Definitely one of those storms that triggers the weather tracking bug. Boxing Day got me. I’m sure this one hooked some new weather geeks.

Maybe 4-6” at MMU? Pedestrian totals, but really good howling winds and cold. Dangerous, even. Good drifting. Morris County does a great job clearing the roads.

Looks like my final snowfall accumulation is around 7.0"-8.0"

Seems about right; I didn't realize it til I went outside to clean up, normal eyeballing didn't work because high winds blew a lot of surfaces.

I have 6+ foot drifts on the side of the house. In front I had 4 foot drifts from the front door all the way to the cars. Two sides of the car are totally clean. Had a couple of houses to do today and my snowblower was pretty useless with the huge drifts.

The spot where I usually measure, which is relatively flat, open and away from the house and trees had about 9" of snow. A part of my driveway (which usually has about half as much due to it blowing away and some nearby trees) had 13", which i assume to be a drift.  Right in front of the garage was a 14" drift which included snow that blew off the garage roof.

Sounds pretty straight forward...it was an unusual storm with a lot of wind and 11" might be a reasonable best effort under the circumstances.  Here's the rub; I took a core from the 9" depth in the middle of the lawn and it melted down to 1.53" which is very high (6:1 ratio and more QPF than I would expect overall).  I can tell you that walking on that snow it was dense not fluffy.  I can also add that for most of the storm it was more like a fog with smallish snowflakes.

I love these storms, but I hate measuring them.  Just as a control, I measured on the patio table and it was 0.0"

It was a quick, but robust shot of snow for the finish. Down to flurries as the band heads east. It definitely dropped a couple tenth's of snow, but my numbers look to remain the same. It's probably the earlier stuff compacted a bit. I'm sticking with 14.5".

That brings my season total to 21.5"

Spot on with the dense snow. Same thing for me here. I'm assuming that's from strong lift not lining up well with the DGZ. Several model soundings that I looked yesterday suggested that as a possibility.

Interesting to note that Bridgeport reported 8.0" snow on 1.34" liquid...also a lot of liquid and a 6:1 ratio.  Maybe it's a Long Island Sound thing.

I think the measurements for BDR are taken from a spotter off the airport somewhere as they don’t do measurements there anymore like many other places in the last 10-20 years

I had the same issue here in west-central CT. The snow is very dense which prevented me from reaching double digits.

JFK closed until 12Z because every time they clear runways, blowing snow drifts back over them. That is most certainly not a quality of dense snow. 

I had to laugh today because I said I’m almost sure LaGuardia and JFK have never before closed for snow amounts this low

Hey @rgwp96 what was your total?  I measured 4.25"-4.50" out there.  Drifts were 7" or more.

I called in 4.2 , mt holly has it as 4.5 . Don’t know if someone else called in more or they just added a little because I said it was still snowing . Def hard to measure . It was also really dense

Seems to happen a lot here.  I'm only a mile or two from the Sound and there's a constant roar in the treetops during these storms.  I think there's a connection. The snow growth theory may have merit as well.

The good news is that while we may have less snow [depth] on the ground tonight, I find it lasts longer here.

Thanks.  I agree, very hard to get a consistent, and therefore accurate, measurement.  However, I like that we are both in the ballpark of 4.00"-4.50" with this one.  The wind and cold were really the story for us inland.

Just went past JFK on the LIRR. No way they had less then 10”.

 I know a spot with the absolutely most insane drifting. On jones island. It’s a combo of a huge open expanse and being on a barrier island. Easily 10’ drifts there after Boxing Day. I’ll grab and post pics tomorrow

..would love to see the drifting going on the north fork..county road 48(sound ave.) will

be tough to keep clear..even the N-S roads are going to have some major drifting..all those open fields

with this NW wind and a foot of snow = trouble..good luck to all those plow drivers!

It is clear to me that the turning point for this storm was when Rjay changed the title on the thread to Fish bomb or something similar I don't even remember the exact title now. Forget Grayson the idiotic name TWC gave this storm. If they are going to insist on the moronic practice of naming winter storms this one should be renamed Rjay.

Too tired to finish reading the thread yesterday. Interesting for me to see the varying comments on this. I'm in Rocky Point, LI north shore, one block off the sound.  Even in the heaviest of the day, the earliest band, the snow was clearly fairly fine.  Even in slow eddies, I could only see occasional flakes up to maybe 0.25" at best.  The density of the snow here definitely surprised me when I went out to clean up.  Could tell snow blower was working a bit harder than expected. When I went to shovel non snow blower areas, found the snow very heavy, and very dense.  Not wet snow heavy, but much, much denser/heavier than expected.  My back is still hurting.  Drifting was interesting as well.  In places exposed to the wind, drifting was a definite factor - but more in the sense of recovering cleared areas and keeping other wind cleared spots clean.  One area of my neighbor's driveway was simply pointless to clear as it very quickly got recovered in snow.  But I didn't notice anything in the way of deep drifting in the neighborhood. Deepest in my yard was maybe 14" in a spot where I'd expect severe drift depth.  So I wonder if JFK's drift problem was similar - just dense snow that in the very high winds still recovered the runways. BNL is closed today due to issues with snow clearing and re-drifting, so I'm curious to see what kind of drifting they had when I'm back to work. 

Whether it was snow growth problem, wind shattered flakes or a combination - I don't know.  I suspect both were a problem out here, but thinking the wind was the dominant issue.

In any case, great storm. Glad it worked out much better for more of the forum than might have been expected.

I think 12" is a fair measurement for here on the south shore in Brightwaters. Snow was dense and pretty heavy. Fun storm- schools closed again today for the kids too.

Under that band now and it is indeed all it's cracked up to be.  Must be approaching 15 or 16" now, but difficult to eyeball.  Drifts have halfway buried cars in my driveway!

This ended up being a decent estimate.  Average of several measurements yielded a total of 16.2" here.  Brings my seasonal total to 23.7".

Excellent event and I simply cannot get over how impressive the winds were here!  I hope this winter has more in store for us!
