Much needed beneficial rains hit all of south central and southeast Wisconsin the morning of August 16th, with almost all areas seeing at least a half inch of rain with many areas seeing more than inch. This was attributable to a passing cold front that brought periods of showers and thunderstorms to southern Wisconsin overnight and lasted into the mid-morning. Rain started at around 2:30 AM with showers and thunderstorms eventually tapering off at around 10:30 AM CDT.
