The Concrete Jungle is about to feel like an Arctic tundra.

Bone-chilling temperatures will make staying outdoors a threat to life and health this weekend in the New York metro area, meteorologists and officials said.

According to the National Weather Service, New York City and surrounding areas are likely to experience the coldest temperatures of the year so far, especially Saturday night into Sunday. The agency has issued an extreme cold warning for that period.

NWS meteorologist David Stark said an “Arctic cold front” will move in Saturday morning, bringing a brief window of snowfall before the temperatures start to plummet.

“We're going to start the day in the lower 20s, and then it looks like by early evening we could be down [to] around 10 degrees,” he said.

Lows are predicted to be around 5 degrees by early Sunday morning. They’ll be made all the worse by high gusts.
