooding from S.Plains east/northeastward.
Sunday: Active and wet with southern stream dominant.
Monday: Wettest weather in the S.Plains.
Tuesday: Wettest weather in the S.Plains but now with the potential of an upper level low in the Northeast, a possible northern stream and cooler temperatures in mid April.
Wednesday: Southern stream looks more active on this model vs the Canadian , especially the 6z run after this one below.
Thursday: GFS ensembles continue VERY wet from a powerful southern stream. Southern Plains to points east/northeast have the highest potential for excessive rains.
Friday: This model still has a pretty potent southern stream and deep upper level trough on many solutions.......favored towards the west.
Ensemble mean(average of all the individual solutions above)
Last Monday: Positive height anomaly in the Great Lakes means mild weather. Extension of that westward....possibly protecting that area from the wet southern stream which will define the (WET) weather over much of the US.
Tuesday: One noteworthy and potentially huge change. The negative anomaly in the West has been shifting farther west............now out in the East Pacific and growing. This could be so far west that it induces downstream ridging farther west and shifts the storm track far enough west so that the Gulf of Mexico is not wide open all the time. This is why my extended range forecast is a bit drier today, taking this into account.
Wednesday: Similar anomalies to yesterday but my analysis, suggesting a potential to turn drier may be flawed. This, because of the new negative anomaly in the S.Plains, induced by energy eminating from an El Nino drive southern stream. This, in combo with the positive anomaly in the Northeast, spells very wet weather for the S.Plains and points northeastward. Potential for excessive rains(more favored in southern locals at this time) with the Gulf of Mexico wide open.
Thursday: A growing new positive anomaly in N/C Canada on this run. Will it mean anything with regards to the northern stream down the road? Southern stream and heavy rain threats are still the main show for the US, especially around the S.Plains and points east.
Friday: Still positive anomalies in the East/Northeast and today's southern stream negative anomaly center in the far Southwest.......favorable for moisture to gush north from the Gulf of Mexico and southern stream energy from the tropics/El Nino to be aimed in that direction.
Saturday: Big change in the positive anomaly centers. The one in the Northeast weakens with a new, greater one from central to Northeast Canada associated with the northern stream that "could" turn things chilly in mid April if it were to strengthen..........speculative. Not much speculating on the southern stream being strong. Just a matter of where its going to be aimed for heavy precip.
Sunday: Active southern stream. Where will it be aimed?
Monday: Anomalies not that impressive.
Tuesday: Anomalies changing quite a bit. A new positive one in Northwest Canada across Alaska(another around Greenland) with the positive anomaly in the Northeast that was the main one last week, being replaced with a negative anomaly in Southeast Canada. This suggests the increasing potential for chilly weather in mid April. It could also dry things out in the Midwest by suppressing the southern stream farther south, into the S.Plains.
Wednesday: New anomaly centers continue from yesterday. Positive Northwest Canada to Alaska, negative downstream to the southeast. Should mean cooler mid April weather. Will it also dry things out in the Upper Midwest/N.Plains and suppress the southern stream south? Watch the upper level ridge in the Southeast. If it holds, it will be very wet in the S.Plains.
Thursday: Anomalies in the high latitudes, N.Alaska across the N.Pole to NE.Canada and negative anomolies in the S.Plains increase chances for cold in Canada to travel south but the big story is going to be southern stream energy.........and where its aimed. This will be defined by the negative anomaly in the vicinity of the S.Plains and positive anomaly in the far Southeast(which pumps up the moisture and blocks the progression of the large scale upper level low to its west). How wet it gets will be influenced by how amplied these features are.
Friday: High latitude positive anomaly is undercut by Pacific flow/disconnected from a downstream negative anomaly which would establish a couplet for moving cold air south. Still a negative anomaly in the Southern Plains and vicinity associated with the Southern Stream.
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 Monday: AO drops hard at the end of 2 weeks from positive. NAO stays solidly positive.......making it tough for cold to penetrate deeply into the US and being favorable for wet weather. PNA is barely positive at the end of 2 weeks.
Tuesday: AO drops hard to slightly negative. NAO and PNA are positive at the end of 2 weeks. It's the time of year when these indices are not as powerful as indicators for temperature trends in the US compared to a couple of months ago. However, the NAO/PNA can sometimes suggest a pattern that helps with precip. If we get a strongly negative NAO for instance, it often suppresses Gulf of Mexico moisture from maintaining a constant presence in the Midwest.
Wednesday: AO plunges to negative with very wide spread. NAO is mostly positive but not entirely with wide spread. PNA stays slightly positive with wide spread. Looks like potential for big changes and possibly a lot of action as we get into the 2nd week of April!!!
Thursday: AO drops to a bit negative. NAO drops to a tad positive from strong positive. PNA increases a great deal into positive territory late in the period. If this were January, one might be watching for a change to colder.
Friday: AO drops to negative, NAO to slightly negative, PNA to around 0. Not favorable for any cold.........but its April now people!
Saturday: AO really plunges now, to moderately negative. NAO to around 0 from positive and PNA a bit positive. Keep this up with gusto and the mid April forecast might turn cooler but we're a long ways from that and they indices are not as powerful for northern stream insight/affect on the US in the warmer months.
Sunday: AO drops to negative, not as much as yesterday..............less cold threat. NAO has a very wide spread on both sides of 0. PNA slightly positive.
Monday: AO a bit negative. NAO drops to near 0. PNA a tad positive. Weak.
Tuesday: Stronger signals today. AO more negative......and favorable for cold air to be flushed from high latitudes, towards the mid latitudes. NAO now negative........more favorable for penetrating of cold into the Midwest/Northeast. PNA is slightly positive and increasing which also assists with those indices in increasing some chilly risks in mid April and beyond.
Wednesday: AO goes negative much sooner and in week 1, then drifts to less negative at the end of 2 weeks. NAO spikes to negative then recovers to less negative at the end of week 2. PNA slightly positive. Turning cooler next week.
Thursday: AO plunges to VERY low values next week with the NAO also diving much lower into negative territory. This, in tandem with much cooler forecasts as air from higher latitudes makes its way into middle latitudes. These indices bounce a bit at the end of 2 weeks. If this were January, it would be pretty bullish for ng. The PNA is a tad positive.
Friday: Negative AO bounces up towards zero near the end of 2 weeks, just like the NAO. PNA is a tad positive.
The link below, now has the PNA index added at the bottom:
Spring outlook from the NWS.
This is a HUGE deal to the grains, especially corn because planting, ideally can get going by the end of April and needs to be done in May.
Many traders/forecasters are drawing similarities to 1993 and the historic flooding of that year because that was the last time conditions were like this.
Each year is different. One thing is certain. The market will NOT be concerned about drought during planting and the early parts of the growing season. Surface and subsoil moisture is completely recharged almost everywhere.
It is getting quite dry in much of the SE US. So, rain is needed. Upcoming warmth will exacerbate the problem.
I've noted how dry that its been recently in the South and it's too dry now in a growing area(I just updated the drought monitor map above).
The pattern coming up could take care of that quickly if the zone of heavy rains is far enough east.
Excessive rain risk for the week 2 period below. Note the HIGH risk area for the first time by the NWS.
Late April into early May guess-cast (-:
IFF this would verify, it would be bearish corn..
Above temps to warm up soils nicely and as long as rains are not above average, things will dry out enough to get the crop planted in timely fashion.
Cold would be bullish as well as above precip............and there is plenty of that in the next 2 weeks but it doesn't really count as much until the end of the month, if it still looks cold/wet.
