Strong East Wind Today

The pressure gradient through the Columbia River Gorge jumped into the 10-11 millibar range this afternoon/evening, pushing strong east winds not only through the west end of the Gorge but also into the metro area.  Peak gusts reached 30-45 mph in many spots.  MarkEastWind_GorgeToAllMetro2 MarkEastWind_GorgeToAllMetro

And check out Vista House!  Peak gust to 90 mph several times up there this evening!  Capture Quite a long stretch of extreme wind.  Gradients should decrease just a little tomorrow, then be much weaker for lighter east wind Thursday & Friday.

The wind is keeping our temperatures a good 10 degrees warmer compared to last night’s calm conditions.  That’s good because we COULD see a sprinkle later tonight.  There’s a weak system moving north.  But models also show almost nothing make it into northern Oregon so I pretty much ignored it.

Bad news for skiers, due to the 11″ on the ground (and forecast rain), Mt. Hood Meadows has closed until a good snowpack develops.  That leaves only Mt. Bachelor operating daily with anything other than a bunny lift.  Yes, Timberline can open their Palmer snowfield on sunny days, but that’s about it.  The pattern remains very warm for the next 8 days as mentioned in last night’s posting. MarkSnow_MtHoodFcst_2013

    The high wind idea shown on models during the past couple days, for about Dec 11-13 has come and gone, with splitting of the jet toward Canada and California. Euro weeklies show a very splitty pattern over the next 2 weeks, with return of the ridge to G of AK by Christmas with arctic or fake arctic cold air invading the intermountain west USA/Interior PacNW. That of course is not shown much in the weekly ensemble mean, but timing might be right, if not convenient. Unfortunately, that would continue a very bad scenario for the ski industry with ongoing light precip/snowfall in the mountains.

  2. High Desert Mat says:

    I’m really liking how no cold air invades the entire US for at least the next week, seems to be bottled up in Siberia and northern Canada. Keep an eye on those temps as sooner or later it will invade. Just a question of when and where. ’49-’50 redux? Probably not but history does repeat itself.

    Freezing rain washougal temp at 31 east wind still ripping!

  4. W7ENK says:

    Still no El Niño, officially. 65% probability.

    FWIW, we’ve seen multiple snow events bust in recent years that were more certain than this.

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

      Actually they are saying we now have a 58% chance but looking at the weekly ENSO update, I’d say the ocean is in El Nino territory right now. But to be classified as officially “El Nino” it has to stay there for three consecutive three-month periods.

      Looking at the MEI chart here:
      http://www.esrl.noaa.gov/psd/enso/mei/

      It’s evident that 1990, which was a cold/snowy winter in the lowlands, was in weakly positive territory. So it’s certainly possible. A positive MEI hardly rules out significant lowland snow.

      And even if the winter as a whole ends up warmer than average, it’s still possible for there to be significant cold snaps. This autumn as a whole is still doubtless in warmer-than-average territory (remember how mild September and October were? and the record-warm episode just before the most recent arctic blast?).

      Plus, we have the correlation between snow in November and snow later on in the season working in our favor this year.

    Did the east wind die at Crown Point? Not likely! More likely the sensor is frozen 🙂

  6. To go along with what Paul said below, Models are starting to make some noise about a possible wind storm pattern. Beginning this weekend a very powerful jet 180-200mph moves off of Asia. Fast forward to Monday-Tuesday and this now stretches across nearly the entire north Pacific and importantly at a fairly low latitude just below 40 N showing good jet suppression. Both GFS and ECMWF show a very deep low spins up outside 130 W curving northward towards the Queen Charlotte Islands.

    This would be the parent low and main driver in this evolution as it sets up a favorable pattern for shortwaves/low pressure areas to rapidly develop around the bottom/base of the 500mb trough. I would target this possibility somewhere around December 10th-12th. 300mb model shows there will also be excellent left exit jet support of 140-160mph right up along the Oregon Coast into western Oregon. It is something to keep an eye on and don’t be surprised in the coming days if a model run or two shows a fairly significant wind storm impacting Oregon/Washington. 00z GFS Ensemble 500mb mean looks very favorable as well with the trough inside 132 W.

    Many model runs to go…..

  7. Its 34 in Boring now. I’m just praying my kids will still have school. It all depends on Sandy.

  8. 34.9, Dp 26.7, E wind still gusty…. It’s going to be much closer than I thought if I see possible ZR. The ground might be close to frozen thanks to all of the bitter strong east wind we’ve had.

    Interesting driving on the freeway this evening. Just got back from driving on I-205 and then going East on I-84. The humidity is so low that even though it’s raining pretty decent out there the roads are still staying dry in terms of having no standing water. I was able to drive full freeway speed no problem.

  10. moosieman says:

    FYI Jason (talking about the cold pool forming in the gulf of A) If i’m not mistaken, The first push in 1989-90 came directly from the Gulf of Alaska. It was a Northwesterly push initially then the omega block set into place.

  11. paulbeugene says:

    Am issuing a high wind watch watch watch for Dec 13.

    Which means that there is a possibility that there may be a possibility that there may be a possibility of high winds affecting Oregon and Washington on Dec 13.

    Very deep storm (950s mb or deeper) shown on models developing probably about 600-1000 miles W of the Pac NW, tracking toward the SW of Queen Charlottes, serving as parent low for a storm that tracks along to the S, curving up toward our region.

    Still 8 days away or so.

    Nice little ice storm going on here in Redmond. Rarity for here. 23 and sleet and zr falling now. About a 1/4″ so far. Looks to warm to about freezing for the morning commute then on to a warm day. Hopefully this pattern sets back up for Xmas.

  15. I think the terrorists are messing with the weather making ski resorts remain closed! 😂

  16. Jason Hougak says:

    Thurs 11th and Fri 12th look great for lower elevation snow with NW flow out of the gulf of Alaska fed from a large pool of cold air.

  17. Jason Hougak says:

    I like the blog because we can post and decide whether or not to read or answer. Rob loves weather… I get that. Other discussions are fun and funny. Some are good for blog debate…. even if it’s not totally weather related.

    My average precip for the 3 month period is down about 2″.

  19. Crown Point Wind Event November 30th – December 3rd

    This prolific and possibly historic east wind event began November 30th with the peak occurring December 2nd – 3rd. The following are gusts that exceeded 80-90mph+. In comparison to the November 10th – 19th event it was not as long in duration, but it was more impressive in magnitude and recorded more gusts of 90mph or greater. The peak thus far this year is November 17th at 92mph.

    • = Sustained winds of 60mph or greater and/or gusts of 90mph or greater

    “The coldest winter I ever spent was a summer in San Francisco.” ~Mark Twain~

    They’re getting a lot of rain down there this week.

  21. runrain says:

    Incredible sunrise this morning. I hope it didn’t knock Erik off his bike on the way to work.

  22. runrain says:

    Just hit 91 mph at Vista House.

  23. Jake-(Gresham) says:

    Well according to Wunderground tomorrow is the last day of 0% humidity it looks as if Thursday it should rise to around 80% in the Portland metro area.

  24. I assume that this strong wind is being caused by a “fake cold” layer in the Columbia Basin?

    • High Desert Mat says:

      Most likely “fake” cold but not fake enough yet as snow is falling now here in Redmond. Inversion yes, but not inversion enough to make zr just yet. Yes I know, its right around the corner then we go to a much warmer and drier pattern. Calm before the later Dec snowstorm.
