Hockinson Tornado Video

This came in late this evening from a viewer.  Jason Williams lives right beside the field the tornado ripped through today.  It appears to be the end of the event.  At the very beginning of the video you can see a leftover circular motion to the aluminum roofing flying across the field:

    At least someone had some action. Here in Beaverton, and where I work in Parkrose, it was just rain, hail, wind, sun, clouds, and such. No snow, no tornado, no thunder. Something to talk about at least!

    That meteor/fireball that everyone’s been reporting on the East Coast was really just Georgetown basketball going down in flames. Holy moly!!

  4. W7ENK says:

    Okay well, the Dome was only down for all of three minutes. I think a little bit of weather accidentally leaked in through the hatch when the NWS was climbing through to perform some maintenance. 😦

  5. W7ENK says:

    Holy CRAP! It is currently snraupailaining under the dome!!!

  6. Last year on this date I woke up to 9-1/2″ of snow on my deck.

    • Garron near Washington Square says:

      That is just awesome, and truly, maybe a once in a lifetime event here for that late in the season. My grandma’s in North Dakota, and would just love to see what a deck looks like without snow on it. It’s been a very cold month, normal highs in the mid 50’s. They are lucky to hit upper 20’s and lows below zero. Last year it was in the upper 70’s back there.

  7. *BoringOregon* says:

    We have had so much hail the past 5 days in a row that I never remembered seeing so much hail before. And we just had a snow shower go by that lasted about 2 mins lol, strange weather week wonder how many tornado’s the mid west is going to have this weekend from this system?

  8. Perhaps a dumb question. But is it possible that yesterdays Tornado was a micro burst?
    Definition:
    A micro burst is a small, very intense downdraft that descends to the ground resulting in a strong wind divergence. The size of the event is typically less than 4 kilometers across. Micro bursts are capable of producing winds of more than 100 mph causing significant damage. The life span of a micro burst is around 5-15 minutes.

    • although that now seems to large of an area. 4km. I thought they could be even smaller and more localized than 4km

    • W7ENK says:

      Microbursts don’t rotate, and in the video above you can clearly see counter-clockwise rotation.

    • Dave in South Salem (500') says:

      I’ve been in a microburst before in Colorado in July. It had an enhanced effect with hail blowing down hard. Not even close to the power of a tornado though.

  9. W7ENK says:

    Yes, it’s graupeling at the waterfront in Downtown Portland. o_O

    • runrain says:

      It looks like there are some MAJOR hail shafts to the west…probably right over the dome!! Hurry home, Erik!

    • W7ENK says:

      Just got home. The ground is dry, pavement, grass, everything. It doesn’t look like any precipitation fell here today. Nothing in the rain gauge, either.

    • W7ENK says:

      Aaaand… no sooner do I say that, it starts drizzling. I see the bulk of the cell just to my South, maybe only a mile or so. Broken clouds and patches of blue sky to my North.

  10. Longview - 400 ft says:

    The last two days here have been interesting. 4 times now I have seen snow, graupel, hail, and in between, all in a shower of precip with temps all in the lower 40’s. I have had gusty winds that I am sure has made that happen.

  11. Jordan (Raleigh Hills, 420') says:

    Looks like snow/rain mix on I-5 at Going right by downtown via the streaming video from tripcheck: http://www.tripcheck.com/popups/Cam.asp?curRegion=16&camera=561

    can anybody confirm? pretty cool. some heavier showers coming in right now. thinking maybe some rain/snow mix this afternoon for some of us.

    • Jordan (Raleigh Hills, 420') says:

      looks to have calmed down a bit, but i’m nearly certain I see snowflakes on there, it was quite heavy a few minutes ago.

    • W7ENK says:

      I can confirm for you that is most definitely NOT what you saw. I’m downtown on the waterfront, only about a mile or so from that camera, and there hasn’t been any precipitation here since… well, yesterday morning. Maybe some last night, but I’ve been here since 6:30 this morning and it’s been completely dry. Besides, it’s currently 44 degrees.

      Perhaps you saw some blowing petals from fruit blossoms? There’s been quite a bit of that this week. Closest thing I’ve seen to snowflakes all year.

    • Jordan (Raleigh Hills, 420') says:

      yeah. it was def graupel or snow. I had graupel and light snow yesterday from a quick hitting heavy shower in Raleigh Hills (temp ~40F).
      Radar had some heavy returns right over I-5 at Going at the same time I was seeing the graupel/snow… it was definitely precipitation with wet streets as evidence… thanks for the input though!

    • W7ENK says:

      I dunno, I’m just telling what I’ve seen with my own eyes. I work with my back to a window, all I need to do is turn 180 degrees from my keyboard and I can see out over the waterfront and the Hawthorne Bridge from three stories up. The roads are completely dry right around here, and the sun has been shining through off and on all day.

      Though right now the sky is getting dark and ominous, and it looks like it may have just begun to sprinkle… No wait… look at that, it’s graupel? Okie dokie!

    • Tim Williams says:

      Interesting W7, I’m working next door to the Marriott and it’s definitely been a rain/snow/graupel mix for the past 10 minutes or so

    • W7ENK says:

      Yes, there was. It seems to have stopped now. Sky is still dark.

