This Date in Weather History

1987 - A powerful storm spread heavy snow from the Southern High Plains to the Middle Mississippi Valley, and produced severe thunderstorms in the Lower Mississippi Valley. During the evening a tornado hit West Memphis TN killing six persons and injuring two hundred others. The tornado left 1500 persons homeless, and left all of the residents of Crittendon County without electricity. Kansas City MO was blanketed with 10.8 inches of snow, a 24 hour record for December, and snowfall totals in the Oklahoma panhandle ranged up to 14 inches. Strong winds, gusting to 63 mph at Austin TX, ushered arctic cold into the Great Plains, and caused considerable blowing and drifting of snow.
