Weather Summary

Cloud Cover:
Mostly Cloudy

Colder morning this morning with a chill wind the higher you went in elevation.  Interesting variations in wind speed were noted using the sensors at Mammoth Mountain.  mammothmountain.westernweathergroup.com This may have been due to the exact wind direction and blocking features of terrain.  Cloud cover was in and out with flurries of snow at times before I left the field at 4 PM.

Winds have been shifting around leading to interesting loading patterns.  Westerly winds led to additional loading in this area resulting in a larger slab than previous ones in this area.
