September 2019 Weather Discussion for the PNW

[TigerWoodsLibido]

At least we had two arctic blasts that winter. February 2014 had like 7” of snow if I recall.

Yes 13-14 was almost as good as 18-19 even though it was very different.

 

Also just had a boom here.

[Dave]

Yay! More thunder. Lots of downpours too. I'm sure it has rained at least an inch at my location, but the airport gauge isn't showing anything near that.

[jakeinthevalley]

Partly cloudy and dry here... 68 degrees.

 

I have that same sticker on the back of my car! Painful though, as I am a Duck fan with a Husky daughter!

[TigerWoodsLibido]

It’s rained over an inch and a half over the last 2 days at EUG.

Yeah for the south valley. Up here in the foothills 2013-14 was pretty awful for snow. I think Corvallis and Eugene had more snow than I did that winter. 

[jakeinthevalley]

Saturday looks like it could potentially be a pretty nice day down here in NW Oregon.

Hopefully Sunday holds on. Taking some friends to O'Fest

[TacomaWaWx]

Almost totally sunny around the entire Puget Sound region this afternoon... all of the activity is to the south and also to the northeast as the models showed. A really nice afternoon.

 

very nice day today. 70 and sunny here.

My wife wants to go...I've been too many times.

[SilverFallsAndrew]

Flood advisory for the Willamette Valley.

[El_Nina]

Top of Mt. Hood is white.

[TacomaWaWx]

Gfs looking pretty wet for Thursday evening through the weekend.

[TacomaWaWx]

Top of Mt. Hood is white.

There’s been snow down to 9,000’ on mt.rainier in the past couple days.

[Omegaraptor]

Flood advisory for the Willamette Valley.

Nothing even close to flooding here. And there won’t be any.

[TT-SEA]

Actually... Friday afternoon and most of Saturday will probably be dry and fairly nice.

I haven't been in ages, but for years I would alternate between O'Fest and Pendleton Round Up. Just going for the food Sunday

Cliff Mass is saying the warmer than normal water off the coast has contributed to all the thunderstorms.    It sure feels like things are unusually "juiced" up right now.

One reason that values were so high was the blob of warm water off our coast.  The  BLOB not only contributed to warmth at the surface but more water vapor--important fuel for instability.   The eastern Pacific sea surface temperature is roughly 5 F above normal and that implies substantially more moisture in the lower atmosphere.  At the same time, an upper level trough was bringing in cooler than normal air above the surface (see map for 500 hPa...roughly 18,000 ft).   So warm, humid air at low levels with cold air aloft.  That means a large change of temperature with height and lots of potential instability.

[jcmcgaffey]

Crazy!

 

Very localized it appears.

. That was why I posted that Everett report because it was similar to what happened over here with areas getting over in inch and then everywhere else more than a mile away had hardly anything. It was like a spotty convergence.

[ShawniganLake]

Dry here today. Victoria YYJ is up to 0.05” for the month

[Omegaraptor]

It could always be worse, I guess. We probably got another .2” today.

[Requiem]

There are still lots of thunderstorms developing out there, so......still opportunities. Understand you may be pessimistic, but...

[TT-SEA]

Salem is getting pounded right now.

[Requiem]

Ooh, looks like Salem is getting quite the beatdown.

[TacomaWaWx]

Wow what a run the last few days have been regarding convective heavy thunderstorms in WA and OR.

[TacomaWaWx]

A lot of activity on the radar in the PNW pretty much everywhere besides the Puget sound. Lightning 30 miles south of here in the eatonville area it looks like.

Portland ain't getting much either. I do see showers to the west, though!

[TT-SEA]

72/59 at SEA today... good for a +3 thanks to the warm low temp.     Looks like OLM also ended up at +3 for the day.

 

Not bad considering the colder than normal 850mb temps today...

No dry Arctic fronts this winter!

Looks wet up there late in the week for you guys. Probably many more days where it will be very different up there than down here!

[Jesse]

No further rainfall here today, but did have my coolest high temp since June. 65 degrees.

[BLI snowman]

0.96" in an hour at SLE with that thunderstorm.

[Omegaraptor]

Wonder when PDX will manage its first sub-50 low.

[Jesse]

Wonder when PDX will manage its first sub-50 low.

Possible in the wake of the cool trough early next week. But their low temps are so crooked these days who knows.

[Guest CulverJosh]

I posted a political post and got moderated. I have onlu read 50 in the last week.

[Blizzard777]

72/56

morning clouds afternoon clearing

Seems like thunder cells are and easy gig this year as of late

[Frontal Snowsquall]

Yes 13-14 was almost as good as 18-19 even though it was very different.

 

Also just had a boom here.

Now all you need is to experience a huge January snowstorm down there.

[Guest CulverJosh]

[Guest CulverJosh]

Been lame for convection over here. But we have greened things up for sure.

[Omegaraptor]

January 1950.

 

The 70th anniversary is coming up this winter!

 

But anyway, when was the last time January delivered for the south valley? For Portland the answer is obvious, but of course that event was a Portland special.

[Timmy Supercell]

As the evening goes on, slightly less clouds. Almost had thunder earlier with a quick 20 minute shower around 3pm. Decided to take advantage of this break by shooting the breeze at Lake Ewauna.
