These PVs, troughs, and storms/storm tracks have trended all winter. I don't recall very much accuracy beyond 24 hours this year. This situation may, in fact, defy the seasonal trends and end up expertly modeled at 6 days, and the trough ends up as shown from 6 days and the storm develops as shown from 6 days and the storm tracks exactly as shown from 6 days, etc. But that certainly hasn't been the case much this year. Troughs and PVs and heights have almost always trended weaker/shallower/farther west all the way in. Maybe this one bucks, but IMO, it still bears watching closely.
Also, we may need to think about how we name monthly pattern threads next year. Fabulous February, Marvelous March, and so forth aren't getting the job done. We might need to go in a different direction with something like Delusional December, Jacked up January, February Failboat, March Mehness, etc.
