A tornado watch is now in effect until 11 PM CT for portions of the Davis Mountains, Trans-Pecos, western Permian Basin, and the westernmost column of counties in West Texas. We’ll be watching for thunderstorms to develop in southern and southeastern New Mexico along with the Davis Mountains over the next few hours. Those storms will progress northeastward with a threat of tornadoes, large hail, and localized damaging wind gusts. Additional storms will form later this evening and grow upscale into a squall line. Those are the storms that will move eastward and impact the Texas Panhandle, West Texas, Permian Basin, Concho Valley, Edwards Plateau, Hill Country, Big Country, Northwest Texas, and North Texas late tonight and into the morning hours on Wednesday. Damaging straight-line winds, potentially widespread, will be the primary threat. Brief tornadoes are possible as well. See our previous blog updates for more on tonight’s storm chances.
