MESOSCALE UPDATE

Issued at 933 PM CST Fri Jan 30 2026

Latest satellite imagery/RAP analysis showed a potent shortwave dropping south of the mid Mississippi valley toward our area. This shortwave will deepen and close off a low over northern Alabama by sunrise and help draw south an arctic airmass across our region. A few site were observing gusty winds this evening but stronger winds and gusts will arrive with the cold air and result in dangerously cold wind chill temperatures prior to sunrise. Most sites were already below freezing. /22/

DISCUSSION

Issued at 1248 PM CST Fri Jan 30 2026

Tonight through Sunday:

Arctic air will begin filtering into the region tonight as a strong cold front pushes through the southeast CONUS. Dangerously cold temperatures are expected overnight (lows: teens to near 20 degrees) and Saturday (highs: upper 20s/near 32 degrees). Along with the arctic airmass, winds will start increasing as both a developing low near the East Coast and the incoming surface high in the Central Plains strengthens, creating 6mb pressure gradient over the area. Sustained winds between 20-25 mph with gusts between 30-35 mph are expected, resulting in wind chills ranging between below zero degrees to single digits. With that being said, an Extreme Cold Warning will go into effect late tonight through Saturday afternoon. Continue to take cold weather precautions and keep warm this weekend. The surface high will push into the region, allowing for the pressure gradient to decrease over Saturday evening. Winds will continue to subside into Sunday; however, highs will remain cold but rise above freezing Sunday. Overnight lows for Sunday will range in the 20s. A Cold Weather Advisory will replace the Extreme Cold Warning and go into effect for Saturday afternoon through Sunday afternoon to account for lighter winds and remaining cold temperatures.

Monday through Thursday night:

Surface high will migrate eastward, advecting moisture and increasing temperatures areawide. Highs(ranging upper 40s-near 60 degrees) / lows (ranging in the 30s to mid 40s) will continue to run below seasonal averages. Rain chances return for Tuesday through Wednesday with the best chances being Tuesday night as PoPs reach 60- 70% areawide as a shortwave disturbance moves in from the southwest. Once the shortwave passes through, a quiet weather pattern is expected Thursday and beyond. /SW/
