2pm Wednesday; Inversion Lowering a Bit

We found sunshine over Portland!  Unfortunately you have to travel up to around 1500′ to find it.  This is the 2pm view from our tower cam at 1,800′. I was happy to see the sun up there at least.  We’re timelapsing it right now and I’ll try to post the movie later.  It’s always fun to see the movement in the low cloud layer; like watching someone stir a thick soup?

Temperatures in some Cascade locations have reached into the 60s today!  Meanwhile, stuck below the inversion in the fog and low clouds we are having real trouble reaching towards 40.

There are hints we might see some clearing in spots the next 24 hours…the WRF-GFS pushes east wind out of the Gorge and into the east part of the metro area tomorrow.  Interesting, I’ll blog again later.

    Currently 31.1
    Fog level was at my level now has risen a couple hundred above me.

  2. Hope Mark gets to see the link I posted earlier. Very pertinent to feelings here on the blog once in awhile :)

    Told you so.

    Hi all! Long time lurker here with a question for the weather guru’s. With this inversion layer messing up my weather-fu I can’t figure out what kind of low overnight temps I can expect at the 4,000 foot level. I want to go snow camping south of Oakridge and am not sure if it’s going to be 30 or 3? Anyone have some insight?

    • Lurkyloo says:

      Hi fellow lurker! I have no idea about temps and such, but I’m impressed (and kinda jealous) that you’ll be snow camping. That sounds fun! I’d say be prepared for anything and everything.

    Where did Crown Point go? Offline since 6:16.

  6. Don’t even look at the GFS 0z run. You’ll just get excited and then let down on the next run. Besides 9 days out is just a tease. Don’t look. Please.

    Chip Kelly won’t mind leaving the Eugene fogversion….one is panning out to be a real bummer of a big ridge, could have been an element in tipping him over to leaving town. Going up Spencer Butte again tomorrow to get a glimpse of sun, 50 degree plus temps and dewpoint below zero

    • paulbeugene says:

      Since this weather pattern started the highs and lows at my station have been:
      1/16 34/32
      1/15 35/24
      1/14 39/25
      1/13 31/27
      1/12 36/25
      1/11 42/28

    I had a great hike today! Temps ranged from 29 degrees up to 54…all bundled up at the bottom, and t-shirts and shorts at the top!

    Mark will be using my pics again on the 10 PM weather cast if anyone is interested. I also took temps as I hiked today, the inversion was approximately 1,700-1,800′ deep.

    At 1,700′ the temp was 29 with fog and heavy rime ice. By 1,900′, the temp was up in the upper 30s to low 40s and there was no ice at all (except melting snow).

    At the summit, 2,400′, the temp was a balmy 54 with hardly any wind.

  10. East wind has developed….. YES! This means I might get out of the muck overnight and be sunny tomorrow.

    • Punxsutawney aka HIOPHIL in Hillsboro says:

      Even East wind here right now. Yes, the air is actually moving! A gust to all of 6mph in the last half hour if I dare say it! Doesn’t sound like much, but that’s the highest wind speed I’ve had since the 11th with a peak of a whopping 8mph.

    • Hey! I just had a gust of 1mph!!! The soup is simmering!

  11. This has to be one of the strongest inversions I can ever remember!
    Upper Sensor 48.7
    Middle Sensor 29.8
    Lower Sensor 30.7
    A 19 degree difference in just 445 feet! Crazy folks. Insanely crazy craziness.

  12. Just could NOT resist….hope this works & hope it is ok :) Wonder if this is how W7 & his neighbors would react?? j/k

    Wonderful YouTube video from Dec. 2008 (the last real decent snowfall we had in PDX): http://www.youtube.com/watch?v=_NQE26y3yjE

    • ocpaul says:

      What a great video! I love the snow weight on the cedars and Doug Firs. Just proves, every city looks better by a power of 10 with snow. And the more the better.

  14. Wendy-Silverlake, Wa says:

    Made it to 34 today. The trees are completely white. I’m not sure if it’s leftover snow or if it’s freezing fog in the trees.

  15. Beautiful sunny day here in western NY! Temp was about 35dg so pretty nice fr around here. They’re saying highs of only 15 or so and lows near 0 into next week… a nice taste of true winter!

  16. wwm says:

    beautiful day up here and cold, pretty funny to drive a mere 100 feet or so down the road and get back into fog/low clouds. I thought for sure we would be close to 40 today with all the talk of a warm-up and the sun, ended up getting to 33* but it is already cooling off quick and back down to 31*

  17. thomyee says:

    NWS/CPC are at least giving us hope that winter isn’t over yet, calling for a retrogression of the ridge and below normal temps day 8-14:

    8-14 DAY OUTLOOK FOR JAN 24 – 30 2013

    THE 6Z GFS AND 0Z ECMWF ENSEMBLE MEANS ALONG WITH THE HIGH-RESOLUTION 6Z GFS
    MODEL INDICATE A RETROGRESSION OF THE WESTERN CONUS RIDGE TO THE NORTHEAST
    PACIFIC. THE WESTWARD SHIFT OF THE UPPER-LEVEL RIDGE IS EXPECTED TO RESULT IN
    LOWER 500-HPA HEIGHTS ACROSS THE WESTERN CONUS. AN UPPER-LEVEL TROUGH IS
    EXPECTED TO PERSIST ACROSS THE HIGH LATITUDES OF EASTERN NORTH AMERICA WITH AN
    INCREASE IN 500-HPA HEIGHTS ACROSS THE SOUTHEASTERN CONUS. VERY LARGE SPREAD
    AMONG THE 0Z GFS ENSEMBLE MEMBERS RESULTS IN NEAR AVERAGE 500-HPA HEIGHTS
    FORECAST BY THE 0Z GFS ENSEMBLE MEAN ACROSS THE PACIFIC AND NORTH AMERICA.
    THEREFORE, THE 0Z GFS ENSEMBLE MEAN WAS NOT USED IN CREATING THE 500-HPA BLEND

    • Marcus says:

      We shall see sounds like a sliver of hope.

    • Ben T says:

      8-14 days? I thought Rob said as soon as 7 days possibly?

    • thomyee says:

      Rob is the man, so I am sure he will give us his thoughts when he is ready. I think he was saying the pattern appears to be making a change around day 7, which is the “start” of a change. We then see what pattern we end up with after 7 days, and the new pattern would start showing in 8-14 days +/-.

    • PDX Weather Nut says:

      Winter over? Come on, we had a mild November and December and are just halfway into January.

  18. germantownsummit1000' says:

    Visibility, right now, on NW Skyline between Germantown & Cornell is 50′ – SCARY in “daylight”, I WOULD NOT drive it at night. This despite living up here for 27 years. I’ve never seen it this thick outside of a soup bowl.

  19. steveofportland says:

    Curious – where those towers are located?

  20. runrain says:

    Classic inversion graph for the tower temps. Check it out!

  21. runrain says:

    What could be worse than fog? How about two Mondays as a showing on the seven-day. Well, Groundhog Day is just around the corner. All we need now is Bill Murray.

  22. I’m not sure what’s better, Sunday when my low was 27 and the high was 29 or today when my low was 32 and the high is 34. I guess Sunday since we had frosty trees. This just sucks cold eggs.

  23. W7ENK says:

    It’s about time… Now, can we get it to lower all the way below ground so we can get some sunshine down in here? Sheesh!

  24. pappoose in scappoose says:

    Who’s on first?

  25. Sifton says:

    58 degrees @ Yaquina Bay bridge?!?! This is B.S., I’m getting robbed here of some sunshine! Never thought I would root for a serious East wind…………
