...Patchy Dense Fog Overnight...

Fog has developed over portions of the northern and northwest
suburbs of Chicago in Illinois, some of which is locally dense,
especially near the Wisconsin state line. If traveling, be
prepared for sudden changes in visibility. If you encounter fog,
slow down, maintain a safe following distance, and use your low
beam headlights. Where locally dense fog develops, patchy slick
spots may also occur where temperatures are at or below freezing.
