DISCUSSION

Issued at 1159 AM CST Tue Dec 2 2025

Tonight through next Monday...High pressure at the surface will settle over the region tonight. Some of the low clouds will erode across the area this evening into tonight. However, some mid/high clouds will begin streaming northwest into the region during the overnight hours into Wednesday morning. Due to this reason, ideal rational cooling conditions aren't expected in this particular airmass. As a result, I did bump up lows tonight from NBM suggested guidance a couple of degrees across the board. Still, a chilly night will exist across the CWA tonight as lows range from the upper 20s to lower 30s. Some patchy freezing fog is also possible across mainly northern portions of the area overnight. However, due to its scarcity and short duration, no impact is currently expected.

While the sun will peak in and out across the area Wednesday, mid/high clouds will continue to increase through the course of the afternoon as highs warm into the upper 40s to around 60. Come late Wednesday night, another shortwave moving out of the Four Corners region and into the plains, will result in increasing rain chances across mainly western portions of the CWA by sunrise Thursday morning.

Through the course of the day Thursday and into late Thursday night, showers will continue to increase in coverage across the forecast area as this trough continues to work its way east. Moisture will continue to lift northwest into the Lower Mississippi River Valley during this time, with a surface low pressure system finally developing and lifting northwest across the north central gulf coast. As the low continues its northwest journey across the Deep South into the Carolinas Friday through Saturday, both clouds and rain chances will gradually come to an end across the forecast area. Rainfall totals during this timeframe currently look to range from around one quarter of an inch to three inches, with the higher amounts currently forecast to be across areas south of the Interstate 20 corridor.

After Saturday, models are currently at odds with the timing and placement of the next system to quickly affect the area in the Sunday to Monday timeframe. Therefore, I'll maintain at least some isolated POPs in the forecast for Sunday, but keep Monday dry for the moment. /19/
