What phenomenon is often observed in Michigan during winter?

Lake-effect snow is a fascinating meteorological phenomenon common in Michigan during the winter months, particularly around the Great Lakes. This occurs when cold air moves over the relatively warmer waters of the lakes, picking up moisture and then depositing it as snow on the downwind shores. Given Michigan's significant shoreline along the Great Lakes, this effect results in localized heavy snowfall, especially in areas like the Upper Peninsula and the eastern part of the Lower Peninsula.

Factors contributing to lake-effect snow include the temperature difference between the air and the lake water, which enhances the moisture absorption, and the prevailing wind patterns that direct this moisture-laden air toward land. This localized snowfall can lead to much heavier accumulations in certain areas compared to regions further inland that may receive little to no snow. Therefore, lake-effect snow is not only a defining characteristic of winter in Michigan, but it also significantly impacts winter weather conditions, travel, and local ecosystems.
