Right I know 10:1 is just an average, but here we've had everything from 5:1 to 20:1. Our big noreasters are around 11:1-12:1 typically.
My point wasn't about the ratio of snow to liquid, but the fact that there's much more variability with snowfall because of the ratio-- whether it's 5:1, 10:1 or something else. A small difference in rainfall is equivalent to a much larger difference in snowfall.
