Mammoth Mountain Weather Forecast & Discussion

2-17-2024Two Storms are in the forecast at this time, the first is a smaller system coming in Saturday night that will offer up a few inches of fresh on Sunday for a low end powder day. 

By Sunday night through Tuesday, you can expect a massive dump of heavy wet base snow. On Tuesday night, snow levels will drop, leaving some nice powder on top of all that new base snow.

If you’re heading out to the hill this weekend, expect light snowfall at times on Saturday with mid-day temperatures in the lower to mid-30s with SW Winds at 15 to 25 MPH increasing during the afternoon hours with gusts of 45-65 mph expected on the mid and upper mountain later in the day. 

For Sunday, expect mostly sunny skies; mid-day temperatures will be in the lower to mid-30s.  The wind will be out of the southwest wind 20 to 25 mph, with gusts as high as 35-45+ mph. 

Snowfall amounts from Sunday night into Wednesday look to add up to 3-5 feet. Most of the model data I use has 2-3 feet with up to 4 feet over the top.

Author – Steve Taylor – The 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 reports. (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 and Bishop, along with KTLA, AP, Fox, ABC, CBS, and NBC News.
