NYC Reaches 40" Seasonal Snowfall


donsutherland1

Recommended Posts

With 4.0" snowfall this morning, New York City reached 40.0" seasonal snowfall for the first time since winter 2010-11. Snowfall through this morning has amounted to 40.3".

 

Both the earlier snowfalls that distinguished the beginning of the season and the early date on which NYC reached 40" snowfall strongly argue that NYC will likely reach or exceed 50" seasonal snowfall for winter 2013-14.

 

Below is a chart showing the percentage of cases that NYC reached various snowfall thresholds when December saw Philadelphia, New York City, and Boston reach 8" or more monthly snowfall and additional snowfall fell by January 10.

I thought this was interesting. This is only through October so Central Park has added 3 more in the past month and now has more this decade than the 70s and 80s as a whole

I don't want to jinx this but if NYC gets 4.7" of snow next weekend it would make the 30-30 club...

30" in 30 days...
The short list...
02/24-03/24, 1896.....32.0"
02/06-03/07, 1914.....35.2"
12/26-01/24, 1948.....43.4"
01/15-02/13, 1961.....34.1"
01/16-02/14, 1978.....37.2"
02/02-03/03, 1994.....30.8"

The increased frequency of this is somewhat alarming.

good numbers.  if this was a stock market analysis, you'd definitely say the market is going higher.  

40" by feb 5th is huge and certainly sets the table for a historically significant snow season.  i've always considered 50" the gold standard.

 

i'm about 25 miles south of the city and didnt see a single flake.  38" so far.

Actually it has all the way to the 20th to achieve that

There was a terrible cutoff. Hopefully, the next event will be better for all. Even as litlte as 25 miles north of NYC, amounts were 8" or above.

we managed 2-3 in Woodbridge early on but it changed quick.

This is only the 7th time it has reached 40" this early since winter 1869-70 (145 cases). That's about a once-in-21-year event.

This is the 34th time NYC hit 40" for the season.

9/34 (26%) have occurred in the last 20 years.

In fact, from 1967-68 through 1992-93 (26 years), it only happened one time.

February will likely end up much above normal in the snow department (if not already!!). Then we need to think about March. The fact that the QBO is the way it is, north atlantic blocking is favored in the 2nd half of winter. I doubt cold anomalies will be as notable once we lose the -EPO, but with a favorable atlantic and PNA spikes occurring, my guess is that the Feb 15th-March 15th period will also end up above normal snow. Temps will likely be close to normal during this period but it wouldn't surprise me if we got another MECS and/or several (1-3) SECS before the winter is out.

Does anyone think NYC can make a run at the snowiest winter on record? If this pattern keeps up it could be possible.

One would think that record is very tough to beat but it's def not impossible since we are only in early Feb. Keep in mind the record is 75.6". They need 35.3 more inches...which is a lot and 8.4 " more than our seasonal average of 26.9" It's highly unlikely though.

Anything is possible, but we need another 35". That's hard enough for an entire winter, nevermind the last 6-8 weeks of snow.

 

The fictitious 30 incher for this coming weekend would have put KNYC in striking distance.  I think model fantasy storms should count in the season totals.

 

I also think actual snowfall should not be counted if there was no warning issued.  That makes a lot of sense; why else would so many noses get bent out of shape when the NWS doesn't issue a warning for their backyards?

 

:santa:

It would also mean that the Feb-Apr total is 47"+, which is unheard of. I'll check my spreadsheets.

We also reached 40" at my house in Metuchen, today, with the 2" of sleet we got. Most interesting thing today was 2" sleet (about 6" LE), followed by about 0.5" ZR, which was completely absorbed into the snowpack, such that the 2" of slush I shoveled had about 10-11" liquid equivalent - now that's a tough shoveling - my back is killing me, lol.

Here is how I would break down the possibilities for NYC:

 

45" winter: 99% chance

50" winter: 83% chance

55" winter: 74% chance

60" winter: 66% chance

65" winter: 38% chance

70" winter: 21% chance

>75" winter: 16% chance
