Welcome to another wet and gray day. The only question is if there will be any white later on.

WSB meteorologist Kirk Mellish has been watching this complex weather system called an upper level low all week. He says it will arrive Thursday afternoon and then we could see our first snow fall of the year. If only a little bit.

“The rain to snow changeover could give a temporarily coating are car tops and bushes,”  Mellish says. “But it will be wet pavement for most of Atlanta. For most of us it will be curiosity or novelty snow with rain mixed in.”

But these types of systems are hard to predict and that significant snow line could shift south.

Right now the forecast calls for 2-5 inches of snow in the north Georgia mountains.  The highest odds of accumulation are along and north of a line from Carrollton to Toccoa. The rain-to-snow changeover is expected between 2 p.m. and 8 p.m.

The National Weather Service says a winter storm watch will go into effect Thursday afternoon for everybody north of a line from Carrollton to Athens. That includes the metro counties of Cherokee, Cobb, DeKalb, Douglas, Forsyth, Fulton and Gwinnett.

The morning temperatures will be the warmest, Mellish says. We will be falling from the 45-50 degree marks in the morning.  The wind and cold temperatures move in after dark, with lows around 28 to 30 degrees.

Black ice could become an issue on bridges and overpasses, especially in the mountains. But spots are expected to be scattered.

Once this system move through, we finally get to see some sunlight for the weekend.

Friday, Mellish is calling for partly to mostly sunny skies with highs in the low 50s and lows 28-33.

Things will be a little warmer for Saturday with more sunshine and highs around 56 and lows 30-38.

The sun remains for Sunday and Monday, but high temperatures will hang around 50 degrees with lows dipping into the 20s.
