Freezing rain and drizzle is disrupting travel from Central Texas to the Great Lakes, with ice-glazed roads leading to hundreds of traffic accidents, including one in Kentucky that killed a toddler. Hundreds of flights were canceled Wednesday at Dallas-Fort Worth International Airport as 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 another area of freezing rain was expected to hit south-central Pennsylvania and western Maryland, the National Weather Service said.
