Yep I did so too

Yes it's a complete shock and people had to go to storm shelters just like they would for a tornado. Satan's Storm, what a name! Burnt cotton fields requires some intense heat.

this *surface temp* thing belongs in a category all its own https://www.science.org/content/article/move-over-death-valley-these-are-two-hottest-spots-earth Death Valley holds the record for the highest air temperature on the planet: On 10 July 1913, temperatures at the aptly named Furnace Creek area in the California desert reached a blistering 56.7°C (134.1°F). Average summer temperatures, meanwhile, often rise above 45°C (113°F). But when it comes to surface temperature, two spots have Death Valley beat. A new analysis of high-resolution satellite data finds the Lut Desert in Iran and the Sonoran Desert along the Mexican-U.S. border have recently reached a sizzling 80.8°C (177.4°F). More than 11,000 World Meteorological Organization manned and automated weather stations measure air temperatures in the shade, in ventilated hutches about 1.5 meters above ground level. But vast swaths of Earth's surface, especially in remote regions, lack these instruments, leaving them out of the record books. SIGN UP FOR THE AWARD-WINNING SCIENCEADVISER NEWSLETTER The latest news, commentary, and research, free to your inbox daily For the past 2 decades, a pair of Earth-observing satellites equipped with NASA's Moderate Resolution Imaging Spectroradiometer (MODIS)—an instrument that measures everything from ozone levels to phytoplankton abundance—have scanned the entire globe, day in and day out. In areas without cloud cover, MODIS measures the infrared heat emitted by surfaces to take their temperature—essentially, how the soil, dirt, or ice would feel if touched. Surface temperatures tend to run hotter than the air above, especially on sunny days when surfaces are heated both by air and the Sun's radiant energy. "Think of your car sitting in a parking lot on a summer day and how the handle burns your fingers. Or the sand burning your feet at the beach," says ecologist David Mildrexler of the conservation organization Eastern Oregon Legacy Lands. In 2011, Mildrexler and his colleagues gleaned from MODIS data that summer temperatures routinely soared above 60°C (140°F) in arid regions, with a high of 70.7°C (159.3°F) in Lut in 2005. Since that study, software improvements have sharpened MODIS's resolution from 5-kilometer pixels to 1-kilometer pixels, bringing even hotter spots into focus. Lut hit its all-time high in 2018, a record the Sonoran, in a weird coincidence, matched the next summer, Yunxia Zhao of the University of California, Irvine, and colleagues report this month in the Bulletin of the American Meteorological Society. But with its "consistently hot footprint over a large area," says Mildrexler, who was not involved in the present study, "the Lut Desert has really emerged as the hottest place on Earth." Zhao and her colleagues uncovered other superlatives. The maximum temperature swing in a single day was 81.8°C (147.3°F), from –23.7°C (–10.7°F) to 58.1°C (136.6°F) on 20 July 2006 in China's Qaidam Basin, a crescent-shaped depression hemmed in by mountains on the Tibetan Plateau. And the coldest spot on our planet? No big surprise: Antarctica. But a satellite reading of –110.9°C (–167.6°F) in 2016 is more than 20° chillier than the coldest air temperature recorded in 1983. It's unclear whether climate change is driving up surface temperatures, Zhao says. But she notes that the Sonoran's highs coincided with La Niña, a climate oscillation featuring cooler surface temperatures in the central Pacific Ocean and drier desert conditions. Higher temperatures are bad news for desert creatures being pushed to the edge of their heat tolerances. "These extremes are really laying it on the ecosystems," Mildrexler says. On the flip side, he says, the data reveal an impressive cooling effect of forests. Trees tap water with their deep roots and dissipate heat through transpiration, he notes, which cools their canopies and the surrounding air. "That keeps maximum temperatures down and protects biodiversity." And that offers a lesson for urban planners, Mildrexler says: Greener really is cooler.

https://community.netweather.tv/topic/69523-heat-bursts/ Sometimes known as heat flashes these are a pretty rare phenomenon. These have been well documented in the US and South Africa and are caused by either by a downburst of air from collapsing thunderstorms or from katabatic downsloping of hot air funneled and focussed through mountain valleys. There are apocryphal reports of incredible heat bursts temperatures: 188F in Abadan, Iran, 158F near Lisbon, and 152F at Antalya, Turkey. The hottest certified heat burst temperature was 110F recorded at Kimberly, South Africa, during the passage of a thunderstorm. The temperature rose from from 67F at 2100 to 110F at 2105 and then fell back to 67F by 2145. Stumbled on this by chance in my archives A letter by F. B. Parkinson of Madibi Mines in Kimberley South Africa "At 9pm on the 20th September 1911, a thunder cloud approached from the west, bringing with it a squall of wind that caused the temperature to rise in a few minutes to 110F. By 9.45pm, it had fallen again to 67F which I expect the temperature before the squall. I do not think my thermometer responded quick enough to register the highest point but it is safe to say it rose 40F in 5 minutes." Here's a recent one which occurred in Adelaide in early 2009: "On the morning of January 29, an exceptional nocturnal heat event occurred in the northern suburbs of Adelaide around 3 a.m. Strong northwesterly winds mixed hot air aloft to the surface. At RAAF Edinburgh, the temperature rose to 107°F (41.7°C) at 3:04 am. Such an event appears to be without known precedent in southern Australia."

