The National Weather Service has issued a winter weather advisory for Scott County, effective from 3 p.m. Thursday afternoon until 7 a.m. Friday morning.
NWS meteorologists say one to three inches of snow accumulation is possible across the northern Cumberland Plateau Thursday afternoon and evening as a cold front changes rain showers into snow showers across the region.
The NWS's Morristown weather forecast office issued the advisory for Scott, Campbell and Claiborne counties. Further west, the NWS's Nashville WFO issued a winter weather advisory for Fentress and Pickett counties, which is scheduled to take effect at 1 p.m. A winter weather advisory issued by the NWS's Jackson, Ky., WFO is already in effect for McCreary County and the rest of southeastern Kentucky.
NWS-Jackson, Ky., was calling for up to an inch of snow accumulation in its forecast area, while NWS-Nashville forecasts up to two inches and NWS-Morristown up to three inches.
Radar returns Thursday afternoon showed rain coverage diminishing as the colder air pushed closer to the Cumberland Plateau. Communities in the greater Nashville area reported a brief changeover from rain to snow before the precipitation moved out. Further west, anywhere from a dusting to three-quarters of an inch of snow was reported in several West Tennessee communities.
Meteorologists warned that temperatures will plunge behind the arctic cold front. In its winter weather advisory, NWS-Morristown stated, "The cold air combined with brisk northwest winds between 15 and 30 mph tonight will produce wind chills between -5 and 5 degrees across the higher elevations and single digits elsewhere."
For Oneida, the NWS forecast called for a low of 11 degrees on Thursday night with an 80 percent chance of snow, followed by a high of 25 on Friday and a low of 17 on Friday night.
More light snow and another round of arctic cold air is in the forecast for early next week.
