(The dates used below assume Thunder Over Louisville was held two Saturdays before the Kentucky Derby, with the exception of years in which that weekend was Easter weekend when Thunder was moved to the week before, and except for the 1990 Thunder since Thunder's web page indicates the event was held on April 17 that year.)
Data listed here were taken from the nearest official observing site for the city of Louisville, not at the venue site itself.
