Snowfall should begin in the Chicago metro area early Thursday, coinciding with the morning commute, which could cause serious delays and lead to crashes. At least 2 to 4 inches are expected in the immediate metro area, while the Joliet and Kankakee areas could see as much as 7 inches, forecasters said. What’s more, most of northern Illinois also could be coated with anywhere from a “glaze of ice” to a tenth of an inch of ice.
