The highest bust potential based on history imo is not whether or not any falls but how much (if any) accumulates due to it not being cold enough in marginal situations when precip isn't heavy like this one appears to be. Models often overdo accumulations more than the opposite...at least in ATL area. Just as a betting man as opposed to going with my feelings, I'd take the under on average model accumulations and hope for a rare bust the other way.
Example: remember last winter's bust near Macon?
But any just falling (2nd day in a row) would be a victory imo. I'd keep the accumulations expectations low in and near the city, itself, while still hoping for a surprise.
Sometimes, although rare, things can bust the other way just like in December of 2017. We went from a forecast inch or two right on up to a foot.
