August 2019 Weather Discussion for the PNW

With the ULL out of the way late this week it looks like there could be enough northwesterly flow to give us at least a few partial marine layer days.

 

 

Indeed... just in the time for the weekend.

And for those who missed it before... ignore day 10 on the 12Z run (that is the high through 5 a.m.)

Thanks! Loved it, what a treat!

A few years ago I kayaked the Salmon river down below. I wanted to kayak towards the sea but was a bit nervous of the tides. Didn’t want to get sucked out to sea so I kayaked inland. Next time going to kayak west...just looks so inviting :)

Will plan it this time so tide can carry me out then when the tide pushes in begin the journey back. May need to throw a fishing poll in and just chill!

I've never kayaked down there but that would sound fun, kayaking downstream towards the Pacific. Bring a bobber and some cured eggs too and catch one of those Fall Chinook hogs they have out there!

Another week-2 heatwave? :rolleyes:

 

I wonder how much it’ll be watered down this time, lol. Over/under on 20 degrees?

It appears that the Seattle-area, Portland-area, and most importantly, the majority of the Cascades, have been subject to less substantial warming since the Industrial Revolution than the rest of the Western US. The high desert in eastern Oregon appears to have undergone one of the most substantial changes. Since our snowpack is often from snow that falls just at or just below the melting point, small temp increases could have large impacts out this way.

Thanks for sharing. So over a 100 years ago, parts of the Southeast were warmer than they are today. That's pretty incredible to see. Maybe the SE ridge was more common and stronger back in the 19th century.

I think a suppressed but strong SE ridge/Bermuda high generally correlates pretty well with periods of cooler global temperatures.

Yes, parts of the NATL and NPAC were warmer as well thanks to intensified anticyclones/subsidence.

 

All kinds of chicken/egg/hatchling stuff going on.

Surprise 90 in the cards today?

 

85 at PDX as of 2pm.

 

We are about to get on the road to Deer Park. Meeting my dad up there who already got a spot. Weather should be about perfect the next two days.

Whether or not we have a warm end of August, I still feel good about October - January 20th.

FWIW, here is how it's discussed in the article: "For all the rising temperatures, there is one part of the country that has not warmed significantly since 1895. It's the Deep South, especially Mississippi and Alabama. A combination of atmospheric cycles driven by the Pacific and Atlantic oceans and particle pollution from cars and factories have contributed to modest cooling in some counties in the already balmy region."

Eh anthropogenic aerosol production has declined substantially in that region since the turn of the 20th century, and it was relatively mediocre to begin with. Impossible for that to have outweighed the urbanization and deforestation/landscape changes that would have added to warming there.

I see, I missed that part. Air pollution out here can cap high temperatures in the summer so that makes sense for them.
