Weather History for November 20
 
1914
The high temperature of 28 degrees at Atlanta, GA, was their earliest daily high below the freezing mark. (The Weather Channel)

1988
Thunderstorms developing ahead of a fast moving cold front produced severe weather in the Upper Ohio Valley and the Middle Atlantic Coast Region during the afternoon and early evening. Thunderstorm winds gusted to 69 mph at Kennedy Airport in New York City, and winds along the cold front itself gusted to 56 mph at Cincinnati OH. The same storm produced snow in Kansas, Missouri and Illinois, with eight inches reported at Rolla MO. (The National Weather Summary) (Storm Data)
