<P> Although the period in which most tornadoes strike ( `` tornado season '' ) is March through June , tornadoes - including violent tornadoes and major tornado outbreaks - have been documented in the United States during every month of the year . Two examples of this are when a series of tornadoes hit the state of Indiana on November 22 , 1992 , and injured at least nine people . Another notable non-season tornado was where a tornado struck the area of McLean County , Illinois . Even though the tornado was during a winter month , it blew 20 railroad cars off their tracks , and hauled a camper over 100 yards ( 91 m ) . </P>
