The Impact of Lake Michigan on Chicago's Snowfall

Lake Michigan plays a significant role in Chicago's snowfall patterns, with the large body of water contributing to the city's snowbelt. As cold air moves over the lake, it picks up moisture, leading to significant snowfall totals along the lake's shoreline. This phenomenon is known as the "lake effect," and it can result in substantial snowfall totals in the city's northern and northwestern suburbs.

"The lake effect is a major factor in Chicago's snowfall patterns," notes Dr. Andrew Schultz, a meteorologist at the National Weather Service's Chicago office. "When cold air moves over Lake Michigan, it can pick up significant amounts of moisture, leading to heavy snowfall totals in the area."
