Dude you need to give it a rest. Look at the snowfall maps. There could also be a warm layer in there somewhere that you wouldn't see without looking at the soundings.

If your basing your thinking solely on the snowmaps u will fall flat on your face... have to look at the overall picture here.  Anybody north of say Upper Manhattan/Bronx area will see 3+... once north of 287 in Westchester the amounts will probably double.

I will never take you seriously again / no one should.

THESE ARE THE LEVELS /YOU DON`T USE SOME ALGO PRECIP GRID TO MAKE A FORECAST 

Hour 48 

.3

850 -4

925 - 2

BL 32

DP 31

what layer is warm there WHAT LAYER ? 

Dude , no one should ever view you an even a passable analyst in here after that. 

 

 

I was trying to dumb it down for ya.

Enjoy your snow or rain or whatever.

Anyone that knows me knows that I think snowfall maps are a joke.

 I really don't think you need to dumb it down for PB I am pretty sure he is more than sufficient in analyzing what the models show and don't show as of yet.... have fun making those forecasts based solely on snow maps because you will probably be wrong 9 out of 10 times.

You were given the actual soundings and instead of forecasting for it , you told everyone to look at the snowfall maps and now you don`t use snowfall maps.

 

Then after seeing the soundings you post " there`s a warm layer somewhere "  I asked you to find me the warm layer 700 ? 850 ? 925 ? BL ? 

 

Come on Mr, I don`t use snowfall maps , find us the warm layer as to why on a NE wind the soundings I gave you at hour 48 at KNYC is not snow.

Ya I've been on this board back to the days of eastern ..... and i remember you having stated that before ..... then why are you referring to the snowfall maps in response to PB post.

I go back to the Eastern days as well.

PB takes every marginal event and makes a case as to why the models are wrong and a snowier outcome is the correct one.

I conduct my own analysis and when necessary post why I am skeptical.

I have posted my reasoning as to why I think the South facing shore of the five boroughs as well as much of Long Island and coastal NJ is in trouble with this event. I wouldn't even be surprised if I mixed up here. If people want to disagree that's fine by me.

This genuinely confuses me Yanks.  I've been on the boards with you since the days of the Bill Evans forum and have always thought you were a respectable poster, but why should anyone look at "a joke" when trying to nail this down?

Bottom line: N&W crowd is in for a nice event in the midst of a "thaw."  We coasties are riding the line, but potentially might be in for a nice surprise.  West trends late in the game during past storms this season gives me some hope here on LI, as does Paul's analysis.

NJwx85 is the king of saying “I don’t use snowfall maps” and then basing his analysis off of snowfall maps.  

Like anything else, they can be useful at times. In this case, models are picking up on something which is causing less snowfall Southeast of the city. That something is an initially warm surface. If you want to ignore it, do so at your own risk.

Snowfall maps are a joke. They aren't to be taken literal. However when every single model is showing basically the same thing, it's a sign.

I looked at the weather.us outputs, and 925 temps look toasty for most of the good precip from the city on east this run. If it’s near zero that’s fine, but the Euro has it at 2-4C. That’s enough to melt the snow before it makes it to the ground. The 925 low goes right over my head and then into SE CT, and for much of the time those winds come from the south or east. That tells me all I need to know. The 2/13/14 storm will be the last time I ever underestimate warmth in that layer.

It’s really strange to me.  In most of the numerical guidance the T/Td spread is good enough that except maybe central to eastern LI should be snow.  The wind is simply too light and it’s ESE but only for a short time and mostly before precip falls.  I’m not sure how it would be warm enough for rain anywhere in the Metro or most of Nassau if the rates were even borderline decent.  You usually need really deep strong South or east flow which is missing

Agreed, I would be shocked for anyone NW of NYC (especially GSP) to see any appreciable rain/mix

At hour 48 - 925s are -1  in L/B and the BL is 33 with .3 falling.

 

I think once east of Nassau County that time frame they are have an issue.
