Snow Returns; First Time in 7 Weeks

9:30am Wednesday

Well that was interesting.  I forecast snow based on computer modeling alone yesterday afternoon/evening.

Lets imagine we didn’t have any numerical simulations of the atmosphere (THE MODELS).  Looking at observations last night in our area, I would not have forecast snow.  It wasn’t cold enough.  For example at midnight I’m driving through Portland on the way home and temps were in the low 40s!  No cold Gorge wind blowing and cloudy skies so no nighttime cooling.  Dewpoints weren’t that low so evaporational cooling shouldn’t have been able to produce overnight snow at the lowest elevations. But models kept insisting the column of air overhead would cool…2-3 hours later IT DID! #ComputersTakingOver


I had 2″ at 1,000′ east of Corbett. I know it was a trace accumulation or just in the air for the lowest elevations, but we expected that. If you got more than 1/2″ let me know in the comments below…we use the info for a snow map on-air.

  1. 0 inches 47 degrees in Castle Rock, Washington. and I think I jsut signed in with the wrong account? At any rate it saying Partly skies with in 24 to 48 hours. We had a high of 50. seriously considering getting a small weather station that can tie in with the internet. We have a few around us, but we live near the river and the weather seems to be slightly different in some areas.

    Cascades are getting and going to be hammered!

  4. Boring Rain says:

    1/2″ exactly in Boring.

  5. Jason Hougak says:

    We are counting on you Mark to keep us up to speed of the winter weather ahead!

  6. None here last night, but I think I’ll see something before this cold spell is over.

    This development is not a total surprise to me. Several weeks ago when there was much wailing and gnashing of teeth that Winter Is Over (TM), I just couldn’t believe that in a La Niña year (even an underperforming one) there would simply be no more chances for lowland snow the rest of the winter, particularly when it has snowed in the lowlands in late February and March before.

    The Dome was in full effect.

    35 degree rain, 0.32″

    Just looked at the weather report for White Bird, Idaho for next week….wow lows down around -4 degrees for several days. Glad I’m not going over until mid-March for the 11th annual Joe Wilson sausage feed where I meet up with old friends and make new ones. Got a little piece of property up above town between the Salmon and Snake Rivers…..don’t know if I will be able to reach it without a snow machine.

  9. Jason Hougak says:

    Looks like La Niña has finally arrived!

  10. alohabb says:

    So I’ll be in Seattle until Monday and by what I see , Sunday looks far better for snow there than In Portland??

  11. L S Morton says:

    East of Orchards we received more than 1/2 an inch of snow early on Feb. 14th 2018. It was beautiful falling. NE 137th Ave and NE 91st street, zip is 98683.

  12. JohnD says: from Cliff’s post this afternoon is compelling! (Mark’s friend at UW.)

    I slept through it all. My area really is contingent on the gorge. Work too darn much to wait on slush at 4am lol! That said, I am excited on the ensembles from the Euro. They’ve gotten colder. 😀

    Anyone know of a good website to see its runs? The one I
    prefer has been down for awhile now.

    Thanks in advance!

      Hi Jake, I know what you mean about the Euro. Been looking really good. There was a website you gave me were all you had to do was click on the state then the city and it showed I think 7 or 10 days (I don’t remember) to see the Euro. I booked marked it but awhile ago when I opened the link, it directed me to another site. I deleted the site because I thought maybe they just wanted me to pay for the site. Do you know what I am talking about? If so, could you tell me if they changed it where you have to pay or maybe the site was down. If so, could you send me the link again? Thanx 🙂

    • Jake in Gresham says:

      Okay thanks guys! That’s the only option I’m finding as well. Shucks.

  15. JohnD says:

    Really exciting stuff upstream! Let the games begin–and starting yesterday/last night–they already have!

