Well, we're deviating from a pure and theoretical discussion of all things golf architecture now (important things like, you know, who could light a cigar faster - Willie Watson or Max Behr?), but yes, it did snow down to around 350' elevation on Monday morning with even a few wet flakes here on the floor of our little east bay valley. It was a very beautiful but cold (to my California blood) day.
I am not sure if it was quite cold enough on the bay side for your Stonebrae course to have gotten any snow or not. (obligatory golf course reference)
