This east coast heat wave was not in the same ballpark as what just occurred in Europe. Historically inaccurate to make a real comparison between the two.

Goofus at 246 hours....here is what latest Euro shows for same time.

Have to consider where the cold is and what areas are being melted out. The low hanging fruit that isn't as far north has been melted out over the past few weeks.

I think to me what really stands out is the heat just isn't spread out evenly. And the climates that have seen the most summer warming tended to be fairly similar.

Yeah, strong Ninos almost always deliver at least one 12"+ storm here. Most commonly late Oct-mid Dec and then Mar/Apr.

That's definitely true here in CO. Many of our biggest storms have been early/late in El Nino winters.

Breathing fire, eh? Extreme, unprecedented hyperbole warning!

Another .3" here on Thursday.

Squall line moving south down the Front Range from WY, kinda unusual. Will be interesting to see how far it makes it.

It's interesting that 2 of the 3 areas that have seen the biggest increase in extreme heatwaves, western North America with a focus on BC/the PNW and NW Europe, have pretty similar climates. Traditionally very temperate and mild in both the winter and summer, and similar latitude.

Damn, got hit pretty good here last night. Nearly continuous thunder/lightning for a couple hours, .34" of rain and some hail. Looked like the Littleton area really got slammed. Getting some more light rain this morning, too.

Yep. You chose the hottest one lol, and not the official airport one. Is what it is.

The official high for Paris was 105.6F.

There's kind of a built in assumption in these posts that we don't have the technology to help with these issues. This isn't 1850...both from a global temps perspective or a tech one.

No sh*t. It's also fair to point out that there were far fewer records from the stations with long periods of record. Both things can be true.

Yeah, severe t-storm watch and then couldn't even see any storms from here. Today looks a little less hazy, I think.

Thanks. That is important when comparing this event to historical ones. The big numbers in that graphic are obviously due in part to short period of records. Not to say this event is not significant, it certainly is, but records have to be analyzed based on POR, etc. Context matters.

Correct, I'm just talking about what exactly determines the PDO numbers. You can see it clearly looking back through the years.

I believe the biggest factor for PDO calculations is that pool of water south of the Aleutians and to the north/northwest of Hawaii.

Is the 33 record breakers for stations with 80+ year histories all-time records or monthly records?

I think the main issue with comparing the PDO from 2015 to 2026 is that was a second year Nino, which tend to have +PDO much more established by this point. Since it is a lagged response in part to ENSO. I would be surprised if the PDO is not at least moderately positive by early winter.

Not to downplay the casualties from this event at all, but that's one statistic that's a stretch to tie directly to the record heat. Heatwaves in general do increase drownings, but the evidence does not suggest that they rise in proportion to extreme heat. Heat waves increase the overall risk of unintentional drowning by approximately 17% to 26%, depending on the intensity of the heat wave. This spike is primarily driven by a surge of people seeking relief in unsupervised bodies of water. [1, 2] Key Risk Factors Activity: Swimming and bathing-related drownings see the largest jump, increasing by 28% compared to non-heat wave days. Demographics: People aged 65 and older are the most vulnerable, facing a 36% higher risk, followed by children/teens at 24%, and adults (20–64) at 7%. Gender: Men are disproportionately affected, being 22% more likely to drown during a heat wave compared to a 5% increase for women. [1] Geography & Extremes While risk generally climbs with heat, studies show that during extreme (the highest intensity) heat waves, drowning rates can actually fall slightly (to around a 9% increase), likely because the heat becomes so oppressive that people choose to stay indoors.

Would not say it balanced out that month.

Got slammed again with .39" in less than an hour earlier. Some hail but nothing bigger than marble size.

Got nailed today. Ping pong sized hail and .45" in 30 minutes.
