Raleigh could deal with a sleet storm but at least sleet but that will be less burdensome than freezing rain.
Charlotte could see significant sleet and freezing rain Saturday. Also, some sleet and freezing rain could bleed south in to north Georgia and northern South Carolina. Some freezing rain may make it down to the north and northeast suburbs of Atlanta by Saturday morning.

Low pressure sliding up to the Canadian Maritimes will funnel some very cold air into the Northeast Friday.
Snow will linger in northern Maine with several inches expected.
Lake-effect snow will intensify off of Lakes Erie and Ontario. Parts of the southern Tug Hill will see over a foot of snow. Significant amounts may also pile up along the south and southeastern shore of the Lake Ontario. A waterspout wrapped in snow was spotted just east of Rochester, N.Y., on Thursday.
Friday highs will range from the single digits across northern portions of New York, Vermont and New Hampshire to the 30s in Virginia. wind chill temperatures will be well below zero.
On Saturday, the storm will brush by to the south.
The snow will fall south of the Mason-Dixon Line with the heaviest across southern Virginia where accumulations of over 6 inches are likely. Cities like Danville, Richmond, and even Norfolk should prepare for significant snow.
The southern suburbs of Washington could be brushed by a bit of snow on the extreme northern end of the storm.
