The episode as NWS TSA wrote it up.
Unseasonably warm and moist air spread into the region ahead of a very strong cold front that moved into northeastern Oklahoma during the late afternoon hours of the 24th. Thunderstorms developed ahead of the front in this moist and unstable air mass, several of which produced large hail. Thunderstorms moving repeatedly over the same areas of far northeastern Oklahoma resulted in locally heavy rainfall across several counties with some flooding occurring in Craig County.
