A line of thunderstorms moved southeast from southern Wisconsin into northern Illinois during the late afternoon of Sunday July 22nd.  The line of thunderstorms interacted with a lake breeze moving west through Cook county from Lake Michigan.  Most of the damage from these storms was in the form of trees and limbs down and power lines down which were received from: Belvidere and Capron in Boone county; Richmond, Crystal Lake and McHenry in McHenry county; Barrington and Elk Grove Village in Cook county; Wauconda and Grayslake in Lake county; Lombard in Dupage county; Yorkville in Kendall county;  Aurora in Kane county; Bradley in Kankakee county and Streator in La Salle county.  Trees were reported down on a car in Elmhurst in Dupage county at 1545 CST.  A waterspout developed on the leading edge of this line of thunderstorms as it moved southeast across Lake county in Illinois one mile east of Winthrop Harbor.  No injuries or damage were reported from this waterspout.  50,000 people lost power across the Chicago area during the storms.  A 49 year old woman was struck by lightning around 1500 CST while walking through Miller Meadow in Maywood.  The woman died from extensive burns the next day.
