A severe thunderstorm capable of producing a tornado was located near Timerlane, or near Belvidere, moving northeast at 30 mph around 5:50 p.m., according to the National Weather Service. Another severe thunderstorm capable of producing a tornado was also located over Candlewick Lake, or over Poplar Grove, moving northeast at 30 mph at 5:57 p.m.

A tornado-producing storm was also located over Oak Brook, moving northeast at 25 mph around 4:50 p.m., according to the National Weather Service.


As of 5:36 p.m. Saturday, 156 flights have been canceled at O’Hare with an average of 1 hour delay; and no flights have been canceled from Midway airport, according to FlightAware.

According to the Storm Prediction Center, the entire Chicago area is under a “slight” risk for severe weather on Saturday – a level 2 out of 5. There is a 5% probability of a tornado within 25 miles of any given point in the Chicago area on Saturday, ABC7 Meteorologist Cheryl Scott said Friday.

Several rounds of showers and storms are expected to develop Saturday with the potential to turn severe. Threat of storms on Saturday afternoon and evening are contingent on morning destabilization of atmosphere, which scattered storms on Saturday morning may act to inhibit. All storm threats possible, but high winds are most likely, Dutra said.

Scattered showers and storms are possible earlier Saturday. Rumbles of thunder won’t be surprising, but the better chance for severe weather will be in the later afternoon and evening.

Thunderstorms are expected to develop across northwest Illinois to the I-39 corridor after 1:00 p.m. and move eastward into northeast Illinois and northwest Indiana through the afternoon and early evening. They likely will not make it to the Chicago area until closer to 5:00 p.m. It will then hit northwest Indiana in the 6:00 p.m. to 7:00 p.m. timeframe.

The system heading toward the Chicago area already hit Kansas on Friday and the images coming out of there are terrifying.
