A wintry blast is expected to send a chill through a swath of the US this week — possibly bringing record-breaking cold air and a few flurries to the Big Apple, forecasters predict.

“This is not the norm by any means,” Accuweather senior meteorologist Tom Kines said Monday. “This is about as cold as it gets for this time of year.”

For New York City, the bitter cold is expected to roll in by the evening rush Tuesday.

Temperatures early in the day will be near 50 and the city can expect some rain — but the mercury will drop into the mid-30s as the day goes on, Kines said.

“Tomorrow’s one of those days where you dress for the evening hours, not the morning hours,” Kines said. “Don’t be fooled. It’s not out of the question that before the precipitation ends, it will end as a little bit of snow. It won’t accumulate, but it will be a signal that this next air mass that comes in means business.”

Tuesday night, temperatures in the city could dip into the low 20s — potentially breaking a record low of 22 set on that day in 1873.

“You throw in the wind and it’s going to feel like the teens out there,” Kines said.

New Yorkers should break out their parkas Wednesday as well, when the temperature is only expected to reach a high of 34, according to Kines.

The lowest high temperature ever recorded that day was 33 degrees, set back in 1911.

“That’s another indication of how cold this air mass is,” Kines said. “It could end up being the coldest November 13 that we’ve ever had.”

No snow is expected to stick in the Big Apple, but in the northern part of the Hudson Valley, there will be a “small accumulation,” the meteorologist said. Western New York, the Adirondacks and the mountains of New England could see at least 6 inches, maybe a foot, he added.

Nationwide, 148 daily record lows are expected to be “broken, tied, or come within 1 degree” between Tuesday and Thursday, the National Weather Service tweeted.

In Chicago, the wintry weather was already causing problems Monday morning. An American Eagle flight slid off the snow-coated runway as it landed at Chicago O’Hare Airport from Greensboro, North Carolina, around 7:45 a.m., according to ABC 7. No injuries were reported.

Up to six inches of snow is expected to fall in parts of the Chicago area, and a winter weather advisory is in effect for the region.

The cold front was passing through Oklahoma on Monday morning “with post-frontal gusts of 35-50 mph,” the weather service’s Tulsa branch wrote.

Even the Deep South won’t be exempt from the cold.

“Check out our high temperature tumble due to a frontal passage Monday night,” the National Weather Service in Birmingham, Alabama, tweeted. “Between 25-30 degrees difference Monday-Tuesday. We continue the slide Tuesday night with lows in the 20s, some pockets of upper 10s!”

Kines added, “The air mass that’s coming in, it’s an equal opportunity air mass. Everyone’s gonna get cold.”
