CONCORD, N.H. - The first full day of winter brought a wild mix of weather across the nation Sunday: ice and high wind in the Great Lakes and New England areas, flooding in the South, snow in the Midwest, and record-shattering temperatures in the 60s and 70s along the Mid-Atlantic, including in Philadelphia.
Snow and ice knocked out power to 440,000 homes and businesses in Michigan, northern New York, and northern New England, and also left more than 475,000 people without electricity in eastern Canada. It could be days before the lights are back on everywhere.
At least nine deaths in the United States were blamed on the storm, including five people killed in flooding in Kentucky and a woman who died after a tornado with winds of 130 m.p.h. struck in Arkansas. Five were killed in Canada in highway accidents related to the storm.
The icy weather was expected to make roads hazardous through at least Monday from the upper Midwest to northern New England during one of the busiest travel times of the year.
As of midafternoon, more than 700 airline flights had been canceled and more than 11,000 delayed, according to the aviation tracking website FlightAware.com.
High-temperature records for the date fell for the second straight day in the Mid-Atlantic states because of a mass of hot, muggy air from the South.
In New York's Central Park, the mercury reached 70 degrees, easily eclipsing the previous high of 63 from 1998. Records were also set in Wilmington (67), Atlantic City (68), and Philadelphia (67). Washington tied its 1889 mark at 72.
Temperatures were expected to return to normal by Monday night and Tuesday, dropping back into the 30s.
Heavy snow in Wisconsin forced dozens of churches to cancel Sunday services. Milwaukee got about 9 inches, Manitowoc 7. Ice and snow in Oklahoma were blamed for three traffic deaths on slick roads.
In New York's St. Lawrence County, almost 2 inches of ice had accumulated by early Sunday, coating tree limbs and power lines, and a state of emergency was declared to keep the roads clear of motorists.
Despite a glaze of freezing rain in Maine, plenty of shoppers ventured to the outlet malls in Kittery, Maine, on the last weekend before Christmas.
In Canada, crews struggled to restore service to those without power in Ontario, Quebec and New Brunswick. Toronto Mayor Rob Ford called the storm one of the worst in the city's history. Passengers were stranded at airports from Toronto to St. John's, Newfoundland.
In Kentucky, five people were killed in flooding caused by the storm system. The bodies of three people were pulled from Rolling Fork River on Sunday after their vehicle was swept away by floodwaters, a fourth person drowned in Carroll County after a four-wheeler overturned in high water, and a body was discovered in Ballard County near a car abandoned in a flooded ditch.
In Arkansas, authorities said Sunday that a woman was killed after a tornado with winds of about 130 m.p.h. struck in St. Francis County on Saturday. A man found in a field was hospitalized in serious condition, while the woman's 3-year-old granddaughter and 25-year-old daughter were treated at a hospital.
