(Tonight through Sunday night) Issued at 1233pm CST Fri Dec 12 2025 A warm front has lifted inland this morning allowing humid marine air to infiltrate through forecast area. Additionally isolated showers will wain through the early evening. With the addition of warmer dewpoints across the region another round of patchy dense fog is expected to occur overnight. Areas of fog and low clouds may stick around through the mid morning. The stalled warm front will remain to our north through Saturday evening keeping temperatures well above normal. A weak upper level disturbance will migrate across the northern Gulf and begin to phase with the massive shortwave pattern deepening across the Eastern U.S. Both features will help to create a sharp drop temperatures going into Sunday. Scattered showers will increase into the early morning hours Sunday with the advancing Canadian cold front toward the coast. A few pockets of efficient rainfalls are likely during the overnight hours, however, widespread substantial over 0.25" rainfall amounts are less likely. High temperatures Sunday will be occurring around midnight(12:00AM) Sunday with temperatures steadily falling through the afternoon. Skies are projected to clear by the afternoon; temperatures will be falling below 40°F shortly after sunset. Big focus on the short range will be the precariously cold lows and windchills overnight into Monday morning.

Kowalski / 30 Long Term (Monday through next Thursday) Issued at 1233pm CST Fri Dec 12 2025 Cool highs in the 40's will trend across the forecast area Monday with the northerly advection. The robust high pressure will quickly broaden eastward over the Carolinas by Tuesday. Winds will veer onshore overnight into Wednesday allowing temperatures to begin a warming trend through the later half of the week. A few convective showers may develop pending the depth of any low/mid level inversions during the mid week. However, much of the long range will trend dry through the end of next week. This onshore regime will persist until the following weekend offering above normal highs in the 60's and 70's.
