I believe there is some sort of negative correlation between October and the winter, while there is a positive correlation between November and winter. But the October snow argument is a myth.
It's worth checking before you go through any editing trouble because believe it or not, there is actually symmetry between my concurrent analogs, and low ACE, high solar years.
Good job.
I like your analogs, but I'm not sure why you chose to disregard low ACE based on an increase in activity. We are still definitely low ACE.
I would also be careful about implying that this will be a bonafide moderate la nina because its struggling to even get there in terms of ONI.

It always was more about the rate of change....ie SAI, more then the actual cover (SCE). The people claiming its worthless are every bit as ridiculous as those claiming its gospel.
It's one damn tool.
