Here are all of NYC 100+ days. I find it somewhat ironic that the first recorded 100 degree day (in 1881) was also the latest it's ever happened, 101 on September 7th. https://www.weather.gov/media/okx/Climate/CentralPark/100DegreeDays.pdf 100 Degree Day Information at Central Park (1869 to Present) Last Updated: 1/22/25 100 Degree Facts * Highest Ever Recorded: 106 on July 9, 1936 Most Days by Month: June 3 + July 42 + August 13 + September 2 = Total 60 days Most in one year: 4 (1966 and 1953) Most consecutive 100 degree days: 3 July 8-10, 1993 & August 26-28, 1948 Last time had 100 degree day in September: the 2nd in 1953 (102) Last time had 100 degree day in August: the 9th in 2001 (103) Last time had 100 degree day in July: the 18th in 2012 (100) Last time had 100 degree day in June: the 27th in 1966 (101) 100 degree days before 1900: Sept 7, 1881 (101) and July 31, 1898 (100) All 100 Degree Days Year Date / Temperature (°F) 2012 Jul 18/ 100 2011 Jul 22/ 104 Jul 23/ 100 2010 Jul 6/ 103 Jul 7/ 100 2001 Aug 9/ 103 1999 July 5/ 101 July 6th / 101 1995 July 15/ 102 1993 July 8/ 100 July 9/ 101 July 10/ 102 1991 July 20/ 100 July 21/ 102 1980 July 20/ 101 July 21/ 102 1977 July 18/ 100 July 19/ 102 July 21/ 104 1966 June 27/ 101 July 2/ 100 July 3/ 103 July 13/ 101 1957 July 21/ 100 July 22/ 101 1955 July 22/ 100 Aug 2/ 100 Aug 5/ 100 1954 July 14/ 100 July 31/ 100 1953 July 17/ 100 July 18/ 101 Aug 31/ 100 Sep/ 102 1952 June 26/ 100 1949 July 4/ 102 Aug 9/ 100 1948 Aug 26/ 103 Aug 27/ 101 Aug 28/ 100 1944 Aug 4/ 100 Aug 5/ 101 Aug 11/ 102 1937 July 9/ 100 July 10/ 100 1936 July 9/ 106 July 10/ 102 1934 June 29/ 101 1933 July 31/ 102 Aug/ 100 1930 July 21/ 102 1926 July 21/ 100 July 22/ 100 1918 Aug 7/ 104 1917 July 31/ 100 1911 July 3/ 100 1901 July 1/ 100 July 2/ 100 1898 July 3/ 100 1881 Sept 7/ 101

The warm background state caused Detroit to have its first 10 year stretch of winters without any averaging under 27°. This is directly related to how warm the CONUS, North America, and the Northern Hemisphere has become. Your local winter warm records have been more impressive than the summer ones. Nobody in the Great Lakes would ever want to see a winter warm magnitude like 23-24 was during the summer. It would probably take a megadrought like they have been experiencing out West to pull that one off. Summer flash flooding has been a much greater risk than drought closer to your area. So this has been preventing such high end heat extremes during the warm season. I am also glad for you guys that a March 2012 level extreme hasn’t happened during July. it’s just been too wet during the warm season for any big summer heat extremes in the Great Lakes in recent years.

0.65” so far here. BOS is at -0.9F for the month. That will change quite a bit in the next 10 days

Anyone looking forward to this heat is clinically insane

during the early 90s when we hadn't had any big snow seasons for over a decade, I used to go to the library and read NYT on microfiche and seasons of yore like 1947-48 and 1960-61 and 1966-67 and 1977-78

I like reading these, thanks.

