MAMMOTH THANKSGIVING

La Nina winters like this one, characterized by cold water bunched up off the coast of Peru, are tricksters. They can be either cold and wet or cold and dry. They can come late and end early or arrive early and end late. Often they portend the formation of a blocking ridge of high pressure that forces systems north through Oregon, Washington and Canada. Or not.

A series of increasingly cold storms began Friday the 19th, and by Thursday the Mountain had recorded 7 feet. For the first Thanksgiving in 6 years all the lifts were operating.

We can rule out late. Now the weatherman thinks winter might end early.
