571 FXUS64 KBRO 241756 AFDBRO Area Forecast Discussion National Weather Service Brownsville TX 1256 PM CDT Sun Aug 24 2025 ...New DISCUSSION, AVIATION, MARINE... .DISCUSSION... Issued at 1221 PM CDT Sun Aug 24 2025 A weak upper level disturbance will continue to support daily 30-50% rain chances through Wednesday. Upper level ridging looks to strengthen across Texas through the later half of the work week, leading to increased subsidence and lower rain chances. Rain chances look to increase again next weekend as another weak disturbance approaches the area. && .AVIATION... (18Z TAFS) Issued at 1221 PM CDT Sun Aug 24 2025 Predominantly VFR conditions are expected through the forecast. Another round of isolated to scattered convection is expected this afternoon, though the reduced spatial coverage today will likely lower the probability of any impacts at TAF sites. MVFR to IFR visibility reductions could develop if any showers or thunderstorms does move over an airfield. Rain chances are expected to diminish overnight, with VFR conditions likely persisting through mid morning. By late morning or early afternoon Monday, another round of showers and thunderstorm will be possible. && .MARINE... Issued at 1221 PM CDT Sun Aug 24 2025 Generally favorable marine conditions are expected to prevail through the forecast. High pressure across the western Gulf will support light to moderate winds and slight seas through the period. Daily 40-50% chances of showers and thunderstorms are expected through Wednesday, which may locally enhance winds and seas. && .PRELIMINARY POINT TEMPS/POPS...
