17” here. Wowzers  

Does that convert to many Canadian centimeters?  

[MR.SNOWMIZER]

The difference between the euro and gfs is disgusting.  Not excepable for this close.

High temps Wednesday... partly to mostly sunny day around Seattle and northward after lingering snow showers move south before dawn.

Going to be too warm up here again, especially with my hopefully deep snow cover. Most likely mid 20’s for me like today.

Heavier band headed towards Seattle

Was watching that. Hope that hits King County head on.

The Euro is on an island with precip totals. It also performed the worst for my location in early December also. 

[TigerWoodsLibido]

Down to 35F. Nice evening. Cloudy and dry.

43. Glad I upgraded my measuring sticks to 40 and 100cm devices in recent years.

All comes down to track of low... heaviest precip will be to the north.    Sort of like what we are seeing tonight.

I agree. You'd think there's a middle ground for these two major models. I  don't care which way it leans, there needs to be a middle ground. Just absurd.

High temps on Thursday.

Think it could get interesting for a second

[Winterdog]

Still 28F here.  I'm up to 1.5" with very light snow still falling.  Not expecting more than another half inch out of this thing tonight.  It's been very light since around 5pm and it looks like it is just about spent.  Still hoping for some frigid temps.

So what you're saying now is even at this range, the models can't come to compromise on the track of this low? Is this acceptable?

[Doinko]

Euro definitely is wetter with the system on Thursday/Friday

I’m going for 22 for a high!

[Snownerd3000]

Snow holed in Woodinville 

[TT-SEA]

850mb temps go above 0C early Friday morning... that is when freezing rain becomes an issue if there is cold air trapped at the surface.   Should be no freezing rain threat until that time.  

[Cascadia_Wx]

Metro area developing ESE winds as colder air starts to get pulled through the gorge ahead of the offshore low. Down to 35 here with the DP down to 30.

Too bad the low moving in to the north tomorrow is going to switch gradients back to southerly through tomorrow evening and delay the whole progression 36 hours or so. Wouldn’t surprise me to see PDX make a run at 50 tomorrow. Would be nice if we were going into the cold air for event right now.

Hmm I might have spoke too soon, still looks way drier than the other models

It was about 5 degrees to warm today for my area and 9 degrees to warm for Bellingham.  It was real close to Seattle though.

Imagine if Snoqualmie was as good a cold conduit as the gorge 

[TacomaWx]

Some slush building up on the cars now.

[WildrootParable]

It's finally happening! For the first time all day, we've switched over to bigger flakes. I'm thinking it's because a nice big band of green passed over us on radar. 

[joelgombiner]

Yukon update: 

Mayo Airport -56 F, 1055 mb 

Watson Lake -53 F, 1053 mb

Deadmen Valley, -52, 1052 mb

 

[MR.SNOWMIZER]

The straight and Vancouver Island are going to get one for the record books.

Good sign for tacoma!

Calling it a night. About .25in on elevated surfaces and still snowing. Wishing for a GFS miracle. See y’all at 5am!!!!

Watching that come right towards Seattle we need heavier precip rates please! Almost looks like a mix here in central district currently

It's not drunk tonight? 

[OysterPrintout]

Step back from 18z for us. 850s warm real quick on this run. Imagine there will be a good deal of waffling on whether or not snow happens on the models basically all the way up until the event.

The pass would need to be about 2,500 feet deeper so it comes in at valley level... but yeah that would be a huge change in the climate of Seattle.   

[Cold Snap]

Just measured an inch of snow from this event. Total snow depth is just under 2.5”.

[thisisacreativename]

Rooftops and cars turning white here. Visibility has dropped a noticeable amount too.

It’s coming down fairly good…if it keeps up it may start sticking. Radar is looking more impressive to the west.
