More snow is possible in Oak Ridge on Friday night and Saturday, and the forecast calls for heavy snow in areas to the north and east, including northeast Tennessee and western North Carolina, as Winter Storm Jonas turns into a major snowstorm Friday.
A National Weather Service map of expected snowfall amounts shows that four to 12 inches of snow are possible in parts of upper East Tennessee and at higher elevations. Snowfall amounts in and around Asheville, North Carolina, could vary between eight and 24 inches. A blizzard watch has been issued for Washington, D.C., Baltimore, and New York City.
Expected snowfall amounts in Anderson County vary between one and four inches. (Anderson County is the county to the northwest of Knoxville in the map above.)
A winter weather advisory is in effect for Anderson, Knox, Loudon, and Roane counties, among others, from 7 a.m. Friday to 1 a.m. Sunday. It applies to Clinton, Kingston, Knoxville, Lenoir City, Maryville, Oak Ridge, and Sevierville.
The National Weather Service in Morristown said rain will move into the area and change to snow sometime on Friday. During the transition, there could be a wintry mix of rain, sleet, freezing rain, and snow, with primarily snow expected by Friday evening.
There could be a total snowfall of up to three inches by Sunday morning, with locally higher amounts possible, forecasters said.
The Weather Channel said Winter Storm Jonas will cover a large swath of the East Coast as it turns into a major snowstorm. Heavy snow is expected to fall across parts of at least 15 states, with blizzard conditions possible over parts of the Washington, D.C., Baltimore, and New York City metropolitan areas. Winter Storm Jonas will also feature strong, possibly damaging winds, significant icing, and coastal flooding, the television channel said.
The National Weather Service said snow and mixed precipitation could start late tonight (Thursday, January 21) across northeast Tennessee, southwest Virginia, and in the higher elevations and continue into Friday morning.
Snow is expected to begin across the central Tennessee Valley by late Friday afternoon into Friday night and taper off Saturday afternoon/evening.
