FORECAST
FRIDAY
Another warm day with a sun/cloud mix and the off chance of a few afternoon storms, but odds are against much if anything from developing. Plan for highs in the mid 80s.
WEEKEND
Storms should hold off until after 2pm Saturday with the chance of storms becoming severe. Flash flooding/street flooding will be a possibility through Sunday morning. (Copyright 2024 by KSAT - All rights reserved.)
A front will move north to south across the area on Saturday, reaching San Antonio by the late afternoon and evening hours. As it moves through, it’ll kick up showers and storms. We likely reach the 80s before the front arrives. Storms that develop along the boundary will have the potential to be strong or severe. Hail and gusty winds would be the main threats.
Storm chances peak Saturday night, with widespread rain. It’s during this time that we’ll need to monitor for street flooding. If you can, it’s best to stay off of the roads Saturday night or avoid low water crossings.
