Around here, after all these years, I finally noticed how they figure how many inches of snow to forecast for. Whatever they call for I just cut it in half and I'm usually closer to correct than they are. Example - They call for 4 to 6 inches of snow........ So I figure we're gonna get 2 to 3 inches; and that's what it usually turns out to be. Then, recently I realized that if we get more than predicted; lots of people get angry and bitch about it; but if we get less there's no complaints. So they routinely over estimate those things as a C.Y.A. move.
