231 million blasted with arctic air as 'dangerously cold' temps invade US

"Dangerously cold" wind chills of 15-30 degrees below zero are likely in the Upper Midwest, while heavy lake-effect snow measuring multiple feet could impact travel across the Great Lakes region.

BUFFALO, N.Y. – The first arctic outbreak of the season is allowing temperatures to plunge across the eastern half of the country, creating "dangerously cold" wind chills of 15-30 degrees below zero in the northern Plains and Upper Midwest. 

Arctic air has flooded in from Canada during the Thanksgiving holiday, allowing the cold air to travel as far away as the Southeast.

Well over 230 million Americans will remain with below-average temperatures into the start of the workweek.

According to NOAA's Weather Prediction Center, wind chills should fall well below zero across the northern Plains and Upper Midwest. 

Areas of the Dakotas and Minnesota will see dangerously cold temperatures that could cause hypothermia and frostbite if unprotected skin is exposed. Some areas will drop to between -30 and -40 degrees when factoring in the wind chill.

In the Northern Plains and Upper Midwest, temperatures could drop below -10°F, with wind chills making it feel even colder to around -20°F or lower. The coldest days would likely be in the Sunday-Monday timeframe.

Farther south into the Midwest, lows may fall into the teens, and wind chills could dip near -10°F. This could bring the coldest air of the season so far for many areas. 

The winds will drastically increase as a powerful arctic front powers through the region on Monday-Tuesday.

Travelers in these regions should be sure to have a winter survival kit.

The Southeast and South-Central U.S. should also prepare for chilly conditions from late November into early December. 

Many spots might see their first freeze of the season if they did not already this past cold spell.
