DISCUSSION

Issued at 327 AM CST Fri Dec 5 2025

Through tonight: Early morning surface analysis had a weak surface low just off the coast of the Florida panhandle and a >1020 elongated surface high just to our northwest. This high will shift east into our CWA and weaken while the surface low along the Gulf coast continues tracking east. This should result in a gradual decrease in rain chances from the northwest but models agree that southwest flow aloft will continue across our CWA through tonight. This southwest flow aloft will continue to draw up moisture and combined with very subtle disturbances, maintain low chances of light rain over the southeast half of our CWA through tonight. The rain chances and associated cloud cover combined with the continued caa from the surface high, will help keep temperatures cooler than normal again today. Although temperatures tonight will be near normal across our southeast, cooler than normal morning lows will continue at most locations as well. /22/

Overall, the prevailing upper-level pattern through the long term period looks to be rather subdued. Broad troughing over central CONUS this weekend, accompanied by multiple embedded shortwaves, will maintain lingering rain chances around the southern portions of the CWA, where a quasi-stationary boundary will remain just offshore of the Gulf Coast. Expect to see low to moderate rain chances at times, with temperatures generally in the 40s and 50s through this weekend. By early next week, the pattern will be more progressive as troughing shifts eastward and northwesterly flow aloft ushers in a cooler airmass behind a cold front. High pressure looks to build into the area by early-midweek, supporting a notable drop in temperatures. Lows Monday night may fall into the mid-20s areawide. Additionally, another cold front late in the period may bring additional rain chances toward the end of the forecast window. /KP/
