On a different topic are we going to get a big northern lights display from this? https://www.newsweek.com/nasa-satellite-extreme-solar-flare-us-states-blackout-map-2088388 Large parts of the United States faced a radio blackout on Thursday following a strong solar flare from the sun. The "extreme ultraviolet flash" was captured by NASA's Solar Dynamics Observatory satellite. The solar flare, categorized as X-class in scale—the highest scale, was triggered by an active region of a sunspot on June 19 at 11:50 p.m. UTC. Radiation from the X1.9 blast caused a shortwave radio blackout over the Pacific Ocean, leading to a loss of signal at frequencies below 25 Megahertz (MHz). Amateur radio operators, especially in Hawaii, may have noticed the signal loss. Solar flares are intense bursts of radiation from the sun. The most powerful explosions in the solar system, they can can contain as much energy as a billion hydrogen bombs, according to NASA. Solar flares are classified according to their intensity, with X being the highest on the scale. X-class solar flares can cause planet-wide radio blackouts and long-lasting radiation storms.

wow what the heck was going on in 1949 lol, was that the 1940s version of 2010? I wonder if JFK had many 100 degree days that summer, I know they had three in a row in 1948. Come to think of it, 1948 and 1949 sound a lot like 2010 and 2011....

to be fair EWR was also hotter than NYC before the foliage problem happened (I'm referring to 1988, 1991 and 1993). But we can use just EWR data if you prefer. Just going by EWR data, 1949 and 1993 have the most 100+ days It makes me think we need lower heights to reach triple digits back then than what we need now (because of more moisture in the air now.)

this is exciting as the two models taking turns forecasting a 30 inch snowstorm for us vs 3 inches of rain lol

The question though is, at least for our part of the country, do we need a stronger 500mb ridge to achieve 100 degrees than we needed in, for example, 1944 or 1948 or 1949 or 1953 or 1955 or 1993?

yes and weighing them relative to each other is also important (as is sometimes applying them to one part of the season vs another.)

Exactly, getting to 98 or 99 is as annoying as a 98 or 99 on a test. 100 is perfection in both cases, so that would be ideal. 105 for extra credit lol.

Great news. I don't really care about Monday, maybe we'll finally have an exceptional day, not the mediocre heat of every summer since 2013.

But was it also easier to hit 100 back then because of lower moisture in the air (I'll use 1949 as an example even more than 1993 which is more recent.) So back then lower heights were needed to hit 100 than what we need now to do it?

Chris please note how 2022 is only on this list once, while years like 1949 and 1993 are on this list multiple times, they had many more 100+ days than 2022 did. 1993 is on this list twice while 1949 is on this list a whopping three times. It does seem like it was easier to hit 100 back then with lower heights, it must be because of lower humidity levels back then, more like a desert than the tropical rainforest we live in now.

That sounds more like 1953 which had two of our most extreme heatwaves we've ever had with 4 100+ days split evenly between both (and our all time September record of 102).

July 1993 had more 100+ days and the 100+ extreme heatwave it had in July was more extreme than the one in 2022 (it hit 105 the all time record at that time twice back then) and the extreme heat was much more widespread in 1993 as it covered the entire area-- NYC hit 100+ three days in a row and JFK two days in a row. It seems like we need higher heights for such extreme temperatures than we did back then (maybe it was easier to be hotter back then because the amount of moisture in the air was lower back then.)

