EF-0 Tornado Today In Aurora

10:30pm Thursday

Well that was an exciting afternoon!  We started with a steady soaking rain this morning, then went into a sunbreaks/showers pattern the rest of the day.  As expected a few thunderstorms popped up along with the usual hail, downpours, and breezy wind.  Now remember yesterday we had numerous funnel clouds/waterspouts off the coastline and up in Puget Sound.  Today some of that spinning energy decided to touch down in the Willamette Valley.

This was a weak tornado, even by Pacific Northwest standards.  It was weaker than the Lacomb tornado last month.  But it still flipped two planes at the Aurora Airport and damaged a bunch of greenhouses nearby.

This is also the only tornado I’ve seen pass close to an official observing site.  Check out the observations from the ASOS sensor near the southern end of the airport:

A couple of things to notice.  First check out the wind shift.  From gusty southerly just as the twister passed by, yet you can see how localized wind is with tornadoes.  Then notice the peak wind gust was only around 30 mph at the sensor which is maybe 1/2 mile south of the tornado path.

This will rank on the low end of tornadoes around here.

I missed all the excitement because I had the day off.  I was taking a run up the road with no cell service from 3:45 to 4:30.  Came back to a whole bunch of texts and warnings.  But with all this weather fun I had to come in of course.  That’s one benefit of your hobby becoming a career.  It’s all the same to me.

Looking ahead, we still have a nice and dry weekend, the rain returns Tuesday.  Enjoy the briefly dry weather!

    October days like these are so fleeting, that’s what makes them so rare and filled with beauty, I can’t hardly wait for sunrise so I can venture out again.

    Beautiful day to go track up some powder. Timberline is already up to a season total of a whopping 67″ of snowfall!

    Nice hard freeze this morning, 30 degrees currently. Those of us farmers have to prepare for this kind of overnight temperatures by judging the conditions the previous evening…..the weather service generally does not seen to foresee these early cold nights for rural areas. Just something we get a second sense for and prepare accordingly. (I see Colton is down to 28 right now).

    • Jason Hougak says:

      I agree
      I haven’t even seen them issue a frost advisory or freeze advisory. Last night was my first freeze and I’ve had three or four frosts.

    this was the video I ws trying to share.

    Mark, It would be nice if we could do Direct Uploads. It also would be benificiial in guaging weather data, some times things just happen and they were not forcasted.

    If we had a way to upload, you could then take the best of the best and put them on air, or keep the archived to see how acurate the predictions were in hopes to Fine tune things a bit.
    Sorry about the Youtube in the back ground..
    Droid messed up and recorded the video, normally it shuts YouTube Down this time it didn’t?

  8. Lee Wilson says:

    Eh Correction, clouds coming in from the North then it turns and goes east..Freaky…..I remember some years ago simimilar weather patterns and we wound up with an arctic blast.

  9. Lee Wilson says:

    about 15 minutes ago, it got dark, then we got blasted by a powerfull wind about 30 mph it lasted for about 5 minutes
    The sky to the east is very dark, and we have coulds coming in from the west. we been having sun breaks.
    I recorded the even, but YouTube was playing in the background as I was recording. So it ruined the video.

  10. Jason Hougak says:

    ⚠️️16 day GFS insane almost 12″ of precipitation… Gorge could be a disaster!

  11. Roland Derksen says:

    No tornado here, but this morning the view of the mountains shows quite a bit of snow on them. I’m not very good at estimating snow or freezing levels, but from what I see, the snow level is around 3,000 feet. Haven’t seen it that low before the mid-point of October since the early 70’s. Snow on Halloween?! Probably not, but the way things are going, it’s a possibility for me.(last time it actually happened was in 1984)

    Timberline has Pucci lift scheduled to run today. Friday October 13th and a lower mountain lift is running!

    • Nahtalkin says:

      OK, so glad you are on top of the ski report, I assume many more to come this season. Don’t break a leg!

  13. Mark, is there anything in the works to make it easy to upload pictures or videos to this blog? I take avid pictures of weather and love this blog but haven’t figured out the workaround to upload pictures. An easy icon derived featured would be awesome!

    • W7ENK says:

      Upload to any photo sharing website and comment the URL here. As long as the link ends with a .jpg .png or any other picture file extension, it should load here just fine.

      Google photos is a little less forgiving, I’ve found.

    Don’t you think it is interesting that this is the anniversary of the Columbus Day Storm of Oct 12, 1962? Yes, the tornado did some damage, but nothing compared to the Columbus Day Storm. I am surprised that no one has mentioned this..
