An area of upper level low pressure entered the southwestern United States, with a powerful jet stream moving toward the southern plains. Thunderstorms developed in two waves, one occurred in the morning hours, with stronger thunderstorms developing in the afternoon. A surface low pressure center was located over the Texas panhandle, with a warm front extending southeast into northern parts of Texas. Warm, moist air was located south of this front. The warm front moved north into Oklahoma during the morning hours, with thunderstorms developing over a large part of western Oklahoma. A few thunderstorms briefly became severe during the morning hours as they moved north. Another more significant round of thunderstorms developed in the afternoon as the surface low moved east and a cold front moved through the state. Large hail and damaging winds were observed. The front moved into southeast Oklahoma by early evening, with heavy rainfall developing behind it.
