8pm: Thunderstorms Skip Over Metro; Mainly Rain Tonight

8pm Thursday…

Well, if you wanted to see big thunderstorms here in the Portland Metro area…it didn’t happen.  As the strong line of storms moved north, it weakened dramatically.  There was only one lightning strike in Multnomah county and one lonely strike in Clark county.


But then look at what happened as it headed farther north into SW Washington!  Crazy thunderstorms with hundreds of strikes from Kalama north…same thing from Vernonia north in the Coast Range.  In fact Troutdale never even had measurable rain!  On the positive side, at least that avoided a metro commute meltdown from flooding rains.


Look at Salem…almost 1.5″, and there were reports from Albany and Turner of almost 3″.

The severe thunderstorm watch for areas east of the Cascades has been dropped as the big storms moved off to the north.  The largest hail size reported was “golfball” in Bend, but radar at one point showed hail as large as chicken eggs in Sherman County, south of Wasco.

For the rest of the night, it’s a mainly rain event with just a few flashes or rumbles possible.  As the flow turns more westerly, rain should become heaviest on the east side of the metro area.

    What a wonderful day of weather! Clouds, rain, and cooler temps.
    But, by Tuesday my happiness will melt like a Hershey bar on the dash board of my truck.

    At 4:45 PM I was getting ready to post a comment. The comment was that it was so dark outside the lights were coming on and it was as dark as 9:00 PM in early September. The rains were falling as hard as I have ever seen. This includes storms in the midwest and in the south. There was constant lightning and thunder. Then the power went out in our office so I never got to post it. Now 20 hours later I finally will. We had 2.27 inches of rain between 4:00 PM on Thursday and 8:00 AM today. .79 fell between 4:00 and 5:00 PM. Power was out in quite a few neighborhoods. There were hundreds of lightning strikes. Many streets were flooded. Some creeks briefly overflowed, and some basement had quite a bit of water in them. This was a thunderstorm like I have only seen in the midwest or the south before. As they say a storm of a lifetime. Just 3 weeks ago Salem also got hammered by a strong storm with almost 300 lightning strikes. We have certainly had our share of convective activity for one summer. Now I look forward to a late summer warm spell next week. It might hit the low 90,s 2 or even 3 days. 3 days would give us 19 days over 90 for the summer. So we might yet get our 20th day over 90 in Salem this year. Hope you all made it through the big storm ok. Peace.

      We saw several bright Lightning flashes and VERY loud thunder here in Silverton that almost rattled the house but not anywhere near 300 lightning strikes.

      The dome tried to kill the storm but the rain eventually kicked the dome out of here and it poured like the dickens for about an hour then it was steady rain all night long. Yee haw!

      We have the same kind of dome what’s his name up in Portland blogs about but this time I squeezed 2.8 out of the gauge of rainfall! 🙂

      I am not entirely sure if the other guy’s dome broke or not.

  4. W7ENK says:

    Okay Mark, I’m dead serious. I want an explanation. Technical, scientific, whatever, I can handle it.

  5. David B. says:

    As I expected, the thunderstorms all fizzled as they left the Cascades and entered the lowlands. At least none of them made it here 😦 . Still got a respectable amount of rain overnight, though less than you got to the south.

  6. chiefWright (Marquam) says:

    Long, steady rain last night. Was feeling pretty proud of 1.24″ in the bucket until I saw the 3 & 4″ reports from N. Linn & S. Marion counties this morning! That’s a big help to farmers getting their fields prepped for winter.

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

    Rainy, Dark, and a SW Wind on the way to work this morning,

    Feels like fall/winter.

    Other than it’s 20-30 degrees too warm.

    1.25″ as of 5:30 this morning at my station since midnight Wednesday. Already at my September monthly average.

    Pouring here at work. I’m thinking the last few days have put a serious dent in the fire season, especially for the Washington Cascades.

  8. runrain says:

    I don’t know why, but I think it’s that gorge that messes us up from getting the exciting weather. Prob also responsible for making PDX one of the more bumpy places for landing aircraft.

    • archangelmichael2 says:

      I bet pilots have a fun time landing there. Ever tried to land on Flight Simulator using real time weather?

      freggin spam ^ — sorry… find a new place to post this crap…. Interesting… but old. (Mark… yeah.. it’s cool info… but not a blog post? — it’s become more like a spam posting…)… maybe you should give Brian a slot to post it in the side bar?… — It’s not a “discussion” item. (pure and simple)

    • archangelmichael2 says:

      That would be cool. A sidebar showing the most extreme conditions of Oregon.

    • Timmy_Supercell (Klamath Falls @ 4200') says:

      I like the info. Don’t know what these yahoo’s are saying Brian. Keep going 😉

    • AdamInAumsville says:

      Closing in on 4″ in the last 24 hours here.

