The new year's winter weather is threatening icy shock waves for the eastern two-thirds of the country.
The first cold blast set records Thursday in Minnesota and is expected to strike the Eastern U.S. on Friday with possibly single-digit temperatures in places. Boston's reading could fall to zero.
A second blast is expected to move from the Great Plains and Midwest on Sunday and Monday and into the East on Tuesday. The National Weather Service called for below-normal temperatures, high winds or heavy snow for most places east of a line from central Montana to Houston. Some meteorologists predicted subzero wind chills, possibly as far south as Atlanta.
But both cold shots should be fleeting with subsequent temperatures warming up quickly.
Meanwhile, New York Gov. Andrew Cuomo says some major highways around New York City will be shut down as a coastal storm brings snow and blizzard conditions to the region.
Cuomo says Interstate 84 in the Hudson Valley will be closed to commercial traffic starting at 5 p.m. Thursday and to all traffic at midnight. He says the Long Island Expressway will be closed at midnight on most of the island. The New York Thruway also will be closed from Albany south at midnight.
Cuomo says plans are for the highways to reopen at 5 a.m. Friday, but a decision will be made by 4 a.m.
The governor also declared a state of emergency Thursday and urged people to "seriously consider" staying home.
He says mass transit isn't expected to be hampered. (AP)
