Fierce storms blew down power lines, tore off roofs, uprooted trees and even upended some small planes on the first day of summer. The suburbs, mostly to the north, bore the brunt of the violent weather. Funnel clouds were spotted in Naperville, Aurora, about 5 miles west of Grayslake in Lake County and four miles north-northwest of Sugar Grove in Kane County, but there were no confirmed reports of touchdowns. Winds were recorded at 60 to 75 mph.
