A fast-moving winter system could dump several inches of snow on parts of the Chicago area Friday.
A Winter Weather Advisory has been issued for most of northeast Illinois and parts of northwest Indiana, warning of 3 to 5 inches of snow expected, with isolated locations potentially seeing up to 6 inches.
The highest totals are expected south of Interstate 80, though much of the Chicago area is expected to see between 2 and 4 inches. Areas far north of the city may only see between 1 and 2 inches.
DeKalb, Kane, DuPage, Cook, LaSalle, Kendall, Grundy, Will, and Kankakee Counties are all under the advisory beginning at noon Friday and ending at midnight Saturday morning, according to the National Weather Service.
Lake, Porter, Newton, and Jasper Counties in Indiana are also listed.
Timeline: What to Expect and When for Friday's Snowfall
The snow is expected to begin falling during the late morning and early afternoon hours, spreading west to east before ending mid- to late-Friday evening.
The NWS warns that snowy conditions could make for difficult travel during the afternoon and evening rush hours.
"Given the cold air temperatures, expect roads to become snow covered," the NWS reports.
Temperatures stay cold Friday, with highs in the teens and wind chills near 0.
Another chance for snow returns Saturday in northwest Indiana as temps fall into the single digits with sub-zero wind chills.
A Wind Chill Advisory is in effect for Winnebago, Boone, Ogle, DeKalb and Kane counties beginning at 5 a.m. Saturday and continuing until 1 p.m. The advisory warns of wind from 15 to 25 below zero.
The holiday weekend will see the bitter blast continue. Highs stay in the teens with more sub-zero wind chills forecast.
