FORECAST
WEDNESDAY
Wednesday will be similar to Tuesday (Copyright 2025 by KSAT - All rights reserved.)
Expect a day very similar to Tuesday. We’ll start off muggy and in the 70s. The high will be in the low-90s. After 2 pm through sunset, there’s the chance for a passing shower or storm.
AVOIDING THE EXTREME HEAT
It'll be hotter in areas northeast of Texas. (Copyright 2025 by KSAT - All rights reserved.)
While it is hot and sticky, we have been lucky enough to avoid the ‘heat dome’. It currently sits along the East Coast, where temperatures will be dangerously hot this afternoon. It’s worth noting that San Antonio will be cooler than most of the major cities in the Northeast.
CONSISTENCY
Through the weekend, you won’t see much change to the forecast. Heat, humidity, and a few showers continue.
