Rain totals for SEA from 23rd thru 27th. Haven’t counted today yet. 

2.61” — not too bad!

This may actually be the official number from the 23rd thru 28th since I dont think anymore rain is expected for today. At least a significant amount.

Stake through the heart with these model runs. Good thing I won’t be around for this awful weather coming up.

As it stands now... this is the 10th wettest September at SEA.    I pulled the data into Excel to be more accurate.   It looks we won't pass up 1945 and 1971 at this point.    Could move up to 8th with another .07 over the next 3 days.  

Here are the top 10 wettest:

2013 - 6.17

1978 - 5.95

1969 - 5.57

2010 - 4.80

1959 - 4.60

1972 - 4.10

1948 - 3.85

1945 - 3.51

1971 - 3.51

2023 - 3.44

 

On the other end of the spectrum... the top 5 driest:

1991 - 0.00

1975 - 0.00

2012 - 0.03

1993 - 0.03

1990 - 0.05

i bet the weenie whining on the CERN forums was out of control after September 1993 having just gone through 90 and 91.

3.35" for the month here at Eastside Tacoma we average 1.57".

The early 90s were the glory years of dry Septembers!  Of course September of 1993 followed a wet summer so it makes sense that month was very dry.   Interestingly... 1993 was a very dry year overall.

@Port Angeles Foothiller are you getting decent rain this morning?   The flow is more westerly now so your area should be less shadowed.  

0.01” Every storm dies before it gets here. It has become comical at this point. Now we ridge? Lmao. I did get a rainbow over the storms that never made it here. Yes… that is a sprinkler.. can’t let the $300 in grass seed go to waste.

Interesting to see we have an analog year in the top 10 just ahead of us...

amazing how the models were so locked into troughing a few days ago for this period and have completely flipped.

How is 2022 not the driest? I had 0.00" here for July, August, and September in 2022

SEA had .25 in September last year.... came in 8th driest.

Nice pics.

Can't even imagine watering here now after more than half a foot of rain this month.

00Z ECMWF actually looks like the GFS now.   But the EPS hasn't shown any ridging signal so it's probably just model noise. 

Yeah guidance definitely doesn’t agree w/ me at the moment. We’ll see what happens.

I’ll take a troughy and wet pattern literally any time of year. It’s so rare these days not to have some sort of record setting ridge sitting on top of us.

Honestly we’ve had some decent rain and some normal fall like temps the last 7-10 days, and that looks to last another 3-5 or so. So by then, judging by modern climo, we will definitely be due for at least 2-3 weeks of flirting with near record smashing warmth again.

Let's hope ridging wins out until inversion season begins, then constant pineapple express aimed into southern BC with WA and OR under subtropical airmasses all winter.

Same argument can be made for people who love big storms or chase severe weather.    Nature is going to do what its going to do... its silly to say those people are morally wrong for being fascinated with destructive weather.    Morality is not concept that applies to nature.  

I actually agree w/ u on this one. I’ll readily admit I crave severe weather, though the destruction that can result is always depressing.

I really don't follow this debate on early October weather. It's not true rainy season yet, it's blocking season. Do we really want to waste a trough on early October? This past week was a real anomaly, usually the storms this time of year drop a quarter inch of rain at a time.

Appears SEA is about to notch their first below normal temp month since April.

[TT-SEA]

12Z ECMWF is a little slower to build the ridge... potential definitely exists for a AR event in NW WA and SW BC next week.

Forgot to mention, we picked up another 0.25" of rain overnight. Every little bit counts in a climate where we can never have enough rain.
