| Area Forecast Discussion ...UPDATED National Weather Service Brownsville TX 1235am CDT Sat April 11 2026 Issued at 1105pm CDT Fri April 10 2026 Showers and thunderstorms remain the primary forecast concern through the weekend as a strong upper level shortwave moves across Northern Mexico and Texas. Precipitation probabilities around 20-30% will likely support isolated to scattered showers with a lower probability of thunderstorms Saturday. The probability of precipitation increases to around 30-40% Sunday as increased forcing along the Sierra Madre Mountains paired with increased instability and ample wind shear will likely result in conditions favorable for the development of strong to severe thunderstorms over Northern Mexico. Convective models are increasingly supporting organized convection approaching Deep South Texas Sunday evening. CAPE values across the area Sunday afternoon into Sunday evening will likely range from 1000-1500 J/kg, though CIN values approaching 150-200 J/kg could hinder convection. The Storm Prediction Center has a Marginal Risk for severe weather across Deep South Texas Sunday. Rain chances are forecast to diminish Monday and remain near zero through the remainder of the forecast. High temperatures are forecast to remain in the 80s through the weekend, gradually warming to the low to mid 90s by mid week. Marine Issued at 1105pm CDT Fri April 10 2026 Favorable marine conditions are forecast to continue Saturday with adverse conditions likely developing Sunday and lingering through much of the week. Stronger southeasterly winds are likely to develop Sunday building moderate seas along the off shore Gulf waters. Small Craft Should Exercise Caution statements may be needed each afternoon next week. NOAA Brownsville TX Office: Watches - Warnings - Advisories TX...None. GM...None. |
