Wider weather episode

A strong upper level disturbance and associated cold front translated into the Southern Plains on the 8th. An unseasonably warm and moist air mass had spread into eastern Oklahoma ahead of this system, which resulted in weak instability across the area. A line of thunderstorms developed into eastern Oklahoma from the west during the morning hours of the 8th. Strong wind fields and wind shear associated with the approaching upper level system, combined with the weak instability, supported an environment in which the stronger thunderstorms within the squall line were able to develop low level circulations. One such circulation resulted in a brief, weak tornado and wind gusts to 88 mph in Osage County.
