With the exception being the Sierras/Cascades or the LES snowbelts this is a rarity regardless of the location

Yeah I mean once you push 40"+ for a storm, that's historic outside of the typical areas like you mentioned.  Not saying it's happening with this one, but something to watch.

That storm was pretty isolated though, once west of Suffolk County it was about a foot of snow

It was the 6-8" they got in a hour that really stranded folks on the road.  I'll never forget watching the news after that crazy band hit them and i couldnt understand why the reporter looked like she was reporting from marshmallow land.  Everything was rounded off as if they just had 6-8" of wet snow.  Well they did.  Insane snowfall rates!

I remember that haha that was on Ch 7 WABC and she looked like she was reporting from the top of a cloud!  40" in central Suffolk County and CT!

With the winds and coastal flooding potential now we are talking a storm in another league for the coast. A very heavy wet snow and 70moh gusts would mean major power outages. I was without power for 9'days after Sandy and it wasn't pretty. Especially when it got really cold. This is one is not joke 

That is the one thing that worries me. I can sit out a blizzard, but outages are another thing. I have sump pumps. I have a generator that hasn't been started in years, but also an inverter I can hook up to the car. in 54 years I never lost power in a snowstorm; but snowtober, Irene, and Sandy were another matter. But will this be a wet snow? Why are we concluding this?

The Jan 87 storm stranded many people on the GSP, and that was nowhere near some of the storms we've had since. Timing is the key; we have better warnings now and more social media. 87 took a lot of us by surprise; this won't.

I assume you think this will be of the heavy, wet snow variety?

This hardly matters I'm sure, but what's the potential for the ULL to pivot through the region on Wednesday and give us more accumulating snow?

It does pivot through, but the mid-levels in the atmosphere have no time to recover, so there is little precip. Maybe some snow showers.

SNY I live in Rockland 20 years and have seen some big snows as well , maybe I should say are these # 's just too good to be true is there something that everyone is possibly missing , I know its only model runs and take each for what they are worth but we are talking 40 inches in PA ? Or is there a first time for everything,,I hope its the latter

I think 10" is a great snowstorm, especially in March.  Start relatively modestly with expectations and adjust as necessary.  Forget about 40" or even 30"  That's just fantasyland.  We won't really know where the bigs snows will setup until the banding is already evident on radar.  In several decades of living in the HV, I've never personally seen a 20" snowfall.  I know it has occurred in different parts of the region, but never IMBY.  Historical snowstorms are rare for a reason.

I believe that Paul alluded to this possibility this morning.  Always unpredictable though, but I've seen them put down a few isolated bonus inches at times.

The more I look at this setup, it really looks like the January 87 storm displaced east somewhat.

All that is necessary for moderate flooding is a 2.5 foot surge. A surge around 3.5 feet would get to the edge of major.

Ummm wow. We could easily see major flooding then with a euro situation. This is what is now legit worrying me about this. 

Mans to answer the questions about he heavy wet snow and power outages yes. If we get on the wrong side of the coastal front for a bit and temps spike into the mid 30s your going to cake snow onto trees and power lines. I would be seriously worried about this central Suffolk east

Let me ask you guys a question , are these numbers actually possible ? We have seen models spit out crazy numbers before and MANY times we were real disappointed ! I mean you guys that have been on here a long time or forgot more than I will ever know , can PA really hit 40 inches and can North and West really hit 30 ? If this all comes to be IM IN!

the Lindsay storm had 30 plus in white plains/6 inch/hr rates for a time....it is possible and in the KU book it has happened a few times but that storm stands out in my mind (Feb 1969).....a met or more experienced hobbyist could probably give better info
