That's a historic depiction on the GFS, kind of speechless looking at that tbh.

Getting some January 1996 vibes with these late north bumps.

Looks like the phase happens in a good spot and the 500mb low consolidates so we have a good enough mid level setup to generate lots of precip for most of us. 

one consolidated low it wobbles a little but it drops a lot QPF SO WHO CARES! wow

[JonClaw]

If I could I'd take this GFS, run with it, protect it, nurture it...

Here's hoping the Euro agrees.

Tip of the cap to Forky - called for a possible pattern ending/breaking Archambeault Event with KU potential.

GFS OMG

Chefs kiss on that one

This run occludes about 6 hours later so the deformation banding is able to get further North and West. So just about everyone here would be looking at 12-18" with locally up to 30" possible under the heaviest banding, most likely Suffolk County.

GFS coup is like watching a dog win an olympic gold medal

[nycsnow]

Gfs is 40-60mph winds for the coast for hours 

[NJwx85]

Since it will be asked, looks like start time would be Sunday early afternoon, from Southwest to Northeast. Heaviest snow would be Sunday evening/night with most of it over by this time on Monday with some residual bands possible as the storm starts to rot just East of the benchmark.

I don't care what the clown maps show, 2-4" per hour under this banding.

 

Agreed the surface depiction doesn't capture this as well. Amounts would be higher 

[NJwx85]

Okay, I'm officially excited. Almost 2" liquid into NYC and 1"+ back into PA and Upstate NY.

[nycsnow]

CMC looks better

It's much closer than you think to something larger.  But as of right now I wouldn't forecast anything more than what you said. 

After the 12z suite it will probably be ok to bump totals.

If the GFS is correct, it will be puking snow for about an 8-12hr period on Sunday night.

The AIGFS continued a multi-run improving trend and the GFS was another excellent run... but it was actually slightly east of 6z with mid-level and surface lows. Reading the descriptions before checking the model, I expected an improvement. I think unfortunately people mostly just look at the QPF for their backyard when interpreting a model run. Anyway, a minor wobble in an OP run is just noise. The consistency of the GFS, especially considering other model trends, is very encouraging.

Will be looking at GEFS to see if they stay the same or improve
