Friday looks similar to Jun 27th with the E/ENE flow , clouds and temps in the low 70s during the day.

This is like a lower scale version of that extreme heatwave lol

Same here. Has more of an oven feel outside than sauna. Once it’s over 72/73 dewpoint is when the sauna’s on. 

[bluewave]

You can see how sensitive the Newark is to local sea breezes since it’s right on the water. Was 93° a little over an hour ago on a light SE breeze. But jumped up to 99° last few minutes on a SSW flow.

But it's inland and much hotter than anyone in the city and here of course.

a SSW wind is a humid flow but not that hot.

SE flow is cooler off Newark Bay and SW is warmer off the land there.

We have a SW or S wind off the water, it’s just not a strong wind and Jones Beach’s water temp is 77 today so less cooling influence. It’s disgusting on the barrier islands-I just saw a 90/78 in Long Beach. That’s all the S wind’s really good for today. 

[Snowlover11]

T-Storm just north of me. Literally just missing to my north, if i reach my hand out I might feel a rain drop.

[JonClaw]

Another 100-degree day IMBY. If the Corona micronet site is anything to go by, this summer has definitely been the hottest in recent memory.

[weathermedic]

94/76 at my station with a southerly wind

[jm1220]

High of 96 IMBY so far.

Looks like our 2nd chance this summer for some part of the area going 5”+ with the record dew points and PWATS.

Stations that have recorded at least 5" of precipitation in a day in 2025 through July 19th. Most of these are CoCoRaHS stations.

It’s about time for our August deluge. The warm 77 degree waters will give plenty of fuel.

Definitely real feels arent all that bad today compared to a host of other days

[cannoliman42]

99 degrees near LGA, but 27% humidity. It has definitely felt worse.

The urban jungle used to average lows in the upper 60s in July. Up until the 1981-2010 averages it did. 

Even in rural areas, if your dewpoints are high you're not cooling off either. 

Everyone's warming up at night. The farmland went from 65 to 68 and the city went from 68 to 71, or something like that. So yea rural still averages in the 60s but not as low into the 60s. 

I get that, I'm not denying that it's warming.  But our summers that are more dewpoint driven are obviously going to to have higher lows as well, and the effect is more noticeable where a UHI is present.  Like last night I was in the 70s where some places in the city were literally still 90 or close.

Another issue is the winds stay up in the city at night while they go dead in rural areas, adding to the UHI woes.

Islip reached 95 for the fifth time this year. That ties 2025 with 1966 and 2010 for the second most such days. The record of seven days was set in 1999.

The high temperature potential gets a little lower following each deluge. We were 103°-105° back in June. Then the record rains a few weeks ago. So this warm up only made it to 101° -103°. Maybe when the temps rebound again after the first week of August the max potential will only be 97° -100°. We’ll see how it goes.

I wouldn’t be surprised at all if someone has a flash flood emergency. Meanwhile it’s the hottest day of the season at the beach. We have had 2 heat stroke incidents with people unconscious.

[doncat]

97/77 temp split today.

[Sundog]

Are the storms expected to make any type of progress SE? I feel like they've been in NE PA and SNY for hours now

It doesn’t look like it based on radar.

Yep, some of the backyard weather stations are pushing 80 degree dewpoints on the barrier islands.
