Lake Effect Snow is a unique winter weather phenomenon that occurs when cold air moves across long expanses of warmer lake water, typically the Great Lakes in North America. Here's how it works:

1. The process begins when cold, dry air moves across a large, relatively warm body of water. The temperature difference between the water and the air should be at least 13°C (23°F).

2. As the cold air passes over the warmer lake, the bottom layer of air is heated and picks up water vapor from the lake through evaporation. This warm, moist air rises into the colder atmosphere above.

3. As this air rises, it cools and condenses, forming clouds. When the conditions are right, these clouds produce snow - often in narrow but intense bands.

The resulting snowfall can be extremely localized and intense. For example, one area might receive several feet of snow while a location just a few miles away gets nothing. This is particularly common in areas like:
- Buffalo, New York (affected by Lake Erie)
- Syracuse, New York (affected by Lake Ontario)
- Western Michigan (affected by Lake Michigan)

Lake effect snow typically occurs early in the winter season when the lakes are still relatively warm and haven't frozen over. The snowfall can be enhanced by local topography - as the snow bands move inland and encounter hills or higher elevations, the lifting effect can increase snowfall amounts.

Some lake effect snow events can produce extremely heavy snowfall rates, sometimes exceeding 2-3 inches per hour, and can lead to significant accumulations of over a foot in just 24 hours.
