I wish this wasn't so short before our overrunning system.

I agree. It is very similar to January 2004 in that regard. With that one the modified arctic front came through on the afternoon of the Sunday and the overrunning event was already underway by the next evening.

We picked up another 1/2 inch overnight. It's around 27 degrees and we've got some lingering flakes falling. So crunchy out there!

Love the lingering flakes….so peaceful

Yeah, my father in law is visiting this week. We were wanting to take him around Falls Park with all the lights they put up but decided we'd rather not risk getting frostbite!

And that's funny. There's been talk in our house of also doing the boiling water thing tomorrow, when wind chill values will get us down into the -40s. Always wanted to try it but never really had the opportunity. Might as well take advantage now!

I don't think wind chill plays a factor... the air temperature is all the matters with the boiling water thing.

[Blizzard777]

The ponds beginning to ice over…..something bigs out there! 
 

[Everleigh]

Down to 27.7* already. I ventured to Wally World and was happy that the roads are totally fine. There are snowflakes (?) just kinda....floating around the air. Very few, very small, but they are there! 

I am really, very concerned/worried about the potential ice Thurs/Fri, but my fam will all be home and we have a generator and the pellet stove, so....I guess we are ready?

Will be interesting to watch Roger's Pass station with this. It's definitely not in a typical spot that you would expect good cold air drainage and decoupling as has been discussed on here before. 

They are currently sitting at -28F with some of the coldest locations sitting at -32F in the state.

[Skagit Weather]

That snow cover really does wonders for dropping the temperature. 23F at midnight and 10.1F by 7:30 a.m. So I didn't quite drop into the single digits, but if we can stay clear tonight it looks like a good possibility. I think this is now the third coldest "event" up here since 2008 behind December 2008 and December 2021, but I may be remembering wrong.

[Timmy]

Looks like 12z gem and gfs, as well 06z euro have all gone away from snow initially at pdx.  Bummer, surface temps don’t look different but 850’s are

Well we are supposed to get down to between -15 to -19 tomorrow morning, so should be good either way.

[jcmcgaffey]

Thought for sure we would have seen at least a dusting overnight here in seattle but nothing fell. 

[TacomaWx]

Tonight’s gonna be real cold. Should stay below freezing today too. 28 at home.

Last night The Dalles spiked from 30 to 48 in about three hours when the wind switched to WNW. Then a few hours later starting plummeting over 20 degrees to 27 over the course of another 6 hours as the wind switched back to ENE. Pretty dynamic.

This airmass is a absolute Fukin beast. Looking at the obs around the area blows my mind! Oroville 0 degrees with a 55 mph wind!? bellingham 12 degrees 37mph wind, And just north of the bc mountains i found a -54. WTF

I did the boiling water trick at my cabin at 20 below and it is really cool.

[Brennan]

11* and clear. 

[awright-31]

GFS a little lighter on the ice. It thinks the warm layer is shallower and starts everything out as sleet. 925s would support sleet up until around 7:00 am in this area.

GEM agrees with the GFS but is much wetter.

ICON doesn't have a ZR map on WXBell but seems to warm up the 925s a lot quicker like the Euro.

[MR.SNOWMIZER]

Finally some real arctic air making it south. Bremerton 25 degrees with a 21mph wind. Was 23 at home. 

[LowerGarfield]

Only had .10 of an inch last night. Temperature has been steady at 15 degrees.

Picked up 4-5" here early this morning with the Arctic front. Dillion MT had a 26 degree drop in three minutes with the front!

Going to be interesting just how low we go! Currently -17F here with light snow continuing to fall.

Some current obs:
 

Havre: -31

Great Falls: -26

Cut Bank: -26

Helena: -18

Glasgow: -28

WE GOT A DUSTING OF SNOW!! WE GOT A DUSTING OF SNOW!!

[Everleigh]

Not as pretty as some of y'alls, but I'll take it! (My yard is a desolate waste zone. Apparently running a skid steer and an excavator around the yard will do that. Who knew? lol)

Friday will be crazy up there buddy. Closest thing to 1996 we have had up there maybe.

Another couple inches of fluff overnight.    If we didn't get into the warm sector yesterday with heavy rain and 40mph wind we would truly be buried here.   We got 3 inches on Sunday night and then 4 inches on Monday night which pretty much melted in the rain and wind for 6 hours yesterday morning... then got most of it back in about 2 hours around noon... and then 2 more inches overnight.    So 3+4-4+3+2 = 8 inches net since Sunday.    On top of 1-2 inches of concrete at the bottom leftover from the late November snow.    If all that heavy rain yesterday morning was snow we would probably have another 10 inches of snowfall and would not have lost the 4 inches... so a net 14 inch difference due to getting into the warm sector.

Anyways... it gorgeous now and I would love it to stay this way.   But we have 48 hours to enjoy it before the freezing rain arrives.   

I keep wondering what could have been too. I have no idea how long I had warmed to freezing rain but it was enough to wipe out our snow from the night before and jt was absolutely pouring. Guessing I'd be sitting at close to the 10 advertised by the Goofus but instead sitting at about 2 inches from the dumping after the temps crashed back down. 

[T-Town]

Daylight shot of the snow. A decent dusting.

Douglas, WY just went from 34 to 0 in one hour: https://w1.weather.gov/data/obhistory/KDGW.html

I'm amazed at the wildlife that survives that kind of cold.

Some of it wont. There will be a bunch of winter kill with this.

[TacomaWx]

Looking back on how this played out…overall it’s a better version of January 2020 IMO. The good stuff was mainly north of Everett with mainly light snowfall totals Seattle south. Biggest difference is the arctic air went much further south and it’ll be colder than it ever was then. I know they’re totally different events but in terms of snow the distribution is fairly close maybe a bit better south of Seattle this time with the big stuff north of Everett.

They had 3 feet of snow up there in the transition back in 1996.    I don't think they will get 3 inches in the transition this time.    Air mass is too warm to support snow by Friday afternoon.    Nice thing about Bellingham being so close to the water is that they seem to mix out quickly even though they also get the coldest air.

Yea. Not looking like a big snow event Friday even up north. Maybe 3-6” north of the Fraser out the valley.  I think the ice is going to be bad Abbotsford east. I could see it lasting through Christmas Eve out towards Hope. 

[ShawniganLake]

Down to 19F with light snow. Coldest of the event so far. 

[WildrootParable]

Wasn't expecting any precipitation today at all. It's not snowing hard, but it's definitely still snowing.

Would be nice to get a real transition event. Feels like that has not happened in a long time.

I guess it will depend on how warm the storm coming in actually is and how deep the arctic air is bottom to top of the atmosphere.

Down to 19 in Victoria as well. Winds are getting stronger and blowing the snow off the trees. Amazing that we have got back to back Decembers with this type of airmass. 

[Meatyorologist]

Lowest psun angles of the yeer twoday!

[Prairiedog]

I've dropped from 37 to 34.7 since about 5 am.  Gotton foggy out. 

[SilverFallsAndrew]

Whoa

[Rubus Leucodermis]

What a morning! 13.1˚F.

[MR.SNOWMIZER]

If this whole pattern had dug out just a little more sw over the ocean this would of been a epic blast for the entire region. Probable the closest we have been to a 1950 type seattle event since then.

Gorgeous. How much snow did you end up with?
