Following the arctic air plunging south early January, there will be a chance of snow. Yesterday, the GFS model was saying snow around the 2nd to 3rd of January. Now they are showing snow the 4th through 7th for the Southeast. The storm also looks a lot more stronger. The storms also looks like it is going to last a whole lot longer. One factor we will have to look at it the NAO. If the NAO goes negative, we definitely have a better chance of snow. Even if it doesn't go negative by then, we have another factor, the AO. The AO is currently very positive. It is expected to take a huge drop, a few models even taking it negative. Most models keep it slightly postive, but it will still be a big difference. This will allow for arctic air to plunge south, which it has been having problems doing for weeks now. This might as well also be the coldest air of the season so far. There will be days that temperatures don't make it out of the 40's. There might even be some nights with temperatures in the teens. Anyway, don't be suprized if the forecast does change, because this is quite a while away. Weather models this far out usually change quickly, so don't be suprized if that does happen. I am actually more comfident then usual with this storm, since we will have all the cold air in place. So, cross your fingers and everything else, and maybe it will snow.
