A severe winter storm blustered its way across the United States on December 7 and 8, 2009. The storm dumped heavy snow from California to the Great Plains, and fierce winds added to the hazardous conditions. The storm was predicted to continue eastward in midweek, and blizzard warnings were in effect for Great Lakes states as of December 9.
This image shows the blanket of snow laid down by the storm across the West, along with the thick swirl of storm clouds over the Great Plains from North Dakota to Oklahoma. The image is made from a combination of images captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) sensors on NASA’s Terra (most of the left side of the image) and Aqua (most of the right side) satellites on December 8.
