I get it but is has snowed in recent winters with marginal airmasses. We still need some semblance of a favorable look to our north in those cases to encourage a good track, along with a decently strong low. March 2018 is an example- good setup, decent cold in place. The winter of 20-21 (where the the temp never got below 20), the few light to moderate events here that were snow featured temps right around freezing or slightly above, but the synoptic setup was pretty good, and at least one of those was quite dynamic with banding and heavy snow that cooled the marginal surface. In this case the actual cold air/thermal boundary is still to our west/northwest and there isn't a reliable mechanism for confluence up top to get a meaningful high in a good spot for CAD. Transient lows moving through the 50-50 space in a progressive flow regime are just a crapshoot. So we mostly get ridging out in front with a weak high sliding off. That has rarely worked(here) without an antecedent Arctic airmass.
