It makes me wonder what actually caused those marine heatwaves out there? Was the land that hot that it caused the ocean to also heat up so quickly, or did the oceanic currents somehow change to create a feedback effect to make long lasting marine heatwaves?  Japan is on the western side of the Pacific and since we're on the western side of the Atlantic, I feel like a similar thing could happen here one day.

 

The marine heatwaves were caused by the record 500mb ridge stalling in place creating clear skies and light winds allowing the seas to rapidly warm below.

Pattern persistence. So we get cooler and more clouds during the weekend with shower or drizzle chances. The best beach days have been during the week especially for the heat like we just experienced last few days. The next heatwave with 95° to 100° potential will be next Thursday and Friday. Models showing cooler and showers clouds chances again for next weekend also. Gets back to the stuck weather patterns which have become so common over the last decade.

[SACRUS]

 

76 / 64 and mostly cloudy.  Partly cloudy forecasts look optimistic.   Cooler / drier  - likely a break in the 3/4 day heatwave for many, enough sun could get the hottest spots inland there but it looks cloudy.   Weekend looks 50/50 - cloudy and scattered storms Saturday warm / humid with a drying out Sunday by the afternoon.   Enough Sun on Sun gets the hottest spots to 90.  Drier 2-3 days - cooler Mon - Wed before ridge builds heights and heat expands east by the 24/25th, with potential strong heat later next week / weekend.  Overall warm - hot / humid beyond there and likely wetter again with ridge building to our west.

 

7/18 - 7/20 :   Warm - Storms chances Saturday, Drying out Sunday / clearing
7/21 - 7/23 :   Cooler / Drier
7/24 - 7/30:  Hotter / Humid wetter - potential stronger heat 25-27

it wasnt actually very hot today, it's just that it's not cooling down like it usually does in the evening-- it's all that damn humidity

The 90° reading for JFK at 10pm was pretty impressive. The all-time 10pm record high at JFK was 95° set back on July 5th 1999. So anytime we are near 90° this late into the evening people notice since it close to the record values. This allowed the record low max at ISP set earlier in the day to hold. A 79° low for anywhere in Suffolk County is very impressive. You can see it beat the previous record by +4°. The warmest low max ever at ISP was 81°.

Historical:

 

1889 - A cloudburst in West Virginia along the small creeks in Wirt County, Jackson County and Wood County claimed twenty lives. Rockport, WV, reported nineteen inches of rain in two hours and ten minutes that Thursday evening. Tygart Creek rose 22 feet in one hour, and villages were swept away on Tygart, Slate, Tucker, and Sandy Creeks. (The Weather Channel)

1936 - The all time record high temperature for the state of Kansas was set when a 121-degree high temperature fried Fredonia. (US National Weather Service Wichita)

1936: This day marked the end of the hottest period on record for La Crosse, WI. From the 5th through the 18th, temperatures climbed to 90° or better everyday, and at or above 100° eight times. During this time six record temperatures were set and the average high temperatures for the period was 101.0°.
(Ref. Wilson Wx. History)

1942: A record deluge occurred at Smethport in northern Pennsylvania, with 30.7 inches in just six hours. The downpours and resultant flooding in Pennsylvania were devastating. The following U.S. records were set at Smethport, PA: rainfall in three hours: 28.50 inches, rainfall in 4 hours and 30 minutes: 30.70 inches and 12-hour rainfall: 34.30 inches.(Ref. Wilson Wx. History)

1942 - A record deluge occurred at Smethport in northern Pennsylvania, with 30.7 inches in just six hours. The downpours and resultant flooding in Pennsylvania were devastating. (David Ludlum)


1970: A tropical depression formed east of the Yucatan Peninsula. As the system developed into Tropical Storm Becky, it provided National Hurricane Center forecasters their first opportunity to study the evolution of a tropical cyclone with the aid of time-lapse movies of ATS (Applications Technology Satellite) photographs in real time, or, The Movie Loop. Becky moved into the Florida panhandle as a tropical storm. (Ref. Wilson Wx. History)

