Polar Vortex Triggers Record Cold in Much of US
Thousands of schools across the eastern and southern United States were closed Tuesday as a bitter cold front moved into the area after freezing the midwestern section of the country.
Forecasters said temperatures will plunge well below minus 10 degrees Celsius in Washington, D.C., New York, Philadelphia and Boston, while the wind chill, which is the temperature feels like during a strong wind, will be far lower.
The frigid weather is also reaching into the so-called Deep South, including Florida and southern Texas, which usually enjoy moderate temperatures during the cold weather season.
Authorities have decided to close schools to keep children safe from exposure to the extreme cold, which could lead to frostbite within minutes if skin is left exposed.
Life-threatening cold paralyzed much of the Midwest on Monday, forcing airlines to cancel thousands of flights and disrupting rail service. Air temperatures were minus 23 Celsius in Chicago, Indianapolis and Minneapolis -- and minus 29 in International Falls, Minnesota, colder even than the South Pole.
Forecasters said the widespread cold is caused by a rotating vortex of cold dense air being pushed south from its normal place in northern Canada.
More normal temperatures are forecast for later this week.
