Johnson City, Tennessee – A high-impact winter storm is increasingly likely to affect the Tennessee–North Carolina border region from Wednesday, Jan. 14, through Friday, Jan. 17, bringing a strong threat of heavy mountain snow and dangerous travel conditions across the southern Appalachians.
According to the National Weather Service Weather Prediction Center, areas along the Tennessee–North Carolina border currently carry a 60 percent probability for severe winter weather impacts. The developing storm system is expected to track east from the Mississippi and Ohio valleys, drawing colder air into the Appalachian region and producing snow that may intensify due to elevation and upslope flow.
The greatest impacts are expected across higher elevations and mountain corridors, including Interstate 81 in northeast Tennessee, Interstate 26 from Johnson City into western North Carolina, and Interstate 40 through the Pigeon River Gorge. Snow-covered roads, reduced visibility, and difficult driving conditions are likely, particularly during overnight and early morning periods. Secondary mountain roads could become hazardous or impassable if snowfall rates increase.
Communities such as Johnson City, Kingsport, Bristol, Boone, Banner Elk, and areas near the Great Smoky Mountains may see prolonged snowfall, with locally higher accumulations at elevation. Gusty winds along ridge tops could lead to blowing snow and near-whiteout conditions at times.
Officials urge residents and travelers to begin preparations now, especially those planning to cross mountain passes later this week. TDOT and NCDOT caution that weather-related closures or travel restrictions are possible if conditions deteriorate.
Forecast confidence remains elevated given the strong probability signal. Winter storm watches, advisories, or warnings are likely to be issued as details on snowfall intensity and timing become clearer over the next couple of days.
