Another massive winter storm is forecast to pummel the southern and eastern U.S., with impacts from Texas to the Carolinas.

Snow and icy conditions threatened to paralyze parts of the U.S. South from Texas to Alabama on Thursday, as officials closed schools, canceled or delayed flights and warned residents in some of the worst-hit areas to stay off roads as a winter storm moves east.

Brutal cold will open the door for a winter storm to take a somewhat unusual track through the South and create treacherous conditions.
