Heavy Snow — Unicoi, Tennessee

2025-01-10 to 2025-01-11 · Unicoi, Tennessee

Event narrative

Heavy snow fell in Unicoi County, with 5.8 inches of snow measured east of Rocky Fork, and 3.5 inches of snow measured in Erwin.

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.
