==Storm history==
On the morning of May 22, 1981, winds moving in from the south brought moist air across Texas and into western Oklahoma and dry line formed across the Texas panhandle. In addition, the interaction between a layer of warm air aloft and the return flow of moist air led to widespread low clouds across the state of Oklahoma. Later that day, the low clouds broke as predicted by forecasters as the dry line moved east into western Oklahoma. However, the clearing was limited to a relatively narrow zone ahead of the dry line. Despite this, daytime heating allowed thunderstorms to form by mid-afternoon.〔
