Weekend Clipper Snow Idea

I figure at this point, despite how awful the computer models have been lately, I can offer an idea for the snowfall from the weekend clipper. It comes Saturday and Sunday, so of course there can still be large errors 3-4 days out, but why not take a stab. The big coastal storm idea of course is still gone, but this may develop strong enough to give parts of northern New England a good snowfall. This idea is shifted a little north of where I had the original lines drawn (not really "drawn", as I didn't have a map of course, but where I stated they would be). I'm highlight only the areas I feel have the best shot at 2 or more inches here from the clipper itself, not from lake enhancement or upslope snows in the mountains in the cold air behind the storm (to be sure that will accumulate too, but I consider that a separate, post clipper event). So keep that in mind when looking at the following map. You will notice I have a break in the 2+" snow potential in New York state, where I think there may be a "dwindling" as energy gets transferred to the coast and away from the primary low / batch of precipitation.
I will adjust if anything notable changes in the next day or so, and maybe tomorrow we can get into what lies ahead next week (European model making some "rumblings" again, but that has been an awful model lately). As always, click to enlarge and view my astounding map-making skills! Ha!
