The Chicago area is seeing its biggest snowfall of the season on Tuesday as a winter storm that began Monday continues to hit the region, leaving several inches of snow on the ground in parts of the region.

Here are the latest updates on the winter weather across the Chicago area:

Lake-Effect Snow Still Possible as Weather System Continues to Churn Through Region

Tuesday morning into the afternoon, the Chicago area will continue to see snow with additional lake-enhanced snow showers. Forecast models show the snowfall diminishing by Tuesday afternoon, leaving behind an additional 1 to 3 inches of accumulation.

Once the center of the storm passes to the east, the snow will wind down, but for areas along Lake Michigan it could be replaced by lake effect snow showers later Tuesday afternoon and evening, continuing into Wednesday morning for some.

These showers have the ability to produce quick accumulations in any given location where they set up. They could also move east into northwest Indiana before ending later in Wednesday afternoon.

Chicago's Streets and Sanitation Department Transitions to Clearing Side Streets

Chicago’s Department of Streets and Sanitation has transitioned its snow vehicles to clear snow from residential streets after clearing main roads and arterial streets, the department says.

The city of Chicago has received nearly six inches of snow since the storm began Monday, and could see more as lake-effect snow is possible through the early evening hours.

DSS staff will continue to monitor conditions through the city, and will spread salt and plow streets as needed, the department said.

The Chicago Department of Streets and Sanitation said early Tuesday that it had deployed more than 200 snow vehicles to begin clearing snow from residential streets.

Salt spreaders have also been deployed, the city said, with agency staff monitoring weather and ground conditions to adjust resources as needed.

The Illinois Department of Transportation also mobilized its fleet of snow vehicles to combat the storm, with salt spreaders and plows to keep roads safe.

“Our crews at IDOT are mobilized and prepared for the return of winter weather this week,” Acting Illinois Transportation Secretary Omer Osman in a statement. “As always in periods of inclement weather, the safest option is to stay home. If you must drive, slow down, give the road your undivided attention and please do not crowd our plows.”

The department says it will have more than 1,800 pieces of equipment and trucks available statewide, and crews will work throughout the storm to salt roads and to plow snow.

The Illinois Tollway is also deploying its fleet of nearly 200 snowplows to cover the highways under its jurisdiction, and will activate the Snow Operations Center to coordinate responses to the storm.

Drivers whose vehicles become disabled during the storm are being asked to remain in their cars, activate their hazard lights, and to call *999 from a phone to ask for assistance from the Illinois Tollway and Illinois State Police. Drivers will be asked to provide the roadway, direction of travel and the nearest milepost or cross road to help authorities locate their vehicles.

ComEd Opens Emergency Operations Center

ComEd opened its Emergency Operations Center Monday in anticipation of the winter storm, saying it was also "getting equipment and additional crews in place to respond to potential power interruptions."

The utility giant's priority in responding to outages caused by storms is focused on restoring facilities like police and fire stations, nursing homes and hospitals first, ComEd said, followed by areas with the greatest number of customers.

ComEd encouraged customers to take the following precautions:

  • If a downed power line is spotted, immediately call ComEd at 1-800-EDISON1 (1-800-334-7661). Spanish-speaking customers should call 1-800-95-LUCES (1-800-955-8237).
  • Never approach a downed power line. Always assume a power line is extremely dangerous and energized.
  • In the event of an outage, do not approach ComEd crews working to restore power to ask about restoration times. Crews may be working on live electrical equipment, and the perimeter of the work zone may be hazardous. Additionally, for the safety of themselves and the public, crews are practicing social distancing.

ComEd urged customers to contact the company immediately if they experience a power outage, saying they can text OUT to 26633 (COMED) to report an outage and receive restoration information, call 1-800 EDISON1 (1-800-334-7661), or report outages via the website at
