Quick surges of frigid and mild air will produce dramatic temperature swings from one day to the next in the East.
The temperature swings of 25 to 50 degrees in a matter of hours will make it very hard for some people adjust and can lead to melting and freezing cycles that cannot only rupture water mains but also cause ice to form following bouts of melting snow.
During the cold days, when the wind is blowing, combined with other atmosphere conditions, RealFeel® temperatures will be 10 to 30 degrees lower than the actual temperature.
Air blasting southward from eastern Canada on Friday will send temperatures down to their lowest levels since January 2009 in many locations from New England to part of the mid-Atlantic.
