Mammoth Mountain & Eastern Sierra Weather Forecast

Footloose Sports Mammoth Lakes (Sponsor)Tuesday, June 29, 2021, @ 8:35 AM 

By Tuesday afternoon there will be a 60% chance of Thunder Storms in all areas of the Eastern Sierra.

Chances of Thunder Storms continue into the evening hours Tuesday with possible scattered showers early on Wednesday morning. By Wednesday afternoon there will once again be a 50% chance of more scattered T Storms.

If we still have residual cloud cover leftover from Tuesday on Wednesday morning that will limit how extensive the Thunder Storms will be on Wednesday during the afternoon and evening hours.

For those of you who are going to be in the back county or out for day use be prepared for some possible big thunderstorms with strong outflow winds, heavy rain, hail, and of course tons of thunder and lightning on Tuesday and Wednesday.

Looking out to Thursday into the July 4th Weekend you can expect to see more chances of Thunder Storms each day.

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.

Ted Schlaepfer – Mammoth WeatherGuy – The Powder Forecast – Posted Tuesday and Fridays at 5 PM November into Mid May. These forecasts are now responsible for many people getting multiple powder days on Mammoth Mountain over the years.  

Ted’s Bio: Ted has been a full-time Meteorologist (CCM) for the past 25+ years. He has always been fascinated with the weather,” skiing was just a natural extension of my love for snow and rain. I started skiing at age 5,  first discovered Mammoth in 1979 as a youth, and have been a regular visitor since the late ’80s.”.
