From the National Weather Service this morning: 

… LIGHT WINTRY MIX OF PRECIPITATION POSSIBLE TONIGHT AND TUESDAY NIGHT ACROSS PORTIONS OF NORTH GEORGIA…

AN APPROACHING STORM SYSTEM WILL BEGIN SPREADING LIGHT RAIN INTO NORTH GEORGIA TONIGHT. AS THE PRECIPITATION BEGINS IN THE NORTHWEST THIS EVENING LIGHT SLEET MAY MIX WITH THE RAIN. THIS PRECIPITATION WILL SPREAD EAST OVER NORTH GEORGIA OVERNIGHT. MOST AREAS ARE EXPECTED TO REMAIN ABOVE FREEZING WITH LITTLE OR NO ACCUMULATION OF SLEET ANTICIPATED. HOWEVER… HIGHER ELEVATIONS OF THE NORTH GEORGIA MOUNTAINS MAY SEE A LIGHT ACCUMULATION OF ICE AS TEMPERATURES APPROACH FREEZING. THE PRECIPITATION IS EXPECTED TO CHANGE OVER TO ALL RAIN BY EARLY TUESDAY MORNING.

AS THE STORM SYSTEM SWEEPS EAST OF REGION LATE TUESDAY… VERY COLD AIR WILL SPILL INTO THE REGION. THERE IS A CHANCE FOR A FEW SNOW SHOWERS OR FLURRIES OVER PORTIONS OF NORTHEAST AND FAR NORTH GEORGIA TUESDAY NIGHT. NO SIGNIFICANT ACCUMULATIONS OF SNOW ARE EXPECTED AS THE STORM EXITS… BUT SOME AREAS MAY SEE A LIGHT DUSTING. THE MAIN THREAT WILL BE THE FORMATION OF BLACK ICE ON NORTH GEORGIA ROADS LATE TUESDAY NIGHT AND EARLY WEDNESDAY AS WET ROADS FROM TUESDAYS RAIN ENCOUNTER TEMPERATURES FALLING INTO THE MID TO UPPER 20S.
