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.
https://www.atmos.illinois.edu/~snodgrss/Ag_Wx.html
Soilmoisture anomaly:
VERY wet but its been drying out(too much in the south).................with lots of precip coming up in some places but not as wet today in the 2 week forecast for some places compared to last week.
https://www.cpc.ncep.noaa.gov/products/Soilmst_Monitoring/US/Soilmst/Soilmst.shtml#
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 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 MONDAY:
Analysis starting from a week ago, ending with today:
Last week+ of analysis, starting with the day farthest in the past:
Last 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.
Saturday: Less zonal but the upper level low/trough from the southern stream on numerous solutions, backs up so far west that it results in a warmer and especially drier Midwest.
Sunday: Wide disparity on solutions, howeverer: 1. The mean is much more zonal and drier than the previous one and most of them last week! 2. Temperatures will be mild unless the northern stream amplifies and/or look like a minority of solutions show.
Monday: The mean/average is zonal but many solutions don't look like the average, they have an amplification of the pattern somewhere(possibly just transient). Majority are not nearly as wet as last week. No major cold intrustions.
360h GZ 500 forecast valid on Apr 23, 2019 00 UTC
0Z GFS Ensembles at 2 weeks:
Analysis, starting with a week ago:
Last 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.
Saturday: Not as wet with less upper level ridging in the Southeast.
Sunday: Not as wet again, with regards to the threat of excessive rain events, without much ridging in the Southeast. However, It still could be quite wet in some places and very active.
Monday: Still not nearly as wet as last week with several solutions taking the southern stream out as a major factor.
Ensemble mean(average of all the individual solutions above)
Last 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.
Saturday: Southern stream negative anomaly shifting west of Plains, slight positive anomaly in the Midwest suggests potentially much drier....and warmer.
Sunday: No big anomaly centers to key off of. Slightly positive in the east and negative in the Plains still suggests at least some rain.
Monday: Weak anomalies from the mean, much because the disagreements average out.
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: 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.
Saturday: Negative AO and NAO with chilly weather late week 1/early week 2, then they recover towards zero and temperatures warm. PNA.close to 0.
Sunday: AO, NAO and PNA all close to 0 in 2 weeks.
Monday: AO and PNA near 0, NAO slightly negative.......not major factors.

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.

Larry,
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.

metmike, big talk of a 12 to 16 inch snow fall coming to the upper midwest......are you predicting th same?

By metmike - April 8, 2019, 11:16 a.m.
Yes mcfarm!
Looks like SD to MN will have the heaviest snow. Thanks much for pointing this out.
