Bone-chilling, record-breaking cold is forecast for Monday, with even Twin Cities residents waking up to minus 25, or below, according to the MPR News Updraft blog.
Temperatures for the Upper Midwest are making national headlines. The Associated Press reports cold temperature records are likely to be broken, thanks to what one meteorologist calls a "polar vortex."
That means frigid air from the North Pole will be pulled through the U.S. by a counterclockwise rotation of cold, dense air.
"All the ingredients are there for a near-record or historic cold outbreak," said Ryan Maue with Weather Bell. "If you're under 40 (years old), you've not seen this stuff before."
The cold blast will sweep through parts of New England, where residents are still digging out from a storm that dumped two feet of snow in some places. Temperatures will be in the 20s early this week in Atlanta and other cities unaccustomed to cold weather.
Maue said the duration of the cold spells is more significant than the deep dive.
The Arctic blast will freeze over the Great Lakes and other bodies of water, meaning frigid temperatures will likely last the rest of winter, Maue said.
"It raises the chances for future cold," he said, adding it could include next month's Super Bowl in New Jersey. Strong northwest winds counteract any warming effect from the Gulf of Mexico.
Ken Simosko, a meteorologist from Bismarck, said it would take five minutes to get frostbite in minus 50 degree conditions.
"We usually don't call something 'life threatening,'" he told FoxNews.com. "But yes, we want people to know that this is very much a life-threatening event."

The Duluth News Tribune reports homeless shelters are redoubling outreach efforts. They are over capacity, but not turning anyone away.
Joel Kilgour, an outreach worker for Loaves and Fishes, says at least two homeless Duluth residents area suffering from frostbite that may require amputation.
Advocates for homeless people are asking the public to send them tips on where people are living outside, including in cars or campgrounds.
"We have a small team and Duluth is a big place," Kilgour said. "There are warm places to sleep."
The hotline number is (218) 461-8505.
