As millions of Americans hunker down for the winter storm, 17 states and Washington, D.C., have declared states of emergency.

On top of heavy snow, forecasters and public officials are worried about slick, icy roads and the potential for sleet and freezing rain to spark power outages.

A severe winter storm is expected to bring a glaze of ice, dangerously cold temperatures, and potentially a foot of snow to Oklahoma starting Friday.

Dry weather hangs on through most of Saturday as well before the winter storm arrives late day. Sleet and snow will start up by at least Saturday evening (some may fall in spots by the late afternoon out west.) Not expecting any big travel issues until we get into Saturday night as the deeper moisture arrives.
