A stalled surface front that continues to bring widespread rain to most of north and central Georgia is expected to shift south as a cold front this afternoon. Behind the front, a cold polar airmass will begin to spread into Georgia. At the surface, a low will strengthen across east Georgia. As this low tracks to the northeast, wrap around moisture will swing into the cold air mass. Rain will mix with and change over to snow across portions of north Georgia this afternoon and evening. The heaviest snowfall will be in the northeast Georgia mountains. Therefore Winter Storm Warnings and Advisories are in effect for much of north Georgia. In addition, as temperatures fall below freezing tonight, any liquid water remaining on the roads will freeze, turning to black ice. These conditions are possible as far south as central Georgia, although the greatest threat of black ice will be across north Georgia.
