Basically you want seasons instead of monotony.
So the question is, if you want snow some times, do you want to live in the snow, or have access to the snow, and how close is close enough? The bay area has Tahoe, which you can reach in about 4 hours, for access to snow. If you want to actually live in the snow for at least part of the year, the SF Bay Area won't cut it then.
Though it can lead to ice and things like the Atlanta snowpacalypse.
