What the National Weather Service recorded

Widely scattered airmass thunderstorms popped up during the afternoon hours across south-central and southeast Wisconsin. One relatively long-lived storm pulsed to severe limits a couple times as it moved from Columbia County to extreme southeastern Jefferson County. Large hail was generated by this severe storm, however, no damage was noted. Synoptically, an upper-level trough moved southeast through Wisconsin during the afternoon, with a pool of colder air aloft. Maximum air temperatures at the surface rose into the upper 60s to upper 70s range across southern Wisconsin.
