A swift-moving winter storm dumped up to 4 inches of snow on the Big Apple, in the city’s largest snowstorm in years — knocking out power, grounding flights and closing schools in the nation’s biggest public school system. 

The powerful nor’easter began dumping snow at a rate of 1-2 inches per hour during the morning commute before tapering off in the early afternoon, according to the National Weather Service (NWS).

Central Park recorded 3.2 inches of snow, which is less than the approximately half a foot predicted but still the highest daily snowfall in more than two years. LaGuardia Airport (LGA) reported 3.3 inches while John F. Kennedy Airport (JFK) totaled 4.2 inches, and Newark Airport pulled in 4.9 inches, a Fox Weather spokesperson told The Post Tuesday. 

The biggest dump in the NYC-area was Coney Island, which saw around 6 inches of snow, and the Long Island Sound, which saw 11.8 inches. Most of the Island, however, saw only 3 to 6 inches. 

Meanwhile, the highest recorded snowfall in the tri-state area was recorded in Farmington, Conn, which clocked in at a whopping 15.5 inches. West Hartford came second, leaving residents with 15.2 inches, Fox Weather meteorologist Cody Braud told The Post.

Hoboken brought in much less with only 4.8 inches, according to the Fox Weather spokesperson. 

The Jersey Coast also only saw about four to five inches, with Jersey City reporting even less. 

The Lower Hudson region around the city of Newburgh also saw about 10 to 12 inches of snow, but further south in Westchester, Poughkeepsie, just five inches was recorded.

Despite moving through the region quickly, the winter storm still caused chaos. More than 1,100 flights within, into or out of the United States were canceled — including more than a third (37%) of flights scheduled to depart LGA and almost one in five (18%) scheduled to take off from JFK, according to Flightaware.  

Strong winds also left more than 7,000 people without power in New Jesery, according to PowerOutage.us, a website that tracks outages across the country.

More than 5,000 people across New York were also reporting power outages later Tuesday.

In the Big Apple, Con Edison said on Monday it secured 250 more crews to respond to any power disruptions caused by the storm.

But that did not seem to help students and teachers who were trying to sign on for remote learning on Tuesday, only to find “service unavailable” messages.

“Just give them the day off, people!” “Today Show” meteorologist Al Roker exclaimed on the show.

To prevent any major accidents, the state has also “pre-deployed” 1,800 plows throughout the city and Long Island, Hochul said Tuesday morning.

Thousands of sanitation workers worked overnight to put salt on “every street, every highway, every bike lane in the city,” Department of Sanitation Commissioner Jessica Tisch said. 

Meanwhile, the snowstorm could also affect turnout in the nail-biter special election for former Rep. George Santos’ congressional seat.

“As close as this race has been and after the millions of dollars that have been spent, the election might be decided by the weather gods,” said Lawrence Levy, dean of the National Center of Suburban Studies at Hofstra University and a longtime observer of Long Island politics.

Some said the storm could give Tom Suozzi, a former three-term congressman, an edge as thousands more Democrats turned out during the nine days of early voting in the nail-biter race.

But conservatives angered by issues such as the festering border crisis and displeasure with President Biden might be more motivated to shovel out their car out of snow and ice and drive to the polls to vote for Mazi Pilip, a Nassau County legislator.

“It could be a problem for both parties. There’s a diversity of opinion in both parties over the impact,” Levy said.

Conditions are then looking better for Valentine’s Day – but wet weather may come back soon after.

“After today, it’s going to be pretty quiet,” Braud said.

Wednesday will remain in the mid to upper 30s and will be mostly sunny, though certain areas may see some lingering clouds.

By Thursday night, the area “may have a quick bout of rain,” Braud said, but “it will be out of here by Friday.”

Going into the weekend, Braud said, “There could be another shot” for snow, depending on how much temperatures drop.

But even if there is, he said, it would not bring the same snow totals as the storm on Tuesday.
