SUMMARY...

A tornado began near the intersection of county highway P and State Highway 23, just west of the Interstate 39 interchange, about 1.2 miles southwest of Endeavor in Marquette county.  The tornado moved north along a 1.78 mile long path, ending just under a mile northwest of Endeavor, about 1/2 mile north of Gail Avenue. The maximum damage path was 50 yards wide.  Trees were snapped along the path, with one falling on a house and vehicle, destroying the vehicle and damaging the roof on the house. Other homes had shingle damage with a section of metal roof peeled off a farm house.  The wind damage was consistent with an EF-0 tornado with winds of 70 to 85 mph.

The looped radar image below highlights how weak this particular storm was. It showed very little sign of rotation, indicative of a possible tornado. Given the rather small size of the storm, the small scale of the rotation and the distance from the radar, it is not unusual for our doppler radar to not see rotation suggesting a possible tornado. Thankfully, these types of tornadoes do very little widespread damage, thus limiting their ability to hurt people. 

The track of the tornado is shown as the small vertical line in Cyan color (and circled).
