In what one meteorologist is calling a "polar vortex," cold air from the North Pole is being sucked down into the U.S. this week, driving temperatrures so low that countless temperature records will likely be broken.
The freeze has already started, but will begin in earnest on Sunday and extend into the early week. A perfect combination of the jet stream, the polar vortex, and already-low winter temperatures will make the freeze so historic that Tallahassee meteorologist Ryan Maue says those under the age of 40 won't have seen similar weather.
Fargo, North Dakota will hit 25 degrees Fahrenheit below zero, while International Falls, Minnesota will see -31 degrees. Chicago and Indianapolis will hit 15 below. Those temperatures are lethal to unprotected people and the wind chill could take the effective temperature down to nearly 70 below zero.
Here are some photos of how damn cold it is:
