A Short-eared Owl banking in flight from last winter’s Owl Workshops. While I love cloudy, bright conditions for bird photography, there was no shortage of white sky days last winter. Lake Ontario never froze, which meant a lot of lake effect clouds and light snow.
Lake Effect clouds and snow occur when cold air moves across the open waters of the Great Lakes. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere. As the air rises, clouds form and grow into a narrow band that can produce snow, which can be heavy at times.
