Strong thunderstorms, hail moving toward some NW and N suburbs
10:02AM: One inch, or quarter sized hail was reported at the Rockford Airport at 9:58. There is a report of some broken glass from hail just south of Rockford. If you live in McHenry, Lake or far northern Cook County, it’s time to put the car in the garage (if that’s an option).
9:40AM: Thunderstorms developing along a warm front are expected to impact some of Chicago’s northern suburbs late this morning. A few of the stronger cells will be capable of producing 1″ hail and wind gusts of 50 to 60mph.
The best chance of rain between 10AM and 1PM will be over McHenry, Lake (IL), northern DeKalb, northern Kane, and far northwest Cook County . Areas from the city southward should stay dry.
