DISCUSSION

Issued at 332 AM CST Sun Dec 7 2025

Through tonight: Similar to the last several mornings, surface observations and satellite imagery showed a layer of stratus covering the whole CWA. This layer of stratus has remained elevated and dense fog has not yet developed. It remains possible that towards sunrise this layer of stratus will become surface based and areas of dense fog will result so the Dense Fog Advisory will remain in effect until 9AM. Temperatures were running warmer this morning thanks to return flow provide by surface ridging nosing across our CWA from the east. Latest surface analysis also showed a cold front emanating from a weak surface low over the mid Mississippi valley and a second surface low over the southern Plains. As a shortwave trough approaches our CWA today and moves across our CWA tonight, it will support the cold front swinging across our region. Rain will develop this morning along and ahead of the cold front and move into our western zones prior to noon. The rain and perhaps a few rumbles of thunder south of Interstate 20 this afternoon will continue into the evening before tapering off from the west after midnight. Dry weather is expected before sunrise Monday morning. Temperatures will warm just above normal today ahead of the cold front and remain slightly above normal tonight until the colder air in the wake of the front moves into our CWA Monday. /22/

Monday through Next Saturday: Behind the early-week cold front, an impending plunge of polar air will bring dry conditions to much of the ArkLaMiss region for a majority of the forecast period. Temperatures will trend seasonable cold, with Monday night/Tuesday morning still expected to be the coldest period. Low temperatures will fall into the upper 20s to low 30s, with potential to fall into the mid-20s in some areas. Temperatures will then moderate to near or slightly above seasonal averages for Wednesday and Thursday. By late week, another cold front is expected to approach the region, bringing the potential for the return of rain chances. In the wake of this front, temperatures may again plummet into the mid-20s, with highs struggling to reach 50 heading into next weekend. While this colder scenario is possible, model consensus remains limited at this range. /KP/
