It appears we’ve survived yet another brutal South Texas summer. Fall doesn’t officially arrive until September 22nd, but long stretches of triple-digit heat look to be in our rear-view mirror. Here’s an overview of what to expect for the rest of this week.

Feeling Like Fall?

  • A cold front will slide into the Hill Country and Edwards Plateau on Wednesday
  • The biggest question is: will the front clear San Antonio?
  • As of Wednesday afternoon, it appears San Antonio could at least get a tiny taste of cooler air by Thursday morning
  • If the front is able to move farther east, it could get even cooler than that with morning lows near 60° Thursday and Friday

Rain Chances On the Rise

  • Regardless of temperatures, rain chances will increase Wednesday as the front approaches
  • With pockets of heavy rain possible, a Flash Flood Watch will be in place through Thursday afternoon for Bexar County and & our Hill Country counties - as seen in the image at the top of this article
  • Around San Antonio, maximum rainfall potential is up to 1.5 to 2.0 inches of rain
  • Near Del Rio, which is experiencing extreme drought, rainfall totals could amount to up to 5 inches through Saturday
  • At the very least, the rain and clouds will help to limit high temperatures Wednesday and Thursday
