Thunderstorms Popping Up

Some thunderstorms right around Multnomah Falls, east of Sandy and headed towards the Central Columbia River Gorge at this hour.  There are more storms down around Detroit Lake, also headed north.  Another warm and humid day out there with temps right around 70 even with the thick cloud cover.  A good soaking coming up the next few hours.  Thunderstorm chance not real great down here in the lowlands with no sunbreaks, but a moist southerly flow can always surprise us (in a nice way!).

12z WRF-GFS showed some very heavy rain this evening; we’ll see if that comes to fruition.  Our RPM model showed more of the scattered showers that we are seeing now.

    Looks like I gotta keep the windows open tonight once again… Still feeling a tad muggy and dewy out there. Let’s get some storms tomorrow!

  2. Timmy_Supercell (Hillsboro) says:

    There is a really good looking thunderstorm in north central Oregon right now. A storm just off of I-97 has VIL readings going near 50 kg/m2 and echo tops of well over 30,000 feet. Not sure if these level 3 radar readings are just over-exaggerating this cell, but this may require a warning or two.

    I’m in Bend this evening, and just spent the past 90 minutes watching a lot of lightning with thunder. At times, the lightning was flashing every few seconds. Nice stuff!!!

  4. Rob "Wrath" S.E. Portland says:

    Storms don’t want to give up over north central Oregon.

  5. Josh "The Snowman" From Everett, WA says:

    How’s everyone doing?

    I’ve made a couple of posts, but wanted to re-introduce myself as I’m here for the winter fun!!!!

    Gonna be a good one, I got some inside information about it.

    More to come……

  6. Battle Ground Brian says:

    Picked up 0.43″ here between 5 and 8pm

  7. davic says:

    when will the rain stop? will we have a nice weekend?

  8. Kyle says:

    HOWEVER the information is presented in an unique prespective and they are almost always right it seems from their archives………especially in the later years when they’ve got it down.

  9. Kyle says:

    Has anyone ever visited Mark’s Nelson’s “uncle blog” called Capital Weather Gang for the east coast? (Washington DC and the mid Atlantic)

    They used to have their own address called ironicly enough in 2004:

    Now they merged with the newspaper over at

    Unfortunatly the bloggers are a lot more biased on climate change views then here and you’ll get chewed out sometimes if your views differ.

      We here in the PNW tend to be a little more ‘open minded’ when it comes to sensational or controversial topics, especially if said topics have any religious overtones. The rest of the country, not so much. This was evident when I visited a friend in Ohio last July. I tried explaining my anti-organized religion less-than-Christian nature-oriented borderline pagan idea that the Great Outdoors is my church and God is everywhere and in everything concept to some of my friends’ friends — they looked at me like I was some sort of a Devil worshiper. I guess I should have expected that in the Bible Belt. o_O

      But, I digress.

      It’s still MUGGY!!! 😦

  10. Tyler in Hazel Dell says:

    Seems like a decent “line” has formed as it is moving out of Portland. Distinct back edge down to the south though!

  11. Yevpolo1990 says:
    Still have a nice chunk of 35-40 knot shear over a good Portland area. I hope it doesn’t all go to waste…

  12. Kyle says:

    Thanks Rob for clearing that up.

    Just had heavy downpour for 5 minutes which I was caught in it. 😮

  13. Yevpolo1990 says:

    I think the system behind the one that is west of us will bring much more of a southerly component and move the moisture more towards our area, rather than SSW/SWS flow that we have had today.
    Any thoughts?

  14. W7ENK says:

    66.6F 96% RH… sticky icky!!!

    • Kyle says:

      :p You said it! Looks like another *short* AC night coming up.

      And it isn’t even a true “heatwave”. 😦

  15. chiefWright says:

    Riegonal radar shows there’s a well defined back edge to this mess. Unless there’s something stronger out there, I’m guessing we’re out of the woods in a few hours.

  16. WeathermanRob says:

    It’s already snowing in ND… about an inch fell this evening.

    • Rob "Wrath" S.E. Portland says:

      Is that you Mr. Martin? Is that early for snow?

