What happened

The episode as NWS REV wrote it up.

Periods of mountain snow with a valley rain and snow mix will continued through the holiday weekend with this second of two impactful late season storms. This system brought travel regional impacts especially over Sierra mountain passes. The low pressure system that rotated cyclonically just off-shore the central CA coast enabled a south-southwest upper flow to tap into a thick layer of Pacific moisture that spread north and northeast into the Sierra and western NV.
