.LONG TERM...
(Monday through Saturday)
Issued at 1212 AM CST Sun Dec 7 2025

A dry forecast is in store for this week, and our area will be under
northwest flow aloft. A series of upper troughs will move southeast
from the northern Plains across the Great Lakes and Ohio Valley. A
weak cold frontal passage is progged for Wednesday, with a stronger
cold front Thursday afternoon and evening.

After a cold start to the day Monday, afternoon highs are expected
to be in the upper 50s to mid 60s with mostly sunny skies and a
return of southeast to south winds.

Warmer and above normal temperatures will occur on Tuesday and
Wednesday with mostly clear skies. Increased/breezy south-southwest
winds are expected Tuesday with a tightening pressure gradient and
lee surface trough development to our west. A weak cold frontal
passage is progged Wednesday afternoon and evening, but will
essentially just result in a temporary wind shift. Highs Wednesday
are currently forecast to be in the upper 60s north to mid 70s
south.

A stronger cold front is forecast to move south across our area
Thursday afternoon and evening. Recent model trends are stronger
with this front. Timing of this frontal passage will be key to how
warm temperatures get on Thursday (prior to its passage). At this
time, blended model solution has highs ranging from the upper 60s in
the northern Big Country, to around 80 along the I-10 corridor.
Following passage of this front, gusty north-northeast winds are
expected Thursday night and Friday, as a strong surface high
pressure ridge builds south across the Great Plains from southern
Canada. Blended model approach has temperatures much cooler Friday
and Saturday. Current forecast highs Friday are from near 50 north
to the upper 50s south, and lows Friday night in the mid 20s to near
30. Highs on Saturday are mostly in the 50-55 degree range. However,
stronger cold air advection could result in temperatures being
colder than what is currently forecast. Will continue to monitor
model trends and the possible need to adjust temperatures lower.
