Elevation 580’ Location a few miles east of I-5 on the Snohomish Co side of the Snohomish/Skagit border. I love snow/cold AND sun/warmth!

I thought the east winds were going to prevent most precip in Puget Sound Lowlands? Gusts of 50mph possible down in North Bend tonight.

The NAM is showing about the same amounts in the Puget Sound area tonight thru tomorrow morning.

Thanks, that's what I was expecting. I had missed the range of dates on your initial post, my bad! East winds don't really roar too much up here compared to down in North Bend so looks like it'll be a fairly non-descript night out here. Fun to watch the snow reports down in Oregon and California. I've spent plenty of time in Yreka, Weed, Mount Shasta and Lassen NP, I'll be glued to the reports/webcams from there. 

Yeah I don't think the east winds are much of a factor tonight up here, more of a lack of precipitation moving north before morning in the north sound.  If dew points and air temp are low enough we could get some I spoze.

Radar shows precipitation over us but nothing getting to the surface so far. No east wind here at all which is surprising. 

Low dp and relative humidity may be the culprit, so the airmass is a bit dry. Even without the presence of any east wind. Radar may looked filled in but most of it is virga and tacoma is showing 72% humidity, so it’s close.

I think we will eventually see some flurries here tonight.

FWIW the 18z Euro thinks another ~1" or so in the post 4PM timeframe. But looking at radar it's not looking pretty and it's dead here now 1611723600-1YXRbEo4C0I.png

Looks like a little bit of precip is developing on the backside of the front along the central OR coast. May not be done quite yet.

18Z ECMWF shows the measureable precip just bypassing us this evening.   That does not mean there won't non-measureable precip (flurries) though. 

Top image is at 6 p.m. and bottom image is at 11 p.m.

Yup. It seems to be getting bypassed because the moisture is getting eaten up.

Drove up to around 700’ on Prune Hill where the roads were snow covered and there was about 1/2” on the grass.  Came back down to the 164th area where I am pleased to say it is sticking on the bark dust, grass and cars. Still coming down at a good clip too.

34, DP 30. East wind still going.

May still be more precip after this band and later tonight but temps should rise a bit after the steady moderate precip ends. That is pretty well advertised on most models. 

I still have about a half inch of slush and an inch on the grass. 33.3F, not really accumulating anymore. 

Just really nice to see a few hours of steady snowfall during the day after such a boring winter. Hoping there is more to come in Feb.
