Cold & Windy

That’s the story for the foreseeable future.  Looking back to November, we had the 9 day dry spell, then about 10 days of rain, now it’s back to a big blocking/splitting ridge of high pressure.  I think it’s quite likely that we won’t see rain through at least the end of NEXT week.

The big difference with this dry spell will be the temperatures.  Half the Columbia Basin east of the Cascades is snow-covered and that produces plenty of cold air that pools up eastside.  Of course the Gorge is the only near sea-level gap through the mountains, so where the air exits will be the coldest spot west of the Cascades the next few days  That would be the Portland Metro Area.  In this stable pattern, we won’t see highs in Portland rise above 44 degrees over the next 5+ days.

Sorry eastsiders!  This means a long spell of strong east wind that is about 10 degrees colder than the episode before Thanksgiving.  The good news is that Gorge waterfalls are beginning to ice up (barely got above freezing at Multnomah Falls today), and with sunshine the next few days…good picture-taking opportunities will abound.

The wind may die down slightly Thursday, then really ramp up Friday-Sunday.  I expect gusts to 70 mph again within the Gorge then.  Brrr!

    It appears that anything east of 205 in Vancouver managed to dodge the wind for the most part. I’ve been driving around town and noticed in most cases the wind was calm. It certainly feels colder then what the themometer has been telling me. It’s been around 41 all day here and it feels colder today then it did when we had threats of snow.

    Mark, I’d like to see Salem included in your metro-area current conditions. We are part of your local viewing area, too. Thanks and keep up the good work.

  3. Ahhhhhh the chill of winter in Corbett. Our (Corbett Schools)wind chill is bouncing between 9 and 10F this morning. …makes for cold trips between the buildings.
    We should see a good ice castle development along the Hist. Highway the next few days. I too, am anticipating an interesting event if a wet system pushes the High Pressure away next week……or when ever it happens. People might be interested in viewing the conditions in Corbett. Our weather station is located on the top of the Grade School Gym, right in the blow zone. To view the data, log onto the Corbett School District home page (www.corbett.k12.or.us), and go to the news & events dropdown menu, and click on weather station.

    I’m headed up to hike to Devil’s Rest tomorrow. Was going to go to Benson Plateau but at 4,000′, it will have a lot of snow and I don’t have snow shoes. I hope the waterfalls are freezing well because I would love to get some good pictures. I’ll try to get some to you if I can.

    Cold & Windy for a while, huh. Reminds me of the setup of the Winter Storm back in January 2004.

    Mark,
    Do you have any concerns about this blocking pattern lasting like the ones we had last year? It seems like we can’t get rid of the + PNA pattern, except for brief periods so far this fall. Thanks.

  7. Derek says:

    Hey Mark, if this pattern of cold east wind continues until our next storm system comes in do you think we might have a decent shot at some kind of worthwhile snow or ice event?

    Hello I got a few quick comments/question for you I don’t know how you can answer it but I’ll ask it anyway… I live at about 600 foot elivation right between Mt. Scott and Gresham I tend to get the east wind chill and the elivation factor if the weather gets cold enough. I have a fairly accurate thermometer and right now it reads 31 degrees and I went out back and my bucket of water was solid ice. I know it has been frozen all day, but does the east wind keep ice from unfreezing or freeze it quicker?

    Hello Mark!! It’s one of your old interns from the KOIN days. Hope the family is well.
    We moved out to Boise a year and a half ago. You’re correct in the intensity of the cold air over here: we’re already down to 15, with a predicted low in the single digits. Portland will be stuck in an east wind pattern for several days until something can sweep away this cold air(won’t happen for at least 10+ days according to most GFS runs)
    Congrats on the correct forecast last week. I was following that situation too, and couldn’t believe the NWS chose to keep the warning up in the mid evening, when the precip was less than 6 hours away, and winds were still from the NW. Not to mention that even when the winds did turn offshore, it remained in the upper 30s and low 40s.
    Would you agree that for Portland to be successful in receiving frozen precip, Pendleton must be in the 20s, and the east winds would need to be strong for at least a day?

  11. Paul in Beaverton/Tigard says:

    Mark with the next five days of constant east winds and the snow cover east of the cascades, is it inevitable that we are to face some sort of “event” during the transition back to a “normal” onshore flow of low level air?

    As a Portlander in Chicago just for the week, I can’t wait to get home. It was 5 degrees here this morning, and that’s not including the wind chill. How do people live in this?!?!?!? Can’t wait to get back to a higher humidity climate…
