Area Forecast Discussion

Owens Valley / Mammoth Lakes / Mono County / Death Valley

Dennis Mattinson / Sierra Atmospheric Forecaster

Synopsis – MON SEP 15 2025

High pressure ridge will build over CA / NV. As such, expect dry conditions, lighter breezes and warmer temps. Your temps will warm up to ~92° by Wednesday in Bishop. But on Thursday our big ridge gets pushed East over 4-corners from a trough moving thru the PACNW. So we get chances of T-storms into the weekend. DMATT
