Meh. Not a good look for most.  I still might get a few sloppy inches but the trends are what they are.   I will still be watching over the next two days to see if there are changes 

Models still have you in the game

Anyone in and elevated N of Pike is still in the game and those near Portland Over to Dendy need to watch as well 

The 6z gfs clown still hits The 3 big erly uplsope nor’easter areas from S NY to Berks , N orh county to Monands and just N of MHT really well

You were never in the game, and even here for that matter. Those wobbles happen several days out. Maybe it wobbles back south for higher interior. Who knows. 

Yeah even when it was tracking over MVY he was still getting a rainstorm. Lol.

Yeah... we were never really in the game down here, but I didn’t think anybody else in SNE was either, save for maybe the highest elevations out west, and that seems to be playing out as well.

Too much garbage to sort through to get a decent system. Trying to thread a needle that just doesn’t want to happen this year

Albany AFD:

.LONG TERM /SATURDAY THROUGH TUESDAY/...
All models continue the idea of a storm system impacting the region
Saturday/Sunday. Although the 00Z model suite has brought little
clarity to the situation.

The precipitation onset time has come into better agreement with
the GFS/ECMWF bringing precipitation into the area Saturday
morning into afternoon.

The GFS continues to be consistent in its evolution of surface and
upper air features bringing the closed low across New York City with
the surface low tracking toward Cape Cod. On the other hand, the
ECMWF now depicts a more westward and northward solution bring the
closed upper level low and its surface feature near or slightly to
the west of the CWA.

A check of the GEFS ensembles shows that the likelihood of heaviest
precipitation (24 hour 1 inch probabilities) would occur across the
mid-Hudson Valley northeast into Litchfield and Berkshire Counties.
24 hour 0.5 inch probabilities exceed 50% across the entire region.
GEF probability of 2m temps < 273K at 18Z Saturday are zero for
Albany and points south. Therein lies the challenge -- What
will surface temperatures be during the event?

The forecast grids were populated using a GFS top down scenario.
Along with the surface temperature forecast, this process yielded a
big question mark for valley locations - Rain/Snow/Rain and Snow?
The current forecast yields little in the way of Valley snow. Valley
temperatures are forecast a few degrees above freezing, so it`s
close. In the higher elevations of the Catskills, Helderbergs,
Berkshires, southern Green mountains the more likely p-type is
snow.

An ECMWF track would bring in more warm air aloft and offer the
possibility of a storm featuring mixed wintry precipitation -- sleet
and freezing rain. In constructing the forecast this ECMWF scenario
was not considered. That`s not to say it couldn`t happen.

In summary, although we are getting closer to the event, there is
still considerable uncertainty in how this storm plays out. We
continue to assess.

The times have changed when the Euro gets tossed.
