Tonight/Tomorrow Snow Outlook

Here is what I’m going with this evening (from our Facebook page this afternoon):

SNOW FORECAST FOR LOWEST ELEVATIONS
Steady rain changes to mainly heavy/wet snow after 8pm, could see brief sticking snow in the hills and east of I-205. Unlikely to affect traffic, except up around 1,000′ and far east side (Gresham, Estacada, Damascus, Camas, Battle Ground).
Snow showers off/on Wednesday……ZERO to TRACE accumulations.

SNOW FORECAST FOR HILLY AREAS UP NEAR 1,000′
This includes upper West Hills, Mt. Scott, hills around Gresham etc…
Rain changes to snow late this evening, could stick with a TRACE-1″ towards 10pm-Midnight. Then snow showers tomorrow with TRACE-1″ additional snowfall. No big traffic issues, but definitely so…me snow on roads for AM Commute up around 1,000′.

SNOW FORECAST FOR 1,000’+
This includes highest spot or two in West Hills, Sandy, Northern Clark County Hills etc…
Rain to Snow later this evening…1-3″ on ground by daybreak. Snow showers with another TRACE-1″ during the day tomorrow. Total 1-4″. Above 1,500′ up to 5″ is possible.

But here’s a big issue.  Anything after midnight and through noon will be showery, so I could easily see one spot getting an inch near sea level, while 5 miles away the same elevation gets nothing!  Another reason not to go with the 500′, 750′, 800′ wording that seems to be so popular nowadays…

    Nice little snow shower just passed through. Finished with a burst of graupel.

  4. Woke up to approx a half-inch of the white stuff. Melting away quickly…34°….

    Might hear some thunder from a stray AD this am….

    I’m ready for some drier weather….especially when it adds cold, blustery east winds to the mix….

    Should be some cold overnight temps starting this evening…

  5. Brad says:

    8 a.m tower temps cooler at T2 and T3. T1 pretty much flat (up .1 C). Could be an interesting day as sticking snow has been reported in Clark Co. as low 200 ft. Might see a stray albino donkey today too?

  10. KeizerGuy says:

    Snowing in Keizer (not sticking) right now

  11. PaulB/Eugene says:

    Snowing at 650′ elevation S of Cottage Grove on I-5….same on Coast Range west of Salem at same elevation…saw flakes on the traffic cam S of Albany on I-5.

    Looks like Sandy forecast idea verified….did someone say 5 inches plus on ground?

    Don’t know how much fell E of Salem, in Colton area.

    Looks like plenty of showers until early afternoon…best S of PDX. Will probably snow some around Eugene…sticking if lucky later this morning.

    • We have 3″ on the ground in Gates this morning at 1,000 feet…35 miles ESE of Salem. The rain switched over to snow at Midnight. Our forecast pretty much verified. Sorry it didn’t get lower last night.

  12. Tyler in Battle Ground says:

    Beautiful blue skies here after a little bit more snow! Looks like a nice few days ahead. I am so beyond ready for some dry weather!

  13. markp427 says:

    Woke up to heavy, wet snow falling in Orchards – covered everything (roads, rooftops, grass) in white. No more than 1/2″ but still, it’s something. Dec. 29th is a lucky day for snow, it seems.

  14. pappoose in scappoose says:

    The slush on my vehicles has turned to solid ice.

  15. kcteach-Gresham-500' says:

    Like a faucet turning on, just switched to big wet flakes…then back to rain. What a difference a few degrees make around here.

  16. HeatherWeather says:

    Snowing slightly in NE Portland by Airport 34.1

  17. Steve in Beavercreek 1,100' says:

  18. Karen in Camas says:

    Snowing hard in Camas (Prune Hill)…snow on the ground too! 🙂

    • camas mom says:

      Karen, where on Prune Hill do you live? We used to live in Summit Oaks Estates before moving to Livingston Mountain….

  19. camas mom says:

    Obviously, we have snow. 🙂 Snowing currently and about 1-2 inches on the ground. Have to take my daughter for a sports physical – OF COURSE. ha!

  20. pappoose in scappoose says:

    Snowing in the Fruit Valley area of the Couv right now – big huge wet flakes, but I got to wake up to snow!!!

  22. Christina says:

    Ridgefield @ 120′ with snow! A nice dusting on the ground already.

  23. Muxpux says:

    Rain/snow mix in Longview, come on snowflakes, win this battle! Keeps bouncing around from mostly snow to mostly rain

  24. kcteach-Gresham-500' says:

    Switching between around 25% snow to about 75% snow. Probably total switchover if that next cell reaches me.

  25. pappoose in scappoose says:

    Slushy windshield alert. KGW met informed me it’s a “Elevation Event”…please stop.
