What happened
The episode as NWS OUN wrote it up.
The front that pushed through Oklahoma on the first remained just south of the Red River. Moisture streaming over the front allowed for thunderstorms to develop during the early morning hours, eventually forming into a large complex. Another area of thunderstorms, with isolated severe thunderstorms, developed during the mid to late afternoon hours as an upper level disturbance moved east out of the Texas panhandle. The second round of thunderstorms was mainly confined to the southeast part of the state.
What forecasters said that day
