The Sierra snow pack is influenced by the phase of the PDO and the current El Nino or La Nina condition. That means it is highly variable as the chart shows. We are now in a cool phase PDO with a neutral position on the El Nino or La Nina condition. It should be an interesting winter in the Sierra.

Ran into this rather interesting record of snow in California. Runs from 1879 to 2011. What makes it interesting? There’s a wide range to it. There is some evidence for a bit of a cycle, but there is no long term trend I can see. (You can click on it for a much larger version that’s easier to read).
