An arctic blast that has gripped much of the United States this week, disrupting daily life and holiday travel for millions of Americans, was expected to produce the coldest Christmas Eve on record in several cities from Pennsylvania to Florida.
Temperatures are forecast to top out on Friday at just 8 degrees Fahrenheit (-13 Celsius) in Pittsburgh, the largest city in western Pennsylvania, surpassing its previous all-time coldest Christmas Eve high of 13 F, set in 1983, the National Weather Service (NWS) said.
The capital cities of Florida and Georgia — Tallahassee and Atlanta — were likewise expected to record their coldest daytime Christmas Eve high temperatures, while Washington, DC, was forecast to experience its chilliest December 24 since 1906.
The flurry of yuletide temperature records were predicted as a US deep freeze sharpened by perilous wind chills continued to envelope much of the eastern two-thirds of the nation into the holiday weekend.
The arctic cold combined with a "cyclone bomb" of heavy snow and howling winds roaring out of the Great Lakes region on Friday and into the Upper Mississippi and Ohio valleys to wreak havoc on power systems, roadways and commercial air traffic.
Extreme winter weather was blamed for at least five deaths on Friday.
Two motorists were killed, and numerous others injured, in a 50-vehicle pileup that shut down the Ohio Turnpike in both directions during a blizzard near Toledo, forcing an evacuation of stranded motorists by bus to keep them from freezing in their cars, officials said.
Three more weather-related fatalities were confirmed in neighbouring Kentucky — two from car accidents and one of a homeless person who died of exposure.
Freezing rain and ice from a separate storm in the Pacific Northwest made travel treacherous there as well on Friday.
From the Canadian to the Mexican border and coast to coast, some 240 million people in all were under winter weather warnings and advisories of some sort on Friday, according to the weather service.
The NWS said its map of existing or impending meteorological hazards "depicts one of the greatest extents of winter weather warnings and advisories ever."
With energy systems across the country strained by rising demand for heat and storm-related damage to transmission lines, as many as 1.5 million US homes and businesses were left without power on Friday, according to tracking site Poweroutage.us.
The disruptions upended daily routines and holiday plans for millions of Americans during one of the busiest travel periods of the year.
The American Automobile Association had estimated that 112.7 million people planned to venture 50 miles (80 km) or more from home between Friday and January 2. But stormy weather heading into the weekend likely ended up keeping many of them at home.
More than 5,700 US flights were cancelled on Friday, according to flight-tracking service FlightAware, while blizzard conditions virtually paralysed road travel in some regions.
The city of Buffalo and its surrounding county on the edge of Lake Erie in western New York imposed a driving ban, and all three Buffalo-area border crossing bridges were closed to inbound traffic from Canada due to the weather.
The severe weather prompted authorities across the country to open warming centres in libraries and police stations while scrambling to expand temporary shelter for the homeless. The challenge was compounded by the influx of migrants crossing the US southern border by the thousands in recent weeks.
Bitter cold intensified by high winds extended through the Deep South to the US-Mexico border, plunging wind chill factors to single digits Fahrenheit (minus 18 to minus 13 Celsius) in El Paso, Texas. Exposure to such conditions can cause frostbite within minutes.
