What happened
The episode as NWS OUN wrote it up.
A strong upper level storm moved through the central plains into the upper midwest. A dry line extended south from this storm system through Oklahoma. By the late afternoon, the dry line was located from Ponca City, to El Reno, to Lawton. East of the dry line, dew point temperatures were in the lower 70s. A strong cap in place east of the dry line inhibited storm development for much of the afternoon, but isolated thunderstorms developed during the late afternoon and early evening. The thunderstorms mainly stayed below severe limits, but some storms became severe with large hail and heavy rainfall.
