when was there a tornado
Tornado Alley, as that part of the central U.S. has come to be known, reaches across parts of Texas, Oklahoma, Kansas, Missouri, East Nebraska, and West Iowa. In Minnesota, tornadoes have occurred in every month from March through November. The earliest verified tornado in Minnesota occurred on March 18, 1968, north of Truman, and the latest in any year on November 16, 1931, east of Maple Plain. Historically and statistically, June is the month of greatest frequency with July not far behind.
