If tonight isn't our coldest night of the winter, that would be seriously impressive.

This is a deep airmass (deeper than modeled), with clear skies and the longest night of the year after the shortest day. Just about the best case scenario you could imagine.

Hopefully this bodes well for the tomorrow night stuff. Would love to see more snow and shortens the ZR duration.

Snow cover too. We didn’t lose any snow today in my area. 

[Meatyorologist]

Holy crap, temperatures are dropping like a damn rock. I keep refreshing Wundermap every 10-15 mins, and it's around 0.5-1F colder across the board. Maybe we hit 19F at my place before 5pm?!?

Forgot to mention that. Snow is an amazing insulator. Tonight may be the coldest all this century given global warming.

Poor man’s 2005! 

no Snowbows unfortunately though

[TeacherLori]

Today held steady at 23 in Lynnwood. Right now it's 22.

[lowlandsnow]

Looks like one station in Winthrop didn't make it to 0 today

[TacomaWx]

Today was drop dead gorgeous. Didn’t lose any snowcover today. Tomorrow nights gonna be really interesting to watch too. Potential for a very interesting but unfortunately damaging ice/snow storm. We missed out definitely with the big storm yesterday but it’s been fun quite the blast of cold air.

The benchmark this century for KSEA is 14F in 2008 and 2010.

We could potentially get there.

The predicted low for KSEA on the NWS website is 15. I think it's doable.

Yeah the number I’m hoping to beat is 14F in November 2010. Could very well do it will probably be in the teens before midnight. 

[Phishy Wx]

Currently 7 feels like -2

[Meatyorologist]

I wonder if KSEA will have a sub-20F tomorrow. Hasn't happened since February 1989. That is my personal benchmark for what consitutes a top-tier airmass. That and single digit lows.

[awright-31]

Projected ice accumulation at OLM according to the last 5 Euro runs:

18Z yesterday: 0.29"
00Z today: 0.33"
06Z today: 0.41"
12Z today: 0.47"
18Z today: 0.55"

This is not looking good for the South Sound.

NWS going on the lighter side and once again against the guidance of the EURO…hope they’re right this time.

I’m already at 12 degrees, single digits should be a cake walk tonight up here. 

[Kayla]

Already down to -29F here which is a new record low for me in my 6 years here. Skies are already quite clear and winds are slacking off. Pressure already down to 1056 mb.

Thinking we may even make a run at -40F here tonight. BZN is already down to -24F and MSU is also down to -24. All-time records for those locations are -46 and -43 which are amazingly under threat tonight.

How cold did you get last year?

 

[NWbyNW]

Some more scenery from today's beautiful weather.  Currently 24F here at sea-level.

23 at BFI… 21 here.

I’m betting the models scour it out too quickly. I’ve got a bad feeling about this one. We haven’t had a significant ice storm in almost 11 years so it would be damaging.

Likely pretty top tier regionally if this had just scooted a tad more SW.

The daytime high of -8 at Kamloops today is extremely impressive and looks like their coldest since 12/29/1990.

The fact that this pattern is occurring the exact same week as 1983 and 1990 makes it a lot more difficult to break records across the West. Still, looks like many places may see their coldest highs and/or lows since then.

If it had happened a week earlier, lots of records would be falling.

Not sure if I will beat it but it will be close!

Will be tough unless winds calm and skies stay clear into early morning.

[gusky]

22.1F at my station. Quickly approaching my station's all-time low of 19 (Jan 1st, 2022).

Yeah I’m preparing for the worst personally. Heading to the store in a bit. Done betting against the EURO.

SeaTac is up to 22

That would be amazing, but something tells me we score a low 20s high around 11:53 PM.

Down to 21. You make it to 19 yet?

Those 21s on the inter-hour readings are just rounded and are very likely readings of 22. 

[Kayla]

Temp now down to -31F!

Yeah I think I’m going to as well later this evening. We could very well lose power at times happened during the last storm. This isn’t modeled to be quite as much as 2012…but would be very bad still.

31 at PDX!

My sister used to live in Highlands Ranch! Lovely area.

[MR.SNOWMIZER]

20 below places in the Okanagan highlands already.  Some places will be close to 40 below.  18 degrees at home already!

This is going to be more snow than forecasted. I can feel this one.

I love your positive attitude. Life is better with that kind of vibe..
