Thunderstorms developed along a warm front located over southern Kansas. Two lines of thunderstorms moved south into Oklahoma during the evening and overnight hours. Both lines produced large hail and damaging winds as they moved through much of the western half of the state. Most of the severe weather reports were hail early in the event, with a transition to more high wind reports later. Winds were measured over 70 mph at several locations. No damage was reported with the thunderstorms.
