Yeah the mechanics of this event are much more robust....but everything has trended more progressive/flatter from about D4-6 in this pattern. Starting with that 12/28 event. That was a 55F cutter to powderfreak 4 days out....same deal with this 1/4-5 event. Barring some other offsetting trend in the synoptics, I'll bet this one ends up more progressive too....it won't be enough to eliminate the storm though because it has a pretty nice looking shortwave...it will still be a good storm for a pretty good area, but it wouldn't surprise me if it tames a bit on total QPF and ends up more east than what it shows right now.
That said, there could still be something to offset the progressive trend...maybe the upstream ridge becomes more amped out near the rockies and helps drive this deeper. I just wouldn't bet that way right now since it hasn't been happening in this pattern.
