Houston starts Wednesday partly cloudy, warm and humid, with temperatures near 79 degrees before the city climbs to about 91. Showers and thunderstorms could pop up through the morning and afternoon, and the heat index may reach 102 as southeast winds strengthen.
Wednesday Brings Heat, Wind And Scattered Storms
Rain chances sit near 40% Wednesday, with the best opportunities spread from the morning into the afternoon. Southeast winds will run 10 to 15 mph and could gust to 25 mph, while some downpours may drop a quarter-inch to half an inch of rain.
Thursday turns noticeably wetter, with a 70% chance of showers and thunderstorms and another high near 91. Storm chances remain high Thursday night before Friday brings a likely round of showers and thunderstorms, an 89-degree high and an 80% rain chance.
Heavy Rain Threat Builds Into The Weekend
The wettest stretch may run from Thursday through Sunday, when repeated storms could produce locally heavy downpours. The National Weather Service Houston/Galveston office says widespread rainfall of 2 to 4 inches is possible across Southeast Texas, with higher totals in some areas and a risk of flash flooding.
Saturday looks cooler but stormier, with a high near 85 and an 80% chance of rain. Sunday may top out around 81, with showers and thunderstorms likely; forecasters expect the heaviest-rain focus to shift from the Brazos Valley late this week toward the coast over the weekend.
Outdoor Plans Need A Backup Option
The forecast is a sharper turn from the earlier Hoodline forecast, which focused on heat before the storm pattern strengthened. Anyone driving during repeated downpours should avoid water-covered roads, and outdoor plans should include a quick escape from lightning.
No land-based watches or warnings are listed for Houston, but a Small Craft Advisory remains in effect for portions of the bays and Gulf waters through Thursday morning. Rain chances ease next week, with highs near 81 Monday and Tuesday and a possible cooler, drier shift still being monitored.
