749 FXUS64 KBMX 281044 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 544 AM CDT Tue May 28 2024 ...New AVIATION... .SHORT TERM... (Today through Wednesday) Issued at 310 AM CDT TUE MAY 28 2024 Dry conditions expected today as high pressure build into the area under northwesterly flow aloft. The main upper low slow shifts through the Great Lakes region today through Wednesday with little change in the overall synoptic pattern as we head into the middle part of the week. Some guidance tries to bring in a weak upper shortwave through the Mid-MS Valley during the day on Wednesday, which could lead to some isolated showers and thunderstorms. However, the probability is low given the ridge and drier air mass in place. I`ve included 15-20% chance for rain/storms tomorrow afternoon/evening in the far western counties, but otherwise most of the area should remain rain-free. 25/Owen && .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... (12Z TAFS) Issued at 540 AM CDT TUE MAY 28 2024 LIFR conditions have developed across the far southeastern portions of Central Alabama, mainly impacting TOI with low VIS and low CIGs. This should improve soon after sunrise this morning, but I`ve included a TEMPO for LIFR through 14z. After 14-15z, conditions should improve at TOI, leading to VFR conditions for all sites through the remainder of the period. We`ll likely have a diurnal wind pattern with winds increasing during the daytime hours before becoming light and variable near or after 00-02z. 25/Owen && .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...
