a top 10 storm all time in NYC

Maybe they were referring to calendar day snowfall. Sometimes these distinctions aren’t always communicated clearly.

Just saw on the news that someone reported over 35 inches in Mt. Arlington N.J. which is a state record. It looks like it won't hold. Someone from the climatologist office of N.J. went their this morning and measured 22 inches.

False reports are why we can't have nice things.

This was done by a so called amateur.

That makes no sense. First of all, it wasn’t really an outlier. Secondly, you can’t properly measure the snow two days later.

Believe it or not we are still getting snow showers here. 26°

The PNS indicated that the measurement was taken by a trained spotter.

Good point they may have been. I was only half listening as i often do when I have them on. I didn’t even realize this made top ten for a calendar day.

OK the news said an amateur. Not surprised if the news got it wrong. Anyway it does not look like it will stand. The original record apparently was, in all places, Cape May.

I’m glad there’s quality control. Even considering compression, 35.5” should not have shrunk to 22” under the conditions in place.

This from latest 2/3  -  4:26 P.M. PHI PNS Statement.

Have no idea why it was changed from "trained Spotter to "broadcast media"

Also amount dropped from 35.5 to 35.1 not sure why that is either.

From what I've read will take weeks to months to confirm if this amount will overtake the current 34" NJ state record.

Office of NJ State Climatologist will conduct detailed investigation.

[MANDA]

Based on latest KDIX / KOKX radar the last of the precipitation / bands will have exited all land areas of the and be out over the ocean over the next 60-90 mins.

After (I'm estimating about 84 hours) there will be no precipitation falling over the OKX  /  PHI CWA.

Pretty amazing.

If the rumored 22” depth is accurate, it almost certainly won’t stand. This afternoon, first order stations including Allentown and New York City had seen depth come out between 75% and 80% of total snowfall. Newark’s depth was > 90% of total snowfall. 22” would be around 63% of the 35.1” figure and that was reportedly a morning measurement.

Forgetting about records--- and barring seeing a specific message on the discounting of 35... which I have no stake in, but I do have a stake in useful snow measuring. For sure, imperfect. 

There are different standards. once/day SD as per CoCoRAHS does not work for me as most useful, where some NWS offices use the clear the board every 6 hours technique which I think has useful application commercially.  

Attached p 63 of the CoCoRAHS snow guide. 

I had 27" of snow FALL, (right in the middle of the pack),  but the SD I measured amid morning Tuesday in this part of Wantage NJ was 18". This 9" less than fell report is I think easily possible, due to crystal packing in gusty winds, as well as increasingly wet snow during the the 45+ hour storm evolution would result in packing. There may  be some science regarding snow packing down with time? 

Just wanted to make sure the differences were noted between snowfall measuring processes and the large difference in SD vs what fell in 6 holy increments.  Which is best? I argue differently for possible commercial snow clearing application and rate alerts etc. Nothing will get solved with this today.

That sounds about right, I had 27.9 inches and my current snow depth is 22 inches.

[MANDA]

Unreal.  Just when it looked like OKX radar was about to be clear a large area of 20 - 30 dBZ returns blossomed over

western 1/3 of Ct.  Large area of steady light snow!  Maybe a patch of moderate embedded?  System just will not give up the ghost.

 

 

[jm1220]

Light snow here again. Just LOL at this point. 

[donsutherland1]

Perhaps the area of snow can reach Islip and bring the 0.2” needed to bring its storm total snowfall to 12.0”.

[jm1220]

Nice big flakes too. Ground is covered again.

Pouring snow

Apparently blocking IS a good thing.

IF we can snow another hour, it will be day 5

The storm rapidly developed along an Arctic front. Its heaviest snows fell north and east of New York City. Bridgeport likely experienced a localized heavy band within an area of heavy snowfall. Some additional accumulations:

New Jersey: Layton (3 NW) in Sussex County: 4.5”; New Brunswick: 10.0”; Newark: 7.5”

New York City: 7.6” (Mount Vernon just to the north and east of the City: 11.0”)

East of NYC:

Connecticut: Bridgeport: 25.5”; Waterbury: 18.0”

Long Island: Farmingdale (2 NE): 14.0”; Setauket: 18.1”

Much more recently, one saw a roughly similar difference over a somewhat shorter distance: The January 26-28, 2015 storm brought 9.8” to NYC and 6.5” to Newark. Islip received 24.9”.

do you think SW Nassau may have experienced a similar increase in snowfall, Don?

This kind of reminds me of the middle storm in the 2010-2011 winter (the one between Boxing Day 2010 and late Jan 2011) that dumped 9.2 inches in NYC but up to 20" across central parts of the north shore of Long Island.

If it was 2-3 degrees colder in Boston they would’ve had 12” like places very close by did. Was an extremely close call there and models were too cold by just a tiny amount which meant mostly white rain in downtown and where Logan Airport is. Can’t speak for Central Park really but 17.4” wasn’t bad at all, may have been 18” but can’t complain too much. 

Maybe they closed because parts of Boston had a lot more snow than the airport did?  I heard that 18" fell 9 miles away from Logan!

That should be close enough to still be in Boston!  Could you imagine 18" falling in the Bronx while 1.2" fell at JFK?

So Boston Logan is basically our version of jfk right on the water. That is one insane cutoff though can’t think of too many storms with that sharp of a cutoff say between jfk and cpk 

Yeah but that wouldn't happen at JFK because JFK is tucked in.  JFK often does better than NYC in snowstorms here are some examples :  Feb 1961, Feb 1969, Feb 1983, PD2 Feb 2003, Dec 2009, Jan 2016.....also notable is the fact that even in changeover storms like March 1993 and February 1994, JFK either did better than NYC or had about the same amount of snow, another one is the Millenium storm where there wasn't a changeover even though the storm bisected Long Island.  Also the amount of any nonsnow precip from this storm was insignificant, basically just drizzle or a few sleet pellets when we were between bands.

I live on Long Island but the Boston statement is a bit misleading. BOS is Logan which is basically in the ocean. All immediate suburbs did quite well. Cutofff was just insane within a 10 mile radius....

they need to stop measuring snow at these places and using them for official data.  whats this fetish to put airports near the water anyway, do they WANT them to go underwater with the rapid sea level rise going on?

Just saw Hicksville with the highest Nassau total at 17.6". Another yikes. I'd have to say that's a little high but the snow has compacted a good bit and has more water because of the light drizzle so who knows. Next door there's a lowball 9.7" in Plainview. 

17" at Howard Beach lol
