I mentioned this a few days ago. The n stream flow was modeled to be more sharp and with more digging, for both this past system and probably next week. We ended up with, and will likely end up with models showing a more climatologically favored setup, a little more relaxed and rounded. This should allow the southern stream to press north of what models show from D5 esp. the gfs and Canadian, which imo tend to be cold biased at that range.
