Winter Weather in Washington, Tennessee

Light snow with likely wintry mix based off neighboring reports fell across Washington County, with a trained spotter reporting 3 inches of snow in Avondale. Additionally, 2 inches of snow near Milligan College was measured, 2 inches in Limestone, and 2 inches in Johnson City.

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.
