San Antonio Braces For Severe Storms After Record Heat Wave

San Antonio Braces For Severe Storms After Record Heat Wave...

San Antonio faces a dramatic weather shift today as severe thunderstorms threaten the region following days of record-breaking heat. The National Weather Service issued a severe weather alert early Saturday, warning of potential hail, damaging winds, and isolated tornadoes through Sunday evening.

Temperatures soared to 98°F earlier this week—nearly 15 degrees above average for late April—before a cold front triggered the storm system. Local meteorologists report the unstable conditions resulted from extreme heat colliding with cooler air moving south from the Plains.

The sudden shift has residents scrambling. Home improvement stores reported surges in generator and sandbag sales Friday, while CPS Energy crews are on standby for potential outages. Several outdoor events, including Fiesta San Antonio activities, have been postponed or moved indoors.

Flash flooding poses particular concern in low-lying areas near the San Antonio River and Salado Creek. The city activated its emergency operations center Saturday morning, coordinating with first responders and school districts.

This weather whiplash comes as climate scientists warn of increasing volatility in Texas weather patterns. San Antonio has experienced seven 100°F+ days already this year—the earliest occurrence on record.

Residents are advised to secure outdoor items, avoid travel during peak storm hours (3-9 PM Saturday), and monitor local alerts. The storms are expected to move east toward Houston by Monday morning, leaving cooler temperatures in their wake.
