The forecast for the Philadelphia Eagles' pivotal clash against the Chicago Bears on Friday is calling for ice-cold conditions.

Chicago weather forecasts predict cloudy days with chances of rain, mid-40s to upper 50s temperatures, and a sunny weekend ahead.

Snow will continue overnight before tapering off early Sunday. Another 2-4” is possible, along with wind gusts up to 20 miles per hour. Light snow showers are expected again around sunrise Sunday.

Temperatures in the Chicago area are forecast to dip into the 30s starting Wednesday, and wind chills could fall to a low of 6 degrees Thursday morning, according to the National Weather Service.

Chicago's weather forecast includes mild temperatures with potential rain and fog, followed by colder conditions and possible snow showers as Thanksgiving approaches.

The Federal Aviation Administration issued two ground stops briefly at O’Hare on Wednesday between 8:45 a.m. and 10 a.m. because of snow and ice. Upon its expiration, a ground delay was issued until 9 p.m. Then, just before 10:45 Wednesday morning, a second ground stop was issued, lasting about an hour.

Thanksgiving week in the Chicago area will start out mild, the NBC 5 Storm Team said, with cloudy skies overhead, scattered rain and temperatures in the low 50s. But as the week inches closer to Turkey Day, the weather will be wintry -- with cold, wind and snow.
