Weather Trivia

The Greenstone region often sits in a prime corridor for Colorado lows tracking northeast. When these systems tap into moisture from the Great Lakes and cold Arctic air to the north, they can quickly turn into high-impact snow producers, particularly for communities inland from Lake Superior.
