Mammoth Mountain & Eastern Sierra Weather Forecast

Mammoth Mountain & Eastern Sierra Weather Forecast

Footloose Sports Mammoth Lakes (Sponsor)Thursday, July 1, 2021, Good morning from the Mammoth Lakes area.

There have been some nice rain showers mixed in with the thunderstorms we have had the last couple of days.

Rainfall amounts were in the .25 to .50 of an inch range in the Mammoth Lakes area. Bishop picked up some rain at times the last couple of days but amounts were still just a trace.

For today there is a 50% chance of thunderstorms today in the high country, with a 30% chance for the lower elevations.

Chances of thunderstorms continue into Friday and the Independence Holiday weekend. However, there will not be as much action as we have had this week with chances this weekend at just 20%.

Expect more isolated storms with build-ups mainly over the higher terrain above 8000 feet. If you’re going to be heading out for a long hike the next few days I would still advise you to go early to avoid any thunderstorm action.

Daytime highs have come down this week and they look to remain in the mid to upper 70s at the 8000-foot level with mid to upper 90s in Bishop through July 4th and into early next week.

Nighttime lows have come down a bit with the mid-50s for the higher elevations will lows to mid-60s in the lower elevations.

Air quality remains good after a few hours of smoke on Wednesday from the #bluefire.

Beyond this weekend temperatures will be coming up as a new high-pressure system will be building into the area. That will be heatwave number 3 for the region in the last few weeks. 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.

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.”.
