Fog causing delays at airports; Advisory issued

wednesday-2

CHICAGO — A Dense Fog Advisory (grey-shaded area on headlined map to the right) for visibility dropping below a quarter-mile over much of the Chicago area across northeastern Illinois into northwest Indiana will be in effect until 9PM CST this Wednesday evening.

As a cold front drops south out of Wisconsin, visibility will improve behind the front, but at the same rain will accompany and follow as temperatures fall behind the front, so that freezing rain will possibly spread south into northern Illinois as the visibility slowly improves. Note the Freezing Rain Advisory remains in effect for counties north and west of Chicago (purple-shaded area on headlined map above) late afternoon into the evening hours.
