Op runs flip flop around- its just the nature of deterministic guidance 4+ days out. Check out the 18z ens mean. Low 40s with SW flow ahead of a major cold front is exactly what is expected in mid winter. The "good" period(we hope) begins just beyond this.
Looks alike a healthy cold front approaching at the end with some snow associated with a wave along it. Sure its a bit warmish out in front as it always is in these cases, but nothing 'good' was expected until just beyond this time.
