What happened
The episode as NWS OUN wrote it up.
The absence of a strong cap, combined with hot afternoon temperatures, and the presence of a departing upper level storm system allowed for thunderstorms to develop over Oklahoma. Strong winds were the main threats with the thunderstorms, with a few areas reporting minor wind damage. The storms moved off to the east and weakened with the loss of daytime heating.
