.SHORT TERM...
(This evening through Wednesday)
Issued at 155 PM CST Tue Dec 5 2023

Quiet weather will continue across our area in the short term. A
weak cold front is draped across the I-20 corridor this afternoon,
with slightly cooler temperatures across the northern Big Country.
The front will wash out overnight with light winds and mostly
clear skies. Lows will again drop off into the 30s but look to
remain above freezing for most locations. Winds will switch back
around to the south on Wednesday with mostly sunny skies and mild
temperatures in the mid to upper 60s.

.LONG TERM...
(Wednesday night through next Tuesday)
Issued at 147 PM CST Tue Dec 5 2023

...Warming trend through the end of the work week. Strong but dry
cold front moves through Saturday, bringing near normal temperatures
back through early next week...

Shortwave ridging will be overhead Thursday ahead of the next
upper level trough moving onto the Pacific Coast. Clouds will
clear through the day as surface winds out of the southwest begin
to pick up due to pressure falls in the Colorado Rockies starting
to tighten the local pressure gradient. This will help to usher in
a much warmer and more tropical airmass into the area with dew
points increasing back into the 50s and highs back into the upper
60s to mid 70s. This trend will continue into Friday where
temperatures will be ~10-15 degrees above normal in the mid 70s to
lower 80s. Southwest winds will increase some more into Friday
with continued pressure falls and southwest flow through the
profile becoming more aligned, allowing for deeper mixing during
the day.

The aforementioned upper trough is expected to swing through the
Desert Southwest and Southern Rockies late Thursday into Friday
before moving into the West Texas region early Saturday. A
corresponding surface low will drop southwest out of the Colorado
Rockies and into the Red River region overnight Friday into
Saturday. A cold front is expected to follow suite and move through
the area with abundant cold air advection and strong northwesterly
winds behind it thanks to a strong pressure gradient with a deep
surface high in the Intermountain West. High temperatures Saturday
will be 15-20 degrees below where they were on Friday in the mid 50s
to low 60s. The frontal passage is expected to remain dry for our
area with the better chances for precipitation well off to our north
and east. Though the cold air advection will largely shut off by
Sunday morning as surface winds weaken and back to the southwest
once again, temperatures will remain fairly stagnant through the
early portions of next week. The upper level pattern will become
largely zonal across the southern plains, keeping impactful
weather out of the area through mid-next week.
