Winter Weather Causes More than 1,200 Flight Cancellations at Chicago O'Hare

— -- A blanket of snow and a blast of frigid air is causing travel troubles from the Midwest to the Northeast.

Chicago's O'Hare airport was hit hard on Sunday with over 1,200 flight cancellations, according to flightaware.com.

Today, airports across the country have racked up nearly 3,000 delays and 600 cancellations.

Up to a foot of snow fell in Minnesota, while Chicago saw about 8 inches and about 10 inches covered Detroit, according to ABC News Meteorologist Max Golembo.

New York City's Central Park got its first measurable snow accumulation of the season, with a dusting of just .4 inches.

Snow and wintry precipitation made for messy, difficult traveling conditions on Monday morning in the Northeast as commuters made their way into work. Boston saw 1 to 2 inches overnight and snow continued to fall into the early morning.

Below freezing temperatures are expected for millions across a large part of the country in the coming days as an arctic blast moves in from Canada.
