A Severe Thunderstorm Watch is in effect for most of South Central Texas, with storms expected to remain a concern through the night. Forecast guidance points to the highest risk in the Hill Country, while the San Antonio metro area also faces the potential for severe weather.
The Storm Prediction Center has placed parts of the Hill Country and the Austin metro area under a Level 3 risk out of 5. The San Antonio metro area is under a Level 2 risk, which still supports the chance for strong storms tonight.
Storm timing across the region
The most active window varies by location. In the Hill Country, storms are expected from 8 PM Sunday through midnight, while the San Antonio metro area could see storms from 9 PM Sunday to 2 AM Monday.
Some storms may weaken as they move, but others could still become strong to severe. Forecasters are watching for damaging wind gusts, quarter-sized hail, and locally heavy rain that may lead to brief street flooding.
Main hazards and possible impacts
Damaging straight-line winds are the biggest concern, with gusts of 70 mph or greater possible. Winds of that strength can bring down tree limbs, snap trees, and cause scattered power outages.
Heavy rain may also create short-lived flooding in low-lying or poorly drained spots. While exact storm tracks cannot be predicted in advance, the expected setup supports a period of weather that calls for close attention to warnings.
Steps to prepare tonight
Residents are being urged to secure loose outdoor items such as patio furniture, trampolines, and car ports. Vehicles should be moved into a garage when possible, or parked away from trees to reduce the risk from falling limbs.
It is also important to keep phones and other devices charged in case power goes out. A reliable way to receive weather warnings is especially important overnight, when storm activity can develop quickly.
What comes after the storms
The storms are expected to move out quickly, with most areas clearing by early Monday morning. Behind the cold front, conditions should turn quieter and more comfortable.
Monday is forecast to bring slightly cooler temperatures, with highs in the upper 70s to low 80s. Sunshine and dry weather should dominate after that, with a warming trend through the week and highs returning to the 90s by late week.
