San Antonio started Saturday, May 9, under a blanket of fog and mist that cut visibility at the airport and left the air feeling thick, with temperatures parked in the mid‑70s. Forecasters say the fog should lift by mid‑morning, giving way to mostly sunny skies this afternoon and a high near 886F. There is only a slight chance of a stray shower in a few spots, so most daytime plans should stay on track.
Weekend Snapshot
Sunday, May 10 is expected to be the hotter half of the weekend, with highs near 916F and a light south‑southeast breeze through the afternoon. Most of the day looks dry, but a frontal boundary is set to move in late Sunday and push rain chances up overnight into Monday, May 11. If you are planning evening outdoor plans, you may want a backup option, according to the National Weather Service Austin/San Antonio office.
Storms Late Sunday Night
Showers and thunderstorms are likely late Sunday evening into the pre‑dawn hours of Monday, May 11, with the main window running from about 7 p.m. Sunday through the overnight period. The Storm Prediction Center places parts of south‑central Texas under a Marginal to Slight risk for severe storms, with large hail and damaging wind gusts the main concerns. Timing and coverage could still shift, so keep an eye on updates and check the Storm Prediction Center convective outlook for details.
What This Means For Commutes
Wet roads and localized downpours could slow down Monday morning commutes. The forecast calls for north‑northeast winds Monday at 10–15 mph, with gusts up to 25 mph and a high near 846F. If you are driving Sunday night, be ready for sudden gusts and reduced visibility in heavy rain, give yourself extra time and avoid any flooded stretches of roadway.
Prep Tips
Before Sunday night, secure patio furniture, keep an umbrella or rain jacket close by, and make sure your devices are charged in case of power outages. If severe weather moves in, head indoors and follow any watches or warnings issued by the National Weather Service.
