Yeah, we were discussing this prospect a few weeks ago when this new paper was released. The authors have been interviewed about their findings since then. The shift to persistent 500mb ridging and SST warming across the mid-latitude Pacific may be an inherent response to a warming world which the research indicated occurred in previous warming eras for the earth. If we continue to see this block of warming and 500mb ridging continuing into the 2030s, then the new model simulation that was run could be onto something. Time will tell. https://insideclimatenews.org/news/18072025/southwestern-drought-likely-to-continue-through-2100/ But in this case, the phenomenon can last far longer than the usual 30-year cycle of the PDO. But if, as we hypothesize, this is a forced change in the sea surface temperatures in the North Pacific, this will be sustained into the future, and we need to start looking at this as a shift, instead of just the result of bad luck.” Todd was able analyze drought conditions during the mid-Holocene period 6,000 years ago, a period in Earth’s history when the Northern Pacific warmed and the Southwestern U.S. experienced hundreds of years of drought. That led to a warming of the North Pacific that was similar to the PDO that drives drought in the Southwest, but in this case, the drying lasted for centuries. “As soon as we saw that, you know, we started thinking about what’s happening today,” Todd said. Using an ensemble of historical and future climate models forecasting climate and precipitation patterns until 2100, they found the PDO-like negative phase continues through this century. But unlike the mid-Holocene period’s warming, which was brought on by vegetation change, today’s is driven by greenhouse gas emissions. Certain models revealed that the change in the ocean pattern was less about vegetation absorbing solar radiation, Todd said, and more about warming in general. In many ways, Richter said, what people are seeing on the ground is outpacing science.

This was the 5th 90° day of the season at Newark moving into 4th place on the all-time list. There were 4 NYC micronet stations which reached 100° also. So among the warmest stretches that our area has seen from late June into late July.

The dewpoints still look elevated Monday into Tuesday before dropping a bit Wednesday. But not looking like a repeat of the nearly 100/80 experienced back in late June. It’s rare for us to ever really experience dry heat here like they get out West.

The one consolation will be the 850s won’t be as high. So we probably max out 97° to 100° instead of the 102°-105° in late June. Plus it looks like the dew points will be lower than late June and today.

Yeah, unfortunately more major 95°-100° heat next week as the long range models underestimated the ridge again. New run Old run

Nice drop from 93° to 84° here with the thunderstorm.

It’s interesting that none of those great Arctic outbreaks of the 1800s could rival February 1934 at Newark. Was the only -14° low temperature and the coldest month at 18.6° since 1843. The only time Newark may have been colder was back in January 1780 when there was a -16° report in NYC.

The July -PDO will be one of the lowest we have seen as the record marine heatwave near Japan continues.

The last cool summer here was in 2014. But it wasn’t as cool as 2009 which had the coolest June and July since the 1940s. Our summers switched to much warmer and 2010. So there have been no cool summers with 15 or lower 90° days since the 15-16 baseline jump in temperatures. We would frequently get a few warmer summers followed a much cooler one. Now it’s all well above the historical 90° norms with no cool summers anymore. As you can see on the charts below, we had plenty of those cooler summers in the 1940s and 1950s.

Those summers were pretty far down on the list compared to the summers since 2010. Nothing back then compared to the type of heat we have been seeing regularly in recent years. We would get a warmer summer followed by a much cooler one. We haven’t had a much cooler summer like the ones which were frequent in the 1940s and 1950s since 2009.

Yeah, 1867-1868 was their 2nd snowiest winter behind 1995-1996. But they often waited until after the snow ended to measure back in those days rather than the more frequent measurements of today before compaction. So it’s possible that 1995-1996 would have been eclipsed if they measured as frequently as we do today. https://news.ucar.edu/14009/snowfall-measurement-flaky-history Time Series Summary for NEWARK LIBERTY INTL AP, NJ - Oct through Sep Click column heading to sort ascending, click again to sort descending. 1 1995-1996 78.4 0 2 1867-1868 74.8 0 3 1960-1961 73.5 0 4 1872-1873 71.7 1 5 1906-1907 70.2 94 6 2010-2011 68.2 0 7 1977-1978 64.9 0 8 1993-1994 64.5 0 9 1898-1899 63.5 4 - 1866-1867 63.5 0 10 1851-1852 63.3 0 11 2013-2014 61.1 0 12 1853-1854 60.8 31 13 1919-1920 60.6 30 14 1957-1958 58.3 0 15 1855-1856 57.8 0 16 1922-1923 57.4 154 17 1966-1967 57.3 0 18 1874-1875 56.5 31 19 1915-1916 56.2 31 20 1904-1905 55.1 0 21 2002-2003 53.1 0 22 1892-1893 52.8 34 23 1856-1857 52.0 0 24 1947-1948 51.0 2 25 1862-1863 50.2 0 26 1916-1917 50.1 30 - 1861-1862 50.1 0

