Just look at that! A higher-resolution of the image can be seen here. From the article that goes with it:
"A severe winter storm hammered the Midwestern United States on December 1, 2006. According to news reports, the storm iced roads, canceled flights, broke tree branches, left more than two million homes and businesses without electricity, and temporarily shut down part of Interstate 40 in central Oklahoma. Several deaths were linked to the storm, including deaths from traffic accidents and carbon monoxide poisoning.
The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard NASA’s Terra satellite captured this image of the storm’s aftermath on December 3, 2006. By the time MODIS took this picture, the storm had moved off to Canada, and skies over the U.S. Midwest had largely cleared. In this image, the lingering snow looks like a giant finger-paint smear of white on a tan background. Streaks of clouds hover in the east, and lighter cloud cover remains in the north."A KMZ file of the snow storm is available for Google Earth.
