Of the 92 days of meteorological summer at SEA... 61 of those days were at or above normal.  And that is using the new warmer averages which were projected to make colder than average days more easy to achieve.

Oh, I know you just referenced SEA, but it’s gonna happen 😆

Which is why I’m glad the last system that went through focused to the south.

SEA finished this summer with an average temp of 66.8 which makes it tied for the 5th warmest summer ever.

2015 - 69.2

2013 - 67.4

2018 - 67.4

2021 - 67.2

2014 / 2017 / 2023 - 66.8

Given that all the years on this list are within the last decade... it might be noted that summers seem to be getting warmer.

2022 comes in right behind 2023 tied for 6th place at 66.7 with 1967 and 2019.  

This summer was actually a little bit warmer than last year.

From a meteorological summer perspective Jun 1 - Aug 31 which was what TT-SEA was referencing last June was fairly chilly (-0.9)so it makes sense not to make that list. It wasn’t until Aug, Sept, Oct that got fairly warm departures.

Summer at SEA...

June  +0.0

July  +1.4

August +2.5

Did not end up being a front-loaded summer as expected.   It was the opposite. 

Average temp at OLM this summer was 64.3. That was basically the same as last summer, and cooler than 2021 or 2014, very close to both 2018 and 2017, easily warmer than 2020, 2019, and 2016...but more than 2 degrees cooler than 2015 and 1958, which are virtually tied as the warmest summers on record.

For OLM, 1958 and 1967 are both top 5 summers still. 1958 tied with 2015 for warmest on record, and 1967 comes in third behind 2021.

So while summers have obviously been unprecedentedly warm, a little bit different picture than SEA.

I feel like this summer hardly even tried and we still scored top 5. If you include May its 3rd hottest. Compare to Eugene for kicks 💀💀💀

Fine first day of meteorological fall out there. Partly cloudy and mild, temp is hanging at 68 after a low of 59. The air smells clean and the landscape looks refreshed from yesterdays rainfall.

Hoping this month offers a reprieve from the constant torching since late April, but I’m sure that will be a tall order.

It’s always bad to bet against torching these days, but the long-term models are actually pretty favourable for us this month.

It's called clown range for a reason.

IDK if you missed my post the other day where I mentioned from January 20-April 20th 82.4% of our days were below average. As JT once said. What goes around comes back around... And we know in this climate it will come back around 2X.

Did not end up being a front-loaded summer as expected.   It was the opposite. 

It was front loaded up in N/W-Canada, though.

Anomaly centers were slightly displaced from the analog consensus but generally speaking it was an old school niño pattern with a few added quirks.

Started seeing 80°F+ highs in February and will likely continue well into October as usual.

My temp default has been “warm” for so long that I’ve forgotten what cool air feels like. Only taste I got was in Seattle in late July.

Pray for Yellowstone. 🙏

At least I’m done with school at the end of the year. Hopefully I’ll find good work and we can find a new place to live before the summer of 2024 rears its ugly head.

Relative to global mean SSTA, the off-equator NPAC is quite cool. Don’t think there will be much +TNH/-EPO this winter..blocking more likely to come from NAO and/or Siberia.

Which heavily tilts the odds towards a stormy winter in the west, especially the southwest given ENSO. But it’ll likely be of the warm, Pineapple Express variety. Very little cold in western Canada to draw from in such a pattern, unless the -NAO is on steroids.

Yeah. It looks pretty nice the next 7-10 days, but it’s pretty much just average to slightly below average weather. Wouldn’t take much for a lot of those forecast highs in the 70s next week to become 80s.

Can’t call for a “dud” winter at this range since even strong ENSO winters have subseasonal variability. Always possible for a cold week imbedded in a sea of torch.

But yes, there should be no shortage of steamy atmospheric rivers. And likely a top-tier blowtorch from the Midwest/N-Plains to the PNW/BC. Maybe into the Northeast US as well, especially in December.
