What the National Weather Service recorded
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.
