San Antonio, Texas – Scattered storms could rattle parts of Central and South Texas late Saturday, with the greatest risk hitting the Hill Country and Edwards Plateau before weakening near the I-35 corridor tonight.

The National Weather Service in Austin-San Antonio says isolated to widely scattered thunderstorms are expected to develop this afternoon across the Rio Grande and southern Edwards Plateau. The activity will shift eastward through the evening, potentially impacting towns like Del Rio, Kerrville, Fredericksburg, and eventually metro areas like Austin and San Antonio between 5 and 11 p.m.

While not everyone will see storms, those that do could face large hail, damaging wind gusts, brief heavy rainfall, and even a low chance of isolated tornadoes. A Level 2 out of 5 severe weather risk is in place across the southern Edwards Plateau, dropping to a marginal risk as storms move east.

Storm timing varies by region:

  • 3–7 p.m. for western zones including Del Rio and Eagle Pass
  • 5–9 p.m. for central areas including Kerrville, Uvalde, and Fredericksburg
  • 7–11 p.m. for I-35 cities like San Antonio, New Braunfels, and Austin

Residents are urged to stay weather-aware, especially if outdoors this afternoon and evening. NWS recommends having multiple ways to receive alerts, including NOAA Weather Radios and mobile app notifications. Power outages or downed tree limbs are possible in the strongest cells.

Though the risk isn’t widespread, the scattered nature of the storms means localized severe impacts could occur with little advance notice. It’s the kind of setup where “most miss it, but a few get hit hard.”

Storms are expected to fizzle out late tonight as they approach the eastern edge of the NWS Austin-San Antonio forecast area. No additional watches are in effect yet, but updated advisories could be issued by early evening.
