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. 

 

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.

I am hoping the EPS idea of the pattern drying out during the eclipse week is correct. But a daily forecast that far out will always be low skill.

ah so maybe that front and low the GFS had yesterday might move out quicker than anticipated and allow clearing by Monday the 8th?

Parts of the area could go over 12.00 on the month with this event and a bunch over 10.00.

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").

It least some of the higher elevations were able to reach average snowfall with the recent storm. 
 

 

Did you notice that all that all the accumulating snow was well north of us?  Even in this so-called colder pattern, the snow didn't even make it into Boston.  It was in the upper midwest to northern new england.  This is what shows me that March is truly a spring month.  We can really only count on snow in January and February.  Any other month is a coinflip, even in a colder pattern.

Good point-- this is how you can get a very hot summer with lots of rain too-- 1983 and 2011 were great examples of this.

Where was this in Janaury?

Screenshot_20240327_100016_Chrome.jpg

1) Only 19% of Januaries 1981-2023 had -NAO (sub -0.25). -NAOs were three times more frequent in Jan during 1955-80 (58%)!

2) This 19% of Jans with -NAO 1981-2023 contrasts with 35% of Aprils during the same years.

3) Actually though, the GEFS chart shows a forecasted -NAO in April similar to that of early to mid Jan. Jan 15-21 near the end of that -NAO was the coldest week of the winter along with two snows.

Check out May too, it's probably even higher than April.

Indeed, 47% of Mays 1981-2023 had sub -0.25 NAO. Also, 47% of Junes and 44% of Julys.

So, -NAO aren't becoming less common, they are only becoming less common in winter and early spring.

Somewhere around 50% is what should be expected with how the index is constructed, so rather than assuming they are getting more common in late spring and summer, they are probably becoming less common in winter and early spring.

 1. Accommodating for calling -0.24 to +0.24 neutral, I estimate 42% of all months to be expected to be -NAO. 

2. In addition to becoming much less common during winter since 1981, they actually have become more common in summer since 2007. @bluewave has posted about a theory that the increased frequency in summer is related to AGW/CC (I think related to increased melting of ice but not sure).

Not surprising given the continuing record WAR and SE Ridge patterns since the 15-16 super El Niño.


Near to record 500mb heights for Canadian Maritimes

On every run of the ECMWF weeklies in the extended range :lol:

Hopefully the weeklies are banned next winter-the last 2-3 yrs they have shown the "big pattern" in the LR only to bust horribly.

I wish I had a dollar for every time they showed a +PNA/-EPO/-WPO/-AO/-NAO/50-50 Low pattern in the long range since 2016
