The path drawn at its surveyed width of 75 yards (0.04 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

Tornado started just south of Decatur Lake and tracked to the north through Decatur Lake Golf Course, causing some minor tree damage. Further to the north, a barn had roof damage with a number of sheets of metal lofted off of the building. Tornado tracked into a small portion of Rock County before disapating.

The wider storm

A warm front was draped across southern Wisconsin on the evening of March 31st which had numerous thunderstorms develop along it. Most of the stronger storms that interacted with the warm front ended up producing some brief EF-0 to EF-1 tornadic damage. There were a few incidents that looked to be from straight line winds along the southeast side of the rotations, but most of the damage appeared to be lofted and from tornadoes.

Began near Brodhead (42.6368, -89.4121).
