KNOXVILLE, Tennessee (WATE) – Most of eastern Tennessee will spend lunch watching the snow fall according to the latest models from the National Weather Service.
The NWS expanded its winter storm warning Wednesday night to include three more counties on the Cumberland Plateau. Morgan, Fentress and Cumberland counties were added to the warning until 10 p.m. EST.
WATE 6 On Your Side meteorologist Victoria Cavaliere said on Wednesday evening that temperatures would start in their mid to upper 20s with a few breaks in the sun before winter weather sets in.
The plateau will see snow first between 9 a.m. and 11 a.m., with about 2-4 inches of snow expected.
“Some recent model races have slowed this system down a bit, so it might be closer to 10-11 am for the field to start seeing this snow,” Cavaliere said.
The Southeastern Tennessee Valley will experience a wintry mix of freezing rain and sleet starting around 11 a.m. before turning to snow until around 1 p.m. The north valley will see more snow than a winter mix.
“If we see a period of freezing rain and sleet for an extended period before the snow arrives, that will reduce some of our snow totals,” Cavaliere said.
The valley should receive 1 to 3 inches of snow. Pockets of concentrated snow called snow bands could locally bring larger quantities.
“Depending on where these are settling, certain areas – even within the same county – can potentially see locally higher totals,” Cavaliere said.
Mountains further east, including Greene County, higher elevations in Sevier County, and the Tri-Cities will see snow around noon to 2 p.m.
Snow should first accumulate on the grassy surfaces, then between 2 p.m. and 4 p.m. the temperatures on the road will be low enough that the snow can begin to stick to the roads.
