Mammoth Mountain Weather Forecast & Discussion
December, 26th 2022 @ 4:02 PM – The Mango connection is on the way and ahead of it, temperatures have warmed up big time on Mammoth Mountain just as was forecasted. When I left little eagle at noon the car gauge was at 48 degrees.
What you can expect over the next 48 hours in Mammoth will be a wet wild ride. Mid Latitude storms are warm and this first system of several on the way will have some very high snow levels by Tuesday morning.
The action should start late this evening with snowfall all the way down to 7500 feet. Sometime after midnight, the snow line is forecast to be up above 9000 feet. By Tuesday snow levels jump up to around the 9600-foot level before falling to Canyon Lodge by late in the day. Tuesday night snow levels are expected down to around 7000 feet. Winds will be gusting 35 to 45 mph with gusts up to 90 mph along the ridges.
As of now, this first system looks to bring around 20-30 inches of snow to the mid and upper mountain sections of Mammoth Mountain. The rain we get at the start should be absorbed by the current snow pack and not cause any damage.
The snow that does fall is going to be heavy and wet snow don’t expect any light and dry Alta powder from this system or any of the upcoming systems in the next 6-10 days.
Beyond the next 48 hours, there will be a short break later Wednesday into early Thursday before the next wave of heavy wet snow moves into the area. That second wave of snow looks to be in the area into early Sunday.
It does appear that more snow will be possible in the 6-10 day fantasy outlook period with a break looking likely beyond day 10.
