Major Storm Spreading Across Nation's Midsection

(Undated) -- A huge winter storm system is moving across the middle of the country and is expected to create a holiday travel nightmare this week. Several hundred flights have already been canceled at Dallas-Fort Worth International Airport and there have been several fatalities from accidents in Texas and other areas of the nation's midsection. Forecasters are warning the winter storm could cause flight delays and ice-laden roads for the millions of people set to travel for Thanksgiving. DFW had more than 600 flights canceled on Sunday and over 300 more flights have already been shelved today.
