Area Forecast Discussion

Owens Valley / Mammoth Lakes / Mono County / Death Valley

Dennis Mattinson / Sierra Atmospheric Forecaster

Synopsis – MON DEC 22 2025

While Mammoth gets chances of rain / snow today, partly sunny skies are in order for the Owens Valley. By Tuesday, expect a significant change in the weather, as a deep Pacific trough off the coast allows colder storms to move through the area. Overall then expect an active week, with mountain snow and valley rain, enhanced winds, and travel impacts thru Christmas day into Saturday. More updates to follow…DMATT
