Synopsis – MON JUN 23 2025

Pre and post frontal winds peak late today, leading to slightly lighter winds and below normal temperatures on Sunday thru Tuesday. All of this due to an associated trough which dropped through the Great Basin over the weekend. Also Monday and Tuesday Mammoth has a slight chance of showers. After Tuesday, expect temps to raise back up again to the above normal range to the moderate HeatRisk level…DMATT
