What drives Christmas snow in Portland?
A storm passing in the right position can deliver heavy snow; a small track shift can turn that into rain or mix.
Snow retention usually improves quickly away from the immediate coast and at higher terrain.

Does snow have to fall on Christmas Day in Portland?
No. A White Christmas means at least one inch of snow is on the ground on December 25. Snow can fall earlier and still count.

The estimate becomes more actionable as December progresses, especially when observed snowpack and the Christmas-week forecast are available.
