Anyone know what the highest dewpoints ever recorded in this area are?  Not that we are going to break any records, but I was curious.

84° is the highest on record at JFK and EWR. The JFK record was set in 2016 and Newark in 1995. While the Sussex County records only go back to 2000, your record is 79°set  in 2016. You can see how many hourly records there have been at our stations in the last 6 years.

92 here with a heat index of 107!

Some amazing years on that list!  The only one of the 40+ group after 2010 is 2016.  Shows how our truly hot summers have become endangered by all this humidity and rain

 

How? 

Our average summer temperatures have been near or in the top 5-10 since 2010. 

Also the higher dews lead to higher heat indices which is what affects people the most rather than raw temps. 

This summer will be in the upper echelon with 100+ recorded at several locations this June and possibly this Thursday-Friday.

Looks like 89 is the high for both Syosset (88.9) & Muttontown (88.7) today.

85/78 At my station 

[Rtd208]

Current temp 95/DP 77/RH 58%

[Cfa]

Car thermometer read 82 while entering Connetquot River State Park and 87 while exiting (heading west). A distance of less than 2 miles, pretty much sums up the climate here vs ISP.

[dmillz25]

91 for the high here

[psv88]

90 today

[psv88]

Can’t remember the last excessive heat warning for Suffolk county 

[Cfa]

88/73 split today.

[WeatherAU]

Wow at the 18z 3km NAM SHARP cut-off but radar looks good something incoming for Central NJ all-over-again

[doncat]

92/71 temp split today....currently 87/77.

[nycwinter]

this will be the last heat wave for nyc..finally nothing but delightful weather after that..

Tend to disagree... Latest CFS Weeklies support another one incoming

We could see the svr tstorm watch expanded into parts of the area

DISCUSSION...A cluster of thunderstorms with a history of wind
   damage across southern PA will continue to pose a risk for damaging
   wind gusts this evening. Ongoing within an unstable (2000-3000 J/kg
   of MLCAPE) but weakly sheared environment (<20 kts of effective
   shear), convection has remained marginally organized in several
   bands of multicell storms. Recent radar trends show additional
   convective development ahead of the main band across northwestern NJ
   suggesting storms will likely continue to the Atlantic coast. With
   strong instability in place robust updrafts capable of strong
   outflow winds appear likely. A local watch extension across NJ may
   be required as storms approach the eastern edge of WW427 in the next
   hour or two.

Hit 85/76 here for the high, felt pretty miserable out although we barely hit heat advisory criteria

[WeatherAU]

Oh Yea! CNJ is gonna win this SVR weather

The NWS really needs to address the situation with the trees blocking the sensor. They didn’t seem to take it into account with the official forecast for today. Notice how the forecast did very well for all the other stations. But it was 4° too high for NYC.

I think it was july 20 and 21 2019 i had dewpoints in the mid or upper 70s and temps in the upper 90s those days. July 20th last summer reach criteria too but we were kept with an advisory on the island

I know right?  Snowfall measurements are always too low at CPK.

I just had a bolt strike so close it knocked power out for a few seconds

...Expected: 18 (based on regression equation tied to JFK-LGA-EWR data)

Extreme heat descended onto the Pacific Northwest today. High temperatures included:

Dallesport, WA: 110° (old record: 109°, 1981)
Eugene, OR: 102°
Medford, OR: 104°
Pendleton, OR: 101°
Portland: 102° (tied record set in 1977)
Richland, WA: 107° (tied record set in 1958)
Salem, OR: 103°
Seattle: 91°

As a result of the ongoing bout of extreme heat, Portland will likely experience its second extreme heat event of the year, making 2021 the first year on record with two such events. Portland could also experience 2 or more 100° high temperatures, allowing 2021 to tie or break the all-time record for most such days. There remains a possibility that Seattle could also experience its second extreme heat event of the year.

In some of the long-range guidance that heat could later be followed by another round of heat in the Northern Plains a week or so later. If so, one will see a similar sequence of events as occurred from late June to mid-July.

The ENSO Region 1+2 anomaly was +0.7°C and the Region 3.4 anomaly was -0.3°C for the week centered around August 4. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.48°C and the ENSO Region 3.4 anomaly has averaged -0.23°C. Neutral ENSO conditions will likely prevail into mid-September.

The SOI was +10.26 today.

The preliminary Arctic Oscillation (AO) figure was +0.229 today.

On August 9 the MJO was in Phase 2 at an amplitude of 1.433 (RMM). The August 8-adjusted amplitude was 1.134 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 51% probability that New York City will have a warmer than normal August (1991-2020 normal). August will likely finish with a mean temperature near 76.1° (0.1° above normal).
