Chicago, if you're not bundled up already, godspeed.
The Midwest is experiencing sub-zero temperatures unlike the region has ever known, with the deadly polar vortex wiping across the Great Lakes and pushing towards New England.
On Tuesday, the aptly named "Windy City" of Chicago was zapped with an arctic freeze with temperatures dropping to negative 25 degrees.
Temperatures in Chicago could drop to an astounding -25 degrees by Tuesday night, the National Weather Service said. https://t.co/kxBloM9ujr— HuffPost (@HuffPost) 1548691556.0
As forecasters warned, the temperature in Chicago dropped further to a wind chill of negative 52 degrees on Wednesday morning, shuttering schools and suspending mail service.
Residents are being encouraged not to open their mouths if they must step outside.

The polar vortex is a large area of "low pressure and cold air surrounding both of the Earth's poles," according to the National Weather Service, and a disruption is expanding it into the northern hemisphere. Experts are calling this arctic migration life-threatening, particularly for areas that do not experience drastically cold weather.
Brian Hurley, a meteorologist with the Weather Prediction Center, described blast's deadly consequences.
"You're talking about frostbite and hypothermia issues very quickly, like in a matter of minutes, maybe seconds."
