Owens Valley / Mammoth Lakes / Mono County / Death Valley

Dennis Mattinson / Sierra Atmospheric Forecaster

Synopsis – MON DEC 08 2025

A growing ridge of high pressure (which has stalled over the EPAC and Western US) will increase temps to well above normal this week. So by Wednesday, Bishop is looking at 72 degrees (18 degress above normal) and Death Valley will see 82 degrees. These temps are highly unusual for this time of year. Right now any pattern change is out in fantasyland (mid December or beyond)…DMATT
