As of the last news posting on the NWS site, there are some new data from that storm from the NWS. Data provided by the NWS Milwaukee Sullivan website.

Full story is at :

A 5" measured hail stone was observed 2 miles ENE of Delafield in Waukesha County (3rd largest in Wisconsin History)
A 3.25" measured hail stone was observed and reported to our skywarn group 2 miles west of Waukesha in Waukesha County.
(both have photos of the large hailstones on the NWS website)
