MESOSCALE UPDATE

Issued at 947 AM CST Thu Dec 11 2025

Although temperatures will be cooler today than on Wednesday, afternoon highs will be near normal. Northwest flow aloft will continue across our CWA while a surface high becomes centered over our southern zones. This will result in a light return flow that will gradually work to increase low level moisture back across our CWA. No significant changes were needed to the current forecast. /22/

DISCUSSION

Issued at 1250 AM CST Thu Dec 11 2025

Today and Tonight...A weak frontal boundary moved across the area on Wednesday and this resulted in a brief cooldown. Surface high pressure is centered over the area this morning and this will shift east of the area this afternoon. The flow will become southerly this afternoon, with temperatures mostly in the mid to upper 50s. Mostly clear skies will prevail through much of the night tonight, with some increase in clouds by morning. Lows will range from the upper 30s to low 40s. /15/

There will be a brief but significant warm-up Friday/Saturday in the return flow ahead of stronger cold front approaching from the north. A quick round of showers will accompany the front and bring light rainfall (less than a quarter of an inch on average), then much chillier temperatures will follow the frontal passage as we go from late Saturday night into early next week. Forecast confidence for this round of colder temperatures continues to increase, and the intensity of the cold forecast has increased just a bit more as more guidance points to a significant polar high surging south through the MS Valley.

The cold anomalies should be centered on Monday morning when lows could dip into the upper teens north of the Highway 82 corridor, but dangerous levels of cold are not expected for the most part and the coldest air will only make a brief visit. Look for temperatures to rebound and rainfall chances increase a bit as we go into mid next week. /EC/
