Unsettled weather and cold Canadian air swept over the northern U.S.
states of Michigan and Wisconsin repeatedly during the month of
November 2021, starting with the first snowfall of the year early in
the month. By November 30, when the Moderate Resolution Imaging
Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired this
true-color image, the final system of the month had dropped light snow
on Wisconsin (west) and heavier, lake-effect snow was still falling
across Michigan. Snow-filled cloud hangs over eastern Lake Michigan and
hides most of western Michigan from view in this image.
Lake-effect snow occurs along the southeastern edge of the Great Lakes
when icy wind blows across the lakes from Canada. The wind picks up
relatively warm, moist air over the lakes and pushes it over land,
where the air is cooler. When the moist air encounters cooler
temperatures over land, the water condenses into precipitation. In this
case, the cold air crossed Lake Michigan and the precipitation fell as
snow.
