Lake Effect Snow Warning: What To Do?

Lake effect snow is a localized weather phenomenon that can produce significant snowfall in a short period. If you're under a lake effect snow warning, understanding the risks and taking precautions is crucial. This guide provides essential information about lake effect snow, how warnings are issued, and steps you can take to stay safe.

What is Lake Effect Snow?

Lake effect snow occurs when cold, dry air passes over a relatively warm lake. The warm lake water heats the lower layer of air, adding moisture and instability. As this air mass moves over land, it cools and the moisture condenses, forming clouds and snow. The narrow bands of intense snowfall can result in very high accumulation totals in localized areas.

Key Factors Contributing to Lake Effect Snow:

• Cold Air Mass: A frigid air mass is necessary to create a significant temperature difference between the air and the lake water.
• Warm Lake Water: The lake's surface temperature must be significantly warmer than the air passing over it (typically 13°C or 25°F difference).
• Wind Direction: A consistent wind direction is needed to transport the air mass across the lake and over land. The longer the air travels over the lake (fetch), the more moisture it can pick up.
• Terrain: Topography, such as hills and higher elevations, can enhance snowfall by causing the air to rise and cool further.

Regions Affected by Lake Effect Snow

Lake effect snow is most common downwind of the Great Lakes in North America, including: — Zach Edey Game Log: Stats, Highlights, And Impact
