Heavy Snow — Roane, Tennessee

2025-01-10 · Roane, Tennessee

Event narrative

Heavy snow fell in Roane County, primarily across the southern half of the county, with lesser snowfall amounts in northern Roane. Still, a CoCoRaHS observer in Kingston reported 4 inches of snow, a public report in Kingston reported 3.5 inches, but the CO-OP observer noted only 2.5 inches of snow along with light sleet.

Wider weather episode

Low pressure cyclone passing to the south with upper level forcing induced a broad and significant snowstorm across the region, including East Tennessee, which experienced heavy snowfall. A frontogenesis band across southern Tennessee and northern Georgia helped power higher snowfall rates early into the event across southeastern Tennessee, resulting in locally heavier snowfall before warm air advection brought a changeover in precipitation type to icing and eventually to rain.
