.NEAR TERM...
(Today)
Issued at 345 AM CST Sat Nov 29 2025

Early morning temperatures have fallen into the upper 20s/lower
30s with light winds and increasing high clouds. Temperatures will
be slightly warmer today as an approaching shortwave trough
pushes the surface high east of the Appalachians and sc flow
slowly begins to veer to the southeast. The resultant CAD setup
will cause dry air to linger in the lower levels throughout the
day today. After some likely virga in the afternoon, an area of
showers will move in from the west ahead of an approaching cold
front in the evening hours. Light to occasionally moderate showers
will continue through the overnight hours with rainfall amounts
generally less than 0.25".

.SHORT TERM...
(Sunday through Tuesday night)
Issued at 958 PM CST Fri Nov 28 2025

Rain will continue through midday Sunday, with temperatures only
bottoming out in the upper 30s to low 40s overnight, which removes
any potential for wintry precipitation. Sunday will be dreary in
the morning with lingering cold rain and then only warm into the
mid to upper 40s.

Post-frontal upper level flow becomes more zonal behind the
shortwave trough. Sunday night will see temperatures drop into the
mid 50s, but winds gusting 15-20 mph will cause wind chills to
reach the mid-teens. Progressing into Monday, the subtropical jet
phases with the primary jet ahead of an approaching longwave
trough. A surface low pressure system tracking along the northern
Gulf coast will stream moisture northward into the TN Valley.
Cloud cover increases Monday afternoon and rain pushes in from
the southwest, continuing through Tuesday afternoon. Temperatures
steadily decrease from the mid 40s Tuesday morning down to the
upper 20s by Tuesday night. While the trough axis and attendant
surface low push east of the area by Tuesday night, the fly in the
ointment would be any wrap around moisture while surface
temperatures are sub-zero. A passing jet streak may provide
sufficient lift to produce non-impactful flurries Tuesday night,
but confidence is very low (10% chance).

.LONG TERM...
(Wednesday through Saturday)
Issued at 958 PM CST Fri Nov 28 2025

The cold air mass remains over the Southeast through the
remainder of the work week. Surface high pressure will track over
the Southeast Wednesday. Southerly return flow on Thursday will
increase cloud cover throughout the day. There is disagreement
between global ensemble models in how quickly the next system
arrives. At this point, it looks like late next week into the
weekend will see a return of rain. We will need to monitor how
this overlaps with the arrival of colder air. Otherwise, high
temperatures will peak near 50 each day with lows in the upper 20s
to low 30s.

.AVIATION...
(12Z TAFS)
Issued at 550 AM CST Sat Nov 29 2025

VFR conditions are forecast through much of today with increasing
chances for rain and wind shear toward the overnight hours.
Increasing high clouds are expected this morning and mid level
cloud cover will begin to filter in late this afternoon ahead of
our next storm system. Rain chances will increase around 00z at
KMSL and spread east through the overnight hours. Periods of MVFR
conditions are forecast through the overnight hours into tomorrow
morning and we have maintained southern wind shear near 40kts at
2kft tonight at KMSL.
