Austin, Texas – Central Texas will swelter under triple-digit heat Thursday, with afternoon highs reaching 100 to 102 degrees and “feels-like” temperatures climbing as high as 108. The National Weather Service in Austin-San Antonio warned residents to stay hydrated, limit outdoor activity, and take breaks in air conditioning as the dangerous heat peaks in the afternoon hours.
According to the weather service, the heat dome begins to break Friday as scattered thunderstorms return. Rain chances increase to 40–60% across Austin, San Antonio, and the Hill Country this weekend, with the highest likelihood of downpours Saturday night into Sunday. Some storms could bring gusty winds and locally heavy rainfall, raising the risk of isolated flash flooding in low-lying and urban areas.
Travelers along I-35 from Georgetown to San Antonio and U.S. 281 through Fredericksburg should watch for reduced visibility and ponding on roads if heavy downpours develop. Emergency managers urge residents to avoid driving through flooded roadways and to prepare for shifting outdoor event plans.
The unsettled pattern continues into early next week, with daily rain chances and highs dropping into the upper 80s and low 90s.
