| Area Forecast Discussion National Weather Service Brownsville TX 636pm CDT Tuesday Oct 27 2026 Issued at 1205pm CDT Tuesday Oct 27 2026 Today we maintain a 15-45% chance of showers/thunderstorms mainly along and east of I-69C. Rain chances taper off tonight into Wednesday with only an isolated chance of an afternoon shower or thunderstorm. Thursday, rain chances increase again across northwestern portions of the CWA (County Warning Area) due to excess moisture moving into northeastern Mexico and Texas from the remnants of Tropical Storm Vance, currently located off the Mexican Pacific coast. Dry conditions will prevail for the remainder of the forecast period outside of a very isolated afternoon shower or thunderstorm. Temperatures will remain slightly above normal with highs in the upper 80s to low 90s through this weekend with low to mid 90s expected for Monday. At the very tail end of the forecast period there is the potential for a cold front to move though the region which could cool things down a bit. At area beaches there is a High Risk of Rip Currents through this afternoon. In addition, there is a Coastal Flood Advisory in effect until 4 am Wednesday due to the high astronomical tides. High tide is at 7:48pm tonight. Marine Issued at 1205pm CDT Tuesday Oct 27 2026 Favorable conditions will prevail with light winds, seas of 4-5 ft, and 7 to 8 second periods.
