Higher elevations of the Santa Cruz Mountains tend to get an accumulating snowfall every other year or so. Unusual, but not super-rare, either.

I'm betting it will go really low.

Impressive 2 day totals through Monday evening.  This includes 3 different shots of snow.

Lowland snow Monday night with temps easily cold enough for snow according to the ECMWF.  Tons of chances coming up!

I do think that the snowcover could certainly help us entrench a fair bit more cold in the metro area. Gonna be fun to see how low we can go in late February.

Really nice outpouring of cold air right now.  Sumas is down to 24, North Bend 27, and here 28.  All with wind.  Feb has been insane lately!

Surprisingly calm here... must be a gap wind.   I am sure its more windy down in North Bend.

Dewpoint is down to 10 at SEA.

Really nice ECMWF run!

It might not warm up too much... but 850mb temps will be significantly different next week compared to what we have right now.

00z definitely more encouraging for the weekend snow in Seattle. Not sold yet because of how burned we've been this year, but this was a good run. Curious to see what the EPS says for the next 7-10 days. If it's anything like the operational and/or the GEFS, it should be a good run with snow chances.

I think that band of snow curling in from the west down south might make it to the SW side of Portland.

Also significant enhancement on the radar from Tacoma to Olympia and around the Kitsap Peninsula right now.    When you run the UW radar loop it looks like the energy from the old Portland deformation band has translated north.

Based on the ECMWF... there are lowland snow chances on about 6 of the next 10 days.

Even Coburg appears to have sticking snow. As of now, it looks like the only place in the WV to get skunked is Eug/Springfield. I haven't given up hope yet though.

It s hard to tell, but it looks like this band has set up just north of Eugene.

Actually closer than I thought... snow does start in the Seattle area between 8-9 p.m. on Saturday.

Nice! Though I’m hoping this isn't the start of a trend to bring that storm in earlier. It would be a bummer for my flight to get canceled or redirected so then I miss out on the Sunday snow. Especially since it looks better for the Puget sound region.

Impressively snowy in the Puyallup swamp right now!    That area seems to be right where the moist air is hitting the dry outflow.   To the north of there it looks dry.    Also snowing pretty good around Tacoma.

Wow!  The ECMWF shows 10 inches of snow for SEA over the next 10 days.  Besides that it spits out a 38/22 next Tuesday.  That's new!

If I had to choose an analog to this it would be late Feb / early March 1971.  A lot of comparisons regionwide.
