Mammoth Mountain Weather Forecast & Discussion

Saturday, March 25th, 2023 @ 7:30 AM – Good morning expect mostly clear skies today and Sunday with some afternoon clouds with a few snowflakes possible.

The next winter storm coming into the Mammoth Mountain and Eastern Sierra areas is scheduled for Tuesday with moderate to heavy snow expected during the day and into the overnight hours.

Snow showers and cloudy skies with gusty winds will then be the rule on Wednesday and Thursday before skies clear out next Friday. This next system has some uncertainty to it at this time.

Snowfall amounts for the next weather event, as of this Saturday morning, look to be in the 6-12 inch range for the 7500 to 8500 range with 1-2+ feet possible over the higher elevations. In the best-case scenario, the Powder Fields of Mammoth Mountain could see 2-3 feet of snowfall.

Never had to say this before but let’s hope for the lower-end totals to pan out as Mammoth Mountain and the Eastern Sierra have more than enough snow at this point.

This is the most snow I have personally ever seen since my first full season out on the hill in 1985. It’s really strange having to ski down to load on all the chair lifts.

3-25-23 @ 7:47 AM – 10 Day and Longer Range Fantasy Outlook

After the Tuesday/ Thursday weather system comes thru there area skies will return to mostly clear with dry conditions expected next Friday – Sunday. Early the following week, an inside slider will be moving into the area with much cooler air and a chance of a dusting to several inches of snow.

Out past day 10 models are going to be a bit more unreliable as it’s now spring time. Long ensemble models overall want to keep troughing in the west with weak to moderate storms possible at times.

The GFS and the ECM weeklies however still show decent footage of snow over the next 2 weeks. If those models are right the seasonal snowfall total would go over the 700 inch mark for the season.
