.NEAR TERM...
(Tonight)
Issued at 155 PM CST Sat Dec 6 2025

The low stratus cloud deck that blanketed the region this morning
has been gradually eroding this afternoon. Skies should be mostly
clear by late this afternoon; but, this only gives a few more
hours of heating. Current temperatures are in the lower to mid 40s
and likely will warm perhaps 5 degrees or so at most during that
time. Therefore, forecast highs in the mid to upper 40s for most
locations seem reasonable at this point. A few locations may get
close to or reach 50 degrees, especially over northwest Alabama.

Forecast thinking for tonight has not changed since the previous
update. There is a low to medium chance (20-40%) of fog
development this evening and overnight. Some of this may actually
be freezing fog over northeast Alabama and into southern middle
Tennessee as temperatures drop to freezing or just below late
tonight into early Sunday morning. Overall, expect lows in the
lower to mid 30s. As clouds increase once again late tonight into
Sunday and as the sun rises, any fog will then dissipate.

.SHORT TERM...
(Sunday through Monday)
Issued at 938 AM CST Sat Dec 6 2025

The base of the aforementioned upper trough will amplify just a
bit and swing over the Southeast through Monday. Additionally, a
surface cold front will traverse the region Sunday night as well,
with high pressure pushing into the region from the west by Monday
afternoon. With this front will come low to medium chances
(20-40%) of rain for all of north Alabama and southern middle
Tennessee. Thunderstorms are not anticipated with this activity
due to the lack of any instability. As the front pushes to the
southeast early Monday morning, rain chances will taper off. Dry
conditions will then return for the afternoon.

A bit warmer temperatures are expected on Sunday and Sunday
night, but not by too much. Highs Sunday are forecast to only
reach the lower 50s due to cloud cover, with mid 30s to around 40
degree lows Sunday night. Behind the cold front will come colder
air due to cold air advection from the northwest. Highs on Monday
are expected to merely top out in the lower to mid 40s. Some areas
in the higher terrain of northeast Alabama and southern middle
Tennessee may see cooler highs, in the upper 30s to around 40
degrees.

.LONG TERM...
(Monday night through Friday)
Issued at 1105 PM CST Fri Dec 5 2025

Back to sub-freezing lows again Monday night with clear skies and
high pressure building in. Lows in the mid 20s are expected. This
intrusion of colder air should be brief, as warm air advection
ahead of another front moving through the western Great Lakes
early next week keeps things on the warmer side. Highs in the
lower 50s should warm into the 55 to 60 degree range on Wednesday
with lows warming as well into the lower to mid 30s.

This front seems to have a hard time pushing into the southeast
and hangs up over eastern Texas into the Ohio Valley. However, a
weak pre-frontal trough axis looks to be close enough to produce a
few showers over the area Wednesday night into Thursday.

This weak pre-frontal trough axis may focus a bit more moisture
and forcing over the area Thursday afternoon into Thursday night,
before pushing east of the area. This should pull the precipitation
east with it as colder and drier air moves into the area. Highs
look to drop back down into the upper 30s to lower 40s again on
Saturday.

.AVIATION...
(18Z TAFS)
Issued at 1114 AM CST Sat Dec 6 2025

The low cloud deck that brought IFR to MVFR CIGs this morning is
forecast to continue through much of the afternoon before lifting
late this afternoon through this evening. VFR conditions will then
return for a brief time; however, low to medium chances (20-40%)
of fog are anticipated to develop this evening and persist through
much of the overnight. This will bring at least MVFR VIS at the
terminals. By early Sunday morning, any fog is expected to
dissipate, with clouds on the increase once again. Overall, winds
will be light and variable to calm through the period.
