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.
