A blizzard that buried parts of the Northeast in more than a foot of snow was followed Friday by icy temperatures that left roads as slick as skating rinks.
The storm left in its wake brutal winds and piles of wet snow — perfect conditions for black ice.
Widespread ice patches were expected in upstate New York, Long Island and in Connecticut, NBC New York reported, while a black ice alert was in effect Friday for all of New Jersey and schools were to be delayed 90 minutes to give buses time to get to pick up students safely.
Temperatures were well below freezing early Friday and were expected to stay bitterly cold throughout the day as blustery winds continued, forecasters said, with
Boston and many other Massachusettsareas cancelled school again on Friday. The city was hit by 14 inches of snow Thursday, and other parts of New England we buried under more than a foot and a half, according to NBC Boston.
At one point, more than 50,000 customers in Massachusetts were without power, the station reported.
Boston Mayor Martin J. Walsh said the snow emergency and parking ban would be lifted at 8 a.m. Friday.
"Thank you to the public who stayed off the roads today and allowed our crews to do their job during this significant storm," Walsh said. "We had more than 700 pieces of equipment out today during the height of the storm, and we will continue to work overnight to ensure that our roads are safe and ready for the morning commute."
The storm was blamed for at least one death in New York City, where a doorman died while shoveling snow.
Miguel Gonzalez, 53, of Bridgeport, Conn., died after falling through a glass window while shoveling snow in Manhattan's Upper East Side around 9:30 a.m. Thursday, police said.

The union 32BJ of Service Employees International said Gonzalez worked at the building for many years.
"Our thoughts and prayers are with his wife and children and all those who knew and cared about him, including his coworkers and the residents of his building," 32BJ President Hector Figueroa said in a statement.
In New Jersey, state police responded to nearly 200 vehicle crashes on Thursday.
The phenomenon known as "thundersnow" was reported in Rhode Island.
"It's pretty nuts here," Felecia White told The Associated Press as she and friends hunkered down in a restaurant in Newport, Rhode Island, waiting for the weather to improve. "Even with four-wheel drive, you can't do anything. You can't see across the street."

The total number of flight arrivals and departures canceled since Wednesday by the storm grew to 4,490 early Friday, according to website FlightAware.
The biggest impact was at LaGuardia, according to the site. New York Gov. Andrew Cuomo said Thursday that the nearly 700 cancellations there amounted to 60 percent of the airport's flights.
In Virginia, the driver of a tractor trailer was killed after the rig plummeted off a bridge and into the Chesapeake Bay. There were windy conditions at the time but no wind restrictions that applied to the truck, and authorities have not determined the cause of the accident, a Chesapeake Bay Bridge and Tunnel official said.
Although schools in Boston will remain closed Friday, the snow vacation will end for students in New York City and Philadelphia.
