Weather History for August 3
 
1885
A tornado hit Philadelphia and Camden along its eight mile path. (David Ludlum)

1988
Thunderstorms developing ahead of a slow moving cold front produced severe weather from the Central High Plains to the Upper Great Lakes Region. Thunderstorms around Fort Collins, CO, produced wind gusts to 74 mph along with marble size hail. Sixteen persons were injured in the storm, most of whom were accidently locked out of their office building, having evacuated it when the fire alarm went off, apparently triggered by lightning. (Storm Data) (The National Weather Summary)
