On February 5-6th and 9-10th of 2010 two series of winter storms pummeled the Northeast United Sates. These two systems combined left over 70 inches of snow in some areas, and broke records for snowfall in Washington, DC. This animation shows the infrared imagery collected from the NOAA GOES-12 satellite during that time. A color enhancement is used to indicate the strength of the storms as they move across the continent. Since the satellite detects differences in temperature (infrared energy), cold, white areas can also be seen on the ground as the storms pass and cover the land with snow and ice.
