100 Degree Or Higher Heat Signal For Our Area This Week

[SACRUS]

This last heatwave was certainly impressive but New York City has only hit 90 14 times this summer. That certainly is not impressive when the record is 39. Nonetheless its still amazing to see 100 -105 readings 3 days in a row.

Yeah its up there with the 93, 2001 and 66.

[SACRUS]

The record is tainted because we all know last year should have had the record. If we go by LGA, they had 48 90 degree days last year.

The most for July is 20 from 1993. Unless LGA had more than that last July?

The EWR records are off the charts-- they may have had more than 60 90 degree days last year.

Yes, and NYC should have had close to LGA numbers if they didnt have 3x as many 89 degree foliage affected days than anyone else lol. NYC had half as many 90 degree days as JFK in June, which is pretty crazy. Did EWR miss their July 90 degree number by one? I seem to remember that they had 22 in July 1993.

If I remember correctly, the old record was 49 at EWR from 1991 and PHL still has their record of 59 from the same year, unless they broke that more recently?

2010 .... I dont think it was hot here in 2001. Not my area anyway lol.

2002 was hot.

2002 was hot.

Yup 2002 was my favorite spring-summer of the decade until 2010.

Absolutely, the park was far behind and has been of late. Now thats its dry their more in line with surrounding areas. This heatwave was on par with the great ones from 93, 2001, 66, etc.

Yes, and there are some indications August may be hot also (pos AO), which might be a good signal for a cold winter also.

I do think last summer was a lot like 1966 while so far this summer has been like 1977. I would take either winter that followed

[SACRUS]

This has been my second favorite summer so far, right behind last year's.... I put this ahead of 1991, 1993, 1995, 1999, 2002-- because of the extreme nature of the heat we've had. If last summer was the summer version of 1995-1996, this is the summer version of 2002-03 !

June underperformed but we're making up quick. I still put 2010, 93, 88, 66, 91, 2002 ahead (so far). This is more in line with 77, 83, 99 (so far)

I am certainly in the leaning warm August camp, if not anything else but persistence of the trough into the west and ridging ballooning east.

[Isotherm]

93F high here today.

Newark's basically double my 90 degree days as is Philly. I've got 12 thus far, as usual a lot of mid/upper 80s in the record books. Last summer I was similar to Central Park in that I recorded at least 12-14 88-89 degree days, so my grand total finished at 38.

Yeah in terms of consecutive days, it's very difficult to get more than 1-2 nights of 80+ in a row. I had 2 here which is the first time I remember that happening.

That seems to be the case with Trenton this year, many 89 degree days just missing. They have the biggest contrast to last year.

July 22nd had the highest mean on record...94...old record 93...last set in 1995 I think...

Friday was the summertime equivalent of the January 1996 blizzard.

Yeah basically, I wish I could've gotten a bit higher, like 103 or 104. But I guess 101 will have to do, maybe another run at it this week.

18z gfs came in warmer after the 12z tempered the heat for next weekend. Overall the run is warm and dry into the first week of August,

[nzucker]

Yup, Nate is already dropping his jaw at the 18z GFS lol.

Looking super warm on Fri:

[A-L-E-X]

Nate will like the + AO August correlated to a -AO winter that Tip came up with though.

[JBG]

It's also interesting that Newark was only 103 on 7/10/36 and most places' record highs from that year are from 7/9, not 7/10. Newark in fact has record highs for both those dates from 1993 at 104 and 105.

I have my doubts about the measurements from that era. I suspect that Newark's readings have risen over the years and KNYC dropped. KEWR has, since the 1930's, had the New Jersey Turnpike and I-78 built around them. The airport itself has expanded exponentially.

By contrast, Central Park was commissioned and built under the guidance of Frederick Law Olmstedt in the 1870's. It's vegetation has only gotten denser over the years. Thus, I suspect that 1936's readings would have been opposite, i.e. KEWR's higher, if current conditions existed then, and KNYC lower.

[famartin]

That seems to be the case with Trenton this year, many 89 degree days just missing. They have the biggest contrast to last year.

TTN ran cool in June, maybe from the rain they got compared to PHL. For the most part, however, TTN seems to be getting warmer compared to some other sites... I posted this in the Philly obs thread last night:

[JBG]

That was the end of most heat for that Summer as the whole pattern flipped.

Frankly that week was a major exception to the overall cool pattern of the summer. A lot like 1969 where the last 3 days of May and last three days of June, and the third week of July were the brief exceptions to a dreary summer. Ditto 1972, 1992 and 2009 where week or so periods relieved otherwise dreary summers.

Oh that was the summer of the Son of Sam and Billy and George fights also......

That summer was close to the nadir of both the U.S. and New York City.

[JBG]

And we were in a two year weak el nino and the following winter was absolutely amazing. How many total 90 degree days did NYC have in 1977? Any info would be appreciated, as Im working under the premise that these spike in 11 year cycles.

The way that 1977 complies with the 11 year rule is that each such 11 year summer has at least some very hot aspects. 1977, because it was at the time of the Great Pacific Shift is somewhat an exception to the 11 year rule, unless you, properly, vary it to be "at least X days over 90 and/or 2 days over 100".

Yeah, frankly if it hits 100+ three times in a summer I dont care if the rest of the summer is subzero-- that summer is historic in my book (for the heat lol). That's what we remember the most, not a bunch of days with lows in the 70s..... the fascination with high mins is something Ive never had, since a) I dont care what the temp is at 5 am and they are tainted by UHI anyway. I love a nice combo of 90 degree highs and a few peaks in the 100+ range.

So let's say a repeat of what happened in 1936 happened this summer-- Im not sure it would have been as hot as Friday was. EWR 108? Doubtful, NYC 104? Perhaps....
