Severe thunderstorms developed across central Oklahoma during the afternoon of the 10th, along a cold front that was moving into the area. These storms moved eastward and across eastern Oklahoma during the evening. In response to a strong upper level disturbance translating into the Southern Plains, wind fields as well as wind shear strengthened considerably during the evening across eastern Oklahoma ahead of the approaching thunderstorms. The very strong wind shear combined with moderately strong instability that existed across the area, resulted in some supercell thunderstorms, as well as the eventual evolution of a squall line. One of the supercells produced a tornado, and the squall line produced several tornadoes as it moved through eastern Oklahoma. Large hail up to two inches in diameter, and damaging wind gusts also occurred from these thunderstorms.
