9pm Update: No Frozen Precip Metro Area Monday

9:00pm Sunday

Most evening models are in now in.  Nothing has changed.  Possible arrival of any precipitation is midday or beyond within the FOX12 viewing area west of the Cascades.  Another big question is whether ANYTHING falls tomorrow.   Our RPM model is dry over the PDX metro area all day and the WRF-GFS has a trace to .04″ by late afternoon.

There is one spot that COULD see freezing rain in the morning; that would be if the precipitation arrives right away 7-9am in the coast range valleys.  Especially south of Grande Ronde.  Even just west of Corvallis could be a place that sees some spotty glaze early in the day

Of course I’m being a bit dramatic with the 1% chance in Portland, but you get the idea.

One other spot where we may see a glazing is tomorrow evening in the Columbia River Gorge.  Both the WRF-GFS and our RPM imply some upslope precipitation running into the west/central part of the Gorge from Crown Point to Cascade Locks.  That would most likely be freezing rain, possibly ice pellets closer to Cascade Locks.  I’ll be keeping a close eye on that tomorrow afternoon/evening for you.

    You may have been wrong on this one, Mark..Snowing in Newborn past 25 mins. Fading but more precip on the way. Portland may not see anything but western Metro area might have some flurries, as we have already had in Newberg.

  5. Very dramatic fog this morning. It’s rising in tendrils from Puget Sound like steam from a hot cup of coffee. It varies from thin to pea-soup thick to low overcast. At one point there were tendrils of mist rising from the Sound backlit by a band of yellow-orange light from the rising sun under a blue-grey overcast.

    Blue sky overhead in Downtown Seattle, so it looks to be a sure bet to all burn off by noon. Radar shows any moisture to be well to the south of me. For those in the central/southern Willamette Valley: Have an ice day.

    Freezing rain/ice pellets Jefferson, OR…26 degrees.

    I wouldn’t know a model unless it was Gisele Bundchen, but I DO know there’s a narrow band of fairly active stuff that seems to be heading my way. Still 26.6.

    It looks as if Salem is just getting the leading edge and they’re still at 26 as well. Dan better hide under the bed…

    Freezing drizzle here this morning..

  9. Tyler Mode in Battle Ground says:

    19 degrees this AM.

    Not a bad stretch for no real arctic air.

    Low temps:

    26th: 22
    27th: 23
    28th: 21
    29th: 19
    30th: 19

    It was cool to experience the inversion setting in yesterday finally. After a sunny high of 53 on the 28th, yesterday was a sunny day but only 44.

  10. Rubus, I heard from one local forecaster that we have a chance of freezing precipt. here this evening. The last time I recorded freezing drizzle was on Dec.10, 2013. The fact is, the Fraser Valley does get serious freezing rain on occasion, but it happens less here because we’re closer to the coast than down in Portland or some other areas far inland.

    26.6 – coldest morning in a week

  16. A low of 17 and high of 30 at The Dalles today, with low stratus clouds in the Columbia Basin. So much for the “fakeness” in fake cold!

    • Mark Nelsen says:

      Wouldn’t you agree that this was a prime example of “fake cold” developing with no cold air arriving from outside the area?

    • But there WAS a little push of chilly air last week from Canada, that’s now over the Four Corners area. Not arctic air, but chilly nonetheless.

      Then we just had warm air move in on top of that to get the inversion and the low clouds. The same thing often happens a few days into an arctic blast. But yeah…given that the airmass that started this whole thing off wasn’t quite cold enough for lowland snow to begin with (if there had somehow been moisture that is), and that’s since moved out of here, it’s interesting how well the cold air effects have lingered long after the upper-level pattern has moved on.

  17. High Desert Mat says:

    -1 in Redmond right now at my place. Hopefully some of this gets out your way in east county. Maybe for Tuesday night? Doubtful but never know
