While winter storm warnings and weather advisories remain in effect, blowing snow, drifting snow and lake effect snow could affect the Thursday morning route.
Light lake-effect flurries could affect areas to the north, but the main threats will come from blowing snow and snow drift, especially in open areas.
High winds will likely affect the Thursday morning commute, officials said, and workers will continue to try to clear snow-affected roads.
A winter storm warning for Newton and Jasper counties in Indiana will remain in effect until 6 p.m. Thursday, according to the National Weather Service.
According to the alert, light snow is likely to continue through Thursday morning, and while only light accumulations are expected, blustery conditions will cause significant blowing and blowing snow problems, particularly on rural roads.
A winter weather advisory is also in effect for all of Cook County and will remain so through Thursday evening.
Forecasters say an additional 1 to 4 inches of snowfall is possible, primarily for Cook County and parts of Lake and DuPage counties.
This is in addition to snowfall on Wednesday, with many communities seeing 10 inches or more of snow in the affected area.
Depending on the strength of the lake-effect plume, even higher accumulations could be seen in some places, forecast models predict, and experts are urging residents to remain cautious while traveling on Thursday.
Residents who absolutely must travel are invited to respect the following advice:
- If you are involved in an accident or breakdown, stay inside your vehicle if possible. Activate the hazard warning lights and try to move to the side of the road if possible
- Make sure your gas tank is full before setting off for your destination.
- Keep a fully charged cell phone, warm clothes, blankets, food, water, and a first aid kit in your vehicle, along with extra windshield washer fluid and an ice scraper
- Inform friends and relatives of your travel schedule and the route you intend to take
The snow is expected to ease by Thursday evening, with below average temperatures likely to remain in the wake of winter storms.
