ECMWF looks more suppressed again with the trough next weekend.   Precip is generally farther offshore and farther to the south of the Seattle area than the 00Z run.   There is some precip on Saturday but Sunday is basically dry on this run.   

Total snow for next weekend (had to use 10:1 ratio map to get 48-hour total).

New member here. Have been a Washington resident for 6 years now. Glad to have found these forums because I love talking weather. I bought a place in the Port Angeles foothills, 1000’. We get some serious totals, 2019 was the best. I got shadowed from last nights event, but I’m optimistic about tomorrow. 

Welcome!   Really awesome to have a poster up in that area.

43 here, very nice day! Snows hanging on for dear life in the shade but with a DP of 36 and breezy SW winds it won’t hang on for long. Really liking how it’s looking for Monday night-Tuesday. That looks like it could be a bit snowier than last night, and the snow might have a bit more staying power. Will probably be some snow on the ground to start spring off!

I’m just good with the active weather regardless.  Been fun this year with all our chances.  Been years where absolutely nothing falls.  So this has been a real treat! Gorgeous out now ☺️

39* with south winds still blowing 15-20 

Yeah, I’m hoping we can somehow manage 2-3 inches tomorrow night into Tuesday morning. Should atleast get another 1”. Still haven’t had a significant snowfall this winter but it’s been great regardless. We’ve had so many 1/4”-1” snowfalls this year…actually pretty remarkable how many times it’s happened.

ECMWF is a little farther south... notable improvement for the Seattle area for Tuesday.     Models seem to be converging on the same track of the low.    The devil is in the details in terms of precip amounts and temps.

Love seeing the ECMWF getting better!  Looks like it might be fun.

I managed to get 3 inches in one shot Nov 30 - Dec 1, and have had many smaller snows.  Quite impressive as you say.  A nice 3 to 5 inch shot would round things out very nicely.

I ended up with 0.6" last night.  Right when things really stating getting good the mid levels warmed too much and it turned to slop.

Taking everything into consideration and grading on a curve I give this winter a B so far.  Besides the snow, the number of solid cold waves we've had has been quite impressive, and amazingly it still looks cold 10 days from now.  I can't imagine this winter ever getting above a B+ when you consider the all time greats of the past.  I suppose a top 3 or top 4 March could make it an A-.

ECMWF spits out a 38/20 on Wednesday with snow on the ground for SEA.  Very top drawer!

It also shows a possible snow event next weekend.

The worm has really turned this winter.  We'll see if it holds.

WRF-GFS is picking up on this also 

A80AAB70-4864-4B4F-992F-7DDA8D7B2585.gif

The thing I really like is places that didn't do quite as well last night get some love with the Tuesday system.  Looking at the mid levels 850s are a solid 1.5C to 3C (depending on model) colder than last night south of Seattle.  That is a huge deal.

It is so weird where I live.  Last night I was getting better quality snow when it was 34 degrees than I did when it was 32.

You get some pretty juicy upslope events there when the Fraser river outflow is cranking.  Pretty good fetch between there and the coastline around Vancouver

Yeah, November 30th-December 1st has been our top event this winter so far. Fell in 2 separate rounds but we had about 2” the morning of the 1st. There’s a chance Monday night could end up being the biggest snowfall of the winter…but right now I’m thinking maybe just a bit more than last night IMBY.

I really hope tomorrow night can over perform. I’m disappointed in how last night went. Started off pretty good but by 3am was pretty much over.

Looking like Tuesday and Wednesday might be sub 40 highs. Looks like DPs stay below freezing so the snow shouldn’t melt in the shaded areas for a couple days.

Pretty intense c-zone just formed over the last 20 minutes from North Seattle out through Monroe and Duvall. 

@Cold Snap is it snowing there again?

I just woke up but I also woke up around the time of that convergence zone for a bit to see if I had gotten more snow and it didn’t look like it and it was a very wet snow that wasn’t really accumulating like it was earlier in the night. Though I do not have a roaring SW wind right now winds are actually quite calm IMBY.

For sure.  When the visibility suddenly rose last night I knew the snow had become very wet.  Could have been way better with just a slightly colder air mass.  Tuesday morning has serious potential.

I'm really excited about this one.  Legit cold air sweeps in on Tuesday and then a hard freeze Tuesday night after the snow.

2019 was an amazing upslope event! 34” the first snowfall with 58” total over a 8 day span. I had snow on the ground until mid April
