Overnight Thunderstorms

That worked out well, quite a light show from 11:45pm-1am or so across a good chunk of the metro area and up into S.W. Washington.  Here’s a map of the cloud to ground strikes.  Keep in mind this doesn’t include cloud to cloud or in cloud strikes, so there was even more flashing than this:

    NATIONAL WEATHER SERVICE PORTLAND OR
    200 PM PDT WED SEP 4 2013

    WATER VAPOR IMAGERY SHOWS AN UPPER SHORTWAVE/JET ROUNDING THE BASE OF THE LOW
    HEADING TOWARDS THE PORTLAND FORECAST AREA. THIS FEATURE WILL STRENGTHEN AS THE LOW NEARS AND PROVIDE LIFT. INSTABILITY WILL ALSO INCREASE AS COOLER AIR ALOFT MOVES IN AND MID LEVEL LAPSE RATES
    INCREASE. MEANWHILE THE FLOW WILL TURN SOUTH TO SOUTHEASTERLY. THESE VARIABLES ALL SUPPORT THE POSSIBILITY FOR NOCTURNAL THUNDERSTORMS
    TONIGHT THROUGH THURSDAY MORNING.
    ONSHORE FLOW WILL RETURN THURSDAY AFTERNOON AS THE UPPER LOW CONTINUES TO PUSH INLAND. THIS WILL DIMINISH ELEVATED INSTABILITY THURSDAY…BUT COOLING TEMPERATURES ALOFT WILL KEEP A CONTINUED
    THREAT OF ISOLATED THUNDERSTORM ACTIVITY WITH LOCALLY HEAVY SHOWERS THROUGH THURSDAY EVENING.

    Whoa, Mark! Your 72 Hour RPM rainfall accumulation map…

    OK, let’s have some more fun!

    BRIEF HEAVY DOWNPOURS AND
    FREQUENT LIGHTNING ARE THE MAIN HAZARDS.

    NAM mm5 has over 5 inch 24h precip totals in WA Cascades as of Fri. It has even S valley getting some decent precip but best action farther N.

      Really glad I don’t need to worry about idiots throwing cigarettes outta their vehicle windows. You couldn’t start a fire at my residence without a lotta gas/oil.

    • W7ENK says:

      😆

      Where do you find this stuff?! Hahaha!!

      Have you seen the new ‘Smokey the Bear’ ads? Smokey isn’t as cheerful and friendly looking as he used to be, now instead of looking huggable he looks more like he’s about to kick some @$$. His slogan needs to chenge from “Only YOU can prevent wildfires.” to “If you don’t prevent wildfires, I’ll eat your face!” 😮

    • W7ENK says:

      *change

      FFS + Autocorrect FAIL. 😳

    • Yeah, I remember singing along with him…
      “Smokey the bear, Smokey the bear
      Huffin” and a puffin and a sniffin the air…” 🙂

    • pappoose in scappoose says:

      Funny stuff, W7! How about this!

    • W7ENK says:

      😆

      Just don’t let Smokey hear you do it…

  11. Jake-(Gresham) says:

    I’m not going to lie I hope we get another round of lightening tonight. Last night was pretty exciting!

  12. Impressive CAPE for Thursday afternoon for WA

  13. archangelmichael2 says:

    I sure hope Portland got their quota for lightning filled up this summer.

  14. BoringOregon says:

    Wow, 3:19 pm et 118mils West-southwest of Bella bella, Canada there was just now a 6.0 Earthquake !!

  15. Joe in Battle Ground says:

    I heard a loud “whip” that woke me up and the loudest Thunder I’ve ever heard… Must of been a close ground strike!!!

  16. High Desert Mat says:

    About time PDX got in on some of that action. Was tired of hogging it all east of the Cascades lol. Thinking you guys will have another round tomorrow night and into Thursday morning. Not sure how ill do in Redmond but I’m not worried about it. Sure it will happen tomorrow and Thursday for me. Just hope its not a repeat of two Sundays ago. That was bad.

  17. Hal in Aims says:

    nothing close enough here to get roused out of a sound sleep….missed the whole thing….

  18. pappoose in scappoose says:

    Can you imagine if all the lightning was cloud to ground strikes. Yikes!

