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

Event narrative

Snow fell in a couple of bursts over Knox County, with wintry mix falling between roughly 1630 EST and 1900 EST based off reports from a trained spotter and the official airport station just south of Knox County. A light glaze of freezing rain was reported by a trained spotter during this event, less than .05. As far as snowfall, 3 to 4 inches of snow was observed in Karns, Farragut, Halls, Powell, Bearden, Maloneyville, and Forest Lake. A NWS employee reported a final total of 2.4 inches near Paulette.

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.
