Heat and humidity will be a mainstay in the forecast through the foreseeable future. The question will be if all that mugginess leads to some rainfall. Our best chance arrives this evening, with storms that move in from the west.

Here’s what we’re monitoring:


  • Skies stay mostly cloudy, while temperatures warm into the 80s.
  • Around 4-5 p.m., scattered showers and thunderstorms are expected to develop in northern Mexico and move into our far western counties.
Future radar at 6pm. We expect strong to storms to have developed from Del Rio to Eagle Pass. (Copyright 2023 by KSAT - All rights reserved.)
  • These storms could quickly become strong-to-severe, with large hail and strong wind gusts being the main concerns to monitor.
  • This activity will then track east through the evening hours, and depending on how well it holds together, could potentially impact part of the San Antonio area by 8 p.m. - 11 p.m.
Future radar at 10pm. Storms that develop out west will try to work their way east toward San Antonio tonight. (Copyright 2023 by KSAT - All rights reserved.)
  • Whatever is left of the rain and storms should push through our far eastern counties by midnight, leaving much quieter overnight hours.
Severe weather risk for South-Central Texas. Most of the viewing area is within the 'scattered' risk, with hail and gusty winds being the main threats. (Copyright 2023 by KSAT - All rights reserved.)

FRIDAY (5/5)

  • A hot and muggy day will round out the work week, with a high in the upper 80s and more humidity.
  • A few isolated thunderstorms will be possible in the afternoon/evening, and while a low-end risk, could briefly become strong/severe.

THIS WEEKEND (5/6 - 5/7)

  • The biggest theme this weekend will still be the heat and the humidity.
  • Highs are expected to climb to about 90° each afternoon, but added moisture will likely make it feel like the mid-90s.
  • Additional isolated storm chances (~30%) are in the forecast each day, so we’ll keep our eyes on the radar closely.
