Thunderstorms developed across north central Oklahoma and south central Kansas during the early morning hours of the 13th, as a low level jet strengthened across the region. Moderately strong instability combined with strong deep layer wind shear to produce severe thunderstorms with large hail up to golf ball size and damaging wind gusts. In addition, slow moving storms that moved repeatedly across the same area resulted in locally heavy rainfall and localized flash flooding.
