Mammoth Mountain & Eastern Sierra Weather Forecast
Mammoth Weather Update for Thursday, July 22nd, 2021
Synopsis: Dry weather with just a few clouds and slightly above normal highs will be in store for us into Saturday.
By Sunday the SE flow returns and we will see more isolated thunderstorms.
Thunderstorms become more the norm next week. If you’re planing on being in the backcountry or out for a day hike or ride be prepared.
Winds: over the next few days you can expect afternoon and evening winds from the SW at 10-15 MPH with gusts over the higher elevations 25+ MPH during the PM hours.
Smoke and haze: I would expect just light amounts at times until further notice.
Extended Outlook: Looking out over the next 16 days I am not seeing any excessive heat waves. Snowman

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.
