A dangerous Arctic blast is hitting large swaths of the country, bringing heavy snowfall and blizzard conditions along with dangerous wind chills.

As of Saturday night, 44 million people were under a winter weather advisory, with a wind chill warning affecting 29 million and a wind chill advisory in place for another 64 million, according to the National Weather Service.

In Des Moines, dangerous cold has settled in ahead of the Iowa caucuses Monday. Wind chills across the state ranged from minus 20 to minus 40 on Saturday.

Chicago, already with at least 5 inches of snowfall, is expecting another half-inch to 1½ inches through Saturday evening, and gusty winds may lead to blowing snow in rural areas.
