Very possible however my red flag for this event, is zero ensembles support, the EPS and Gefs are pretty unanimous on a near miss solution, which is right in line with ggem/GFS/nam/euro.... no reason other than staying hopeful to think this thing has what it takes to get out ahead of the energy dropping from Canada allowing for the trough to dig and phase in time to bring it up coast...I'm not sayin it's impossible, I just think it's not gonna happen for anyone west of eastern Long Island... best place to be is ELI, and I think they could overperform, but I think they overperform with wave 1 not wave 2...

 

Also keep in mind single digit dew points, and a very cold air mass, with a progressive flow, and late phase... your gonna need to see some decent DBZ overhead otherwise your LE pours virga 

 

only shot we have is models are wrong on the timing and we get an earlier phase

The big question, is this the start of a continuing trend further north and west? The next 24-36 hours of model runs should be very interesting.

This sums it up perfectly from ORH Wxman in NE thread:

Here's where the PNA ridge comes into to play...a more amped PNA ridge will help push the lakes energy more south rather than east so that the southern stream has room to round the base and come up the east side of the trough....so we'll want to root for a more amped PNA ridge. A sharper southern stream can help too.

The ECMWF actually had a nice improvement vs. the 1/5 0z run.

ACY: 0.22" (0z: 0.02")

ISP: 0.14" (0z: None)

NYC: 0.03" (0z: None)

SBY: 0.42" (0z: 0.18")

 

This is going to be close. I think the radar will be painful to watch as it's dumping on the fish.   Someone's going to smoke cirrus north off the city too ala feb 5 2010. The jersey shore and the island are very much still in the game for a moderate snow event (2-4, 3-5")

I agree. Hopefully, the Jersey Shore and Long Island will cash in, even if the rest of the area doesn't. Cape Cod might do well, too.

Feeling good about a decent event from the Queens border on east. Nassau and Suffolk look good for 1-3/2-4, with Eastern Suffolk up to 6+? Will be nice to have a snowfall on a Sunday, take my daughter out sleigh riding and what not, especially on top of tomorrow's snowfall.

That's probably the reason the models have shifted the track somewhat closer to shore. Hopefully, the PNA will pop positive to further sharpen the trough.

So allow me to bother you with this question Don, what could increase the chances for a temporary + PNA?

Right now, greater amplification of the pattern than currently modeled would probably lead to that outcome. The last two days have seen the guidance increase the magnitude of the forecast transitory rise in the PNA.

Appreciate the clarification Don! Always a genteleman.
