Mammoth Mountain Weather Forecast & Discussion

January 27th, 2024 @ 4 PM – The January thaw is on, with temperatures in the mid to upper 40s around the Main Lodge and lower 50s at Little Eagle this afternoon. Look for more of the same into Tuesday next week.

By Wednesday, the next possibly moderate storm system is showing up in the 7-day forecast. This one is a bit suspect at this time as far as how much snow it can deliver. As of this post, new snowfall amounts from Main Lodge to the Top will be in the 10-16 inch range by late next week.

The NBM has 1-2 feet of snowfall. Snowfall ratios look to be around 8-1 to start later Wednesday and then 10-1 during the main frontal passage, with some 12-1 snow or, better possibly, on the back end of the system.

Snow levels start around the 7000-7500-foot level later Wednesday in the evening hours. The snow levels will come down later Wednesday night into Thursday to around the 6000-6500 foot level and then down to around 4100 – 4600 feet on Friday.

Models are showing more snow behind this first system, but with the way this season is gone, it’s hard to buy into any outcome beyond 5 to 7 days. If the EU is right for the extended time frame, just beyond day 10, there could be some large snowfall totals.

If you’re out on the hill Sunday through Tuesday, skies look clear to cloudy at times, with mid-day temperatures in the lower to mid-40s around the Main Lodge and mid to upper 30s from MC Coy Station to the Top. Overnight lows will dip into the low to mid-30s

Winds will be light at 5 to 10 MPH out of the SE to East into early Monday and then shift to the SW late Monday afternoon. The wind speeds should start to pick up on Tuesday ahead of the snow chance of snow that moves into the area by Wednesday afternoon.

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.
