The episode as NWS GRB wrote it up.
Slow moving thunderstorms, in a moist and very unstable air mass in the vicinity of a nearly stationary front, produced isolated wind damage and minor flooding in central Wisconsin. Rainfall from the storms was heavy enough to cause street flooding near and west of Edgar (Marathon Co.) and in Birnamwood (Shawano Co.).
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Green Bay, WI wrote its last area forecast discussion before the first event at Jul 27, 2:08 PM CST, 2 hours 2 minutes earlier.
Area Forecast Discussion National Weather Service Green Bay WI 308 PM CDT WED JUL 27 2016 Forecast discussion for routine afternoon forecast issuance .SHORT TERM...Tonight and Thursday Issued at 306 PM CDT Wed Jul 27 2016 An upper trough will move across the region during the late afternoon and evening hours, while a surface cold front also drops south across the area. Some scattered thunderstorms are expected during the mid afternoon hours as the air begins to destabilize again after earlier clouds and precipitation. More organized convection over western Wisconsin will move into our area during the late afternoon and probably weaken during the evening as surface heating is reduced. Still could get some decent wind gusts and some hail. Main threat is likely heavy rain with local 1 to 2 inch amounts possible. Drier air will arrive from the north Thursday with the chance of showers and isolated thunderstorms limited to areas south of highway 29. Highs will be at or below normal with lower relative humidity than the last few days. .LONG TERM...Thursday Night Through Wednesday Issued at 306 PM CDT Wed Jul 27 2016 Any lingering showers should shift out of our southern counties Thursday evening, as Canadian high pressure and associated drier air edges into the forecast area. Although a few models generate spotty and weak afternoon convection at times, the general concensus is for a dry period from Friday through Monday, along with a gradual warming trend. As the Canadian high shifts east Monday night into Tuesday, southerly return will lift a warm front toward the forecast area, resulting in a chance of thunderstorms. The chance of storms will linger through the middle of the week. Very warm and muggy conditions appear poised to return during this period, along with potential for locally heavy rainfall, as precipitable water values increase to around 2 inches. && .AVIATION...for 18Z TAF Issuance Issued at 102 PM CDT Wed Jul 27 2016 A cold front dropping slowly south across WI will produce showers and thunderstorms at times this afternoon and tonight. VFR ceilings and visibilities expected outside of any precipitation this afternoon and evening but MVFR conditions expected late tonight and early Thursday. && .GRB WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM.....RDM LONG TERM......Kieckbusch AVIATION.......RDM
