86.5. Haven't hit 90 yet in August 

Same here. 88.3 was the warmest. Most days are maxing out between 86-88. Strong southerly sea breeze here keeping us from hitting 90. I'm only about 2 and a half miles from the water

Today is another example of why I think a dew point component makes sense in the definition of a “heat wave”. My high so far is 88. I will probably not make it to 90 again today, actually, I rarely do. But my dew point is routinely 76-78 making the heat index in the upper 90s. 

Our air temperatures may be a bit cooler out here and we may have a stronger breeze, but we make up for it with the higher humidity and dew points. Places that are hotter usually have more drier air mixing down.

I'm at 86.5/76.8 ... temp/dewpoint

87/77

Strong sea breeze here, slowly dropping temps, maxed out at 87.8 at 1:15pm

There's chances of rain later this week Wednesday and Thursday but I don't think it will be enough to put a dent in the drought IMO. I do think the chances for rain events will only increase as we head later into the season but nothing too promising. At this point I'd welcome a tropical system just to get the rain here, just one that's not super destructive.

Kinda surprised it didn't get warmer

We had a decent breeze pick up in the afternoon. We we're modeled to be upper 80's to low 90's with the warmest spots being the farthest away from the ocean breeze.

Only made it to 88, down to 85 now and falling faster

Drier air beginning to mix down from the NW towards the coast. JFK is at 89 degrees, dew point 65. They might have hit 90 after 8pm, which is pretty insane given no incoming solar radiation.

86 for a high here

88 at ISP

89 in the concrete jungle of Central Park

If today fails to hit 80, which it might, it will conclude ISP's second longest stretch of high temps above 80°F, tying 1966. 2010 had the longest stretch. Records go back only to 1963 

Here is the same plot for NYC (Central Park)

Less than a quarter inch here. Not really enough to put a dent in the deficit. We need a real deluge to get us somewhere. The drought on the south shore continues, and will continue.

Probably won't see any good rain here until mid-August at best. Globals are dry for my location for the foreseeable future. Summer 2010 had a localized drought on the south shore, by August leaves we're turning yellow on stressed trees. That will definitely happen soon if it isn't happening already. Late July - mid October 2019 was the last significant dry period here. That caused the fall colors to come earlier despite it being relatively warm.

Barely any rain at all here. Maybe 0.04" at best. South shore of Suffolk county still bone dry. Grass is fried in most spots that aren't watered. Really need the rain badly.

ISP’s 13” in 3 hours in 2014 really continues to stand out for me with all of these extreme rainfall events.

3 hours. More than 1 month’s worth of rain per hour.

That was a truly historic day. A foot of snow is nice, but a foot of rain is another beast. ISP holds the state record for the most amount of rain in such a short amount of time. It really was one of the most significant rainfall/flooding events ever in our area given the time frame and considering it wasn't from a tropical system.

Nothing but a few drops here, but the HRRR still pops a few cells later so it's not all said and done. The south shore of Suffolk County remains bone dry.

Jinxed it. Worst of it will be to my south on the beaches. Going to get some light rain

South shore might actually get some rain out of that cell

Since I am doing research involving the NYC data base, I would be interested in thoughts about how long the tree canopy issue has possibly been affecting temperatures and by what amount, also could we say it was an issue only during foliation season? How strong a wind negates it? 

My belief is that the July 1936 heat wave would have registered something well over 100 F even in today's setting, but that aside, I am looking at comparing data with urban effects considered, and this tree canopy issue is an urban effect in the opposite direction to the urban heat island. My comparisons assumed a gradual rise in the u.h.i. throughout the data set to 1980 and a level signal since 1980 (at some point the urban area gets so large that increases stop happening near its center and are observed further out). The adjustments are more relevant to minimum than maximum temperatures for urban heat islands (typically, if an urban heat island is on the order of 2 F deg, then the average increases will be 0.5 daytime and 3.5 overnight). 

So I am considering adjusting the urban filter that I applied to include this tree canopy issue, any suggestions? Or is there an argument to be made that larger tree canopies have spread through significant portions of the metropolitan area therefore this is just part of the historical trend and something not to be filtered out, since we don't filter out changes to the agriculture of the great plains etc.

The difference is most notable in the daytime in the summer months, nighttime temperatures are more consistent with surrounding observations in the city. In the middle of winter, temperatures at the park are pretty consistent with surrounding areas within the city. In the late spring when trees leaf out, the difference becomes more noticeable. The argument is that the growth over the past couple of decades have made this difference more noticeable. I'm not here to debate whether this is the way it should be or not, but the environment around the park is not the same as it was 30 years ago, let alone 100 years ago.

In regards to the Central Park issue, this was OKX's response when someone asked about it. Wow

That 84.4 looks like an error to me in the saved file on the website. I don’t remember seeing that buoy go warmer than 79° to 81°. It would be helpful if there was a saved regional weather round up for that day out of OKX with the actual buoy reports. 

It does look too high of a number to be true and it's most likely wrong. I'll be honest, I don't particularly recall the water being that warm either, highest being about 81°. 84° would not be an accurate measurement of the average temperature in the top 5ft of the water column. Checking the data, the air temperature was cooler than the water on that day.

When do the sea surface temperatures at these off shore buoys typically peak?  Would the end of August be when the max would be reached?

Depends on the summer but average water temperatures usually peak in August, sometimes earlier, sometimes later. It mostly depends on the weather though. Water temperatures are usually at their highest at the end of heat waves.

The  79°to 80° SSTs at the buoys  south of Long Island are near all-time record highs.

Just combed through the data. 44025 reached a brief high of 29.1 degrees celsius or 84.4°F in 2016. 44025 never had water temps above 27°C (80.6°F) until 2016, it also happened in 2020 as well. This heat wave will bring them very close, top 3 for sure.

At least the city (Central Park) is down to 93 lol

On a mostly clear, hot, and relatively dry day with minimal haze, the satellite picks up well on the heat at the surface. Surface temperatures are averaging over 110°F in some spots. 91 here on the south shore with a sea breeze.

Insane for LGA to reach a high temperature of 97 after 7PM

The fact that live TV stations like CBS and Lonnie Quinn still use Central Park as the go-to temperature observation for the city is pathetic to say the least. Everyone knows it's too cool and not representative of the city. It misleads some people to think it's cooler than it is, thus taking less precaution to the heat. They really had people thinking it's only 87 in the city when every site around it is in the 90's except JFK. They'd be better off showing the temperatures across the area from each station
