The episode as NWS OUN wrote it up.
A slow moving warm front lifted northward during the day, extending across northern and central portions of Oklahoma. Aided by daytime heating, isolated to widely scattered thunderstorms developed along the warm front. With fairly warm and dry surface conditions, spotty damaging winds occurred as thunderstorms collapsed.
