The great "Tri-State Tornado" occurred, the most deadly tornado in U.S.
history. The tornado claimed 695 lives (including 234 at Murphysboro IL and
148 at West Frankfort IL), and caused seventeen million dollars property
damage. It cut a swath of destruction 219 miles long and as much as a mile
wide from east central Missouri to southern Indiana between 1 PM and 4 PM.
The tornado leveled a school in West Frankfort IL, and picked up sixteen
students setting them down unharmed 150 yards away. Seven other tornadoes
claimed an additional 97 lives that day. (David Ludlum)
...1971...
High winds accompanied a low pressure system from the Rocky Mountains to
the Great Lakes. Winds gusted to 100 mph at Hastings NE, and reached 115
mph at Hays KS. High winds caused two million dollars damage in Kansas.
Fire burned 50,000 forest acres in eastern Oklahoma. (17th-19th) (The
