Arctic cold front bites northern, central regions of United States

Wind chills are wreaking havoc in the northern and central parts of the United States while it has snowed heavily from the Eastern Plain to the Great Lakes of the country due to invasion of arctic cold air.

The National Weather Service said in an advisory posted at its website Sunday that the northern and central parts of the U.S. will expect the coldest temperatures in about two decades because of the polar cold front this week, with some 140 million people to be impacted. Combined with gusty winds, the temperatures will result in "life-threatening wind chill values as low as 60 degrees (Fahrenheit or 51 degrees Celsius) below zero" in some areas.
