119 FXUS64 KBRO 011730 AFDBRO Area Forecast Discussion National Weather Service Brownsville TX 1230 PM CDT Tue Jul 1 2025 ...New SHORT TERM, LONG TERM, AVIATION, MARINE... .SHORT TERM... (Tonight through Wednesday night) Issued at 1222 PM CDT Tue Jul 1 2025 After a rainy Tuesday, precipitation chances are expected to rapidly drop off tonight as Tropical Storm Barry remnants continue to move out of the region and high pressure begins to settle into the area. Precipitation chances are approximately 20-30% tonight, lowering to 10-20% tomorrow. Tomorrow night, there is little to no chance of showers or thunderstorms as higher pressure moves into the area. High temperatures are still expected to be below seasonal values tomorrow, getting up into the upper 80s/lower 90s, but is the beginning of a warming trend that is expected to continue through the week. Lows will gradually warm from the low to mid 70s tonight to the mid to upper 70s tomorrow night. A moderate risk of rip currents due to lingering Tropical Storm Barry swell is in effect through tonight, and may need to be extended depending on how quickly swell and wave heights come down. && .LONG TERM... (Thursday through next Tuesday) Issued at 1222 PM CDT Tue Jul 1 2025 Conditions are expected to continue drying out throughout the week as upper level ridging continues to move over the area, bringing subsidence and higher pressure to the surface. Skies are expected to clear from mostly cloudy on Thursday to partly cloudy by Saturday, with very little rain chances for the area for the remainder of the week into the weekend. High temperatures are expected to gradually warm from the low to mid 90s on Thursday to the upper 90s by early next week. As the temperatures warm, humidity is expected to somewhat fall, keeping the heat risk fairly consistent (minor to moderate) through the beginning of next week. Winds will remain light to moderate and southeasterly throughout the forecast period. && .AVIATION... (18Z TAFS) Issued at 1222 PM CDT Tue Jul 1 2025 VFR conditions are expected for all airports, but any immediate showers and thunderstorms could drop ceilings and visibilities to MVFR/IFR.
