A nearly stationary frontal boundary extending from southern Lake Michigan southwestward to the Iowa/Missouri border triggered a round of severe thunderstorms across portions of west-central Illinois during the late afternoon and evening of July 10th.  Most of the storms were confined to areas along and west of the I-55 corridor.  Due to increasing amounts of low-level wind shear ahead of an approaching disturbance, several of the storms began rotating...with one cell spawning a brief tornado just south of Princeville in Peoria County.  Other storms produced 60 to 70mph wind gusts and hail as large as tennis balls in Fairview in Fulton County.
