During the morning hours of the 26th, a cold front moved into southwest Kansas, with a dry line extending south of the front into the eastern Texas panhandle. An outflow boundary was located from central Kansas, south into north-central and northeastern Oklahoma. Thunderstorms developed over the Texas panhandle during the afternoon east of the dry line and moved east into western Oklahoma. Other thunderstorms developed along and north of the outflow boundary in north-central Oklahoma.  Thunderstorms became more widespread by evening, as the cold front continued moving southeast. Large hail from golf ball to even softball size, damaging winds to 70 mph, and flooding rains were reported with the severe thunderstorms. Some wind damage was also reported, but there were no injuries. The thunderstorms persisted well into the overnight hours. The thunderstorms finally moved east during the mid-morning hours of the 17th, but left behind several boundaries that helped with severe thunderstorms later in the afternoon. Monetary damages were estimated.
