Over the weekend, 1,300 flights were canceled at O'Hare International Airport in Chicago and more than 300 flights were canceled at Chicago's Midway Airport all because of severe winter weather.
Meanwhile, the Southland had warm, beach-friendly weather with record-breaking temperatures for this time of year. At Los Angeles International Airport, temps hit 83 degrees, beating a 1952 record of 82 degrees.
Other parts of the nation were not so lucky. Major highways were closed across the Midwest as snow and ice made for a dangerous drive for commuters.
The storm system in the Midwest dropped nearly 2 feet of snow in parts of Minnesota and Wisconsin.
The snow was so heavy that it collapsed the roof of the Minnesota Metrodome, home of the Vikings. The inflatable roof sagged and tore in two places, dumping snow on part of the field. No one was hurt, but the Vikings game against the New York Giants had to be moved to Detroit's Ford Field.
Stadium officials were trying to repair the roof in time for the Vikings' next home game, Dec. 20 against Chicago.
The worst of the storm for the Midwest has passed but residents are still dealing with frigid temperatures expected to fall well below zero.
At least six weather-related deaths have been reported, and as the storm heads east, heavy snow was reported in parts of Indiana and Michigan on Monday.
According to the National Weather Service, the storm is also heading northeast toward Pennsylvania, New York and Canada.
