An NWS storm survey determined that there was an 8.5 mile long path of tree damage. Thunderstorm winds likely originated from a surging rear-flank downdraft associated with a mesocyclone embedded within a multicell storm line. Tree damage in the form of uproots and a mix of healthy and unhealthy snaps were common along the path. Most of the path length had EF-0 type of damage. In small sections of the path, damage was more in line with EF-1 estimated wind speeds in the form of several dozen trees snapped or uprooted. The worst damage was along M Drive S and K Drive S, near 10 Mile Road. Damage to property was relatively minor and ground surveys and tours of homes and farms with the property owners revealed no sign of debris deposited down the path into fields.
