Hail in McIntosh County, Oklahoma

Strong to severe thunderstorms developed over central Oklahoma during the late afternoon of the 24th, to the northeast of a low pressure system over southwestern Oklahoma and near a warm front over central Oklahoma into eastern Oklahoma. Strong instability combined with very strong deep layer wind shear associated with an approaching strong upper level storm system supported the development of some supercells. These storms produced very large hail over central Oklahoma. Thunderstorms developed into eastern Oklahoma during the evening, the strongest of which produced large hail up to quarter size.
