FXUS64 KBRO 152248 AAA AFDBRO Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 548 PM CDT Wed Apr 15 2026 ...New AVIATION... .KEY MESSAGES... Updated at 543 PM CDT Wed Apr 15 2026 Key Messages: - Breezy conditions continue each afternoon through Friday. - A moderate risk of rip currents will likely prevail through the week. - Moderate to high chance (60-80%) of rain this weekend in association with a cold front moving through Texas. - Coastal and marine hazards are expected this weekend behind a cold front. && .DISCUSSION... Issued at 127 PM CDT Wed Apr 15 2026 Little change to the forecast through early this weekend. High pressure to our east continues to maintain warm, dry, and breezy weather through Saturday morning. Above average temperatures with highs around 90 (upper 70s-80s near the coast) and morning lows in the low 70s through Saturday. Breezy southeasterly winds will continue, with gusts around 35 mph possible each afternoon. Gusts are expected to peak on Friday. These should stay below Wind Advisory criteria, but Friday in particular will continue to be monitored. At local beaches, there is a Moderate Risk of Rip Currents through at least Thursday. Gusty winds in conjunction with a new moon this Friday will likely keep the risk elevated through the week. A cold front expected to sweep through deep South Texas late Saturday into Sunday will bring cooler temperatures and be able to tap into the anomalously high moisture content brought about by persistent southeasterly flow. Rain chances increase late Saturday evening through Monday, with thunderstorms possible. Coastal troughing behind the front may continue light stratiform rain through Tuesday. The greatest chance of rain and thunderstorms at this time is from midnight Sunday to Sunday night, with moderate to high chances (60-80%) region wide - highest chances along the upper RGV. Early rainfall amounts are still uncertain, but most likely around 0.5-1.0" between Sunday and Monday. Check back for updates as we continue to refine the forecast. && .AVIATION... (00Z TAFS) Issued at 543 PM CDT Wed Apr 15 2026 Southeasterly onshore winds of around 15-20 knots, gusting to 25-30 knots, this evening are expected to diminish to 10-15 knots with gusts to 20 knots within a few hours beyond sunset, allowing for MVFR ceilings to settle across all terminals overnight. Will continue to monitor for probabilities of IFR and adjust the TAFs as needed. VFR and breezy conditions resume by mid-morning Thursday, becoming gusty again in the afternoon, with gusts to 25 knots and higher. && .MARINE... Issued at 127 PM CDT Wed Apr 15 2026 A moderate to fresh onshore breeze maintains moderate seas into this weekend. An enhanced pressure gradient will bring periods of strong gusts on the Laguna Madre and nearshore Gulf waters out to 20 nm. This will likely result in Small Craft Exercise Caution headlines today and tomorrow afternoons, with brief gusts around 20 kts possible over the Laguna Madre. Flow increases Friday, leaving Small Craft Advisory conditions possible on the Laguna Madre in the afternoon. This weekend, Small Craft Advisory conditions are likely for all lower Texas waters in the wake of a cold front. Expect strong northeasterly flow with near-gale force gusts and rough seas Sunday into Monday. There is an increased chance of rain and thunderstorms Saturday night through Monday. && .PRELIMINARY POINT TEMPS/POPS...
