The first full day of Winter brought a wild mix of weather across the U.S. on 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.
Snow and ice knocked out power to 400,000 homes and businesses in Michigan, upstate New York and northern New England, and also left more than 400,000 people without electricity in eastern Canada. It could be days before the lights are back on everywhere.
As of midafternoon, more than 500 airline flights had been canceled and about 3,800 delayed, according to aviation tracking website FlightAware.com.
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.
In Arkansas, authorities said Sunday that a woman was killed after an EF2 tornado with winds of about 130 mph 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.
