Doesn’t look like we will be switching to a drier pattern like that’s anytime soon since the pattern has become so much wetter in the last 20 years. Flooding has been more of a concern here than drought. Models backing off the heat next week due to the tropical low moving up the coast. Makes sense since past instances of 103°-105° heat didn’t have a return to near 100° so soon. New run Old run

Tree ring studies suggest that the 1960s were rated as a 500 year drought. Something that hasn’t been able to repeat in this much warmer climate with increased moisture. So we have been spared peak highs in the 110° to 115° range which would occur here with the much warmer climate of today and 1960s drought and westerly flow. https://ocp.ldeo.columbia.edu/res/div/ocp/glodech/PDFs/Pederson_etal_NYCdrought_revised.pdf

This story is over 20 years old now and the tree growth has greatly increased since then. Central Park Weather: Vegetative Overgrowth Affecting Weather Readings - WABC-TV (New York-WABC, August 22, 2003) - Forecasting the weather is not easy. Government equipment can often be blamed for giving faulty weather information. As Bill Evans explains, a big culprit may be some of the equipment buried in Central Park. Rainfall, snowfall, and the temperature are all vital information recorded 24 hours a day at the weather station located in the heart of Central Park. But meteorologists like Michael Schlacter have serious concerns about the accuracy of the stations data. It sits amid overgrown vegetation and he says thats the problem. The leaves can trigger snow gauges and trees can warp rain and wind measurements. On this hot day, a temperature gauge is in the shade instead of direct sunlight. Michael Schlacter, Weather 2000: "Its kind of like driving a car without a speedometer, odometer, and gas gauge. You are running with false information." The weather instruments at Belvedere Castle have long adorned the top. There used to be a government meteorologist here in the city to keep an eye on them. But now the nearest meteorologist is 60 miles that way. But National Weather Service meteorologists say they knew the weather readings in the park would never be as keenly accurate as the ones at the airports where guidelines prevent foliage from being within 100 feet of the station. Schlacter: "We knew that at times we would have flaky readings, that leaves would fall in gauges, that we would have problems with visibility sensors." [NWS Meteorologist-in-Charge Michael] Wyllie says the weather station is there because it was historically significant to maintain its presence in the park. He says theres been a lot of growth because of the wet spring at so much in fact that temperatures have routinely been recorded lower in the park than at the airports. Wyllie: "We are actually having a micro climate system there because of the vegetation." Imperfect perhaps but nonetheless the system provides the official record of weather for the country's largest city. And Michael Schlacter says its a city that deserves better. Schlacter: "I think New Yorkers deserve a lot better, and I think they deserve the best weather station money can buy." Copyright 2003 ABC Inc., WABC-TV Inc.

Yeah, impressive 500 mb height rises to the north and east of New England during the hurricane season has been steering all the major hurricanes into the Gulf and Florida since the 1990s.

Yeah, we have been fortunate that there haven’t been any droughts of a similar magnitude to the 1960s to early 2000s during this much warmer climate era. But this comes at the cost of more warm season flooding events around our region. Plus much higher dew points even into New England. Last week was the highest June temperatures on record from Long Island right up into New England. But the lack of any strong drought helped keep the duration shorter. Still it was my highest temperatures since moving to just east of the KHVN ASOS site a few summers ago.

The summers began to warm faster in the Northeast starting in 2010. Since then the Northeast has experienced 12 out of 15 warmer to record warm summers. We are on track this summer to make it 13 out of 16. We haven’t had a really cool summer in the Northeast since 2009. All the 3 slightly cooler summers were due to the warmer climate normals. We would often get a cooler summer like 2009 after a series of warmer summers. The winter warming began to really accelerate with the super El Niño in 15-16. So the Northeast has experienced 9 out of the last 10 winters running warmer than average to record warm. This recent 24-25 winter would have only been considered average in earlier 30 year climate eras. We haven’t had a colder winter in the Northeast by historical averages since 14-15. The winter warming across the Northeast has been faster than the summer warming by several degrees.

