MESOSCALE UPDATE
Issued at 723 PM CST Fri Dec 12 2025

DISCUSSION
Issued at 202 PM CST Fri Dec 12 2025

Through Saturday: Latest surface analysis had a ridge nosing west along the Gulf coast and a dry cold front approaching our northwest most zones. This ridge will hang tough through Saturday and the associated return flow will help increase low level moisture back across our southern zones. The cold front will drop into our northern zones this evening and stall nearly along and north of Interstate 20 Saturday. Thus, the low level moisture increase will be limited to the southern half of our CWA There will remain very low chances of mainly light showers across the southern half of our area tonight through Saturday. Thanks to the cold front, cooler temperatures and dry weather will reside across our northern zones while warmer than normal temperatures continue across our south.
There will be a chance of patchy dense fog late tonight into Saturday morning across our southern zones as well. /22/

Saturday night through Thursday: A potent shortwave dropping down the backside of a closed low that will be swinging across the Great Lakes region, will deepen upper level troughing over our region and help send a very cold and dry airmass toward our CWA This strong reinforcing cold front will drop into our northern zones shortly after sunset and push south of our southern most zones before sunrise Sunday morning. This cold front will increase rain chances as it moves into our CWA with the greatest chance for rain over the southern half of our CWA No wintry mix precipitation is anticipated in our CWA Saturday as the precipitation is expected to end well before the subfreezing temperatures move into our northern zones.
Morning lows Sunday morning are expected to be at or below freezing along our Highway 82 corridor.

Sunday through Monday the center of an arctic airmass will be tracking east southeast across the mid Mississippi valley and to the southern Appalachians. This will result in a gusty north wind across our CWA Sunday that will hold temperatures well below normal.
Bolivar and Sunflower counties may not rise above freezing Sunday.
Dangerously cold conditions are still expected over the CWA Sunday night. Morning lows Monday are expected to be in the teens across the north to the lower 20s across the south. With the surface high to the northeast the wind will likely remain up through the night resulting in wind chill temperatures over our whole CWA of 10-15 degrees. These cold temperatures pose a threat to people, pets, pipes, and plants. Temperatures Monday will top out in the 40s areawide before bottoming out in the 20s areawide Tuesday morning.

Models differ on the details but our flow aloft will become near zonal Tuesday into Wednesday and surface ridging will remain over the Gulf coast states from the east. This will allow for a warming trend to back above normal temperatures by Thursday. Tuesday will be dry but a couple disturbances may bring some rain to portions of our CWA Wednesday and Thursday. /22/
