Dennis Mattinson / Sierra Atmospheric Forecaster

Synopsis – MON MAY 12 2025

After above normal temps Saturday. Our upper level ridge will be replaced by a deep low moving into NORCAL Sunday. By Monday / Tuesday light precipitation is expected in Mammoth, but not in the Owens Valley, as the air mass is too dry that far South. Also, expect breezy to windy conditions thru Monday (G 45 mph). Temps will decrease significantly with the cold front on Tuesday, with a 10 – 15 degree drop. The rest of the work week looks warmer, as high pressure moves in…DMATT
