An approaching cold front triggered scattered severe thunderstorms across portions of central and southeast Illinois from the evening of June 17th into the early morning of June 18th.  The hardest hit locations were north of the I-74 corridor from Toulon in Stark County southeastward to Rantoul in Champaign County, where wind gusts of around 60mph downed numerous trees and power lines.  A couple downbursts with estimated 70-80mph winds created enhanced areas of damage in Peoria Heights, just northwest of Roanoke in Woodford County, and near El Paso in southeast Woodford County.  Torrential rainfall of 3 to 4 inches resulted in flash flooding of many county roads from northeast Peoria County and Stark County eastward to northern McLean County.  Water rescues were necessary in the city of Normal due to the excessive rainfall rates.  Other areas that experienced severe weather were from near Beardstown in Cass County eastward to Springfield...and across Effingham and Clay counties.
