Parts of the Chicago area could see several inches of snow by Friday morning as a winter system moves into northern Illinois starting Thursday afternoon.
A winter weather advisory goes into effect Thursday across the region, warning of snow accumulation in some areas, ice and dangerous travel.
The advisory was issued for DeKalb, Kane, Kankakee, DuPage, LaSalle, Kendall, Grundy, Cook and Will counties in Illinois and Lake, Newton, Jasper and Porter counties in Indiana as of 12 p.m. Thursday at 6 a.m. Friday. In McHenry and Lake counties, the notice begins at 3 p.m.
The advisory warns of 2 to 5 inches of snowfall, with the highest totals near Lake Michigan in northeastern Illinois.
In Kankakee and parts of northwestern Indiana, snowfall rates could reach up to an inch per hour, with an ice icing adding to the mix.
Here’s a look at the latest NBC 5 Storm team totals:
The advisory warns of dangerous travel conditions in the area as snow and ice make roads slippery, especially for Thursday afternoon and evening journeys.
Despite some morning showers, the main event in terms of snowy weather should begin Thursday afternoon.
Snow accumulations are expected to build starting in the afternoon, with some places near the Illinois-Wisconsin border seeing up to six inches of snowfall, forecast models predict.
Lesser accumulations are possible in other parts of the area.
Another potential issue could occur along US 24 in Illinois and Indiana, with sleet possible in Jasper and Newton counties, as well as Livingston, Ford and Iroquois counties.
Between 1 and 4 inches of snow could fall in the area, but up to a tenth of an inch of ice is also possible as the storm spreads.
The snow will eventually end early Friday morning, with slippery conditions still possible as crews work to clear roads and sidewalks.
The possibility still exists of some lake effect snow on Friday, but accumulations are unlikely, based on current forecast models.
Good news is on the horizon after a chaotic week, with warmer temperatures and clear conditions expected on Saturday and Sunday. The two-day highs are forecast to reach the mid-30s in Chicago, and the weather will be a precursor to a continued warming trend that will push the highs back into the 40s next week.
