A Wild Night Down South

lightning2Quite a surprise across a good chunk of Western Oregon this morning.  Widespread thunderstorms erupted with a cold front as it’s been moving inland.  Anyone driving I-5 from Salem to Grant’s Pass probably had a heck of a light show beginning around 2am or so.  I even see one strike (equipment only detects cloud to ground strikes) here in the Metro area this morning, near Lake Oswego/West Linn.

Okay, off to volunteering at my kid’s school this morning.  It’s early for 4th grade math, but I’ll try to re-learn something again this week.

10:30pm Update:

Quite a bit of trauma and drama going on in the weather center today…changes ahead!  I’ll elaborate more on some shifting schedules in a few days.  But this means I ran out of time to add any other thoughts.  I’ll post tomorrow.

    Chilly day up here only 44 deg.

  2. Ryan (Walnut Grove) says:

    Looks like there is going to be a pretty abrupt cut off following this initial wave of energy.

    Just about in time for me to head out to lunch at that. 🙂

  3. Looks like the changeover to snow may be beginning at Guv Camp (tripcheck.com cam – seems like it may be flakeage now falling, temp down to 33)

  4. Currently 48°F and light rain. . . .

    Looks like McMinnville is about to get hammered pretty quick here. . . .

  5. PrivatePilotWA says:

    Temp is dropping. Cold raw day today – was 58 at 8am this morning now 47. Here comes the snow for the mountains.

  6. muxpux says:

    that visible satellite this AM is beautiful. such defined boundaries…awesome!

  7. Line of heavy precipitation brought me 0.29″ rain in a half-hour (8:30-9am)….

    52.7F…raining…0.52″ so far

  8. Ah, it’s that time of the year again — when you rake up all of your leaves on Saturday, and Monday morning there are just as many, if not more, back on the ground…

  9. Timmy_Supercell (Hillsboro) says:

    This is one wierd shower! I have never seen an organized line like this in the middle of a cluster of showers…

    • Tyler says:

      I have…during several of our cold front passages 🙂

      I could tell the front had past just by looking at the window. It faces north, and if it’s west, I know we have a northerly component to the wind.

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

    Barometer continues to fall now at 29.77 in.

    • Rob "Wrath" S.E. Portland says:

      Barometer rising rapidly now up to 29.83 in. That line moved through here and wow gusts 30+ and sheets of rain. Wind has switched to NW now and temp has fallen quickly to 54.8F. It was 59.9F before the rain began.

  11. Ryan (Walnut Grove) says:

    Now that is a new one… According to Weatherunderground Vancouver is currently experiencing “Heavy Rain Mist.”

    • Sarah (E Gresham) says:

      I’ve seen that one before….it always amuses me.

    • Brenda, E Vancouver says:

      We just had a heavy down pour. I had to clear the drain on the street it was so bad. I still don’t understand why the city put a layer of felt over that drain. All it ever does now is clog up, it never did before. Oh well, it was fun to “play” in the down pour.

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

    Radar sure is neat looking with a sharp line of orange/red moving through SW Washington and into PDX metro.

    Zoomed radar

    • Punxsutawney (aka HIO Phil at work by Sunset High) says:

      Coming down in Buckets here in Beaverton!

    • stevied (North Portland) says:

      Yeah, I was noticing that, Rob. Nice 45-50dbz line.

    • Rob "Wrath" S.E. Portland says:

      GR2 showed 59db. Base Velocities 50+kts near Battle Ground and Brush Prairie. I wonder if SW Washington received any strong winds with that line.

    • Timmy_Supercell (Hillsboro) says:

      Man its POURING right now! Are getting it yet?

  13. Punxsutawney (aka HIO Phil at work by Sunset High) says:

    06z GFS,

    Says: Wet – then Chilly and wet, dry wed afternoon – thursday afternoon – and then wet, wet, wet!

    It calls for 18.67″ of rain over the next 16 days for PDX. I don’t expect that to verify, but fun to look at none the less.

  14. Tom (NE Portland) says:

    Wow quite a blustery morning out there. Kind of a surprise! Looks like the radar is filling in nicely, too…some moderate rain about to move into the metro area soon. Ahh, the joys of Fall!

  15. Eternal Yamcha (SE Milwaukie) says:

    Wind’s definitely dying off at Astoria, though it’s picking up at Newport (nothing impressive) and picking up across the valley.

    I see Portland’s picked up a peak gust of 32 which, while not really powerful, definitely caught me off guard.

    Troutdale had a 9 degree jump in under an hour as the winds shifted from E to SSW and picked up in speed.

    I’m looking at the WV and IR satellites and while I might be wishing and sleep deprived, I’m noticing what looks like a slight spin at 47 N and 127 W. I doubt anything’s gonna come of it, but it’s fun to look at.

    • Rob "Wrath" S.E. Portland says:

      That might be the wave I posted about earlier. I’m going to take another look at WV/IR.

    • Rob "Wrath" S.E. Portland says:

      I see the spin also. I also see on WV loop a lot of enhancement with cooling cloud tops on IR indicating strengthening front.

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

    Surface gradients
    As of 7 AM
    PDX-EUG: -5.4mb
    OLM-EUG: -6.5mb
    Looks like PDX-EUG is about to peak. I’m surprised it has exceeded 5mb.

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

    Barometer has fallen off a bit now 29.85 in.

    Surface gradients
    As of 6 AM
    PDX-EUG: -4.0mb
    OLM-EUG: -7.2mb

    • Rob "Wrath" S.E. Portland says:

      Breezy S-SW winds continue here ahead of the warm front. Winds are switching along the north Coast though as the warm front and rains begin…. Rainy day ahead.

    • Rob "Wrath" S.E. Portland says:

      Warm front passes*

  18. Timmy_Supercell (Hillsboro) says:

    Well, are thunderstorms like something we can just “expect” with every cold front now? 🙂

    This is just too much for words. I do NOT remember a fall like this.

  19. 54.9° and calm here.
