San Antonio woke up to a muggy start Wednesday, June 3, sitting mostly cloudy and around 73°F at 4:55 a.m. Dew points near 70°F are keeping the air thick and sticky. Scattered showers and thunderstorms are on the table after 10 a.m., with a high near 89°F and a light east-northeast breeze of about 5 to 10 mph.
Afternoon Storms Could Be Gusty
Any storms that bubble up this afternoon could pack brief heavy downpours, frequent lightning and gusty winds that cut visibility and slow the evening commute. The National Weather Service Austin/San Antonio expects scattered storms across the region today and again Thursday, so it is a good day to keep an eye on radar and build in extra travel time.
Heavier Rain Possible Late Thursday Into Friday
Late Thursday into early Friday, a more organized batch of storms may set up heavier rainfall over the Rio Grande plains and the southern Edwards Plateau before that axis of heavier rain slides east toward the city on Friday, potentially bringing slower-moving storms. Forecast guidance points to showers and thunderstorms likely Friday, with highs backing off into the mid-80s. Localized flooding is possible where storms repeatedly track over the same neighborhoods. See how midweek heat set the stage for this pattern.
What This Means For Your Week
Plan on warm, muggy nights in the low to mid-70s through the weekend, with rain chances slowly backing off but not disappearing as temperatures drift back toward normal. Outdoor events should have a wet-weather backup plan, and drivers need to steer clear of standing water - it only takes a few inches to stall a car. For the latest watches, warnings and live radar, check the National Weather Service and local traffic alerts before you hit the road.
Bottom line: grab an umbrella this afternoon and stay weather-aware through Friday. If you live in a low-lying spot, move important items off the floor and do not try to drive through flooded streets.
