Chicago was in the bullseye of a heavy winter storm that threatened to dump a foot of snow in some areas around the Great Lakes by Friday night, wreaking havoc on travelers, closing schools and forcing the cancellation of hundreds of flights nationwide.
More than 1,000 flights have been canceled at the city's O'Hare and Midway global airports.
Winter storm warnings were issued by the National Weather Service for parts of northwest OH, southern Lower Michigan, northern IN, northern IL, southern Wisconsin and eastern Iowa, where show is expected to be the heaviest.
"We are getting more snow today, tomorrow and Sunday than we have normally gotten in the last few winters at any one period of time", said Chicago Mayor Rahm Emanuel, encouraging residents to stay indoors. He says "we're tried and tested here". Numerous school districts in Nebraska and Iowa also canceled or delayed schools Friday because of the snow and frigid temperatures, according to the Associated Press.
