Dense fog/hazardous driving conditions expected across the Chicago area

Visibility is expected to approach zero to an eighth of a mile early Thursday morning causing dangerous driving conditions across the Chicago area, possibly slowing the morning commute to a crawl. Individuals should be prepared for an extended and dangerous trip on the road late tonight and early this morning. With light winds, clearing skies and temperatures falling to or within a degree of the dew point, widespread dense fog formation is very likely.
