9pm Sunday: Storms Moving Over Cascade Crest

Why, oh why, am I not camping at Olallie Lake TONIGHT instead of last week???  Look at the last hour’s worth of lightning strikes.  They sure aren’t strong storms, but they are producing dozens of strikes every 15 minutes.  It’ll soon be visible in the sky to the SE of the metro area as darkness moves in…

    I was up at Olallie Camping in a Hammock with a rain-fly on the 5th. It was intense. I really wish I had brought my camera out with me that night.

    Just got back from Monon Lake, next to Olallie. That storm was by far the most intense I’ve ever experienced. It only lasted about 30 mins, but it was incredible. The sky around Mt. Jeff looked like it was on fire. The ground was actually rumbling for several minutes straight, almost earthquake-like … definitely a first for me. The reverberation off of Olallie Butte through the meadows was unreal. No way of describing the uniqueness and intensity of that sound.

    The heliscouts were out first thing this morning. We ran into a park ranger on our way out who told us several small fires started between us and Timber Lake overnight, but all manageable with bucket drops. Fingers crossed. That area needs the break.

    Just was out side in saw that. It was a good light show what happen!?!?

  4. Past 20 minutes lightning activity has really dropped off.

  5. Ooooh these are gonna be close! If we’re lucky enough we have a front row seat right out the garage door

  6. Are the tower cams online??

    .SHORT TERM…CURRENT SATELLITE AND RADAR IMAGERY SHOW A BROAD CLOUD SHIELD AND ISOLATED THUNDERSTORMS OVERSPREADING NORTHWESTERN OREGON AND SOUTHWEST WASHINGTON. AN IMPRESSIVE CLOUD/VIRGA STORM IS UNDERWAY. IT SHOULD BE NOTED HOWEVER THAT RAIN IS REACHING THE GROUND ACROSS THE CASCADES AND EVEN INTO A FEW FOOTHILL LOCATIONS. GIVEN THE CURRENT STRENGTH OF THE REMAINING SHOWERS…THERE IS A CHANCE THAT A FEW OF THESE WILL BRING SPRINKLES AND/OR LIGHT RAIN TO PARTS OF THE WILLAMETTE VALLEY AROUND MIDNIGHT.

    THE CLOUDS OVERSPREADING THE REGION ARE THE BLOW OFF OF SEVERAL IMPRESSIVE SURFACE BASED THUNDERSTORMS THAT DEVELOPED BETWEEN WILLAMETTE PASS AND BEND THIS EVENING. SURFACE BASED THUNDERSTORMS HAVE BEEN UNABLE TO SUSTAIN THEMSELVES WEST OF THE CASCADE CREST DUE TO A SUBSTANTIAL CAP. THERE IS A CHANCE THAT A FEW OF THE REMAINING STORMS WILL TAP INTO THE MID LEVEL INSTABILITY PRESENT AND SUSTAIN THEMSELVES AS THEY TRAVERSE NORTHWESTWARDS LATE THIS EVENING. HOWEVER…GIVEN THE SUBSIDENCE LIKELY OCCURRING ON THE DOWNSTREAM SIDE OF THE CURRENT CLOUD ANVILS…THIS DOES NOT SEEM TOO LIKELY.

    AS A RESULT…I INCREASE POPS OVERNIGHT…BUT REMOVED THE THUNDER MENTION FROM THE WILLAMETTE VALLEY. /NEUMAN

    LOOK! The leader of the pack!

  9. Still a good bit of lightning activity on AM radio, and echoes are decent at best on radar, but I generally never like to see a broad uniform area of showers with a large, sprawling mass of clouds like this rather prefer more isolated cells. Storm tops aren’t that impressive 24-31k. I wonder what happens when these move into the warmer low level air mass over Clackamas and Marion County.

  10. Looked pretty likely earlier but now is fading away…..

    Look out! We’re about to be TRAMPLED!!

    Will these storms hold together for the metro area late tonight?

  13. I’m heading up to Olallie tomorrow morning around 3:30 AM. I guess it would be pretty cool to have ongoing storms when I head out. I’m not all that confident looking at radar trends. I just see an evolving mass of moderate showers with some lightning. Hopefully these hold together into Clackamas County. Mesoscale Analysis shows enough MUCAPE for that. OH and it is really muggy out. It’s still 84.7 here with solid clouds. Perhaps after this initial wave of energy moves north we see more development after 1-3 AM.

    It is visible now from our Skyline Camera in the West Hills
