896 FXUS64 KBMX 170524 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 1224 AM CDT Tue Jun 17 2025 ...New AVIATION... .SHORT TERM... (Tonight through Wednesday) Issued at 1118 PM CDT MON JUN 16 2025 Low pressure will develop and strengthen over the Ohio Valley and move northeast. A mid level jet around this low will move across the area this afternoon. With low and mid level flow prevailing out of the southwest and the higher winds with the jet, plenty of warm and moist air will be advected, with PW values max climatologically for this time of year. Diurnal convection will be possible this afternoon, with a moderate chance for more widespread coverage through the evening and early night. Strong winds will be the main threat. Localized flooding will be a threat in any of the stronger activity that can train. Wednesday will be more of the same with diurnal convection. 24 && .LONG TERM... (Wednesday night through next Monday) Issued at 1118 PM CDT MON JUN 16 2025 By Wednesday night, a low pressure will move just south of the Great Lakes region, and trailing a boundary across the eastern US. This boundary is expected to move through the state in the afternoon on Thursday, with convection developing through the afternoon and the early part of the night. Low level flow out of the southwest Wednesday will transition to more of a westerly flow by Thursday. There should be plenty of moisture for high rain rates, and with the flow parallel to the boundary, a localized flooding threat may be higher on Thursday. The boundary will move to somewhere in the southern half of the state before stalling through Friday. Models are in decent agreement that the convection on Friday will mostly be in the southern half of the state, with higher PW values from the westerly flow along and south of the boundary. North of the boundary, northwest flow will bring cooler and drier air and limit the chance for much convection. By Saturday, the boundary moves south with high pressure strengthening over much of the southeastern CONUS. Scattered diurnal activity will prevail each afternoon through the beginning of next work week, with light wind profile and plenty of instability bringing a chance for strong winds and small hail with any activity each day. 24 && .AVIATION... (06Z TAFS) Issued at 1219 AM CDT TUE JUN 17 2025 Southwest flow will bring plenty of low level moisture for fog development overnight tonight. Left MVFR visibilities for now at every site except KMGM where IFR visibilities and even LIFR visibilities will prevail through he night. Diurnal convection is expected again in the afternoon through the early night. Uncertainties remain on exact placement of storms and timing, so left a PROB30 in for now and will adjust when confidence increases. NOTE: AMD LTD TO CLD VIS AND WIND has been added at MGM until further notice due to comms issues. 24 && .FIRE WEATHER... A disturbed pattern will remain across the area, with showers and thunderstorms remaining in the forecast through the weekend. Given the moist airmass overhead, MinRH values will remain over 50% during this timeframe as well. && .PRELIMINARY POINT TEMPS/POPS...
