.DISCUSSION...
Issued at 1250 AM CST Thu Dec 11 2025

Today and Tonight...A weak frontal boundary moved across the area
on Wednesday and this resulted in a brief cooldown. Surface high
pressure is centered over the area this morning and this will
shift east of the area this afternoon. The flow will become
southerly this afternoon, with temperatures mostly in the mid to
upper 50s. Mostly clear skies will prevail through much of the
night tonight, with some increase in clouds by morning. Lows will
range from the upper 30s to low 40s. /15/

There will be a brief but significant warm-up Friday/Saturday
in the return flow ahead of stronger cold front approaching from
the north. A quick round of showers will accompany the front and
bring light rainfall (less than a quarter of an inch on average),
then much chillier temperatures will follow the frontal passage as
we go from late Saturday night into early next week. Forecast
confidence for this round of colder temperatures continues to
increase, and the intensity of the cold forecast has increased
just a bit more as more guidance points to a significant polar
high surging south through the MS Valley.

The cold anomalies should be centered on Monday morning when lows
could dip into the upper teens north of the Highway 82 corridor,
but dangerous levels of cold are not expected for the most part
and the coldest air will only make a brief visit. Look for
temperatures to rebound and rainfall chances increase a bit as we
go into mid next week. /EC/
