Based on this cycle, I predict the following years will be wetter than average in the Sierra: 2018, 2024, 2032, 2038, 2045. I predict the following years will be drier than average: 2019-2020, 2025, 2029-2031, 2043-2044. If 2024 turns out to be wet, I'll write up my methodology :). Check back in 7 years!
