August 2025 Summer Thread

[Cyclone-68]

Per the point and click it looks like they backed off on the mid 90’s for next week?

The sun has lacked bite over the past week from the smoke. It almost feels like a week long partial solar eclipse. 

I was trying to think of a way to describe what its been like and that is about as accurate a description as any I could think of.

Feels terrible to ask this and there are going to be some great responses.... what's COC?

it's a reference to summer weather conditions that are characterized by warm (not hot) temps and low to moderate humidity (dew points less than 60)

Meanwhile Columbia, South Carolina has been below 80 since August 1st...

Actually got to 57 this morning. Lowest was 56.4 last weekend so definitely notable. Luckily that’s gone now.

Might be some 40s tonight in CT

I feel like it will be warmer tonight?  Maybe similar to last night. There were 40s here in ern areas last night.

It’s abbreviated for Chamber of Commerce. There are certain individuals who think smoke filled skies, lung hacking, and sweatshirts in the middle of summer as Chamber of Commerce. 
It’s silly because our summers are basically the Mid Atlantic now so Chamber Of Commerce or COC is really bathing suites, jet skis, and a rum punch in hand. 

Hype day 3 no smoke COC

Yeah

Serious post for a change.  As we head into a heat wave. This is an impressive start for August even on the coast like Bos but inland as well IJD.

I think it's interesting because that occurred with either nominal actual negative, or positive anomalies in the 500 mb heights.

I'm thinking there was some environmental feed backs that synergistically aided cooler profiles to a realization.   There may have been an initial push of cooler total/deep layer troposphere ending the heat wave at the tale end of July. Whatever the source ... it left, but also left a sloped soundings very left of potential aloft.  Then, given our geography tending to abuse cold displacement south.   If we stack synoptic denser air around the corner of White mountains... it tends not to stop until the Va Capes... I remember a lot of this cooling did come from a slow press S, and then it tipjped SW.  A N-door front for us became a BD for the M/A... 

Then, we slabbed smoke over top during 4 of those days. I'm very suspect that it dimmed the ability to force solar modulation per the course. Yet another factor ... the high pressure moves more E than S, which keeps winds light and none mixing, as well as oceanic contribution (although the flow's been admittedly very light in this latter regard) 

It's been a hodge-podge of physical feed-backs teaming up. 

Just in principle, it's a bit incongruous to get this kind of persisting negative low level temperature result, when under heights persistently above 582 and even approaching 590 at times.  Even the thickness' were above 560 per the course.  We've observed temperatures close to 90 at 564 dm thickness.  yet days pinned in the 70s.   So these metrics demo that this was a bit of an unusual occurrence.  

Not signifying or implicating anything other than the objective observation of these field metrics vs results.    

[Typhoon Tip]

So... being in a 'cool synergistic cage' for a week or more, it starts to get hard to visualize getting out of said cage.  It kind of conditions the mind into thinking it won't get hot next week some how, some way.  Not the most scientific approach of course, no, but there's something to that.

It's a similar phenomenon to being in the 5th inning in the 2002 ALCS, with Pedro Martinez on the mound, with the Red Sox leading the Yankees 5-2 at the time ... and just knowing for some creepy reason that the Red Sox season was over.  It was more than Grady Little's ambling out to the mound to tuck his tail between his legs when Pedro's ego told him go back.  Annnnnd summarily the Yankees scored the two guys that were on base and the rest was history...

It's not analogous as a comparison, per se, but just the 6th sense of it.  Yet, I kind of would like one last heat departure before putting the ballast of summer in the books  (watch us get a heat wave on Sept 10-13th or something...), and committing to missed hurricane season and an early frost/snow in October that heralds in another CC-denied winter shit show. weeee

If the flow is more SE-S then highest temps are rt 2 on north. I still suspect 90-95 for most of the region for several days at least.

Looks like Blue Hill was a top 10 July for warmth. Also one of the more humid months recorded.

This has been an impressive stretch. Got down to 53° here last night.

Need something to develop before it can become a threat. A fair amount of wasted potential in an increasingly favorable TC genesis environment so far this month. 

But next week should be a whole different ballgame with a more favorable environment for the latest wave.

There is still a bit of work to go before we can even begin to think about the tropics heating up. We'll start seeing storms form more consistently, only because we're headed towards peak climo but there is alot of work to be done if we're going to see a significant uptick. Unless of course every wave that lasts like 7 hours gets named.

