Ready for some serious cold?

The planet's most extreme cold air will be barreling into the central and eastern United States this coming weekend "like a wrecking ball," said Weather Trader meteorologist Ryan Maue in a post on X on Dec. 9.

Maue called it a "textbook 'Polar Vortex' mega-dump of western Canadian cold."

"Some of the coldest, if not the coldest, temperatures across the entire globe will cover the central and eastern U.S. over the weekend and into early next week," said climatologist Judah Cohen, a research scientist at MIT, in an email to USA TODAY.

"It also seems that the most expansive and continuous area of below normal temperatures across the globe will extend from Alaska to the eastern U.S. this upcoming week," he said.
