Thats 18z GFS on wed, more than 48hrs ago and 9 runs ago

 

Yep...I thought today was the 29th but yesterday was...so it only gives my original point more validity.

This run hammers NYC with snow. Close call but still did it. Over 1.50 QPF for NYC. Jeez.

Ant, NYC is big....and SI is part of NYC. It could stay snow in the Bronx and mix in SI and Brooklyn, no?

GGEM is almost all snow at KNYC the 0 line gets stuck just S of the Driscoll bridge.

Too close. You can see the Driscoll from Raritan Bay just off SI. I believe LCosgrove mentioned Perth Amboy as the line, just north of the bridge. My experience is that if it gets that far, it goes further and the city gets it too. Anecdotal I know, but anecdotal is still worth something.

All the models got the same data tonight...there's less uncertainty and ambiguity because the heavily unmonitored ocean does not play that much of a role...so a bunch of similar solutions with the rain / snow line near 40.5 N would not be unexpected.

This type of situation, the mid latitude cyclone will not cut north...or likely even trend any further north...if you can deem today's de minimis shift a "trend".  I've elucidated as to why in several previous posts; but JM's exuberance about the so called "north trend" does need to be countered just a bit...

Again, hopefully I'm wrong and this is the SWFE to counter the general trend WRT these.

So tomorrow, this may be a burlington vt storm

 

You talk about hyperbole.  I don't have the energy to save and upload the images from 12z and compare them to here at 0z...but saying there has been some quantum leap north is quite simply untrue...it has edged north...but well within the range one would expect within 2 runs of a model...so lets not make the adjustment into something it is not.

Possible. This storm is going to have a tight gradient.

The mechanism to drive the heavy precip is the tight thermal gradient, so I agree that conditions might change over a short distance. Pay more attention to the 850mb low track than the surface low track-if the 850 low goes over or north of you, it won't stay snow, regardless of the surface cold air and low.
