Observations of Major Winter Storms and Interesting Weather Phenomena

September 8-10 Winter Storm in Southern Colorado - An unusually early winter storm delivers thundersnow, snow in my yard, and more than a foot of snow in the San Juan Mountains and other locations in Colorado. The thundersnow at Wolf Creek Ski Area and the snow in my yard were the earliest I have ever seen, and I got my first-ever capture with a lightning trigger of a lightning bolt associated with winter precipitation. Includes photos, video, and discussion of the weather setup and my observations over the three days that the storm affected southern Colorado.
