An area of low pressure tracking along a nearly stationary frontal boundary triggered a round of severe thunderstorms across central Illinois during the afternoon of June 10th.  A line of storms produced 60-80mph wind gusts and widespread wind damage from portions of Tazewell and McLean counties southeastward through Champaign and Edgar counties.  Two brief EF-0 tornadoes spun up along the leading edge of the line, producing pockets of enhanced damage on the southwest side of the city of Champaign.  Additional thunderstorm cells that developed further west later in the afternoon produced golf ball to tennis ball sized hail near Beardstown in Cass County. Flash flooding was also reported in northern Vermilion County.
