O'Fallon Illinois Sick Thunderbolt Tornado Siren Test

Description

This is one of the Thunderbolts in O'Fallon, IL (in the process of being replaced) during a monthly test. This should be a steady signal, but the poor condition of the chopper motor (and its electrical connection) are likely leading to the undulating sound.
