An unusual winter storm swept through the Deep South on Tuesday, bringing significant and even once-in-a-lifetime snowfall to unexpected areas.

The winter storm brought up to about 2 inches of snow over parts of north Georgia and areas south of Interstate 20. “There was a sharp cut off in accumulating snow basically right along and near I-85 with not much, as expected, over areas north and west of Atlanta,” Meteorologist Brian Monahan said.

A winter storm watch has been issued for parts of metro Atlanta for Tuesday morning through Wednesday morning.
