.NEAR TERM...
(Rest of Today and Tonight)
Issued at 1026 AM CST Wed Dec 10 2025

Bottom line up front: breezy today but temperatures near seasonal
norms in the low to mid 50s.

A shortwave will round the trough of the upper level low up in
Ontario today. There is a low chance (10-15%) that this could
squeak out a few showers, however the bigger forecast concern
today are the winds. The sfc pressure gradient will continue to
tighten between the high sitting along the southeastern Atlantic
Coast and a sfc low tracking into the Lower Great Lakes. This sfc
low will also pull a cold front into the TN Valley later today.
The southwesterly winds ahead of the front have already picked up
with gusts reaching 20-25 kts. This will help us reach the low to
mid 50s which is warmer than we have been but closer to normal
values for this time of year. The front is expected closer to
dinner time and gusty winds will shift to become northwesterly.The
cold air advection will drop overnight lows into the mid to upper
20s which is about 10 degrees cooler that last night. Be sure to
bundle up tonight and tomorrow morning for the bus and morning
commute.

.SHORT TERM...
(Thursday through Saturday)
Issued at 1026 AM CST Wed Dec 10 2025

Off to a cold start Thursday morning with temps in the mid to
upper 20s. Behind the cold front that will pass through Wednesday
night, higher pressure will spread in and keep northwesterly winds
around for most of the day on Thursday. This will provide a brief
cool down with highs in the low to high 40s despite mostly sunny
skies. Friday will see the warm up as high pressure glides
through and returns southwesterly flow 5-10 kts with gusts up to
15-20 kts. While we sit in high pressure on Friday, a sfc low will
ride through the OH Valley and pull a weak front into the TN
Valley Friday night and return northerly flow. Winds will be
light, however overnight lows will be around freezing. Saturday
will be tranquil and mild with highs in the low to mid 50s,
however precip chances return Saturday night along with a blast of
arctic air. More on that in the Long Term below, and stay updated
with the latest forecast for this weekend as we get closer.

.LONG TERM...
(Friday night through Tuesday)
Issued at 1052 PM CST Tue Dec 9 2025

High pressure at the surface will promote fairly tranquil
conditions Friday night into Saturday, with zonal flow continuing
aloft. This will result in another fairly mild day on Saturday
with high temperatures reaching the mid to upper 50s once again. A
weak shortwave will bring another cold front through the area.
Modest moisture return ahead of this feature should allow for some
low chances (20-30%) for light precipitation Saturday night,
before rapidly tapering off between 09-12z Sunday morning.
Depending on the timing there could be a brief window for
precipitation to mix with snow (with no impacts), but for a vast
majority of locations think this will remain a cold rain -- with
precipitation ending by the time the subfreezing air arrives.

A much colder air mass will arrive on Sunday, with highs
struggling to climb much above the 40 degree mark. Then, a clear,
cold, dry night will knock lows into the upper Teens to lower 20s
Sunday night. This colder air mass will quickly begin to modify
monday and Tuesday as high pressure builds in and winds veer back
to a southerly direction. This will allow highs to climb back to
seasonable norms.

(18Z TAFS)
Issued at 1052 AM CST Wed Dec 10 2025

VFR conditions are forecast to continue through the TAF period at
KHSV. KMSL has MVFR conditions that should return to VFR by late
this afternoon. At both sites, gusty NW winds are forecast through
this afternoon with gusts reaching ~25 kts. While no wind shear is
being observed within 2kft, there is unidirectional wind shear
above that layer, with wind gusts increasing to ~50 kts by 4-5kft.
