San Antonio is rolling into Thursday, under a blanket of clouds and Gulf moisture, with early morning temperatures parked in the low 70s. There is a slight chance of a fast-moving shower before 9 a.m., but otherwise skies should stay mostly cloudy while the afternoon high climbs to around 86°F. Southeast winds will crank up later in the day, with gusts near 30 mph that could jostle anything left loose in the yard, according to the National Weather Service.
Afternoon Winds Pick Up
Through the afternoon, southerly to southeasterly winds are expected to run about 10 to 15 mph, with occasional gusts pushing close to 30 mph. Those bursts of wind can turn umbrellas into kites and send lightweight patio furniture scooting across the deck, so it is worth securing or stowing anything that is not tied down before you head out. Drivers should be ready for brisk crosswinds on exposed bridges and highway ramps during the evening commute, as reported by the National Weather Service.
Weekend Rain And Flood Risk
Rain chances start to increase on Friday, March 6, then really ramp up Saturday, March 7, into Sunday, March 8, as a stalled front teams up with several passing disturbances to fire off rounds of showers and thunderstorms. Many spots around the area could see at least an inch of rain, with some locations picking up several inches, a recipe that raises the risk of urban and small-stream flooding, according to the National Weather Service Austin/San Antonio. If you have outdoor plans this weekend, keep them flexible and keep an eye on changing conditions.
How To Prepare
Bring loose outdoor furniture and decorations inside, budget extra travel time when the rain moves in, and remember the basic rule for flooded roads: never drive through standing or flowing water. For maps of flood-prone streets and practical preparedness advice, check the City of San Antonio flood information. Behind the front, expect a noticeable cool-down, with highs dipping into the low 70s on Sunday before temperatures start to moderate again early next week.
