S L O W Weather Pattern

9:30pm Thursday…

I’ve been extremely busy the past few days with the Junior Parade, doing all 5 evening shows (Steph is sick), and prepping for a big family trip next week at home.  So no postings, but not much to talk about here in the first week of June weatherwise anyway.  We hit 83 in Portland today, our 3rd day into the 80s.  The warmth has been nice after 2 1/2 weeks of cooler than average weather.

I was working out in the garden today; it’s drying out nicely now.  I finished up planting the last of the warm weather veggies so now it’s just a matter of watering and waiting for the next 2 months.  Not that many of you care about my garden, but it’s my blog so I get to talk about it.  I’ve planted eggplant for the first time.  That’s IN the greenhouse because I’m sure it wouldn’t do well at my elevation with lots of 45 degree nights in summer.  Same with cantaloupe and tomatoes.  They are in the ground, but in the greenhouse; every day in summer is at least 80 in there, many days up around 100 or so.  They should like that!  In fact the tomatoes I planted during the warm weather in early May are growing up real fast.

In the short term, a marine push this evening is in progress and that means some decent cooling tomorrow, we’ll stay in the 70s instead of lower 80s.  A dying front drags across our area in the afternoon, but at worst it’ll turn partly cloudy.  Then not much of anything happening Saturday and Sunday…thus a very nice weekend on tap with mostly sunny skies and highs in the mid-upper 70s both days.

Models did real well with the warmup this week, I remember seeing a few comments about a week ago to the effect of “I’ll believe it when I see it…”.  Now you’ve seen it!

Now models are all in agreement showing a signficant cooldown with an upper-level trough by the middle of next week (Tuesday/Wednesday).  Take a look at the 12z GFS and 12z ECMWF ensemble 850mb temp forecast charts:



They both show the cooldown, then a return to near normal temps about 10 days from now.  The trough next week doesn’t appear to be real wet, although that could still change.  The biggest effect will be the cooler temps and a lot more cloud cover.  What about beyond that time?  Here is the twice weekly run of last night’s ECMWF.  These are weekly maps of 500mb height. Next week’s trough shows up nicely, but notice a strong ridge over or just west of us the following week or two. That COULD signal a warm 2nd half of the month. It’s interesting to note strong warming doesn’t show up on the time series above, could be ridging just far enough offshore to keep our 850 temps from going too high. That would be a dry pattern too.





And finally…remember this?  June 2003 saw a nice heat wave very early in the month.  I clearly remember the east wind blowing all night long out in Corbett (I used to live in the wind) with temps remaining in the 70s.  Felt like the warm trade winds in Hawaii!

    I now believe that the parade will be dry, yes. What I just can’t believe is how sequestration has eliminated the Navy ship visits and reduced Fleet Week to about 3 ships. Remember when, like, 2 dozen or so ships came here each Rose Festival, including several destroyers? So sad.

      40 years ago tomorrow I marched in the parade. Back then, all of Portland’s high school bands got to march in the parade.

      And the fun center was over by the Lloyd Center. And it cost a lot less. And it was safe. And no mud.

    • gidrons says:

      Well at least there’s no mud this year, so you get 1 out of 3.

    • yeah and remember when gas was under $1.00 p/g ?

      Back when I was about 15 and my sister joined the navy our family was in tied to ride a navy ship from Longview to Portland. That was a fun experience. Can’t recall what ship it was.

    I might follow Mark’s idea and put the lone tomato plant we have here in the greenhouse until July. As many know at least in my area, the area around McChord Air Force Base (JBLM) can still get quite cool at night in June even.

    My lows for June here in Southeast Tacoma are as follows along with the daily high…

    1st 73/48
    2nd 68/53
    3rd 74/49
    4th 79/46
    5th 77/49
    6th 78/50

    I am wondering also if it would have helped to plant it in a dark colored pot as well. The pot I have it in is white and is large for lots of root growth and I already have a tomato plant cage over the top of it. In the last 5 years here I have actually been successful at growing tomatoes in part because I have a greenhouse like Mark to start them in for the season.

    On the significant cool down; I believe it…….I just don’t want to see it!!

  5. Hoping for 2003- or 2009-esque temps for June as a whole this year. And then – as Boydo said back on Easter – a “Mediterranean” summer on par with July and August of 2004.

    Sitting here in Fairbanks alaska this evening. High temp was 66 today. Currently 65 @ 9:30pm because the sun sets at 12:30am
