Area Forecast Discussion

Owens Valley / Mammoth Lakes / Mono County / Death Valley

Dennis Mattinson / Sierra Atmospheric Forecaster

Synopsis – MON SEP 01 2025

Warming and drying continues thru at least today, with areas of smoke and haze. This should bring on a mostly pleasant Labor Day. All due to high pressure strengthening over Utah and Wyoming. Then Tuesday, the ridge will shift slightly Eastward allowing moisture from a shortwave off the coast to move into Eastern NV. That puts the Eastern Sierra on the fringe of that moisture most of this week. Expect slight chances of t-storms thru at least Wednesday…DMATT
