September 2023 Weather in the PNW

[Deweydog]

46!

[YahRaEl]

Has anyone seen one of these yet on here? My friend is pretty sure he did but didn't remember to take pic and didn't focus much on it but somewhat remembers black front, rusty rest of body so maybe a Cool/Active at first, then mild and calmer rest of winter

YES!!! Boating season extended!!!

[Cascadia_Wx]

Ended up with a 79/59 day on Wednesday. Morning clouds and afternoon sun. Wall to wall sun and 89/53 day yesterday. Fell to a cool 54 this morning, 62 currently. At least this has been a more traditional September warm spell with the nice overnight recoveries. Even PDX fell from 90 yesterday into the 50s this morning.

EPS looks a lot better for that period than the operational.

Don't worry... the next run will be completely different.    The 12Z run was already much different than its 00Z run even at 120 hours.

Looks like the GFS PNA has things all figured out!

Given the range of solutions we have seen in the operational runs with ULLs all over the place... the ensembles will probably look quite flat.   The reality could be much more divergent than usual depending actual placement of the ULLs.    Could end up cold and wet or even hot at times.

12z Euro would be such a blessing

[Cold Snap]

Up to 81 after a low of 49.

[Tyler Mode]

90 after a low of 47.  3rd latest 90 for me since 2011.

September heat is way different than mid summer.  It was comfortable until early this afternoon.

[Rubus Leucodermis]

Currently 79.2°F after a max of 80.7°F.

Ah, there it is! Was wondering where you were.

[MossMan]

A little toasty out.

I have to say I do remember the day when mid September felt like mid September…It has not felt that way today!

We said that 80s were supposed to be done starting on 8/28.   Almost 3 weeks later and here we are.

September 2011 had 9 days in the 80s at SEA... today is only the 4th this month and will probably be done after tomorrow.

Even though skies have been sunny and blue. There are still some wildfires burning in the Pacific Northwest. A pretty decent sized one burning in the central Oregon Cascades. A few small ones on the Olympic peninsula and then some more small ones in the North Cascades.

Yeah. Can’t wait until this gross weather ends.

SEA is running almost perfectly normal for the first half of September.   This month has been pretty much climo so far in terms of temps.   The were some complaints yesterday when someone described a climo low temp map as "gross".    Double standard.

Devestating Trendz for Eugene on the  Euro. From the 90's to this:

Damp, too:

[TT-SEA]

SLE is only running +1 for the month.

Monday and Tuesday look quite nice... lots of sun and temps only in the upper 60s to low 70s.   Then maybe some rain for the Puget Sound area on Tuesday night.

[Meatyorologist]

Sunday looks to be the start of serious relief here. Monday will be a cloudy, nearly sunless day. Also, that trough on the long range 18z GFS is the coldest it's modeled yet this 'Fall' season.

Not to nitpick... but the ECMWF shows decent sun on Monday with just some high clouds after a weak c-zone fades in the morning.   But the ECMWF could be wrong.

[TT-SEA]

My sense is that next week is similar to this week and last week with cool weather for the first few days and then up around 80 by the end of the week.    Sort of been the recurring theme this month.    Monday/Tuesday have been the coolest days and Friday/Saturday have been the warmest days.
