May have caught the tail end of Stoughton Tornado II after racing out on the most impromptu chase ever. No convective outlook risk, no md, no watch, just a warning "TRAINED WEATHER SPOTTERS REPORTED A TORNADO NEAR STOUGHTON".
The possible funnel came early on when I was north of Stoughton looking south/southwest toward town at about 2:30 +/- 2 minutes. I got that only on video but my video capture hardware is broken so I can't put my video on the computer. I made a lousy quality video capture using the TV screen and my digital camera. It really looked much better than this.
My dad (making his first chase on Father's Day!) and I followed the storm's base on back roads between Stoughton and Edgerton. It appeared to be a mini-supercell but never really made any serious-looking attempts to produce after that. There were a lot of low-hanging clumps of scud floating around under and near the base so I would not be surprised that there were some sherrif/fake-nado reports. However I believe the initial reports were genuine especially in light of the damage reports with the other storm near Hartford.
The possible funnel is a little to the right of center in the crappy video capture.

Later views of the storm, first one is headed south toward the storm, in the second it has passed over us and we are looking back at it:

Law enforcement also observed this funnel and reported it. This storm produced the Calumet county tornado warning and its evolution with storms to its southwest later produced the Sheboygan county tornado warning. I went back and looked at radar and noticed a distinct outflow boundary from the storm/s I was following that headed south and when it interacted with the incipient convection of the Appleton storm, the storm blossomed and took on rotation. Lake boundary from Lake Winnebago may also have played a role in the increased rotation of the storm in far southeastern Outagamie county and far northwestern Calumet county.
