5pm Friday…
The weather pattern the next 7-14 days looks unusually stable for early June. Little to no rain, but no extremes of heat/cold either. Take a look at the ECMWF model rain accumulation for the next 10 days, showing essentially dry conditions through the rest of the Rose Festival:
And the GFS for the next 14 days showing 1/2″ in western Washington but no part of the west side even gets 1″ during that period! Oregon gets little to nothing:
Neither shows anything significant for sure in the next week, thus our totally dry 7 Day forecast.
The reason for this is a persistent ridge of high pressure to our west in the Eastern Pacific. It’s far enough away that we don’t get offshore flow and hot weather, but close enough to keep cold troughs from digging right overhead. Notice the ECMWF 500mb height anomaly forecast for next Wednesday, 
then 4 days later on Sunday the 8th, 
then a full two weeks out at hour 360: 
They all look pretty much the same. I should point out some models have the ridge backing a little farther to the west, allowing a chilly trough with showers to set up somewhere around the 10th day. We’ll see how that pans out. No matter the details, the weather pattern looks real nice for early June with no hot weather but no period of cool showers either…enjoy.
By the way, today is the anniversary of the Vanport Flood, the one that destroyed a large city on the north side of Portland. I’m not going to recap the whole thing here. But you can read a previous year’s blog posting to get all the details:

Thank you for the pictures of Vanport. I am one of the survivors of that disaster. My dad & I saw the break as we were bicycling on that Sunday and were one of the last cars out. The authorities were not allowing any trucks into the area as ‘It might cause a panic’. I have some original pictures of Vanport and what was left when my parents were allowed to return for what few items they could salvage.
Did anyone take a look at last night’s 00z GFS?
Two words:
Bone. Dry. Not a drop of rain, zero QPF through the 20th of June. If that holds that will be quite a long dry spell for June. My next question would then be are we entering the Summer dry season earlier than usual. I guess we’ll find that out in a week or so.
Today was such a nice day I had to for a walk after dinner because I wanted to take a nap in the backyard lol!

I was surprised at how long the clouds took to clear today. Went to Freddie’s at Gateway around 8 this morning and when I came out there was a nice drizzle going on. Very refreshing! They finally have Otter Pops at the store … a sure sign that Summer is almost here! WooHoo!
June Gloom here on Bainbridge today. 4PM and blue is just barely starting to show in a few spots through the overcast. Currently 64 degrees. Even if we get a bit of sun, it’s not going to be a warm day.
Lame. Been sunny here all day and haven’t seen a cloud. Was 76 an hour ago and looks like its starting to cool a little now. Sometimes I wish I could have a few marine clouds here but that will never happen.

I really hope this summer is big on thunderstorms, had a few big ones here last year but I’m hoping for some golf ball sized hail and it booming so loud that I have to cover my ears.
TRW’s are nice to watch from a distance. Unfortunately they also start a lot of forest fires. If we do get them I hope they come with copious amounts of rain. Peace.
T-storms to my south and east. Grrrr
Yeah, amazing weather today! Just a few degrees warmer and it will be perfect…
First time in over a month that both Saturday and Sunday were warm and dry!

Okay, so last week the word was warm and wet for June, now this week it’s warm and dry? I don’t think anyone has a freakin’ clue…
Pretty sure you nailed it with that freakin’ idea, W7!

I sure hope we don’t pay for this with a wet/cool period in July or August. I would be happy with ZERO precip from July-September other than the stray albino donkeys…….
Interesting, maybe we’ll have two straight months above normal temperature wise, w/o any real heatwaves. Thanks for all the great info Mark!
18 days at or over 70 in Salem this May. Not sure of the record but this year has to be close to it. Probably less than ten days through September with highs less than 70 degrees. My favorite time of year by far. I really liked last Winter with it’s cold spells. But I couldn’t take four straight months of it. This kind of weather I can. When the weather finally turns Fall like in October then we can look forward to the OMSI weather conference. Maybe Mark’s presentation will be the cat’s meow again. Peace.
Hmmmm…….now the freezing level is 11,000 ft and the summit temp is 44? I just don’t understand it I guess. Mark?

This is perfect weather for me for this time of year. Not too hot, not too cold. Mark, can we have this weather all summer, please?
Awesome anvil clouds this evening from those tstorms up by rainier. Ones column changed direction a couple times with a long anvil and an overshooting top. Love that
Today was just perfect. Clear, not too warm or humid and a nice afternoon breeze. This after a low of 42.5° this morning. And I’m not in one of Mark’s “colder outlying areas,” but in east Portland. I’m sure that other parts of the city had similar lows this morning.
gorgeous is all I can say.
