A Slow Thursday Evening

Snapshot[1] Well, we have a moderate onshore flow, no heat wave in sight, and no rain showing up on the maps either.  Add to that no good chance for thunderstorms in the near future and you get a very slow weather evening.  Even the fire situation has improved with only 4 major fires ongoing in Oregon and Washington.


This morning’s low cloud cover inland was limited to mainly east of I-5 north of and Oregon City to Sandy line.  It should be a different story Friday morning, I see Longview had clouded in by 10pm and temps are running a few degrees cooler this evening too.  I still don’t think it’ll be a marine layer up to 3,000′ which can take most of the day to evaporate.  So I’m planning on a noon breakout at the latest here in the metro area.  The westside may still have limited cloud cover.


Saturday through Monday:  Rising heights in the upper atmosphere should keep the marine layer lower and closer to the Coast.  Temps should make it into the 80s as a result.


Tuesday and beyond:  A bit lower heights and troughiness offshore spell another period of morning clouds/afternoon sun.  It doesn’t look like last summer where a sharp trough lingers near the West Coast…for now.  Mark Nelsen

    It’s the global warming again…….

    High of 89 here today, but cooling off nicely now with a NW breeze. That haze looks like smoke to me, I can just see it to the south of me.
    Rob, it looks dry to me through the end of the month. If anything we’ll have a heatwave before we get any real precip.

  3. HIO Phil (Punxsutawney) says:

    Looks like there are more of those thin volcanic clouds just barely visible over NW Oregon/SW Washington right now. Maybe the same ones, though I thought the ones this morning were moving south. Look NW into the sunset to see them.

    Forogot the weather part: I am at 71.3 dropping nicely. I am mostly clear except the usual PNW high clouds to the NW of me but they are very minimal. 🙂 Too bad next weeks storm is false.

  5. The Triforce says:

    Wow Mark. 🙂 The weather monkey is on it’s way home. At least he isn’t going to be here during the 10pm brodcast unless it goes on to midnight.
    He is in the blog mobile.

    I’m timelapsing the “ash cloud streaks” this evening…we’ll see how it shows up on-air at 10pm.

  7. Justin (Brush Prairie, WA) says:

    Volcanic eruptions can affect climate by pumping out SO2 into the atmosphere, but it takes a colossal eruption from a major volcano to do so.
    The 1980 eruption really didn’t have a noticeable effect on climate, although the summer of 1980 was considerably cooler than average across the PNW and recordbreakingly hot across the Midwest.
    Pinatubo was the last eruption to pump out enough sulfur to cause global cooling, and as far as I know the eruption this week in the Aleutians wasn’t even close to the size and magnitude of the Pinatubo eruption.

    Anthony, I don’t think winter 80-81 was all that dry. It did have a dry Janurary, 2.22″ in Hillsboro vs. around 6″ on average. Nov & Dec were above average, at least in Hillsboro. Now the real fun started in the fall of ’81 with the November 11? wind storm, snow in December and 32″ of precip Oct-Feb ’82.
    Perfect temps outside today for a summer day in my opinion. It isn’t going to get anywhere near 80.

  9. I remember Mark posting something about it a couple years ago, but there does seem to be a correlation between volcanic activity and cooler temperatures. But from the initial number I saw, in 1980-1981 (Winter following the Mt. St. Helens Eruption) we had an extremely dry winter.

    Luvry…
    Any effect on our weather?….seriously doubt that.
    Pilot reports show that it’s 30-35k ft.

  11. Luvry (Tanasbourne) says:

    That’s pretty BADA$$! Do you know how high they are?
    Do you think that will have any effect on our weather in the next year? I know it’s pretty tough to call but just curious as to your thoughts.

  12. ChuckyD81 says:

    Luvry…
    Faintly I could see it on yesterday while driving in to work. I had polarized sunglasses on so I’m not sure if that made any difference or not…can’t remember if did a double-take and looked with my sunglasses of.
    But yea…that’s what it is…remnants from that eruption!
    I have good “sources” that say that’s it!

  13. HIO Phil (Punxsutawney) says:

    Thanks Chucky,
    I noticed it on satellite this morning and wondered about it.
    The marine layer has definitely filled in here this morning.

  14. Luvry (Tanasbourne) says:

    Marine layer holdin strong here this morning, I would bet it doesn’t break until about noon. I’m putting our high right around 76 for today. I was completely sunny out here at this time yesterday.

  15. Luvry (Tanasbourne) says:

    WOW! you got some eyes there Chucky. So you really think that’s what it is? Crazy stuff, thanks for the link and the update. Have you checked to see if you can actually see it with the naked eye?

  16. ChuckyD81 says:

    All…
    For the last couple of days there has been this West-to-East streak of what appeared to be high cirrus clouds. Interestingly enough you couldn’t really see it in the afternoon Visible satellite loops…but could see it during the morning when there was marine stratus well below it. Anyway, I’d been wondering what that was since earlier this week.
    Then, the other day one of you posted a link to satellite imagery that showed remnant Sulfur Dioxide left over from that volcanic eruption in the Aleutians last week.
    Well…the light went off yesterday, and that’s what that plume is on visible satellite imagery.
    Check this link out…it shows it nicely.

    (Note: If you view this link in the afternoon you’ll probably still be able to see it, but not as clearly as you will through the morning hours.)

  17. HIO Phil (Punxsutawney) says:

    Partly Cloudy on the West side this morning. From the amount of clouds making it over the West Hills I’m guessing the marine layer is about 500’ thicker (higher) than yesterday.
    52 at 6:00am which is actually warmer than yesterday, but it felt cooler/moister on the ride in this morning. I’m thinking a bit cooler again today with a high about 80 around Hillsboro.

  18. The Triforce says:

    Guess moms arthertis was wrong then. 😦 I was hoping for some rain out of her pain she had to go through. I wanted something good out of it.
    Please Air God can you make a good wet possibly record wet week next week? Thank you for that thunderstorm that one night even though we didn’t get it as bad as Portland. 🙂 🙂

  19. Looks like all the recent model runs took any precip chances and threw them out, but no intense heating in sight either, just a wonderfully comfortable 75-77F for the week 🙂

  20. The Triforce says:

    Whoops forgot to erase Then KSLE. I am tired. :>

  21. The Triforce says:

    Salem is 54F and I am 56 so I am warmer and Bormier then KSLE. What a minute how did Bormier get in here? He should go back to ME. Out out OUT! points finger towards studio door.
    Bormier slinks out into a time portal somewhere in the parking garage back to ME.

  22. Luvry says:

    Yo, Bdizzy! Thanks for the update TV…I know I appreciate everything the AMS does for all of us weather fanatics, let me know what I can do to help out at any point…I mean, we’ve chased storms together, of course I’m there for you man! I’m headin to bed! Sleep well all.

  23. TV Weather Producer says:

    Props to Mark and Drew who I sat down with this evening at the AMS Executive Council Meeting. Let me just say that there are some excited things going on with the Oregon AMS. If you’re not a member, I highly suggest joining. Its only $7 a year. We will be making the announcement on when the annual Winter Weather Meeting will be taking place. Also look for the meeting where the Vancouver Tornado is discussed with depth. Like I said, a ton of excited things coming down the pipe.

    1st….
