FORECAST
There is a chance for isolated rain each day this week. (Copyright 2025 by KSAT - All rights reserved.)
It’ll be a week of small rain chances, but there’s a few important points to know. Not everyone will see rainfall. It’ll be a like playing the “rainfall lottery”. You’ll have to get lucky. Also note that the downpours will likely be brief. That means flooding is not likely and outdoor activities will only briefly be interrupted.
TOMORROW THROUGH THURSDAY
Tuesday will be warm and humid with a chance for an afternoon downpour (Copyright 2025 by KSAT - All rights reserved.)
Humidity isn’t going anywhere, but at least temperatures continue to behave themselves. Highs will only reach the low-90s, while heat indices will come up just short of 100°.
Small disturbance kick up small rain chances this week. (Copyright 2025 by KSAT - All rights reserved.)
Rain chances bump up slightly tomorrow through Thursday. That’s because we’ll have some weak disturbances rolling in from the Gulf of Mexico. Still, chances sit at only 30%.
