US: Wintry weather disrupts travel across the heartland

Freezing rain and drizzle is disrupting travel from Central Texas to the Great Lakes, with ice-glazed roads leading to hundreds of traffic accidents. Hundreds of flights were canceled Wednesday at Dallas-Fort Worth International Airport as freezing rain iced parts of Texas, Oklahoma, Missouri and Arkansas braced for an ice storm. More than half an inch of ice could accumulate in parts of the Ozarks through Friday morning, while a quarter- to a half-inch was expected in North Texas through Thursday, the National Weather Service said. Airlines had canceled more than 2,000 Thursday flights by Wednesday night, according to the FlightAware.com tracking site. About half of them were at the Dallas-Fort Worth airport, where temperatures were expected to top out above freezing only briefly late Thursday afternoon. DFW Airport is the biggest in the American Airlines network, and American had canceled 21% of its Thursday flights by Wednesday night, according to FlightAware.<br/>
