Quick Late Evening Post

Cold air mass definitely not as cold as models were showing in the past 24-48 hours.  So I raised 7 Day forecast numbers again…to 35/37/38 degree highs the next 3 days.  That might be too low.  I could see a 37 degree high at PDX tomorrow.

Wind isn’t too wild this evening, as models showed.  They have nailed that part of the forecast well.  I see PDX just peaked at 41 mph but just about all other locations are much weaker.  I expect most gusts will stay below 35 mph.  PLOT_Wind_Metro  Interesting to note that PDX is stronger than Corbett AND Vista House at this hour!  That’s very rare.  I’ve been watching the snow blow around on our Skibowl Camera this evening…Brrr!  Check out the  temps:  PLOT_Temps_MtHood_CamOnly

Because of the cold temps and wind, the NWS has a Wind Chill Warning out for the higher parts of the Cascades, this includes Tuesday so be careful and cover all your exposed skin if you’re headed up around 5,000′ or so on the open slopes.

Other than the cold and breezy wind, some great sunshine now looking likely through Friday.  Beyond that ridging seems to stick around off/on through the middle of next week.

    Eugene as of 9am obs is 1mb under Dec record, 2mb under all time high pressure record

    I believe Boeing Field in Seattle just set a pressure record. Currently 30.84″ there, old record was 30.83″ back in the 1920s some time.

    • David B. says:

      Yup, new record for Seattle.

      Doesn’t look like Portland is going to set a pressure record with this one. Your record is 30.84″ set back in 1880, looks like PDX maxed out at 30.79″ with this event a few hours ago (now falling).

      According to Portland NWS, it’s a record for December. Previous December record for Portland was 30.74″ on 12/1/2011.

      Astoria set an all-time record high pressure this morning of 30.74″

    • David B. says:

      Consider it a consolation prize from the weather gods for the disappointingly high temperatures.

    • W7ENK says:

      I’d probably enjoy it much more if my head didn’t feel like it was in a vice, my eyes stopped throbbing and watering, my ears stopped “hissing” and the shoulder TriMet wrenched for me last summer didn’t feel like it just got kicked in the bawls… Other than that, this is great!

    • Boydo3 N. Albany elev. just under 500' says:

      Was wondering what was causing the pressure in my head!

    • paulbeugene says:

      Interesting to note that all time low pressure for PDX was within a month of all time high pressure. That would have been a good month for this blog. My how things have changed since 1880

    • Garron near Washington square says:

      So we trade arctic event(s) and possible snow storm(s) to nose bleeds and headaches, seems a fair trade!

    • David B. says:

      Unless you’re easily sickened by, say, spending a few days in the mountains or the high desert of eastern Oregon then returning to Portland (which exposes one to a much more sudden and dramatic increase in pressure than this high-pressure system has), I’m afraid I have to chalk up most of the complaints about the pressure on health to be either psychosomatic or misattributed (i.e. a minor sinus infection that would have caused misery no matter what the air pressure).

  3. MasterNate says:

    Low so far 28. Still windy with a max 32 mph from the east. Pressure 30.73

  4. This is where you insert the sad trombone… Winter seems to be on life support at this point.

    The clear skies and sun is nice though.

    Ok, time to move on……nothing here…….bring on summer!!!

  6. W7ENK says:

    My overnight temperature bottomed out at 28 with virtually no wind whatsoever. I’ve had colder nights without any “arctic air mass” in place. I believe that’s grounds to officially call this forecast a bust.

    • David B. says:

      It made it up to 41 up this way even with outflow winds blowing. That’s just a few degrees below average. Any day with highs in the forties can’t qualify as “arctic” in my book. A month ago, it promptly dropped into the 20s when the outflow winds hit and stayed there through the daylight hours.

      This event is noteworthy because of the barometric pressure readings but certainly not the temperature readings.

  7. Tyler Mode in Battle Ground says:

    28 here this morning. Peak wind of 23 mph. Pressure an astonishing 30.77″ and still rising.

    I did reach 30.78″ on December 1st, 2011 though…we’ll see if I can break that today…

    • Tyler Mode in Battle Ground says:

      And just as I type that the wind goes completely calm. Quickly down to 25 degrees.

  8. My damn thermometer does terrible below freezing… luckily i have 3.

    I love watching my “winter cams” at night….the snow can be mesmerizing!