    • w7, your back is to the window – so perhaps it was a quick shower you missed. can happen.

    • W7ENK says:

      I look quite frequently. Being the weather geek that I am, I just can’t help myself, especially when the chances of something exciting are heightened! 🙂

    • Jordan (Raleigh Hills, 420') says:

      Headed up to Council Crest for an afternoon walk and was greeted by some nice precip. It began as nearly all graupel and rain, eventually transitioning to all snow. There were some big flakes – quarter size. and pretty wet. But after about 30 minutes had a light dusting on the car. fun times. wish I had a camera with me.

    • Sifton says:

      The nerve of some people huh W7ENK?!?

    • ocpaul says:

      I was driving over Sylvan at 1:00 or so. Had a nice shower of snow/graupel. Sadly, the best snow I have seen this year.

  12. vernonia1 says:

    even @ 11am with full sun…truck still has snow sliding off of it. Snow on the ground is mostly gone & hummingbirds are at the feeder Must be Spring

  13. Sifton says:

    Lol!! That’s a well disciplined young man there, give him another Ma!

  14. ashley watson says:

    Hey cagvic that lives in sandy or anybody else do you have snowfall data for sandy for the last 2-5 years?

  15. With an average temp of 39.3, yesterday was the coldest day of the month so far.

    Bring back the 60s!

  16. Mr. Donut says:

    Check out the PSCZ – it’s goin’ off! 4″ of snow at my parents’ house SE of Everett and dumping hard.

  17. cgavic says:

    At our house, at 1, 100 ft, it’s snowing moderately.

  18. Alohabb says:

    Extremely dense fog in Hiilsboro. Very low visibility

    • Punxsutawney (aka HIOPHIL) at work by Sunset High elev ~280 says:

      Wife reported that our deck in Hillsboro was turning white with the last light shower. Appears to be mostly small grauple with some snowflakes mixed in.

  19. Snow here again in BG. Nothing major of course, but another one to chalk up for March.

  20. Alohabb says:

    Snowing in Aloha.

  21. runrain says:

    We have sunshine poking through…and big snowflakes! Not sticking, but there is a dusting on the rooftops of the homes at the top of Mt. Scott.

    • runrain says:

      Coming down big time now but barely sticking and skies are clearing again. What is it about March 22? Two years in a row of snow!

    • W7ENK says:

      90 degree seasonal phase shift. Welcome to New Winter! Only 3 more months of cool/wet weather before the sun finally comes out and warms us up! By then, the days will start getting shorter again, and we’ll only have to wait another 3 short months for our warm/dry summer!

      Here we go, again… 🙄

    • Mark Nelsen says:

      I had .5″ at 1,000′ here this morning.

    • same here. .5 inches and snowing/snrain off and on all day. 39f the high so far and drops to 34-35f when showers are over me. Nice fat white flakes.

  22. David B. says:

    Snowing lightly in the hills just east of Downtown Seattle this morning. No accumulation.

  23. Regarding the fauxnado… Looks like a glorified eddy, the kind in the fall you see where the leaves start blowing around… I get it… Eddy beneath a 5 mile radius of a convective cloud meets the WMO definition of a “tornado”. By that definition, we might live in a tornado alley! Time to build a shelter

    • SEATTLE NWS *URGENT MESSAGE*
      Pedestrians have spotted and reported a vortex curbside at the corner of 4th and Pike Street. Visual analysis indicates this vortex is heading east, at 3 mph. This vortex has the potential to cause nuisance to persons, such as: inability to light a tobacco or marijuana cigarette; disruption of newspaper reading, causing unintended page turning; distraction while walking on sidewalk. Based on observed track and speed, this vortex should impact the corner of 5th and Pine St in 3 minutes. PREPARE! TAKE ACTION IMMEDIATELY!

    • runrain says:

      Ha ha! Take care! Remove glasses! Tie down all loose objects!!

    • Mark Nelsen says:

      I assume you’re joking? Note the large piece of the roof (a thousand pounds or more) lifted up, carried mainly intact, over a fence and into a field with very little debris on the way over. A little eddy couldn’t do that.

    • W7ENK says:

      A little eddy couldn’t, but a big eddy could, especially the kind that dropped out of the bottom of a cold-cored convective cell!

      I can definitely see rotational winds in this video. That’s exactly what passed over my neighborhood in May 2009 and took down a stand of 60-80 foot tall cottonwood trees. Despite my video, multiple eye-witness reports of a spinning funnel on the ground, and a 1/2-mile path of damage with clear and consistent evidence of rotating winds at least 100 yds wide, the NWS said no. I even drew them a nifty little map and everything!

  24. 31.5F and snowing again. Spring? It’s a PDO thang!

    Just a dust devil without dust

  28. Gabriel says:

    I had a intense hailstorm today in Salem I got it on video but to see this just wow.

  29. Timmy_Supercell (Klamath Falls @ 4200') says:

    That is undeniably a tornado; when pieces of a roof are flying around across that field while nearly no wind is going on at this guys house.

  30. bgb41 says:

    I can see the burrito wrapper out in that field.
