The Midwest is getting hit by a powerful polar vortex and people are feeling a blistering wind chill around Chicago. Schools are closed, hundreds of flights have been delayed or canceled and parts of the region could be colder than the Arctic Circle.
The polar vortex is bringing some of the coldest weather in a generation. The upper Midwest will face temperatures 40 degrees below normal with wind chills in the negative double digits.
So far, the weather is blamed for at least six deaths in Illinois, Iowa, Indiana, Wisconsin and Minnesota.
