FXUS64 KBRO 252326 AAA AFDBRO Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 626 PM CDT Fri Apr 25 2025 ...New AVIATION... .SHORT TERM... (Tonight through Saturday night) Issued at 141 PM CDT Fri Apr 25 2025 Upper level ridging across the Southern Plains looks to persist through the period. Broad subsidence aloft will likely limit rain chances through the period. Sustained southeasterly low level flow will continue to advect warm, moist air to the region. This will support the development of low stratus clouds overnight, and a very low (<10%) chance for some light showers Saturday morning. Low temperatures tonight and Saturday night are expected to be in the low to mid 70s, with high temperatures Saturday afternoon in the upper 80s to low 90s. && .LONG TERM... (Sunday through next Friday) Issued at 141 PM CDT Fri Apr 25 2025 The subtropical ridge gradually drifts south into mid next week as multiple troughs swing into the Southern Plains. This will maintain southwesterly flow aloft and generally dry conditions across Deep South Texas through Tuesday, with near to slightly above normal temperatures. Shortwaves Wednesday through Friday enhance lift and instability, bringing a low (20 percent) chance of thunderstorms Wednesday and Thursday, mainly across the northern ranchlands and along the Rio Grande in the upper valley. A medium (40 percent) chance of showers and thunderstorms is expected Friday for all of Deep South Texas. Expect breezy to windy conditions each afternoon, especially Monday and Tuesday. Brief Wind Advisories may be needed for the lower RGV Monday and Tuesday. && .AVIATION... (00Z TAFS) Issued at 620 PM CDT Fri Apr 25 2025 All TAF sites are currently sitting with mainly clear skies, aside from a few low clouds over KBRO, along with a moderate southeasterly breeze. Overnight, winds become less breezy and MVFR ceilings are expected to develop as moist low levels develop stratus. Mostly clear skies gradually return throughout Saturday morning as southeasterly winds pick back up to moderate with gusts up to 20-25 knots. && .MARINE... Issued at 141 PM CDT Fri Apr 25 2025 Tonight through Saturday night...Generally favorable marine conditions are expected through the period, however wind speeds on the Laguna Madre may briefly require Small Craft Should Exercise Caution headlines Saturday afternoon. Otherwise light to moderate southeasterly winds and slight to moderate seas are expected for the coastal waters. Sunday through Friday...Moderate to fresh southeasterly winds continue into late next week, with SCEC conditions likely across the bay nearly every afternoon.
