(CNN) A winter storm causing chaos on a busy travel weekend brought more high winds, snow and rain Monday as it pushed from the Midwest toward the Great Lakes and into the northeast US.

More than 1,300 flights within, into or out of the US were canceled Monday, according to FlightAware.com. Chicago's O'Hare International Airport was hit particularly hard, with more than 800 flight cancellations and delays averaging more than 40 minutes because of heavy snowfall.

The storm brought heavy snow from Colorado and Wyoming, where up to 60 inches of snow fell, through the Midwest, including Iowa, which got up to 17 inches. The storm hit the Chicago area hard, with more than 7 inches of snow, making it the strongest November storm since 1975 and the fifth-largest on record for the month.

At the peak of the storm, more than 220,000 customers were without power in the Midwest, particularly in the Chicago area. Winter weather warnings, watches and advisories continue to stretch from Indiana to New England, where snow will continue.
