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.

A low-pressure system is moving across the country, delivering rain, snow, and ice to much of the southeast. This same system will be making its way along the east coast early this weekend, bringing a chance for accumulating snow to the tri-state.

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.
