Winter Storm Watch: Western Lowlands of Oregon Thursday

The NWS has put up a winter storm watch for most of northwest Oregon.  Remember a watch means something COULD happen and we’re WATCHing it closely.  You can read my posting below for a bit more detail.  Here is our forecast (as of 5:30pm)

This is enough of a risk that if you have a choice to drive a “snow car” or “non-snow car”, take the one that can handle snow for Thursday.  For sure do it from Salem south.  But even here in Portland.  There is an unusually high level of forecast uncertainty on snow amounts here in the metro area tomorrow, so I assigned these percentages to several “events”:

There is a very good chance this forecast will change as new models come in between 8pm and 10:30pm.  If those models come in much wetter like this morning’s ECMWF, my snow forecast is going way up for the metro area.

Stay tuned!

  1. its snowing in battle ground

  2. Andrew (Near Silver Falls 1600') says:

    Temp has dropped to 14 under mostly clear skies here. I’m in a wind sheltered location and the snow cover helps. Clouds increasing.

  3. Snow89 says:

    ECMWF is further north with the moisture, even up to SW Washington now.

    Blizzard Warning issued for western Columbia Gorge.
    Winter Storm Warning for entire Willamette Valley, into Clark County
    Per PDX AFD.

    Enjoy

  5. paulbeugene says:

    I would just as well issue the Winter Storm Warning for the entire Willamette Valley. The majority of lowland locations will probably exceed 4″ , just a matter of when it happens.
    Just looked at the HRRR 4z output. has emphasis (based on looking at the 700mb vertical velocity looper) for best precipitation totals over Corvallis to Eugene-Cottage Grove. 2′” of snow on ground by 11am Corvallis, Eugene. Nothing on ground yet as of 11am north of Woodburn on 04z HRRR.

  6. Taylor says:

    Temperature here is struggling to get below 19 degrees. Probably the east wind is to blame with that.

    • Benjamin (West Salem) says:

      You know it’s cold out in western Oregon when people are saying things like “struggling to get below 19 degrees.” lol I LOVE IT!!!!

    • Jake-(Gresham) says:

      Yeah I’m currently sitting at 22F but with the wind out here it’s still brutal!

  7. paulbeugene says:

    If I use the point and click forecast on NWS PDX page for Eugene I get a range of 10-21.5 inches of snow through Saturday. I am not sure that will verify..for whatever it’s worth

  8. Jason Hougak says:

    It’s a thing of beauty… check out the color on the watches and warnings map. Outside temp. 16.5 and 14.1F from my 2 thermometers. High overcast coming in.

  9. dman says:

    So I hear a lot of snow for every where!!! But where does the Dalles fall into this for cast i have been waiting for snow all winter!!!

    Please please someone tell me good news!!

  10. Jason Hougak says:

    What a winter for Eugene if it gets rocked again. December record cold/snow then Feb. cold/snow. Flat landers will have to dub it the snow and cold capital of the valley.

    • Eugene Dave says:

      It feels like Christmas Eve as a kid right now. Much anticipation! Hope to not receive a lump of coal.

  11. paulbeugene says:

    Euro still gives (through Sat) max snow to Eugene, 7.4 inches, with nothing less than four inches N to Longview
