A Severe Thunderstorm Watch has been issued for the Concho Valley, Hill Country, and Southwest Texas until 11 PM tonight. This includes Sanderson, Del Rio, Hondo, Junction, San Angelo, Abilene, and Brownwood. Isolated storms are expected to develop over the next few hours. A moderately unstable airmass and marginal wind shear values will support a semi-mixed convective mode. A few of the stronger storms may become supercellular for a few hours through the early evening hours. The strongest storms through this evening could produce hail up to the size of tennis-balls, localized wind gusts up to 75 MPH, and localized flash flooding. The threat for a brief tornado is very low. Storms could grow into clusters this evening and progress east/southeast with a damaging wind threat before weakening late tonight.
