"While frigid air is already in place, yet another brutal shot of
arctic air will grip the entire eastern two-thirds of the nation
through Saturday. The last time severely low temperatures froze a
large swath of the nation was in 1985. New waves of cold air will
continue to spread southward from Canada in the coming weeks, possibly
causing this winter also to rival the bitterly cold winters of 1982
and 1977-78. Some of the greatest temperature departures from average
this winter may yet to come."
