SAN ANTONIO – As we approach the start of Daylight Saving Time (March 14th) and the official start of spring (March 20th), we’ve been experiencing a warmer, more humid weather pattern.

And as we all know, spring can often mean thunderstorms. In fact, parts of the KSAT viewing area will have a chance to see a few storms Saturday night. Here are the forecast highlights:

  • A strong upper low has moved into the plains Saturday, kicking off a line of severe storms across West Texas. This line will approach our western counties before midnight.
  • A few storms out west late Saturday evening could be strong, with the best chance of severe weather well northwest of our area. Widespread severe weather across South-Central Texas is not anticipated.
