July 2025 Discussion-OBS - seasonable summer variability

I don't think one night in the upper 30s would do much harm to corn/maize. Obviously, if it was consistently cold (and/or moist) that would affect growth. Consistently warm overnight temperatures are a bigger concern because the plant can respire through the night and burn stored energy faster than it can be replenished. Corn is native to higher latitudes in Mexico. It does best with overnight lows from in the 50s/low 60s.

The reason I said mountaintop is because I've been in the Poconos during the summer and it does get into the 30s there a few nights every summer and it's quite refreshing.  I've never seen it happen in July though, it's happened in the first half of June and the last half of August a bunch of times.

What a difference up here from yesterday, currently 66/63 and breezy as more rain moves in, I have to admit there is an early fall feel out there for now. 

lol it was a sauna here this morning as hot as it was yesterday, but after 1 pm the temperature suddenly dropped from 93 at 1:10 pm to 86 at 1:30 pm and now I hear thunder and it looks like it's raining at Yankee Stadium??

There are a few localized spots that still suck but they are way down from what they used to be and even the spots that still suck are better than what they were. 

Overall NO2 in the atmosphere is way down. And we were talking about rural spots anyway, not the Cross Bronx haha

I feel bad for those people that live near those highways.  There's also a strong link between children who grow up near highways and autism.  It's probably the strongest environmental link there is.

this sounds like 1976-77 lol

Too bad we didn’t have the forum back in 1976. Can you imagine what the speculation of what the winter would have been like after the record cold in late August?

It would have also been great to have social media with everyone posting photos. The amount of ice on the local waterways by late January 1977 was epic. But there aren’t that many photos still available. All I remember from that winter was how cold it was in the mornings waiting at the bus stop.

7 shy of 2010 and 4 from 1993

Yes, 2010 was the only summer I have seen that JFK had 30+ 90 degree days 10+ 95 degree days and 3+ 100 degree days.

NYC did it in 1993 too.  Those were my two favorite summers.

So you lived in Long Beach in 1976-77 and 1977-78? You saw the epic February 1978 blizzard there then!  I always thought the 14" JFK reported was way too low-- it was probably too hard to measure snow accurately with so much wind!

Were the waterways around Long Beach completely frozen in 1976-77? It must have been a shock to the system when JFK recorded their earliest ever 90 degree day in April 1977!!

Yeah, the 1970s were a wild decade living in Long Beach. First, I got flooded out of my basement apartment for a week in 1972 when TS Agnes came ashore with the very heavy rains. Then the December 1974 Nor’easter which flooded the streets with a tidal surge in front of my elementary school.

1976 featured Hurricane Belle in early August when the ocean met the bay in the West End. My friends lived on Gerogia Ave and the tidal surge pushed the ticket booth for the beach passes down the street. Then the record cold at the end of August with 50 around NYC and 30s to the north and west.That was the coldest winter that I ever experienced. It was so cold that I wasn’t able to get down to the local waterways to see how much ice there was. 

Then the January 1978 ice storm which was the worst on the South Shore until January 1994. This was followed by the surprise January 1978 15” snowstorm when heavy rains were forecast. Followed by the epic February 1978 blizzard and snow drifts that the LB city bus got stuck in.

Next on the memorable events list was our coldest 2 week stretch in February 1979 and the PD 1 snowstorm.

The only two major heatwaves in that record cold decade were late August 1973 and mid-July 1977. Outside those two short periods there really wasn’t much need to even turn on the AC much living in Long Beach. Just using a fan was enough most of the time.

1996 and 2010-12 were the two wild weather periods I remember. This stretch personally since Jan 2022 however by far has been the most boring.

did central park hit 90 today i know they were at 89 earlier?

Approaching an inch of rain here, just in the past 40 minutes or so. Still pouring

PD1 had a very sharp cut off didn't it-- how much snow did you get in it? I think we got over a foot but parts of the city got much less.

I wanted to be alive to see the early 70s events, especially that ice storm!  I've never experienced anything like January 1994 ever again do you think that's our rarest type of storm?

July 1977 had the most extreme heatwave this area has ever seen, but how come JFK didn't hit 100? NYC did so three times and even 104 degrees (later tied in July 2011).

Yes, those triple digit temperatures in June have been the most exciting weather we've had in years.

That and that April 2024 earthquake (and the eclipse) and the northern lights last October.

Have about 1.57 in the bucket , was coming down sheet rain large drops.

[donsutherland1]

Temperatures rose above modeled levels today on account of lower-than-expected cloud cover ahead of a slowly advancing front. High temperatures included:

Bridgeport: 87°
Islip: 89° 
New York City-Central Park: 89°
New York City-JFK Airport: 91°
New York City-LaGuardia Airport: 87°
Newark: 91°

Philadelphia (93°) reached 90° or above for a record-tying 21st day this month.

A break in the heat is now imminent. A front will cross the region this evening triggering additional scattered showers and thundershowers. Some of the rain could be heavy.

Behind the front, it will turn cooler for an extended period of time. Generally somewhat cooler than normal conditions will likely persist through the first week of August. There are hints on the long-range guidance that a new round of heat could develop past August 10th.

The ENSO Region 1+2 anomaly was +0.6°C and the Region 3.4 anomaly was -0.2°C for the week centered around July 23. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.48°C and the ENSO Region 3.4 anomaly has averaged 0.00°C. Neutral ENSO conditions will likely continue through the summer.

The SOI was +10.59 today. 

The preliminary Arctic Oscillation (AO) was -0.240 today. 

 

[doncat]

Did sneak in a 90° reading before the deluge... that gives me 15, 90° days for the month... record is 20 days in 2010.

wow Philly has been really hot, how many times has NYC had 20 90 degree readings in a month Don? Only July 1993 and July 1999?

what's the JFK record for 90 degree days in one month Don? It has to be from July 2010?

Only once at Central Park: July 1993 with 20 days. JFK’s record is 13 days from July 2010.

Newsday at the time had a graphic that showed 22" in Long Beach during the February 1978 blizzard.  14" at JFK could be wrong, but is not impossible.

[donsutherland1]

July 2025 ranked among the 10 hottest Julys on record in the greater New York City area:

Monthly Mean Temperatures:

Bridgeport: 78.2° (5th hottest)
Islip: 78.5° (2nd hottest)
New York City-Central Park: 79.5° (tied 14th hottest)
New York City-JFK Airport: 79.9° (2nd hottest)
New York City-LaGuardia Airport: 81.0° (8th hottest)
Newark: 82.1° (5th hottest)

Notes: The 0.4° difference between JFK Airport and Central Park when JFK Airport had a higher mean temperature in July was the largest such difference on record. Adjusting for the trees would have led to a mean temperature near 80.0° in Central Park. That would have tied for 8th hottest.