  19. Lurkyloo says:

    I missed all of it 😦 That’ll teach me to go to bed at 10:30 …

  20. Garron near Washinton Square says:

    That was really frequent lightning with those cells as they passed over Beaverton last night. Made it almost impossible to count between the flashes and the rumbles. Really bright, and lasted about 2 hours. Ok, summer’s complete in my book. I’d love to have these warm nights and days continue until October ~ 15th, and I won’t even complain once about the 5 months that follow!

  21. Lightning started here around 11:30 PM and continued more or less non stop (a strike every 1-2 minutes at the slowest, to a peak of a strike every 5-10 seconds) until 2:30 AM.

    It seemed like a higher ration of the strikes were CC vs. CG, however, there were some close CG strikes as well.

    0.45″ for me from the storms.

    • pappoose in scappoose says:

      Frequency/duration of the lightning was certainly impressive.

      Suppose it’s a good thing to keep the lightning up in the clouds.
      No need to blast people/objects on the ground!

    Told you I’d bring some thunder up from Panama for you guys!

  23. W7ENK says:

    Repost from previous:

    Quite the show last night! Almost 3 hours of varying degrees of flashing and booming, and only 0.10″ of rain which was just enough to make the outdoors smell nice! Woke me up at around 12:20am, had a couple strikes that sounded fairly close to the house. Lots of CC, only a handful of CG, maybe a 10:1 ratio? Thankfully nothing too near my antenna tower — taking a hit to that would be a tad over the top!

    Repeat performance on Wednesday night? I should stock up on sleep tonight then. Getting up and riding in to work was rough this morning. Gotta make my goal of 80% for the month!

    62 degrees and fog along the Springwater Corridor was a little bizzare, though.

    • W7ENK says:

      That’s an interesting round dome-shaped hole in the CG strikes, directly over the core of PDX metro…

      Ya, lets do it again!

      BY WEDNESDAY NIGHT THE UPPER LOW BEGINS TO MOVE ONSHORE. EXPECT AN INCREASE IN CLOUDS WEDNESDAY EVENING… SO EXPECT INCREASING CLOUDS AND SHOWERS. MARGINAL INSTABILITY DEVELOPS IN THE SOUTHERLY FLOW ALOFT WED NIGHT…HELPED ALONG BY A 90KT JET. A DECENT SHORTWAVE MOVES THROUGH OVERNIGHT INTO EARLY THURSDAY AND BRINGS THE POTENTIAL FOR ELEVATED NOCTURNAL THUNDERSTORMS WED NIGHT. THE CENTER OF THE LOW MAKES LANDFALL NEAR THE CENTRAL OREGON COAST ON THURSDAY. THERE
      IS SOME INSTABILITY PRESENT AS THE UPPER LOW MOVES INLAND. THE BEST DYNAMICS GO TO THE SOUTH…BUT STILL LOOKS LIKE A HEAVY SHOWER
      ISOLATED THUNDER PATTERN WITH PLENTY OF CLOUD COVER IN PLACE. PRECIPITABLE WATER VALUES REMAIN ON THE HIGHER SIDE…AND SLOW STORM MOTION SUGGEST MODERATE TO HEAVY DOWNPOURS AND LOCALIZED PONDING OF WATER ON ROADWAYS…ESPECIALLY ALONG AND NORTH OF THE LOW IN THE DEFORMATION ZONE …WHICH WOULD HIGHLIGHT AREAS NORTH OF SALEM FOR NOW. /KMD

    • W7ENK says:

      Elevated nocturnal thunderstorms, eh?? I hope the marine layer stays away, or it might inhibit our view of much of the lightning.

    • I think in all fair judgment, we can look back at Summer 2013 in the end and say it was a good year for thunderstorm action. We got several different events during the southerly flow events these past 3 weeks or so. And some severe T-storm events both sides of the Cascades as well. I don’t think we’ve had a more active season for a few years at least….

      …the price of all this excitement, of course, being the high dewpoints and difficult sleep nights.

    • archangelmichael2 says:

      Let’s Limbo some more! Let’s Limbo some more. We’ll hit the floor like we did before. Let’s Limbo some more!

      Last nights downpour was pretty loud despite there being no lightning yet I only got less then 0.10 in my rain gauge?

  24. BoringOregon says:

    Well, another storm bust for me. one went to the north east of me and the other went to the west of me, ahhh i give up….

  25. Almost all the lightning I saw last night over Gresham was cloud-to-cloud. Beautiful evening.

    Does PDX get credit for 2 tstm days since it happened before midnight?
