Dennis Mattinson’s Weather Forecast for Monday and Tuesday

Rain? Sounds “doggone” good to me!

WEATHER: The Owens Valley / The Town of Mammoth Lakes 

TUE MAR 02 2021 4:18 AM PST

SYNOPSIS: A quick moving closed low will shift a weak EPAC ridge axis East, with increased cloud cover and a slight chance of showers in Mammoth late Wednesday into Thursday. Mammoth looks to get maybe an inch or two on the Mountain and the peaks around June Lake, 1 – 3 inches. That system wobbles east, dropping a little snow over the San Juan Mountains of Colorado. High pressure then returns late Thursday, bringing a spell of mild and dry weather through Friday. There are signs of a pattern change this weekend, as high pressure gets bumped by a developing EPAC low. Unsettled weather looks likely heading into next week. Stay tuned as I iron out the details…DMATT
