I could see the North shore of Suffolk staying mostly snow while areas like the Hamptons pour rain tomorrow afternoon.

Yeah the Hamptons and the forks (especially the south fork) are in their own zone with this.  But the western part of southern Nassau can come close to matching the city in this kind of scenario.

100% accurate. Anything north of LIE has a much better chance of staying all snow. 

I don't think any part of Long Island will be all snow, but it could be more like 80% snow (west) vs 60% snow (central) vs 30% snow (east).

Computing snowfall projections based on 10:1 ratios and 2.0" LE to keep things simple that would be 16" in extreme western Nassau, about 12" in western Suffolk (which is central Long Island) and 6" out by Montauk.

seems the stronger gusts have moved more inland than previous runs. its gunna be amazing looking out that window tomorrow morning.

Taking pictures will be tough when you can't see anything outside! I experienced that in last year's blizzard too.

Chris, if I'm not mistaken our last two verified blizzards were Jan 2016 and Boxing Day 2010?  Jan 2016 was actually verified blizzard for six straight hours at JFK and Boxing Day 2010 was verified blizzard there too?

When do the the better short-range models come out and when should we really start looking at them? I don't think it's around anymore but what happened to the SUNY MM5? That model was always spot on when it came time to use it during the storm. 

it was great with banding! I think it was still around for Boxing Day!  Possibly renamed or something- maybe the ARW?

I like using the HRRR to tell you the truth.  I think the RAP is decent too, but I have no experience with it.

Boxing Day produced the biggest drifts in Long Beach for me since the Feb 78 blizzard.
