On days like today I wish I live in Aberdeen 

It was terrible out this way and in Aberdeen today while out doing deliveries, smoke made it to the surface for several hours (although AQI reports didn't show it that much, it was very much noticeable). 

This is the first year since I was like 12 years old that my allergies have been an issue and they have been causing respiratory issues for a month so far, it has not been fun at all and this smoke has just made it worse.

My kids will never know a forested Oregon I the way I did.

Blasting through Beaverton on the way to the coast. 93F and smoky. Yuck

Agree, it’s pretty bad here in Tigard compared to my place in Federal Way. Enjoy the coast !

[High Desert Mat!]

AQI is at 439 but it looks like it’s about to push to my east a bit and hopefully I can get down into the 140ish range the next couple of days. 

[Eugene-5SW]

This is my least favorite pattern when I'm situated in the warmest part of the thermal belt. I can have some of the warmest temperatures in the western lowlands. 78 right now.

At least the AQI is pushing 300 and the GFS has turned sharply warmer with 90s for another 5 days at least. Sigh.

Really starting to notice the longer nights.

It’s the February of summer. We’ve got two weeks of properly high sun angle and summer nights left. After that the shadow ratio races to one while we start to see sub 50° angle days march south from the border.

Oh, and three weeks until Pumpkin Spice and Halloween candy.

Those fires are healthy…

I thought they were supposed to make some progress on them the last few days…

We hit 90 on 10/16/2022. Not holding my smoky breath til november!

[Meatyorologist]

Speaking of the above date... Probably one of the greater heat anomalies at SeaTac airport. Up there with 6/28/21 and 4/18/16

It was horrific. But plenty of smoke. I even saw the flames burning on the mountains from the Eastside.

[NWbyNW]

The smoke has definitely kept our high temps lower.  Everett was projected for 81 today, but we hit only 76F.  Same with the day before, we only hit 75F.  But it is also keeping the HIGH temps contained at night for warm nights.  It is 11:30pm and it's still 66F.

Degradation continues west of the Cascade's.  The good areas are becoming less and less. A lot of yellow has become orange and red.  The footballs are becoming soup. Come Thursday evening though, we will begin to see some onshore push, even if minor.  Spokane continues to improve.

 

Conditions got significantly worse for Western Washington as the bad stuff has floated away from the foothills and is in the lowlands. Lucky for Western Washington, onshore flow will because to weakly filter in Thursday evening pushing back the smoke for the lowlands, especially near the water. It may take awhile longer for the foothills, but it is possible Friday or Saturday we could see clean air again. This of course is not going to help Central Washington and Eastern Washington and conditions will get worse. 

Portland has remained bad all day. Central Oregon such as around Bend and Redmond should improve Thursday, maybe to moderate, but places like Prineville will remain socked in the smoke as will much of the eastern half of the state. Western Oregon east of the Coast Range will begin to clear out a bit from Portland to Salem. The coast will start clearing out.  Southern Oregon will remain bad.

3rd straight TSS (Thick Smoke Shocker) at PDX as they failed to reach the mid 90s! Last 2 days were still good enough though for back to back 90

[TigerWoodsLibido]

This was for yesterday as I forgot to post it. But we hit the burger. Another smoky burger later today maybe.

[SilverFallsAndrew]

AQI is 217 in Eugene right now.

You cannot make burgers without smoke

90% humidity vs 4138 AQI

 

hmmmm

 

lol give me the sauna all D**n day

Worst is some combination of both. PM2.5 at 600 and dews at/above 75°F is the most miserable thing I’ve ever experienced (except for renal colic..still in the hospital BTW ).

I can actually see some blue sky directly above as the smoke is clearing out of the area this morning. Praise Jesus!

Thankfully it’s not close to that for you.

12z AI Euro would be smoketastic. ULL parks over the WA/BC border stoking flames off to the east, then a thermal trough rides up the coast and siphons in the goods to the westside while triggering dry thunderstorms over the high terrain. This summer may be an all timer!

Trip down memory lane: 14 years ago today we drove home after a long weekend excursion to Mt St Helens. First time there. It was during that early August heatwave in ‘12. We tented. And of course there was little shade. I anticipate taking our kids there soon. Our youngest (6 years) would be tepid about an imminent eruption, so we’ll give this another year or two.

45 days left of astronomical summer.

[SilverFallsAndrew]

Getting pretty jazzed about this upcoming Nino. Some local EXPERTS I know are thinking we have a mild dry fall, but the December-February will be very active and progressively colder.

October looks stormy, maybe even windy.

I predict fall will arrive within months.

October 24th, 10 am is the Winter Weather Forecast Confrence if you want some more predictions (including when mine releases).

I admire the courage it takes to make a predictions this controversial !!!

Should get a little hotter today now that the AQI is down in the double digits. Might still fall short of 95.

It will probably literally be the opposite.

Lovely morning at the lake. Smoke isn’t quite as bad as yesterday.

Fun fact: between the start of the airport era in 1939 and 2017, PDX had just three winters with no sub-40 highs before February 1st - 66-67, 99-00, and 02-03.

PDX has had five such winters since 2017.

[Meatyorologist]

Stunning day on the Oregon coast today. No smoke in sight. Blue skies and the occasional stratus. Lushest forest you'll find during the summer on this side of the country

[Phishy Wx]

Do not like.  oof

I think it got put on Level 1 and the click baiters ran with it. They’ve had a good couple days on that fire and it would take a top tier offshore flow event to put the lodge in danger.

I heard from scientifically qualified independents and moderates that CO2 is plant food.
