September 2023 Weather in the PNW

[Cold Snap]

Up to 80 here after a low of 48.

[LowerGarfield]

Hot and clear day in Pullman at the Cougars game. There's some haze to the north. Even in the shade I'm sweating which isn't super common.

I am guessing it will be back up around 80 late in the week and maybe next weekend again here.

Think I will wait to pull the boat out of the water then! Lovely day at the lake! 

[Cold Snap]

Starting to look like fall! Noticing quite a few leaves on the ground in some places.

[SilverFallsAndrew]

Really nice early fall system on the 18z GFS. Don't think this will be the year, but autumn's like 2012 or 2016 are truly special. Once they got going they didn't stop delivering blessings aplenty.

Unless the CFS shows it I ain’t buying it.

77 here, looking pretty unlikely we hit 80 again today.

A few days ago, it was supposed to hit on the 23rd or the 24th. Now it’s the 26th.

That doesn't sound special... give us some variety.   Alternating storms and sunny periods makes for a nice fall season.

Fire in the Olympics really putting out some smoke today in southerly flow ahead of trough offshore.

Looks like a couple of rainfall chances for MBY coming up fairly soon.

I’ll get more excited about the storms modelled for later if the models are still calling for them within five days.

It's so weird to me that people on this forum care about the preferences of others. Wacky stuff!

Tuesday night is looking pretty good from King County northward on all models now.   That was the only rain event that ECMWF showed for the Seattle area for the next 10 days though.

Yes... but it can come in firehose spurts and be broken up with some nice periods and still be much wetter than normal.    I am guessing November and December will be very wet.    That is just a guess of course.   But if I had to bet that it what I would put money on.

I mowed again.

Wow quite the temp difference!

The 18Z ECMWF shows some rain out here early Monday morning and again on Tuesday night... but also shows the afternoons being quite sunny each day through mid-week in the Seattle area and in my area.

00z GFS Day 3.5

Two months from now this would have really drawn our attention. The Great White El Nino Winter 2023-2024.

[Gradient Keeper]

Day 7 is sexy too.

[Phishy Wx]

too bad its the GFS

[SilverFallsAndrew]

That trough the middle of next week drops nicely into Eastern Oregon. They have done pretty well the past month or so. Not a terrible fire season over in that part of the state.

Burns dropped to 32F on the 14th.

If we're going to take the GFS seriously, it shows some pretty decent late September torching for the Willamette Valley.

That's nothing. It can easily hit the 90s in early October.

The current all-time September low at BNO is 17, so they can get cold. The old Harney Branch station was in a fairly similar spot from 1922 to 1954 and they recorded some insane temps during that stretch. The 48/2 on 9/24/26 is pretty out there... So is the -11/-45 from December 1924.

Euro precip in the next 10 days. Ensemble mean is a little damper than operational for most. Perhaps some signs of the rainy season onset showing up?

[Cascadia_Wx]

Friday was disgustingly hot but it ended up being a pretty nice evening at the Oktoberfest in Mt. Angel. We usually camp out on the lawn at my friend’s uncle’s farm after the festivities. Cooled off quick overnight, was all the way down to 49 by morning. Caught a gorgeous sunrise looking toward Mt. Hood.
