| Area Forecast Discussion National Weather Service Houston/Galveston TX 1154pm CDT Fri August 7 2026 ...NewARINE... .KEY MESSAGES... - Scattered seabreeze showers and thunderstorms expected on a daily basis through early next week. - There is a chance of more numerous showers and thunderstorms on Sunday and/or Monday. - Seasonably hot with highs in the 90s and heat index values 101-108F each day. Issued at 1115pm CDT Fri August 7 2026 No major changes to the forecast. Hot weather and daily rain chances can still be expected through early next week. Ridging is currently situated over the Four Corners/off the East Coast. A weakness between both has resulted in lower heigheights & subsidence, which should allow for scattered showers and storms each day into next week. Expect most of this activity to occur during the daytime along the sea breeze, generally across the southern 2/3rds of our CWA. Lowering heigheights and the arrival of deep tropical moisture will bring the highest rain chances on Sunday and Monday. Daytime temperatures throughout the time frame will still be fairly hot, especially in spots that don't receive rainfall, with highs in the 90s and heat indicies in the triple digits. Would be worth practicing heat safety still, especially for those spending extended time outdoors. Patchy fog may develop in spots during the early morning hours. Around Tuesday, 850mb temperatures begin to rise again as ridging builds across the northwestern Gulf. Afterwards, temperatures and heat indicies slowly rise while rain chances decrease. 03 Marine Issued at 1115pm CDT Fri August 7 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 scattered showers and storms will be greatest during the early morning through early afternoon hours for the Gulf. Shower and storm coverage may become more widespread on Sunday and Monday. 03 NOAA Houston/Galveston TX Office: Watches - Warnings - Advisories TX...None. GM...None. |
