Dennis Mattinson’s Weather Forecast for Friday, Saturday, and Sunday

WEATHER FORECAST AREA: The Owens Valley / The Town of Mammoth Lakes

FRI MAR 12 2021 4:10 AM PST 

SYNOPSIS: Our broad and cold (541 DM) cut off low will continue a slow grind into the Four Corners Region today. Moisture / instability wrapping around that low should produce a few on / off showers today as well. Brief ridging (with raising heights to 570 DM) moves in on Saturday and Sunday, giving us warming temperatures and what looks like a nice March weekend in Mammoth and the Owens Valley. However, a possible weak system might progress through the Great Basin early next week, for a slight chance of showers Sunday night into Monday. Right now, I have low confidence on the extent of precipitation in our area, so stay tuned to Monday’s forecast…DMATT

DMATTs Weather Fact: In the last few days, the Main lodge picked up 14 inches and the Summit 16 inches. And don’t forget to move your clocks forward 1 hour on Sunday.
