CHICAGO (STMW) — With temperatures expected to rise above freezing for the first time of 2014 Friday, forecasters urged drivers to use caution as fog rolls into the area for the morning commute.

A freezing fog advisory is in effect until noon for Chicago area counties, including Cook, Lake, DuPage and Will, according to the National Weather Service.

Commuters were met with fog, light mist and rain, which could create icy patches on roadways Friday morning before steady rain moves in after 1 p.m., forecasters said.

Visibility was down to two miles, with some areas at less than a quarter of a mile, the weather service said.

Due to low visibility, more than 100 flights were canceled at O’Hare International Airport as of 7:40 a.m., according to the city’s Department of Aviation. Also, flights at both O’Hare and Midway International Airports were experiencing delays, while Midway canceled a “minimum” number of flights.

The fog could become more dense after 10 a.m. as temperatures inch toward Friday’s forecasted high of 39 degrees, according to the weather service.

Forecasters said there would be a potential for flooding in some areas this weekend as rain continues through tonight, with warmer temperatures melting much of the snow that piled up earlier this week.

Saturday’s high temperature is forecasted at 38 degrees with a chance of rain and snow, while Sunday could top out at 43 degrees with clear skies, the weather service said.
