The flow was similar to what's progged on models. It was super cold after that Clipper. One of the few times (only?) it snowed Aspen type powder here. The wind blew most of it away (and sublimated) the following day even though it was 7-8 inches here and stayed in the low 20s the day after.
I don't disagree with any of this. Most of your examples had robust shortwaves though and we are not seeing that in the long range yet. We might need a lee trough super Clipper scenario to score in the leeside areas. But that was an El Niño winter

Cold, dry NW flow. Trough orientation still too far NE. Mountains will have chances with clippers and NW flow but the rest of us will be dry unless that trough orientation changes and we can fire up the subtropical jet.
