Tornado outbreak of September 21–23, 2006

Areas just outside Pilot Knob, a small town in Missouri, were affected by two separate F2 tornadoes that caused considerable damage.

The northern fringe of Metropolis in Illinois was also hit by a damaging F3 tornado in which homes were completely destroyed.

This was one of the most widespread non-tropical September outbreaks in United States history, yet no tornado-related deaths occurred (although 12 people were killed by other thunderstorm impacts).

In Arkansas, a woman died when a lightning bolt struck her boat and two other people were missing.

Finally, in Illinois, an apparent lightning bolt spark a house fire that killed two women.
