Mammoth Mountain & Eastern Sierra Weather Forecast

Mammoth Mountain & Eastern Sierra Weather Forecast

Today’s Weather Story and The 10 Day Outlook​

Saturday 10-2-21 @ 3:32 PM We are currently under a ridge of high pressure in the Eastern Sierra. That’s bringing some of the last warm days of the early Fall into Tuesday.

Beyond that time frame starting Wednesday we will start to see some clouds move in temperatures drop and winds will pick up a bit out of the SW.

All this change is from a low that is forecast to drop down off the west coast of California.

The low looks to have some spitting taking place mid-week on both the EPS and GEFS models below. That splitting will slow the start of any possible rain or snow for Tuesday and Wednesday that we talked about a couple of days ago.

As of now, it looks like Thursday into Friday we could start to see some light rain and snow in the higher elevations with a slight chance of rain showers in the lower elevations. Snow Levels will be around 9000 feet to start all this fun late Thursday.

Over next weekend the question is if the low has cut off what track will it really take. Today’s version has it tapping a bit of moisture Saturday / Sunday possibly, that could add up to a couple of inches of wet snow next weekend if this outlook holds out.

This will be a fun week to be watching and reporting on the weather. We have been watching this possible change for over a week. Let’s pray it all comes thru, the forests could use a nice drink of freshwater. 🙂

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 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.
