The increasing instability of Fall this year first brought us a couple of, "dribbles," of Fronts coming across the Sierra on September 14 (calendar). This has been followed by a series of weak fronts, seven in total so far, that have come from both the North and South.

Winter to Spring to Summer 2015-16: Depths of Drought to Depths of Flooding?

December 11 2015

Our goal here is to track each stage of the Fall-Winter-Spring transition to Summer conditions. Our main goal is to determine when trails will open to Summer conditions.

As Fall comes to a close certain patterns have manifested themselves. These have set the stage for the advent of Winter. We've seen that the remnants, the tail ends of the tropical fronts hitting the Sierra have put a reasonable Fall coat of snow on the Sierra.
