San Antonio rolled into Friday, March 6, 2026, under cloudy, muggy skies, with temperatures lingering in the low 70s and a south-southeast breeze already in play. The city will warm into the mid 80s with a high near 84°F and about a 30% chance of brief rain showers this afternoon. Gusts could reach around 25 mph, which will make it feel even warmer and may be enough to send unsecured patio furniture and umbrellas sliding across the yard, according to the National Weather Service.
Rain chances jump sharply Saturday, March 7, and Sunday, March 8, as a stalled front teams up with several disturbances. The National Weather Service is calling for multiple rounds of showers and thunderstorms, with many spots seeing a 60 to 90% chance of at least 1 inch of rain. Areas north of I-10 have a 40 to 60% chance of 2 inches or more, which raises the risk of urban and small-stream flooding. Forecasters also note the potential for strong to marginally severe storms on several days, mainly from large hail and damaging winds.
Afternoon Winds Pick Up
Southerly winds will run around 10 to 15 mph this afternoon, with gusts near 25 to 30 mph in exposed neighborhoods and along the I-35 corridor. Those gusts can flip umbrellas and lightweight furniture, so it is a good idea to secure or stash anything that is not tied down before the afternoon breeze strengthens. Drivers should be ready for brisk crosswinds on bridges and open ramps during the evening commute.
Weekend Outlook
Showers and thunderstorms become more likely Saturday night into Sunday, with the heaviest and most widespread rain expected Saturday night. Periods of heavy downpours could bring a quarter to a half inch of rain on Saturday, with multiple inches possible over the full weekend. For background on how the pattern has evolved and what that means for travel, see how this stormy one-two punch took shape. Keep outdoor plans flexible for March 7 to 8 and build in extra time for any trips through low-lying areas.
Staying Safe
If you find standing water in the road, turn around and do not try to drive through it. Even shallow flooding can hide road damage or stronger current than you expect. Have a way to receive warnings, check forecasts before heading out, and consider moving outdoor events under cover during the Saturday to Sunday window. If you rely on transit or have appointments, plan alternate routes and extra travel time to get around any delays caused by heavy rain or flooded streets.
