One of my all time favorites was the 12/1/06 storm. It wasn't too crazy as far as snow totals here (11"), but we just narrowly escaped getting completely shut out by the northwest edge of the precip. The wall of snow backed in from the southeast and stalled about 20-30 miles northwest of here, and on the other side of that they didn't get a flake. When the snow moved in it went from nothing to heavy snow in 10-15 minutes, and the winds picked up as it started to precipitate as well. Models had been showing us right on the extreme cutoff so it was difficult to forecast and figure out how much would fall. IIRC the official forecast from DVN had us in like 3-6" or something. Just southeast of here in Princeton they had 18".
