Area Forecast DiscussionOwens Valley / Mammoth Lakes / Mono County / Death ValleyDennis Mattinson / Sierra Atmospheric ForecasterSynopsis – TUE SEP 23 2025High pressure will bring on mostly sunny skies and temps a bit above normal. But by mid week, a cut off low off the CA coast shifts inland, as current high pressure moves into the N. Rockies. This will bring some moisture into our area and give us chances of showers and t-storms. Precipitation chances look to run some 30 – 40%, particularly over higher terrain, Wednesday and Thursday. -DMATTArea Wide Temperatures Today:Bishop: 88 / 50Big Pine: 86 / 56Independence: 87 / 61Lone Pine: 86 / 63Olancha: 89 / 66Mammoth Lakes: 69 / 45Death Valley: 109 / 83Related
