The worst Blizzard in Buffalo's (WNY) history happened in 1977. It lasted 25 hours and killed 29 people. For those that are interested it really is a good read. http://en.wikipedia.org/wiki/Great_Lakes_Blizzard_of_1977 and a slide show http://www.youtube.com/watch?v=m-gRb_MuUgg . The only blizzard declared a natural and national disaster by the American and Canadian governments.
