Saturday looks dependent on dynamic cooling with the precip rates being decent right off the bat before WAA quickly jumps the snow level up. The UW-WRF does have flakes down to sea level briefly in BC but I wouldn't count on it. It's going to be brief.
And then Sunday the snow level will be well above the passes again. Just a brutal stretch for getting ski season going, although the Euro shows an occluded front followed by a decent postfrontal period about a week out that would finally allow for some decent accumulation. The webcams at Snoqualmie don't look terrible so they should be open by next weekend at least.
