On the back of a powerful winter storm hitting the Arctic Circle, another wave of arctic air is rushing into the United States.
On Thursday morning, wind chills reached below freezing in places, with low temperatures in the single digits in parts of the Dakotas and upper Midwest.
Cold air is pushing in behind an arctic front, affecting hundreds of millions of people in the eastern part of the country.
According to the FOX Prediction Center, maximum temperatures will be 20 to 30 degrees below normal.
With winds blowing in excess of 80 mph for millions of people, wind chill values will become dangerous for some.
Areas like New York City may feel warmer starting Thursday morning, but temperatures will continue to cool during the day.
Low temperatures will be in the 20s along I-95 and in the 10s in the interior Northeast.
“These cold temperatures extend all the way south,” FOX Weather meteorologist Britta Merwin said. “I mean, we have a lot of friends.”
Cold weather will return across the Southeast as well, with highs expected to be 10 to 20 degrees below average, especially on Friday.
Friday morning could even see record-low temperatures in parts of the Carolinas.
Record or not, Friday morning's low temperatures will be in the teens for millions of people from Alabama to Georgia to Mississippi.
“This is a good time to check your home's carbon monoxide monitor and make sure your fireplace is cleaned to stay warm in a safe way,” Merwin advised.
The warm-up is scheduled to arrive in the eastern United States early next week.