    • MasterNate says:

      I enjoy knowing the extremes Brian. I appreciate you posting them. Just ignore the negative feedback.

    • gidrons says:

      Keep posting Brian

    • W7ENK says:

      Snodaze, lighten up. This is good, relevant info, and most people here appreciate it.

      Thank you again Brian for posting the daily extremes. Very interesting info!

    • jake at blue lake says:

      and snoedaze post is soooo much more on topic? i would much rather see weather info posted on a blog vs hate posts and attacks on other posters..smh

  10. Taylor says:

    Well we didn’t get thunderstorms in the Portland Metro area, but the heavy rain is heading south from Washington towards here. So at least we get into that action a bit.

  11. Brian says:

    I think the Mcminnville airport rain gauge is broke. I had .61 inches of rain about 7 miles north of Mac and got soaked in Mac when the line of heavy stuff finally moved in around 5:30pm. Looking at the radar history I find it impossible that they only got .02 inches unless there is a highly focused energy dome over the air museum and airport.

  12. P.S.C.Z says:

    Here they comes

  13. Taylor says:

    Looks like the heavy rain is starting to shift and heading south towards the Portland Metro area.

  14. AdamInAumsville says:

    Eclipsed 3″ of rain for the day.

  15. snodaze says:

    painting by numbers would be hard to do in Oregon and Washington?

    sadly everything seemed to “skip” over the metro area… — I asked mark “why”… We’ll see if he answers? — it would be good TV imo…

  16. pappoose in scappoose says:

    Don’t know if I’m just not used to seeing rain this time of year or what, but the amount of moisture I’m watching on radar, coupled with the direction it’s coming from, is a bizarro world moment for me, really weird!

    • Longview - 400 ft says:

      Even now at 12:45 am is still yellow/orange moving North to South from St. Helens, Oregon up North to Marysville, Washington. Yikes, WOW, and utterly amazing!!!!!

  17. Organized line of strong convection about to engulf easy side metro SEA

  18. Joshua in Lake Oswego says:

    Round 2 incoming. The north east areas are going to score.

  19. BoringOregon says:

    Maybe we might have Some good, T-storms next week. With things heating up at the end of the 7-Day ??

  20. P.S.C.Z says:

    Frequent Lighting with Thunder roaring in the background

    • David B. says:

      Rain just starting. Thunder/lightning seem to have diminished a bit. Hopefully it won’t be another tease. I’ll find out soon enough.

    • P.S.C.Z says:

      Check out Radar Wow never seen so much dark red heading right for us. Don’t give up on that Thunder Lighting it’s a coming

    • David B. says:

      Maybe headed for where you are but not me. Looks like another fizzle for B.I. Just a bunch of generalized light rain headed here.

    • P.S.C.Z says:

      Don’t give up It’s coming give it a few hrs should be rocking and rolling on Bainbridge

    • David B. says:

      Most of that red and orange is over the Cascades. I’m of the opinion it will fizzle as it gets to the lowlands. I hope I’m wrong, of course.

  21. archangelmichael2 says:

    If we have a lot of cold air bottled to our northerly friends this winter but NOT much easterly components could we still have unusual snow events below 500ft if the weather systems are strong enough from a powerful 300kt jet?

  22. archangelmichael2 says:

    Since we seem to lack easterly winds in recent years during the winter I reckon we will have tons of very cold *zonal* flow type cold fronts come thru if the air to the north is at unusual levels due to the major jump in ice from last year.

    Not sure how well the low lying areas do with cold zonal flow type systems without an easterly component but I imagine anywhere from a dusting to an inch?.

    • David B. says:

      As thousands of investment prospectuses say: “past performance is no guarantee of future results”.

      Before this recent drought of strong arctic blasts kicked in, we had a string of winters with one or more of them. That didn’t make arctic blasts happen in all winters thereafter, did it?

    • archangelmichael2 says:

      That’s not what I asked.

  23. P.S.C.Z says:

    we are just about to get hit by a VERY INTENSE line of Thunderstorms. Let the party begin.

  24. Longview - 400 ft says:

    So weird to see the moisture come from the NE instead of the West or the usual South West.
    I have heard thunder all evening and it looks like it will be around through the next hour. I have never seen so much yellow from the North East since a I have been observing radar. WOW!!!

    • Muxpux (Castle Rock 175') says:

      I’m in castle rock and there are some intense strikes. If less frequent

    • Longview - 400 ft says:

      The thunder has kind of been all around us down here. Only a few directly overhead.
      It looks like heavy showers were you are at for quite awhile.

    • lilfoot123 says:

      This storm is cycling back through from the north so crazy! Very heavy rain! Cats are not fans of thunder! I’m not high enough to see the strikes just the cloud to cloud strikes & hear the thunder! Wow almost four days in a row I’d this loving it!

