EF1 tornado in Macoupin County, Illinois

A tornado touched down over the Country Classic Cars business northeast of Staunton, IL. Many videos surfaced showing a funnel develop and pass over Interstate 55. No damage could be seen west of the interstate, creating the initial damage to a carport at the business, and then cutting an approximately 50 yard path through the middle portion of the second storage shed on the property. The tornado proceeded east, depositing several pieces of sheet metal and wood onto Old Route 66 and fields to the east. Despite visible power flashed in videos, power lines looked untouched. Arching likely occurred when metal sheeting was thrown across the lines. A debris path could be seen strewn for several hundred feet to the northeast. A house, couple of farm buildings and trees were damaged on the south side of Tall Timber Road. Another structure to the north side of Tall Timber Road, at the end of Adden Road, was also damaged. Several pieces of debris could be seen in the field to the northeast of Adden Road and to the west of Two Mile Road. However, no damage was assessed past the field, where it is likely the tornado dissipated. Additional videos from Mt. Olive show a long rope funnel ascended above the town with no damage to the community. Overall the tornado was rated EF1 with a path length of 1.39 miles and a max path width of 50 yards. No injuries or deaths were reported with this tornado.

By late morning much of the rain shifted north and east of forecast area allowing partial

clearing to destabilize the atmosphere. Steep lapse rates due to relatively cold mid level temperatures southeast of the upper level low combined with strong low-mid level wind shear due to an 80-kt mid level wind max southeast of the upper level low. This led to the development of isolated low topped supercells along the northward moving warm front and ahead of the eastward moving cold front. Eight tornadoes were surveyed over WFO LSX's forecast area.
