Synopsis – MON OCT 20 2025

High pressure takes hold of our region today, bringing dry and mild weather thru much of this week. The only fly in the ointment is Wednesday, where low pressure sneaks into Mono County and parts of Inyo County for a 20% – 40% chance of showers. Dry weather then returns Thursday and mostly Friday before another, possible larger system moves into our area. This system could affect Inyo County as well. Stay tuned for updates…DMATT
