A large complex of severe thunderstorms developed along a stationary frontal boundary across eastern Iowa during the afternoon of June 30th, then tracked eastward along the boundary across north-central Illinois during the evening.  These storms produced damaging wind gusts of around 60 mph and locally heavy rainfall along and north of a Canton to Minonk line. Additional strong thunderstorms developed further south in Missouri and pushed into the area during the evening, producing widely scattered wind damage along and west of I-55. Very high rainfall rates led to flash flooding across parts of Marshall and Stark County. The flooding continued into the morning hours of July 1st.
