Low of 61.3 this morning. Some elevated wildfire smoke in the skies today unfortunately but the majority of it should stay away from the area

A large part of the western North Slope of Alaska with official forecast high temps over 90F today and tomorrow. This is borderline unprecedented if it happens. There are no weather stations in those 90F+ forecast areas though. So verification will basically be impossible. @alaskawx.bsky.social

The summer of 1966 heatwave was very short compared to our summers these days. The major heat only lasted for around 3 weeks. The summer before and after that period wasn’t very warm by today’s standards.

It wasn't nearly as long as the big heatwaves in the 40s or 50s either, however it's the only time that JFK had three straight days over 100 (three days out of four during this same period in 2010) and both LGA and JFK have their alltime high temperatures from that summer. People who hate heat on here would have gone crazy and thought the world was coming to an end with this kind of super heatwave lol, note how 100+ was reached in three different heatwaves!!! It's now become very rare to reach 100 in multiple heatwaves.

JFK: 3; LGA and NYC: 4; EWR: 6.

That 3 at JFK must be the three straight 100+ from July 1966 Don.  In July 2010 it was 3 days out of 4, I guess the one day in that stretch they didn't hit 100 they were also lower than 98.

I know many like extreme weather and some even root for damage but I wonder if those have ever had damage? It’s not fun and the damage I had years ago wasn’t too bad but still not fun. A close colleague of mine was in the East Coldenham Elementary School disaster, she was in the cafeteria and lost classmates. That experience has had significant long term effects on her mental health. .66” here this morning, I thankfully missed the worst, 63/61.  

I HATE SEVERE WEATHER.  Three people died in Plainfield, NJ last night, may they RIP.

I remember the East Coldenham disaster and mention it frequently.  It happened when I was in high school, we were taken outside that afternoon and told to stand in the football field outside the school, it was so windy that we could barely open the doors to get outside and while we were standing outside in the football field we saw multiple swirling vortices over our heads (none made it to the ground where I was fortunately.) I also hate the sound of thunder and seeing lightning, one hit hear my house in the Poconos years ago and I could smell burning wood and almost went deaf from the loud sound of it.  I also posted damage a microburst did to my roof and balcony at that house, less than a minute of wind violence and so much damage, it was absolutely horrifying.

I found three others (98+ over four days) ,,, one in 1933 (same dates as 1917, July 30 to Aug 2) 98 102 100 98) and also Aug 28 to 31 1953 (98 99 98 100) which were followed by 97 102, so six over 97 there. And in 1993 July 7-10 ran 98 100 101 102 with 97 on the 11th. 

1977 had four at 97+ (July 16-19 ran 98 97 100 102) and 2001 had four at 97+ Aug 7 to 10 (99 99 103 97) ... June 4 1925 ran 99 99 98 96 and Aug 12-15 1944 was 97 102 97 96 (followed by 95 95 96 95). Aug 23 -27 1948 was 95 103 101 100 95. 

1977 hot stretch was similar to 1966's but less severe (at its peak), it's interesting how these extreme hot stretches have an 11 year return period, is there a solar activity connection?

In Long Beach-looks like we get split screwed. Typical. 

You don't want what they had-- trust me. I live on the South Shore to not get severe weather and yet it still happens here sometimes and until I upgraded my network with UPS devices, I would experience electrical device damage on my computers, TVs, air conditioners, from electrical storms.

I was happy to get some GREAT triple rainbow pictures (the first time I've EVER seen that!!!) and see some lightning bolts in the distance (without the sound of loud thunder thankfully.)

It’s still a toss up whether we make it back to 100° this summer. Since some years with 100° in June did like 2024 and others like 2021 didn’t. Our next chance may be later in July.

By the way I think this past June was JFK's best chance to beat that 104 record from July 1966 that I've seen in a long time.  Many reporting stations on the south shore were in the 106-107 range on June 24 (including mine.)  It was hotter here than July 22, 2011 was, which is absolutely amazing.

Do you think within the next 10 years JFK will beat the 104 they set that year and LGA will beat the 107 they set on the same day, Chris?

What confuses me about July 1966 is that usually JFK and LGA need the diametrically opposite wind directions to record their hottest temperatures, how did they both record their all time records on the same day? And Central Park did not?

Very difficult to know ahead of time when dealing with the sea breeze at JFK. Both stations in Ozone Park made it to 104°-105° on the other side of the Belt Parkway. So JFK would have done it if the sea breeze could have held off for an hour or two more.

The weird thing is that the sea breeze went back offshore around 5 PM and JFK hit 102 a second time (it's like a mix line moving around in the winter lol) and it was around the same time I recorded my location record of 106.0  We had clouds for an hour too when the temperatures leveled off between 101 and 102 before it cleared out after 4 PM and the temperatures started climbing again.

69 / 60 - gorgeous day on tap and a nice stretch through at least Sunday of dry weather.  80s today sunny clear - great so cal style beach day - bbq - outside , pool, and fireworks on the bay or beach.  Saturday looks like a copy a shade warmer get the hot spots to 90.  Sunday hotter with more widespread 90s mainly inland as onshore/seabreeze kicks in.   Mon - Wed - warm  - hot / humid but storm chances each day return with onshore component keeping the heat focuses west in NJ but could get to 90 into the boroughs.  Beyond beyond overall warm to hot / humid and wetter with ridge building into the east with stronger heat by the  17th.

7/4 - 7/6 : Dry / clear (80s 4th, 80s - 90s 5th/6th hotter)
7/7 - 7/10:  Warm, - hot / wetter
7/11 - 7/16 :  overall warm - hot / humid / wetter

Today was another very warm day. High temperatures included:

Bridgeport: 90°
Islip: 90°
New York City-Central Park: 88°
New York City-JFK Airport: 89°
New York City-LaGuardia Airport: 92°
Newark: 94°

Today was the third day this year that Bridgeport and Islip hit 90° or above while Central Park did not. That breaks the record of two such days that was set in 2006.

