Ah, you choose to go SUPER regional when it fits your point.

As you well know, my points about last summer pertained to the lowlands of the western PNW...you know, Seattle, Portland, etc. That climate region. 

Here's where the summer ranked for the major westside stations. As you can see, most were not close to 4th warmest.

BLI: 12th

SEA: 14th

OLM: 11th

PDX: 7th

SLE: 6th

EUG: 3rd

 

 

So 2025 actually was meaningfully cool compared to other recent summers in the region? Interesting hill to die on.

And 7th, 6th, and 3rd place finishes are not "close" to 4th?

And definitely less true elsewhere in the region. To Dare Duck's point earlier, in no way is SEA singularly representative of the region, and in this spring's case it's pretty obvious that it is not accurate to characterize it as "average" for the region for temperatures under any context. It was another warm to very warm season.

For PDX, it was the 5th warmest spring on record (since 1941). It came in +1.4 on the regression line and +2.1 on the 30 year moving average. 

Fairly similar story for OLM, SLE, EUG, MFR, GEG, YKM, PDT, RDM etc. though the rankings obviously depend somewhat on the length of the period of record.

 

It was 13th warmest for OLM.

86/45 out here so far today. Hottest day of the year so far and first day to top 85. Last year we hit 90 in the first week of May. 

[KeyPeninsula_Wx]

Models seem to agree on generally 0.25” or so for most people in Puget sound outside of the c-zone…not really too crazy. Who knows about the stuff next week…but my guess is it won’t be too crazy either. 

[Cold Snap]

Almost a 90 burger here with a high of 88. Currently 86.

[Eugene-5SW]

Really no ensemble support for the rainy GFS operational, but at least most of the heatwave consensus is being pushed further out with each run.

[KeyPeninsula_Wx]

FWIW the 18z euro is a bit wetter and more in the 0.5-0.75” range for Puget sound but it really does seem to have a “wet bias” sometimes. 

[SeattleSmokeLayerFan]

Only a high of 87 here but nearby stations have hit 90 to my north in the Renton hills.

Despite being so hot... It doesn't feel hot. 90s and 100s need to come sooner.

[MossMan]

Does tomorrow still look mostly dry? Probably should have mowed today but the lake forced me to stay most of the day. 

[MossMan]

More views from today…A 747 from Mexico City to Anchorage, and a typical lake mystery that I see on most lakes. Abandoned looking cabin but a newer dock…I so want to know the backstory with some of these places.

Seattle has a way of being on an island of lower departures, if you will. Maybe Seattle being the first American PNW city to really blow up in population allowed for an earlier onset of UHI influence to compare modern records to. Maybe our position well north of central and southern Oregon has fended off the worst of the northward shifting 4CH influence. Or maybe it's the airport's tendency to draw in a north wind off the sound on hot days with a stronger inland pressure gradient; a weather condition which has seen a surge in prevelance proportional to the summer warming trends we've seen in modern times.

[KeyPeninsula_Wx]

Ended up touching 87…looks like onshore flow is starting to trickle in though. 

[DareDuck]

After 9 1/2 years, my steak of skiing at least one day every month came to end because of my knee injury. I should be walking crutches free in the next 10 days or so. Dont think I’ll be able to hike to an area with snow. I still stepped on snow last month so I still have that streak dating back to Aug 2016.

The presence of the Sound also just keeps things a little more grounded around there. Being a much more maritime climate than areas immediately further south and east has a way of softening any warming signal just a bit, and diluting some of the outsized departures and ranges that more continental locations are capable of. And yeah, SEA in particular has had more erratic changes within their POR due to at times rapid development and subsequent sensor updates they seem to have made there. 

You can head due east at the same latitude out to the very rural and more continental Cedar Lake station (aka Timland) and find that they pretty consistently run warmer departures in the warm season than the Sound influenced boglands do. For those more transitionally continental spots like the Cascade foothills and the Willamette Valley, having just a smidge less marine influence in the summers now goes a longer way in terms of amplifying the warming signal to an extent.

