A powerful polar vortex is set to cover the Big Apple in six inches of snow Sunday afternoon, ushering in bone-chilling low temperatures with wind chills as low as 15 degrees below zero that will continue into next week.
New York City will be under a winter weather advisory from 1 p.m. through Monday morning, as temperatures drop below freezing and up to a half-foot of snow falls over the tri-state area.
“The temperature will drop and we will see a wintry mix before we start getting heavy snow,” Marissa Lautenbacher, a meteorologist at the Fox Forecast Center, told The Post.
“Once the snow starts falling, the temperature will basically drop like a rock,” Lautenbacher added.
New Yorkers should take off their gloves and scarves before the afternoon, as freezing rain will turn to heavy snow by dinnertime Sunday — turning the roads into a mess in time for the evening commute.
“Heavy snow will start falling mid to late afternoon, perhaps around dinner time, and will stop during the overnight hours. “It will be very cold, with a low of 17 degrees,” Lautenbacher added.
While the five boroughs will see between four and six inches of snow, coastal areas of Connecticut and Long Island should expect between three and five inches.
Meanwhile, a state of emergency was declared in New Jersey ahead of the storm, where parts of the Garden State may be covered in up to 10 inches of snow.
Up to half a foot of snow will also cover Washington, D.C., and the I-95 corridor from Philadelphia to Boston.
“I would advise people, basically, if they have anything to do today, do it early, and then … stay home for the rest of the afternoon,” Lautenbacher said.
The snow will stop falling around 1 a.m., but will continue, thanks to bone-chilling temperatures in the lows, which are expected to continue through Wednesday.
Bitter winds will also bring temperatures down to minus 15 degrees, according to the National Weather Service.
Gusts of up to 20 mph are expected to hit the area through midweek, prompting city officials to issue a “Code Blue” cold weather alert.
New York Mayor Adams on Saturday warned New Yorkers not to plan for widespread disruption on the roads, urging locals to use public transportation and limit their trips.
With the Martin Luther King Jr. holiday, schools will be closed and plows will be able to clear roads better, Adams said.
