In 1962 it was in May and in 1976 it was in April.

it's crazy that JFK hit 99 on May 29, 1969 and never hit 100 in June (until yesterday that is.)

JFK could have reached 105° if the sea breeze didn’t arrive. The Lefferts/ Ozone Park station just to the north on the other side of the Belt Parkway reached 105°. Another nearby separate Ozone Park station also made it to 105°. Newark and Harrison in NJ both reached 103°. This is the earliest 105° across the area since 7-3-1966. So the first 105° readings in this area during the month of June.

There was no sea breeze here and I'm 5 miles due east of JFK.  It hit 106.0 here at 4:36 pm here.

Did JFK really get a sea breeze? They were still over 100 at 5 PM and I was over 100 at 6:20 PM

Going forward, whether it is later this summer or in future years, whenever a potential heat wave in is the forecast, all the news stories will continue to propagate the misleading statement that "NY City has not reached 100 degrees since 2012."

How did it not get below 84 here last night?

We got into the 80s around 10 PM but then hovered in the mid 80s all night.

With the dew point lower, I expected it to get cooler than that last night.

Didn't Westhampton also get to 100 yesterday Chris?

Maybe we all do it again today with it never getting below 84 here last night and completely sunny skies today and an offshore wind again?

My station hit 103 between 4:30p and 5p today. Highest it's ever been. Wind was from the west at the time.

Yes I peaked at 106 at 4:36 pm lol

This was a record event for late June in our area. The La Niña sample size for 103° or greater is very limited for the last 10 days of June. But 2021 was the last time. It turned out to be the highest summer temperatures we experienced that year. 

This extreme event was associated with a very deep trough diving into the West. Current models forecasts don’t show a trough returning to the West as we head into July. So my very early guess is that this could be the only 103° to 105° range we see this summer. But there could very well be another few 100°-102° days beyond this current period.

I was dropping at a slow but steady pace but then just stopped and stayed around 81 or 82 the whole night.

it's also very rare to hold back the sea breeze like that.  If it happens again my guess would be between July 20-31? Like with a November snowstorm, doesn't it take awhile for the pattern to reload?

I think we could hit 100 again today and then our next chance might be in 4 weeks.

Yep, I was in the upper 80s by 10 PM but then it just kind of stalled and fell very slowly after that.

Got down to 79.  86 currently. And we're off.

You're not getting as hot as yesterday though, the atmosphere is "cooler." You already had best case scenario conditions yesterday.

It’s possible that the next chance may be during the 2nd half of July at a lower level than this one was. The trough out West was very impressive. Though the cooler air is highly limited in the Northern Hemisphere with all the record heat, that area did manage to see some record lows. This matches the pattern of recent years with our warmest temperatures occurring with deep Western Troughs. Looks like the rain on the weekends pattern is set to continue.

85 / 70.   Strong heat for the next 28 - 32 hours. More mid - upper 90s and hotter locations may touch the century mark.   Ridge pushed south tomorrow with clouds and onshore flow becoming established - if enough sun some placed will extend the heatwave to 5 days  / 4 days.   Showers storms Thu pm / evening.  Friday 30-40 degrees cooler with onshore flow cooled highs approaching 70 or upper 60s, with some showers/storms around. 

The weekend looks to continue the wet streak although there should be periods of drier / in/out Florida style sunshine.  Sun gets it hot quick and upper 80s - low 90s.  More of the same Sun - Mon.  Loclized storms 1 - 2 inches. 

Drier by Tue (7/1) and through the end of next week. 

Beyond there may be caught between the ridges for a period so perhaps a bit unsettled before ridge build heights and heat north and east beyond.

 

6/25:   Strong heat
6/26 - 6/27:   Cool down - onshore clouds - showers-storms
6/28 - 7/1 :   Steam warm - hot , storms each day
7/2 - 7/4 : Drier near normal 
7/5 - 7/8 : Wetter / caught between ridges
7/9  beyond :  Hotter - ridge heat building north - east

I'm thinking 100 is possible though.  Like in July 2011, July 22, 2011 was best case scenario when I reached 105.6 and still got to 101 in slightly less ideal conditions on July 23, 2011.  I think that was the last time the entire area reached 100+ two days in a row.

[ForestHillWx]

84/72… last day of this for a while thankfully. 

[Stormlover74]

The weekend will hopefully be salvaged. Looks to warm up and while there will be showers around certainly not a washout or a continuation of Friday's weather

Same theme. Just enough rain to keep the rain on the weekend streak going. But not enough for a complete wash out. But there could be a least some rain each day. Though the best beach weather continues to be on the weekdays. So it’s no surprise the models have a stalled front and rain chances for the July 4th weekend with weak waves of low pressure.

