A winter storm warning issued by the National Weather Service at 2:13 p.m. on Thursday, Jan. 9, provided further insight on the storm expected to sweep through Western North Carolina beginning on Friday, Jan. 10.
The warning, in effect from 7 a.m. Friday to 7 a.m. Saturday, Jan. 11, applied to a long list of counties and areas in WNC as well as portions of northeast Georgia, Upstate South Carolina and the N.C. Piedmont.
Impacts included accumulation of snow and ice, which will make many roads "treacherous and impassable." The weight of this snow and ice may also cause scattered power outages as it accumulates on tree limbs and power lines.

On Friday night, there is a 90% chance of precipitation. Snow will continue with the potential for mixed sleet until 8 p.m. at which point only snow is expected. New snow and sleet accumulation of around an inch is possible.
NWS Meteorologist Trisha Palmer told the Citizen Times that meteorologists are still looking into whether warmer air may mix in with the storm, causing sleet and other precipitation.
"We're trying to figure out if we might be seeing some freezing rain that might mix in as well, and that'll end up bringing some of the snowfall totals down if it does," Palmer said.
How much snow will Hendersonville get?
Precipitation amounts in Hendersonville are predicted to be slightly higher. Palmer said that, as Asheville is in a "rain shadow," there can be slight differences in precipitation amounts even though the cities are close together.

"There might be a slight difference, but it's going to be very close."
NWS forecasts call for a 90% chance of precipitation on Friday, with snow before 5 p.m., then snow potentially mixed with sleet. During the day, between 1-2 inches of snow and sleet is expected.
On Friday night, the chance of precipitation raises to 100%, with snow and sleet expected, returning to only snow expected after 10 p.m. New snow and sleet accumulation of 1-3 inches is possible overnight.
Will flights be affected by the snow, winter storm?
Palmer said that the NWS cannot speak to de-icing operations and other measures that may be taken by airports to mediate the effects of winter weather. However, she was able to say that lower visibility and lower ceilings moving in could cause flight issues.

"The more severe restrictions would come in after that 24 hour period, so later in the afternoon," Palmer said. "So yes, there would certainly be more significant restrictions flying in ice and snow. Especially ice is certainly an issue for pilots, because it would weigh down the airplane."

Are power outages expected?
Palmer said that many trees in affected areas were weakened by Tropical Storm Helene, and are therefore more likely to cause outages with fallen limbs despite measures taken by power companies to avoid these issues.
"They do a really good job of trying to get the limbs back from the power lines," Palmer said. "But this fall, as we all well know, it was a horrific time for everybody, and there's just a lot of trees that are very weak."
Certain areas are more likely to be affected; Palmer added that further north, where more snow and less sleet and freezing rain are expected, there will likely be less impact.
