The National Weather Service has issued a winter storm watch for a large portion of N Georgia for tomorrow afternoon. I am still working on all the new model data but I will post what I had said earlier today regarding the snow totals for the entire N Georgia area and I will have a full new model analysis at 4:15 pm today.
Where and when I am Looking At
The graphic is below to illustrate where I think the winter weather will be. First of all this system will start out late Wednesday night as a heavy rain producer that will last through the day on Thursday. Then as the upper level winds start to change and the cold air at the mid and upper levels starts to move in, that is when we will start to see the change over to a winter mix. This should start to happen around 1-3pm on Thursday. As far as locations, here is what I am thinking:
Metro Counties: A winter mix with no accumulations
North Metro Counties: (Bartow, Floyd, Godron, Pickens, Dawson, Fannin, Gilmer) Could see a dusting to a bit more on the grassy surfaces, no travel problems.
North Georgia Mountains: I think there is a good chance that by the time this system is done and gone the mountains could see around 1-2 inches!!
I really don't think I will be changing this forecast much, but this is a very dynamic system and as it starts to get closer to the area I will have a much better idea what it will be doing. Right now I am giving this a 4 on a scale of 1-10 for snow accumulating up north.
