Patchy dense fog across the Chicago area this Monday morning

CHICAGO — Temperatures and dew-points are closing together early this Monday morning resulting in patchy dense fog developing mainly west and north of Chicago where a Dense Fog Advisory (grey-shaded area on the headlined map) is in effect until mid-morning (9 to 10AM CDT).
