LOL at some of the rhetoric in here...today's event really isn't that far off from a decent early season event over the interior. Yeah, it didn't pan out for most (I'm sure Mitch will get several inches in VT, for example), but lets not pretend that this should have been handled as some complete model guidance mirage from 4 days out....there's a reason we don't lock stuff in from 4 days out, but it doesn't mean dismiss it either because it's anomalous. Remember all the clowns who dismissed the October 2011 storm even 2 days out? Some of them were TV mets too. (but not our own Ryan Hanrahan)
Just to demonstrate the main piece that were different in the snowier scenarios....the streak of energy north of Maine was pressed a bit further southeast on the previous snowier solutions....and that in turn, forced the lakes energy a bit southeast as well as make the overall temperature profile much colder over New England.....
BTW, I agree with Tip that the GFS beat the Euro this time around from about 4-5 days out....neither was correct, but the GFS was closer. The Euro also had a pretty classic burp run that one solution where it was dumping 20 inches on the chickens....that should have always been viewed with skepticism and I think most here did view it that way. But as for a run-of-the-mill advisory type snow, we actually weren't that far off.
