The coldest air mass for nearly 3 years now settles over New York and Boston

Since then, the temperature has dropped and it will remain dangerously cold throughout the day in the region, leaving major cities like New York and Boston with the frigidest daytime air mass in nearly three years.

As the sun rose over New York on Tuesday morning, it had already plunged into the teens from a starting point of 23 degrees. And even if the sun tries to heat the country’s most populous city, the temperature will try to get back to 20.

“This afternoon’s highs will have a hard time pulling out teens and 20s for most places, with single-digit numbers found in northern New England,” the Weather Prediction Center said.

In Boston, the temperature fell to single digits on Tuesday morning and will barely make it back in adolescence in the afternoon.

“Dangerous cold in southern New England today as arctic air invades,” the Boston office of the Nation Weather Service said on Tuesday.

The worst part is that it is even colder than the thermometer reading.

Why is it even colder

New York and Boston are both flirting Tuesday morning with “similar” temperatures around or below zero.

“Feel like” refers to how temperature and wind work together to make it feel cooler than it would be without wind; it is also known as wind chill.

As the wind increases, it draws heat from the body, lowering the temperature of the skin – and eventually the internal temperature of the body. Therefore, the wind makes him “feel” much colder.

Strong winds will continue to make you feel colder throughout the day Tuesday before easing overnight.

“The high winds will add another bite to the cold snap, with widespread wind chills below zero across the region and as low as 40 below zero in northern Maine,” the forecasting center said.

Frostbite on exposed skin can occur in as little as 10 minutes when wind chill temperatures drop this low, said the weather service office in Gray, Maine.

More than 6 million people were on wind chill alert Tuesday morning from New York to Maine, where the “similar” temperature was putting their lives at risk.

Although it may take longer to develop frostbite in the more southerly states that will be slightly warmer, it is very important to always take precautions to ensure your safety.

“Venturing into this cold weather requires a plan to stay safe for you and your pets,” CNN meteorologist Chad Myers said. “Shorter rides, lots of layers, and a cold weather kit for your car are always things to consider. Even indoors, it’s time to avoid freezing pipes. “

Are you wondering where this cold comes from? Here’s a clue: It’s cold and freezing and sits above the Arctic Circle.

Indeed, the air parcel in Boston was traced to Utqiaġvik (formerly Barrow), Alaska, by meteorologists from the Boston Weather Service office.

“Fortunately, this breath of cold air won’t last long as more seasonal temperatures in the 1930s and 1940s will arrive on Wednesday afternoon,” the Prediction Center said.

But even that relief might be brief.

“Even though there will be a few brief warmer days,” Myers said, “the general pattern shows that the jet stream and associated cold fronts are arriving from the Arctic for at least the next two weeks.”

This will keep most temperatures in the eastern US well below average and in the western US well above for the remainder of this month.

“The duration of the arctic explosion is also important and the cold air itself,” Myers explained. “This kind of prolonged cold snap puts a strain on everything from city services to your water lines.”
