PHOTOS: Chicago area hit by winter storm

CHICAGO — The Chicago area is on Day 4 of snowfall. Chicagoans woke up Sunday morning to another 3 inches of snow blanketing the area.

A winter storm moving across the Great Lakes dropped about a foot of snow in some Chicago areas and created treacherous driving conditions Friday, closed schools and forced the cancellation of hundreds of flights.

The National Weather Service issued winter-weather warnings and advisories across the upper Midwest. The snow that began falling late Thursday afternoon was expected to continue through Friday as the storm moved east.

More snow is expected to fall throughout Sunday morning.
