Under the Lens: Is Wisconsin seeing more heavy rain events?

One of the anticipated impacts of climate change in Wisconsin is an increase in extreme storms and subsequent flood events. Those of us in southern Wisconsin got a taste of this from the storm last August that dropped nearly of a foot rain in parts of Dane County, and many other areas of the state experienced similar heavy rain events. While it is impossible to definitively attribute a particular event to climate change, is there any evidence that we are already experiencing more heavy rain events?
