The episode as NWS GRB wrote it up.
An unstable air mass combined with an upper level disturbance and a weak surface boundary to produce thunderstorms. Some of the storms produced large, destructive hail and isolated wind damage. Quarter to golf ball size hail damaged vehicles in Rhinelander (Oneida Co.), but east central Wisconsin was hardest hit by the storms. Thunderstorm winds downed trees and power lines in the Birnamwood (Shawano Co.) and Clintonville (Waupaca Co.) areas, and golf ball to tennis ball size hail caused considerable damage to vehicles, homes and businesses around the city of Manitowoc (Manitowoc Co.).

NWS Green Bay, WI wrote its last area forecast discussion before the first event at Jun 27, 11:35 AM CST, 2 hours 35 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 1235 PM CDT THU JUN 27 2013 UPDATED AVIATION PORTION FOR 18Z TAF ISSUANCE .SYNOPSIS... ISSUED AT 340 AM CDT THU JUN 27 2013 THUNDERSTORMS TODAY...SHOWERS FRIDAY...THEN COOLER AND LESS HUMID. MAJOR LARGE SCALE CHGS UNDERWAY. UPR ANTICYCLONE HAS BECOME ESTABLISHED ACRS THE 4 CORNERS REGION...AND A MAJOR AMPLIFICATION OF THE UPR PATTERN ABOUT TO GET UNDERWAY. STG RIDGE WL BUILD NWD FM THE 4 CORNERS HIGH THE NEXT FEW DAYS...HELPING TO FORCE DOWNSTREAM TROFFING TO BECOME ESTABLISHED ACRS THE GREAT LAKES RGN. NEXT WEEK THE UPR FEATURES WL RETROGRADE A BIT...WITH THE HIGH SHIFTG NWWD INTO THE INTERMOUNTAIN WEST...AND THE CENTER OF THE TROF PULLING BACK TOWARD THE MID-MISSISSIPPI VALLEY. THE UNSEASONABLY AMPLIFIED PATTERN WL CONT THROUGH THE END OF THE FCST PERIOD...THOUGH THE STRENGTH OF THE FLOW ACRS THE CONUS WL WEAKEN MARKEDLY AS THE MAIN WESTERLIES REFORM WAY N ACRS CANADA. THE WARM MOIST AIR ACRS THE AREA WL BE REPLACED BY COOLER AND DRIER CANADIAN AIR AS THE UPR TROF EVOLVES TO OUR E. THAT SHOULD DROP TEMPS DOWN TO A LITTLE BLO NORMAL BY THE WEEKEND...THOUGH THEY SHOULD REBOUND TO NR NORMAL AS THE FLOW OF FRESH CANADIAN AIR COMES TO AN END WHEN THE TROF RETROGRADES NEXT WEEK. THE BULK OF THE PCPN WL OCCUR EARLY IN THE PERIOD...AND SHOULD BE SUFFICIENT TO RESULT IN NR NORMAL AMNTS IN MOST AREAS. && .SHORT TERM...TODAY...TONIGHT...AND FRIDAY ISSUED AT 340 AM CDT THU JUN 27 2013 SML CLUSTER OF HEAVY RAIN PRODUCING TSRA SHOULD EXIT E-C WI EARLY THIS MORNING. JUST SOME ISOLD SHRA REMAINING ACRS THE REST OF THE AREA. A FEW CLUSTERS OF TSRA WERE OCCURRING BACK IN MN IN ASSOC WITH SHRTWV SLIDING EMBEDDED IN STRENGTHENING WNWLY FLOW ALOFT. MAIN CONCERN TDA IS PCPN CHCS AND SVR POTENTIAL. ALTHOUGH PATCHES OF CLDS WL BE ARND THIS MORNING...THERE SHOULD