A Busy Weather Day: Thunderstorms & A Waterspout


As expected, thunderstorms and hail showers are moving across the western part of Oregon & SW Washington too.  That’s due to a chilly airmass overhead but we still have relatively warm temperatures down here where we all live.  That means lots of rising motion in the atmosphere = thunderstorms.

Note the 1st fall snow up in the Cascades…Timberline Lodge this morning:


One thunderstorm produced a waterspout just offshore of Happy Camp (between Netarts Bay & Oceanside).  IF that would have moved onshore, it would be a tornado.  Remember Manzanita last October?


Of course many of you are seeing thunder and hail right now as a cluster of action moves over the Portland Metro area.  This will continue through the afternoon, of course interspersed with sunbreaks too.  Classic spring, or fall, weather.  Enjoy the change and by the way, enjoy the fresh air!  Particulates in our air this morning were so few and far between they could barely be measure…all of 8 on the AQI:


Stay safe this afternoon while driving through downpours, we’re out of practice with our rainy driving skills…


That’s the 12:40pm radar image here in the metro area, looks like Sherwood and Newberg getting the action, but the cells will continue moving to the east/northeast.

    Mr. Nelsen, when are you going to put up your outlook for the fall/winter 2017-2018?

    In a couple days we go back to some nice, warm and benign weather. Just a wake up, folks!
    “Winter’s coming”!

    The sky is falling it’s absolutely storming outside. Checked NWS map and it’s shows a special weather statement for thunderstorm in the foothills east of Estacada and Sandy.

    I’ll bet Timberline is closing in on a foot of snow. Heavy thunderstorms rolling through here with torrential downpours. Viva La Nina numero dos!!!

    Something obviously tore through my neighborhood yesterday afternoon.

    My corn was flattened,

    My hops were knocked over,

    I also had a decent sized branch come down out of one of my trees.

    0.06″ of rain Sunday,
    0.66″ of rain yesterday,
    0.12″ of rain overnight last night.

    0.84″ since this rain started, and it’s been raining pretty much all day long today, so however much that adds by tonight…

      Bummer. What do you grow the hops for, Eric? Beer, I guess? Hope you can salvage some of your crop …

    Mark, 2 cat 5 Hurricanes nearly back to Back…seems like weather is getting really mean..I think those areas that were ravaged should not be repopulated..what will people do when the day comes and the water does not recede?

    I feel bad for people losing there homes, but I can’t feel bad if people move back and lose everything all over. Some where it needs to end.

    • W7ENK says:

      Lee, I don’t think you fully understand the ramifications of what you’re saying. We’re talking about entire, sovereign, Island Nations here. Islands that are entirely their own, self-governed countries. What, are you proposing that they just give up entirely, forget about their governments, their land and their citizens? Two big storms, walk off their islands and call it quits?? How would you feel if the United States government just said “Welp, that’s too many disasters for us, we’re done! Y’all can go live somewhere else now…”?

      Do you actually get that, Lee???

    • By that logic, any place at risk of a catastrophe should be depopulated, including the PNW west of the Cascades. It’s not like those islands are regularly hit by such extreme storms. If they were, nobody would live there.

  7. Lee Wilson says:

    it is hard to believe 2 days we went from summer to winter like conditions …fast weather change..I await to se what winter brings..we better get ready, were in for a fun ride 🙂 YEEHAWW!

    Definitely time for a safe driving reminder…..roads are layered with slick residue from months of traffic without rain!

    I live in Vancouver at SE 177th and Mill Plain. While sitting on my balcony Monday evening at 9 pm, and although I could not see it, I could certainly hear a car traveling on Mill Plain at a VERY high rate of speed.

    I thought “wow that’s way too fast”……..

    Then I hear a long, drawn out skid. Tick, tick, tick, tick, tick, tick, SLAM. Reached for my phone halfway through.

    The impact was incredibly loud, sounding like an epic thunder clap, as the car collided with whatever it was trying to avoid.

    Immediately called 911.

    What can we learn from this?

    Be SAFE, not STUPID

    P.S. What am amazing photo of the waterspout! Kudos Jim Young!

    Crazy day! Better than I expected. Had a good hour of thunder and lightning at work in Tigard between 1230 and 130. I live in Newberg. Recorded a total 0.18″ at home and saw a good roll cloud on the way to work.

    Yes I know 0.18″ isn’t impressive.

      Customers in Dodson had their spring system destroyed by Eagle Creek wildfire. Fortunately they drilled a well back in 2004 as a backup. Was able to get there well pump running just in time for supper. When we shut off the work truck we could hear rockfall due to the unstable terrain. The Gorge burn is really a sad sight. I don’t believe it will ever be the same Gorge again. Some basins have no green tree left. The magnificent towering pinnacles at Dodson that had stands of timber at the very top were even burned up. You’d think these would be isolated towers of protection but unfortunately they too burned. Really a heart break it was human caused.

      • JERAT416 says:

        I hope the rain will knock down the fires soon. Is there anywhere I can look up the fire progress? The only places I’ve found to look these up are way too jumbled full of information.

    0.79″ here for today. 1.42″ is the storm total so far. Air is very refreshing.
