Snow Friday 1/19/24: is it a period of light snow (less than 2"), or is there a chance of a 5" swath in part of the NYC subforum? Event OBS.

because NYC metro is still in a snow drought like it or not with only around 2 inches through January 18 and I would bet we will tracking dry slots tomorrow with many areas ending up underperforming and south Jersey getting at least twice as much as the metro...........

January is a plus 5 month with no snow going into this. You are lucky you are getting this week in what will be an awful winter weather month.

Here comes another 7 days above freezing for next week

and we will be analysing the longer ranger model hours wondering when and if we will see any more snow this winter.....

I dated a girl from Massapequa (now my wife) and the commute up and down 135 was very interesting during borderline events. 

I think those Syosset stats are pretty accurate but they are a product of my misspent youth.  If you compare them to BNL there are some obvious differences, but I also find that to be true with Smithtown and BNL certain years.  We're about 18 miles from OKX and Syosset is twice that.

I've long tried to put my finger on a sweet spot, but it's difficult. Part of the difficulty is the data just isn't there to make an objective conclusion.  Best guess is along the north shore between Huntington, or maybe even NE Nassau and Rocky Point.  In most years, the bullseye is somewhere in that area, but in exceptions it can be anywhere; south shore, east end, even Queens.

OKX/BNL is the snowiest spot with a long term reliable record on the island, but it's the only such record anywhere near the north shore and I suspect the elusive sweet spot averages 2 or 3 inches more snowfall than BNL.  In fact that may be the case in much of the north shore region to the west of there.  I took a stab at this almost 20 years ago, but life has interfered with that project:

PS one of these years I'll redo the website and make it more phone friendly (and easier for me to update)

I looked for a sweet spot based on your detailed snowfall maps of the region and I'd say for Nassau County it's near Muttowntown and for Suffolk County (and Long Island in general), it's somewhere between Miller Place and Mt Sinai.  We have snowfall measuring stations there I believe?

The NAM is an obvious, clear outlier as always. Total trash model. Anyway, this is a 1-2 inch snow event for the area iMO. I don’t think the 3 inch amounts happen until you get into central NJ on south. On the bright side, at least it’s going to snow

didn't the NAM do really well with the warm nose for the last storm ?

It’s funny you should say this because I’ve lived in wading River since the 80s, we also had a house in Queens. And it was snowier in Queens by a lot.

Granted, when you move inland, just a few miles toward Brookhaven national lab, you lose the effect of being on the immediate water.

 

But living out there for most of my childhood, I would never say it’s as cold or as snowy, as where I am in Westchester now. 

As queens has warmed dramatically with the UHI and general warming, I would say it’s definitely colder out there than Queens and probably snowier now.

Things remain on track for a general 1"-3" snowfall in the New York City area tomorrow. Philadelphia, Trenton, and Belmar will likely see 2"-4" with that area possibly seeing some locally higher amounts of 6" as it is favored for the development of an inverted trough. There remains some uncertainty concerning the exact placement of the inverted trough. Once one gets north and west of White Plains, snowfall amounts will fall off. The northern Hudson Valley could see a coating to 1" of snow (with more downside risk than upside risk).

Following this storm, New York City will have more snowfall this winter than it had for all of last winter.

Historic Data:

With the PNA's being negative, the probability of this week's storms being moderate or significant in New York City was low. During January, a PNA+ is associated with moderate or large snowstorms. The percentage of storms by snowfall amount with a PNA+ (January 1-31, 1950-2023):

4" or more: 66%
6" or more: 77%
10" or more: 89%

That’s about all it did good on, midlevel warm noses almost always get more aggressive at “game time” like that one was. The ensembles actually did a better job with actual snowfall totals, they had my area at 2.5 inches for 2 days and that was correct

I've always looked for north+some elevation for the ideal combo.  The reason why I selected Mt Sinai is because it has some elevation compared to say, Port Jefferson or anywhere else right on the sound.  Where in Queens did you used to live-- was it near Whitestone? I imagine it was very snowy there too back in the day before UHI.

Muttontown for Nassau County is an interesting story.  They routinely get colder than anywhere on the island outside of Westhampton (KFOK), I've also noticed they hang onto snowcover long after the rest of Nassau County is down to pavement and blacktop lol.

Westchester is another interesting story, back when I was trying to keep much closer track of rain/snow lines for the north shore, the three official reporting stations I'd use were LaGuardia Airport, White Plains and Bridgeport (and sometimes New Haven although they don't measure snow there anymore, but they do report weather conditions.)  One thing I noticed is that the north shore's rain snow line was usually somewhere between LaGuardia and White Plains, but sometimes the north shore did stay snow longer than Bridgeport did although never quite as long as New Haven did.  It's just another way to estimate annual snowfall without official data-- trying to figure out who changes over to rain or freezing mix least quickly lol.

Big winner will somehow be Freehold, NJ. Seems like they always end up squeezing out a little more than anybody else.

I remember in the post Sandy snowstorm on November 7th 2012 they somehow got 14" of snow in a storm that was supposed to change to rain lol.  We can't complain here-- we got 8 inches.  To date, that's my all time favorite early season snowstorm.

It stays below freezing til Monday so at least it'll stick around and look wintry for a few days but yeah we need an area wide 4 to 8 to save us later on

Any snow that we get will melt away next week with the milder temps and rain .

Last winter we didn’t even get a day that felt like winter 

Christmas Day 2022 sure felt like winter with temps topping out in the teens and lows single digits BUT bare ground so the feeling of winter was muted.........

Whitestone. It used to very suburban. Totally changed in density over last 20 years as has most of queens
