SPC did have this mention from the latest update
Northwest/North Texas and Oklahoma...
A very active severe-weather day is expected including a regional
outbreak of severe storms. The potential exists for very large hail
and a few tornadoes this afternoon, with widespread damaging
winds/derecho potentially developing into this evening and
overnight, especially across much of North Texas and southern
Oklahoma.
