Interesting, those were all backloaded winters here.
This December reminds me of 2014 and 2015. All-encompassing torches with blocking ridges in Canada.
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.
