SAN ANTONIO – This week will give us a full spectrum of weather, from fronts to tropical systems to heavy rainfall. We’ll be updating you frequently through our KSAT Weather app as the event unfolds. Here’s what we’re thinking right now:

  • Moisture surges back into the area Tuesday morning. This will lead to a damp commute with light rain possible. Isolated showers and storms are also possible through the day.

  • Tuesday night, a complex of storms will develop west near the Rio Grande and push east overnight, bringing heavy rain for those west of I-35. Storms could be in the San Antonio area by sunrise Wednesday.

  • Wednesday, a front will begin to slowly move into Central Texas. Rain will focus along the front and the best chance of rain during the day on Wednesday will be across the Hill Country and Edwards Plateau.

  • Tropical Storm Pamela, soon to be Hurricane Pamela, has developed in the eastern Pacific. It is forecast to make landfall Wednesday morning on the west coast of Mexico. The quick-moving system will race towards Texas by Wednesday night and into Thursday morning.

  • As the tropical moisture combines forces with the frontal boundary Wednesday night and Thursday morning, heavy rain will become a threat for the area. As of now, the best chance for heavy rain will continue to be across the Edwards Plateau and Hill Country, mainly west of I-35. Still, San Antonio could see healthy rain totals, especially by Thursday morning. In addition, any slight change in Pamela’s path could change where the corridor of heaviest rain sets up.

Potential Rainfall through Friday (Copyright 2021 by KSAT – All rights reserved.)
  • Rain should end west to east on Thursday, as the remnants of Pamela move away.

  • The front will finally surge through the entire area on Friday, bringing a small chance for a few more showers. Behind the front, expect gusty winds, cooler temperatures, and drier air.

  • The weekend looks beautiful. It will be a bit breezy on Saturday, however, it’ll be sunny and highs will only be in the 70s! Overnight lows could dip into the 40s in many spots.
