86 at SEA today.    Warmer than the ECMWF showed.   It's cool bias might be coming back for fall.   GFS was closer.   Maybe some more 80s ahead... but next 2 days look chilly.

I’m gonna be honest since no one, perhaps by choice ever brought it up. But the Euro’s performance as of late has been somewhat poor. I’m sure, it’s still better than the GFS, but I was not impressed with how it handled systems that went through late August.

Looks like these storms are going to start clipping the southern metro area soon. I’m ready! 

[FroYoBro]

Been seeing tons of lightning in the air to the south over the last 20 minutes. Not close enough to hear yet.

It was solid most of summer... cool bias was gone.   Not sure what is happening now but it seems to be creeping back in and its missing more frequently.

Seeing a lot to the west here too, but there are clouds covering them

Ended up with a warmer than expected 89/58 day here. Went on a hike today and leaving the Portland area it was already in the mid-upper 70s by late morning. The thought crossed my mind, could PDX hit 90 today? Of course they did.

Hoping for some good storms tonight to make up for it.

Regional. But seems evenly distributed in the region.

Looks like summertime warming has been more pronounced in NW Oregon/SW Washington and parts of the south sound than it has in the south Willamette valley. At least according to this map.

Saw some lightning pretty close and heard a bit of thunder

[Jakewestsalem]

Just got back from a wedding in Aurora, Or.  Crazy lightning and torrential rain on I 5 south of Woodburn.

Sorry that my wife had to drive because I had too many whisky sours!

Now watching lightning to the north from home. 66f dp of 64. So nice!

[The Blob]

I looked through the dock door window and I can see flashes here in Troutdale.I hope it is a good show.

[FroYoBro]

Insane lightning output from that cell to the south. Strikes every 5 seconds or so and and starting to hear thunder now. 

[Ken in Wood Village]

I'm in Fairview and I can see the flashes of lightning from the storms south to southwest of me. It's non-stop flashes. I drove down to West Linn and got these flashes. 

[Ken in Wood Village]

Here is the lightning output on the satellite picture. 

[SunAndSnow]

Seeing some flashes looking south towards West Linn! 

[Doinko]

That cell to my west is also putting out a good bit of lightning

[Requiem]

Constant lightning to my south and west

[Cold Snap]

Lots of lightning in the cells south of Portland. Nice you guys down there are getting a good show!

[FroYoBro]

Current sky conditions to the south. 

[Doinko]

Very frequent lightning to the south, no thunder yet

Update... official high came in at 87 at SEA.

The 18Z ECMWF showed 81 this afternoon at SEA... off by 6 degrees in the first 6 hours of the run.

[Deweydog]

That cell has been Uber persistent.

Still seeing some really nice lightning strikes from that 

[Perturbed Member]

One of the nicest light shows I've seen here in a very long time. Such frequent lightning.

Good win. Not 81-7 tho.

Look at those empty seats. Plenty of empty space at Autzen today too. As both teams move to the big ten expect their popularity to wane as wins become more scarce. 

Probably will be a net positive because of the money and higher fan interest. The opposite for Waazu and OSU.

It got up to 87F here in the mid to late afternoon.

[Doinko]

Sadly the rain is just a couple miles south of me but still a really nice light show

[Doinko]

Seeing some amazing bolts of lightning right now

 

[Cascadia_Wx]

Lightning is distant to the south and west here but still neat to see. Looks like these storms generally ended up about 25-50 miles west of where they were modeled. Great for Washington county!

[Cascadia_Wx]

00z Euro a little cooler overall. Nice to see.

Obvious lie. Jesse is a Suburu ho.

The GFS warm bias is astronomically larger than any cool bias the ECMWF may have, yet you constantly harp on the latter.

It was amusing at first, now it’s annoying. Bordering on misinformation.

[Doinko]

Still seeing flashes of lightning to the NW, and that cell near Hillsboro is getting strong sgsin

Really impressive how persistent this has been. Still seeing flashes and hearing some thunder too.

KHQM making a run at 90°, was only supposed to get up to 80°.  Currently °92 here.

Hey @Front Ranger why so confused?

Tim is like the biggest Euro bro on here...

Didn’t realize PDX hit 91 yesterday. Wow.

Yea, Troutdale Airport observation said 90 or 91. It was very warm. I was surprised I didn't get any thunderstorms in my area but I did see a lot of lightning flashes from the storms south and west of me. It was amazing light show.

[SilverFallsAndrew]

That line of storms was persistent. Went to bed around 10:30 and there was still thunder rolling in the distance. Great stuff. 

[SilverFallsAndrew]

Ended up with 0.23”. Mist hugging the landscape this morning. 

[The Cats Meow]

Has anyone on here ever been to Burning Man?

It looks really muddy this year.
