FORECAST

RAINFALL NEXT WEEK

While we expect Monday and Tuesday to be relatively quiet, an approaching storm system, deep moisture, and a slow-moving front will combine to give us a threat for heavy rainfall starting late Wednesday. The timing of this event is coming into focus, however, expect changes in the finer details. Here’s the latest:

  • WEDNESDAY: We expect most of the day to be quiet. But, we will be watching what is unfolding to our northwest. A line or cluster of storms may form and work into the South-Central Texas by Wednesday night. Should any storms form Wednesday afternoon, severe weather would be possible, along with flooding.
Heavy rain could begin Wednesday evening. (Copyright 2026 by KSAT - All rights reserved.)
  • THURSDAY: Our best shot at rainfall. Storms are possible Thursday morning and may linger throughout the day, depending on the movement of a slow-moving front. Early estimations have the highest threat for flooding pinpointed for central portions of Texas. Temperatures will be cooler due to clouds and rainfall.

  • FRIDAY-SUNDAY: It’s possible that rain chances could linger into the weekend. While not as heavy, we’ll continue to watch for any additional flood threat. Otherwise, it will be cooler, with highs staying in the 80s. Again, specifics will need to be ironed out. We’ll continue to update this forecast often. Please check back.
