Mammoth Mountain & Eastern Sierra Recreational Weather Forecast
Monday, October 11th, 2021 @ 1:24 PM
Weather Summary: Over the next several days the weather will be dominated by a strong cut-off low dropping into the great basin. Inside sliders are typical for this time of year, this one is on the strong side and will be extra cold and offer up a ton of wind and a bit of snow.
This pattern will drop temperatures in the Eastern Sierra that will be more winter than early Fall-like. Along with the cold, there could be 1-6 inches of fresh powdery snow that falls above the 7500-foot level. Areas below that could see a dusting to an inch of what white stuff.
The low will take its time moving east and will put us in a cold winter temperature pattern for several days this week.
If the Mountain wants to make snow it looks like there is a couple of day window to do it. Might be too early for snowmaking, but maybe not.
Checking the window cast there is moderate snowfall at 1 PM on Mammoth Mountain with 1-2 inches of new snowfall so far today.