Already down to 76 here.  

[Phishy Wx]

only got to 70 here

[Phishy Wx]

perpetual spring continues....

How long is TT-SEA's streak of NOT skiing? I wonder

Nice sunset last night.

53/85 here. Down to 83 now. No wind here yet so still feeling toasty.

My 2024 knee injury effectively ended my skiing days.

Surprising underperformance today by everyone's fav station, PDX.

I have approximately 5 billion seeds, although I’m sure @Doom Buster will fact check me.

We gotta wait on an official count from our forum fact checker.

Too bad all those doomers UNDERPLAYING the supply of seeds left in the world. We have TRILLIONS of seeds left, but of course the climate change alarmists need to pretend we ONLY have 5 billion left. 

Then @Anti Marine Layer might need to chip in about how "'they" are trying to justify government-controlled artificial plant-based lupines and cloud seeding facilities.

You’re clearly not up to date on the latest literature. 

Uhh, it is an obvious and demonstrable wavenumber-8 pattern. I can post the NCAR reanalysis of NH heights and streamfunction if you want?

And such patterns have known triggers, both for wave stations and amplification. You *can* argue that augmented WPAC/warm pool convection in recent decades may increase the frequency of said patterns (which have always been vulnerable to the modes of resonance that can lead to extreme amplification in some cases).

However, the extremely anomalous nature of the June 2021 event cannot be tied to any similarly anomalous atmospheric river or source of latent heat release (such as a TC). In fact the modes of forcing most favorable to produce standard +TNH/+PNA (loading pattern for the 2021 event) were only transiently present beforehand.

It was a black swan event, a cascade of perfectly timed ET wave cycles under exactly the correct in-situ z-cell+tropical forcing state and exactly the right evolution of said forcing state, at exactly the right time in the wave cycles, at exactly the right time of year to both maximize the wavetrain response *and* to maximize insolation/surface heating at the more local level.

I don’t think people realize how exceptional that event was. More statistically anomalous than any other large scale weather event in US history.

[StormchaserChuck1]

^March 2026 in Flagstaff probably beat it. It had never gotten above 73 there in March before, never ever reaching 100 at any time of the year, and they hit 86. Someone did an odds analysis that said 1:10,000 years, although it's probably higher and more likely to happen if the mountains don't have snow on them like this Winter.

The low amplitude ridge which was pinched off into what is known today as the June 2021 heatwave, was strengthened and preceded by a stout, highly anomalous atmospheric river. KSEA saw nearly 2" of rain in 36 hours with highs in the 50's. It's actually funny that you missed this fact, considering the heatwave was one of the most well documented and well researched weather events in history.

That was a standard jet extension and not even close to record breaking in terms of PWATs or U-wind.

No one is saying there wasn’t an atmospheric river beforehand. But said atmospheric river does nothing to explain the exceptionally anomalous pattern progression thereafter.

The “pinching off” you refer is a textbook element of the process I was referring to earlier (trapping of the wavenumber 8 pattern).

Could've been hotter in some places if downslope winds continued on into the afternoon.

@the_convergence_zone

I highly recommend you give this a read.

This study precisely predicted the possibility of these extreme summertime wave amplification events nearly a decade before the June 2021 event made it popular. And it is correct.

Of course now everyone jumps in and attributes such events to their own pet theories, most of which they’ve *coincidentally* staked their reputations on across years/decades.

Tomorrow morning is my big interview, hopefully it leads to a “let’s hire Fred”. A preemptive thank you for your collective thoughts, prayers, and meditative moments of manifestation.

Cooling off nicely down to 74.

Seems like a lot of people on here are interviewing or starting new jobs. Today was my second day at my new job. Hope it goes well it is rough out there in every field. 

[MossMan]

The best part of today (I should have somehow taken a video) at the lake was the old guy (at least 80yrs old) wearing suspenders pulling up to the public dock in his fishing boat…Blasting Metallica’s Master of Puppets album!

What happened to the water treatment job? That was one of the more interesting gigs on here.
