White Christmas
Will Winchester, CA have a white Christmas?
Winchester, California had snow on the ground on Christmas morning in 4 of the 26 Christmases measured from 1996 to 2025. The last white Christmas there was in 2016.
Measured at Idyllwild Fire Dept, 22 miles east of Winchester. That station is far enough from Winchester, or high or low enough, that this is its own record rather than a call for the town. A white Christmas is an inch or more of snow on the ground at the Christmas morning reading, the line NOAA uses, counted from the station's own daily record.
