Yep, lots of rain recently. The issue just gets worse and worse every year as the instruments get further buried in foliage. 

They don't have the money to cut it huh?

I still don't see that heatwave from 1953 or 1993 ever being equaled.  102 in September is absolutely unreal lol.

How many 90 degree days did NYC and JFK have in 2022? That 49 number for Newark seems rather high and doesn't fit the profile of the other summers around it which were hotter.

1983, 1991, 1993, 2010 were all much hotter summers.

Along with 1995, 1999, and 2002.

Yes, those were the last ones with extended heatwaves.

That NWS longest heatwaves page is a great guide to how our summers used to be.  We didn't see extended heatwaves like that even in 2010 although it had the most 90 and 100 degree days I've seen.

It would take a microburst over Central Park taking out a bunch of trees.

Yeah, moving the ASOS into the shade in 1995 really skewed the values. In the roughly 30 year period since 1996 NYC has had only 461 days reaching 90 vs 817 days at Newark and 631 at LGA. The previous 30 year period from 1961 to 1990 featured 550 days in NYC with 689 at Newark and 410 at LGA.

Harrison has become the new 90° day leader across the area surpassing Plainfield from 1961-1990.

Huge actually since Newark wasn't moved from a forest to an airport. 

They run 2° too hot, nyc 2° too cold.   Just average them to make yourself happy. 

Question though for you.  What's the difference between solar shades that all official stations use vs natural shade?  Aren't both in the shade?  I know underneath the stations matter (concrete vs grass), but can't find much about why different types of shade matter.

1999 and 2002 still had no problems getting extended heatwaves though.

2010 should have the record for most 90 degree days though, it was our hottest summer by a mile.

Chris if we just go decade by decade, and compare NYC, JFK, LGA AND EWR, how do they all compare for the following 10 year periods with average number of 90 degree days:

 

1980-1989

1990-1999

2000-2009

2010-2019

It’s very difficult to cut anything in Central Park. It’s not run by the Parks Department like other NYC Parks. It’s run by the Central Park Conservatory. They receive millions upon millions of dollars in donations from some of the richest people in the world, so it’s not a money issue. I have a good friend who I worked with at Columbia/Barnard who was a gardener at cpk and said it’s incredibly corrupt. 

As far as the heatwave potential. Just look at the heat waves in the Pacific Northwest and France over the last few years. Major heat domes that crushed all time records by as much as 10 degrees. The 1953 heat wave was caused by a heat dome. If that same heat wave were to happen today the highest temp would likely be 105+.

I dont mean to rain on the foliage parade, but the outlier isnt CPK…it is LGA…by far

 

EWR…19% increase

LGA…53% increase

CPK…13% increase

 

The LaGuardia number is way out of whack with the other two. Central Park may be a little low. but the LaGuardia number and what’s going on out there is highly suspect in being accurate.

Why don't they just move the equipment to where it was in 1993 and prior? I would put it right in the middle of the Sheeps Meadow.

The exact reasons I listed above. The global elite running a corrupt organization. They treat the park like their own backyard. The large enclosure for the instruments with fencing is unsightly. So deep in the trees is exactly where they want it, and exactly where it will stay.

Wouldn't being under a tree canopy mimic cloudy conditions/effects on the ASOS?

There is a reason temps are in line with other stations until full leaf out occurs.

But the instruments belong to the NWS no? They should be able to move them to wherever they want them to be?

ah they are worried about people stealing the instruments (hence the fences.)

LGA is interesting. 

A few years ago I read that the max UHI effects are in Western Queens/Brooklyn and Manhattan. 

Since LGA is just west enough to be in that zone I guess it's gotten worse over the years?

Their lows have gone through the roof as well.

Again Central Park isn’t like other parks in the city. It’s, its own entity run by the most powerful people on earth. They could care less about the NWS. 

If the NWS really wanted, can't they just trim back everything that is growing directly over the enclosure? It's better than nothing.

73 / 40 another beaut! today.  Approaching or low 80s in the warm spots.   Tomorrow a touch cooler with the clouds pushing in but still mid / upper 70s.  Tue - Fri - cut off and unsettled with 1 - 2 inches in the forecast through May 16th.  Beyond there timing looks to clear out by the weekend 17/18.   Beyond mid month near normal - no sustained significant warmup or cool.  Still think the progression get us much warmer to hot for a period in the final 10 days, other wise riding near normal overall.
