There’s probably two ways of looking at it.
1) What’s your favorite in terms of the end result (for me it was Snowmageddon part 1, hands down). This was the question I was asking in the poll.
2) Which one was the most impressive/anomalous in terms of the meteorology? That one’s above my pay grade, but perhaps Dec. 2009 because of the time of year, or March 1993 because of the overall setup? PDI seems insane too from what I’ve read.