They’re talking about the Thursday fail for most of SNE other than the hill Billy’s in the Berks and VT

Maybe they can hold together at least as regular storms to the coast? The NWS said that was a possibility (Thursday that is)

For NYC too, check out this old NYT article https://www.nytimes.com/1993/07/11/nyregion/heat-wave-records-rewritten-as-east-bakes-and-midwest-soaks.html

what's the trigger tomorrow? it's CAPEy no doubt but I thought the wfront shifts N of the region and we're just sort of neutral in the pigs bum

Were the total number of 100+ days (9) far in excess though? A few of them must have been in June and August in 1993.

Yes actually in some places it lowers the chances of big heat since it affects mins much more than it affects maxes plus more rainfall makes it much harder to have record heat in the summer here.

The overall monthly average high temperatures for NJ in July 2022 and 1993 were fairly close.

You missed my point. Even if a warm background state is in place it does not guarantee big heat at any individual location. I mean, good for it being 26th warmest winter for the CONUS. It wasn't anywhere near that warm here. And this summer I frankly dont care how many heat records melt away in the southwest, I just worry how much heat makes it up here.

I just learned that the latest it ever hit 100 in NYC was on September 7th at 101, it was also the earliest it ever hit 100 in NYC because it happened in 1881 lol. We all believe in climate change but it doesn't affect every location in the same way and not all times of the year are affected in the same way either and it affects maxes and mins differently too. It's a much more complex issue than a +1.5 C rise across the board.

Call me strange, but I wish that flood risk was expanded east. All this miserable wetness, light rain, drizzle, mist, and gloominess and nothing even remotely remarkable to show for it.

The heat was more impressive in the 4 day streak in 1993 than the 5 day streak of 2022.

Yeah. Looks like a big day points N & W.

The background state of the CONUS, North America, and the Northern Hemisphere set the parameters of what individual locations experience. This is why even though the coldest temperatures relative to the means last winter were found over the CONUS, it was still the 26th warmest on record since 1895. The most impressive winter monthly departure was last December which ranked as the 4th warmest on record for the CONUS. This spring across the CONUS was the 2nd warmest on record since 1895.

Or not…

I was alive when this historic heatwave happened and I remember Craig Allen said it was 5.... was 7-11-1993 adjusted downward to 99? Back then Craig Allen said the high was 102 on that date, while it was 97 at NYC. The weird thing is I remember the total number of 100+ days as 9 so if one was taken away, another one must have been added later that summer to make the total unchanged. At any rate the magnitude of the heat in July 1993 was much higher than it was in 2022, most of those days barely touched 100.

Thank you mother nature for the most epic season of Kayaking and Small Mouth fishing.

Finally getting decent rain. But won't be much. Thursday is your classic Albany to VT and NH day. Down to western MA and NW CT perhaps too. Rest of us are watching anvil canopies.

As Canderson mentioned yesterday there is some timeing differences at play . Either way I think the biggest news will be the flash flooding here in cpa. The local water sheds have done a great job this year absorbing and shedding but I think there number is up atp.

July 1993 only had 4 days in a row reach 100° at Newark while 2022 had 5. 1993-07-07 103 78 90.5 12.6 0 26 0.00 0.0 0 1993-07-08 105 82 93.5 15.4 0 29 0.00 0.0 0 1993-07-09 104 83 93.5 15.3 0 29 0.00 0.0 0 1993-07-10 105 84 94.5 16.3 0 30 0.00 0.0 0 1993-07-11 99 80 89.5 11.2 0 25 0.00 0.0 0 1993-07-12 97 80 88.5 10.1 0 24 0.00 0.0 0 1993-07-13 98 79 88.5 10.1 0 24 0.00 0.0 0 2022-07-20 100 74 87.0 8.5 0 22 0.00 0.0 0 2022-07-21 100 78 89.0 10.5 0 24 0.01 0.0 0 2022-07-22 100 79 89.5 11.0 0 25 0.00 0.0 0 2022-07-23 101 78 89.5 11.1 0 25 0.00 0.0 0 2022-07-24 102 77 89.5 11.1 0 25 0.00 0.0 0
