The NAO block could completely break down, and we could still get a decent event(s) in Feb...hell, I remember we stole a mod event in Feb 2018, while I was in Uganda. Look at Feb 2006...
Just a cautionary note...I would not be issuing kudos to anyone, right now, just as I was puzzled why some where high-fiving the Jan 2011 vibe back near New Year....the tenor of the season changes so fast. There remains a path to a season altering event as we near peak climo.
I predicted blocking (often east-based) from Dec into a portion of January, and slightly below avg snowfall....blocking will likely persist a bit longer than I had thought, though.
