The episode as NWS PAH wrote it up.
A cluster of thunderstorms slowly intensified over central Missouri during the late afternoon hours. The intensifying thunderstorms then moved southeast, producing isolated wind damage during the evening as they encountered a more unstable environment. The storms developed ahead of a small disturbance in the upper levels of the atmosphere that tracked southeast from the Kansas City metro area.