It had to do with the radar range across the country with the new radars which were installed back then. https://www.weather.gov/okx/Tour_Introduction#:~:text=In 1993%2C the National Weather,as 13 River Forecast Centers. In 1993, the National Weather Service moved from its old office in New York City to this modernized facility in Upton. Placement of the office was governed, in part, by the range of the radar, about 250 miles. Nationally, there are 122 forecast offices like this one, as well as 13 River Forecast Centers. The NWS also operates 21 aviation support Center Weather Service Units and various National and Regional Support Centers. Click here to see all the offices and centers that make up the National Weather Service.

There has been a long and storied relationship between the NWS and Central Park observing site at Belvedere Castle. The quality control was light years ahead of what has happened since the NWS left 30 Rock in 1993. Prior to the NWS leaving for Upton, there were meteorologists that would regularly go over to Central Park from the office to Central Park for all the snowfall measurements. So the accuracy of the snowfall measurements was top notch. We even had meteorologists that used to post here that would run back and forth between the Rockefeller Center office and Central Park to do the measurements by hand. As soon as they left on 1993 and the new ASOS was installed in 1995, the quality temperature and snowfall measurements rapidly declined. The trees began to grow over the site in the 1990s putting the ASOS in the shade especially when the trees were fully leafed out. There were several news articles written with outside meteorologists criticizing what began to happen around 2003 when it became very obvious. I think the NWS fought to keep the Central Park site open as there may have been some talk of closing it. But the parks department was very sensitive to the idea of cutting any of the trees back in Central Park. So in the last 20 years the tree growth has accelerated even more from when the original articles were written. The conservation movement in Central Park has grown very strong. This is generally a good thing. But when your weather observing equipment in under a growing tree canopy, it will take 3° to sometimes 5° off the high temperatures on sunny and warm summer days relative to a grassy clearing in the park like the Great Lawn.

We can see how the 500mb patterns have changed during this -PDO interval in the 2020s. Now we get very strong Aleutian Ridges and weaker -PNA troughs out West. This goes to the PNA variability that has been experienced since 2019. So even with such strong -PDO values, we are getting more changes between +PNA and -PNA. We saw this last winter with the strong to record +PNA for a La Niña. This was also the case with the 20-21 La Niña. Same for January 22. There has also been the tendency for a much stronger Southeast Ridge than was the case from the 50s into 70s. While we have also seen some significant -PNA intervals like in December 2021, the long term trend against these fluctuations is for a more positive PNA. This -PDO era has been more defined by the record marine heatwaves from the Western to Central Pacific. And less of a cold pool formation off the West Coast. But not as dramatic as the EA index with the record heatwaves in Europe. The rising heights near the Azores could also be contributing to the more +NAO even though we have seen Greenland blocking intervals.This has also been associated with the Southeast Ridge linking up with the Greenland blocks.

I like your sense of humor. We would probably have a really good time if we had one of the forum get-togethers. My buddies and I were all pretty big practical jokers back in the school days. The patterns over the last decade have really been a teachable moment for all of us. While the climate models have the general idea about warming over time correct, the regional nuances have been pretty far from what the expectations were. This new subtropical ridging and rapid SST warming in the mid-latitudes wasn’t expected. The old batch of climate models had the strongest ridging and SST warming further north near the subarctic regions. So it’s a bit like running a big science experiment and finding out which ideas were correct and which ones missed the mark. The new -PDO era in the 2020s is more defined by the warmer WPAC than a cooler EPAC. I think this is why we have been seeing more variability between -PNA intervals and +PNA periods. So we get these quick month to month change ups especially out West. But unfortunately we have still been getting strong Southeast Ridges and Western Atlantic Ridges under both PNA phases.

Looks like the next chance for 95° to 100° heat will be early next week as the 500 mb ridge builds again. Models have more of a southerly flow. So the warmest spots should be further from the sea breeze and coast.

More top 10 monthly warmth around the area. Islip and Sussex, NJ recorded their warmest Junes on record. Since the new 1991-2020 climate normals are so warm, all it took was a +3.2 at Islip and +3.4 at Sussex.

