Why do some winters bring lake-effect snow near large lakes?
WeatherSnow
Quick Answer
Cold air moving over relatively warmer lake water picks up moisture and heat, then dumps snow downwind when it reaches colder land. This can create narrow, intense snow bands.
The Full Story
Lake-effect snow forms when very cold air masses pass over unfrozen water, often in late autumn or early winter. The lake adds moisture and warmth to the air, causing clouds to form quickly. Once that air reaches land, it cools and drops snow in concentrated bands that can bury one town while leaving another nearby much less affected. The Great Lakes region of North America is famous for this effect, especially along the shores of Lakes Erie and Ontario.
Key Facts
1.Lake-effect snow is strongest when the water is much warmer than the air
2.Snow bands can be very narrow and highly localized
3.The Great Lakes are a major lake-effect snow region
