Rumors of Snow Fly Again; But Don’t Plan On Building A Snowman

9pm Thursday…

It’s a long evening here at FOX12 with only one 10pm show; good time to clean the weather center!  Now I see rumors of snow are flying around again this evening, so here’s a quick post to summarize.  Maybe more important…would some of you stay off those online shopping sites so I can get my shopping done here at work?  I can’t even get through to the one that sells large pallets of toilet paper and roast chickens, what is the world coming to…

WHAT’S THE STORY?

A weak weather disturbance moves overhead Saturday night, passing north across the region quickly.  It’ll likely be gone by sunrise or so Sunday.  There will be some light rain showers with this as it passes by

  • Models imply there will be little or no snow or freezing rain west of the Cascades; I agree.
  • That’s because there’s a good chance westside temperatures will be a bit too warm (just barely). OR, a few thousand feet overhead it’ll be above freezing, which means flakes would make it down to us as liquid rain drops.  If so, it would need to be down around 31 degrees or lower for those drops to freeze on contact (freezing rain).  That seems even more unlikely than snow since we may not make it down to freezing Saturday night.
  • There’s no chance this turns into one of those all-day snow or freezing rain episodes; it just isn’t that cold to start with.

The evening WRF-GFS gives no snow to lowest elevations west of the Cascades.

The latest ECMWF tries to give us just a little snow Saturday night, although temps stay above freezing the whole time…hmmm

The GFS & GEM models are like the WRF and say “nope, not this time PDX”

It WILL be cold enough for snow or freezing rain in the Gorge, at least east of Multnomah Falls.  I’ll keep a close eye on it and have a more detailed blog post tomorrow

    21 in SLE this AM with a DP of 18 at Noon. Probably a few flurries Saturday night but nothing big. Next two weeks looks seasonably cool and fairly dry. No Arctic blast, but no warm and wet pattern either. Highs mainly 40,s and lows mainly 30,s. Go Ducks. Peace.

    Coldest night here this winter at 18. Not bad I guess.

    The airmass over snow covered central and eastern Oregon has temps in teens and 20s. Road cams show a few locations single digits in the Cascades but generally 20s. Bend is at 21F on a road cam with snow cover and it’s 23F at my house without snow cover in the Cascade foothills. Must be some overcast keeping the temps from getting colder.

    Oregon Trip Check camera on 395 at Alkali Lake in Oregon’s high desert has had fresh falling snow all night into this morning. Thought that was very interesting to share. If you’ve ever been in that country it’s very desolate and barren sagebrush country.

    Soooo close…. 😦 oh well….

    Yeah, this doesn’t have the potential for much of us. I’m not gonna jump on the bandwagon. Hopefully we will hand a good shot at getting the goods this winter. We are almost to December and there is a lot of time left. I would be happy if December was mostly cold rain and building the snowpack.
