A Nice Summer Lightning Display


Well that was briefly fun.  At least 1/2 of the metro area saw lightning and heard a few rumbles in the distance…a few of you had an excellent show with lots of loud boomers.

From 9:30-11pm thunderstorms fired up in Washington County and then across the south metro down into Clackamas County.  It appears it is most likely over at this point.   This is the radar image from earlier:

The movement was interesting as they were stationary at first and then drifted SOUTH or at least propagated that direction.  It wasn’t the south to north we often see in these summer events.  It appears that was due to us being on the backside of the upper-level disturbance as it passes through Oregon.  I see a couple spots in West Linn & Oregon City picked up around .80″ rain, plus viewer Steve Huffman sent in this pic of 3/4″ size hail in the Farmington area south of Hillsboro


There were also a few strong storms around Stevenson/Carson and the Hood River Valley earlier.  This pic is from Gabor Gardonyi


Unless we get a surprise shower or thick drizzle late tonight or tomorrow morning, it appears this event will leave Portland dry.  It’s back to a major marine push tomorrow, then a thinner marine layer over the weekend.  Summer 2018 rolls on…

    Oops..i tapped the wrong icon…i didn’t mean to log in with my YT? Account lol..ah well.

  2. No storm for us on the 21, but we sure are raking I the power after the clouds left.
    Garden is really taking off.

    “Summer” started early this year and that’s amazing but I have this odd feeling that we are going to get hosed by this pesky “deep marine layer”. Here’s to hoping it doesn’t ruin our actual summer.

      Not to worry, SK. Unless you live right on the coast, the marine layer” shouldn’t be a major factor this summer.

  4. …over here in the grande ronde valley i had the joy of seeing 4 separate cells firing consistantly for hours…one on top of me and three scattered about…a night to remember 🙂 …

      …it’s a beauty way to go…

      Hey Larry, how long are you going to be up there?
      We just might be roaming around and going that direction at some point this summer.

  5. Roland Derksen says:

    Just a very light sprinkle of drizzle here this morning, and skies have cleared off this afternoon. Might see a shower or two tomorrow, but that’s it.

    I see all the twitter buzz! Enjoy weather nerds! Here it is STILL storming outside. Rain totals anywhere from 1 inch in the driest areas to 5-6 inches in the wettest areas (in a two hour time period).

    On topic of the PDX storm, I see reports that Beaverton roads are flooding. Stay safe guys!

  7. Paul D says:

    It’s wet outside! Woot!!

    The visible satellite image is pretty awesome… I’m guessing you all can figure out where our t-storm is centered.

  9. Ryan (Vancouver Heights) says:

    Wow, didn’t expect to see monster floating around this morning. Looks like it is enhancing a little bit as it crosses the west hills into downtown while it drifts ENE.

    Bonus storm.

    • W7ENK says:

      It actually sheared apart as it crossed the West Hills and went quiet. The Northern extent collapsed as the Southern part swung around to the East and the whole storm died.

      Watch it on radar, it’s pretty evident.

      The next cell popping now has some potential.

    Holy cow. Massive thunderstorm just passed through Garden home. Clap of thunder shook the house and not a small picture off the wall.

  11. Ken in Wood Village says:

    That’s funny, I can hear thunder all the over here and there is no thunderstorm next to me 🤗

  12. W7ENK says:

    Very loud thunder to the West of the Park Ave MAX station just now. And I left my umbrella in my car, so I know that if I run to grab it, it won’t rain, but I’ll miss the train. If I don’t, it will dump rain on me the whole walk down to my office…

    • Ken in Wood Village says:

      Lol, get wet…lmao 😂😂😂😂

    • W7ENK says:

      The whole way into Downtown, I was watching lightning bolts slice through the marine layer just on the back side of the West Hills. By the time my train was crossing the TriMet Bridge, lightning bolts we’re hitting the top of the West Hills around OHSU and points immediately to the South. The thunder was so loud, I could hear it while the train was moving. Power in the train cut out momentarily, 3 times.

      The moment I stepped off the train, the storm went quiet. Only heard one distant boom as I walked past the KOIN Tower. Rain held off until about 90 seconds after I walked into my building.

      • Ken in Wood Village says:

        So cool 🤗🤗🤗 I didn’t see any lightning but I could hear the thunder all the over in Wood Village next to Troutdale. I can just imagine how loud it could have been being under the thunderstorms 😉

  13. Ken in Wood Village says:

    Hmmm, interesting. If I remember correctly, I said we could have morning thunderstorms 🤔

  14. Max in Fairview says:

    Getting power glitches/radio acting funny…

  15. runrain says:

    What the heck?!?! A morning thunderstorm marching east across the Willamette!!

    Loud thunder and lights flickering in Tigard right now.

    Last night Aloha got hammered with hail rain and a real bright light show.

  17. K says:

    I’m sorry that those thunderstorms weren’t as…strong as we weather nerds wanted them to be. There are always opportunities I guess throughout the summer. Here in Pune, India, I saw the most impressive thunderstorm I’ve ever seen. It lasted anywhere from 1-3 hours, and I counted numerous flashes. Roads were flooded, as were low lying areas. I have video, and currently it calmed down but has now picked up again with numerous flashes. Apparently 4.3 inches of rain was recorded in one and a half hours. I have video which I will post. As I type this, power just went out too. I love it!

  18. Ken in Wood Village says:

    Well, I was right about having some thunderstorms this evening. Just wish they were closer to me…lol. It looks like we are in another dry spell. Hopefully something will show up for another round of thunderstorms. This time I hope we get them during the day and hopefully over my place…hehe 🙂 First 😉

  19. Jalen Morris says:

    And of course once I leave Aloha, the dome lifts a thunderstorm is born. It is now clear more than ever that I am cursed. :/

    • W7ENK says:

      Welcome to my world. It’s been my curse for as long as I can remember. In fact, I can’t remember the last time I actually had a good thunderstorm roll directly over me.
