Thunderstorms that raked the Chicago area on Sunday knocked out power for thousands of people in the west, southwest and south suburbs and led to the cancellation of more than 100 flights at O’Hare and Midway airports.

After the storms swept through the area, nearly 9,000 ComEd customers in the west, southwest and south suburbs were without power, according to ComEd. Most of the outages were reported near Harvey and Blue Island, where more than 6,300 customers were without power Sunday night. Crews were still working to restore service as of late Sunday. And about 40 customers on the South Side had no power Sunday night.

The storms forced cancellation of more than 130 flights at O’Hare, and some flights were delayed for more than an hour. Midway had few cancellations and some delays of up to 30 minutes, according to the Chicago Department of Aviation.

On Sunday evening, trains along the Union Pacific North Line between Ogilvie Transportation Center and Kenosha, Wis., were delayed because of the weather in the area, according to Metra’s website.

Although Sunday started out warm and sunny in the Chicago area, the thunderstorms — bringing heavy rain, up to 70 mph winds and quarter-size hail — hit late Sunday afternoon, said Ricky Castro, a weather service meteorologist. A severe thunderstorm watch was called off about 8:30 p.m.

There was a minor chance of tornadoes forming on Sunday, but there were no funnel cloud sightings in the Chicago area, according to the weather service

Monday will bring unseasonably warm temperatures that could reach the upper 80s, with a 30 percent chance of rain in the morning.

Meteorologists expect the balmy weather to shift to thunderstorms after midnight Monday, with a 70 percent chance of precipitation.

The storms will likely stretch into Tuesday morning, with highs hovering in the upper 60s, forecasters said.
