Chicago Weather: A Very Foggy Tuesday Morning Over The City

No, it was not just your imagination (or your dirty windshield): Dense fog blanketed Chicago highways and skyscrapers Tuesday morning.

According to the National Weather Service, visibility was below a quarter of a mile.

Heads up! Areas of dense fog will continue developing this morning leading to localized visibility below a quarter of a mile. With temperatures near the freezing mark, a few slick spots may develop on bridges and overpasses, too. #ilwx #inwx pic.twitter.com/FZjWtGpEN9

Areas of dense fog continue this morning, especially along the Lake Michigan shoreline. Take it SLOW if you encounter fog and increase following distance between the car in front of you. #ilwx #inwx pic.twitter.com/aPcBF26ivR

And the fog isn't going anywhere soon.

A dense fog advisory for Cook County is in effect until 3 p.m. this afternoon. While driving, use headlights and plenty of distance ahead of you.

Dense fog persists along the IL shores thru at least early this PM. Visibilities of a 1/4 mile or less expected within a few miles of the lake. Motorists should thus be prepared to encounter rapidly changing visibilities as they approach the lake. #ilwx pic.twitter.com/VV4L3LDW3I
