Airlines struggled to get passengers stranded at Chicago's two airports re-booked and on their way Saturday, a day after a snowstorm forced the cancellation of more than 800 flights.

More than 700 flights at O'Hare International Airport and approximately 100 flights at Midway Airport were canceled Friday as the powerful storm system dumped up to 6 inches of snow, the Chicago Tribune reported.

The heavy snowfall forced city officials to reroute 15 bus routes off Lake Shore Drive, and more than160 motorists had to be assisted by the Illinois Tollway Authority.

The buses were finally able to resume their route Saturday, but slick roads remained a concern.

"We've had a bunch of accidents and spinouts all over the district," Illinois State Police trooper Michael Bobko told the Tribune.

The city brought out all 278 plows to tackle the drifting snow, the Chicago Sun-Times reported.

Temperatures are expected to rise to nearly 40 degrees on Sunday, when rain is likely, according to myFOXchicago.com.
