CHICAGO (WLS) – As students wrap up their two-week vacation, snow could welcome them back to the classroom.

An AccuWeather warning is in effect as lake-effect snow began Sunday evening as a winter storm moved south of the Chicago area, ABC7 meteorologist Cheryl Scott said.

ABC7 meteorologist Jaisol Martinez said Sunday will be cold with highs in the 20s.

Most of Cook and Lake Counties in Illinois will see one to two inches of snow overnight into Monday.

If lake-effect snow bands remain in one location for several hours, 2 to 5 inches of snow could fall in some locations, Martinez said.

While it’s not much, Martinez and Scott warned it could impact Monday’s morning commute due to slick road conditions.

The winter weather comes as Chicago Public School students prepare to return to class on Monday.

The weather continued to cause problems for some residents in South Shore on Sunday evening. Crews worked for hours to deal with a power outage while a warming bus sat outside the home after some residents were forced to go outside in the winter.

“It’s inconvenient because we want to go in,” said resident Trachon Carson. “It’s cold out here.”

The lights of the emergency services reflected in the dark windows of the two affected high-rise condominium buildings in South Shore.

“Our lights are out, so we can’t even get in,” Carson said. “We got groceries. We can’t get up to where we live.”

A power outage in the area left at least 183 customers in darkness and cold temperatures, according to ComEd.

“I was working for my nonprofit,” said resident Shanette Coleman. “We had a Zoom meeting and the lights just completely went out. No heating. Nothing. No electricity. There is no way to provide any services.”

This also includes working elevators.

“We have people living in these buildings who have accessibility needs but can’t meet them,” Coleman said. “And I’m afraid to go up the stairs alone and it’s completely dark in the hallway.”

According to authorities, the outage occurred just after 4 p.m. Sunday at the two buildings near 73rd and South Shore Drive.

A city bus was parked out front for people to warm up, just as snow loomed in the shape of a lake in the coming hours.

“It’s extremely cold here, and then if you live on the lakeshore and live on the lakefront, the temperatures in this area are actually at least 12 degrees cooler,” Coleman said.

At last check, ComEd said power was expected to be restored by 11:15 p.m. Sunday and the cause of the outage was still under investigation.

“These conditions are unacceptable,” Carson said. “Like I said, it’s not cool to pay that much money.” 19:16
