It looks like we're going to be in for at least three periods of unsettled weather with at least two of those bringing the possibility of some snow to the north Georgia mountains.
A cold front enters the state on Friday and the NWS has this to say about it:
"This timing opens the window for the possibility of a wintry wake-up in the north Georgia mountains on Saturday morning. 00Z Saturday model soundings show dry air near the surface in north Georgia that would be ripe for evaporational cooling. By 06Z the model soundings clearly demonstrate evaporational cooling close to the surface that helps create a below-freezing column which is necessary for snow. The model soundings for metro Atlanta and points south show a warmer column which would keep any precipitation liquid."
P-Type Nomogram Charts can be found here. If you look at Atlanta http://www.daculaweather.com/nomogram_ffc.php the NAM is showing thickness levels ripe for snow for the 12th. Scroll down on the page to and mouse over the example chart to see how it works.

So the other chance is again on Monday night and into Tuesday where north Georgia might get another opportunity at snow while it's beginning to look like a potential severe weather event around Thursday. We have undergone a pattern change but it appears the cold might be brief. While the models are playing catch up in trying to figure out what's going to happen, the timing of these systems will be off and only when we get to within a 2-3 day time span will they start to get a grip on the situation. There is lot of activity coming up, with lots of possibilites of different scenerios so stay tuned for more information as we get it.
