Also dont forget sea temps have significantly cooled in the last week weeks with the long cold spell.

The faster we can get the primary to die off and eliminate warm advection up here, the better we do. As is, a lot of people especially city and east would have to deal with non-snow precip until the coastal fully forms. West of the city is colder but there's less precip. Verbatim, Long Island and eastern sections could get the most snow even if they rain for the first part.

How much of that liquid is snow for the area?

Kind of hard to tell. This is the text output for NYC from the ECMWF:

thank you don...i know how historic that storm is btw so that isn't lost on me. Just talking about pure amounts. I remember hearing places just to the SW of boston got 3ft plus though in that one though with drifts like 15ft high or something.

You are correct. NWS Taunton has a great .pdf on that blizzard (see p.34 for accumulations):

lets not forget we have a 1038 high to the North. if that low gets down to 976 as depicted. Wow. Thats 62mb pressure gradient over probably 1000miles?

thats about equal to Feb 1978

 

I believe it was 1050 and 986

 

or something to that effect

Check out the bost QPF . EURO 3.5 - not 2.5 , warmest there 850`s get is MINUS 4 , would be insane if that verified would rival 78 , without the wind .

i think they would have pretty insane winds considering the difference in pressure in such a close proximity...i think I saw the GFS showed hurricane force winds on the cape.

As per JB - Weatherbell Analytics 2-5-13 and I quote -

 

I think NYC is on the borderline with this, a 3-6 inch storm that could be as much as foot if we can keep it snow The place that could really get blasted is the island on the back lash. As for the rest of the area I have no beef with the ECMWF widespread 8-16 inches locally 2 feet, though as in many great storms, the rain line may get inland for a while even in southern New England. Put it this way, if you get into the rain, the combination of wind and snow that follows will make it a show.
