I’m not buying the east models at all (nam, gfs, icon). In my opinion there are several factors that favor the western side of the envelope.
1. The ridge axis is over Idaho, which i believe is even more west than the Jan 2015 blizzard.
2. The ensembles are west of the op
3. This is the most important one, the Navy, notorious for having a progressive bias is west of all the models I mentioned above. The rule of thumb I use with the Navy is I straight up ignore all guidance east of it. If the progressive biased Navy thinks this is coming up the coast, in my opinion it probably is. In fact, a blend of the big 3 is west enough that even my area could see precip type issues.
