We’ll see plenty of sun today! Highs will be in the upper-80s. There is, however, a small window for storms from 4 pm to 8 pm. The chance and coverage stand at about 30%, but if you get a storm, be prepared for heavy downpours, lightning, and perhaps some small hail. If you have outdoor plans, stay weather-aware!

MONDAY

Even less of a rain chance than Sunday. It’ll be mostly sunny and warm with a high near 90°. While there is a small chance (20%) for an afternoon pop-up storm, odds favor it staying dry.

NEXT WEEK

Another low pressure system will move across South Central Texas Tuesday through Wednesday. This will bring our highest chance for widespread rain (60%) Tuesday night into Wednesday morning. Be prepared for the possibility of street flooding after the Spurs game Tuesday and for the Wednesday morning commute. Then, expect a drier and warmer weather pattern to end the week.
