TODAY
Once again, we’re starting with clouds and some patchy fog/haze. If you’ve been waiting to do yardwork, today’s a good day -- especially before noon when it’ll be cloudy. By the afternoon, we’ll have some sun and temperatures will climb to near 90°. With high humidity, it’ll feel closer to 100°.
A very small chance for a severe storm today. (Copyright 2026 by KSAT - All rights reserved.)
The wildcard today is what we’ve been dealing with the last couple of days: A stray severe storm. A “cap” on the atmosphere should limit storm development. The “cap” acts as a weak lid on the atmosphere. If the “cap” breaks, then a storm producing large hail is likely. The chance of the “cap” breaking from 3 pm to 8 pm is about 20%.
THROUGH WEDNESDAY
Similar weather day-to-day with cloudy mornings and hot, sunnier afternoons. We’ll carry a small chance (20%) for a severe storm each afternoon from 3 pm to 8 pm.
THURSDAY & FRIDAY
A slow-moving cool front will push through South Central Texas. This will drop temps into the 80s with higher rain chances (30%-40%).
WEEKEND
Much cooler! Mornings will be in the 50s with highs only in the 60s & 70s.
