Storms passing the Rockford area at about 5:00 a.m. were forecast to enter the northwest suburbs of Chicago by about 6:00 a.m. The storms have a history of dime- to penny-size hail. Flash flooding is a possibility, but no official flash flooding advisories, watches or warnings have been activated by the NWS as of 5:50 a.m. Heavy rain is likely through the morning rush hour and will possibly continue to about 10:00 a.m. to 2:00 p.m. Scattered severe thunderstorms are possible late this afternoon and evening, and possibly until about noon Tuesday. Record heat sits south of us in several states.
