Snow on Bay Area Mountains

This morning Silicon Valley woke up to snowcapped mountains. That's quite a rare event, it happens only a few times a year. We got one of our main storms overnight and the temperature has been close to freezing. I heard one report that snow was coming down in the East Bay this morning and the drive across the Sunol Grade, which connects the East Bay with the Silicon Valley, was akin to a drive in the Sierra Nevada.
