Sprinkles and Flurries This Evening

A few light showers are moving down out of Canada via Western Washington this evening.  Sticking snow level is around 1,500′, which means any of us could see flurries mixed in.  Around 3pm I had all snow at my home around 1,000′ in the western Gorge, although not sticking.

As the disturbance moves directly overhead from 5-9pm, a trace to 1/2″ is possible above 1,000′ in the Cascade foothills, a little heavier precipitation might bring the snow level as low as that.  But that’s about the best I can do, skies clear later tonight for lots of fog and low clouds late.

    Well it sounds like winter storm flurry blasting thru the PNW tomorrow woo hoo! “It’s a start”

    Sure is cold out, just got back from Portland. It was 36 when I left here about a hr or three hrs ago and now it’s down to 27 ground is all frozzen to.

  3. Would you believe that as of 10pm it’s down to 22F at The Dalles airport? The “homegrown cold” spell is beginning to sink in here…

    Perfectly timed clearing here in Seattle. Stayed cloudy much of the day then cleared off right before sundown. Temperatures are now lower than their forecast overnight minima. If the inversion stays together, looks to me like it might not make it out of the 30s tomorrow.

    I think we are heading in the right direction for arctic blast, I see no sign of a warm sw flow at least. Thanks for the encouragement Paul:)

      I’m expecting one in the latter half of January (my forecast is for it to happen sometime from the 10th to the 24th). So the latest la-la-land model runs have me feeling optimistic.

    Brief comment:
    00Z GFS Ensembles for 850mb temps….at 300hrs..lala land of course…the ensemble mean is up to 5C below normal…that is the largest (coldest) discrepancy of the last four runs…so the trend is still there…..don’t get rocked but the variance of the operational runs but at same time keep tabs with reality….even I have trouble with that at times.

    Latest shows hardly any moisture right around the peak heating of the day tomorrow.


  8. Marcus says:

    What about the GEM? Not sure when that run comes out!

  9. Tyler Mode in Battle Ground says:

    Winter is always just ten days away!!!

    I remember back in late February a few years ago the models started saying cold and muse snowy ten days out. It was hard to believe. However, with the late February sun it turned into a cold spell with a nice few point drop, but not any snow.

  10. 00z GFS = Winter cancel, well for the next 10 days at least. LOL. Only things we need to concern ourselves with is brief Snow/ZR if any moisture survives and then once this pattern starts to break down an overrunning Snow/ZR event down the road.

      No epic snow event then huh

    • Marcus says:

      Hey rob wasn’t the ensembles still on board with the cold tho.

    • There could easily be an ice storm PDX > East in near future. I expect models are trying to moderate the cold pool too soon and especially weakening offshore gradients prematurely.

    • Benjamin (West Salem) says:

      I think that the ensembles for the 00z come out in 45 min. I would be curious to see if they are still on board, besides even if we do get an arctic outbreak it is quite likely that there will be many more of these let down runs of the GFS.

    Latest from the NWS on tomorrow:

    National Weather Service Portland or
    853 PM PST sun Dec 30 2012

    Models are having a hard time with the Monday system…with major
    changes from the way they were handling the system yesterday. Now the upper trough is splitting Monday morning…with the low center about 75 to 100 nm west of the Columbia River entrance. At 00z Tuesday it becomes a closed low…diving south along the Oregon coast or just inland. Morning dew points will be in the middle to upper 20s in most inland valleys and increasing cloud cover will limit heating. Thus… wet-bulb temperatures likely to be near freezing which would favor snow. The low enters northwest California around 06z Tuesday. Expect clearing from the north overnight.

  12. I washed and waxed my car today, so any moisture that wasn’t forecasted was my fault.

  13. Marcus says:

    00z GFS looked like it just pushed back the cold to 10 more days its just messing with us:/
