Polar Vortex Brings Sub-Zero Temperatures To The US

On Monday, January 6th, more than 140 million Americans woke up to frigid temperatures - ones that had not been experienced in at least 25 years. The Midwestern part of the country bore the brunt of the cold. Fort Wayne recorded a bone chilling high of -13°F, while Chicago reported an even lower -16°F. And those numbers were without the wind chill, (the effect the wind has on lowering the temperature), factored in.
