...Areas of Fog Expected Through Morning... Fog has developed across the area thanks to lingering moisture, mostly clear skies, calm winds, and haze from fireworks. Current visibilities range from 2-5 miles in most areas, except near Lake Michigan where visibilities are below 1 mile. Expect conditions to deteriorate more through sunrise, with denser patches of less than one quarter of a mile possible. Visibility will vary widely over short distances. If driving, be alert for changing conditions. Leave plenty of distance ahead of you, and use low beam headlights. Conditions should begin to improve shortly after sunrise.

...Patchy Dense Fog Early This Morning... Patchy dense fog near the Kankakee River Valley could cause visibility of one quarter mile or less in spots. This includes portions of the Interstate 65 and 57 corridors. If driving, be alert for sharp visibility reductions and rapidly changing conditions. Leave extra distance between your vehicle and other vehicles and use low beam headlights. The fog should quickly improve by 700 AM.
