When comparing Mount Washington totals to Jay, it is interesting to note that there are alot of Cold Nor'Easters when Mount Washington is ABOVE the heaviest snowfall.
I remember in Dec 2003 skiing in nearly 60 inches of fresh powder at mid mountain on Wildcat (no exageration) and MWO only recorded 11 for the storm. Earlier this year, one of the October storms, MWO did worst than wildcat and Hermit Lake.
Nor'easters have suprisingly low clouds for such dumpers, and often times Jay and other high peaks will get it while the highest will not. Therefore I can see how Jay could have higher totals than MWO.
