REPUBLIKA.CO.ID, MILWAUKEE/COLUMBUS - As the Midwestern United States shivered through the region's lowest temperatures in two decades and forecasters warned that life-threatening cold was heading eastward, officials in Chicago and other districts said schools would be closed on Monday.
Icy conditions snarled travel across the Midwest and thousands of flights were canceled or delayed, days after the Northeast was hammered by the first winter storm of the season.
"The coldest temperatures in almost two decades will spread into the northern and central US today behind an arctic cold front," the National Weather Service said on Sunday. "Combined with gusty winds, these temperatures will result in life-threatening wind chill values as low as 60 degrees below zero (Fahrenheit/minus 51 degrees Celsius)."
In weather that cold, frostbite could set in on uncovered skin in a matter of minutes, experts warned. Minnesota Governor Mark Dayton ordered all public schools in the state closed on Monday to protect children from dangerously cold weather.
