Newark (interiors of NJ/se NYS/CT) Sun-Wed June 22-25 possibly hottest 3-4 day period this year (2025) with 2-4 100F+ days, possibly hottest June daily. NYC probably one 100 deg. HI exceeds 105 interior M-T June 23-24.

Is the wind going to pick up out of the NW?

It's pretty dead right now. 

[Snowlover11]

Low of 74, up to 78

[bluewave]

Warm spots like Glendale/ Maspeth Queens already 88° after a low of 83°.

 

[Rjay]

After a low of 75 I'm up to 84.

So, I aw Don's post-thank you.  Added PHI max T RTP today below.

HI generally less tomorrow but actual temp hotter and the overwhelming warmth aloft and w-nw BL flow will make it more difficult for sea breezes. My guess NYC makes 100-101 and KEWR close to 103-104. EPS has been pretty good!

a third 100 degree day possible I95 corridor Wednesday, presuming it makes 100+ Tuesday. 

Despite the weak gradient, large low level lapse rates allow downward transfer of offshore nw wind from between 850-700mb.  

 

I am very optimistic here for 100 near JFK today

80/75 with an overnight low of 75°.

ConEd says not to charge your electric vehicle unless absolutely necessary lol

Let's switch everything to electric and then not able to handle the load when we actually need it, makes a lot of sense. 

One day vehicles will be able to be charged on the go from the frictional energy of driving.

Go to map view and zoom in.  The list has some intersections, see below:

where do you see it in tabular format and can the data be downloaded and put into a spreadsheet?

also why dont they show wind direction?

Even though temps will rise fast now, dropping into the low 80s by 6PM yesterday (for a lot of us) makes a difference in how we perceive the heatwave. My worst memories of past heatwaves is being in the 90s still at midnight or even after.

If we peaked in the 100s and dropped down into the 80s quickly like yesterday I wouldn't care about the heat. This evening and tonight will be atrocious compared to yesterday.

Andover had 0.55 inches of rain on the same day they hit 98?

Plattsburgh reached 101° today. That tied the all-time record that was set August 5, 1955 and tied on August 1, 1975 and August 2, 1975. 

Back to back days of 101 at Plattsburgh in 1975? That must have been one hot stretch-- maybe they'll match that again today?

Wow I got down to 75 degrees. I never expected that. I'm cooler this morning than yesterday morning. 

lower dew points which means it should heat up much faster today and for longer

I think yesterday was worse because of higher dew points.  It feels very cool this morning.

[Dark Star]

What a stark contrast between standing on my driveway vs. under a tree in 100 degree temperatures.  I wouldn't want to be working outside in either location.

38% relative humidity doesn't sound that high from Monday afternoon, but with the dew points at 70 degrees or higher is what we felt...

Look at Valley Stream on that map, just east of JFK, thats a westerly wind, 100 degrees if not more.

 

It will be a race at JFK today to see if they can reach 100° before the sea breeze. The record ridge is so strong that the Bermuda high pressure is building much further north into Canada. So it leaves a little weakness in the ridge near our area that allows a sea breeze south of the Belt Parkway and the Southern State on Western LI.

 

 

[Sundog]

10z HRRRRRRRRRR has 100s right down to the beaches:

[LoboLeader1]

Temp 83/DP 71/RH 69%

 

 

[TWCCraig]

HRRR has the sea breeze staying close to the coast. This should help coastal locations approach and exceed 100

it reminds me of the rain/snow line in the winter, it's the same processes in play too.

it's part of the reason the park is usually cooler, although they were hotter than LGA yesterday

That area where the winds combine will likely be the hot spot across the area. Maybe some 102-103 readings there.

Yes I'm hoping for here.  Long Beach can stay in the 80s as they aren't really part of long island (it's a barrier island like Fire Island and Jones Beach are.)  As a matter of fact, those barrier islands serve a useful purpose as they keep the sea breeze away from long island proper on days like today.

The HRRR is the most aggressive in suppressing the sea breeze allowing JFK to reach 100°. The other guidance is just a few miles north stalling along the Belt Parkway to Southern State. Somebody just north of sea breeze with downslope compressional warming will probably go 102°-104°. Maybe a peak somewhere of 105° from Newark to Central Queens and perhaps NW Nassau.

what was going on in July 2011 that allowed JFK to hit 103 on a wind from the due South lol

JFK has already reached 90 it's the earliest I can remember that happening.

If we have a strong NW flow then there won't be any seabreeze before 4 pm, that's what I'm hoping for.