Parts of the region will experience a strong thunderstorm this evening. Afterward, generally warm weather will prevail through Saturday with readings mainly in the middle 80s.

It will turn hotter on Sunday and the heat could persist through Tuesday. Highs will top out in the upper 80s to around 90° in New York City. New Jersey's hot spots will likely reach the lower and perhaps middle 90s.

The ENSO Region 1+2 anomaly was +1.0°C and the Region 3.4 anomaly was 0.2°C for the week centered around June 18. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.47°C and the ENSO Region 3.4 anomaly has averaged -0.03°C. Neutral ENSO conditions will likely continue through at least late summer.

The SOI was +13.30 today. 

The preliminary Arctic Oscillation (AO) was +0.923 today. 

 

It hit 92 here -- I guess JFK gets the sea breeze before we do.  What I want to know is how did Bridgeport hit 90, aren't they on a peninsula that extends into Long Island Sound?

Maybe the ASOS back in 1966 wasn’t so close to the water at LGA. But not sure. The current location is right on the bay near the NW corner of the airport.

1816: In Savannah, Georgia the temperature dropped into the 40's on July 4th. (p. 33 Washington Weather Book 2002 by Ambrose, Henry, Weiss) Chauncey Jerome of Plymouth, Conn. saw several men pitching quoits in the middle of the day with thick overcoats on, and the sun shining bright at the time. (Scientific American, "The Year without a Summer" p. 48)

1825 - A hurricane struck Long Island NY leveling trees and causing damage to ships. The early season hurricane, which originated around Cuba, caused major damage along the Atlantic coast from Charleston SC to New York City. Many were lost at sea. (David Ludlum)

 

1825: A severe storm of tropical origin swept up the Atlantic Coast during the first week of June 1825 with reports of significant damage from Florida to New York City. Shipping logs told of a disturbance at Santo Domingo on May 28th and Cuba on June 1st. Gales were reported at St. Augustine, Florida on the 2nd. The Norfolk and Portsmouth Herald reported "undiminished violence" from the gale force winds for 27 hours, ending on June 4th. The effect of the storm reached well inland. Washington had cold, heavy rain all day on the 4th with high winds laying the crops in the vicinity. The wind also tore up trees by the roots in front of the State House in Philadelphia. This storm impacted the New Jersey Coast and the Long Island area as well with high winds and a two-foot storm surge. A Columbian frigate was driven ashore as were many smaller boats. The largest loss of life occurred along the Long Island shore when a schooner capsized. The entire crew of seven was lost.

1969:  "The Ohio Fireworks Derecho" States that were affected, MI, OH, PA, WV Severe thunderstorms accompanied by wind gusts of 100 mph dumped heavy rains of 4 to 15 inches across parts of northern Ohio causing major flash flooding. 41 deaths, 359 injuries resulted and damage exceeded $66 million dollars. In southwest Lower Michigan, More than 60 people were injured, most of them from a tornado that hit Flat Rock in southern Wayne County. The tornado destroyed a tile factory, carrying sheet metal over a mile. Another tornado injured 11 people about four miles east of Jackson as it damaged a dozen mobile homes. (Ref. For More Information)

1972: Chilly Canadian high pressure brought record cold to parts of the northern Plains and Midwest. Jump River, WI dropped to 27° and Blair, WI fell to 36° setting a record for their coldest July temperature. Also, Jump River had the coldest temperature ever recorded in July for Wisconsin. (Ref.

River flooding in Georgia and Alabama spread into the Florida panhandle on July 5th, and along with six to 14 inches of additional rain from the remnants of Alberto, caused extensive flooding. Flood crests exceed 100-year events on the Apalachicola and Chipola Rivers. Damage to buildings, roads, water systems and other public property was estimated at $40 million dollars. Insured losses to buildings and vehicles were estimated at $15 million dollars. Agricultural losses were estimated at $25 million dollars. (Ref. Wilson Wx. History)

1995: 19 members of a single family were struck by a lightning bolt during a Fourth of July fireworks display in Visalia, NC. A bolt of lightning struck a construction crane, crossed wet ground and surged through a fence, affecting 70 people altogether. Fortunately, no one was killed or seriously injured. It is believed to be the most people ever struck by a single bolt of lightning. (Ref. Wilson Wx. History)

2001: A severe hailstorm struck Scottsbluff, NE producing hail up to 3 inches in diameter. About 12 people were injured with damage estimated at $50 million dollars. (Ref. Wilson Wx. History)

By the way I think this past June was JFK's best chance to beat that 104 record from July 1966 that I've seen in a long time.  Many reporting stations on the south shore were in the 106-107 range on June 24 (including mine.)  It was hotter here than July 22, 2011 was, which is absolutely amazing.

Do you think within the next 10 years JFK will beat the 104 they set that year and LGA will beat the 107 they set on the same day, Chris?

What confuses me about July 1966 is that usually JFK and LGA need the diametrically opposite wind directions to record their hottest temperatures, how did they both record their all time records on the same day? And Central Park did not?

Yes. There was also August 26-28, 1948.

JFK hit 100+ on all three of those days Don? I thought it was 2 while it was 3 at NYC?

Thanks we're one off the lead for 100+ and two off the lead for 98+

I think 1983 was the only one at JFK that had two different heatwaves get to 100+, one was in July and the other one was in August.

Maybe the ASOS back in 1966 wasn’t so close to the water at LGA. But not sure. The current location is right on the bay near the NW corner of the airport.
