The winter weather advisory warns of potential travel disruptions due to slick road conditions caused by slushy snow accumulations. The morning commute on Friday could be impacted, particularly in areas like northwest Indiana, eastern Will County, Kankakee County, and parts of Cook County. Wind chills in the 20s may pose additional risks for those exposed to the cold. Drivers are advised to exercise caution as temperatures near freezing could lead to icy patches on roads.
