The episode as NWS TSA wrote it up.
Widespread thunderstorms developed during the morning of July 9th, south and east of a stationary frontal boundary that was located across eastern Oklahoma and southern Missouri. Thunderstorms reorganized during the early afternoon on outflow from previous thunderstorms as a mesoscale convective vortex drifted across the region. Some of the storms strengthened and became organized, producing damaging wind and a tornado. Flash flooding also occurred across portions of eastern Oklahoma.
