A series of powerful storms affected the southwestern US during the 18-23 January 2010 period, which resulted in record rainfall and snowfall in parts of northern Arizona. Flagstaff recorded 54.2 inches of snow, which was their 2nd largest storm total snowfall on record. A 250-meter resolution MODIS true color image from the SSEC MODIS Today site (above) showed the coverage of snow across the higher elevations of northern Arizona on 25 January 2010.

On the following day, a comparison of AWIPS images of the MODIS visible channel and a false-color Red/Green/Blue (RGB) image (below) shows that most of the bright features seen on the visible were snow cover (which shows up as darker pink features on the false color image).
