Huge Storm Blankets U.S. December 19-21 (Video)

Much of the U.S. was blanketed by this large storm in December 2012.

This NOAA’s GOES-13 satellite animation shows movement of the storm from Dec.19 through the morning of Dec. 21.

The long line of clouds is a cold front associated with a low pressure center that moves in from the west as the animation begins and reaches northern Ohio by the time the animation ends on Dec. 21 at 9:45 a.m. EST.
