San Antonio woke up to a sticky start on Saturday, April 11, 2026, with muggy low clouds, temperatures hovering near 70°F, and patchy fog sneaking across the metro. Highs are expected to climb into the low 80s, and scattered showers and thunderstorms remain possible through the day. The main trouble spot, though, looks to be Saturday night, when a line of storms forming over the southern Edwards Plateau could push east toward the Hill Country and the I-35 corridor into early Sunday, bringing heavy downpours and isolated severe gusts. Anyone with evening plans should be ready to duck inside if those storms organize.
Morning Fog And A Slower Commute
Patchy fog and light showers this morning may knock down visibility and put a drag on the commute, with roads turning slick in a hurry where rain bands roll through. East-southeast winds are forecast around 5 to 15 mph, with gusts near 25 mph possible this afternoon and evening. For the latest timing, watches, and any airport impacts, check updates from the National Weather Service Austin/San Antonio.
Evening Line Could Bring Heavy Rain
Forecast discussions and high-resolution models point to a more vigorous wave of storms organizing over West Texas late Saturday and marching east, with the southern Edwards Plateau and Val Verde County likely seeing the heftiest totals. As that cluster congeals, storms could grow more linear overnight, shifting the primary threat to damaging straight-line winds and brief large hail. Locally heavy rainfall may also trigger flash flooding in tighter Hill Country drainages, so it is a good night to have multiple ways to receive warnings and to avoid driving through flooded roads, no matter how familiar the route.
Sunday And Next Week
Sunday, April 12, 2026, keeps the humidity cranked up, with showers and thunderstorms likely across much of the area. Many spots could pick up around a half to three-quarters of an inch of rain, with higher pockets in the Hill Country. The active, muggy pattern looks to linger into midweek, which means daily storm chances and warm nights sticking around for a while.

How To Prepare
Before those evening gusts arrive, secure loose outdoor items that might go airborne in a stiff wind. Keep an umbrella and waterproof shoes handy, and steer clear of driving through standing water, even if it looks shallow. If your plans keep you outside after sunset, line up an indoor backup and keep your phone charged so you can receive warnings and check radar on the go. Staying weather-aware after dark will pay off if the line of storms shows up right on top of your route home.
