Wet wet wet. Like California last winter. 

We saw something similar last year from Oct 22 - Nov 7 and when was really wet up here.    Then it all slipped south for the winter.   Would not be surprised if that happens again this year.

18z has a couple days, 9/30 and 10/3, that struggle to reach 50F here, both due to wrap around bands of rain from two separate cutoff lows.

Tis the season for a renewed following of the GFS temp output!   Based on my experience in the warm season... its usually way too extreme on both ends after about day 5.   As Phil is prone to point out.

What a gorgeous early fall evening out. Clear and 61 currently. Some light morning showers then partly cloudy by the afternoon today, 67/53 spread so far.  Should get well into the 40s by morning, possibly the coldest of the seasons so far. Love seeing the wet pattern show up in the mid range.

[TT-SEA]

12Z EPS was wetter than normal for the next 15 days... have not seen it show this anomalously wet for a long time.

We got snow here twice in that time frame. 5” and 8”

A nice set of progressively cooler days here since Sunday. 73/51 spread that day with partly cloudy skies. 72/55 spread on Monday with similar sky conditions, and finally a 70/48 day yesterday with sunny skies early and increasing clouds late. Took a drive out to Astoria on Sunday and it was gorgeous.

Very breezy but beautiful afternoon up here in Bellingham.  I'm really hoping the winds die down for tomorrow, we are going to the San Juans, and while I love it when the waters get rough, my wife gets sea sick if I swirl a glass of water around in front of her face.

Gonna get down to 44-45F tonight. Brrr!

Friday looks to be the last high 70's of the year, then the wonderful faucet turns on from there. Just in time for fall quarter to start at UWT.

Could get to 70+ in the first half of October.     And that is still 10 days away.    We often get another 7-10 day dry, sunny spell in October after the first rainy period.   Conversely... when September is really dry and the rains hold off then we usually crash for good in October.

If you look hard you can almost see the house I grew up in!

My garden out back would love some 70s sunshine in October, especially the tomatoes that have run rampant. Either way works for me, just looking forward to the orange and red trees!

This rainy period should help prolong the fall colors as the trees won't be stressed.   Last year was not good in that regard.  

[Port Angeles Foothiller]

Down to 45 already. Clear night, no wind. This might be the night. Covered what I could in the garden. 

[Frontal Snowsquall]

Fall equinox is on Friday at 11:50 pm PT. Anybody have any celebration plans? It will also probably be the last warm day of the year. Good day to enjoy the warm sunshine before cool and wet weather arrives!

The view looking west from the column parking lot. Had a collision there in April '22. Lots of good memories of a picnic or two on that hill.

Down to 52 in Troutdale.

[Meatyorologist]

Cooling down here faster than I expected with clear skies up and down the Sound. Got to 47F just before midnight and steadily dropping; first 40s of the season here! KSEA down to 53F but there are some mid-upper 40s a mere jaunt from the airport. 45F is an attainable goal for them tonight if the inversion deepens.

[Meatyorologist]

45F here. Opening the window you can feel the cold air pouring in and crashing down to the floor like a waterfall. dense shitt #justweeniethings

Both 00z models (GFS, EURO) runs are pretty much following the same script for the next 10 days. And they hardly ever agrees with each other. 

[Cloud]

Look like SEA is about to get its first sub-50 morning lows since Jun 19. It’s a tad chilly right now. 

[TigerWoodsLibido]

Down to 43F. Really calm and nice out there.

[The Blob]

Down to 46.

[Cloud]

These incredible wet runs are becoming the norm as of late. If verify we’ll complain about how sick we are of the rain by 1st week of Oct. 

[snow maniac]

Brrrr 37 degrees this morning 

[Omegaraptor]

PDX has fallen to the 40s for the first time since June 19th!!

[SilverFallsAndrew]

Looks like out forecast highs drop into the mid 50s by next week. 

[TT-SEA]

Interestingly... Saturday looks wetter than Sunday on the ECMWF.    Also noticed that the main moisture plume sort of breaks apart on arrival on Monday and we get more rain in the post-frontal set up than with the main front.    I would prefer the solid AR solution to run up big totals across the area more evenly.

Hey @Front Ranger OLM with a 36 this morning!

SEA with a 47, BFI 46, RNT 48, PAE 48

It’s gonna rain buddy, time to prepare the ark.

Tim probably very much prefers it, he wants a "solid AR solution" so it can get back to being sunny ASAP. I mean, he even mentioned that's what he wants.

He’s our bloviator and chief. Conversely I have no agenda, I just want everyone to experience the blessings.

With the 36 at OLM this morning, hopefully we'll begin to get our winter folks back soon-ish. I'm surprised we haven't seen Jimbo yet. Hope all is well w/ him!

No doubt it will be wet... just delving into the specific details now that its getting closer.    And actually cheering for a massively wet week to make up some of the deficits.

I am cheering for everyone to be "blessed" as well.    No agenda.   This is the normal time of year for the rain to get going.  And you bloviate like no other.   You have ruined the word blessing forever with gross over-usage.

Warm season is over... not concerned about it getting back to sunny.   There will be plenty of sunny periods in October.   What I really don't like is massive rainfall deficits.   Need to pay that debt back soon.

I hope it stays cloudy for a few solid weeks, TBH.

Killed by downsloping easterlies on Monday. The second system approaching at the end of that loop is going to be the wetter one.
