Summary:

Damage surveys confirmed an EF-0 tornado. A tornado developed near the intersection of Illinois Route 47 and Bonnie Lane and quickly moved east-northeast across a residential area of Yorkville.  Wind speeds quickly increased to around 80 mph causing the removal of shingles, fascia trim, and some siding from several homes along Kingsmill St. A fence was also heavily damaged.  Winds likely then eased somewhat as the tornado continued east-northeast causing some additional shingle damage as well as damaging several trees as it approached Illinois Route 126. The tornado continued across mainly open land along Illinois Route 71 before crossing Hilltop Road and causing additional shingle and trim damage to several homes in another residential subdivision.  The tornado then dissipated near or just northeast of Reservation Road with straight line winds continuing downstream.
