.DISCUSSION...
Issued at 218 AM CST Tue Feb 3 2026

Water vapor imagery shows a shortwave trough moving into far
northwestern MO as of 08Z Tuesday. Models show some saturation
increasing and deepening this morning to potentially a 5000 ft thick
cloud deck. But ascent through this saturated layer is weak at
best. Given the weak ascent and relatively shallow saturated
layer, it seems that at best we get a few flurries across
northwestern MO and northeastern KS this morning. Any chances
decrease quickly with the passage of the shortwave and resulting
shift to stronger descent. Temperatures look to be 5-10 degrees
cooler today compared to Monday, with light northerly flow
ushering in cooler air behind a weak cold front. That cooler
air lingers over the region Wednesday as broad upper troughing
and cyclonic flow prevail.

A warming trend commences late in the week as the upper-level high
portion of the Rex block over the western US shifts eastward. This
ridging builds east through the later half of the week and as a
result we should see highs climb from the 30s and lower 40s on
Wednesday, to the middle 40s and middle 50s on Thursday -
Saturday. Our southwestern zones may push for 60 degree
temperatures Friday and Saturday as well. In fact, the
southwestern half of the forecast area, from roughly Sedalia to
St. Joseph, has at least 10% to as much as 50% chance for
seeing 60 degree highs on Friday with a 25- 55% chance on
Saturday. A shortwave trough may knock temperatures down a few
degrees on Sunday, but the ridge builds back Monday with similar
probabilities for 60 degree highs to Saturday. Late in the
forecast, our next chance for precipitation arrives as strong
moisture transport northward into the area commences ahead of
the next shortwave trough.
