The episode as NWS FFC wrote it up.
A deep, broad upper trough covered much of the U.S. at this time. The center of the upper trough across the northeast was supressed unusually far south. A cold air mass prevailed across much of the eastern two-thirds of the U.S. with below normal temperatures. A short wave was rotating through the upper trough and provided enough support for a light snow event across northwest Georgia during the morning of December 5th. The maximum snowfall reported was 1.5 inches from Dade county in far northwest Georgia. Trace amounts of snow were reported as far southeast as Cherokee county, a northern suburb county of Atlanta.