1972: Heavy rain, unofficially measured at 10 to 11 inches, fell in the Mooreland and Mutual areas of Woodward County Oklahoma. The heavy rain caused severe soil erosion, but crop damage was minimal, as wheat already had been harvested. (Ref. Wilson Wx. History)

1986 - One of the most photo-genic tornadoes touched down in the northern suburbs of Minneapolis, MN, during the late afternoon. The very slow moving tornado actually appeared live on the evening news by way of an aerial video taken by the KARE-TV helicopter crew. The tornado, unlike most, was quite the prima donna, staying visible to tens of thousands of persons for thirty minutes. It was moderate in intensity, with winds of 113-157 mph, and caused 650 thousand dollars damage. (Storm Data)

1987 - Cool weather prevailed in the western U.S. Seven cities reported record low temperatures for the date, including Alamosa, CO, with a reading of 38 degrees. The low of 52 degrees at Bakersfield, CA, was a record for July. Up to eight inches of snow covered the Northern Sierra Nevada Range of California from a storm the previous day. During that storm, winds gusting to 52 mph at Slide Mountain, NV, produced a wind chill reading of 20 degrees below zero. Susanville, CA, reached 17 degrees that previous day, Blue Canyon, CA, dipped to a July record of 36 degrees, and the high of 44 degrees at Klamath Falls, OR, smashed their previous record for July by ten degrees. (The National Weather Summary)

1988 - Sweltering heat continued in California, with record highs of 111 degrees at Redding and 112 degrees at Sacramento. Death Valley, CA, hit 127 degrees. Late afternoon and evening thunderstorms in the Central Plains Region produced baseball size hail at Kimball, NE, wind gusts to 79 mph at Colby, KS, and six inches of rain near Lexington, NE. (The National Weather Summary) (Storm Data)

1989 - Thunderstorms produced severe weather in Oklahoma, northern Texas and Arkansas during the afternoon, and into the night. Thunderstorms produced baseball size hail at Stamford, TX, and wind gusts to 92 mph near Throckmorton, TX. Record heat continued in the southwestern U.S. Phoenix AZ reported a record high of 115 degrees, and a 111 degree reading at Midland, TX, was second only to their all-time record high of 112 degrees established sixteen days earlier. (The National Weather Summary)

1992: On this date through the 18th, Thunderstorms crossed Wayne County in western New York State dumping heavy rains over already saturated grounds and swollen streams. Rainfall amounts exceeded six inches in two hours on the 17th. (Ref. Wilson Wx. History)

1993: In south central Kansas, heavy rains in and around Stafford County caused flooding of the normally dry Antelope Creek. Flooding of roads and streets began in Radium during the morning hours. The flooding continued until the morning hours on the 19th. This was the worst flooding in Radium since the spring of 1973. Flooding continued until about 9 am on the 19th. (Ref. Wilson Wx. History)

1996: An F5 tornado struck Oakfield, WI during the evening, injuring 17 people and destroying 47 of the 320 homes in the town. Damage estimates totaled over $40 million dollars. In addition, 56 homes as well as numerous businesses and churches sustained heavy damage. A massive rainstorm in north central and northeast Illinois led to widespread flooding. Aurora reported 16.91 inches of rain, establishing a state record for the most rain in a single day. Other heavy totals included 13.60 inches at Joliet, 9.24 inches in Wheaton, 8.09 inches in DeKalb, and 7.82 inches at Elgin.
(Ref. Wilson Wx. History)

1997: Hurricane warnings were posted along the Gulf Coast from Louisiana to Alabama as Hurricane Danny headed toward shore, first brushing southeastern Louisiana where tropical storm force winds and high tides caused severe erosion. Grand Isle, LA recorded a wind gust to 95 mph shortly before midnight. 100 mph winds and torrential rains, downed power lines, damaged or sunk boats and left flooding in its wake.
Thunderstorms developed ahead of a strong cold front and brought high winds and large hail to the western southern tier, Niagara frontier and Genesee Valley in western New York State. A 74 mph gust was recorded in Orchard Park. Hail, as large as golf balls, damaged crops in Niagara and Orleans counties. Several fires were reported as a result of lightning strikes. (Ref. Wilson Wx. History)

2003: Miles City, MT set their all-time high temperature record with 113°. Highs of 100° or higher occurred 6 times between the 12th through the 19th. (Ref. Wilson Wx. History) .

