.NEAR TERM...
(Today)
Issued at 323 AM CST Fri Dec 12 2025

Early this morning some passing clouds were noted on satellite
imagery, but otherwise tranquil conditions continue across the
Tennessee Valley. With high pressure at the surface in control of
our sensible weather and winds veering to the south, temperatures
will rebound nicely today (especially once clouds begin to thin
later in the day). Highs in the mid to upper 50s will be common,
with a few locations reaching the lower 60s.

.SHORT TERM...
(Friday night through Sunday)
Issued at 943 PM CST Thu Dec 11 2025

Our main concerns in the short term period are the very cold
temperatures and wind chill temperatures forecast to move in
Saturday night into Monday morning. An upper level low is forecast
to shift eastward into the Appalachian region on Friday, bringing
a cold front southeastward through the TN Valley. An additional
low pressure system is forecast to traverse eastward through the
Great Lakes region, bringing a secondary cold front to the area by
Saturday night. This secondary front is forecast to bring very
cold conditions to the TN Valley by the late weekend. Ahead of
this, a low chance (10-30%) of precipitation will be possible
Saturday evening into early Sunday. Model soundings have been
trending drier (both in the snow growth region as well as
throughout the profile), allowing confidence to decrease in
precipitation forming within this update. However, we will
continue to monitor trends through Saturday. If any precipitation
manages to overcome the dry layers, it will likely begin as
drizzle before transitioning to freezing drizzle/sleet as
temperatures drop below freezing. If this is the case, a few
tenths of an inch of accumulation (primarily on elevated surfaces
and bridges) could occur. However, increased winds and a
relatively warm ground should prevent significant slick spots on
roadways.

As stated previously, our largest concern is the very cold
temperatures forecast to accompany the secondary cold front as it
pushes through Saturday night. Lows Saturday night are forecast to
drop into the mid 20s with post-frontal highs on Sunday remaining
in the mid to upper 20s through most of the area. Due to the
elevated winds, wind chill temperatures are forecast to be in the
single digits Sunday morning. Be sure to bundle up in multiple
layers if venturing out Sunday and limit time outdoors. Additional
cold temperatures are forecast through Monday before a gradual
warm up through mid week. More on that in the long term below.

.LONG TERM...
(Sunday night through Thursday)
Issued at 943 PM CST Thu Dec 11 2025

Bitterly cold conditions will continue Sunday night as temperatures
around 20 after dusk, tumble into the low/mid teens for night time
lows. Northerly winds at 5-15 mph early in the evening, will
diminish below 5 mph in the overnight. For the most part, wind
chill or apparent temperatures stay above 5 degrees Sunday night,
which is just above our Cold Weather Advisory threshold.

Expect a chilly start to the work week. Under sunny skies, high
temperatures Monday should rise into the mid 30s to around 40.
Light northerly winds should veer to the SE-S at 5-10 mph in the
afternoon. Not as cold Monday night with lows in the low/mid 20s and
light winds. Conditions will moderate as we go through the mid week,
with highs on Tuesday in the mid/upper 40s, Wednesday in the low/mid
50s, and in the lower 60s Thursday. Lows Tue night will range in the
low/mid 30s, and in the 40s Wed night.

Clouds will also be on the increase Tuesday into Thursday, as a storm
system slowly develops to our west. This next system will bring low
to medium (20-50%) chances of rain to the area beginning late Wed
afternoon and going into Thu. This precipitation should be more
stratiform than convective in character, as it will be on the
"overrunning" side of the developing system. The moisture upglide was
apparent in the 295-300K regions late Wed into Thu.
