.NEAR TERM...
(Rest of Today and Tonight)
Issued at 954 AM CST Mon Dec 8 2025

Northerly winds this afternoon are contributing to mostly dry
conditions as well as highs remaining in the mid 40s under
lingering cloud cover. Tonight, temperatures drop to below
freezing throughout most of the TN Valley, which will be combined
with small dew point depressions and calm winds. In turn, at least
patchy, freezing fog is forecast throughout the area. We will be
monitoring how widespread this fog will potentially be in the
afternoon and evening updates. There is currently a low-medium
chance of a Freezing Fog Advisory being issued. Be sure to use
caution on your morning commute tomorrow!

.SHORT TERM...
(Tuesday through Thursday)
Issued at 954 AM CST Mon Dec 8 2025

As upper level ridging and subsequent sfc high pressure influences
the TN Valley from the west, the sun will finally be seen again on
Tuesday under clear skies. Highs are forecast to rise into the
upper 40s to lower 50s with southwesterly winds around 5-10 mph
with gusts up to 15 mph. Wednesday, temps are forecast to be a bit
warmer (rising into the mid to upper 50s) ahead of a shortwave
trough and subsequent weak cold front forecast to sweep southeast
into the area overnight into Thursday. This will bring increased
cloud cover throughout the day on Wednesday as well as a very low
(10% or less) chance of precipitation. Depending on the timing of
this front, precipitation could fall overnight into Thursday
morning in the form of a few flurries. However, confidence in this
is low. If this were to be the case, no impacts are forecast.

.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...
(18Z TAFS)
Issued at 1150 AM CST Mon Dec 8 2025

The low stratus deck will keep at least MVFR CIGs and slight VIS
reductions in place at the terminals through much of the
afternoon. However, by late this afternoon, the clouds will start
moving to the south and/or dissipating and VFR conditions will
return this evening. This will be short-lived as patchy to areas
of fog have a low to medium chance of developing tonight, bringing
MVFR VIS to the terminals. We will monitor trends and
observations through late this evening in case fog becomes dense,
but confidence is low to medium in this occurring. As for winds,
northwest winds around 10 knots this afternoon with gusts to
around 15 knots will decrease to be light to calm this evening.
After calm winds overnight, southwesterly winds around 5 knots is
then expected to develop Tuesday morning.
