TODAY SUNRISE: 5:16 AM SUNSET: 8:31 PM

Chicagoland weather radar shows severe thunderstorms in northern Illinois with the heaviest storms between Quad Cities and Rockford at 10:46 a.m.

Satellite images show a large area of convective clouds in northern Illinois, central Illinois, northern Missouri, most of Iowa, eastern Minnesota, and all of Wisconsin at 9:37 a.m. CDT.

The most intense thunderstorm activity is expected in the northwest suburbs and O’Hare International Airport area at about 1:00 p.m. CDT. The National Weather Service expects “explosive severe thunderstorm development” across northern Illinois along and north of I-88, but is not certain if the intense complex of severe thunderstorms will maintain strength into the Chicago area.
