It isn't looking good if you are wanting a White Christmas for this year. Long range models slide a small system through early next week, but it will take too much of a northern track to bring us snow.
Perhaps some of you might have a White Christmas if temperatures manage to stay below freezing the remainder of the next week. This would be in locations that already have snow on the ground.
The National Climatic Data Center defines a "White Christmas" as having "a snow depth of at least 1" observed on December 1".
