While I'm ranting: "Normal" Snowfall ISN'T

I can't STAND this sort of shoddy misinformation:
So far this winter Milwaukee has notched 65.7 inches of snow. That's a wee bit over the normal of 33.9 inches.

THERE IS NO NORMAL. "Normal" precipitation as labeled by meterology forecasting companies is merely the average of a sliding 30-year period. So the "normal 33.9 inches" they speak of is the AVERAGE snowfall of years between 1971 and 2000. 5.5 feet very well could be statistically normal for Milwaukee. Yes, it's above an artificially-constrained average, but it's probably not statistically aberrant, especially if you include years before 1971.

Mostly I'm tired of people bitching about it, like they expect Wisconsin to be Alabama in February. It's still a free country for a few months, feel free to leave...
