What is the snow effect in the Great Lakes?
What is the snow effect in the Great Lakes? Lake Effect snow occurs when cold air, often originating from Canada, 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.
Can lake-effect snow happen anywhere?
Anywhere! Lake effect snow can occur over any unfrozen body of water where the fetch is long enough to gather enough moisture to create snow. Lake effect snow can occur over Lake Tahoe, the Great Salt Lake, the finger lakes, and even has been reported over rivers in the Midwest!
Which Great Lake is most likely to freeze over?
Lake Erie averages the highest ice cover Of the five Great Lakes, Lake Erie typically reaches the highest annual maximum ice cover, often exceeding 80 percent.
