Mammoth Mountain Weather Forecast & Discussion

February 15th, 2024 @ 9 AMGood morning; the first system in a series of storms has made its way through the area with 6-12+ inches of new snow on the ground from Canyon Lodge up to the top of the Mountain. Winds and clouds will decrease later this morning, allowing more lifts and runs to open.

The next weak system moves through later on Saturday into Saturday Night. The third and what looks to be the strongest in the series hits Sunday night into Tuesday. QPF for that last system looks to be in the 2-3 inches range with 20-30+ inches of new snow possible.

The longer range outlooks keeps the off and snowfall going right through this month, with March also starting to look to begin with some snow. Currently, the Mountain has picked up 99 inches of snowfall this month at the 9000-foot snow study site, so it’s looking like well over 100 inches for February; let’s hope there will be a repeat of those totals in March.

If you’re heading out to the hill today, look for snow showers with mid-day temperatures in the upper 20s around the Main Lodge and lower 30s down at Canyon and Eagle Lodges. I’m not expecting more than a dusting to an inch of fresh this morning.

Friday looks great with pt cloudy skies and light winds out of the SW at 10-15 mph at times. Temperatures by mid-day look to climb into the upper 20s to lower 30s with mid-30s down at Canyon and Eagle Lodges.

For those coming up this weekend, expect light snowfall on Saturday with a bit of a break from the snow but not the wind on Sunday; by Presidents Day, you can expect moderate to heavy snowfall will be possible again.

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 MammothSnowman.com 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.
