Areas downwind of Lake Superior, including Duluth, Two Harbors, Grand Marais, Houghton, Marquette, and Munising, receive heavy snowfall due to the lake effect, influenced by cold air picking up moisture from the lake.
The areas that would receive snowfall because of the lake effect are:
Duluth and the surrounding area, which is located on the North Shore of Lake Superior.
Two Harbors, which is also located on the North Shore of Lake Superior, to the east of Duluth.
Grand Marais, which is located on the North Shore of Lake Superior, to the east of Two Harbors.
Houghton, which is located on the Keweenaw Peninsula in the Upper Peninsula of Michigan.
Marquette, which is also located on the Keweenaw Peninsula in the Upper Peninsula of Michigan.
Munising, which is located on the eastern shore of the Upper Peninsula of Michigan.
These areas are all located downwind of large bodies of open water, which means that they are in the path of cold air that picks up moisture as it travels over the water. This moisture is then released as snow when the air rises over the land.
The amount of snowfall that these areas receive can vary depending on the temperature of the water, the wind speed, and the direction of the wind. However, they are all known for receiving some of the heaviest snowfall in the United States.
