Thunderstorms have developed across far East Texas. Some of those storms may produce gusty winds and small hail as they move southeast. Those are more of the ‘summer popup’ variety and not related to an organized severe weather threat.

A severe thunderstorm watch is in effect until 10 PM CT for the Trans-Pecos and far Southwest Texas. Sanderson, Alpine, Marfa, Valentine, Van Horn, Pecos, Fort Stockton, Pecos, Monahans, Kermit, and Dell City are a few towns included. El Paso and Fabens are not included in this watch. The strongest storms may produce very large hail exceeding the size of a baseball, localized damaging wind gusts up to 70 MPH, isolated flash flooding, and perhaps a brief tornado.

Isolated to scattered thunderstorms should begin developing shortly on the higher terrain of the southern Trans-Pecos. Like the last few days, these storms could quickly become severe with a threat of very large hail. Those storms will generally move east/northeast around 20 to 30 MPH. Not all storms are going to be producing destructive hail, but some may certainly be capable of dropping nasty hail.

Thunderstorms will likely grow upscale into a cluster or small squall line by the early evening hours as they move toward the Permian Basin and portions of West Texas. Localized damaging wind gusts, large hail, and isolated flash flooding are expected with the most intense storms through the late evening hours. Unlike yesterday most of this activity should remain across the western third of Texas through the evening and late night hours.
