.NEAR TERM...
(Rest of tonight and Friday)
Issued at 1047 PM CST Thu Dec 4 2025

The strongest forcing has pushed east into Georgia over the last
few hours. Light to moderate rainfall still lingers behind this
shield of precipitation. Thus, expect a mixture of light rain and
drizzle to linger in far NE ALabama until around daybreak before
ending. Not expecting alot more rainfall, but another 1/10 of an
inch or so could occur before ending.

Some patchy fog could occur right around daybreak. However,
mainly expect a cloudy and cold day. Highs with cloud cover and
initial weak cold air advection this morning should only reach the
40 to 45 degree range (coolest temperatures near the AL/TN border
and in portions of southern middle Tennessee).

.SHORT TERM...
(Friday night through Sunday)
Issued at 1047 PM CST Thu Dec 4 2025

Tonight will likely be a better setup for more at least patchy fog
development across northern Alabama and southern middle Tennessee.
As winds decouple with a surface high building over the area,
winds will be very light. Luckily, most guidance still holds
mostly cloudy to cloudy conditions in place though. This should
mitigate the fog threat some. Wouldn`t be surprised to see some
patchy dense fog, but widespread fog (especially dense) may be
hard to get with such predominant cloud cover. For now included
patchy/areas of fog, but no dense fog. This may need to be
changed if forecast conditions warrant. Most areas should not see
temperatures dropping to 32 degrees or below. However, a few
locations in NW Alabama and southern middle Tennessee may around
daybreak on Saturday, so a bit of freezing fog could be possible.
Lows in the lower to mid 30s are expected.

Zonal flow and neutral to weak warm air advection mainly sets up
Saturday through Sunday. We may finally see some sunshine again
during the afternoon hours on Saturday. This insolation and weak
warm air advection should allow high temperatures to climb back
into the 45 to 50 degree range mainly.

By Saturday night, another longwave trough axis begins to swing
southeast from the western Great Lakes area towards the Ohio
Valley. This will likely bring some cloud cover back into the
area in the evening hours and mostly cloudy conditions back into
the area by daybreak on Sunday. Stronger forcing and better
moisture advection pools over the area on Sunday. Lows don`t look
to change much and should stay in the lower to mid 30s.

.LONG TERM...
(Sunday night through Thursday)
Issued at 1047 PM CST Thu Dec 4 2025

As this longwave trough axis pushes east and an attendant cold
front pushes into the area, some light showers will likely return
to the forecast. Expect the better chances of rain will be
mainly Sunday night into early Monday morning as longwave trough
axis moves through northern Alabama and southern middle Tennessee.
This should usher in some cooler air again early next week after
its associated cold front moves east of the area.

.AVIATION...
(00Z TAFS)
Issued at 610 PM CST Thu Dec 4 2025

MVFR VSBYS and RA are expected to continue at both terminals
through 1Z or 2Z. This will change little, but expect CIGS to
lower below 1000 feet around 7Z at KMSL and 9Z at KHSV and RA to
likely stop at both terminals. Expect low clouds to stick around
with MVFR VSBYS. May have to lower VSBYS or CIGS a bit more with
next issuance around daybreak. After 15Z, expect CIGS to climb
back above 1000 feet and fairly light winds to continue.
