The Big Apple will be more like the Big Icebox this weekend.

An arctic cold front packing dangerous winds of up to 60 mph could make it feel like it’s 20 below zero by Sunday — the coldest wind-chill factor since 1993’s “Storm of the Century,” forecasters warned.

“You better snuggle up,” AccuWeather meteorologist Tom Kines said, noting the arctic blast will blow through after another snowstorm slams the already hard-hit Northeast this weekend.

The blizzard to the north will skirt the city Saturday into early Sunday but could leave up to 3 inches of snow on the ground in the metro area.

Saturday’s high will be about 35 with a low of 17, but by Sunday morning conditions will be downright dangerous.

The thermometer will plummet to 6 degrees or lower.

“When the winds pick up Saturday night, that’s the signal” the front is crashing through, Kines said.

The wind will build as the thermometer drops, which means brave souls venturing outdoors Sunday morning should dress for the North Pole — with plenty of layers and no skin exposed.

“Sometimes we forget about our ears and our nose,” Kines said, urging people to bundle up outside.

But some New Yorkers said they would ride out the frigid temperatures indoors, and ward off the chill with some hot food or a bottle of booze.

“I’m going to go home, eat soup and stay warm. I just want to get home to the heat,” Eddie Girado of Cobble Hill, Brooklyn, said while leaving work on the Upper West Side.

Hollye Hudson, another Brooklyn resident, said, “I’m probably just going to buy a bottle of wine and stay inside.”

Shavkat Yenileev declared: “I’m going to drink a lot. That’s all. It’s going to keep me warm. I live in Brighton Beach. All of Brighton Beach will be drunk!”

The relatively light snowfall in the city will still make roads treacherous as the gale-force winds kick up powder over bridges and highways.

The wind will continue into Monday, making temperatures again feel as low as minus-20 and blowing with enough force to bring down tree branches and power lines, AccuWeather warned.

Forecasters said the wind chills could be colder than in March 1993, when the so-called Storm of the Century, or ’93 Superstorm, swept across the East Coast from Alabama to Canada, killing more than 300 people before it headed out to sea.
