January 2017 Observations and Model Discussion for the Pacific Northwest

[SilverFallsAndrew]

So PDX mixed out to 34 and its still 31 in Salem?! ****!

[snow maniac]

No snow here at all just 37 degree rain, another bust from NWS, This winter is really sucking here, a whole week of freezing weather and I can't even squeeze out a single snow flake.just rain, well I'm going back to bed now.

[jsf343]

Well when I hit the hay last night I thought this was over in my location (Larch - just under 2000') as temp had really started to go up (19 to 25 in 2 hours). This morning I get up and check and it's back down to 20 and east wind still blowing harder than when I went to bed.

Yikes

[FroYoBro]

31 and the east wind is back to being breezy here. About to get some pretty heavy freezing rain this morning. 

[Kayla]

Only 25º here with 40+ wind gusts and a whole lot of moisture coming in. Talk to you guys in a few days!

[Kayla]

So PDX mixed out to 34 and its still 31 in Salem?! ****!

 

Sounds like a sensor issue. Other sensors in that area are in the upper 20's to 30.

[Prairiedog]

I am back up to 31, the good news here is I will slowly creep above freezing overnight...Hopefully Salem does the same...I know PDX won't...ave youave

Have you made it above freezing this am?  I just touched 33 at 7am.  Same runny warm nose as yours.  Sucks. 

[FroYoBro]

Rain has started here and the wind is strong for this location.

 

Eastside locations of the metro area are going to get hammered this morning. Probably a lot of power outages coming up. 

[Prairiedog]

Holy cow, what just happened?  In 30 min I have jumped from 31 to 36f.  That frickin warm nose always, always moves up the flanks of the Cascades and warms me up while everyone else is cold.  Sucks!

[TT-SEA]

Holy cow, what just happened?  In 30 min I have jumped from 31 to 36f.  That frickin warm nose always, always moves up the flanks of the Cascades and warms me up while everyone else is cold.  Sucks!

 

 

Being above freezing today is a blessing.

You should be happy!

[EA_TTD]

Freezing rain has just started in Troutdale. Temp 28 DP 18 windE30 G40. Have a sick, sick feeling about today.

[Kayla]

12z NAM, GFS and even the RPM are now also insisting that PDX sees accumulating snow tomorrow morning. Models show that the cold surface air doesn't get scurried out much tonight then winds shift back offshore around 4am tomorrow morning while the whole column goes back below freezing.

 

There has been zero mention of it by the NWS or any of the local mets which is probably a good thing. Surprise snow?? Thoughts?

[FroYoBro]

Raining good now. Still 31. Just walked down to the road and it is completely covered with ice already. 

[Kayla]

Freezing rain has just started in Troutdale. Temp 28 DP 18 windE30 G40. Have a sick, sick feeling about today.

 

Yeah...this is not good. With widespread dew points still in the upper teens to low 20's we'll likely see a lot of wet-bulbing today keeping the temps down through the daylight hours.

[Prairiedog]

Must be getting some downsloping here as I've jumped to 38f.  Incredible.  I'd better get some evaporational cooling when the rain starts here or no ice for me, one year!

[jsf343]

Huge battle up here between cold air and warmer air, temps have really been bouncing. Rose 6 degrees in an hour then back down 2, pretty crazy.

[SilverFallsAndrew]

Yeah I mixed out sometime early this morning. 38. 

[SilverFallsAndrew]

Looks like above freezing at PDX,HIO, Aurora, and McMinnville now. That would appear to be good news.

[Trainwreck]

Wish I'd mix out. I'm way over it. Still 8 outside and sleeting

[Prairiedog]

Rain has started and temp has dropped back down to 36f and the wind has picked up.  some evap cooling going on plus the east wind is helping but a major battle going on here between warm and cold. 

[jsf343]

Where are you located P-dog?

[BLI snowman]

Definitely odd to see such uniform temperatures across the valley, with the gorge wind providing some downslope warming  at PDX.

 

30 here with moderate freezing rain beginning.

[Guest Dome Buster]

Wonder what the weather will be like in Sunriver the 27th-29th.   I will be there.

[Prairiedog]

Where are you located P-dog?

 

I'm between Redland and Estacada, off Springwater Rd on Clear Creek.  Little tiny community called Fischers Mill.  9 miles from OC, 9 miles from Estacada.

[luterra]

Above freezing in Corvallis as of 8:30 am.  Looks like we picked up about 1/10" of ice overnight.  May the slush begin...

[FroYoBro]

Up to 32. It looks like I will avoid any major ice problems. Should start melting soon. 

[Prairiedog]

I've dropped back down from 39f to 35f but I don't see it hitting 32 or anything below that now. 

[Jesse]

Yeah, the warming PDX has seen is due to downsloping.

 

Spiked to 32 here earlier, back to 29 now with strong winds and a solid glaze forming on everything.

[Jesse]

06z GFS and ensembles still looked good for another modified cold snap mid-late next week. Although the 00z Euro really pulled back on the idea.

[The Swamp]

36 here this morning in the swamp.

 

Had a nice moderate rain over-night to clear up the air quality.

 

Carry on.

[Dave]

This is a bunch of crap.  Still 28 degrees at my house.  Eugene is a giant ice cube.  Light zr still coming down.

[FroYoBro]

Lower level cold air loves to get stuck in Eugene. How much ice do you have?

[Blizzard777]

Hey, the weather channel actually showed Portland for a moment. I thought we didn't exist here on the west coast

 

Federal way 38.9 and green

[Deweydog]

Imagine if all the moisture today was snow!!!

[Jesse]

Imagine if all the moisture today was snow!!!

2008 but snowier.

[Jesse]

PDX running a mean temp of 29.6 through the first week of the month.

 

10.4 degrees below average.

[jsf343]

Definitely odd to see such uniform temperatures across the valley, with the gorge wind providing some downslope warming at PDX.

 

30 here with moderate freezing rain beginning.

 

 

It seems like that temporary though, temps around the normal wind areas popped just briefly but all seem to be going down again with e. Cooling going on.

[luterra]

This is a bunch of crap.  Still 28 degrees at my house.  Eugene is a giant ice cube.  Light zr still coming down.

This happened in December as well - despite logic and predictions to the contrary, Eugene was the last to switch to rain and the biggest ice winner (loser?).  I would assume it is part of the same phenomenon that makes the south valley the last place to clear in an inversion pattern.  Without enough of a push to mix the atmosphere, slow moderation leaves cold pockets in the most sheltered locations.

 

Also missed by the models and mets: 850 mb flow is southeasterly at present (southwest is more typical), which is eroding the cold air faster on the west side of the valley while leaving cold pockets all along the east side from Eugene up through Sweet Home.
