A Flash Flood Warning was issued for several Chicago-area counties following a Tornado Warning that expired for Cook and Will counties Friday evening.
The Flash Flood Warning included southeastern Cook County, north central DeKalb County, southeastern McHenry County, Northeastern Kane County, DuPage County, northern Will County, east central Kendall County and northern Lake county and remained in effect until 12:45 a.m.
This comes after a Tornado Warning for south central Cook County and central Will County expired at 5:15 p.m.
A severe thunderstorm capable of producing a tornado was located near Monee, Illinois just before 4:45 p.m. and was moving east at 20 mph, the warning stated.
By 5:15 p.m. the storm had weakened below severe limits, officials said, and appeared no longer capable of producing a tornado. Heavy rain was still possible with the storm, however.
Monee officials said little damage was reported shortly after the storm. One home sistained serious damage after a tree fell onto the house and damaged the roof, fire officials said.
Oswego East High School rescheduled its varsity football game from Friday evening to 9 a.m. Saturday due to the weather, school officials announced.
O'Hare and Midway airports reported some delays due to the inclement weather. Delays averaged 30 to 45 minutes long.
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.
