| Area Forecast Discussion National Weather Service Brownsville TX 1218pm CDT Monday Oct 26 2026 Issued at 1203pm CDT Monday Oct 26 2026 Warm and mostly dry conditions are expected across region this week. A nearby shortwave and increased Gulf moisture will allow for daily low to medium (10-50%) chances of diurnally drives showers and thunderstorms through Wednesday, primarily along and east of I-69C. Thursday, rain chances remain in the forecast, but best chances will be along and west of I-69E due to excess moisture moving into northeastern Mexico and Texas from the remnants of Tropical Storm Vance, currently located off the Mexican Pacific coast. Rain chances taper off late week. Temperatures will remain slightly above normal and slowly climb into the low to mid 90s by this weekend. Overnight lows will be in the mid 60s to low 70s for much of the week, with lows in the 70s by late week into the weekend. Easterly flow across the Gulf increases the threat of rip currents this week. Additionally, astronomical tides will narrow beaches during high tide cycles each afternoon and evening. A Coastal Flood Statement is in effect today from 3pm until midnight and additional Coastal Flood Statements may be needed over the next day or two. Marine Issued at 1203pm CDT Monday Oct 26 2026 Slightly adverse marine conditions are expected today, mainly on the offshore Gulf waters, due to slighlty elevated seas. Otherwise, favorable conditions will prevail with light winds, seas of 4 to 5 ft, and 7 to 8 second periods. Isolated showers and thunderstorms this week could lead to localized areas of increased winds and seas. NOAA Brownsville TX Office: Watches - Warnings - Advisories TX...None. GM...None. |