This has been a top 5 warmest summer so far for low temperatures across the region at most of our stations. Several stations have made the top 5 for highs including mine. It’s what we get with the dew points near the highest on record for the month of July. If the week 3 forecasts continue to verify warmer than the EPS heading into August, then this could finish as one of the warmest summers on record for low temperatures.

The extensive grassy areas surrounding the Tweed HVN airport have turned brown over the last few weeks. It has been the 8th driest June 1st to July 23rd on record here with under 3.00” of rain. Combine that with the 4th highest average high temperature to enhance the drying. Plus the 98° max during this period here was the 3rd warmest temperature ever recorded here. We have been seeing very little balance with our rainfall patterns. Some areas have had extreme flooding with other areas seeing very little. While we have been in an overall much wetter pattern last 20-25 years, many times we are getting the rainfall all at once rather than spread out.

July 1993 was memorable especially in NJ for the number of stations with an average high temperature of 90° and higher. July 2022 was the most recent version of this in NJ. But July 2010 and 2011 have the most number of stations at 90° and above. This July so far has been more about the record dew points keeping the low temperatures up. So the 90° average highs this month aren’t as impressive as some past years. Monthly Data for July 1993 for New Jersey Click column heading to sort ascending, click again to sort descending.

1995-1996 is still is unsurpassed for wall to wall cold and snow from late November right into early April. Getting 80” to 90” of snow on Long Island was epic. Probably the most perfect balance of long duration sustained cold and great snowstorms. While 2002-2003 was still great, it was an overall weaker reflection of 1995-1996. For short term snowfall intensity combined with short term sustained cold I would rank 12-26-10 to 1-27 -11 the best little over a month winter period with some spots getting 60”. If we could have found a way to sustain that for more than that short period, then we could have beaten 1995-1996. While I am extremely grateful for 2009-2010 to 2017-2018, it would have been nice if we could have surpassed 1995-1996. DC to Philly set their all-time snowiest season in 2009-2010. With Boston putting up their best in 2014-2015. Data for October 1, 1995 through April 30, 1996 Click column heading to sort ascending, click again to sort descending.

That was a great late season higher elevation special. https://www.nytimes.com/1983/04/20/nyregion/spring-snowstorm-disrupts-schools-and-traffic.html WAYNE, N.J., April 19 - Drifts of snow, chilling sleet and heavy rain hit northern New Jersey today, dumping 15 inches of snow at Budd Lake in Morris County and 10 inches in Hackettstown in Warren County. Six inches of snow fell at Gladstone in Somerset County and four inches in Newton in Sussex County, according to the National Weather Service.

Yeah, 1982-1983 was one of my favorite winters for that February 1983 snowstorm. The early model runs were keeping the heaviest snows down closer to Philly. Then it shifted north right before the storm. It was one of the few storms that came in as a wall of heavy snow right from the start. I was in class right before it started and it was just overcast with a dark sky to the south and brighter to the north just before 1pm. Then right as we were getting dismissed closer to 2 it was snowing very heavily. One of my favorite walks home from the LB High school in heavy snow.

While it was a very wet spring and the rain gauge in Central Park was broken, a very strong summer drought develped in the Midwest to the East in 1983. One of the strongest Great Lakes ridges pretty much shut off the sea breeze. So extended westerly flow. If we ever saw this type of pattern from June into September in this much warmer climate, then I would expect 100° heat even to JFK as late as mid-September.

2010 only had 100° heat in July. So 1993 was the last time Newark had 100° heat during all 3 summer months. Last summer Harrison had 100° heat all 3 months away from the sea breeze. So I suppose it’s still possible that somebody away from the sea breeze in NJ could make another run on 100° in August. Especially if the EPS underestimation of the long range temperatures beyond 15 days continues in the East. So the current models could be underestimating the warm up potential beyond the first week of August.
