MADISON — Don't be alarmed when you hear sirens go off Friday afternoon.
Wisconsin’s statewide tornado drill was delayed until Friday because of the threat of severe thunderstorms, hail or tornadoes Thursday in southern Wisconsin.
A mock tornado watch has been issued for 1 p.m. Friday and will be followed by a statewide mock tornado warning at 1:45 p.m. and a second mock tornado warning at 6:45 p.m.
The decision only affects the test alerts that will be sent out over NOAA weather radios and through participating TV and radio stations around the state.
