Back to Normal: Wintry Weather Returns

Our freakish late November “heat wave” has ended.  After spending 4 days above our NORMAL HIGH TEMPERATURE (49-50), we just dropped to 48 degrees as a cold front moved overhead and the wind switched around to gusty northwesterly instead of the constant/warm south wind.

Let’s recap the 5 warm temperature records tied or broken at PDX:

TUESDAY:  Tied record high temp (63), new record warm low temp (54)
WEDNESDAY: New record high temp (62), new record warm low temp (54)
THURSDAY: New record warm low temp (54)

This has totally decimated what little Cascade snowpack we had.  Both Timberline and Meadows went from about a 2 foot base to just patches of snow on the ground with lots of bare spots.  The official SNOTEL sensor at 5400′ just below Timberline went from 19″ to 4″ depth.  During that time 4.80″ of rain fell.

Good news though!  Looks like up to a foot could fall in the next 18 hours.  Here’s the plan:

If you are traveling the next 2 days, this means bad news in the mountains…

I’ll blog later (after evening models come in) about the possibility for lower elevation snow and/or freezing rain.

    27 degrees here with a dusting of snow on the ground. North wind is raging. Fraser outflow is definitely here.

    Streets mostly just wet with a few slushy spots. May well get worse over the next few hours as the icy wind freezes things.

    About as much snow as I expected to get, given the forecast. I don’t expect much more to fall here. What I got probably fell as the arctic front passed through, wringing out remaining moisture in the air from yesterday’s rain storm.

    • David B. says:

      Wow… outflow winds are really starting to rage. Think the NWS erred in not issuing a wind advisory for my area. There’s going to be power outages if this keeps up.

    Looking for an answer, are these ups and downs with the jet stream associated with rossby waves. Seems once the pattern starts there is not a lot that can breaks it. Kinda like last winters mega block. Trying to learn more, little help here. If the pattern continues then who knows how many warm cold periods we could have. It’s not even winter.

  5. OK, “Nipples are natures thermometer”.

    • Jason Hougak says:

      Nice new addition to your alias, location and elevation. I thinks your on to something.
      I’m having a bust moment for snow… I just don’t feel that excited. Now a winter storm warning and a guaranteed foot plus would do it!

      That station is in the heart of the Puget Sound Convergence Zone and at 500 feet elevation, so it’s not a big surprise. In fact, Paine Field was reporting snow briefly this afternoon.

      36 and rain on Bainbridge Island right now. Would not be surprised if there’s “splats” in it.

  8. GTS1K' says:

    39 flat now…

  9. Jason Hougak says:

    32.4F in Govy and snowing

  10. Pat -n- Garden Home says:

    Was 48 at five thirty and is 43 now…. Cold front passing through.

  11. Jason Hougak says:

    38F @ Govy and Blue Box Pass, cooling down quicker here.

  12. It appears the transition from rain to snow at the pass level has occurred.

  13. W7ENK says:

    It’s weird, I’m over in Yakima right now and it was dry, windy from the SW, with temps in the mid 60s. The wind has slacked a bit, but it’s still in the mid 50s right now. Seems the leading edge of the arctic boundary has already pushed through Portland at the moment, but it’s hung up over here in the Columbia Basin?

    Maybe it’s not weird… I dunno.

    • Arctic front is now into Lynden and north side of Bellingham as the expected northeast wind shift is occurring. Right on schedule. East winds will increase dramatically in/around Bellingham tonight, perhaps gusting over 50-55mph before this is over. Looking at the Columbia Basin it appears the arctic front is located somewhere between Omak and Ephrata heading south. Gradients: BLI-YWL -16.7, OMK-YKA -17.5

    • Lurkyloo says:

      Not weird for you, Erik. The Dome follows you.

    • Runtmc says:

      Old W7 is playing the jester here, implying that the various reports of cooling temps on the blog are premature, wishful, inaccurate. He’s feigning surprise because he’s a very funny man. He scoffs at the pathetic irrationality of us all.

    • dharmabum says:

      It’s of no consequence to me

    • GTS1K' says:

      RTMC,

      werd!

    • W7ENK says:

      Really guys? C’mon. I just spent the weekend helping my friend move his mother’s belongings out of her house BECAUSE SHE HAD A F’KING STROKE and probably won’t last through the end of the year!! So pardon me for not wasting my day away like you boys, sitting at the computer with my pants around my ankles, one hand on the mouse clicking refresh and the other wrapped tightly around my semi-hard c0ck whackin’ it to weather models, obs and the ill-guided words of a self proclaimed guru of moving air.

      Go do something better with your lives, @$$holes. Get off my $#!+

    • W7ENK says:

      Oh, and please Mark, go ahead and moderate me for breaking the rules. But don’t you dare block McRunt and Germantown&Skyline, considering nearly 100% of both their posts are simply slams, jabs and pokes at me. Hell, McRunt has never once posted weather info. Not once. But I guess that’s okay, I want both these douchenozzles to just keep running their mouths…

    • Marc (East Vancouver) says:

      Sensitive?

  14. Thanks for the update, Mark. Good to see you back. Hopefully you can clean somethings up around here.

  15. dharmabum says:

    I’m going to pick up my aquarium tomorrow, luckily that is down to the Salem area, if the going gets tough I bet I could call Jason.

  16. Hal in Aims says:

    went from 52 at 5:30 to 42 at 6:30……not fit fer man nor beast out………

  17. Jason Hougak says:

    Went out to get firewood and it was 50F and now it’s 44F! Wow… nothing like the 27 degree drop in 9 minutes in Montana but hey still impressive. Snowing at Timberline!

  18. GTS1K' says:

    Chilly on the way…

  19. The temperature drop was -1 degrees Fahrenheit per minute for 5 minutes!

  20. Pat -n- Garden Hm. says:

    Looking forward to wintery conditions….

  21. Damn I want to know now! Haha lol
