What happened
The episode as NWS OUN wrote it up.
An upper level storm system closed off over parts of west Texas, and very slowly moved east toward the southern Plains. Disturbances rotating around the system aided in the development of thunderstorms during the late afternoon and evening hours. The storms developed mainly along the dry line that had set up near the Texas panhandle/Oklahoma border, with the cap liming coverage initially during the late afternoon and early evening. However, a line of strong to severe thunderstorms moved out of the Texas panhandle around mid evening, with more widespread reports of large hail and a few severe wind gusts. No damage was reported.
What forecasters said that day
