The episode as NWS OUN wrote it up.
A thunderstorm complex that had developed over the Texas panhandle weakened considerably as it moved into western and northwest Oklahoma. A heat burst, with a prolonged period of wind gusts of 45 to 55 mph occurred on the fringes of the dissipating storm complex. The wind event affected a large area of western and northwest Oklahoma. A few wind gusts exceeded severe limits, although no damage occurred with the gusts.
