Mammoth Mountain Weather Forecast & Discussion
3-19-2025 Mammoth Weather Summary: Breezy conditions will be in the area over the next 24 hours. After that, the area is lined up to see a couple short wave high presure ridges move through. The second one for Sunday into next Wednesday looks to be strong and will give Mammoth Mountain and the Eastern Sierra a real taste of spring.
Beyond that time frame winter looks to return as a long wave trough sets up off the west coast for more powder days in the high country and some rain showers in the low lands down to Bishop. Winter to Spring and back to Winter again, Yahoo!

Mammoth to Bishop Weather Discusion: Friday is the first full day of spring and the area will be under a short wave ridge of high presure that willb e repclaed by a second much storng ridge that will effect the area Sunday into next Wednesday. This ridge will really kick up temperatures turning the snow packer over to spring possibly all the way to the Sierre Crest during the peak of the ridge early next week.
The good news for those of you who want more winter and powder days is there is a change back to winter on the models starting on day 8. By Aprils Fools day the ECMWF has one of the larger April system I have seen on the models in a while. Since it’s so far out and it’s srping and on April fools day we won’t by into the 5-6 inches of water the ECMWF had on it last night. The Ensembles have much less snow but enought to cover the spring snow and bring back winter.
