We're expecting storms to develop tonight near the border then organize and push toward San Antonio into Sunday morning.
Some storms could be severe with localized hail, up to 2.5 inches, and wind gusts up to 70 mph.
The active weather should move out of the San Antonio area by the early afternoon tomorrow.
Adam Caskey will be standing by in the KSAT-12 Weather Center and Justin Horne will be deployed in the Storm Chaser to cover the latest developments.
