Records are being shattered and communities are enduring the harshest cold in years as the polar vortex tightens its grip on the midwestern United States.
After the polar vortex plunged southward, temperatures plummeted under 20 below zero F from North Dakota to northern Illinois on Wednesday morning.
Biting winds made the extreme cold more life-threatening as AccuWeather RealFeel® Temperatures dropped under 50 below zero. Frostbite can occur in mere minutes on exposed skin in these conditions.
Among the deaths from the snow and cold that struck the Midwest was a man found frozen to death in a garage in Milwaukee, Wisconsin, according to the Associated Press.
