Thunderstorms Arrive in Metro Area

7 cloud to ground strikes from the new cells in east Vancouver and Camas area within the last 15 minutes…heavy rain extends from there back to Scappoose, Sauvie Island, and down into central Portland.  Enjoy the show up in Clark County!

    Today we are not going to see thunderstorms, but tomorrow/Thursday could be our next chance as GFS does hint a good deal of instability with our wind/rain producer off shore. And too bad tomorrow’s system will bring cold cored thundershowers since daytime highs go back into the 50’s. But at least its something to chew on given we have already missed two chances the last two days.

    • Timmy_Supercell (Hillsboro) says:

      Heck I didn’t even hear a bleep with yesterday’s “event”.

      Cold cored convection in the middle of May has to be better than nothing if thats all we can get.

  2. W7ENK says:

    It’s lookin’ like the sun might try to come out again today, but the flow is definitely from the West.

    That just takes all the fun out of it! 😦

    Here’s my hail video contribution.

    South Dakota. 3 rounds of Baseball to Grapefruit sized hail. Then around 3:00 mark looks like a funnel moves right over his house. The guy makes some funny comments too! (He might be drunk?) 😆
    He does swear once I believe….

  4. Battle Ground Brian says:

    Here is my theory on why there were local downpours in such a small area tonight. A somewhat rare surface wind convergence around 5-6pm tonight caused a narrow zone along and just north of the Columbia River to set up. This is similar to the PSCZ in the Seattle area.

    I have created the following map depicting how narrow this band was based on 8 hours of radar returns.

    • Rob "Wrath" S.E. Portland says:

      Agreed. You could see what appears to be outflow pushing south and the band redeveloped/back built as it did so. Really neat, really.

  5. Geebus … thank goodness we don’t face things like this:

  6. W7ENK says:

    Well, I’m tired… Long day of anticipation with no payoff; today reminded me of one of those days where I’d spend all day waiting for snow, and it never comes, or worse, it snows EVERYWHERE but my neighborhood – that seemed to happen a lot growing up. I was almost convinced there was a glass bubble over Milwaukie that diverted snow and thunderstorms… today followed suit!

    Anyway, TV Met mentioned Steve Pierce on the 6pm show. Thought that was pretty cool.

    Here, have some numbers: 😛

    76.8°F High this afternoon
    53.8°F Low this morning, but it’s 54.0°F right now…
    I’ll just pretend it stays there until after midnight. 😕
    Wind SSW 21.4 mph at 5:44p
    0.08″ of rain, starting at ~5pm.

    Good night all.

  7. Battle Ground Brian says:

    Clark County Rainfall Report from 5:00pm to 10:30pm PDT

    Ranging from 1.15″ in Orchards/LaCamas Lake areas to less than a tenth in Battle Ground and Washougal areas tonight.

  8. W7ENK says:

    Realistically, what are the chances for storms again tomorrow? If the sun comes out, the atmosphere at the surface should warm nicely since that cold airmass off the coast has yet to push into our area, right? With all the rain put on the ground today and tonight, that should boost humidity up even further, I’d think.

    Maybe???

    looks like 00z is hinting at some potentially strong winds Wednesday night?

  10. 0.50″ rain from 8 to 8:30pm tonight (3.78″ rain rate)…1.10″ total…so far…amazing rain rates!

    • Battle Ground Brian says:

      That is truly amazing Mike,

      0.05″ tonight so far at Battle Ground Lake at of 930pm.

    • dabears (Hillsboro-Tanasbourne) says:

      To be totally honest, I don’t think that’s right. The radar showed no more than 40dbz in your area at that time. You sure that .50″ didn’t come over a little longer of a period?

    • dbz echo intensities are not the “only” thing that determines rainfall rates/totals..There are other factors as well….

      This is a new VPro 2 station that is correctly sited..I myself was amazed too..Neighboring CWOP/WU stations showed similar rates…Lots of streets were flooded in east Vancouver tonight…I think PDX had 3/4 inch of rain in an hour earlier tonight…

    • Rob "Wrath" S.E. Portland says:

      Yes

    • Noticed my CoCoRaHS gauge has well over an inch of rain in it!

  11. Snow-Zone/Monmouth-Elv200' says:

    Sure feels good outside. Really fresh and cool, 54.5F

  12. Tyler in Hazel Dell says:

    A quick change in the weather capture on my timelapse…

  13. Kyle says:

    Whoppe sever thunderstorm with straight line winds up to 60mph and frequent cloud to ground lightning to the west and north of me just outside of Silverton………………….NOT!

    I sure wish that was happening:

  14. AdamInAumsville says:

    OK everyone get your thinking caps on. Can anyone tell me about some intense thunderstorms to hit the valley during summer (July?) on back to back nights around 1993-1995 time frame? I known this is isn’t a lot of information to go on, but I remember these intense storms as a kid in Eugene. They were very violent with frequent lightning. There was actually a photo of the lightning over downtown Eugene (taken from Skinner’s Butte) in my dentist’s office for years.

    • Tyler in Hazel Dell says:

      I cant remember any details, but this is likely what got me interested in the weather! I remember staying out ALL NIGHT and watching lightning…still remember leaning against my dad’s work truck watching the immense display.

    • Rob "Wrath" S.E. Portland says:

      I can’t remember

  15. Ryan (Walnut Grove) says:

    Well a quick lightning strike, some thunder, and heavy rain. Can’t complain but I was hoping for more!

  16. Max in Fairview says:

    Cell developed over here. Pouring rain now.

    • Aleta-West Gresham says:

      Guess it just missed me. It rained lightly here but nothing impressive.

    • Rob "Wrath" S.E. Portland says:

      Same here, Aleta…. Yeah you could see activity back building to the south just into the Fairview area, but doesn’t look to move any farther south.

  17. W7ENK says:

    Still dry at the top of the hill in OC. Missed them completely!

  18. Only a couple light showers today, 0.08″ of rain. Never heard any thunder.

  19. Justin (Brush Prairie) says:

    PDX with 0.76″ of rain in the last hour. Almost a record.

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

    I personally will enjoy a much cooler house tonight. Maybe we see some cold core convection later this week?

    Now onto tonight’s 00z WRF-GFS to see what it does with that low pressure center Wednesday.

  21. Crazy dumping rain leaving PSU about half an hour ago. Felt nice after the relatively humid afternoon. Many people left unprepared without coats, etc – but not this weather nerd. 🙂

    I do, of course, wish it had been accompanied by our elusive friends, thunder and lightning.

  22. Aloha Rainshadow says:

    Late report from me in Aloha, chased the Beaverton cell as it exploded, saw about 3 bolts and heard some thunder. Nothing to special, thought I would see more, if we’d just had 10 more degrees today, that could have been something special for everyone!

  23. Tom (NE Portland) says:

    No lightning, no thunder….but freaking heavy rain! Kinda feels refreshing lol

  24. W7ENK says:

    I wasn’t all that impressed… 😦

    Just light to moderate rain, a little bit of wind, and now it’s too cold for shorts.

    I heard one rumble, in the distance.

  25. Tyler in Hazel Dell says:

    Yay lightning…that was about 10 minutes ago. Now just rain!
