667 FXUS64 KBMX 301714 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 1114 AM CST Tue Dec 30 2025 ...New AVIATION... .KEY MESSAGES... Updated at 1113 AM CST TUE DEC 30 2025 - Cold weather expected to continue today with gusty winds keeping wind chills in the 30s for most of the area. - High chance (80-90%) for rain Friday with 30% chance of thunderstorms. && .DISCUSSION... (Tuesday through next Monday) Issued at 1115 PM CST MON DEC 29 2025 Cold and dry conditions are expected again today across Central AL. High temps will remain in the 40s with a few spots across the north struggling to hit 40. Northwesterly flow aloft will persist through at least midweek with diurnal temperatures moderating slightly as we go through Wednesday and into Thursday. A shortwave trough will slide through the Plains and develop a low pressure system Thursday into Friday. This low will slide through Central AL leading to increased rain and thunderstorm chances. The upper level pattern remains generally zonal with little upper level height falls, so the big question will be whether the warm front lifts far enough northward for a more moist air mass to advect into Central AL. For now, I'll continue mention for low chances (20-30%) of thunderstorms Friday into early Saturday. A the low shifts eastward, high pressure builds into the Southeastern CONUS Sunday into Monday. This will lead to rain-free conditions and seasonable temperatures for the start of next week. 25/Owen && .AVIATION...
