Several clusters of thunderstorms developed along a nearly stationary frontal boundary draped across central Illinois during the late afternoon and evening of May 29th.  Four landspout type tornadoes touched down beneath developing cells across portions of Christian and Macon counties.  Other storms produced isolated wind damage and hail as large as quarters.  In addition, numerous cells training over the same locations dropped as much as 2 to 3 inches of rainfall in a short period of time along the I-70 corridor.  As a result, localized flash flooding occurred across portions of Effingham and Clark counties, with the most significant flooding taking place in West Union in Clark County where several feet of water was flowing across town.
