DISCUSSION

Issued at 336 AM CST Mon Dec 29 2025

Through Tonight: Latest surface analysis had the strong cold front pushing southeast of our southeast most zones. Strong gusty northwest wind of 30-40mph was being observed in the wake of the cold front. The Wind Advisory for our delta region will be cancelled but gusty winds of 30-35mph will continue over the CWA until becoming lighter later this morning. Local radars showed a narrow band of showers immediately along the front then some patchy light anafrontal rain back across central Mississippi. The light precipitation will end prior to sunrise. The large 1038mb high dropping out of the northern Plains will reach the southern Plains by this evening and then begin to shift east tonight toward our CWA. Although the wind will be lighter tonight, temperatures in the 20s will make it feel like it's around 20 degrees in our south. Despite lower temperatures and wind chills across the central and northern portions of our CWA, the new Cold Weather Advisory criteria will be met in the south and nowhere else in our CWA. Thus, our southern zones will be in a Cold Weather Advisory late tonight into Tuesday morning. After record high temperatures were set Sunday, today will feel brisk with high temperatures only in the 40s and wind chill temperatures in the 30s. /22/

Tuesday through Early Next Week Monday...

Weather conditions for Tuesday afternoon will be quiet and dry thanks to sfc ridging over the southeast CONUS. The pressure gradient will continue to weaken across the area heading into Tuesday afternoon/Tuesday evening. Sky conditions will be generally clear across our forecast for Tuesday with afternoon highs peaking in the low/mid 40s. Nighttime lows will dip into the mid 20s. Similar conditions are expected Wednesday and Wednesday night thanks to sfc ridging over the region. Temperatures will begin to rebound by the late week, with highs ranging mid 60s and lows in the 40s.

Revelers can expect a cold night for New Years Eve festivities, though thankfully not as cold as previous nights. We'll see temps begin to rebound on New Years Day. Continued surface ridging will maintain dry conditions through Thursday, but a few showers may return late Friday into early Saturday as a southern stream system moves across the Deep South. Thunder cannot be ruled out with that system, but the current timing does not appear to favor any severe threat. Heading into Sunday, the system will move out of our forecast area bringing an end to rain chances to finish off the weekend. Quiet conditions will persist heading into the new work week. /CR/
