Mammoth Mountain Weather Forecast & Discussion

February 23rd, 2023 @ 4:45 PM – The first of two large weather systems will bear down on the Eastern Sierra late tonight. The snow showers by 4 AM should turn to moderate to heavy snowfall above 8000 feet.

Both these systems will feature very low snow levels with accumulating snow possible all the way down to Coso Junction on HWY 395. Travel is discouraged on Friday and Saturday with the low snow levels and the 8-12 inches of snowfall that is expected in Owens Valley.

For Mammoth Mountain, overnight snowfall amounts look to be in the 6-12 inch range from 8000 feet up to the top. On Friday into Friday night, the heaviest snowfall will be in the area with 2-3 feet of lighter powder snow possible.

More snow is in the forecast for Saturday with 6-12 inches now on the table. There will be a nice break on Sunday and then the next potent system will bear down on the area with an additional 3-5 feet of snow possible out on Mammoth Mountain.

If you’re going to be out on the hill on Friday, expect the snowfall to be moderate to heavy at times. Temperatures will be in the single digits to start the day with upper teens to low 20s by noon.  The wind forecast calls for a southwest wind of 25 to 35 mph, with gusts as high as 50-60 mph possible over higher elevations.

For Saturday, the snowfall will be moderate to heavy at times. Temperatures will be in the mid-teens to start the day with low to mid-20s by noon. Winds look to be in the moderate range.

By Sunday expect temperatures in the single digits to start the day with upper teens to low 20s by noon. SW winds should be on the increase ahead of the second upper-level low heading our way.

On Monday snow will be increasing to moderate to heavy at times lasting right into early Wednesday morning next week.
