Weather History for May 8
 
2003   On I-24, state troopers blocked both sides of traffic to allow a tornado to pass near Paducah.

1840   At Natchez, MS at least 48 died on land and 269 on the river, most of those in sinking of flatboats, when a tornado struck. A piece of one steamboat was carried 30 miles.
