Interesting, thanks for sharing that. I guess I wasn’t thinking it was similar to June 2021 since while there are some daily records falling, it’s not absolutely shattering all-time records like that ridiculous event. Is it just due to the position of the max heights being a little further north vs. June 2021?

That's a good part of it. Also the weaker sun, higher moisture content at the surface, and the overall cooler airmass. Remember that those graphs are depicting deviations from average; averages that are much cooler right now than they will be at the end of June when that heat wave fried us in 2021. That airmass was significantly hotter--the hottest ever observed here. This today would be pretty decent by late July standards.

Well shit.

First official 90F burger for EUG

Thought there was one in April. 

[MossMan]

Was the perfect temp for working on the boat in the garage. Interior is now clean and mouse urine/feces clear! Smells much better. 

[NWbyNW]

Wowie.  It is a toasty 77F out there and it feels like it today.  Nice ocean breeze though still.

No way your 96 is accurate, though. Overexposed.

I am surprised to see the WV outpacing areas further north today.

We were at Cannon Beach this morning. Was pretty nice until this afternoon when it got slightly uncomfortably hot. Hopefully we see some thunderstorms tomorrow

[TT-SEA]

An actual trough on the 18Z GFS well within 10 days.    Some variety would be nice!

Didn't even drop below 68 overnight. Looks like 85 home now

Just 5 miles away at Hillsboro they got down to 55, a 13 degree difference

[Eugene-5SW]

If the 95º at North Bend Airport (OR) holds up, it will be a new May monthly record.

[GHweatherChris]

KHQM hit 90 today, 95 here.

Now you choose to trust the 18z?

[Ken in Wood Village]

I like how you can see the difference air masses on this satellite picture. There are thunderstorms on the extreme eastern side of Oregon. The dewpoint has climbed up to 50° at the Troutdale Airport. If it was winter and had these East winds, it would probably be in the single digits....lol.

[TacomaWx]

Stalled out at 86 for now. 90 isn’t looking likely at the moment but still a couple hours to go. Unofficial 88 at SEA. 

[SnowySeeker50]

Looks like the high for today will be 92 degrees.

No... just mentioning that is what it shows.

[Anti Marine Layer]

How hot is too hot for @Cascadia_Wx?

[VancouverIslandSouth]

Currently 86F in Victoria after a 62F low. This would even qualify as a warm day in July around here.

91 at the non-Tim North Bend is pretty nutty.

As he pointed out last week, that area often overperforms in this type of pattern.

Snoqualmie Falls has hit 90+ as early as 4/19 (1934), and five times earlier than today. So not one of the more nutty observations out there, imo.

The 91 at KUIL stands out more to me.

EDIT: Nevermind, misread which North Bend you meant. Yeah, that's nuts.

I think he meant the Oregon one on the coast

Looks like that's the all-time record high for May. The 2008 event only had highs in the low 80s there.

[Doinko]

The ODOT sensor at US 26 and OR 217 has had a 91/74 day so far with a current temp of 91, really crazy

Just giving you sh*t cuz everyone attacked me when I quoted the last big change in a 18z

Didn’t mean to make it seem like an attack sorry. Ensembles supports this run a bit.

Arrived PDX yesterday and hopefully home tomorrow to enjoy some more T-Storms!   What a way to come back home with temps in the 90s! 
Federal Way currently 85* 

Did a little storm chasing on my way home.  Nothing severe but I was under a Tornado watch in Cozad Nebraska. Also stayed in a unique Airbnb in the Ozarks to see if I could attract a tornado . Rain and Thunder sounded cool in the silo ! 

[VancouverIslandSouth]

Currently 88F here in Victoria. Definitely going to be quite a few places over 90F up this way today.

Unique? Pfft, lots of people spend the night at a Silo Inn.

Old all time at KHQM May high was 87 in 2007, yesterday became the new one at 89 and if the 90 is recorded today, that will be the new all time high for May.

57/88 for the day IMBY. Too hot for mid-May!

[DareDuck]

76/46 today and 78/45 yesterday. Fortunately so far this pattern as been much more temperate out this way. Hoping for a nice soaking tomorrow. 

[Anti Marine Layer]

91 in Newport. Not a bad day.

[Deweydog]

Looks like Astoria managed to tie their May GOAT.

That 18z RGEM is actually really intriguing. It shows what looks like an outflow driven convective band from the SSW. Modest shear means fast tower buildups, if skies can remain clear.

Very unusual convective meteorology on display tomorrow for western WA and OR. More akin to a continental climate.

How does tomorrow's setup compare to the one on May 3rd/4th?

Less shear but better thermodynamics. I'd say the severe potential is a little higher for where thunderstorms do form than it was back on 5/4/17, but the storms will also be less numerous, barring some spectacular organization.

Oh I meant the ones this year, didn't realize they fell on the same date! It wasn't really that crazy or widespread but it was the first decent light show I'd seen in a couple of years.

[Port Angeles Foothiller]

84.7 max today, 83.5 yesterday. This is the earliest heat in my 6 years here. We went from way behind with bloom/leaf out to right on time. Kinda amazing really. This will be my best garden year. Sure hope Mother Nature helps out with watering.

Oh lol, I know what you mean now. The potential is better, but storm behavior will probably be similar, if not more erratic. General slow E-W movement with good amounts of lightning.

KHQM hit 91 at least today now.

Southerly surge is reliably taking place

Daughter is in Lake Tahoe and it is raw and rainy. She is amazed at the snowman is around the area

Or snowbanks.....stupid auto correct. 

Maybe there are snowmen?

[Cold Snap]

I wonder if people will be caught off guard by the thunderstorms tomorrow. It doesn’t appear like it’s being talked about as much as it should.

[Cold Snap]

Looks like a 91/54 spread for me today.

[TT-SEA]

SEA beat daily record from 2018 by 1 degree... 89 there today.

[SilverFallsAndrew]

Not a bad day in Central and Eastern Oregon. Highs mostly in the 60s and 70s. 

[TacomaWx]

86/62 today. 2 degrees shy of tying the May record IMBY. Either way impressive heatwave for this early in the season especially in terms of duration. 

[MossMan]

Ran to the lake house to mow late this afternoon, the temp was perfect with a north wind blowing. Neighbors dogs were loving it, you can see the ball splashing into the water and their Lab getting ready for liftoff!
