Exactly, it will become much more difficult for it to snow here. Virginia is what NC used to be like, chances wise. NC is like what SC used to be like. Keep shifting things a state down for each state. Warmer and warmer here.
GFS has the right idea with the cold rain. Until I see it show a snowstorm within current range (< 200 hours) for more than 1 run, it is safe to assume it is right with this look. Snow really seems to be getting more difficult to produce south of DC now days and even they struggle.
Just wait until the next run, it will be 40 degree rain. GFS has been the only model showing winter storms this winter, for the most part. Just needs a few runs to adjust to reality for that range.
