.NEAR TERM...
(Rest of tonight and Monday)
Issued at 1038 PM CST Sun Dec 7 2025

A shortwave clipping the Tennessee Valley is bringing some
medium/high chances for light rain showers (50-80%) overnight.
Precipitation will be light, with QPF amounts being generally
under one-quarter inch or less. The rain chances combined with the
dense cloud cover will keep temperatures fairly steady overnight,
with lows only dropping to the upper 30s to lower 40s. This
quick hitting system will exit the area by daybreak. However, a
stout inversion may make it tough for cloud cover to erode (long
after rain tapers off) until the mid/late afternoon on Monday. As
a result, temperatures won`t budge much and it will feel like a
very chilly day as temperatures will only reach the mid 40s.

.SHORT TERM...
(Monday night through Thursday)
Issued at 1038 PM CST Sun Dec 7 2025

Dry conditions, with a gradual warming trend will occur Tuesday
and Wednesday as high pressure at the surface builds into the
region. Ample sunshine and surface winds gradually veering to the
south will help to modify the cool, continental air mass
somewhat. As a result, high temperatures will reach the low to mid
50s on Tuesday and the upper 50s on Wednesday (with a few
locations possibility reaching the 60 degree mark). A shortwave
trough will shift from the Ohio Valley into the Central
Appalachians, forcing a weak front into portions of KY/TN. While
this boundary will likely hang up north of the area, some cloud
cover and some very low (10-20%) chances for light rain are
forecast on Thursday as this shortwaves passes through the area.
Amplification of a broad upper trough over the Great Lakes will
eventually lead to additional shortwaves transversing the area and
a much colder air mass moving in. More on this in the section
below.

.LONG TERM...
(Thursday night through Sunday)
Issued at 1038 PM CST Sun Dec 7 2025

A couple additional shortwaves will traverse the southern flank of
a broad trough that will be amplifying over the eastern CONUS.
These subtle shortwaves will bring reinforcing shots colder, drier
air into the region. Highs on Friday will peak in the upper 40s
to lower 50s, with overnight lows dropping into the lower 20s.
Saturday and Sunday looks to be even chillier as high temperatures
will struggle to climb above the 40 degree mark both days -- with
overnight lows falling into the upper Teens to lower 20s both
nights. Any winds at all will result in even lower wind chill
values, especially Saturday night along the higher terrain. In
summary below normal temperatures will be favored late this week
into the very early part of next week which could favor temperatures
at least 10-15 degrees below normal for mid December. Review your
winter weather safety rules and prepare to bundle up!

.AVIATION...
(00Z TAFS)
Issued at 548 PM CST Sun Dec 7 2025

MVFR conditions will persist for the next several hours, however
the incoming rain showers have the potential to dip CIGS into IFR
at times at both terminals til ~08Z. After this, models continue
to suggest IFR CIGS will linger well into the morning hours before
MVFR CIGS return closer to 15Z. From here, MVFR will prevail and
northwesterly winds will be gusting up towards 15kts til sunset.
