Scattered thunderstorms developed across eastern Oklahoma during the afternoon of the 17th. The air mass across the region was very moist and moderately unstable, allowing the strongest thunderstorms to produce damaging wind gusts. Additional thunderstorms developed during the early morning hours of the 18th. Unusually high moisture content of the air, and slow-moving thunderstorms resulted in locally heavy rainfall and flash flooding.
