Hmmm. I have done a lot of winter camping (and in snow, subzero conditions), and I'm going to say "reading an article about winter camping" is not sufficient to prepare you for actual winter camping.
I'd put this in the category of "go with people who have winter camped before" and/or "take a class on winter camping", at least in the case of snow and/or (worse) cold weather with possibility of rain. I have done this a LOT and avoiding hypothermia and dangerous conditions is substantially harder in winter vs. other seasons.
