Strong to severe thunderstorms developed across northeastern Oklahoma during the late evening of the 10th and early morning hours of the 11th, as a cold front moved into the area. The strongest thunderstorms produced hail up to penny size, and damaging wind gusts.
Additional thunderstorms developed along and ahead of the cold front during the afternoon and evening hours as it moved into southeastern Oklahoma. The air mass ahead of the front had become very unstable by mid afternoon. This instability, combined with strong wind shear, promoted the development of supercell thunderstorms that produced hail up to golf ball size.
