Mammoth Mountain Recreational Weather & Travel Forecast

4-7-2024 @  9:25 AM – Good morning; the roller coaster of Mammoth spring weather is upon us now.

The low that moved through and dropped 2-3 feet of new snow on Mammoth Mountain has moved well off to the east. The next low (a hybrid inside slider) will move through the area over the next 24 hours.

This system will have little to no moisture to work with, there could be a few clouds with some scattered snow showers later today into the nighttime hours, but that is about it.

As the low drops to our SE early Monday, it will kick up some moderate NE winds through Tuesday. By Wednesday, a quick-moving ridge of high pressure will move through the area, kicking up mid-day temperatures by 8-12 degrees into Thursday.

Models predict a weak to moderate low by next Friday and Saturday. Our trusted EPS Ensemble model has the strongest outcome right now, with 8-12+ inches of snow showing up. As of this Sunday morning, other models are weaker in their solutions for snowfall.

Way out in the 8-10 and 10-15 Day Fantasy Outlook periods, the next ridge of High Pressure looks to move in and be locked in place for a week or more. Since it’s Spring, don’t be surprised if a weak to moderate low sneaks into the forecast period as we move closer to that time frame.

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.
