Strong to severe thunderstorms developed over northeastern Oklahoma and southwestern Missouri during the evening of the 9th, along and ahead of a cold front that was moving into the area from the north. A moderately unstable air mass ahead of the front, coupled with strong deep layer wind shear, supported the development of supercell thunderstorms. These storms moved southeast across northeastern Oklahoma, and then evolved into a line of thunderstorms across east central Oklahoma. The strongest storms produced hail up to tennis ball size and damaging wind.
