The remnants of Hurricane Isaac passed through central Illinois on September 1st, triggering widespread showers and thunderstorms.  Due to strong low-level wind shear near a surface boundary stretched across north-central Illinois, many of the storms began to rotate and produce funnel clouds.  A total of seven tornadoes touched down across portions of Woodford, Marshall, and Stark counties around midday.  Most of the tornadoes were short-lived and did little or no damage.
