| Area Forecast Discussion National Weather Service Houston/Galveston TX 1105pm CDT Wednesday August 5 2026 ...NewARINE... .KEY MESSAGES... - Seasonably hot with highs in the 90s and heat index values 100-107F each day. - An isolated late day shower can't be ruled out along the seabreeze in the afternoons. - Slightly better rain chances expected Thursday into early next week for the eastern and southern parts of the region as some deeper moisture flows back inland. Issued at 1105pm CDT Wednesday August 5 2026 Ridging centered over the Southwest CONUS/Four Corners will keep uneventful weather over the region through the better half of next week at least. Heigheights and 850mb temperatures are still expected to drop into the weekend, resulting slightly lower heat stress and surface temperatures. Reduced subsidence and rising PWs should bring better rain chances during this period as well, with isolated to scattered showers and storms possible along the seabreeze/baybreeze each afternoon. Highs remain in the 90s each day with heat indices reaching the triple digits in the afternoon. Some patchy fog will be possible during the early morning hours. 03 Marine Issued at 1105pm CDT Wednesday August 5 2026 Onshore winds 10-15 knots and seas of 2-4 feet are expected throughout the next several days. Rain chances increase slightly through early next week. Chances for isolated to scattered showers and storms will be greatest during the late night through early afternoon hours for the Gulf. 03 NOAA Houston/Galveston TX Office: Watches - Warnings - Advisories TX...None.
