A severe thunderstorm watch is now in effect for West Texas south into the Permian Basin. Plainview, Lubbock, Brownfield, Lamesa, Andrews, Big Spring, Odessa, Midland, Fort Stockton, and Alpin are a few of the towns included. The strongest storms this afternoon and this evening may produce very large hail up to the size of tennis-balls, localized wind gusts up to 70 MPH, and isolated tornadoes. Most storms will be producing heavy rainfall. Isolated flash flooding is possible, especially in areas who have already received heavy rainfall in the last few days.

Scattered thunderstorms are developing across the aforementioned regions east of the dryline. We also have storms underway in the Concho Valley and Big Country. The strongest of those storms will also be capable of producing large hail, localized damaging wind gusts, and isolated flash flooding. They’re slowly moving east.

Finally, isolated severe storms remain possible this afternoon in Southeast Texas. Hopefully, we’ve rounded the bend in terms of the tornado threat for the afternoon there.

18Z Simulated weather radar from 5 PM this afternoon through the night. This is only a simulation.

We expect additional thunderstorms to materialize by the evening across West Texas, the Permian Basin, and eventually southeast into the Edwards Plateau. That activity is forming as a piece of upper-level lift slowly moves east across Texas. We’ll probably see one or two thunderstorm clusters that’ll move east tonight into the Big Country, Concho Valley, North Texas, Central Texas, South Texas, and most regions east of there by morning. The strongest storms will be capable of producing damaging straight-line winds, hail, and heavy rainfall. Isolated flash flooding is expected. Not everyone will get rained on tonight and not all storms will be severe. However, most storms will produce dangerous cloud to ground lightning (by definition, a thunderstorm) along with heavy rainfall.
