.NEAR TERM...
(Rest of tonight and Wednesday)
Issued at 959 PM CST Tue Dec 23 2025

A low to mid level stratus deck continues to cover northeastern
portions of the area and will continue to be the area of focus
overnight as it will determine which areas fog will be more
likely. With calming winds and clear skies across our western
areas, have the highest confidence in fog west of I-65 and south
of the Tennessee River but have added patchy dense fog across much
of the area through the morning hours. Overnight lows will fall to
the mid 50s across much of the area keeping our temps about 20
degrees above seasonal norms.

High pressure and westerly flow will continue to advect warm and
dry conditions to the area on Christmas Eve with afternoon temps
rising to the low to mid 70s. While we could see a few breaks in
the cloud cover tomorrow afternoon, mostly cloudy skies are
expected to continue into tomorrow night.

.SHORT TERM...
(Wednesday night through Friday)
Issued at 959 PM CST Tue Dec 23 2025

Changes to the overall synoptic pattern through the short term
period will be slow and minor, as high pressure shifts to the
southeast and flow aloft becomes more zonal. Temps will continue
to run about 20 degrees above normal for late December (normal
highs in the low 50s, lows in the mid 30s) as afternoon highs
reach the low to mid 70s both Christmas day and Friday. In fact,
lows will be even warmer, only falling to the upper 50s in most
locations. If the current forecast holds, we may tie or break
record highs at HSV (73/2016) and MSL (73/2016) on Friday.

.LONG TERM...
(Friday night through Tuesday)
Issued at 959 PM CST Tue Dec 23 2025

Saturday into Sunday will bring the last of the string unseasonably
mild days as an upper ridge shift east as a deep upper low and trough
swings southeast into the eastern CONUS. This brings a strong Arctic
cold front through the region late Sunday afternoon and evening. A
round of showers will occur with the front, although will need to
assess stability trends as we move closer given the strong bulk
shear. But at this time, no thunderstorms are forecast, but stay
tuned. After highs in the lower 70s Saturday and upper 60s Sunday,
the bottom drops out with readings falling into the 20s Sunday
night. Highs will be held to the 30s Monday and Tuesday, with
Tuesday morning lows in the teens. Blustery north winds of 10-20 mph
are expected Monday, diminishing greatly Monday night into
Tuesday.

.AVIATION...
(06Z TAFS)
Issued at 1205 AM CST Tue Dec 24 2025

An area of VFR stratus was slowly advecting to the SE across the
TN Valley. VFR conditions prevailed for most of the area. But
before the clouds moved in, fog has formed over the KMSL terminal,
producing 1/2SM VSBY. This fog may dissipate somewhat in the
overnight as more of clouds move in, but confidence level on when
this could occur is low. Fog should dissipate after sunrise with
daytime heating and more mixing realized. Model trends however
indicated that stratus should remain over the area through the
afternoon. Indications are the cloud bases should remain above
3kft, but some MVFR lowering cannot be ruled out.
