.KEY MESSAGES...
Updated at 1030 AM CST Tue Dec 9 2025

 - No significant impactful weather expected during the period,
   but confidence is increasing in the potential of cold
   conditions early next week (~25% probabilities for low temps in
   the teens Monday morning).

.NEAR TERM...
(Rest of Today and Tonight)
Issued at 1030 AM CST Tue Dec 9 2025

Cool, dry conditions are expected today and tonight as an
elongated area of high pressure extending from the Gulf Coast
region into the NE Coast will hold sway over the region. A
shallow, low cloud deck that was present across NW portions of AL
this morning has gradually eroded with the onset of mixing this
morning. However, high ice-crystal clouds are crossing the area
today, and looking at their degree of opacity in satellite imagery
could have a small cooling impact on high temps. Those are
expected to reach into the upper 40s to around 50 this afternoon.
Light, patchy fog is expected in some locations tonight, probably
of the typical shallow/ground fog variety, as temperatures fall
into the low/mid 30s overnight.

.SHORT TERM...
(Wednesday through Friday)
Issued at 1030 AM CST Tue Dec 9 2025

The broad sfc ridge will retreat gradually to the east/south into
offshore territory as a longwave trough is carved into the East
CONUS on Wednesday. Ahead of the trough and a developing sfc
front, warm air advection amidst SW flow ahead of the front will
propel temperatures into the 50s on Wednesday. Winds may be a bit
gusty (~25 mph) at times on Wednesday, but short of any necessary
Advisory. The greater combination of dynamic lifting and
sufficient moisture will reside in the OH Valley and areas farther
to the NE with this system, thus a dry frontal progression is
expected across our area. Winds will shift from the NW Wednesday
evening with cold air advection allowing temperatures to fall as
low as the mid/upper 20s on Thursday morning. Temperatures are
expected to be a little colder again on Thursday, in the post-cold
frontal air mass, however, are expected to reach the mid/upr 40s
for most locations. The main caveat for Thursday will be the cloud
cover. The majority of ensembles indicate a low cloud deck
associated with the cold air mass should largely be to our north,
however, there is some disagreement among members, with some
indicating a low cloud presence over part of the area (greater
probabilities over northern locations).

.LONG TERM...
(Thursday night through Monday)
Issued at 1025 PM CST Mon Dec 8 2025

Slightly cooler than seasonal temperatures are forecast Thursday
night, with lows falling into the low/mid 30s. Closer to normal
readings will return on Friday with highs into the mid/upper 50s
under partly sunny skies. With cloud cover on the increase, lows
Fri night should range in the 30s.

Yet another storm system moving in from the WNW will bring lower
end chances of showers across mainly the western areas Saturday
afternoon. Rain chances should spread eastward across the Valley
Saturday night, then end from west to east over our eastern areas
Sunday morning. This system will bring colder air from up north to
across the eastern CONUS early next week. Lows Sat night should
cool from the upper 20s our Tennessee counties to mid 30s south of
the Tennessee River. A chilly airmass will be more noticed
Sunday, with highs only in the upper 30s north to mid 40s south.
The start of the next work week, Monday will be on the cold side,
with highs during the day into the mid/upper 40s.
