Update on Winter Weather Advisory for Loganville and Grayson

Snow is expected across north Georgia this afternoon and tonight, according to the National Weather Service's Winter Weather Advisory for Loganville - Walton County and Gwinnett County, including Grayson and Gwinnett County portions of Loganville.

A "cold polar air mass" is expected to spread into north Georgia as widespread rain shifts south. The result: Rain will mix with and change over to snow across portions of north Georgia.

The heaviest snowfall would be in the northeast Georgia Mountains.

The winter weather advisory that is in force includes Gwinnett, but not Walton County, at this point. It lapses at 7 a.m. Friday morning and warns of light snow and black ice north of a Carrollton-to-Atlanta-to-Jefferson line and south of a Rome-to-Hiawassee line.

Very little, if any, of the white stuff could accumulate on grassy and elevated surface and could create nuisance-driving conditions. Black ice also may form Thursday night and Friday morning when temps dip below freezing.While winds will continue to gust up to 30 mph, temps across north Georgia are expected to drop to the lower 30s by midnight.

Little to no accumulation of snow is expected in the local area, which would see the white stuff mainly between 9 p.m. and 11 p.m., according to the NWS forecast. The low should dip to 27.

A winter weather advisory for snow means that periods of snow may cause primary travel difficulties. Use caution while driving, NWS says.
