I wanted to take a brief moment to compile the latest timing information for those curious about the timing of the squall line tonight into Wednesday morning. We continue to anticipate a line of strong to severe thunderstorms moving eastward across the Texas Panhandle, West Texas, Permian Basin, Northwest Texas, Big Country, Concho Valley, Edwards Plateau, North Texas, and Central Texas tonight and into the morning hours on Wednesday. Damaging straight-line winds of 60 to 75 MPH are expected with the strongest segments of the line. Given very strong wind shear values, brief tornadoes cannot be ruled out. Some storms this evening may produce hail, but that threat will decrease as the squall line moves east overnight.

Heavy rain is also expected given high moisture values in place. We haven’t had a significant wind damage threat with an overnight squall line in a while, so we’ll be paying attention and providing severe weather updates overnight and into Wednesday morning. Remember that it doesn’t matter if wind damage is produced by a brief tornado or straight-line winds – the end result in the same. We’re especially concerned for those who might be outdoors camping or otherwise unaware of the overnight severe weather threat.
