A potent winter storm will move up the east coast Sunday into Sunday night. Potential exists for several inches of snow, especially east of the I-81 corridor.

The National Weather Service says a small system will bring light snow tonight into Saturday, mixed with rain in the valleys. A larger storm system may bring accumulating snow late Sunday through Sunday night but they're still not sure of the path and that will affect storm totals.

We asked Tom Moore, Lead Forecaster/Historian at Weather Concierge if this Winter Storm is considered a Nor'easter:

It could be ... but a toughie... Models have shifted this storm all over the place and they don't even agree with each other... So little confidence because of that ... It could end up being a nor'easter but just a big of a chance of being a "slider" one that passes SE of Upstate NY and "slides" out to sea... Without a -NAO this winter (very unusual) the nor'easter pattern never developed so that makes me circumspect... Basically, I need to see more model runs to see if they "lock" into a solution"... I just posted on FB with this explanation... and will post later when I get more confident... I'm not the only one... chatter with meteorologists in NYS and New England are also have the same thinking as I do at the moment... That's an awful lot of works for an IDK

The National Weather Service says a major winter storm with an active southern jet will move up the east coast on Sunday and Sunday night, bringing the potential for heavy snow west of the storm track. Model differences exist between the CMC, ECMWF, and GFS, but the biggest concern is that the Sunday storm follows too quickly on the heels of the first-weekend storm. It is expected a mass of cold air will drift down from Canada Saturday night, and this heavy, dense air mass may serve to push the Sunday system
further southward.

The best chance for heavy snow will be east of the I-81 corridor, especially over the Poconos and Catskills where several inches of snow could fall. But plenty of uncertainty exists regarding the storm track, and a slight shift in the path will greatly affect storm totals.
