Mammoth Mountain & Eastern Sierra Weather Forecast

Mammoth Mountain & Eastern Sierra Weather Forecast

Footloose Sports Mammoth Lakes (Sponsor)Sunday, June 27, 2021, @ 8 AM There are a few clouds around the area today. Expect a few build-ups but do not expect any Thunder Storms.

This week’s weather story starts will start with some hot temperatures and then we cool a bit and get into a monsoon flow.

We got lucky here in the Eastern Sierra as Washington and Canada are getting hammered with heat from a very strong ridge of high pressure.  Had that ridge of high pressure been located over California we could have seen all-time record highs broken in the Eastern Sierra.

Now that we dodged that heatwave all eyes turn toward the monsoonal flow headed our way. By Monday there will be a 40% chance of Thunder Storms in the High Country and a 20% chance for the lower elevations.

With the increased chance of thunderstorms You can expect dew points to be coming up this week, it will feel a bit muggy in our very dry environment.

Moisture looks to increase a bit each day with Wednesday into Friday looking to be the best chance for moderate to heavy rain.

As is always the case with thunders storms, not all areas will be getting really wet, just the higher terrain and a few locations that get caught under one of these storms that happen to roll into the lower elevations.

If your 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.  It’s best to go indoors or take cover when you hear thunder. Always have a plan and take action sooner than later. 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.”.
