also spreading north?

Here’s the northern extent of moisture.

I took a walk around the neighborhood to survey the risky trees, branches over powerlines, etc. Did not look good. I think there is zero chance I'll have power if we get over an inch of ZR. It looks totally sketchy. 

Haha I’m just assuming we will. Have the batteries and generator ready to go, but could be scary for a lot of folks. I’m not sure most people understand what’s coming with the wind chills.

I don’t know much about PDX climo during these setups, but I’m surprised the models are saying Ptype is an issue given the depth of the arctic airmass and high ratios expected. Is this typical for these types of setups?

Not an expert but models never seem to deal with these setups perfectly. I have to believe this is all snow for most - maybe south metro deals with some sleet. Definitely a range of microclimates and wide spread of totals for most events. But we’ve had all snow with less impressive cold in the past.

I've been scheming for a good way to save everything in the fridge. I think that if I put it in a cooler and then put the cooler outside, that might work (to keep it above freezing). It probably won't be cold enough to save the stuff in the freezer though. Looks like I'll be firing up the grill in the cold.

So I’ve been following folks believe ratios will be higher than 10:1 in this setup. Basic explanation as to why?

[SpaceRace22]

The 00z HRRR says it stays all snow with NO changeover to sleet for basically everyone north of Tigard/Lake Oswego. From Wilsonville to Tigard/LO, the changeover is very brief and more than made up for by heavier precip.

The HRRR is fairly useless this far out, but I've got a good feeling about tomorrow still.

[MossMan]

Currently 11.8 degrees. Had a daylight high of 18, a midnight high of 20. 

[Phishy Wx]

tanking now, down to -3

[OysterPrintout]

Just got back from a walk along Division and it feels like the real deal out there and I refuse to believe it could possibly warm above us tomorrow.

[Port Angeles Foothiller]

Officially the lowest temp I have experienced here since I moved here in 2017. Wonder how low it gets tonight.

It also flips precip back to heavy snow at Salem tomorrow evening. It’s also important to note this model is typically very aggressive with WAA.

[SilverFallsAndrew]

Down to 23 at Troutdale. I think PDX can do it!

You are going sub zero

[GHweatherChris]

Anyone got a link that will let me look up certain locations all time low temp records?  I used to have it, but don't on this computer, thanks in advance.

[Doinko]

Wow, PDX down to 25 on inter-hour obs

[MR.SNOWMIZER]

High of 17 here at home and currently 13. Going to be many sub zero readings in western Washington tonight. 

[Weiner Warrior]

NAM looks nasty

Hopefully they get below 20 by midnight, that would be great

[GHweatherChris]

NAM bumping north it looks like.

[Rubus Leucodermis]

12.2˚F.

[MR.SNOWMIZER]

Nam further north some and stronger

[Sunriver Snow Zone]

We were 32° at 5:00 and now its 12 degrees, that's a quick temp change! 

[GHweatherChris]

Do you think all the snow that will make it up this way tomorrow will actually stick?

[TeacherLori]

15 degrees here in Lynnwood. We may have hit 20, but most of the day it was 17 today.
We got 1.5" of snow yesterday and we still have a nice layer. I'm happy.

HRRR is an extremely useless model, in setups like these it always shows the temps WAY too warm. Only thing it's good at is forecasting my snow totals, although it still rarely gives me enough snow.  Every other model often gives me half of what I end up getting.

Probably, but blow around too.

[Rubus Leucodermis]

Definitely was a beautiful day with wall to wall sunshine, a little snow on the ground, and the mountains plastered in white. But COLD. Did a few errands and it was always a shock to step outside my Vancouver home and be greeted by Rockies temperatures.

I think it’ll definitely get as far north as you and OLM. Fighting some dry air for sure this far north…but overall banking on models tendency to be too surpressed still.

11.5. Most likely single digits within the next few hours…3 winter seasons in a row of single digits at my house?? incredible! Before that last time I had single digits was 2008, and before that it was probably 1989?

You know this airmass is serious when places with east wind are colder than places without it.

[Omegaraptor]

Decided to drive up and spend the weekend back home in Portland metro to ride this one out. 
 

25 at PDX, 28 at HIO

My local fire department warned the town that 40-60mph winds are supposed to be churning through sky valley tonight. Might drop to 4...long shot for negatives.

[Mercurial]

-58F forecasted for White Sulphur Springs tonight.

I've been thinking about this the last few days.  We are getting into very rarified company with some of these stats.  A couple from MBY.

This will be the 4th consecutive winter to have 2 or more freezing max temps.

Third consecutive to have a max below 25

 

Both have not happened in a very long time.

Mossman didn't get snow. Not impressed.