Measuring the temperatures under a mature stand of trees will always be 3° to 5° cooler than in a grassy clearing on sunny and warm days. NYC was usually pretty close to the surrounding sites like Newark from 1936 to 1980. This is when the thermometer wasn’t underneath trees. Some heatwaves NYC was warmer than Newark. Many of the 100°+ readings from that era would have only been 98°-99°with a similar sitting to what NYC has seen since the increased tree growth in the last 10 years. Tree growth was slowly becoming an issue from the 1980s into the early 1990s. Then there was a greater shift in 1995 when the new ASOS was installed. This became much more pronounced since 2014 along with the continuing tree growth.

That still remains one of my all-time favorite snowstorms. Probably the most electrified blizzard. The record cold and snow in April 1982 would have been impressive in the 1880s or 1780s.

Yeah, great part of NYC. The whole area from around Prospect Park to the Brooklyn Waterfront has seen a real renaissance over the last 20 years. Gorgeous views especially when we get some snow.

Another top 10 warmest month for the Northeast.

My guess is that this that the expanding subtropical ridges across the planet from Japan to the Eastern US and Europe as the climate warms are driving these multiple records. Notice how the EA has become so positive over time. So the +NAO could be driven by the expansion of these ridges. Plus the feedback from the record marine heatwaves east of Japan across the Atlantic to the Mediterranean. Mika Rantanen‬ ‪@mikarantane.bsky.social‬ · 1d The Mediterranean is now warmer than it typically was in August during the recent 1982–2015 climate period. And it’s no wonder when you look at the atmospheric circulation: a strong upper-level ridge has parked over the western Mediterranean, allowing the marine heatwave to develop. ALT ALT 1 11

Yeah, working outside in that type of heat is brutal. I rode a few miles on the Long Beach Boardwalk back in July 1999 with 100° and a 75° dewpoint. It was pretty intense. But I actually enjoyed the 0° with 50 mph gusts in January 1985 more.

Yeah, models starting to show a retrogression pattern. A piece of the Plains heat may try to come east in early July for a few days in the mid to perhaps upper 90s. But if the ridge axis remains west, then it won’t be nearly as hot as this last week was. That would follow the more historic precedent of no follow ups above 103° so soon. So maybe 95° to 99° for a day or two before the ridge pulls back. Then it’s possible that the WAR retrogrades in mid to late July with more 95° to 100° heat here. But hopefully nothing as strong as we just saw in late June.

The record ridge over the WPAC driving the steep -PDO decline has resulted in the earliest end to the rainy season that the west of Japan has ever seen. Also part of the pattern which drove the all-time June heat the heat in the East a few days ago. So even with a neutral ENSO it’s creating a very strong La Niña background pattern. Very impressive forcing over the Maritime Continent. https://japannews.yomiuri.co.jp/society/general-news/20250627-266163/ Rainy season appears to have ended in various parts of western Japan, it was announced Friday. According to the Japan Meteorological Agency, the season ended in the southern Kyushu region 18 days earlier than usual and 19 days earlier than last year. In the northern Kyushu region, the season ended 22 days earlier than usual and 20 days earlier than last year. The Shikoku region saw the season finish 20 days earlier than average and 20 days earlier than last year, and the Chugoku region was 22 days earlier than average and 24 days earlier than last year. In the Kinki region, the season finished 22 days earlier than average and 21 days earlier than last year. With the exception of southern Kyushu, this marks the earliest end of the rainy season in western Japan since records began in 1951.

Beautiful collection of photos. There is so much Brooklyn history there going back to the Dutch settlement. The neighborhoods from around Prospect Park back to through your area up to Williamsburg contain some of the most sough-after urban real estate in the United States. I was able to find a great old photo from the Blizzard of 1888. https://www.brownstoner.com/history/blizzard-1888-new-york-brooklyn-snow-storm-history-environmental-subway/ Out in the snow in Cobble Hill, possibly Clinton Street near Amity Street.