    • Garron near washington square says:

      I was just talking to my grandma in Dickinson ND. I don’t think she can ‘mentally” take another ND winter, and that’s saying something!!! She’s lived there for most of her 90 years. It’s 38 there currently with “wet snow”. She said that there is a nice coating of snow in the grass, and sides of the road already, and that they are calling for a killing frost tonight with lows around 28.

    • Garron near washington square says:

      current update from North Dakota…31 d/f, snow fog and 3 ” on the ground…

  17. Rob "Wrath" S.E. Portland says:

    Instability axis has veered a bit and has backed off the Cascades towards the valleys.
    I think due to this we could see some sporadic strikes closer to the Foothills.

  18. Kyle says:

    Your funny Rob for answering my T-storm cancel card question in a second person way. 😦

    That’s life for me.

    67F and thick as your homemade gravy cloud cover. :p
    Dewpoint is 61F which is mighty high.

    P.S Life will you please stop choosing me as your special target to make me feel stagnated especially weather wise?

  19. W7ENK says:

    I don’t know if this link will work for everyone, but here’re a bunch of photos of the aftermath from yesterdays tornadoes in Central Ohio.!/album.php?aid=2065469&id=1125544241&fbid=1449415431797&ref=nf

  20. Washington Observer says:

    Must have been a good rainstorm on Mt Adams. Creeks are high and muddy.
    A hiker died up there this week. They had turned around to go back down because the weather didn’t look good.
    One of them slipped and fell.

  21. PaulB/Eugene says:

    Juicy looking band of precip approaching Eugene from SSW…

  22. chiefWright says:

    Mark, your bobbing & weaving on the live radar feed is making me seasick…

  23. DEL X V says:

    Thunderstorm in progress south of Mt Jefferson. Lightning visible from vicinity of Redmond in central Oregon. Hope this is not a duplicate posting.

  24. chiefWright says:

    Mark, you know anybody at Timberline that can swing a webcam to the south? Looks reasonably clear and might get a great view of that brew-up.

  25. Yevpolo1990 says:
    Updated shear^
    Looks like some small shear is developing to the southwest of our area

  26. DEL X V says:

    Thunderstorm in progress south of Mt Jefferson. Visible from near Redmond in central Oregon….Frequent lightning.

  27. chiefWright says:

    Cute comment on the live radar feed, Mark!
    Definetly getting nasty out there– Near Olallie? Timothy Lake?

    • Rob "Wrath" S.E. Portland says:

      Just southwest of there. I’d guess this is moving right over/near Harriet Lake.

    • Garron near washington square says:

      I saw that!!! That’s hillarious. He’s playing with the radar right now…keeps moving it around.

  28. Rob "Wrath" S.E. Portland says:

    😆 Mark wrote “Good Afternoon Geeks!” on the Fox12 Live Radar 😆

  29. Rob "Wrath" S.E. Portland says:

    Zoomed Radar

  30. W7ENK says:

    Everything is calling yesterday’s event in NY a tornado, but all the video evidence I see (so far) is showing just a heavy squall line…

    Maybe we’ll get some of this later??? :fingers crossed:

  31. DEL X V says:

    I believe Mark talked about the threat of NW Oregon thunderstorms for this afternoon in his on line discussion a couple of days ago….Nice job!

  32. Rob "Wrath" S.E. Portland says:

    Winds aloft are starting to increase a tad with the big storm over southeastern Clackamas County. Also a small hail core showing.

  33. Garron near washington square says:

    Man, that is interesting. I was just looking at the fact that it’s clear and dry in Madras and Bend, and thinking how impressive that push of moisture on the WV loop looked. It’s no surprise I guess that with the higher temps east of the mtns that we would see something pop up over the mtns. NOAA is calling for just shy of 1.5″ Sat-early Sun with the next push forecast to go over us instead of dragging due north.

  34. Ryan (Walnut Grove) says:

    Looks like most the storm activity is staying in the Cascades or just to the east of the Cascades. Hopefully we get a surprise but I’m not overly optimistic.

  35. Rob "Wrath" S.E. Portland says:

    Mark, thanks for the update. We just need the flow to veer a bit more. Probably though may be lucky to see some flashes over the Cascades this evening.

  36. W7ENK says:

    I haven’t seen or heard anything… yet.
