I’ll say again, not sure why we’re paying attention to GFS at all really. Multiple times over the last month it’s forecasted snow less than 24 hours out that didn’t happen. It’s been bouncing all over the place for weeks. I take it as a good sign that it’s somewhere in the general ballpark of Euro (there’s a ridge!  And arctic air headed generally south!) and then I move on.

Even the runs that look worse at the 500mb level still bury Seattle... its pretty much a constant now.  

How about 17 inches of snow in 24 hours.   😀

Up to 2" of ZR in some parts of Portland metro. Won't be many deciduous trees left undamaged after that.

I will gladly take 18 inches of snow in one day over that.

Remember when it was Saturday before that ?

It actually gets going Wednesday morning into Thursday morning.  

And that feature is a constant on all runs of all models now.   That is the big overrunning event and it seems pretty likely to bury the Seattle area.

I know... clearly the original progression has been slowed down significantly.    The ECMWF does get things going on Tuesday.    But the delay actually leads to much more snow up here as tons of moisture gets pulled in now.
