can't blame it on el nino either since last year had a la nina.

I didn't realize April 2023 was so wet-- I only remember the two day heatwave we had with the temperatures in the low 90s.

Rained 4.8" on the 29th and 30th. It's one of those things, it was all in big bunches and right at the end, so it was mostly a dry month (From April 1 - April 21 there were only 2 days of measurable rain and it totaled .4").  

For only the 6th time since records were being kept, Central Park will finish in top 10 for both monthly temperature and monthly precipitation in the same month. 

Previous times:

* January 1937 (8th Temp: 40.2, 10th Prec: 5.97")

* November 2006 (8th Temp: 51.9, 9th Prec: 7.34")

* March 2010 (6th Temp: 48.2, 1st Prec: 10.69")

* April 2023 (2nd Temp: 57.6, 6th Prec: 7.70")

* December 2023 (2nd Temp: 44.6, 9th Prec: 6.66" )

* March 2024 (9th/10th Temp - TBD, Currently 5th for all of March Prch: Currently: 8.24")

I don't know if this falls under coincidence or trend, but 6 times in 150 years, followed by it happening 3x in 12 months is really astounding.

- Over 30% Of all top 10 temp months have occurred since 2010  (38/120) 

= Over 25% (28/108) of all months in the last 9 years (April 2015 - March 2024) are now one of the top 10 temperatures for it's respective month.

March 1-10, 2024 was the second warmest such period on record in New York City.

It was also the wettest such period on record with 4.57" of precipitation (old record: 3.65", 2018).

I was tracking this, and as far as I can tell, it's the only time that we've had even top 5 for wettest month and warmest month for first 10 days.

I know it's only a 9 day start (and it would require temps to stay above 40 degrees in central park for it to be a record for 10 days).

But for first 9 days of March, record for temp (48.5 vs. 48.2) and precipitation(4.54 vs. 3.65). 

I remain utterly fascinated by this Central Park stat:

I've been calculating the 30 year rolling averages for temperature at Central Park. 

Warmest 30 year average

1995-2024: January, February, March (As long as the full monthly average is above 41.0 , which is quite likely)

1994-2023: April, September, December

1993-2022: June, July, August

1986-2015: May

1982-2011: November

1942-1971: October (All of October's top 10 30 year trends occurred in the 1960s and 1970s)

I have no idea if this is random, or part of some peculiar weather system trend. But October is such a bizarre outlier on the general warming trend of NYC. 

9 Years ago, February 2015, was one of the coldest February's on record (3rd coldest in history, coldest since 1934). That also marked the last time any month was one of the lowest 10 in NYC history. 

In those same 9 years, starting March 2015, there have been 27 different months that have been top 10 warmest months in Central Park history, including 5 in 2015 alone. To put it in perspective a full 25% of all months since March 2015 are among the top 10 of their respective months (and 22.5% of the 120 top 10 monthly records for warmth have been set since March 2015).

Thought this was interesting.

Yeah, we are similar to BHO which has had 52 top 10 warmest months to only top 10 coldest since 2010. 
 

 

I have it at 36 to 1 at Central Park since 2010.

LOL, June, AUG & NOV were below average & SEPT was whopping 0.2 degrees warmer than normal.

There's absolutely no sense of objectivity from some of the warm mongers on this site.

To be fair there were 4 different months in 2023 that were top 10 (actually all top 5) for their month in Central Park history and 7 of the last 9 years have 3+ months of top 10 all time for their month. 

Honestly find this quite puzzling, I keep track of Central Park data from the beginning. One thing I track is hottest 30 year average and top 10 30 year average by month.

8 Months have their hottest 30 year average between 2022 and 2024 

3 Months have their hottest 30 year average between 2010 and 2015 

October's hottest 30 year average year is 1968 and all of their top 10 is between 1964 - 1975 (1964, 1967-1975). 

Just a really odd thing. Outside of October, there are 7 top 10 30 year averages before 2000 (6 of 7 between 1990 and 1999) total (out of 110). It's like the entire rest of the year is warming up, except for October.

Our latest preliminary totals as of 1 pm...
Central Park: 0.1"  
JFK: 0.1"  
LGA: 0.6"
EWR: 0.2" 
ISP: T"
BDR: 0.3" 
NWS office (Upton, NY): 0.7"

Other unofficial reports: 
Commack, NY: 1.2"
Monroe, NY: 1.0"
Danbury, CT: 1.2"

 

NYC at 1.8 YTD which might beat last years least snowiest winter

2" before the end of January is uncommon but not super rare. That happened 3x in the 1990s as well.

It's interesting we even had a run of 3 years out of 4 with less than a foot of snow for the season. (94-95, 96-97, 97-98)

That's actually 716 days. It will likely reach 717 days today, as I doubt we'll reach 2" daily snowfall today. It will be a close call, though.

Here's the 2" record (through today):

Weird, I was tracking this on a local database and I thought the old record was from 3-15-1900 - 2-16-1902.

Whoops. My spreadsheet had predicted weather for a few days and I wasn't paying attention. Still interesting that the 2" record was almost covered by the 1" record.

New York City (Central Park) has received 1.4" of snow through 7 am, including 1.0" today. That ends the City's record 701-day stretch without an inch of daily snowfall.

What is a bit amazing though. Still the record for the longest gap between 2" snowfalls in NYC. (2/13/20212 had 1.6" of snow). It's been 721 since the last 2"+ snowfall  (7.3" on 1/29/2022). 

The previous record (that I have) was in 703 days ending 2/16/1902.  

I have this current stretch at 721 days. 

I find it odd (in a random way), that there are 7 storms between 17.4 and 18.1 inches, considering there are only 3 between 15.3 and 17. Just one of those things.

I'm in New Providence, NJ in Union County .and just measured around 16" on my deck. I am not a trained spotter or anything, it was just with a tape measure. It's still snowing a ton here. 

I thought it was interesting that Feb 2018 broke Feb 2017 record in Central Park. First time a record was set and re-set since November 1895/1896 (records only going back to 1870s).
