It definitely won't be as cold in the east due to the PDO, agreed, but that doesn't necessarily preclude a good snow-stretch. I get that the PDO is most highly correlated to temp late in the season, but it's also unwise to ignore what will be a very disturbed polar domain. Most of the shitty snow years in your data set had a very strong PV and given that we won't see a record trough down to Baja like we did last year, that will matter.
