My guess right now would be 1-2" in the city, less than 1" west and north, 2-4" for Nassau and western half of Suffolk and 4-7" eastern half of Suffolk (east of William Floyd Pkwy). 1-2" down I-95 in NJ, 2-4" east of there and 4" or more starting in coastal southern Monmouth and Ocean Counties. I'd really have to see another bump west to go higher than that. 

I think this is an excellent forecast. 

I am telling my friends in western suffolk to expect about 3", which would be terrific.

Sounds pretty good... Those 5-7" amounts if they happen at all will prob be from Riverhead eastward

Not anymore but many people thought that was possible

Pattern recognition buddy.

We all get sucked in by nice looking model runs, but the key is knowing when it's likely to correct back since the pattern either supports the solution or it doesn't.

This is a huge hit for SE Mass. This is the reason why Boston averages significantly more snow than New York. Longitude + latitude = snow

It's part longitude there for this storm and part ocean effect for the Cape. The storm has slightly more time to develop for them as well. And just in general, progressive La Niña patterns are better for New England than for south of them.

Ukie is 0.30 LE from NYC east. Verbatim an advisory snowfall for the city proper. 

If the Euro  follows suit, i think WWA may be in order for NYC to the suffolk border, and WSW on east from there. 

RGEM supports the UKIE btw, and the NAM.

Just curious if this is your call for the second system or you're just describing what the NAM output is.  And if it's your call, how much of the call are you basing on the NAM vs. other observations and/or model output to date?

I like 6 from both waves at KNYC.

Out on Orient point.  This is .75 to an inch for him and I working off the premise of 15 to 1 .

- 15 at 850 with deepening LP .The VVs look good and that lift and those mid levels support 15 to 1 

 

I like the NAM and the RGEM here .

I have ignored the GFS its just chasing convection off OBX 

 

Same error for 2 decades

 

For those wondering what PB meant, I asked last night and he was talking 6-12" for NYC to Eastern LI from both storms, combined.  Given that NYC only got 1" or so from storm 1, this prediction will likely be wrong.  He didn't mean 6-12" from the 2nd system, though.

UKMET looks like a solid 4in+ for all of Long Island. NYC looks good for 2-3in here. 

UKIE ticked up totals a bit city east, and decreased them a bit city west, but just model noise at this point. 

There will be one heck of a gradient with this puppy.
