.DISCUSSION...
Issued at 248 PM CST Mon Jan 19 2026

High pressure was in control across the Central Plains into the
Mid-Mississippi Valley this afternoon with mainly clear skies
over the Lower Missouri Valley region. Winds were diminishing
across the area as the high continued to build in. Heading into
tonight, temperatures will fall into the teens and single digits
above zero, but for the most part will not be as cold as last
night. Winds will be very light, so any wind chills should
remain above zero.

Fairly benign conditions will prevail for the middle of the
week as temperatures trend near to above normal. Wednesday will
be the warmest day with highs in the upper 30s to upper 40s
before cooling back to near normal levels for Thursday in the
wake of a cold front. A trough will move through the region for
Tuesday into Wednesday, but this looks to be a dry frontal
passage with any precipitation remaining to our north and south.

The jet moves overhead for Friday into the weekend as cold high
pressure becomes established across the Upper Midwest. Models
continue to advertise a large baroclinic zone extending from the
Southern Plains into the Deep South during this time period with
an expansive area of QPF in the vicinity of this zone as well.
Exact placement remains in question, but there remains a chance
that some of that QPF may reach into the CWA. Given the
reinforcing shot of Arctic air expected Friday, anything that
does fall will be in the form of snow. We may just as well
remain enough to the north of this system to remain dry as well.
A stronger area of high pressure to our north may suppress this
activity to our south. Additionally, there isn`t much for
midlevel forcing in the area and we may remain moisture starved
as well. So while there is a chance for snow late in the period,
it doesn`t look overly significant at this time.
