An approaching cold front interacted with an unstable and sheared environment to trigger a broken line of supercell thunderstorms across the Illinois River Valley during the late afternoon of April 8th.  The storms tracked southeastward across central Illinois, eventually congealing into a solid line before dropping to near the I-64 corridor by late evening.  Wind gusts of 60-70 mph were observed, with some of the stronger cells producing gusts in excess of 70 mph.  As a result of the strong winds, widespread wind damage was reported.  In addition, a few of the storms dropped hail as large as ping pong balls.
