Our snow storm last Wednesday dropped a trace of snow in Tucson and over 4 inches in places like Oracle. One the storm moved into the Midwest, it became a monster. Many areas from Colorado to Arkansas saw heavy snow. So much snow came down, it blanketed large areas of the Midwest. Here is a picture from space (taken at night) from NASA. This image shows the extent to which the snow covered the ground and was lit up by the moon and starlight.

Early on the morning of February 22, 2013, the Suomi NPP satellite captured this nighttime view of heavy snow over the United States. In many towns and cities across the Great Plains, more than a foot of snow fell. Kansas bore the brunt of the storm, with as much as 22 inches falling in the town of Russell.
The day-night band takes advantage of moonlight, airglow (the atmosphere's self-illumination through chemical reactions), zodiacal light (sunlight scattered by interplanetary dust), and starlight from the Milky Way. By using these dim light sources, the day-night band can detect changes in clouds, snow cover, and sea ice. When the image was acquired, the moon was in its waxing gibbous phase, meaning it was more than half-lit, but less than full.
