026 FXUS64 KBMX 150547 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 1247 AM CDT Thu May 15 2025 ...New LONG TERM... .SHORT TERM... (Today through Friday) Issued at 1212 AM CDT THU MAY 15 2025 Clear skies across the area right now. Some patchy low clouds/fog will slide in from the south by daybreak, much like this past morning. That mixes out by late morning and southerly flow will bring in some warmer conditions with mostly sunny skies. Some locations in the south will warm into the lower 90s as low-level ridging centers over the northern Gulf. We will continue to see warm temperatures on Friday as well ahead of a frontal boundary to our north. Right now it looks like like most of the rain will remain to our north through Friday afternoon. Highs on Friday will be a degree or two warmer than today with readings in the upper 80s north to low 90s south. 16 && .LONG TERM... (Friday night through next Wednesday) Issued at 1212 AM CDT THU MAY 15 2025 A low pressure will deepen and move over the Ohio Valley, with a frontal boundary moving into the area Friday night through Saturday evening. Rain and thunderstorms could move into the northwestern counties after midnight, with activity increasing in coverage by mid morning. As the front sags south, most of the area should see showers and thunderstorms by the early afternoon, continuing through the evening. Instabilities are high, with 3000 J/kg plus forecasted right now, and plenty of shear. Will have to analyze the severe potential as the front gets closer. Uncertainties include how quickly the front makes it into the area and how much convection will occur through the morning ahead of the stronger afternoon storms. Sunday, high pressure develops over the Gulf with flow turning to the west and southwest around this high. A shortwave is expected to move across the southeast states with showers and thunderstorms again Sunday afternoon. Instabilities right now look to be slightly lower than Saturday, though still high, with several thousand J/kg. Any activity should weaken fairly quickly with sunset. Monday and Tuesday, the high pressure should become the dominant feature with most of the area remaining rain free each day. A series of thunderstorms will move around the high, with most of the coverage north of the area. The very far northern fringes of central AL could see isolated to scattered convection each afternoon. By Wednesday, a low pressure will develop over the Plains and move east. A frontal boundary with that low will move across the state. The front should be stronger with the low pressure closer to the state compared to the low moving through the Ohio Valley this weekend. Though the wind field is expected to be widespread and moderate. 24 && .AVIATION... (00Z TAFS) Issued at 609 PM CDT WED MAY 14 2025 VFR conditions through 10z, then some low clouds will begin to stream in from the south once again. Look for the clouds to make it to TCL, MGM and EET. There is a low probability that BHM and ASN will see the clouds so left them out for now. Clouds mix out by 15z then VFR conditions prevail, with southwestern winds increasing to 8 to 10 kts. 16 && .FIRE WEATHER... An overall dry trend will be in place through Friday. Minimum RH values will remain in the 40s and 50s this afternoon, with 20ft winds around 6 to 9 mph. Slightly drier conditions on Friday ahead of the next system. Minimum RH values will be the 40s north to upper 30s in the south, with 20ft winds around 7 to 10 mph. Rain enters the area Friday night across the north. && .PRELIMINARY POINT TEMPS/POPS...
