Snow varies greatly from year to year. I'm out in Eldorado (about 10 miles outside of the City), which tends to get a bit more.
This year we got a total of a few feet, but no more than six inches at a time (which will melt within 24 hours, much less if it's a sunny day). That was a slightly wetter than normal winter.
Last year we had a total of few inches all winter. That was a somewhat drier than normal winter.
2006 we had one massive storm that dropped almost three feet in 24 hours. The City is not used to that and it took days to dig out. That is a very unusual storm though.
It really varies year to year, but we generally have four seasons, but all of them are typically mild.