Average temperature defines warmth but not hot. Here are the rankings I found: By the way, AI agrees with me and it seems that number of hot days correlates with average temperatures too. Here is AI's answer: What is the hottest summer on record in New York City? AI Overview The hottest summer on record in New York City was in 2010, with an average temperature of 77.8 degrees. This summer was hotter than the previous record of 77.3 degrees set in 1966, NYC has had a warming trend for years but there hasn’t been as many super hot days. In fact the 12 year gap between 100 degrees is the longest since 1881 - 1898 (and the 2nd longest in recorded history). Last year, despite being the warmest in NYC history by a significant margin (.6 warmer than any other year) the high was only 93. Here is the hottest summers page for NYC (AI agrees with me AI Overview New York City has experienced some extremely hot summers, with the hottest ones often occurring in the late 20th and early 21st centuries. The hottest summers since 1869, based on data from the National Weather Service, have all been since 1960, with 2010 being the hottest on record according to TypePad. The summer of 1966 had the hottest average monthly high temperature, while July 1999 had the hottest average daily temperature. Here's a breakdown of New York City's hottest summers: 2010: This summer is often cited as the hottest, with an average high temperature of 86 degrees Fahrenheit between June and August according to Yahoo. 1966: While 2010 had the hottest overall summer, 1966 holds the record for the hottest average monthly high temperature according to TypePad. 1999: This summer had the hottest average daily temperature in July. 1993: This year had the most 90-degree days during the summer months (35 days). Other Notable Summers: 1983 and 1991 also rank among the hottest summers in NYC's history. I also use Typepad for both summer and winter records, this site is a veritable bonanza of information. https://thestarryeye.typepad.com/weather/2012/07/revisiting-new-york-citys-hottest-summers-.html New York's five hottest summers (since 1869) have all occurred since 1960: 2010, 1966, 1993, 1983 and 1999. The fact that just one of the years is from this century may surprise some since these years were so warm worldwide. The summer of 1966, New York's second hottest on record, has the honor of having the hottest average monthly high temperature. Although July 1999 was the hottest month on record based on mean daily temperature (average of the day's high and low), the average high in July 1966 was hotter than July 1999 by 0.1 degree, 90.3° vs 90.2°. However, July 1999's average low was 3.5 degrees warmer (72.6° vs 69.1°) and that's what easily put it on top. Although 1991 and 1993 had the most 90-degree days for a calendar year, each with 39, 1993 had the most during the summertime period. It had 35, followed by 1966 with 34 and 2010 with 32. 1991 had 31, ranking fourth. https://www.weather.gov/okx/heatwaves This is the NWS Heatwave page for NYC National Weather Service New York, NY NYC Heatwaves Page Weather.gov > New York, NY > National Weather Service New York, NY NYC Heatwaves Page Current Hazards Current Conditions Radar Forecasts Rivers and Lakes Climate and Past Weather Local Programs Longest NYC Heatwaves Longest Heat Waves - 90 degrees + in a row (through March 10) Days Dates Temperatures 91,91,91,94,98,99,98,100,97,102,94,90 92,97,97,93,96,97,93,92,90,98,90 98,100,101,102,97,94,94,91,90,90 90,94,92,97,95,98,94,96,93,90 92,96,98,95,92,93,94,94,94 93,92,96,98,97,100, 102,92,104 91,93,91,91,91,94,99,101,95 93,94,91,94,92,91,93,93,91 96, 95, 95, 96, 97, 90, 92, 91 91, 92, 91, 94, 93, 94, 96, 95 98, 95, 98, 94, 95, 94, 96, 93 97, 102, 97, 96, 95, 95, 96, 95 91,91,93,95,95,100,100,94 93, 93, 91, 94, 96, 90,96 93, 93, 95, 94, 96, 99, 97 90, 93, 96, 99, 96, 100, 102 94, 93, 94, 98, 96, 93, 97 94, 95, 96, 93, 94, 94, 93 98, 100, 90, 95, 100, 97, 93 92, 97, 100, 101, 91, 90, 90

I remember we had a Con Edison controversy (what else is new lol) when this happened a few years ago and the power went out in specific neighborhoods and not in other neighborhoods. I think that was in July 2019 when we had back to back 99 degree days with a heat index of 117 (at JFK). On a weekend too.

Thats my favorite kind of heat.... the specific definition of hot that the NWS uses is number of 90 degree days and they even rank summers based on that on their page. Top heatwaves are ranked by number of days over 90 consecutively and hot summers are ranked by number of 90 degree days overall. No argument about the lethal quality of high dew points, thats why I have argued that removing water vapor from the atmosphere is much more important than removing CO2. We can remove water vapor from the atmosphere and make pure drinking water out of it.

There's a possibility our airports might have to shut down from extreme heat.....

Long live 1966 and 1993 and 2010 and 2011 some of our hottest summers on record, notice that EWR and JFK hottest days and hottest summers match up well, Walt!!

1928 - A farmer near Greensburg, KS, looked up into the heart of a tornado. He described its walls as rotating clouds lit with constant flashes of lightning and a strong gassy odor with a screaming, hissing sound . (The Weather Channel) I wonder what caused that *strong gassy odor* inside the tornado..... fertilizer combusting?

Number of 90 degree days are what defines *hot* You can have a very warm summer with elevated minimums and with a high average departure without it being a hot summer.

Records: Highs: EWR: 98 (2012) NYC: 98 (1923) LGA: 98 (2012) JFK: 94 (2012) Lows: EWR: 52 (1956) NYC: 49 (1914) LGA: 55 (1959) JFK: 55 (2005) Historical: 1682 - A major tornado ripped through southwestern Connecticut, passing through Stratford, Milford, and New Haven, and then into Long Island Sound. (Sandra and TI Richard Sanders - 1987) Tony wow, so maybe 2012 will be an analog to this summer? 2010-2013 had summers similar to what we might be about to embark on.... 1682 tornado, I wonder if that would have been recorded as an F3? There certainly were more strong tornados in this region during that era, you listed 2 for yesterday also.

Yes 2013 had our last 7+ day heatwave (at NYC). The 2010-2013 period was more like what we had from 1991-2002 and prior to that from 1944-1955.

some of our heavy hitting summers in that list like 1949 and 1966 and 2010 !! lol it's funny to see a record at Central Park from 1888 not having to do with the big blizzard.

thats absolutely amazing and what I'm hoping for. It's going to be very hot, let's make some history!

In my experience the compressional heating will be down here near Sunrise Highway. The contrast of the water temperatures didn't make much difference in April 2002 or 2010 either. Long Beach might be in the 80s while Valley Stream is 100+ We made it past 90 easily on a SW wind over a week ago. A NW wind will be at least 10 degrees hotter here. No sea breeze before 4 pm and by then we will already have exceeded 100. On days like this our temperatures rise as quickly as Newark's does (notice how JFK's hottest days and years match up well with EWR's) and we usually exceed 100 by noon or 1 pm at the latest.

Isn't this what happened in the 1944-1955 when we had those 7-12 day heatwaves with 95+ and 100+ temperatures? I know you're all about climate change, but that was a cyclic pattern we had from 1944-1955 and which repeated itself from 1991-2002, so maybe that cycle is returning?
