Over the Newton/Sparta area earlier, we had two distinct cloud formations that were trying to develop something.  I even ran through a brief shower just outside of Newton, heading towards Sparta around 4:45.  Just barley enough for one or two swipes with the windshield wipers.  There was a tiny blip on radar and the only one around for hundreds of miles.

When saw this around 630pm I checked radar, nada.

Absolutely nuts 

Even in the suburbs it's still in the low 80s past 11PM

[SACRUS]

 

Dew point temps up to low 70s here from 68

[dmillz25]

Wasn’t expecting yesterday to be the third 100 degree day of the year for me. Crazy

[wdrag]

IF NWS issues a flood watch, will start a thread. Its marginal right now but I expect more or less what WPC has posted this morning with isolated max rainfall of 6".  No thread at this time.

Corona and Brownsville maxed out at 103°.

LOL at Manhattan. Manhattan is the hottest borough. Likely hit 102 there.

ps I don't consider heat historic unless it hits 100 everywhere (including coastal areas).

It's like with HECS, I don't consider March 1993 on the same level as January 1996 (I don't really care how much snow the South or the Mountains got-- it's supposed to snow there.)

It looks we can hit 100 today as it's already in the low 90s here and it's not even 9 am yet lol.  The only issue will be clouds, we have been in and out of clouds this morning (looks like they are of the altocumulus variety).

 

For me to consider heat historic it has to hit 100 all the way to the coast the same way it has to snow 20 inches all the way to the coast for me to consider a snowstorm an HECS.

I think JFK can hit 100 today we're already in the low 90s here.  The only issue is clouds, we've been in and out of clouds all morning here.

Low 90s here, I can make a run at 100 today as long as the clouds stay away.  We've been partly cloudy all morning.

you know as well as I do those are inflated lol.

There are no scientific standards being applied with regards to siting (the same can be said about Central Park.)

I question it when it’s in direct sun. But when it was in shade it was 96

you may hit 100 today we're ahead of yesterday's pace (already in the low 90s here)

The heat really hasn't been as strong as what we had in late June (not just the highs but the temperatures in the morning).  Manhattan *probably* hit 100 but we can't be certain, I am 100% certain they hit 100 in late June though.  That was some historic heat when it hit 106 here and then 103 the next day.

Down into the upper 80s now, thank god we won't be baking at 90 degrees at 1AM

We really need to stop building brick buildings and brick houses.  They are basically ovens.  In my time in the SW and in other places that hot, I noticed how well their buildings cool off in the evenings-- and so quickly.  We need to start building more housing with stone and clay.  Homes built with this material removes heat very quickly.  I really don't care about our winters anymore, they are no longer relevant, we need to build housing that removes heat as quickly as possible.

Already 88-90 in Long Beach. I’m sure the seabreeze will be cranking there soon but might just hike up the humidity.

2010 was legendary- beginning to end. Fantastic winter finishing up on Feb 26 with the “snowapocalypse” to the early March wind event , to the fantastic early Spring to the classic hot but lower dewpoint summer, to the great finish with Boxing Day. 
 

Plenty if storms in all seasons but plenty of great weather days. One of best years ever. 

That whole period was probably the best period of weather EVER in the tristate area.

I'd start with the 2009-10 winter going all the way through the 2015-16 winter 

great winters in 2009-10, 2010-11, 2013-14 and 2014-15

30 inch snowstorm in January 2016

below zero VD 2016

historic 2010 summer

historic 2011 heat

hit 100 in 2012 and 2013 too

August 2011 deluge

August 2011 earthquake

Irene

Sandy

September 2010 severe wx outbreak

 

[wdrag]

Will make my final decision on an OBS-Discussion thread for the upcoming rainfall which I think may produce small pockets of FF within the general 3/4-4"---iso max of 6" I think is possible.  Primary event Noon Thu-Noon Fri (16z/31-16z/1), but preceded north of I80 by scattered heavy showers/iso severe 4PM-10P (20z/30 -02z/31) today.  

Most vulnerable via variability in the modeling - cant be sure where to lock it in but for our subforum between I84 and I95. Todays 12z SPC HREF will be my primary guidance, along with other supporting modeling --HRRR etc.

if there's off and on rain there's no way you're in the mid 80's.   

it'll still be pretty humid and uncomfortable I bet with dew points in the mid 70s or higher

the forecast had a high of 84 for tomorrow, I assume that'll happen when it's not raining lol

Those actual neighborhoods are the warmest in NYC. Corona got the compressional warming ahead of the sea breeze front yesterday. If the airports were located away from the water, then they would have been closer to the 102-103° range instead of topping out at 100°-101°. That 2° differential is what you would expect to see when further from the water like LGA. Newark didn’t really get into the compressional warming ahead of the sea breeze front yesterday like Queens did.

Aren't bricks kiln dried clay?

no way keep that thing away, I want it to be like late June, hopefully it stays down there lol

well the clay I saw used in the SW was different, it was basically adobe clay

The Pueblo peoples of the American Southwest built homes out of adobe, sun-dried earth made from sand, clay, water, and organic matter.

it's probably because thats a concrete jungle and the densest most highly populated part of the city.  But I don't take 103 degree temperatures seriously.  If I wanted I could stick my thermometer out in a sunny part of my yard and record even higher temperatures than that.

Today it looks like the sea breeze might stay away until later so we have a much better chance at 100+

The back to back 106 and 103 I recorded last month was the real deal though, same exact siting as in July 2010 and July 2011 and it was hotter than either of them at their peak.

Those are professional thermometers that are shielded and aspirated. So they are getting the accurate temperatures for those urban areas. Low rise sprawl in Queens actually gets warmer than areas where skyscrapers cast shadows during the day. They did a recent study that it also adds more to UHI at night since it allows the ground level to absorb more heat than in places like Manhattan with more shade from the skyscrapers.

I just don't see how it's possible as the heat wasn't anywhere near as anomalous as June's was when I hit 106 and 103 on back to back days. Although I suppose it's possible, my car thermometer recorded 106 a few times in the part of Queens I describe below.

I don't disagree about the skyscrapers making it cooler, I have driven around the city in the past and northern Queens was consistently the hottest part of the city, especially that area when you leave the Mid Town Tunnel and just before you hit the Grand Central.  It's because density of population and extremely high traffic volume, that part of Queens is at least 5 degrees hotter than Manhattan on the other side of the tunnel (and this is year round not just in the summer.)
