It that time of year when we begin to look at the polar region to see the ice and snow cover expand. As the ice/snow cover expands, the polar icebox really gets going. The cold air can remain cold as it travels south into the lower 48. Hopefully, we'll see a lot of cold air this season. The map on the left is from September 3 and the map on the right is today, October 3. We'll check back in November to see how much further south the snow and ice has expanded.
