Parts of the US Are Colder Than Antarctica Amid 'Polar Vortex'

Temperatures as low as minus 30 degrees Fahrenheit were recorded in Wisconsin on Wednesday morning as part of the “polar vortex” deep freeze affecting much of the Midwest.

Only one temperature station in Antarctica recorded a temperature lower than minus 30 degrees Fahrenheit, according to AccuWeather.

The deep cold has already cancelled some 27-hundred flights across the nation-- with the worst weather conditions yet to come.

Those who have no choice but to venture outside, make sure to wear plenty of layers.

But officials say you should stay indoors if possible -- frostbite can set in in less than five minutes.
