Last Storm Update

Okay, this is REALLY the last update. I’m home now and it looks like cold front has moved through; the wind is dying down quickly.

I think peak gusts were all 38-48 mph in the area (most around 40 mph) except for a lonesome gust in the 50s somewhere in Clark County. Not exactly a windstorm, but a nice warmup for something later this winter???

    See ya later folks, im dissappearing for the night.

    The problem for us wind storm lovers is the anchor/parent low that sets up in the Gulf of Alaska is a bit too far north and thus the trough not deep enough so that when waves develop near the trough axis around say 42-45 N they swing too far to our northwest. We need the parent lows to remain around 51-53 N. Until models show that I don’t realistically see how we can get a wide spread wind storm with a more classic S-N trajectory with wave development below 40 N. I do think we could get a shot at a December 2006 type wind event/storm under this pattern if we can manage a low inside 130 W, below 975mb and into central Vancouver Island.

    How often do you see Troutdale with the strongest gust recorded in the metro area during a south wind situation… Not very.

    • Timmy_Supercell (Hillsboro) says:

      Yes very unusual, id say many many years since that last happened.

    • Mark Nelsen says:

      Yeah, but they were all within 5-10 mph of each other. Even PDX and TTD were only 1 mph different.

    • Rob "Wrath" S.E. Portland says:

      Yep fairly uniform. I however only had a gust of 37.9mph. Usually I’m slightly above PDX. Unsure what to contribute that to. I would suggest the Gorge influence, but the southerlies had broke through long before the peak winds arrived. It’s just the fact winds don’t mix/surface in all locations at all times.

    Oh wow the SPC knocked out their t-storm forecast for us when they start developing…

  5. Mark Nelsen says:

    Whew! That storm summary of peak winds sent out by the NWS earlier today had a few wrong numbers, including PDX, UAO, and VUO. Not sure how that happened but I went back and looked at the ASOS PKWND observations to get the correct numbers. So I’ve updated that map above (the metro one) twice. That way I’ve got it for later in the winter or spring for my kids and grandchildren right?

    Thunderstorm now east of Cannon Beach intensifying…

    Peak reflectivity of 57 dBZ ๐Ÿ™‚

  7. You would think with all the waves forecasted in the models that one, just one, could become the “bomb” we need for a widespread windstorm….

      OMG WRF-GFS just went nuts! Does it seriously think we are even capable of having that many in a row? ๐Ÿ˜‰

  8. Clatsop County, look out…Fun in store for you

  9. Timmy_Supercell (Hillsboro) says:

    Seems to be some new development behind the Cannon Beach storm…. Interesting.

  10. Timmy_Supercell (Hillsboro) says:

    There is a rather good looking cell developing off Cannon Beach right now…

    Level 3 data indicates 0.50″ hail, 40% chance of severe hail.

    Enough of the t-storms and windstorms (or lack thereof)! Onto cold and snow please!

  12. cliff from sandy says:

    one last note, it’s 40 degs and calm in sandy.

    by the way, how does one input a diagram like the one mark nelsen did into this forum?

    could you please leave steps 1 – 4 on how to do it?

    thanks
