GO BILLS! Even though I'm still rooting like hell for BWagz. 

Totally agree.   Hope Bobby has a career year and the Rams fail to make the playoffs.

I find this rather interesting.

Anyone have any idea why there's less rain along Elliot Bay, Alki and other areas long the Puget Sound?

Since my time of being here in the Puget Sound Region dating back Nov 2001 between Tacoma, Spanaway, Lacey and now here in Seattle the biggest I experienced so far was Hanukkah Eve storm in 2006 was living close to McChord AFB at the time wind gust there maxed 69 mph.

Rainshadow influence, my guess

I was thinking that... from a micro-climate stand point, since we're looking at sectors. I'm thinking that these areas are more shadowed by the Olympics. Very interesting!

Yes... with SW flow the rain shadow usually starts there (and goes north).    The reason places north of downtown get more is from the influence of the c-zone.

12z EPS is very decent

I’ve only seen the one for the Portland area. This is really cool. Thanks.

West Seattle, Queen Anne, and Phinney Ridge neighborhoods are all on top of hills. Those hills force lift and condensation just like the Cascades and Olympics, but on a much smaller scale. Over time those little boosts in precip add up.

Similarly, being down by the water, you are at a constant lower elevation, so no extra precip there. The DT/Industrial area of Seattle is also in the lee of the West Seattle plateau, so they're actually shadowed a bit too! Of course on this scale it's small differences in drizzle intensity.

Annual precip skyrockets as you go east of Beacon Hill and towards Bryn-Mawr Skyway as you leave the Olympic Rainshadow. It also increases gradually north of downtown as you rise a few hundred feet and enter the PSCZ's home of choice.

Np. Was just looking on information on local microclimate of Seattle and bumped into this

Let's be honest. If you are a Seahawk fan you are dumb.

God that was a big one. Biggest of the century for WA. I was living in an apartment on Magnolia, on the NE side of the hill. Usually we were sheltered from big winds, but the dynamics were so powerful on that one that the winds overcame the terrain and bitchslapped my neighborhood. Windows shaking, losing power, blocked roads, everything! I had never seen trees move so much in my life.

Yeah, at most the models have been showing maybe 1/4-1/2" of rain at the very end of next week, with either a weak front washing out as it pulls through, or with some scattered showers. There has not been much ensemble support for widespread rain prior to the 20th. Seems pretty typical to me. We've been blessed by some early rains the past few Septembers, but historically it is pretty normal for this to be a dry month. 

This may be the driest late June through mid September on record for some areas. Some crazy stats for OLM. 1967 is the only comparable period I can find, and I imagine that applies to many other locations.

- since 6/17, .15" total

- highest single day rainfall of .06"

I’m old enough to remember the Inaugural Day Storm. Sustained winds of 50 with gusts to 80. Beaufort scale description of those numbers on land is “Seldom experienced inland; trees uprooted; considerable structural damage.” which is a pretty accurate description of what happened. I counted around 30 downed trees across the road on the way home from work that evening.

So glad I am not the only one on here anymore!!! I cannot wait either! 

[SilverFallsAndrew]

Seriously folx, there is a banter thread for a reason. We don't need your "12" stupidity in here. The only 12 the Seahawks will get this year is loses.

I loved it, tbh I'm kinda bummed out that I left from Puerto Rico which is my home island when I had visited back in 2017 Feb-June if I would had stayed a little longer I would have go to be outside in Maria yeah I'm that crazy when it comes to wind I'll risk it!!!!. My hometown in Maunabo PR has gust of 190 mph

Western Washington maybe. Down here it hasn't been unusual at all except for PDX. One of our wetter summers in recent memory.

2017 was just a little drier in that period out here than 2022.   This year comes in second place.     First fall rain came on 9/18 in 2017 and could be similar timing this year as well.

Hope you guys can become an independent country soon. 

[SilverFallsAndrew]

The PDX "record" if they set it should come with an asterisk. Basically every other place in NW Oregon has had rain multiple times over the past two months.

Just a tad better at SEA and highest single day was a whopping 0.09" on July 3rd.

We'll see about that pretty stubborn Gov down there but that's about case anywhere to some degree. They definitely could of used more help after the hurricane than they got.

PDX has had essentially one rainy day since 6/18...

I think we have another member from PR, I think the young lady from Medford who posts occasionally.

Not unusual. By any means. It really doesn't rain here in the summer, and some years not until mid October.

To followup on my previous post... 

SEA also benefited from a couple bouts of weak PSCZ rain this past month, even though it wasn't much it's also not a representative of the region as well. But still fairly dry.

[ChrisEl Elyon]

Would love to get data records for BFI but don't see any links and NWS doesn't have it like their SEW or SEA

Depending on how long they stay dry this month, could easily end up one of the driest three month stretches on record for SLE.

Man, the 5 month stretch they saw in 2018 may never be broken, though. Just 1.12" from May-September.

[ChrisEl Elyon]

Does anyone know where TWC current temp come from cause it's not matching any airports it's on its own. Showing my current location at 69° not sure what station is using while Boeing Field 70° and SeaTac 72°. Wonder if their current temp output is reliable for data it's what I use for Belltown since I have no wx Station

I know there is a place where you can download daily records from every station on the WRCC site.    I have the daily data for Palmer, Snoqualmie Falls, and Cedar Lake in Excel and always refer to it.   Someone will have a link.

60 to 75 days with next to no rainfall isn't too unusual (especially lately). Once you starting pushing 90 days, though, you'll find very few years with basically a single rain event.

We had 0.02" here in August. VUO right across the river scored an awesome 0.01" on the 6th. 

[Front Ranger]

Per Andrew, this is normal.

[ChrisEl Elyon]

There are also these not to far and a crappy Ambient WX Station on Hull building close to me that reads way to warm on temps but does only good on winds.

SEA NWS site actually has BFI data going back to 1948.

I had a drizzle on the 9th, probably was just a trace though. Maybe we had a few hundreths of an inch then or on one of the marine layer days but never that much.
