...Patchy Dense Fog through Mid Morning...

Patchy shallow dense fog outside of Chicago between the I-88 and
I-80 corridors down to roughly the Kankakee River will cause
localized poor visibility down to as low as one quarter mile,
along with rapid changes in visibility. Motorists are advised to
use extra caution. Reduce speed, increase following distance, and
use low beams when driving in dense fog.
