    By 6 p.m., ComEd reported scattered outages, with more than 4,000 customers being affected. 

    Thunderstorms forecast for Friday afternoon and evening also prompted a Flash Flood Watch for much of the Chicago area.

    Conditions were expected to grow humid as scattered showers and storms develop. Some of those storms could become severe with heavy rain, winds up 60 mph, hail and frequent lightning possible. 

    A Flash Flood Watch was issued for much of the metropolitan area and across northern Illinois. The watch remains in effect from Friday evening through Saturday morning.

    Counties included in the watch are Boone, DeKalb, LaSalle, Lee, Ogle, Winnebago, Cook, DuPage, Grundy, Kane, Kendall, Lake, McHenry and Will. 

    Several areas north of Interstate 80 saw 1 to 2 inches of rain early Friday morning and the watch warns another 2 inches could fall during the evening storms.

    The heavy rain will likely taper overnight with some scattered showers possible early Saturday morning. Conditions cool off significantly for the weekend with temperature highs dropping to near 70 degrees and into the 60s for some areas.
