I had .65 yesterday and .51 so far today. I’ll be curious to see how my rain stats compare to yours. The Tempest uses a haptic gauge to estimate rainfall and im wondering how accurate it is. 

I have thought about getting the tempest weather station as upgrade. I just have a standard old fashioned rain gauge that I got from my grandpa years ago. It runs pretty darn close almost to the NWS observation sites within 5-10 miles of here so I trust it well.

The Tempest was super easy to set up and has been good so far. The rain gauge is the only question mark but I like the zero maintenance aspect of it.

September will end up cooler than normal at KSEA. Not unusual for +ENSO.

Really? 

[Cold Snap]

Dumping rain here now. Currently 59 after a high of 60. Up to 0.57” for the day and 1.10” in the past 24 hours.

[Ken in Wood Village]

This low is still impressive. I think the next low is to the left of the big low. And I mean I think it is...lol. 

[Ken in Wood Village]

Check out this line of showers coming through the Portland area. 

[TacomaWx]

Narrow band of rain overhead is just absolutely dumping rain. 0.50” today now. 

[TigerWoodsLibido]

0.35" today and that brings the monthly total up to 0.91" Should hopefully break the 1" threshold soon.

[TigerWoodsLibido]

Hopefully Jim and @MR.SNOWMIZER show up soon. Worried about those guys.

[Ken in Wood Village]

Looks like the front is East of Portland and Seattle and cooler/colder air is coming into the area. You can see thunderstorms building behind the front. 

[TT-SEA]

Wow... crazy cool view from Space Needle right now. 

[Meatyorologist]

Haven't had a rainfall overperformance like this in a looooong time. Pouring out with 1.4" on the storm, and more showers training right overhead. Nearly twice what I thought I'd have by now.

[the_convergence_zone]

1.52” after a quick quarter inch from that convective shower. Followed by a rainbow!

It has been raining hard for awhile here. Has been a long time since it’s rained like this…don’t remember it being like this at any point last winter! Over 1.1” storm total here and it’s absolutely dumping right now. 

[Meatyorologist]

The HRRR and the Euro both have a nice windstorm for Seattle Wednesday. Given all the leaves on the trees, I'm a bit intrigued we might lose power. Last time I lost power due to the weather was during the final hours of heavy wet snow on the morning of 2/11/19. And for a wind-related outage I have to go back a month to 1/4/19.

Portland is still missing out on the blessings.

How much did you see in Dec 1996?

This much! Pic was taken after the switch over to rain and it was starting to compact that morning.

From what I remember of 06-07, my senior year of high school in Buckley, it was a cold October, we had a wind then snow event in late November. I remember six inches of snow going crusty hard and som arcticesque days going into December. Then we had our warm up and the worlds greatest windstorm of modern times. Then I remember that the remaining winter was one where snow showers seemed like common place in Bonney Lake. See a couple inches, melt off, wind, graupel, then see rain and then snow.

I dropped out that February and remember an icy and cold period around then.

November and February of that season. I know that I have pics of January 2007 as well but I will need to dig into my box of pictures in the attic. 

[Doinko]

Huge downpour right now, extremely heavy rain

[Ken in Wood Village]

Some lightning strikes have shown up

[MossMan]

.62” on the day. 
Of course 20 seconds after shooting this quick clip of racing clouds while putting the generator away I hear a large crack followed by a large tree of some sort falling either on my property or my neighbors. So close to having it on tape. The sound anyway. 
Oh…And it’s still coming. 

[Ken in Wood Village]

I wanted to post this for everyone. Looks like that secondary low is going to pack a punch for the PNW. Even though the winds are not super strong, with the full foliage on the trees, there is a strong possibility of power outages. The next storm will be interesting to see what happens

[Meatyorologist]

Some intense convection embedded within these rainbands as colder air advects aloft from the west, increasing CAPE consequentially. Wouldn't be surprised to get an embedded lightning strike like down in PDX.

[Gradient Keeper]

It has only been Fall for a few days and it's already active with an atmospheric river, t-storms in the Vancouver metro area up to Columbia City, Woodland, Ridgefield La Center, and now the potential for an early season wind event/storm for the Northern OR and WA Coast, and maybe Puget Sound too. Awesome.

For PDX Last September 25th we were very warm and sunny with 88 degrees. From the 24-30th we ended the month first with hot weather peaking at 90 on the 26th, and then cooled down to the low 70s with about a quarter inch of rain .26" to be exact. Pretty soon we'll be tracking arctic fronts up in the Yukon. Yep. A snowy Nino! C'MON!!!!

Absolutely pouring here! Under the dark red the past few minutes 

[MWG]

Raining since 11am power went out for like 5 minutes just a couple minutes ago.Temps for the 55/66 and currently 55F wonder if our low  for the day will change lol

There were a few strikes around Clark County with that intense downpour s not ago

[T-Town]

Up to 1.14 on the day after some very heavy showers.

0.98” here now. Close to 1/2” fell in ~25 minutes. This should be our biggest rainfall since June 9th, 2022. (1.44”) 

[Slushy Inch]

Lightning!

[Ken in Wood Village]

I think it's going to be a very active night 

[Slushy Inch]

Mariners losing again but we got lightning!

That just passed along the SEA rain gauge so curious what it gets. A lot of stations right at the edge have 1.1-1.3” of rain but just south of the airport around .7-.8”

[Gradient Keeper]

Wow 68.5 dBz!

I have been watching that too.   Thunder reported but only .03 in the last 30 minutes.  Could be that the heaviest rain passed just to the west.

[Cold Snap]

Pretty nice cell over Bellevue right now.

There’s no way. The storm passed over the airport but the heaviest was right over the northern part of the airport. Even if the gauge was on the south end of the airport it would have read at least .05 or more. 

[the_convergence_zone]

Every one of these convective showers seems to be finding me. 1.84” storm total! Best storm in a long time. 

[jcmcgaffey]

Looking back at it the storm was centered over SeaTac. They had to have received well over a .10”.

More lightning than I was expecting. I could see the bright flashes and hear the thunder.

Just .05 since 8 p.m.

Just an absolutely deflating game tonight. I didn’t think it could get much worse after the weekend. At least I have the calming sound of rain to listen to!

Looks like '76.

Cell is now over me and it’s dumping rain!

Yeah. Definitely wouldn't write off this winter, especially if you buy into persistence.

Freaking Verlander. Ugh. This team just doesn’t have it.

Up to 0.98” for the day now.

They had it in August.   But didn't have mental fight to handle the inevitable downturn.   They have seemingly given up.

If the station doesn’t update then it has to be an inaccurate reading. I have always felt the SEA station doesn’t accurately read rainfall but that’s just my novice opinion.
