After 2 weeks of on-off snow, the polar vortex slaps the Midwest states of USA (Illinois, Wisconsin, Minnesota) with extremely cold winds with temperature in City of Chicago (Illinois) and suburbs dropping to record low -50F (-45C), colder than South Pole. Schools and all major places of business will be shut for next few days, while everyone is asked to stay indoors and stay warm.
