Yeah this isn't a good setup for us upstaters, or SC peeps in general. Here's my nonthechnical take. The low isn't where we need it. We need a low tracking much further South along the gulf coast or just inland, then slightly inland and up the seaboard. In the setups like this one the mountains to our North, NW, AND West all block the cold air and dry out the moisture, which is a bad combo for snow. Northern AL, GA, Atl and even panhandle of FL can get it in these setups b/c the wraparound moisture can moe into the cold without having to travel over or through the mountains (it can go around the mountains instead) so they're not subject to downslopping, which drys and warms the air. The western upstate is especially vulnerable to this, and by the time the cold air makes it to us, the moisture has either been dried out or is gone completely. We need a better placed low and the cold needs to already be in place for us. Unfortunately, either of those rarely seem to happen any more, and both together has become almost unobtainable.
We can use the 3k Nam in this range
