Mammoth Mountain & Eastern Sierra Weather Forecast

Recreational Weather Report for Mammoth Mountain & the Eastern Sierra

2-14-22 at 8:11 AM

Weather Forecast Overview: An inside slider weather system will bring an end to the early spring weather late today. This system will bring in some snow showers tonight into early Tuesday with 1-3 inches of fresh snow possible on most of the models. The HRRR model has a bit more snowfall than the other models at this time, see the image below.

If you’re going to be out on the hill today expect gusty SW winds with increasing clouds during the day. Winds will be 15-20 MPH around the Main Lodge with winds up top in the 30-40 MPH range with gusts to 60+ MPH possible.

Lower elevations will have mostly calm winds with highs in the 50s for Mammoth Lakes, with 40s in Crowley, and into the 60s for Bishop.

Wednesday into Sunday – Ridging will start to build back into the area as the slider system moves off to the east. Expect fewer winds with warming highs into the 40s for Mammoth Mountain. Lower elevations such as Bishop will be into the 60s.

In the image below you can see the HRRR model has a bit more snow than the other models are bringing in over the next 24-36 hours.

The EPS has 1-2 inches of snow for Mammoth Mountain from this first inside slider system. There is a second slider next Monday that will bring more snowfall as you can see on the gif image below.

Below is the EPS model over the next 10 days. You can see the inside slider for today into Tuesday, then that system gets replaced by more ridging and then a repeat with a second inside slider next Monday / Tuesday. The problem with an inside slider is the system has no moisture to work with so instead of feet of snow Mammoth Mountain gets inches.

March Miracle: Everyone is starting to hope for a decent March of snowfall. The GEFS has several feet of snow for the area and has shown that solution for days and days now.

The EU is still much drier so unfortunately there is no consensus on what March will bring. One thing is for sure we need a March Miracle of Snowfall to boast the snowpack and bring more water for the upcoming spring and summer seasons.

Spring Outlook: Post La Niña Winter Springs can be cool with snow showers at times. The cooler weather helps to extend the ski season until at least Memorial Day during a low snow year. I have only seen Mammoth Mountain miss Memorial Day once due to a lack of snow in the last 40 years.

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.
