.MESOSCALE UPDATE...
Issued at 858 PM CST Tue Dec 9 2025

Thanks to mostly clear conditions and light wind, some areas have
cooled off rather quickly this evening, dipping into the upper
30s. Overnight, an increase of high clouds and steadier wind ahead
of an approaching front will cause temps to level off or possibly
even rise a degree or two in some areas. However, some more
sheltered areas may still get down into the mid 30s or even close
to freezing. Prob guidance is also suggesting potential for
patchy fog across south MS overnight, which was already reflected
in the going forecast. No major adjustments are planned for the
near term at this time. /DL/

.DISCUSSION...
Issued at 211 PM CST Tue Dec 9 2025

Tonight through next Monday night: Dry northwest flow aloft will
be the primary weather influence in our area, and this will result
in seasonable temperatures with little chance for any more than
light rainfall as we finish up this week and go through the
weekend. A cold front passing through the area Wednesday
afternoon will bring a glancing shot of colder air that will
result in freezing temperatures Wed night for mainly
northern/eastern portions of the area.

There will be a brief warm-up Friday/Saturday ahead of another
approaching cold front, then much chillier temperatures will
follow the frontal passage as we go from Sunday into early next
week. Forecast confidence for this round of colder temperatures has
increased some as more guidance points to a significant polar
high surging south through the MS Valley. It seems the cold
anomalies should be centered on Monday morning, but dangerous cold
is not expected. Look for temperatures to rebound and rainfall
chances increase a bit as we go later into next week. /EC/

.AVIATION...
(06Z TAFS)
Issued at 1117 PM CST Tue Dec 9 2025

VFR conditions are expected to prevail through the TAF period at
most sites. Patchy fog cannot be entirely ruled out in south MS
and south LA Wed morning, but confidence is not high enough to
warrant mention in TAF. A dry cold front will begin to push across
the region overnight through the day Wednesday. This will result
in LLWS around GLH, GWO, and GTR overnight. Then surface winds
will become gusty areawide during the daytime Wednesday and shift
to W and NW. A brief period of MVFR ceilings is possible with the
passage of the front at GLH and GWO, but VFR conditions should
quickly return. /DL/