Historical:

 

1749 - A general fast was called on account of drought in Massachusetts. It was the year of the famous dry spring in which fields and villages burned. (David Ludlum)

1925 - The mercury hit 101 degrees at Portland, OR, their earliest 100 degree reading of record. (Sandra and TI Richard Sanders)

1953 - The temperature at Anchorage soared to 86 degrees, their hottest reading of record. (The Weather Channel)

 

1957: Hurricane Audrey moved northward, slowly strengthening until the 26th. At that time, a strong upper-level trough led to its acceleration and the hurricane deepened rapidly on its final approach to the Texas/Louisiana border. Audrey became the strongest hurricane on record for June upon landfall, as it reached category four strength. Its acceleration was unanticipated, and despite hurricane warnings in place, 418 people perished in the storm, mainly across southwest Louisiana.

 

1981: Late afternoon violent thunderstorms moved across the region. Allentown, PA recorded a gust to 77 mph, with quite a few roofs blown off, chimneys toppled, windows blown in, several barns blown over, and innumerable trees felled. Power was interrupted to almost 100,000 customers, some without power for several days. Heavy rain caused flooding and mudslides. Philadelphia, PA received 1.91 inches of rain. (Ref. Wilson Wx. History)

1983: A quarter of an inch of early summer snow was reported near the towns of Sharon and Hartford in the higher terrain of central Vermont. (Ref. Wilson Wx. History)

1987 - Afternoon highs of 97 degrees at Miami, FL, 107 degrees at Medford, OR, and 111 degrees at Redding CA were new records for the date. It was the third of six straight days of record heat for Miami. Thunderstorms produced wind gusts to 70 mph at Austin, and gusts to 75 mph at Tulsa OK. (The National Weather Summary) (Storm Data)

1988 - Fifty-two cities in the central and eastern U.S. reported record high temperatures for the date. Highs of 100 degrees at Erie, PA, and 104 degrees at Cleveland OH established all- time records for those two locations. Highs of 101 degrees at Flint, MI, 105 degrees at Chicago, IL, and 106 degrees at Fort Wayne, IN, equalled all-time records. Thunderstorms in Idaho produced wind gusts to 100 mph west of Bliss and north of Crouch, injuring 29 persons. (The National Weather Summary) (Storm Data)

1989 - Tropical depression Allison, the remnants of what was earlier Cosme (a hurricane over the Pacific Ocean which dissipated as it crossed northern Mexico), began to spread heavy rain into southeast Texas and southwest Louisiana. (The National Weather Summary)

 

1990: Borrego Springs, CA hit 122°; their hottest temperature on record. Phoenix, AZ set a daily record high of 120°. (Ref. Wilson Wx. History)

1994: Blistering heat prevailed across the southwest deserts as many daily record highs were set including: Yuma, AZ: 119°, Tucson, AZ: 115° and Winslow, AZ: 103 °F. (Ref. Wilson Wx. History)

1995: Flood in Orange, Madison, Green, & Culpeper Co. as they had between 13.00 and 15.00 inches of rain.
A lifeguard at a camping resort S of Myrtle Beach, SC, was hit by a lightning bolt as he was in the process of clearing the beach due to an approaching storm. He survived. Several people nearby noted “tingling sensations” when the bolt struck. (Ref. Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA)



2006: The precipitation total on June 25th was 5.31 inches, a new 26 year MAXIMUM precipitation record for a day. The old record was for a calendar day was ONLY 3.86 inches on October 8, 2005.

2006: The maximum one hour rainfall intensity was 2.35 inches on the 25th which shattered the previous record not only for June but for any month. The previous 26-year record was 1.74 inches on July 28, 2000. (Annandale Weather Records)

2008: Missouri:
Thunderstorms deluge northern Missouri and sections of central Illinois with 6 to 8 inches of rain. Linneus, Missouri was hardest hit with 8.61 inches while nearby Ethel reported 7.88 inches and Gallatin 6.80 inches. (Ref. WxDoctor)

RIght.  If you account for the Park's tendency Jul 2013 was also.  We'll see how strong the heat can get with the next ridge later next month / Aug.

[donsutherland1]

Historical tidbit while temperatures climb. Since 1869, Central Park has had 39 days with low temperatures of 81° or above. All 39 days had highs of 90° or above. The lowest high occurred on July 3, 1876 when the low was 81° and the high was 90°.

Just the opposite.  I can't say the the Urban Heat Island effect was responsible for THI values over 100 for such a large area.
