784 FXUS64 KBMX 301048 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 548 AM CDT Sat Aug 30 2025 ...New AVIATION... .SHORT TERM... (Today through Sunday) Issued at 125 AM CDT SAT AUG 30 2025 Light showers are continuing across the far southern portions of the area early this morning near a remnant moisture axis. There is a noticeable moisture gradient across the area with dewpoints in the upper 50s to lower 60s across the northern half of the area and in the lower 70s across the southern half of the area where some patchy fog may develop through the pre-dawn hours. Expect the drier air to advect south today confining rain chances to our southeastern counties with mostly cloudy skies expected elsewhere. It will be one of the warmer days we`ve had all week, and temperatures will range from near 90F west to near 80F east. A surface high is centered over the Great Lakes region with broad 500mb ridging centered over the Western CONUS. Northwest flow aloft with easterly sfc flow will continue on Sunday as the remnant boundary along the Gulf Coast finally pushes further south. Dry and partly cloudy conditions are expected with highs in the 80s and lows in the 60s. 86/Martin && .LONG TERM... (Sunday night through next Friday) Issued at 125 AM CDT SAT AUG 30 2025 Below average (but still warm) temperatures are expected to continue into next week with the pattern characterized by somewhat of an omega block centered over the Desert Southwest. Rain chances will be influenced early in the week by a low-level shortwave feature embedded within the northwest flow which will track from the Upper Plains towards the Midsouth region by Tuesday. We could see some showers across the northern part of the forecast area during this time, but most of Central Alabama will remain dry. Rain chances will increase area-wide by the middle of the week as the shortwave moves across the region. PoPs are currently around 30-40%, but could increase once the timing of this disturbance is narrowed down. Models are still depicting a more organized trough and frontal passage by the end of the week which will help to reinforce the unusually "cool" and drier airmass that we`ve been experiencing over the last week. 86/Martin && .AVIATION... (12Z TAFS) Issued at 545 AM CDT SAT AUG 30 2025 Some terminals have fallen to MVFR or IFR cigs and vis this morning, although this conditions haven`t been persistent at any one site. All sites should be back to VFR by late morning, although MVFR cigs may hold on at MGM and AUO until around midday. Have included PROB30 for -SHRA at MGM and AUO this afternoon before 00z. Rain chances at the other terminals are not enough to mention. Otherwise, sites should remain VFR from the afternoon through midnight tonight. 12 && .FIRE WEATHER... MinRH values will range from 40-45% in the north and 65-75% in the southeast today. The drier air will gradually advect southward during the day, but some passing showers will continue across the south. Dry conditions are expected through the beginning of the week, but another disturbance will bring rain chances to the area by midweek. Winds will remain relatively light from the east- northeast over the next couple of days. There are no fire weather concerns at this time. && .PRELIMINARY POINT TEMPS/POPS...
