On February 11, 2016, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, acquired this natural-color image of the cloud streets over the Great Lakes.

These long, parallel bands of cumulus clouds form along cylinders of rotating air. But first, cold air from the northwest had to pass over the comparatively warmer lake water, imparting warmth and moisture into the rising air mass. Read more about cloud streets and their formation here and here.
