Area Forecast Discussion

Owens Valley / Mammoth Lakes / Mono County / Death Valley

Dennis Mattinson / Sierra Atmospheric Forecaster

Synopsis – MON SEP 22 2025

Our overall weather pattern shows a cut off low off the SOCAL coast and high pressure over NORCAL / PACNW. So for the next few days warm conditions will exist from that high pressure. By mid week, that aforementioned cut off low will drift inland, over Southern NV. This will bring on chances of showers and t-storms (20 – 30%) particularly over higher terrain, with your temps running near average.
