A winter storm barreled out of the U.S. Midwest on Thursday, creating misery for holiday travelers, knocking out power to hundreds of thousands of people and breaking snowfall records. Airports serving Cincinnati, Cleveland, Toronto, Chicago and Atlanta reported weather-related delays, as up to 2 feet (60 cm) of snow blanketed a region from southern Missouri to western Tennessee and north into Ontario, Canada. Dozens of motorists were stuck on Indiana highways in the blowing snow, waiting to be rescued as temperatures dropped toward zero degrees Fahrenheit (-18 C). "These are places not used to snow," said Alden Taylor, a spokesman for Indiana Emergency Management. A heavy layer of snow collapsed the roof of a house in central Crawford County. The four people inside were rescued and not hurt, he said. Oklahoma had four weather-related traffic deaths and three deaths were reported in Ohio where an ice storm preceded a foot-deep (30 cm) snowstorm and knocked out power to more than 300,000 customers, local utilities said. --More 2149 Local Time 1849 GMT
