Strongest La Niña trade winds on record from late June into July.

The bottom line is that the tree growth since the 1990s has probably cost NYC at least 13 days a year reaching 90°. This is by the more conservative Newark figures. Faster warming along the lines of LGA would yield more than that number. So the Con Ed customers should probably be asking why their summer cooling bills aren’t going down like the Central Park 90° days? NYC 90° day drop from 19 in the early 1960s to 16 in the early 2020s..should be 29 using more conservative Newark 90° day increase -3 Newark 21 days to 31 days….+10 LGA 10 days to 25 days…+15

This may have tied the 2nd longest heatwave on record in New Jersey at 14 days for Hillsborough-Duke. The heatwave included 4 days in the 100° to 102° range there. Newark had a heatwave which lasted 20 days in 1988. So this 14 day streak would tie the 2nd longest at Newark in 2010. Atlantic City had a 14 day heatwave in 1995.

This may be the first time that our area had multiple days of 100° heat with a trough over the Upper Midwest and Great Lakes. The 10 event 100° day composite from 2010 to 2021 featured a strong ridge over the Northeast instead. So the steadily warming summer climate is finding new 500mb patterns to deliver extended 100° heat into our area. Recent extended 100° heat 2010 to 2021 composite of 10 days reaching 100°+

The tree growth covering the Central Park ASOS has made its highest temperatures closer to Suffolk County than the rest of our urbanized areas since 2013. Central Park hasn’t reached 99° since the 2013 summer. Islip has come closer to 100 than NYC over these years. The list below is our highest summer temperatures since 2013. The multiple 100° days at the NYC micronet stations aren’t on this list since it’s on a separate network. So this is the 2nd longest streak below 99° in NYC since 1873.

The network that I used doesn’t cover the NYC micronet and the NJ mesonet . So we have to use micronet sources for the 5 boroughs of NYC. Several of the COOPs around NYC in 1977 closed. There were multiple 100° days in the 5 boroughs during this heatwave. https://www2.nysmesonet.org/networks/nyc 7-20 Brownsville 100° Corona 100° Tremont 102° 7-22 Brownsville 100° Corona 100° Tremont 100° 7-23 Brownsville 101° Corona 100° South Ozone Park 100° Tremont 101° 7-24 Corona 101° Fresh Kills 100° Tremont 101°

We had a mix of days this heatwave with lighter and stronger winds. But NYC temperatures were in line with the South Shore sea breeze sites from JFK to ISP. So the high temperature cool bias has been pretty consistent across multiple patterns. I can still remember the old heatwaves like July 1977 when Central Park was one of the warmest sites. There are many more examples like the one below between recent years and before the mid to late 90s.

The EPS has a break in the record heat over the next week. Still generally warmer than average as the cool departures stay to our west. Not much improvement for the locations experiencing drought. Then the heat builds east from the Plains in early August again. Jul 25 to Aug 1 Aug 1 to Aug 8

We can clearly identify the mid 1990s into the early 2000s as the period when the trees began to cover the Central Park equipment. From the 1950s through the early 1990s, NYC would record 90 degree days in reasonable agreement with either EWR or LGA. Then NYC fell far behind during the 2000s when tree growth caused the high temperature readings to become unreliable.

But the tree growth over the equipment has prevented it from happening since 1980.

I added the NJ July highest temperatures below since 2010. Newark and Harrison are often close on the max like the 102° this July so far. One of those stations is usually the NJ leader. New Brunswick is usually several degrees cooler since it’s more of a suburban setting than Newark and Harrison. Much of the July variance from year to year in NJ is probably the result of differing prevailing wind patterns. The Newark site is right near the bay. So active bay breeze years like 2021 will allow Newark to run cooler than surrounding sites. The 2010 Newark disparity is a result of the thermometer malfunction at around 12:30 causing the station to miss the local highs of 106-107 a few hours later.

They should probably read the paper that I posted yesterday on how flawed the MADIS comparisons are. While the OKX crew does a great job on forecasting, what they let happen to the Central Park observing site doesn’t speak highly of the quality control at the NYC ASOS. I don’t think that any other local NWS office would allow that to happen to one of their legacy sites. At least the forecasters from the surrounding offices drop in and add their comments. But we seldom see forecasters from the OKX office comment on Central Park.

Who is throwing out New Brunswick? The point is that the 100° heat wasn’t isolated to Newark over this current heatwave.

Saying this person said x on y board doesn’t help us out. We have the actual data from this heatwave. The 100s were widely recorded from Harrison back to Somerset County.

There have been times before the current heatwave when it seems like there may have been a +0.5 to +1 variance like you have shown. But over the last few weeks, Newark has been really close to the other usual warmest sites. We could probably make a case that the variance between Newark and other warm spots back in June was wider than usual. Comparing Newark to New Brunswick can be a challenge since the Rutgers station is much more suburban by comparison. As you mentioned, Harrison has gaps in the data. Plus the Newark climate period is 1991-2020. The temperature record at Harrison only goes back to 2000.

That’s right. The heatwave wasn’t that bad theme was very active on Twitter and other sites this weekend. The dense vegetation growth since the 90s in Central Park seldom gets mentioned. This is really where the NWS needs to step in. There have been numerous posts in recent years on various websites stating that heatwaves in recent years haven’t that bad because NYC was cooler and more reliable. The NYC thermometer wasn’t in the deep shade when many of the older records were set. Record heat this afternoon: from the NY Times: Daily record high temperature, since Central Park 106°F set in Dust Bowl of 1936. Tree growth around the NYC ASOS in recent years Original condition of the site when records like 1936 were set There were several temperatures higher than 106° at our local stations back in 2010 and 2011.

He invalidates his whole premise about the difference between Newark and other stations during this heatwave with this one passage below. In other words, instead of a five day temperature trend of 100-100-100-101-102, it may actually have been as cool as 97-97-97-98-99. No record-breaking streak of triple digit heat. Harrison nearly had 4 days in a row of 100°. So is it so hard to believe that the environment at Newark could be a degree or two warmer on the 21st and 22nd? Temperatures can vary within a few miles. Plus several more rural stations like SMQ just missed 5 days of 100° by 2 degrees on the 21st. Data for HARRISON, NJ Click column heading to sort ascending, click again to sort descending.

Relative to the July rankings, several of our stations are at or near the top for July warmth. While Newark is in the lead, White Plains and Danbury are not far behind. A number of stations in the Mount Holly forecast zones are ranking very high also. We can see how many top ranking years there were since the summers became much warmer in 2010.

The continuing marine heatwave in the NW Atlantic has helped Nantucket reach the warmest July on record so far. This part of the Atlantic is one of the fastest warming in the world.

Sunday had the most 100° readings across the area in a long time. There were at least 11 stations that made it to 100°. Newark, Berkeley Twp, and Somerset County reached 102°. So the addition of these new micronet stations shows that Newark really isn’t that unique. People need to look at more than just the NWS hourly round up of major airports to get a full picture of the climate in our area. So posters on twitter should feel free to join the fuller discussion in this thread rather than issue random tweets that don’t do reflect the actual conditions in our area.
