San Antonio woke up Friday, April 10, 2026 to a cloudy, muggy start, with temperatures hovering near 68°F and a southeast breeze around 5–10 mph. Scattered showers and a few thunderstorms are on the table through the morning and into the afternoon, with highs expected to top out near 80°F. Any storm that pops up could bring brief, heavy downpours that cut visibility and leave roads slick in a hurry.
Afternoon Commute
Forecasters at the National Weather Service Austin/San Antonio are calling for roughly a 50% chance of showers and thunderstorms from midday into the evening, with most spots seeing about a tenth to a quarter of an inch of new rain. A few stronger cells could kick up gusty winds and dump heavier rain, and if storms keep rolling over the same neighborhoods, some isolated pockets could see 1–3 inches. Plan on giving yourself extra time for the drive home, and keep the umbrella and a fully charged phone close by.
Weekend And Next Week
Saturday, April 11, 2026 is shaping up similarly warm and unsettled, with a high near 81°F and east-southeast wind gusts up to 25 mph possible in the afternoon. The higher-end risk for stronger storms arrives Sunday, April 12, 2026 into Sunday night, when forecasters say the setup could support large hail, damaging winds and locally heavy rain capable of producing isolated flash flooding. The active pattern may hang around into Tuesday and Wednesday (April 14–15, 2026); for a bit of background on how this pattern has been developing, see our March coverage on the muggy midweek setup.
Plan Ahead
Before evening storms roll in, secure loose outdoor furniture and move anything sensitive indoors so it does not end up in the neighbor’s yard. Never drive through standing water, and remember the old line: turn around, don’t drown. Make sure your phone is set to receive local weather alerts, and have a simple backup plan to move outdoor events inside if storms organize on Sunday. If you live toward the Hill Country or western counties, be ready for brief hail and stronger wind gusts inside any more intense cells.
Quick Forecast
Today (Friday, April 10, 2026): High near 80°F with scattered storms and about a 50% chance of rain, then a low near 68°F tonight. Saturday (April 11) stays warm, unsettled and breezy with gusty southeast winds, and Sunday (April 12) brings the higher chance for stronger storms and heavier downpours. Midweek (April 13–15) trends warm with highs in the mid 80s and lingering storm chances, so keep an eye on updates if you have outdoor plans.
