Euro definitely just came in colder. Gets 2 inches of snow down close to NYC and into north-central NJ now. Would be nice to see a late colder trend today into tonight.

The Euro has been by far the coldest the last 2-3 runs.  It also generates much more precipitation in that 12-15Z window across New Jersey while many others have spotty  precipitation or nothing

The NAM is in its good range, so hard to discount its solution of almost nothing, but RGEM and EURO are robust.   GFS in between.

A good forecast would be 1-3 with highest amounts N and W of the city....

The NAM has wanted nothing to do with it for days now. There are definitely going to be p-type issues looking at the soundings, the usual mid-level warm nose will be there and some areas will see boundary layer issues as well. Nothing really has changed since yesterday, still 1-2/1-3 inches of snow

[HailMan06]

What's the starting time for our subforum?

[SnowGoose69]

the 3km NAM was a bit more organized  this run but it’s still quite a bit slower than all other models with nothing into the metro til 17z.   All others are more or less 14z with some as early as 13

[Rtd208]

Winter Weather Advisory in effect here from 1am until 1pm Tuesday for up to 1" of snow and ice accumulations up to 1 tenth of an inch.

Yep and the ratios aren’t going to be that good with mixing issues, the actual snow amounts are going to be less. Some of those totals on that map are sleet counted as snow

Inverted trough ?

Maybe for New England

Hi!.  The following is a start for the advisory.  I think it will eventually need expansion to all of LI.  At 6P, I'll add the new regional snowfall forecast. mPing and icy and or/snow covered pavements here we come for a manageable minor advisory event, that still has 1+" snow possibilities for LI, especially if we get the backwash (sewd moving) after 7AM Wednesday, associated with the developing low s of LI.  Think we may see some surprises on qpf over 1/4" on LI.  TBD.

Hot off the presses....From the National Weather Service: (And this is for Rockland), only up to 2 inches of snow total from this, for NYC, even less, up to 1 inch total. This is a very, very minor snow event. Please stop trying to turn this into something it’s not. Rockland: https://forecast.weather.gov/showsigwx.php?warnzone=NYZ069&warncounty=NYC087&firewxzone=NYZ069&local_place1=Montebello NY&product1=Winter+Weather+Advisory&lat=41.1288&lon=-74.1181#.YA8y8aQ8IlQ Here’s NYC, 1 inch total: https://forecast.weather.gov/showsigwx.php?warnzone=NYZ073&warncounty=NYC005&firewxzone=NYZ073&local_place1=Bronx NY&product1=Winter+Weather+Advisory&lat=40.8489&lon=-73.8762#.YA8z_aQ8IlQ

Thanks... I think NYC is in it now. Impressive collection of EPS lows s of LI 00z/Wed.  Nice inflow potential. 

[NJwx85]

Expecting 2-4" here which could end up as my largest snowfall since the pre Christmas storm.

Minor for snow, and an advisory would possibly not have been issued for ONLY the snow amounts posted, but we're dealing with frozen ground, snow and maybe sleet/freezing rain mix, and maybe e just a little more qpf than what is modeled if the inverted trough proves real.  Also, this is a at least a climo advisory event. Might need to deice aircraft.  I don't think is melt on contact unless treated surface. Jury may be out on final snow.    I'll post the CoCoRAHS finals either Wed or Thu. Probably 32F or below through the entire event nw of I95 and maybe even NYC/LI.  NAM BL temps 2C at midnight tomorrow night might be okay at the top of the BL but if the wind is turning north...then I suspect colder CT airmass seeps down across the sound.  So yes, minor- however, hazardous untreated.  

[sussexcountyobs]

My WWA for Sussex county calling for up to 1" of snow and sleet. Then .1-.2 of freezing rain. Folks in and around the city shouldn't get their hopes up for more than that.

[HeadInTheClouds]

WWA in MHV. Expecting 2-4. 

[HVSnowLover]

Gfs has a nice burst tomorrow early afternoon. We’ll see.

RGEM as well-still impressive north of the city with 3-5 inches-sharp cutoff right around I-80

Rates are actually pretty good tomorrow afternoon on the RGEM, might help the city stay snow longer with the initial batch if it's really that heavy (big if)

I don't understand why all these maps are showing my area 3-4" while my NWS forecast is saying only up to 1" of snow/sleet?

[BxEngine]

If you dont want to discuss minor storms, im sure there are other things you can find to pass the time, let the people who want to discuss the weather continue to discuss the weather. Thanks.

Because sleet is treated as snow acc at 10 to 1 and it's usually much less, maybe 2.5 or 3 to 1?  Bottom line, inflated.  Best to start with positive snow depth change and think it out form there. Or if you have the model data... monitor the EC etc snow depth change and use that as a bottom #. 

[sussexcountyobs]

Thanks Walt. No. I do not have any model data except what you guys post here. I rely on you guys for that. So. Most likely the NWS forecast is what to be expected. Hopefully they bust low.
