This Day in Weather History: December 15
In 1969, a persistent one-week siege of inversion-related fog began in northern Utah. Limited visibility caused one traffic death and two aircraft deaths. In 2000, a thunder-laden storm dumped up to 18 inches of snow at Powder Mountain. Winds also gusted to 114 mph atop Mt. Baldy at Alta.
