Severe Weather Team 2 Meteorologist Karen Minton has been tracking winter weather in metro Atlanta for more than 30 years. She said the band of rain and snow mix will begin entering the north Georgia mountains early Tuesday morning and then move into metro Atlanta in the afternoon.
This will continue to shift southeast over north Georgia through the morning hours.
The system will be drying up as it moves south, but there is still the threat for some accumulating snow north of I-20.
By the afternoon commute, the snow and rain mix will move out of Georgia, but the cold will stick around.
TUESDAY NIGHT
Behind the snow mix will come a dramatic drop in temperatures.
Winds will rapidly increase behind the cold front and will persist into Tuesday night. Wet and slushy spots will freeze Tuesday night and into Wednesday morning.
