- No significant weather impacts expected for the next 7 days.

.NEAR TERM...
(Tonight)
Issued at 228 PM CST Mon Dec 22 2025
Not much change from the morning update, as overcast skies abound
with low clouds streaming northward across the CWFA. Dewpoints are
slowly climbing across the area, with the middle/upper teens in
far NE AL upwards of the lower 40s across NW AL. Morning lows will
bottom out in the lower/middle 40s SE, lower/middle 50s NW. The
forecast is in great shape and no other updates are needed at this
time.
&&
.SHORT TERM...
(Tuesday through Thursday)
Issued at 1010 AM CST Mon Dec 22 2025
Tuesday will nearly be a rinse-and-repeat forecast, with the low
chances (15-25%) for NW AL and portions of Southern Middle TN.
Cloudy conditions will prevail once again, with most areas
remaining dry. Southwesterly flow will increase through the day,
which will lend to warmer high temps tomorrow topping out in the
middle 60s/lower 70s.
&&
.LONG TERM...
(Wednesday night through Sunday)
Issued at 1005 PM CST Sun Dec 21 2025
Lows will remain in the lower to mid 50s Tuesday night with some
early cloud cover lingering. Even warmer conditions are expected on
Christmas Day, as upper level ridging remains over the Gulf Coast
states into northern Alabama. Highs by Christmas Day will likely
be in the lower to mid 70s, despite some clouds at times.
Another frontal boundary moves through the area on Friday. A few
models do show some very light rain with it, but not much.
Increased cloud cover and some weak cold air advection will drop
highs a tad into the mid 60s to lower 70s on Friday. However
temperatures quickly warm behind it into the 70 to 75 degree range
on on Saturday.

.AVIATION...
(18Z TAFS)

20kts, with MVFR/VFR conds prevailing.
