Some roads are flooded and thousands are without power Sunday morning after overnight storms in the Chicago area.
A system bringing torrential rainfall and damaging winds moved through the area Saturday night into early Sunday morning, according to the National Weather Service.
A flood advisory was issued until noon Sunday for regions that saw the heaviest downpours. Those include Joliet, Elgin, Bolingbrook, Oak Forest, West Chicago, Chicago Heights and Orland Park, meteorologists said. Some of those areas saw between 3 and 4 inches of rain overnight.
There are also reports of flooding in Chicago, including a viaduct near 47th Street and Archer Avenue in Archer Heights and another at 95th and South Cottage Grove in Roseland.
As of 8 a.m. Sunday nearly 65,000 were without power, with 29,000 of those in Cook County, according to ComEd.
Saturday night’s storm prompted severe thunderstorm warnings and delayed the Savannah Bananas exhibition game at Rate Field by an hour and 45 minutes past the 7 p.m. start time.
Our stormy pattern will continue through mid-week warm and humid conditions as well. Cooler and less humid conditions return Wednesday through weeks end. #ILwx #INwx pic.twitter.com/hZgEr4cXuD

Sunday’s weather is expected to be drier — good news for the Chicago Air and Water Show crowds — before another round of storms moves through Monday evening.
Temperatures are expected to climb near 80 degrees by Sunday afternoon with rain clouds replaced by partly sunny skies. At night, temps should fall to around 70 degrees with wind gusts as high as 15 mph.
Monday will be warmer with temps near 90 degrees, but more showers are expected. There’s a 30% chance of showers and storms during the day and a 60% chance at night. That system may linger overnight into Tuesday morning.
The rest of the week should be clear of rainfall. Highs are expected to hover in the high 70s on Wednesday and Thursday. Friday should be sunny with a high near 84 degrees.
