...Patchy Fog this Morning...

Patchy fog has developed early this morning across portions of
interior northern Illinois outside of Chicago, some of which has
become locally dense with visibilities of one quarter mile or
less. Be prepared for sudden changes in visibility over short
distances during the morning commute. Slow down, increase
following distance, and use low beams when driving in fog.
