RAIN CHANCES: Small opportunities, mainly Saturday and Tuesday
FORECAST
Sure, temperatures are trending down, but the humidity is trending up. So, in essence, we are trading one bad for another. And in the end, it’s just hot. Because it’ll be sticky, heat index values could reach as high as 105° the next several afternoons (see below).
FRIDAY AND THE WEEKEND
There’s no big changes to the forecast as we head into the weekend. It’ll be hot and humid, but the one small caveat would be a stray storm or two, mainly in the Hill Country. This is especially the case on Saturday, as the dryline may be just enough to stir up a storm or two.
Friday through Sunday will be hot and humid. (Copyright 2025 by KSAT - All rights reserved.)
NEXT WEEK
There are indications that a weak front could will make a run at San Antonio Tuesday into Wednesday, and we’re not gaining confidence in it having a noticeable impact on temperatures and humidity.
