The National Weather Service, in an updated advisory issued just before 10 p.m., predicts "accumulating snow for North Georgia" on Saturday, and a winter storm watch for most counties in Northeast Georgia remains in effect from 7 a.m. Saturday through Saturday evening.

Forecasters say snow is expected to develop over west Georgia early Saturday morning, spreading across North Georgia by noon.

The snow may initially be mixed with rain, but will transition to mostly snow by mid- to late Saturday, the weather service says.

Temperatures are expected to be hovering near freezing during the day, and a difference of a few degrees warmer or cooler will greatly impact the potential for snow accumulation.

Forecasters say 1 to 3 inches of snow is possible, with the most significant accumulations centered along a line from Alpharetta to Cleveland.

The watch area is generally along and north of a line from Franklin to Fayetteville to Homer, taking in metro Atlanta as well.

Northeast Georgia counties in the watch area include Hall, Gwinnett, Barrow, Jackson, Banks, White, Lumpkin, Dawson and Forsyth.

A snow advisory is in effect in Habersham and Rabun counties from 6 a.m. Saturday to midnight.

Forecasters also expect 1 to 3 inches of snowfall there, and the advisory says "periods of snow will cause primarily travel difficulties."
