Without the kicker does the storm hang around a little longer or just come closer with more qpf or both?

just comes closer.  the surface low is clearly moving n/ne on mhx radar. the "kicker" vort is wrapping into the southwest side of the system, which should help maintain the more northerly than easterly direction several more hours. would not be at all surprised to see this end up over or just inside the benchmark tomorrow.

HRRR is picking up quite a bit as well, last run has 0.75" liquid to Manhattan almost, and some 1.0" speckles across Long Island. Unfortunately it comes with a sharp dropoff west of 95 but it's been slowly backing west. 

The satellite and radar is something amazing to behold. We're in for a show in the late morning city and coast. Worst appears to be 7am to noon, but HRRR has snow still east of the city at the end of its run at 5pm.

I would shocked if there wasn't a decent surge. It's a sub 950 mb low that means business. I'd kill to be down the shore for this storm. My house down Long Beach Island, NJ is gonna get smoked with Blizzard Conditions and probably 10-15". The UKIE, HDRPS, and NAM rakes the shore points. 

Down here in Atlantic County. Currently getting hammered pretty good. An inch or 2 already on the ground. Winds picking up.

Is the better output on the models them finally realizing the good upper air support that's been around for some time or west jogs or both? Seems more the former to me.

Lee Goldberg mentioned another issue.

He said that because our coastal waterways have ice, there's a danger that ice could come in and damage docks and boats that are moored on them.

Take a video for the board please when the worst comes through later on. I imagine this will be a fun one for you. I'd honestly expect 10-15" there. 

Will do. Ill be awake at 5:30 checking to see if work closed. Doubt ill make it in anyway. Were expecting some pretty decent surge.

that's part of it. the main issue has been convective feedback, with poorly modeled convection on just about all the guidance. they're all initializing the surface low position incorrectly because of that, and then it feeds back later in the run.  with the surface low north/west of where models think it should be now, it is in a much better place to get "caught" rather than kicked out to the ENE as some have been speculating for days.

Thank you for your input. It’s much appreciated from not only me but many on here.

NYC area should be snowing pretty good within the next couple of hours. Some mean banding is showing up not far south now, getting into Ocean County. 

lol we weren't supposed to start snowing until 4 am.

I hope it's not a case of earlier arrival earlier departure.

I want it to snow until 2 pm at least.

Any chance it could stay too far west and LI mixes?

I want the mix line to get it as close as it possibly can, the best snows are close to where the mix line is.

We have zero danger of mixing so I hope it just keeps coming further west.

This seems to happen a lot with these models (including the Euro) and yet people still go by their output without remembering how many times they were wrong and what the margin of error was.

Sometimes I feel like we need a "cone of uncertainty" with these storms too.

There were always different scenarios laid out with the low track and uncertainty communicated. This is just the kind of thing that can cause havoc with a 50 mile track shift or some better upper air dynamics as we're seeing.
