Lake Winnebago and Lake Michigan Lake Effect Showers

The water temperature of Lake Winnebago is around 70 degrees Fahrenheit, or 21 degrees Celsius, while temperatures at 5 thousand feet are around 3 degrees Celsius. This temperature difference causes unstable conditions that can result in shower development. While a mid level trough created conditions favorable for showers, the unstable air over the warm waters of both Lake Winnebago and Lake Michigan produced several bands of rain showers. While this is common over Lake Michigan, is more rare to occur from Lake Winnebago.
