August 2018 Weather in the Pacific Northwest

[Dave]

Everybody ok in the south sound? Heard there was an unauthorized take off and a plane crashed into the sound.

Unfortunately, no one in the south sound has survived

All gone.

Part of the plane hit me here in Portland, I'll survive though

[MossMan]

Sounds like a Alaska Air mechanic wanted to go out in style. Even did a barrel role or two apparently before he took her down.

[wx_statman]

I’ll bet much of the difference between this strech and the 1977 one can be attributed to UHI.

 

The warming trend @ PDX is ~ 250% faster than EUG.

 

There has definitely been UHI influence at PDX. Having said that, EUG also broke their 30-day record during this stretch - by 0.5 degrees F (1967).

Interesting that 1967 held the record @ EUG but it was passed by 1977 @ PDX? Or were the two events synoptically different somehow?

 

Just to clarify any confusion, I didn’t say the record wouldn’t have been broken. Just that much of the difference is likely a result of UHI (not all of it). I’m not sure PDX would have hit 90 on the 30d mean without UHI, though.

It was a noble self sacrifice to protest the addition of the third runway and general rampant UHI at Seatac.

Crazy stuff! Didn’t see him but lots of air traffic going over house now!

How the heck did he taxi that thing to a runway? Just crazy

[Front Ranger]

"Mostly in check" now means just a handful of 90-95 type days before the ~100 stuff returns.

 

In absolute terms it's still a total blowtorch for the foreseeable future.

 

Doesn't look like the whole week will be 90-95. Could easily be at least a couple days that don't hit 90.

 

Some model runs were showing the potential for much warmer Mon-Wed just a couple days ago. That was the point.

[Front Ranger]

It’s been a pretty unremarkable stretch out here. Just ask Flatiron. There have even been some model runs that were hotter than what actually verified!!

 

 

I haven't downplayed the remarkable stretch of heat at all.

[Blizzard777]

Turboprop too

 

He must of had some sort of experience

I bet that was the case, but I'm not sure either. Regarding if PDX would have averaged 90 without UHI - your guess is as good as mine. Probably not though. Who knows, maybe we would have landed on 88.8 if this was 1977. There's a pretty substantial area of grass that has been replaced by concrete right around PDX since the 1970's. Something like a 0.3 degree boost in the means wouldn't surprise me, although it would be almost impossible to quantify. Especially since the Columbia River is very close to the ASOS sensor (in fact, closer to the sensor than any of the new development in recent decades), and probably exerts a more significant local influence via evaporative cooling to mute any warming signal from land use changes.

How did this stretch compare to 1977 downtown?

A stray 86 or 87 could spell a serious adjustment for many of us.

Gotta wonder what the insurance folks were thinking when they got the phone calls about this one?

[SilverFallsAndrew]

Absolutely unreal how hot this summer has been and how hot it looks to continue to be. I thought last year and 2015 were bad enough...

[MossMan]

Turboprop too

 

He must of had some sort of experience

According to his conversion with ATC he played video games so he was good! He was surprised by how much gas he was burning while checking out the scenery around Puget Sound! That audio was crazy!!

Global warming

Climate change

Global cooling

etc. etc. 

 

Won't someone think of the emaciated polar bears?

[Front Ranger]

Euro is cooler for later next week than previous runs.

Lower 90s?

[TigerWoodsLibido]

How much does access to the better EC maps cost?

[ShawniganLake]

Lower 90s?

only mid 80’s on Friday. Looks like 98 or 99 on Tuesday though.

Yeah, Tuesday is easily the hottest day of the week for Portland, per the Euro.

 

And the Euro is easily the hottest model for Tuesday.

[Deweydog]

Global cooling showing up on the Langley radar!

[ShawniganLake]

Lightning moving onto central Vancouver Island

[TigerWoodsLibido]

Smoke moving off to the east now. Stars are beautiful. Meteor shower hits its peak in the next 2 days. Enjoying what I can since clouds will be an issue now.

[ShawniganLake]

EPS looks like a blowtorch

I don't know. I could look it up

Pilot: "...just a broken guy. A few screws loose. Just now realizing it."

At one point, controllers tried to convince him to land the plane at the McChord runway at Joint Base Lewis-McChord.

Controller: "There is the runway just off to your right side in about a mile. Do you seen that? That's the McChord field."

Pilot: "Oh man, those guys will rough me up if I tried landing there. I think I might mess something up there, too. I wouldn't want to do that. They probably got anti-aircraft!"

Controller: "Nah, they don't have any of that stuff. We're just trying to find a place for you to land safely."

Pilot: "Yeah, I'm not quite ready to bring it down just yet. Holy smokes! I gotta quick looking at the fuel 'cause it's going down quick."

Controller: "If you could, could you start a left hand turn? And we'll take you down to the southeast please."

Pilot: "This is probably jail time for life, huh? I would hope it is for a guy like me."

[Front Ranger]

I don't know. I could look it up

 

Seems like that might be the easiest way to figure out how much PDX's numbers may have been influenced by increased UHI.

 

In general, though, high temps are not affected by UHI near as much as low temps. SEA is sort of an exception to that, during the warm season.

[MossMan]

Raining!

[Front Ranger]

Raining!

 

Models say you'll be the big winner with this system. Shocking, I know.

Hopefully this will translate into being a big snow winner during the winter season as well!

Tim will still beat you. You might give him a run for number of days with rain.

Sunny here right now... hoping for some heavy rain this afternoon.

Canadian smoke model says that lots of smoke will be coming south from BC by Monday.

The smoke is thick up there now. Clinton has 1.25 miles visibility in smoke. Looks like some of the southern fires will get some rain tonight. Maybe not so lucky in the Cariboo and Prince George areas.

[SilverFallsAndrew]

Looks like some coastal showers being eaten up by the coast range. Probably a partly sunny day with a high around 72 here today.

Normally I would be ecstatic about this but I'm ready for Autumn now. I've already had my heat fix for this summer. If we do continue to torch then hopefully it won't be too smokey.
