I think that's the key...the wind direction. The DC-Baltimore-Philly corridor got on the west side of the low with a westerly component to the wind and CAA.

Here, we have that type of scenario setting up with this storm. The peak winds are modeled as being either N or NNW from NYC on west. LI and east will have an easterly component in all likelihood, but, being on the coast, tend to do well anyway.

This makes logical sense to me and am inclined to agree with you.

I think we need to separate the areas. It's clear, NYC, Eastern NJ and LI will get dumped on.

We don't have to worry about 10 mile shifts.

GFS, NAM and SREFS all show 1.50"-1.75" for NYC.

That's as unanimous as possible for a pounding snowfall.

RGEM shows 20-25mm from NYC east. That's around 1".

Nothing to worry about folks. Nothing has changed. Were in good shape. It's inside the benchmark

Yeah, almost an identical run to 18z. Maybe a hair weaker, drier (except SNE), and east. But if you reran the model 10 times with 15 minute intervals between initial data, most runs would probably differ to a greater extent than 18z and 0z. This kind of consistency is comforting in the short range.

However, for those on the western fringe, this minuscule shift looks a lot worse on the graphics. But obviously we won't know where the snow sets up until tomorrow.

WOW!! Hour 27 depicting 80-85 knot winds at 850 mb. That's almost unheard of

It's unreal, same things its been showing for 12z and 18z which brought 55-60kt gusts down on bufkit tomorrow evening on Jersey shore and LI...70kt arrow was right above it where mixing would allow with no inversion up to id say 200oft at least

its sort of the reverse of last Feb 5 though less extreme. Everyone near Philly on south knew they were getting blasted while we were nervously watching the difference between an inch or 6. It sucks being on the fringe of a storm, like being near the rain/snow/sleet line and not knowing what you're going to wake up to

It's impossible to predict precisely where the meso-scale dynamics will be best but with thunder snow and banding I believe some lucky or unlucky folks are in for a record book event. It will come down to watching the radar, mesoscale models, data and nowcasting.

Do you really think thats possible? I know that they dynamics and banding will be great with this storm, but 06's band was an absolute monster

Alpha, your radar image there just might be confused with the current radar at this time tomorrow. Just sayin'... Best of luck!

I think many are forgetting this is subforum doesn't just have the immediate NYC area included. Last winter I tried not to gloat for that very reason. The superthreads and now subforums have more than one area in them. It's ok to be excited of course.

As far as the 0z runs go, this last minute bombing out thing had me concerned this entire time. The gradients can be pretty insane with this type of setup.
