142 FXUS64 KBMX 281724 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 1224 PM CDT Tue May 28 2024 ...New SHORT TERM, AVIATION... .SHORT TERM... (This evening through Wednesday) Issued at 1216 PM CDT TUE MAY 28 2024 High pressure will develop over the MS River Valley and slowly move east through the short term. Mid level flow will remain out of the north today, limiting the amount of moisture advection to the state, leaving mostly clear skies and high temperatures in the upper 80s and lower 90s. Wednesday morning, as the high pressure moves east, flow will shift to out of the southeast, bringing warm and moist air beginning to advect into the western part of the state. A shortwave will move across the south, causing showers and isolated thunderstorms to develop to the west of Alabama. However, instability will be fairly limited, so models diverge on how much activity will be over the state. Opted for a optimistic scenario with an increase in clouds and an isolated small cell to occur over western third of Central Alabama, but otherwise, the area should remain mostly dry. 24 && .LONG TERM... (Wednesday night through next Monday) Issued at 310 AM CDT TUE MAY 28 2024 Weather conditions in the long term look to be dominated by rather progressive upper level flow, with several shortwaves zipping through periodically. Difference in timing/placement and strength of individual shortwaves among the various models leads to a somewhat low confidence forecast. Looks like one wave approaches the area on Friday, and another on Saturday, both if which could lead to periods of slightly enhanced POPs. Otherwise, we may be entering a more summertime weather regime, with daily diurnal convective chances being driven by mesoscale processes not handled well by the long range global models. /61/ && .AVIATION... (18Z TAFS) Issued at 1216 PM CDT TUE MAY 28 2024 VFR conditions will prevail through the TAF period. High pressure will move over the state with high to mid clouds increasing on Thursday. 24 && .FIRE WEATHER... Dry conditions expected today and tomorrow with Min RHs dropping into the mid to upper 30% range. Northwesterly winds could be gusty at times this afternoon before becoming light and variable during the overnight periods. Moisture gradually increases as we go into Thursday. && .PRELIMINARY POINT TEMPS/POPS...
