.DISCUSSION...
(This evening through next Tuesday)
Issued at 1201 PM CST Wed Dec 3 2025

Clouds are breaking up along the TN River and AL border and
across NE MS and SE West TN. We should continue to see
improvement in those aforementioned areas, while cloud cover
further north and west still looks fairly thick and unchanged.
HRRR is fairly aggressive at keeping clouds in through the night,
though the latest trends are resulting in some doubts.

Obviously, cloud cover will impact low temperatures tonight. We
used the HRRR as a starting point and dropped temps in eastern
sections where the cloud cover is showing signs of breaking up.
Some weak overrunning caused by a shortwave passing by to the
north could bring some light showers to north MS early Thursday.
Temps will be right around the freezing mark, so there is a low
chance (<15%) of light freezing rain for a couple of hours across
extreme NE MS. That first shot of precip will move out by mid-
morning followed quickly by the next more organized system.

A fast moving shortwave tracking from the Southern Plains will
initiate another round of overrunning starting late Thursday
afternoon continuing into Thursday night. Models are a bit all
over the place with just how far north the shield of
precipitation will stretch. Latest GFS and HRRR are trending more
south, with the ECMWF much further north, so uncertainty remains
high.  There is a less than 40% chance of a wintry mix Thursday
night across parts of NE AR, the MO Bootheel and NW TN. Forecast
soundings support a little light snow to start, mixing with and
changing to freezing rain. Amounts will be quite light. Where the
cold air is in place, QPF amounts are expected to be less than
0.05 inches, so we are not looking at significant impacts at this
point. Slippery bridges and elevated surfaces are the most likely
impacts. A more southerly precip shield shown by some solutions
would move the wintry mix further south, potentially into the
Memphis metro with locations along the KY/MO border not seeing
much of anything.

Precip will pull out early Friday with weak surface high pressure
prevailing and clouds lingering. Temps will be cool with highs in
the 40s. Generally, benign weather with below normal temperatures
will prevail this weekend into early next week under fast morning
W/NW zonal flow aloft with weak systems

.AVIATION...
(00Z TAFS)
Issued at 532 PM CST Wed Dec 3 2025

MVFR cloud deck currently resides across western portions of the
airspace and is expected to expand eastward over the next few
hours. Still some uncertainty with the timing, but think MEM will
drop to around to after 04Z with MKL following by 08Z. Will
likely be a quick drop to IFR thereafter. Leaned a bit more
pessimistic with the cigs and do not have improvements for most
of the area through the end of the TAF period. Variable winds
will go northerly by around 08Z, picking up to around 8 to 10 kts
by midday. Precipitation into tomorrow remains a bit of a
question mark with the system, so have left as PROB30s for most
MEM/TUP.
