077 FXUS64 KBMX 201937 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 237 PM CDT Mon May 20 2024 ...New LONG TERM... .SHORT TERM... (This afternoon through Tuesday) Issued at 1156 AM CDT MON MAY 20 2024 A large ridge over the East CONUS will support a period of warm and dry weather. The mid-level ridge axis extends from the Lower MS Valley northeast into New England producing northwest flow aloft. The surface ridge is extending down the spine of the Appalachians producing a light easterly surface wind across the area. Some weak surface convergence may kick off a shower or two in the west this afternoon where a field of cu has developed, but mostly sunny skies will be the story for the next couple of days with highs in the mid to upper 80s. Clear and mild tonight with lows in the 60s, and a small chance of some patchy fog early tomorrow morning. 86/Martin && .LONG TERM... (Tuesday night through next Sunday) Issued at 222 PM CDT MON MAY 20 2024 Upper ridging over the northern Gulf of Mexico will keep rain free conditions across Central Alabama Wednesday and into Thursday. The northern edge of the ridge will begin to weaken on Friday as an upper level short wave trough tracks along the southern fringe of the westerlies. This will produce sufficient lift for scattered convection across the northern half of Alabama. Once this upper impulse slides east of Alabama, the ridge could ease back northward and result in lower rain chances on Saturday. Above normal temperatures during this period with highs in the upper 80s to lower 90s. 58/rose && .AVIATION...
