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 Labor Day weekend and next week.

Healthy rainfall returns

  • Scattered showers and storms stay in the forecast through Saturday evening
  • Localized heavy rainfall is possible, with minor street flooding in spots
  • Severe weather is not anticipated, but frequent lightning and gusty winds will be fairly common with any storms that develop
  • There will be periods of sunshine mixed in with the mostly cloudy conditions

A hot Sunday & Labor Day

  • Our weather pattern is forecast to quiet down Sunday through Tuesday, meaning chances of rain will be ’slim to none’ for a couple of days
  • Expect partly cloudy skies on Labor Day, with highs in the mid-90s
  • Heat index values could approach 100° in the afternoon

Potential front next week

  • As of Saturday night, forecast confidence was growing to support the arrival of that cold front by the middle of next week
  • Rain chances will pick up significantly by Wednesday as the front approaches South Texas
  • Cloud cover and rainfall would help to keep temperatures down, potentially resulting in a high only in the 80s on Wednesday
  • Behind the front, it will become cooler and drier
  • Mornings will be pleasantly crisp Thursday, Friday, and Saturday, while afternoon will be comfortable with highs in the 70s and 80s
