Twenty states, from Texas to Delaware, were on alert Friday for snow and ice as the storm continued to move across the South.

Snow will turn into sleet and freezing rain along parts of the Southeast, as well as southern Arkansas, the weather service reported. Forecasters warn that icy conditions, between a tenth and a quarter inch of ice, will make travel dangerous for many. Power outages and downed branches are also a concern.

Millions of residents across the Southern U.S. woke up to a rare chance to bust out the mittens and snow pants thanks to a cold snap that dumped snow in their backyards.

Snow is no longer falling over most of North Texas after the first winter storm of the season. The National Weather Service dropped a winter storm warning early Friday morning, and let a winter weather advisory expire at 12 p.

An ice threat with Winter Storm Cora remains into tonight before lighter snow moves into the Mid-Atlantic and Northeast. Here is the timing for what is left.

Winter Storm Cora is sweeping through the Southeast and Ohio Valley, delivering a mess of snow and some ice from Tennessee to the Carolinas and Virginia, including Charlotte and Raleigh. The wintry mess is snarling travel and in some cases icing could be heavy enough to cause power outages and tree damage.
