Ended up right at average climo, which puts it above the median, arguing for a B or B-. But only two "sled-able" events and the lack of snowcover argue for a C. I'll join the chorus at a C+.
By the way, this pretty much kills off any argument that people have of whether they want to get to climo with a variety of smaller and medium events or one blockbuster. Give me a 20" bomb and nothing else over this winter.
