I think he is such trying to present all of the data in order to refute the notion that he's biased. It's up in the air (no pun intended) with the ultimate impact will be.
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.