a firsthand acct https://www.reddit.com/r/weather/comments/6zjtby/did_the_140f_kopperl_tx_heat_burst_of_june_1960/ 1birder • 2y ago I lived on a farm outside Kopperl when this happened. I was nine years old and I remember waking up in the middle of the night when our old window water cooler went off. It was eerily silent and then the house was hit by a very strong and HOT wind. My father decided we needed to go to the storm cellar outside the back door and we stayed in there for quite a while. Later we saw the large advertising thermometer at Riddle's Bait shop in Kopperl which had burst from the heat. On the news we saw photos of someone's cotton field and all the plants were scorched. Very, very strange but I had no idea this was such a land mark event. I wrote three comments in different places about the event that you might be able to read if you search my name. I don't know why anyone would doubt that this happened. DFW news stations have shown video taken at the time that clearly pictured the scorched cotton crop. More damage may have been shown but that is what I remember most clearly....along with the shattered thermometer at Riddle's Bait shop. As far as an accurate exact temperature I doubt that could ever be confirmed unless someone in Kopperl was "into" weather and had good instrumentation. The Meridian Tribune is a good county weekly newspaper and they could run something asking for information from others who lived through the event. I was only 9 so someone who was older at the time would be better able to give details. This was a very strange event but I remember being much more frightened when we had to go to the storm cellar during tornados.

For example, a well-documented heat burst in Kimberly, South Africa, saw a temperature rise from 67°F to 110°F in just five minutes.

hey what about us in Nassau county?

its hotter here too in SW Nassau but somehow we get grouped with the barrier islands for some odd reason.

I have written about this extensively, there were burnt crops and even burnt trees and burnt wooden doors.

really? well, London hit 40c a few summers ago so why can't we lol

wow 25 is a HUGE number of 95 degree days, 1993 is WAY ahead at Newark.... 1993 and 2010 being one and two matches my climate experience here. 1944 is absolutely amazing for that era with 20, it's good to see the Hall of Fame summers at the top!

to be fair 60s and 70s are not hot lol, 80+ I'd agree with you.

1955 at the top matches NYC's 16 that year Interesting that LGA used to be cooler than NYC (up to and including 1993 I think.) 2010 matches JFK (they both had 11 that year, the very best summer we ever had!)

Yay some sanity has been restored !! 1993 at the top of the 100+ list lol. 1949 is a close second !!

wait, is that Forky haha?

99 would be a huge disappointment....

2006 doesn't even make the list for the hottest summers lol lol how are 1948 and 1949 at the bottom of the list, they were much hotter at NYC, JFK and EWR. This goes to my idea that LGA heated up with more car traffic, there was clearly much less traffic in the late 40s, so LGA was cooler than the other sites. 1993 isn't on this list at all, when EWR had 9, NYC had 3 and JFK had 2 days of 100+? LGA doesn't match my climate experience at all, EWR is a much closer match actually.

are we even sure we're getting *heat*? I just saw the forecast now says the sun won't come out until next Thursday (why do I feel like Annie, saying that out loud in my head lol.) And now we have a phantom rainstorm on Wednesday which didn't exist before now? I thought something can't be created from nothing-- where did this phantom rainstorm come from?

only one 80 degree in March (the last day of the month and only for the first half of that day) and cool and rainy for April (yuck).

He forgot about our cool and rainy April lol

April was extremely cool and rainy and please don't give me the bogus average temp *stat*

Can we get one of these for Nassau County too? I am consistently hotter than JFK even though I'm considered to be on the *south shore* 1 mile south of Sunrise Highway but north of the barrier islands by over 2 miles.

I don't think anyone gets these fabled sea breezes unless they live on the barrier islands like Long Beach. For a sea breeze to get where I am at, it has to be at least 20 mph otherwise it only comes in after the high temperature has already been reached. That's how I know there was no sea breeze here last Thursday, the highest temperature was recorded at 4:30 PM. We can easily hit 100 on a SW wind here in July. The temperature drops after 3 pm but the high of 100+ is reached around 1 pm.

By the way, there was no inland superiority last Thursday we had zero sea breeze -- one of my sensors actually recorded 93.7 at 4:30 pm on the north side of my house, but I don't record that number because it's near the roof of my house. But based on the 94 you listed there, maybe it was accurate? I still don't like the idea of being 4 degrees hotter than the airport especially on a westerly wind. I know I was hotter than JFK here in SW Nassau, I just can't say 4 degrees hotter. I went with the average of all 4 sensors I use and so went with 92. We were definitely hotter than JFK, I just can't say 4 degrees hotter. At least 92 for sure though. I'm not north of JFK, I'm 5 miles almost due east of JFK. What could cause southwest Nassau to be hotter than JFK-- also a compressional airflow?
