Dangerously cold wind chills continued into Christmas morning across much of the United States after a nearly week-long winter storm dropped temperatures to life-threatening lows, triggered blizzards and coastal flooding, and left no electricity to hundreds of thousands of homes and businesses.
Blizzard conditions persisted across the Great Lakes on Sunday as frigid temperatures gripped the eastern two-thirds of the country, with some large cities in the Southeast, Midwest and East Coast registering their coldest Christmas in decades.
More than 55 million people remain under wind chill alerts this Sunday morning, and there are frost warnings in the south of the country.
Temperatures are expected to pick up later in the week, with a very welcome upward trend and above normal temperatures.

Power outages
Nearly 175,000 US homes and businesses were without power as of 8:30 am ET, many of them in Maine and New York, according to PowerOutage.us.
Since the start of the storm, the number of outages has at times exceeded a million customers.
A power grid operator in at least 13 states in the eastern half of the country asked customers to save energy and set thermostats lower than usual from early Saturday until 10 a.m. Sunday because usage it was forcing capacity.
The operator, PJM Interconnection, serves some 65 million people in all or part of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and the District of Columbia, and warned that blackouts could occur if the load was excessive.

What to expect as the storm slowly weakens and hazardous conditions continue
Strong winds behind the arctic cold front that pushed through this week will lead to lake-effect snow and blizzard conditions at times across portions of the Great Lakes this Sunday.
Blizzard warnings, winter storm warnings, and winter weather advisories cover much of the Upper Midwest, the Great Lakes region, and the Ohio Valley.
An additional 8 to 16 inches of lake effect snow is possible.
The storm system is expected to gradually weaken as it rises over southeastern Canada, moving slowly over the next couple of days and pulling arctic Canadian air down over much of the eastern side of the country.
The arctic gust will slowly taper off towards Monday.
According to the National Weather Service, low temperatures combined with dangerous wind chill will create a life-threatening hazard for stranded travelers, people who work outdoors, livestock and pets.
"In some areas, being outdoors could cause frostbite within minutes," the Weather Service warned.
As frigid air continues to batter the warm waters of the Great Lakes, lake-effect snowfall and blizzard conditions are expected to continue, but gradually fade.
Still, the strong winds gusting to 60 mph that accompany snow downwind of the Great Lakes will continue to create extremely hazardous road conditions.
By Christmas night through Monday, another low-pressure system from the Pacific will deliver the next surge of moisture into the Pacific Northwest and then into northern California, according to the Weather Service.
