MESOSCALE UPDATE

Issued at 650 PM CST Thu Jan 29 2026

A weak low surface pressure system sliding southeast from OK/AR toward the Gulf Coast tonight will bring a shift to northwesterly winds and low cloud cover overnight.

DISCUSSION

Issued at 143 PM CST Thu Jan 29 2026

Tonight through Wednesday night:

Tonight through Friday:

Longwave trough over the eastern CONUS will push a cold front towards the area tonight. Increasing cloud cover with light winds expected for the overnight hours as the next cold front moves into the area. The aforementioned front is expected to be dry with low (> 15% PoPs) rain chances however, a few rain showers/flurries may be possible with any available moisture. No impacts are expected if flurries are present. Patchy fog/freezing fog can't be ruled out early Friday morning. A potent cold front will drop an arctic airmass into the region on Friday, significantly dropping high/low temperatures for the weekend. Will be upgrading Extreme Cold Watch to an Extreme Cold Warning for Friday night into Saturday morning with this update.

Saturday-Sunday:

Post-frontal passage, cold temperatures and breezy winds are expected Saturday as a surface high progress into the region. Highs are only expected to reach near freezing in the Pine Belt, elsewhere highs will be in the upper 20s to near 30 degrees. Along with dangerously cold temperatures, winds are expected to be strong throughout Saturday with sustained winds ranging between 20-25 mph and gusts between 35-40 mph. Strong winds will result in wind chills below zero degrees to single digits, increasing cold weather danger along with impacting ongoing restoration efforts from the previous winter storm. For any areas with continued icy/slick roadways and extended power outages, ensure to know your safety precautions with generators and keep warm the best you can this weekend. Will be adding an areawide Cold Weather Advisory for Saturday night into Sunday to account for lighter winds and remaining cold temperatures. Winds will begin decreasing overnight Saturday into Sunday and temperatures won't be as cold as the previous day with highs reaching the upper 30s to lower 40s on Sunday. Overnight lows for Sunday will range in the 20s.

Monday-Wednesday night:

Surface high will gradually slide to the east, allowing for southerly/southeasterly flow to return to start the week. Temperatures will remain below seasonal averages and ranging from the upper 40s in the north to near 60 degrees in the south by mid- week. A shortwave disturbance will begin pushing towards the southeast CONUS, bringing widespread rain chances (50-60% PoPs) to the region Wednesday and beyond extended period. /SW/