  25. Very active lightning to my ESE moving in. Wow

  26. Marcus the weather nut says:

    Portland u may be in luck the northern half of the storm is heading south….. Some heavy showers embedded may still be hope……..

  27. carnyfriday says:

    Pfffft! Wanted thunder and lightning!

  28. Wendy-Silverlake, Wa says:

    Still thundering like crazy. A few are rocking the house. Almost an inch of rain in the last couple of hours.

  29. Marcus the weather nut says:

    About to get soaked her in LC….. Maybe a rumble or two I see some yellow and orange on the radar;)

  30. W7ENK says:

    How in the actual mother fracking fark does this even happen??? I sat out on my neighbor’s front porch with their three grandsons, two of whom started Kindergarten yesterday, none of them has ever experienced a thunderstorm, and we sat there for almost two hours just watching it rain, waiting for the sky to light up and start doing something impressive, and it failed. Nothing happened. Not a God dammed thing! Hell, I hyped this up so much for these kids, one of my neighbor’s grandsons was so disappointed, he started crying. No wait, that was me… Regardless, this was probably the worst, most unfathomable bust I’ve ever had the displeasure of experiencing. I couldn’t even begin to wrap my mind around how unbelievably lame that was.

    I hope you all believe in my silly little dome now. It’s always been tongue-in-cheek, but really?? I mean frikkin REALLY??? How? HOW?!?

    I’m done ranting.

    Un-fudging-believable. 😡

    • I’m with you dude, im pretty frustrated myself not a single thunderstorm in the last few days 😦

    • Looks like the back side may slide down over PDX. You may get a few exited electrons yet.

    • High Desert Mat says:

      I feel your pain Erik. I mean I don’t, but I understand. Un believable how it fell apart right about Woodburn or so. But on the bright side u did get one huge epic event in late ’08 with that unforgettable snow to ice to snow to ice etc. Storm. Honestly, I think everyone will be happy after what this winter has to offer all of us. My prediction, PDX gets more snow this year than Redmond Or. I think we’ll be alot colder overall of course but Portland will have more snow by winters end. Just a hunch. Mark my words come March tho.

    • High Desert Mat says:

      And anyways, summer isn’t over, look at next week, it looks beautiful and warm. Cherish it while we can cause we all know what’s right around the corner!!!!

  31. Aleta- West Gresham says:

    Weird looking on the radar. A few showers in the metro area but for the most part does look like a dome over the area!

  32. Closing in on 3″. Might as well go for it! Still raining……….

    • Albany looks like ground zero for this event! The river levels are shooting up and it looks like the Willamette at Salem may reach an all time high tomorrow.

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

    3 reports of golfball sized hail, in Malheur County, Morrow County, AND in Deschutes County. Plus a tornado warned Supercell east of Heppner. And Oregon/Washington being totally raked by lightning.

    Overall, EPIC event! I would have never guessed this would happen on a September day. Certainly late in the year for this sort of thing, right? 😉

    • Timmy_Supercell (Klamath Falls @ 4200') says:

      Oh and, not to mention all those floods in the central/southern Willamette Valley, as a huge squall line of convection extending from the coast to the cascades pushed northward. A textbook event we haven’t seen since 2009. Although just without better dynamics to kick up stronger storms with severe characteristics west of the Cascades. And without the SVR Watch… but still awesome!

  34. Top of Mt. Rainier forecast:

    Tonight Snow. The snow could be heavy at times. Some thunder is also possible. Low around 25. West wind 8 to 10 mph. Chance of precipitation is 100%. Total nighttime snow accumulation of 10 to 14 inches possible.

    Friday Snow. The snow could be heavy at times. High near 34. West southwest wind 7 to 10 mph. Chance of precipitation is 100%. New snow accumulation of 9 to 13 inches possible.

    Friday Night Snow likely. Cloudy, with a steady temperature around 26. West southwest wind 7 to 9 mph. Chance of precipitation is 70%. New snow accumulation of 2 to 4 inches possible.

    Saturday A 40 percent chance of snow showers. Partly sunny, with a high near 36. Southwest wind 3 to 5 mph. New snow accumulation of 1 to 2 inches possible.

  35. Tyler Mode in Battle Ground says:

    0.27″ here and it has dropped below 60 now. :). I’m ready for some cool crisp nights!

    Not one rumble heard here today, I guess it’s payback for the show the other night!

  36. pappoose in scappoose says:

    “Total predicted rainfall for the 15 hours ending 3 AM is shown below. 1-3 inches over SW Washington and northwest Oregon. And it is not over at that point.”

    “The big rain is coming in TONIGHT.”



  37. oldwxwatcher says:

    Kind of like the last two winters. Snow all around but none to speak of in the city. Ditto for thunderstorms, it seems.

  38. What an interesting event. Albany went off the grid a few hours back with 2.85 in the bucket. Wow.
