In the Chicago area, only a few inches of snow fell, but wind gusts of up to nearly 50 mph blew the roof off a building at the Navy Pier and canceled at least 1,375 flights at O’Hare International Airport and more than 300 at Midway International Airport. The cancelations left some travelers stranded overnight at O’Hare, where officials set up about 200 cots.

On Monday, about 75 flights were canceled, Chicago Department of Aviation spokeswoman Karen Pride said.
