How to check Illinois road conditions
The Illinois Department of Transportation issued a warning to drivers, advising of slick conditions along with reduced visibility and urged residents to avoid traveling if possible.
“If you must travel, be advised your destination could have significantly higher amounts of snow than where your trip originated,” the alert said. “Slow down, anticipate much longer travel times, increase braking distances and expect conditions to deteriorate.”

Officials issue ‘over-salting’ warning
Chicago officials urged residents residents to not use excessive amounts of salt on their sidewalks and driveways.
The Metropolitan Water Reclamation District of Greater Chicago posted the reminder on Sunday afternoon, saying that it takes a surprisingly low amount of salt to properly melt away snow and ice.
According to officials, a 12-ounce cup holds enough salt for 10 sidewalk squares, or a 20-foot driveway.
Predicted snow totals
Roman noted an estimated 1-4 inches of snow fell in counties under the winter weather advisory overnight, with more than 4 inches recorded in Joliet, and 3.6 inches recorded in Chicago. Morning rain wiped out the totals in some of areas, Roman said, adding that precipitation in those parts may stay in the form of rain as the day continues.
By Tuesday evening, counties in the advisory may only see an additional inch of snow accumulating.
North and west counties under the winter storm warning however could see snow totals of between 6 and 8, or even 9 inches by Tuesday night, forecast models show. Between 2 and 5 inches of snow was likely to fall between 7 and 10 a.m., with morning commutes likely impacted, Roman said.
“Plan for a messy morning commute, with slick roads and reduced visibility,” Roman said, adding that morning winds of 20-25 miles per hour were expected to increase as the day continued.
ComEd officials Monday announced with the company’s Emergency Operations Center will open Tuesday to assist with any problems that may arise.
“The kind of snow forecasted this week can be especially problematic because it can cause branches and entire trees to topple onto our power lines,” COO Dave Perez said in a statement.
According to Roman, widespread snow was expected to continue falling throughout the day, with most areas seeing heavy snow through 9 p.m., and tapering overnight.
