Coldest November Weather in Decades Infiltrates Wyoming to Texas From the North Pole

Temperatures plunged by as much as 60 degrees Fahrenheit across the Rockies and Plains early this week, and the unrelenting cold has remained entrenched across these areas all week.

It has been as much as 30-50 degrees below normal this week from Wyoming and Colorado all the way southward to Texas.

"This is exceptional cold," AccuWeather.com Senior Meteorologist Henry Margusity said. "It's the coldest air we've seen in decades during November."

The cold air has come straight from the polar region, according to Margusity.

"The remnants of Nuri grew into a record storm over the Bering Sea, and then it sent warmth into the polar region," Margusity said.

As a result, the cold was unleashed southward from the North Pole. Margusity gave the analogy of squeezing a stress ball. Since cold air is denser than warm air, it oozed out of the pole much like how a stress ball will expand when squeezed.
