Central IL tornado climatology updated

The NWS office in Lincoln, IL has updated their tornado climatology for central and southeastern Illinois for the period 1950-2009. During this period McLean County reported an incredible 100 tornadoes, the highest for any county in central Illinois. However, McLean County is the biggest county in this area (a bigger county means a bigger target). This can be partially overcome by calculating a tornado density instead. In that case, Logan County ranks highest in the area with an average of 9.385 tornadoes per 100 square miles.
