A winter weather advisory took effect for several Chicago-area counties overnight as snow, rain and freezing drizzle threaten the Monday morning commute.
With up to four inches of snow expected before the system moves out, Chicago-area drivers were urged to use caution ahead of what could possibly be a messy morning commute.
Periods of snow are expected to continue through the morning, though the heaviest snow was expected to fall overnight. An additional 1 to 3 inches were still expected before the snowfall comes to an end by the afternoon.
As temperatures hover around freezing, a wintry mix of snow, rain and freezing drizzle is possible, with the potential for a "minor glaze" of ice, mainly between 4 and 8 a.m.
