Dude... second half of May was below normal.   Look up the F6 data.  And crisis mode??   I am barely paying attention.  We have had more than enough sunny days to keep me happy.  Getting into a model debate with the trolls is mostly for entertainment and I was arguing in favor of staying cool.  When we first moved here we had nice summers... 2003-2007.  Then 2008, 2010, and 2011 happened.   And its been nice since.   I don't give 2 sh*ts what the weather was like in the 1990s or 1950s if you want to call that our "normal" summer or if people on here are craving whatever they had when they were kids.  I can go way back and find nice summers in the 1800s and early 1900s.  We all get stuck in nostalgia for many things from our childhood. But climate (like society) is ever evolving with different regimes and longer term cycles.   Nothing stays the same.   And we aren't stuck here.  If nature decides to give us nothing but 1954 summers then we can easily leave.

Nothing says "I'm not in crisis mode" better than forgetting how paragraphs work.

When’s the last time we had a truly warm first half of June? 2019? And that one balanced with a cool second half. 

June 1-15, 2025 was the 10th warmest on record at PDX. 8th warmest at SEA. 

June 1-15, 2023 was the 9th warmest at PDX. 16th warmest at SEA.

Make of that what you will.

You definitely get the worst of the late spring onshore flow regime. I don’t see a single day that looks crappy in Seattle in the 10-day forecast. Rain looks to be timed overnight Friday and Seattle will be mostly shadowed the rest of the time. 

Just replace crappy with troughy.  I am not talking about a specific location.   Its going to be generally cool and frequently cloudy and occasionally showery even in Seattle.   There is a big difference between what is coming up and generally sunny weather in the 70s.

Same. I hope it lasts all month. We need a Juneuary to keep the wildfire threat down. Sorry @SeattleSmokeLayerFan

I hope we at least get solid precip to go along with this Juneuary first half of the month. Worst is when we’re just socked in all day with nothing to show for it, but that is typical June at least here in the foothills.

For clarification... there are some crappy (subjective term of course) days in Seattle too.   And it happens literally every June.  Its totally normal in the big picture.  But you act like every day is the same and beautiful in Seattle while I see some very different types of weather coming up.

This works. Lock it in.

Obvious trend to the warmer solutions. It's coming.

A 4 day "dip" below average is nothing to rave about... Especially after the 3 day spike above average (with larger anomalies) we are currently experiencing.

Even if the second trough doubles down, doesn't look to get below average in that second dip.

Absolutely.   No complaints from me on the ECMWF.   "Juneuary" should be reserved for years when all of June is cold and wet.

No complaints here either. Sun and heat is necessary over the summer months, with as many thunderstorms as possible.

However, once we head into October and November, I expect things to dramatically shift back towards pouring rain, dense fog, thick frost, and heavy snow.

Over/under on number of '54 reduxes it would take to make you leave?

I'm going with .5

I'll take the under. He'd temporarily relocate to Pasco for the second half of summer while his palatial foothill estate hit the market.

77/42 today very nice day. 

[Groundhog]

Our beloved community who loves June troughs would do well in St Johns, Newfoundland. Some snow there today. 

Fun fact: St Johns is the same latitude & elevation as Seattle. 

As much as I love wooly winters—and St Johns gets epic snowfalls and blizzards—regularly having highs in the 30s & 40s into June would drive me squirrelly. 

[KeyPeninsula_Wx]

It’s felt like a fairly benign spring. It’s been on the dry side but also a bit on the warm side but not exceptionally so….
 

It’s felt a lot drier than it really has been since a lot of the rain has fallen on a couple days with lots of 0.00” days and sun mixed in. I’d like a bit more rain but life ain’t perfect.

If I saw snow regularly throughout the winter, I would most certainly not want more snow.

But of course since snow is such a rare treat over here, I'd crave snow any time of the year if I had a chance to experience it. June Gloom doesn't look to hold up into late month so I doubt I'll see any in my Rockies trip in Canada. However, I am hopeful for some stronger storms... If I run into them.

I don't know what to tell you, other than that May isn't supposed to be a wall-to-wall sunfest with July like rain totals. These troughy interludes are totally normal for this time of year. Not to mention that there still has been plenty of sun even with our cooler days, and May finished both warmer and drier than our new 1991-2020 normals.

And, not that I'm in any position to lecture anyone here about "not freaking out", but dude, you genuinely sound really upset. Which is interesting considering this spring has been better than normal for your standards. I don't know how to come to any conclusion other than that the 2013-present warm period has totally skewed your expectations of what to see from April-October.

Interesting climate for sure. An incredible 143” of snow per year and the average highs at least approach 70 in summer. I figured their summers would be more like northern Scotland. Boost the average high by 10F or so during MJJAS and increase the number of sunny days during that time and you’d have my ideal climate.

They have some of the most extreme seasonal lag you'll ever see south of the actual arctic due to being so influenced by the sea ice. Their March average is over 2 degrees colder than their December average and their September average is over 4 degrees warmer than their June average.

I don't even know what I am saying that makes you think I am actually upset.   Its been quite nice since March ended.  I give April and May a B+ this year... and it would be an A- if we didn’t have the snow event in the middle of April.  But the grade must be lowered for that ugliness!  It only rained here on 8 days in May... and with way more sun than usual.   Great month overall.

And now we have a few days of troughing coming up and then what appears to be a really nice warm up which is more than I expect in the middle of June.  Record highs actually dip during the middle week of June.    Troughiness at that time is absolutely climo here and we might be treated to the opposite.

Ever thought about doing some modeling?

I know a member in an another weather forum that lives in Prince Edward Island. Now it's June and there are barely any leaves on the trees there. And they started the first day of summer with a subfreezing low.

Oh my God I can't imagine how bad of a climate PEI is.

Pretty massive Polar Vortex tracking across the Arctic circle to north of Alaska over the next 12 days.

Why thank you but...that's not my hand.

Thinking I might need to take tomorrow off before winter returns. 

[Meatyorologist]

An 85F+ day is appearing likely tomorrow for most metro areas along the west coast. Seattle's summit thus far in 2026 is 82F, set on 5/12. It's looking likely that we beat that mark.

Then overnight, a very weak, very marginal midlevel threat manifests itself Seattle north, particularly around BLI and Vancouver BC. I wouldn't expect any lightning out of this low capped fluff, but if there is any, it'll most definitely be of the one clap wonder variety, and probably in BC.

The nature of the disturbance involved has been in flux on the models. If it cuts off a touch better as to allow for slightly more negative tilting, the risk for an isolated thunderstorm or two would increase a bit. When living west of the Cascades, where we get seven thunderstorms a year, one has to pay attention to every little risk, no matter how close it is to being a non-event.

[MossMan]

Looks risky! 

[Port Angeles Foothiller]

For my area looks like rain chances have boiled down to Friday and Saturday. Hope it pours.

I would love it if the lows are in the 20s and the highs are in the 100s over the summer here. A crisp east wind (yes, I know it is downslope and it would warm us up...............but).

I thought you liked trees?   That would be catastrophic for most vegetation.   Sort of a tame version of the extremes on Mars.

True, less trees to burn down. I guess most of the summer would be "normal" weather, though we could spare some extreme days.
