Meteorologists say widespread rain should switch over to the white stuff sometime this afternoon or evening, but the heaviest snowfall would be in the north Georgia mountains.
The winter storm watch—in effect for Cobb and other counties from this afternoon through Friday morning—means there is a potential for significant snow, sleet or ice accumulations that may impact travel.
Locations north of a line from Carrollton to Atlanta to Jefferson could see an inch or less of snow, while accumulations in the northeast and northwest Georgia mountains could reach 2 to 4 inches.
Possible black ice is a hazard across the area on tonight and Friday morning when temps fall below freezing.
Snowfall should begin in northwest Georgia by mid-afternoon, then continue through the rest of north Georgia through the late afternoon and early evening hours.
Light accumulations up to 1 inch are possible on roadways across higher elevations in the mountains.
In Cobb, expect occasional rain before 5 p.m. today, then rain, snow and high winds, according to the NWS forecast. New snow accumulations of less than half an inch are possible Thursday and Thursday evening. The temps are expected to drop to about 29 degrees Thursday night and come back up to a high of 48 or so on Friday.