2008: A man and a woman went outside a home in Standish, ME to get a pair of sunglasses the family dog had taken from 1 of the 3 young children inside. Unfortunately, lightning hit a nearby tree, then traveled through the ground, killing both people. (Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA)

2010: Thunderstorm winds gusted to 72 mph at BWI late evening on 18th. Ref. July PRESTO Page 1

Additionally, a number of locations were within a degree or two of record high minimum temperatures. If not for the scattered convection, there probably would have been more records. Rain seems more effective at cooling than nighttime in 2025.

How does it get that hot without the sun? Most of the day was very bearable, no sun at all and very comfortable right up until 1 pm or so and then the sun came out and there was a surge of heat late in the day. And didn't we have a cold front come through-- all the forecasts were for a cooler night as the front passed and lower humidity and I even saw the word *refreshing* being mentioned.

July 5, 1999 was in a completely different class because it was over 100 that entire afternoon, as late as 6 PM.  Yesterday was more a case of a very late surge of heat, basically at the last moment.

Yep and it looks like we'll get a second surge of cooler drier weather early next week.

Probably downslope westerly winds and the heat coming back east from the city/NJ from earlier in the day. In the summer it happens frequently that the immediate south shore heats up AFTER the cold front comes through because the heat from the city is finally blown east.

Yes, because our atmosphere has become too thick

Add more CO2 and more H2O to the atmosphere and you create a heat sponge that is very efficient at storing heat.  To remedy this situation we'd have to remove both gasses from the atmosphere and thin our atmosphere enough so that it can't store heat that well.

Yes, that really does happen a lot, but usually it's a dry heat we get after the frontal passage.  I guess the dew point was so high that the small amount it fell after the frontal passage still kept it humid for most of the night.

I don't think most people mind the cloudiness in the morning if it keeps a lid on temperatures.  Yesterday morning was like this too-- until the lid came off after 1 pm.

Pattern persistence. So we get cooler and more clouds during the weekend with shower or drizzle chances. The best beach days have been during the week especially for the heat like we just experienced last few days. The next heatwave with 95° to 100° potential will be next Thursday and Friday. Models showing cooler and showers clouds chances again for next weekend also. Gets back to the stuck weather patterns which have become so common over the last decade.

95-100 degrees even for us over here?

The marine heatwaves were caused by the record 500mb ridge stalling in place creating clear skies and light winds allowing the seas to rapidly warm below.

so their equivalent of the Bermuda high stalled and created the marine heatwave and it's been happening every year for like 5-6 years now Chris?

Wow, if that ever happened here....

Yesterday saw some record high minimum temperatures in the New York City area:

Bridgeport: 77° (tied record set in 1968)
Islip: 79° (old record: 75°, 1969, 2010, 2013, and 2021)

Don, looking ahead to August, is there any respite from the heat and humidity? Seems that July has been brutal in recent years with a break in August and then return to hot weather in September.

10pm and still 90 at JFK, 99 heat index. Downslope W flow and still humid. Tomorrow can't come fast enough.

Yeah if we had this during the day with more sunshine we could have made a run at 100 yesterday.

It always feels worse at night for some reason.

Tuesday looks like low to mid 80s with dews in the upper 40s. Probably the best we can expect

Hoping for the South Shore desert to do its job next weekend. I need it to be dry in Patchogue for the Great South Bay Festival. Let's see what we can do to juggle the forecast around to make it happen

Dew point today around 55, makes it feel a lot more comfortable outside today. Temps right now around 77. 

Still holding out hope that the weather for tomorrow during the day, and Sunday day time is nice enough that I can sit pool side.
