Maybe one in early August 2017, another in early September 2017, and maybe September 8-9, 2020. In most cases I don't think it's been a huge deterrent. 

The weather patterns that stoke fires are the same ones that direct their smoke into our area. Conversely, the weather patterns that bring in cool, moist air from the Pacific to help put them out are the ones that clean our air as well. Smoke may cool us, but it's usually turning a +12F day into a +8F day.

PDX scored a 64/53 on 9/11/20 under this pattern thanks to burning vegetation (and some residences).

Gross out there. 97/68 here right now. 

[Cold Snap]

84 with a DP of 67 here.

I remember SEA was supposed to have a shot at 100 degrees on 9/5/17 but the smoke kept the high from going above 90 I believe. I remember the forecast high for here was 102 and it only got to 90.

[DeepFriedEgg]

98/66 . And to think this is peanuts for Phil

Yeah, there's a few extreme examples, but that takes some pretty heavy duty smoke at low levels.

Most of the time, run of the mill smoky skies probably only take a degree or two off the highs.

It takes some seriously dense smoke to really make a huge impact on temps. Some of the nastiest, most dense smoke I’ve seen was during September 2020. The 11th-13th were the worst days. The 12th actually felt legitimately chilly outside. 
 9/11 74/53

9/12 59/52

9/13 63/49

That was the best day of our Lake Entiat trip! Basically stayed inside the rest of the time since it got way worse after the 11th. Barely got out of the mid 70’s when it should have been in the mid 90’s during that trip.

She's a beaut. This would be sending -40s into MT during January.

[T-Town]

80 degrees here. Getting hazy but not too bad. I do smell smoke though. 

[Deweydog]

HCS’s are where it’s at. I’ll take a 90/75 over a 105/65 any day.

That's a day to remember! The more naive of mesoscale models wanted to mix 90s down to KSEA. That smoke was so thick it shaded us better than midwinter cloudcover. We basically had no sun that day.

Yeah, dewpoints are approaching 70 across a lot of the metro area.

I think that was the most socked in 48-72 hour period that I've ever seen here, more than any winter inversion. Visibility under a half mile the whole time. Felt very Silent Hill-like.

[TacomaWx]

Up to 84 here…88 unofficially at SEA. Looks like we will get to 85 this afternoon. Don’t think we will be getting to 90 during this heatwave from what I’m seeing but lots of mid-upper 80s seems likely. Probably a couple 90s at SEA.

Pretty standard day in the low country of South Carolina and coastal Georgia.

87 officially for the high at SEA.

What’s your fancy euro temp chart show for the next 10 days 

[Tanis Leach]

Looks like PDX underperformed with a 98. 63 DP. 

 

CVO has the micoclimate kicked in so Corvallis should be cooling off quickly.

Yep...depressing. Won't be long before we will start to have fires close by for ashfall.

[SunAndSnow]

We did it!!

PDX slacking. Even HIO seems to have put up a 100  

[HuskyMaestro]

Was a gorgeous time earlier at Lake Union Park! Breeze felt real good. 

[DeepFriedEgg]

100/69 peak. Definitely more uncomfortable than the 104F day in July

Could be a smoky backdoor blast.  Some pretty active fires in eastern BC and the Canadian Rockies. 

[Winterdog]

Had a high of 83 today.  Currently 75 with a dewpoint of 70 and an 84% humidity!  Feels like D.C.

Extremely bad scenario. Fire starts in like Walterville and it’s game over.

[GHweatherChris]

Humid 93 degrees here today.

[Groundhog]

Interesting situation unfolding here in B.C. Area burnt by forest fire in ‘17. Soil gave way in a landslide and is blocking a river. Should be fun when this breeches.

I'm seriously thinking of driving the 600+ km to hopefully see it. Apparently there is a nice viewpoint of Farwell Canyon from the rim that has a decent resource road getting there. Farwell Canyon Bridge is probably toast, however.