AI is stupid.  I was looking for something that would easily break when filled with gas and thrown at yellow jackets . Not a lecture for Christ's sake.

There's been memes ( unverified by myself but they're out there - ) that advertized a DP record June and July for the OV-NE/MA regions.   Again... not sure of the veracity of that, but I was entertaining the notion that this may have robbed some of the kinetic temperatures from getting to the higher levels.   

See ( you know this - ) the problem with living around the taint of the continent as we do, we are are the end result of gathered bio farts, industrial air waste, and whatever ozone we can possibly imagine, homogenized with soil moisture and the Great Lakes and the Gulf/lower M/A inflow...  It's really a problem for us to soar the T side of the T/TD in a longer terms sense of climate because of these mitigators. 

This is part and parcel in why the hard empirical data over the last 20 years have shown more of the warm climate via the nocturnal temperature contribution to the means.   These same mitigation in the top side, holds the bottom side elevated.    Not all the time - duh... we're just talking tendencies. But the nighttime lows is where we "swelter"

Anyway, in truly assessing the summer departures, I think the thermodynamics of the air mass should really be evaluated.  I've often mused to self that similar to the OHC, there should be codified AHC ... or Atmospheric heat content, which is derived from the thickness ( not just height)-related potential surface temperature, then aggregated over time.   interesting

Does it really matter what the population is and who lives where? I mean that has absolutely zero to do with the science behind what drives the weather. Not too mention there are also mesoscale and microscale processes which can heavily influence weather locally, but they don't take precedent on the overall synoptic pattern. If its a hot pattern but cool along the coast because of a sea-breeze...it's still a hot pattern. If it's a cold pattern but temperatures are moderated along the coast it's still a cold pattern.

Good post, Tip. I expect Massachusetts to finish around 73.7F for the month (+/- 0.3F). Very crowded field. That figure would place them in ninth, but just an extra tenth would move 2025 instead to a 4-way tie for 6th. There seems to have been a reversal from the era of the 2010s where ASOS sites like Logan often ranked higher than state-wide averages. Now, the warmth is being driven more by coop sites. Blue Hill Observatory in Milton, Mass. notched is 4th hottest July on record.

Looks like maybe there's been some amelioration of the urban heat island effect, perhaps by having created a more effective atmospheric blanket over the smaller towns and rural locations, thereby negating the conditions that drove the unbelievable radiational conditions some of these areas used to experience?

Nailed it! Very weird pattern with urban/ASOS sites tending to run below the statewide rankings in a sharp departure from recent years/decades where they've tended to run higher. They make up a sizable amount of the nClimDiv stations too, so the warmth was even more impressive at the co-op sites to bring the average up to 9th place.

Even the most objectively attempted science is still born of humanity; thus, humanity makes the science less than ideally objective. 

I agree ... a blizzard of 30" and 100 mph wind gusts happened whether there is a human there to complain about it or not.  Like wise, what if it were 133 F routinely out there in the ambience of the world, yet no one happened to have ever felt it - global warming might truly, truly be denied.  

Fact of the matter is, the 100% objective analysis and conclusion pathway needs to be "weather" anything happens at all.  Not whether someone was around to hear the tree fall in the forest.

It's 630' so much closer to the elevation of the population around metro BOS and away from marine taint. It's also the most pristine record taking stations in the country.

Agree about "significant uptick" but the subseasonal environment is getting more favorable. And if you're the kind of person looking for land impacts you probably want only one game in town--or at least widely spaced systems--otherwise you'll likely end up with ridging weaknesses all over for easy recurves. My current thought is that 96L underperforming may actually open the door for a closer approach of the follow up wave because the weakness in the ridging that is going to take 96L away will have the ability to close before the wave leaving Africa can reach it.

Hmm...KGON seems to be having some sensor problems.  Hit 91 yesterday and 93 already today.

No smoke, no humidity. Just a 10/10 day out there.

Blue Hill Co-op saw its 4th hottest July on record with a mean temperature of 75.4F. Overall, it was the 9th hottest July for the state of Massachusetts with a gridded mean of 73.7F.

Not sure if the Coop is the same as the observatory. I read it off their website.

Yes, you are right. Looks like the NWS must have a coop site nearby too. Looks a little warmer throughout the record than the observatory numbers, maybe lower in elevation?
