Dreaming of a white Christmas?

Singing: ''I'm dreaming of a white Christmas"

Now that you have that song in your head, let's discuss the probability of seeing a white Christmas.

climate.gov
This map is from the National Climatic Data Center showing historically the areas that have the highest probability of seeing a white Christmas.  Based on data going back to 1981, northern Illinois and southern Wisconsin have roughly a 60% to 70% chance of seeing an inch or more of snow on the ground.

Keep in mind that this map doesn't mean we'll have a 60% to 70% chance of seeing a white Christmas, but rather climatologically the probability of snow on December 25th, and should only be used as a guide.  Actual conditions this year could, and probably will, vary from these probabilities due to current weather patterns.  If you're dreaming of a white Christmas, I wouldn't lose hope just yet.  A changing weather pattern could bring some snow to the Midwest next week.  More on that can be find right here.
