Bitter cold. Below-zero. Blizzard conditions.
Sorry, Northeast. But those are phrases you'll be using a lot Friday amid a monster storm.
And not just the Northeast, forecasters said. About one-third of the nation - approximately 100 million people in 22 states - is in the path this storm.
But the Northeast will be hardest-hit, the National Weather Service said.
"Heaviest snow will fall from central New York to the Massachusetts coast. Blizzard conditions are possible for eastern Long Island and the Massachusetts coast. Bitter cold will move into the Midwest and East following the storm," the Weather Service said.
The storm was expected to be at its fiercest between 8 p.m. Thursday and 10 a.m. Friday, according to CNN meteorologist Dave Hennen.
"Falling and blowing snow with strong winds and poor visibilities are likely," the Weather Service said. "This will lead to whiteout conditions making travel extremely dangerous. Do not travel."
Across the country, the nasty weather has snarled travel plans for many.
More than 2,200 U.S. flights had been canceled as of late Thursday night, reported FlightAware.com, which tracks cancellations due to weather and mechanical problems. It's not like things will suddenly clear up: the same website reports that some 1,300 flights already have been canceled in advance for Friday.
Thursday's most affected airport was Chicago's O'Hare, with more than 650 cancellations in and out and about the same number of delays. Newark's Liberty International Airport, New York's LaGuardia and Cleveland's Hopkins were also affected.
