- Colder weather should return Sunday and persist into early next week.

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

(00Z TAFS) Issued at 539 PM CST Tue Dec 9 2025

VFR conditions are expected through the TAF period. Patchy fog cannot be entirely ruled out in south MS and south LA, 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. /DL/
