My understanding is that blizzards are characterized by white-out conditions, that is, you cannot see for any appreciable distance in front of you due to the combination of wind and snow. I cannot imagine it being safe to ski in such conditions, since it would be very easy to veer off course and run into a tree.
Now just a plain-old heavy snow storm? Sure, and freshly-falling natural snow is great for skiing. But I want to be able to see where I go!
I haven't personally experienced what I would call a blizzard, but the one that I always heard about growing up was the
blizzard of 1978. In Dayton, well south of lake-effect-snow area, there was over a foot of snow, wind chills of -60ºF (-51ºC) below zero, and gusts of wind gusts
averaging 50-70 miles per hour (70-110 kmph). The main east-west highway across the northern part of the state closed for two days, and the barometric pressure was the lowest ever recorded in the central U.S.
Right about in the middle of all that was Ohio's largest ski area. It's no Alp, but I agree with Valka - only someone with a death wish would have been going out skiing in those conditions.
Other than that, the only "blizzard" I remember hearing about is the 1950 one, famous for the "Snow Bowl" football game, where there were two inches of snow falling per hour, but the gusts were only up to 28 miles per hour. Sleddable? Probably on a familiar hill. Skiable? Maybe on a familiar slope, although those winds might be pushing it. Reports indicate that visibility was roughly 38 yards (35 meters), so you could still see where you were going if you were traveling slowly enough.
So it probably depends on whose definition of "blizzard" it is. If the Swiss considered it a blizzard, I'd personally be staying inside. weather.gov defines it thusly:
How does that impact the best area to live? Personally, I don't think I'd enjoy living in the parts of the U.S. where the snow doesn't melt till mid-April and "blizzards" (by stricter definitions, including white-outs) are common. Those areas are pretty rare - maybe the uppermost parts of New York (Watertown?), and the upper parts of the Rockies, and if you love skiing, maybe those long ski seasons make it worth it. But I understand why, for most people, those are vacation destinations.
