Supposed to rebound later. We shall see

Hard to believe it's gonna pop back to 80 degrees this afternoon with the clouds and east winds. The temp is down to 72 here now. And tomorrow will be a struggle to make it to 70.

Back to awful dreary cloudy cool weather

 

Who wants this crap

Seems as if a lot of people here are enjoying it. After 3 days of extreme heat, this is a refreshing change. I wouldn't want this cloudy cool weather to last for too long, but I'll take 2 days of this after that insane heat. It was too hot to go running outside the last 3 days, so I'll enjoy running out there today and tomorrow.

I think 1993 and 1999 were in drought patterns too weren't they Chris? We had much drier summers back then.  July 1999 was one of the hottest months I have ever experienced.  July 1993 right up there too.

Yeah, all the lawns in Long Beach during July 1999 turned brown. 1999 to 2002 was the last time that the NYC reservoirs ran low. These days flooding has become more of a concern than drought.

Currently 70, about 30 degrees lower than yesterday at this time.

Midnight high of 82 for today though.

I would think so too but Upton is still going low 80s and partly sunny 

Actually it just changed to cloudy and 80

Today is just the 5th day on record that Central Park has seen the temperature fall into the 60s following a day with an 80° or above minimum temperature. There were 72 days with 80° or above lows.

I think going forward the only realistic way this happens is if we get these June heatwaves. With the warmer planet and warmer water it would be hard to get into the 60s in July following a major heatwave, but in June when the water isn't as warm yet it's more realistic, CAA not so much but still more likely in June rather than July.

Maybe this will cycle back to more 40s-60s type long heatwaves? If not that, maybe a 1993 or 1999 type heatwave (which is still relatively recent), 1999 had two very long super heatwaves and the one extreme heatwave in 1993 really stands out.

 

Those heatwaves were all about severe droughts since it was a much cooler climate era. Just look at how many summers we had back then when even the warmest parts of NJ couldn’t make it to 20 days reaching 90° in a season. We haven’t seen a summer in NJ with under 20 days reaching 90° since 2014. These days the warm spots in NJ seldom get under 30 days even during our cooler summers.

The GEMLAM is broken. Even at 6z it showed temps of near 90 in Queens and Nassau at 2PM!

Meanwhile we're in the upper 60s to low 70s.

I agree. The SSTs are hugely important. 

% of Lows in the 60s one day after an 80° or above low:

July 15 or Before: 20.0% (4 out of 20 days)
After July 15: 1.9% (1 out of 52 days)
July 20 or Later: 0.0% (0 out of 44 days)

one of the great myths of all time "you can catch a cold from the change in weather"  Nope you need to be exposed to a virus.

unfortunately it also means less extremely hot days so our climate is becoming compressed to higher mins and less high temperatures of 95/100 or more.  1949 must have had lower low temperatures to balance out the 8 high temperatures of 100+ at EWR and 5 high temperatures of 99+ at NYC.

it depends on how it's communicated.  If a change in the weather exposes a weak immune system then it's possible.  Generally speaking, viral infections are more contagious in cold and dry weather because virus particles stay in the air longer.  Conversely bacterial infections are more common in the summer because bacteria love warm and humid weather.

I'm confused I thought he loved cold weather lol.

I like short heatwaves with breaks in between of weather like we have now.

I think it has happened in August before, though I don't remember what year-- maybe 1993?

2002 wow and that was a really hot summer (hot and dry, which we need to get extremes like this.)

a characteristic of summers like 1999 was that we would have weeks without any frontal passages (this also happened in 1993) and then the drought would be broken with a tropical deluge in September after the peak of the heat had already passed. I remember 1991 was also like this, but the tropical system that broke the drought was Hurricane Bob in late August.  We did have a couple more 90 degree days after that in September though.

Yes a few days of this is pretty nice.  4 days of this and 3 days of the other is an interesting roller coaster lol.

we need a 2002 type pattern to have this happen more often.

68 earlier, 72 now. Midnight high of 81

all three summer months were below average and july had a low in the 50s

Looks like a mostly pleasant summer outside of a 5-day heatwave in late August, which, to be honest, was probably urban heat island related anyways. Isn't that the usual explanation for heat extremes these days? Certainly, seems suspect that the Central Park readings went from among the highest in the CWA to among the lowest in the recent heat wave.

In 1948, the first 24 days of August, prior to the heat wave, were pleasantly cool. The mean temperature for that stretch being 72.5F, which has been surpassed on the cool side only three times since (1962, 1992, and 2000).  The average high temperature, a chilly 79.2F. High temperatures that have only been seen once for that period since (2000). A true summer of yesteryear.

1949 had record August cold despite the 100° days. So in those days, the heat tended to get balanced out with cold. Plus the following 1950 summer was the 6th coldest on record.

Rained last night, dropped to 76 last night then the temp rose to a high of 81 around 4am which is unheard of. Having temps rise above 80 at night only to drop into the 60s in the 70s during the day in late June is pretty impressive

Very interesting. If you look at the U.S. national temperature records, 1950 was the coldest year overall since 1929, culminating in all-time record cold and snowfall in late November. But 1951 was even colder, reaching temperatures that have been surpassed on the cool side only twice since (1978 & 1979). The winter of 1950-1951 remains the snowiest on record at Pittsburgh. I wonder if the massive Chinchaga firestorm in British Columbia played a role in that impressive national cool spell. You should look at "Black Sunday" in September. Temperatures in the 40s and pitch blackness. We really hadn't seen anything like that again until 2023. Fortunately, it's looking like the Canadian smoke situation has tampered down for the time being, so, hopefully, that won't have a big impact on temperatures the rest of this summer.
