Mammoth Weather Forecast and Synopsis for Monday, August 9th, 2021 @ 11:46 AM

Weather Synopsis: This week’s weather story is starting with warm temperatures, dry conditions, and very hazy skies.

As the wind starts to shift out of the south to the southeast on Tuesday the haze and smoke should start to move out of the area.

With the changing wind flow, there will be some moisture working into the area offering up a chance of thunderstorms once again. There could be a few build-ups and a stray thunderstorm or two on Tuesday with increased chances on Wedensday.

This outbreak of storms is not looking anywhere near as wet as the last cycle we went thru. As of now, it’s questionable that it last past this Thursday.

Temperatures: Highs over the next week will be in the mid-70s on Mammoth Mountain and up in the Mammoth Lakes Basin at the 9000-foot level. Mammoth Lakes will be in the low 80s with Bishop into the upper 90s to low 100s.

Smoke and Haze: More than likely the Eastern Sierra is going to see waves of haze and smoke at times until at least mid Fall.

Here are the links to the local NWS Forecasts for Main Lodge & the Mammoth Lakes Basin, Mammoth Lakes, June Lake, Crowley Lake, and Bishop.

Extended Outlook: Looking out the next 16 days into your fantasy forecast after this week’s high-pressure doom retreats we could possibly see some troughing off the California Coast. That would bring dry but much cooler weather than we have seen for the last 2 months.

Looking out towards Fall and into the Winter months, it’s looking dry and warm to start. Models have moved from a neutral winter to forecasting a la Nina to set up again.

Kind of early to jump on how strong it could be. Mammoth and the central Sierra have done good with weak La Nina’s, not so bad with moderate ones but if it’s strong again expect a drier year.

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.
