-13 Degree Weather Has Brought Chicago's O'Hare Airport To A Near Standstill

Record-breaking cold has hit the Midwest, and more than 1,500 flights into and out of Chicago’s O’Hare International Airport today have been cancelled.

The National Weather Service is warning of “bitterly cold” conditions, with highs from -9 to -13 degrees, and wind gusts up to 40 mph.

Even though planes are no strangers to strong wind and freezing temperatures when they fly at 30,000 feet up, ice and snow on the runways make takeoffs and landings more dangerous.

According to FlightAware.com, over 60% of those scheduled have been cancelled. More than 300 flights scheduled for Tuesday have already been cancelled as well.

Here’s how the airport looked Monday morning:
