I remember we had back to back days in the 90s as late as mid September as Cat 3 Hurricane Emily grazed Cape Hatteras and missed us wide right.

 

I was in Central PA so we missed that but in a few months we'd have our best winter ever

Yeah I remember it was in the 20s for lows early in November and then we had the 80 degree high on November 15th a day after the NYC Marathon (a real Indian summer) and then it was all cold after that, basically a storm every 3 or 4 days and almost wall to wall cold right to the end of March.  First wintry storm was a snowstorm between Christmas and New Years.

_______________________________________________

With only 2.62" in June, the met-summer total for 2021 is currently 23.36" which is ranked second  -- 2011 remains ahead at 25.23" and 1975 is third at 22.40" while 1989 fourth at 22.36" -- seems then that 2021 has a chance of finishing as wettest met summer. It needs 1.88"  more to beat 2011.

(1903 not in the above list had 20.43" thanks to a very wet June ... 20th place 1928 above moved well up the list for summer with 20.50" as June also quite wet). 2003 is well up the list thanks to a very wet June, its JJA total was 19.87" but it was well outside this list for JA.

The same is true for 2006 which had a total of 20.79" but only 12.24" of that in July-Aug. 

A third example is 2009 with a summer total of 21.38" thanks to 10.05" in June.

2007 had almost the same summer total as 2006 (20.62") but qualified for the above list in 15th adding 6.55" inches from June. 

Current top twenty for summer totals ...

 1. 2011 (25.23) ________ 11. 2003 (19.87)

 2. 2021 (23.36) _______ 12. 1942 (19.82)

 3. 1975 (22.40) _______ 13. 2018 (19.15)

 4. 1989 (22.36) _______ 14. 1971 (18.88)

 5. 2009 (21.38) _______ 15. 1889 (18.55)

 6. 2006 (20.79) ______ 16. 1990 (18.37)

 7. 2007 (20.62) _______ 17. 1871 (18.22)

 8. 1928 (20.50) _______ 18. 1919 (18.16)

 9. 1903 (20.43) _______ 19. 1884 (17.62)

10. 1927 (20.01) _______ 20. 1967 (17.57)

Note that seven of the top 13 are in the period 2003 to 2021. 

Half of the list dates back only to 1975 (the most recent 47 cases

with 106 others taking the other half, note three cases from 1967 to

1975 and the only other semblance of a cluster was 1919 to 1928

with three.

High for the day yesterday was 97 here.

Current temp 77/DP 70/RH 81%

[CIK62]

The last 6 days of August are averaging 83degs.(75/92), or +11.

Month to date is  77.3[+0.9].         Would end at 78.4[+2.4].        More likely 77.4.

78*(80%RH) here at 6am, hazy blue.      80* at 9am.    84*(75%RH) at Noon.        Fell back to 83*, now back to 84*(80%RH) at 3pm.   Low haze, fog and sea breeze.

Only 87* here yesterday.

GFS keeps moving putative IDA to the east,{A N.O. Cat. 3 Job?}and now we can get some rain next Wed./Thurs. from leftovers.    The holiday period would then be nice and BN.    btw.   Katrina was 902mb, 99L gets to 930mb maybe?     It has to pass Cuba/Yucatan successfully for this to happen.

After record warmth in June and a pullback of the heat in a July, the heat is coming on strong in August. Even Long Island is seeing impressive heat for August. This is only the 8th August at Islip to reach 5 days of 90°.

Morning thoughts…

Today will be partly sunny and hot. High temperatures will likely reach the lower 90s in most of the region with some places topping out in the middle 90s.  Likely high temperatures around the region include:

New York City (Central Park): 90°

Newark: 94°

Philadelphia: 92°

Normals:

New York City: 30-Year: 82.1°; 15-Year: 81.9°

Newark: 30-Year: 83.5°; 15-Year: 83.4°

Philadelphia: 30-Year: 84.6°; 15-Year: 84.3°

The very warm weather will continue through tomorrow before it turns cooler for the weekend.

Oh no lol the bride of the wedding I’m going to is going to freak lol

[Intensewind002]

Hit 90 and 92 back at home the past two days, looks like a fun little heat wave im missing out on. Not even that humid either, dewpoints were only in the 60s

all depends on where the front stalls-some models are reasonably dry N and E of NYC

[SACRUS]

85 / 74 very tropical.  Some storms possible later to coincide with the arrival of the high humdity and dewpoints.  One more day of the heatwave and in some cases day 5 tomorrow (Friday 8/27) before front and some storms /clouds linger through the weekend Sat 8/28 - Sun 8/29.  Ridge rebuilds Mon (8/30) and Tue (8/31) and if enough sunshine the net shot at 90s.

 

Beyond there as we open next month all eyes on the remnants of what will be Ida come north from the Gulf TX/LA border and traverse the Mississippi valley before exiting or coming up the coast as a trough/front approach the east coast the middle/end of next week.  beyond there it looks to return to a warmer/humid flow.

[bluewave]

It wouldn’t be a surprise if we find a way to pick up more measurable rainfall this weekend. There were only two weekends since the Memorial Day weekend with no rainfall. So my guess this is probably a new record for the summer season.

WOW 1980 really rocked lol.  I'm sure JFK was just as hot.

Tomorrow will be the 50th day this year with a 70° dew point. We have never had 6 consecutive years with 50 days before. So the consistently high dew points are a big part of our new subtropical climate.

Currently 92 here, DP 69, RH 50%

These dewpoints are getting annoying and uncomfortable.  Between the bugs, mold, mildew, and mushrooms growing in my garden, I'm ready for way cooler and drier days.  

Maybe September?

If we believe the gfs september starts off rainy and cool followed by dry pleasant weather thru labor day weekend

90/77 at my station (high so far of 91)

CP at 1pm is 87. Every other surrounding station is 90 or above except JFK with a SW wind.

Which is exactly why we need to start on some geoengineering projects to lower sea levels and use up that excess ocean water.

JFK has corrupted data because it's right on the Bay.  We have already reached 92 here in SW Nassau by noon.  I'm 4 miles due east of JFK.

Just because it gets a sea breeze first, doesn’t mean there are any problems with the temperatures. Wantagh is currently 87/74 with a very humid sea breeze. Farmingdale a little further from the shore is 90/71.

We’re at the time of year where the seabreeze doesn’t make the conditions cooler. The temp goes down but humidity goes up.

The SSTs are peaking  later this year than recent summers. Notice the upper 70s ocean temperatures now from the Jersey Shore to the LI South Shore.
