This is what you're going to get unless you have a stronger coastal. The weak primary goes to Pitt and the sorry excuse for a secondary develops too far north. It looks so much like a dumbed down version of PDII. The primary low closed off in that storm which amplified the whole pattern. We're missing that here.

WOW the GFS is clearly missing something here.  

Maybe not. We really don't have a lot of wiggle room here for a very wintry solution that close to the city (north and west is an exception, for ice). The SE ridge is in place and will keep the warm air close by, winds look like they switch to E or ESE unless the coastal really takes over, unless it's a very weak system that doesn't deliver much warm air and therefore little precip. If I had to guess at a place that does well, it's along I-90 from Boston to upstate New York under the deeper cold air.

That's it. The setup at H5 is a disaster. You get a weak coastal that skates by. The 12z GFS yesterday had a much more potent coastal and it's been trending weaker every run since.

It's trending towards the Euro. I think this will be a few inches just like this last storm. The pattern isn't ripe for a monster.

 

Only .3-.4" of liquid falls in frozen form so a couple inches of snow and then sleet/freezing rain and thats in like a 12 hour period

I will be fine with whatever snow I can get.

We need some mets to chime in here on these runs who can more deeply analyze these runs and can decipher model runs whether they look correct or just on crack. The GFS doesnt look right, the setup is convoluted and the EURO i think is being more consistent as well as the NAM (as bad as that may sound)

Anyone from I-95 N/W has a very low/minimal chance of non freezing/frozen precip from this storm. Virtually perfect high positions, arctic air already in place, and a surface low that passes 100-200+ miles SE of the coast does not a rain storm make.

 

Can there be ice/mix, certainly, but with all the players being what they are either a snowstorm or a snow to ice/sleet scenario seems likely. And that is what NYC NWS sees as well.

 The Euro is colder than the GFS because develops the coastal faster than the GFS. We need a quicker transfer like the Euro. I think everyone would take a couple of inches, even if it changes over. I doubt it will change over to plain rain. The airmass that will be in place will be a cold one.

When the wind turns to the ESE, you'll be mighty surprised at how fast the temp can spike up.

This isn't going to end well with a track of the coastal as far offshore and as weak as what the GFS shows, especially for inland areas. We're going to get that initial blast of snow associated with the WAA and that is what the Euro had giving us most of our snow. As the primary dies off the precip is going to fall apart and shut off over PA. Then the coastal is going to form and it's going to look like a piece of garbage, strung out and unorganized with most of the precip well southeast of the area, and likely offshore. We're going to end up with less snow than yesterday if the GFS verifies.

What is it missing? Why is a model always wrong if it doesn't bury us in snow? Its another solution. With that said, the energy hasn't even made it on the coast yet. The models still need a couple days to work it out. But this was a totally plausible solution. I think a snow to ice scenario makes sense and I think the models are too warm at the surface. How many times have we seen cold air hanging in longer than modeled. We will see. An all snow scenario for all , like most want is highly unlikely as of now.

 

I am not saying it couldn't be right. I just do not believe this is solution that will transpire.  It has nothing to do with getting buried with snow.  I very ratherly post on here but when I feel a model is way off its rocker I will comment.

Low level cold air is really hard to erode. I think we would need a strong coastal hugger to warm us up completely for the area to change over to plain rain.

I'm telling u, on an east or ese wind its game over for a lot of us. Well NW of the city will hang tough. Now if the storm is a bit further off shore or stronger and the high doesnt slide too far east, its a totally different story for the city and coast.

But actually they mention rain in their forecast but nothing about ice which I thought was odd.
