TUESDAY & WEDNESDAY

Tuesday will play out very similar to Monday, with any storms staying west of San Antonio. That said, any storm that develops along the Rio Grande or in the Hill Country could quickly become strong to severe.

By Wednesday, an upper-level storm system may push showers and storms a little closer to San Antonio. Still, our odds of rain remains fairly low (30%). Temperatures will stay warm.
