Mammoth Mountain & Eastern Sierra Recreational Weather Forecast
Tuesday, October 12th, 2021 @ 11 AM
Weather Summary: Over the next couple of days the weather will be dominated by a strong inside sliding low-pressure system that has brought more snow and great snowmaking conditions.
The low will take its time moving east and will keep the cold air around for several days. By the weekend a ridge of high pressure moves in and brings with it some great Indian summer weather to Mammoth Mountain and the High Country.
Nope, it will not be warm enough to melt off all the snow at the ski area. Crews are working hard to pack and preserve what’s fallen and the snow they are making right now.
Checking the window cast clear skies with very cold October tempratures as we approach the 11 AM hour.
Taking a look at local conditions the last couple of days. Yesterday at the top of Mammoth Mountain there was a high of 18, the low this morning was 6 and at 11 AM the temperature is 9. The peak wind gust over the last 24 hours was 101 MPH @ 11 PM out of the ENE.
The snow study site @9000 feet is showing 5 inches of snow on the ground with a temperature of 18 with .27 of precipitation on Monday and 4.2 inches of fresh snowfall. That brings the snowfall total this week up to 10.7 inches with more up top.
In Mammoth Lakes, the temperature peaked at 34 degrees on Monday with a low of 17 degrees this morning. Winds in town have been out of the ENE with peak gusts of 9 MPH today.

Then on Monday, there appears to have been 4-6 inches of new snow at the snow study site… trying to confirm the exact amounts from the last 24 hours with the ski patrol.

Who Are We?
Steve Taylor – Mammoth Snowman – Over the last 30+ years, Snowman has spent countless hours studying and learning about Mammoth Mountain Weather and Snow Conditions first hand. He has been skiing around the hill with marked ski poles since March of 1991 so he can measure the fresh snowfall amounts out on the hill.
Snowman started blogging this information back in 1990 on the old Mammoth BBS system, then the RSN Forums and then on to MammothSnowman.com in 2004 with Video & Photo Blog report. (No YouTube back then). Facebook got added to the fold back in 2008 and then the Facebook Group in 2016.
Reports, videos, and photos from the website have been featured on both local TV Stations here in Mammoth, along with AP, Fox, ABC, CBS, and NBC News.
