The June 10, 2016 severe storms that produced widespread wind damage across north-central and northeast Wisconsin also produced a weak tornado near Mackville in Outagamie County.

Radar and photographic evidence indicated a weak tornado (EF0) developed southwest of Mackville, about four miles north of Appleton, around 8:00 pm. The tornado formed as thunderstorms from the west moved over an old storm outflow boundary that was over the area. Except for a few tree branches, no damage was reported with the tornado.

NWS Doppler radar images shortly after 8:00 pm on June 10. A small but pronounced velocity couplet and tornado debris signature (TDS) can be seen. The tornado photo was taken by Josh Vandewettering. Click image for larger view.