  16. Jason Hougak says:

    Still some snow on the ground here. 34F
    When I was in 6th grade, I believe mid/late Feb. 1993, I remember our biggest snowstorm we’d ever had in Boring. We had just over 18″ and had no school for almost a week. At this point who knows what’s going to develop. One thing is for sure… the weather excitement has returned! 😁 👍🏼 👍🏼

  17. GTS1Kft says:

    1″ here @ 6:30am…

  18. Gina says:

    Fargerlake area in wa 3 inches 🙂 how do add a photo ? Thanks Gina

    Took a drive over the pass on 26 and then over to Keeps Mill Rd on 216. About 3 inches of snow and a nice snowstorm near the Camas Meadows, didn’t drive all the way down to the White River, just didn’t want to take a chance on getting back up out of there with heavy snow accumulating. On the way home came across a tractor-trailer jackknifed on 26 about a mile west of Blue Box Pass…had just happened and was blocking the west bound lanes…..called 911 when I got reception down to the gas station/convenience store just down the Hwy.

  20. Chris Butler says:

    1″ at Lacamas Lake in Camas.

  21. Tyler Mode in Battle Ground says:

    1″ at 300′ in Battle Ground. Lowest temp was 33.

  22. Jason Hougak says:

    Extended forecast looks very exciting… mooohoowahahaha!!!!

    • Ken in Wood Village says:

      I agree, keeps looking better and better. Just wish there was a little more moisture. It’s just me but I wouldn’t mind seeing a major snowstorm 😉

  23. ocpaul says:

    I got up to check at 3am, globby, wet snow with no accumulation.
    34.0 degrees @ 300′ in Oregon City. Can’t wait to see if the goods get delivered this Sunday and Monday!

  24. Ann Merklin says:

    At my house here in Salem, only wet grass! SO disappointed! Hope the mountains had a dumping! Still waiting here . . .

  25. cgavic says:

    sandy, oregon…..we suddenly had a snow storm beginning at 3 a..m. to 10 a.m. We live at 885 ft. now. Accumulated 2″ of snow. apparently the snow line was at 800 ft. All areas above that in the Mt. Hood corridor received the same amount. Ironically, after I called the nws in Portland who indicated the upcoming weather would only produce inches of snow for timberline lodge, and saw their depiction of colder than normal and drier than normal the second half of february…….The snow dumps on Mt. Hood and we get a valentine’s day surprise of snow….cool. People driving out here from gresham were surprised to see it.

  26. Jason Hougak says:

    Close to 3″ in the foothills east of Sandy.

  27. CJ says:

    1/2 inch on lawns and roofs, barely a dusting on streets and walkways at 800’, Eastridge Park in SE Portland

  28. Anonymous says:

    1.6 inches up here on Dixie Mountain at 1400 feet

  29. Jesse-East Vancouver says:

    Just about a half inch in East Vancouver (300’).

    • Jesse-East Vancouver says:

      All melted now but it was a nice surprise.

      • Diana F. says:

        Hey Jesse, howdy neighbor! I live in East Vancouver too, in the Bennington neighborhood. I stayed up until 3 am last night because Mark said it was going to snow.

        Then I gave up, because it started to rain, and I thought we were SOL. Woke up at 7 when the cat demanded entrance under the blankets (and her method include claws to the eyes).

        Weather geek that I am, took the opportunity to dash to my window sill.

        And SURPRISE! White was everywhere. Dreams do come true! SUCH a great surprise.

        Then I went back to bed till noon.

  30. Mountain Man says:

    6 inches at 1200 ft west Skamania county (Archer Mountain)

  31. Anonymous says:

    1/2 inch at 750′ on SW Schaeffer Road, Petes Mountain area of West Linn.

  32. Tracey Anderson says:

    1.5 inches on Prune Hill in Camas @ 700 feet.

  33. We had about 2.5-3″ in Rhododendron!

  34. Anonymous says:

    I had up here in Vancouver BC about 1.5 inches, maybe a bit more because of overnight melting. Up to 6 inches in regions east of here.

    • Roland Derksen says:

      Whoops- that was me. I wrote my name down properly, but my letter disappeared. In any event, looks like more snow is coming.

  35. prune hill outpost says:

    4 inches rural Washougal, 550 feet Skamania County. HEAVY, wet accumulation brought down several branches and leaned over several trees onto my road.
