This doesn’t make any sense. The whole region is warming relative to their climo. It’s not like there’s a line of warming climate that is moving northward through Oregon and hasn’t reached Seattle yet. The warming is fairly uniform regardless of latitude. Look at what western Canada saw this summer.

Agreed. The dry is more noticeable here than the heat. The dry brings smoke, which I don’t ever recall prior to the last ten years or so.

I am sure the GFS is too warm for today... but shows quite the crash by tomorrow.    Then all the models seem to show a slow and steady warm up.   Very little rain in sight now... although the mountains and foothills will get some tomorrow and Monday.

What areas of King/Pierce County would you consider Foothills?

Areas east of highway 18 is probably a good defining line. Enumclaw, Black Diamond, Ravensdale, Maple Valley, North Bend, Snoqualmie, Duvall etc.

I've always considered it to be East of this line where overall most these locations are 500ft and over except for some Foothill valleys like Orting, lower Issaquah and I'm sure many other locations East of that line that's under 500ft but have surrounding hills 500ft or higher. Here in Pierce County Graham, Orting, Kapowsin, Eatonville, Bonney Lake etc... Are examples of what I have considered foothills out here

Yea makes sense. All of those areas are mostly 500+ feet and gradually rise up till you hit the front range of the Cascades. I was only using Highway 18 as a defining road for reference.

Kinda lines up I guess with the EPSL zone from NWS. Not sure what they don't say foothills.

Definitely, that makes sense for places closer to the sound. Some natural AC there, but no way to get around the lengthening dry seasons. The change in climate is definitely a regional/global thing, and it’s kind of impossible to say if one part of the region is getting it worse than others. It’s all relative to climo.

Eugene's avg temperature of 72.5 for August probably would have been a bit higher if not for the smoke anomalies. But I suppose the smoke is going to be the norm going forward. And that sucks

 

Did they beat 1967?

ECMWF has been trending warmer for tomorrow and now shows mid 70s but still shows a decent marine push tonight... low clouds are more persistent on Monday but does show some afternoon breaks and a little clearing.

From the best I can tell, Aug 2023 was Eugene's all time warmest month in terms of avg temperature at 72.5. 2nd place was 71.5 from Aug 2022. I could also be wrong as I've had a couple of drinks.

August 1967 was warmer than August 2022. August 2023 was EUG's warmest month on record, and August 1967 comes in second. July 2015 is third, barely beating out August 2022.

While your point is true, it's also fair to acknowledge that the warmth has been more pronounced further south recently.

EUG has set 8 record warm months since 2014. OLM has seen 4.

Yep. I corrected it a few minutes ago. July 2015 and August 2022 both show 71.5 on ACIS, so I have no idea which one is higher. I'm guessing you are getting your info in a much better method than that. Can you provide me a linky?

Looks like Portland's all time record warmest month was set in July. 75.4 degrees. They also set their all time record August at 72.5 degrees. Holy shiznit this is getting ridiculous.   

Not sure where you're getting your stats from...PDX's all-time record warm July is 1985. They did set their record warm August this summer.

If you look at the more rural stations nearby though, the picture is not quite as "ridiculous".

Battle Ground, for example, did not see a record warm August. Theirs is still 1967. They also have not seen a record warm July in recent years. They did see a record warm June in 2021. But all in all, they've seen significantly fewer record warm months than PDX in the last 10 years.

Think you’re mixing up the numbers for July and August. But yeah it’s still unsettling. Beats a 1993 crummer 🤮 redux tho!?!1!!

Sure seems that rapid warmth has been…working its way north.

Yep. I'm gonna step away from the temp stats for now. I was looking on ACIS and mixed up the months.

Speaking of EUG...pretty crazy how they went from an unprecedented run without any real "cool" days (no sub-80s from 7/11-8/26) to now seeing 5 of the last 6 days since that streak ended fail to reach 80 - and two failed to hit 70.

They're supposed to hit 80+ today, but that is looking unlikely. And then there's a good chance they see 3-4 more sub-80 days starting tomorrow.

Yes. I noticed I was incorrect previously. 1967 was the previous record of 72.0. 71.5 from last August was also achieved on 2 occasions.

We'll almost certainly see 80 today as the clouds/potential rain hasn't materialized for the most part. Already 77. But yes, the chilly air the last few days has been thoroughly enjoyable.

Ah, the NWS page was showing 66 still for EUG, I see on the actual obs they're up to 75 as of the official noon update.

The rain event a couple days ago really seems to have put a damper on the fires. Not a ton of rain showing up on the models but still can’t complain too much about where we’re at now after the recent rain.
