A severe thunderstorm watch has been issued for portions of the Texas Hill Country and southern Edwards Plateau. Sonora, Junction, Kerrville, Boerne, Fredricksburg, and Kingsland are a few towns included. This watch runs through 11 PM this evening. It does not include Interstate 35, Austin, or San Antonio metro. The strongest storms moving into this watch may produce very large hail, localized damaging winds, frequent cloud to ground lightning, and isolated flash flooding.
Storms moving into the Edwards Plateau this evening may originate from storms ongoing farther west – and from a few storms in northern Mexico this evening. These storms are generally moving east around 20 to 30 MPH. The strongest storms may produce very large hail, localized damaging wind gusts, heavy rainfall, and perhaps an isolated tornado. Storm intensity and coverage should decrease later this evening as we start losing daytime heating. However, we could have a few severe storms continue past midnight in the Edwards Plateau.
Farther to the west in the southern Trans-Pecos, a few severe storms with large hail continue around Alpine. Those will continue for a few more hours as well. Outside of the aforementioned regions we’ve had more typical summer-time popup storms impact Southeast Texas this afternoon. Those storms have produced locally heavy rainfall and some small hail.