BE AT LEAST SOME SUN. HUMIDITIES MAY BE DOWN A NOTCH FM YDA...BUT SFC DWPTS SHOULD STILL BE IN THE MIDDLE TO UPPER 60S ACRS MOST OF THE AREA. GIVEN COOLING EXPECTED TO OCCUR ALOFT...THAT SHOULD YIELD 2K-3K J/KG CAPES ACRS THE AREA BY AFTN. DEEP LAYER SHEAR WL ALSO BE INCRG...WITH 30-50 KTS EXPECTED BY MID-AFTN. SHEAR PROFILE WL BE CHARACTERIZED BY STRAIGHT-LINE HODOGRAPHS...WHICH FAVOR SPLITTING CELLS. THERE ARE ALSO SOME INDICATIONS THAT SFC WINDS MAY BRIEFLY BACK IN RESPONSE TO WK BOUNDARY THAT WL BE PUSHING ACRS THE FCST AREA...POSSIBLY AUGMENTING THE SHEAR EVEN A BIT MORE. THE STRONGEST SHEAR WL BE OVER THE SW PART OF THE FCST AREA...BUT THE BETTER LARGE-SCALE FORCING WL BE OVER THE NE. SO IT/S TOUGH TO DELINEATE THE PORTION OF THE FCST AREA THAT IS MOST AT RISK FOR SVR WX. SLGT RISK IN THE SPC SWODY1 PRODUCT THAT PRETTY MUCH COVERS THE AREA SEEMS RIGHT ON TARGET. THE MAIN RISKS WL BE OF LARGE HAIL AND DAMAGING WIND GUSTS. WHILE BRIEF HEAVY RAIN IS CERTAINLY POSSIBLE WITH ANY THUNDERSTORM...THE INCREASING SHEAR SHOULD DECREASE THE THREAT OF EXCESSIVE RAINFALLS AND FLOODING. TOOK POPS UP FM ISOLD CATEGORY EARLY TDA TO LIKELY FOR THE AFTN. THEN DECREASED THEM AGAIN THIS EVENING...THOUGH IT/S TOUGH TO RULE OUT AT LEAST ISOLD SHRA CONTG ALL NGT. DIURNAL DESTABILIZATION COMBINED WITH STRONGER FORCING SWINGING ARND WRN PORTION OF DEVELOPING GREAT LAKES UPR TROF SHOULD RESULT IN AN INCREASE IN PCPN AGAIN FRI. OPTED TOWARD THE COOLER OF THE GUID TEMPS FRI AS THERE SHOULD BE PCPN...PLENTY OF CLDS...AND A DEVELOPING SFC FLOW. .LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY ISSUED AT 340 AM CDT THU JUN 27 2013 MDLS CONT TO INDICATE A STRONGLY AMPLIFIED FLOW WELL INTO NEXT WEEK WITH A PROMINENT WRN CONUS UPR RDG AND AN E-CNTRL CONUS UPR TROF. ONLY NOTICEABLE CHANGE TO OCCUR TOWARD THE MIDDLE OF NEXT WEEK WL BE THE UPR TROF RETROGRADING CLOSER TO THE CNTRL CONUS. COOLER/LESS HUMID AIR MASS TO OVERSPREAD WI THIS WEEKEND... BUT WL HAVE TO DEAL WITH A COUPLE MORE PERIODS OF PCPN INITIALLY AS A MID-LEVEL TROF SWINGS THRU THE AREA. THIS MID-LEVEL TROF IS FCST BY THE MDLS TO ROTATE SOUTH TOWARD SRN SECTIONS OF THE GREAT LAKES REGION FRI NGT WITH VARIOUS PIECES OF SHORTWAVE ENERGY MOVING THRU THE TROF ITSELF. THESE FEATURES...WHEN COMBINED WITH A COOL/CYCLONIC FLOW IN PLACE OVER THE AREA...WL LEAD TO A CONTINUATION OF PCPN CHCS OVER NE WI. THESE PCPN CHCS WOULD THEN CARRY OVER THRU AT LEAST SAT MORNING AS THE MID-LEVEL TROF CONTS TO SLOWLY SAG FARTHER SOUTH. THE CYCLONIC FLOW LINGERS THRU MUCH OF SAT...THUS A FEW SHWRS COULD HANG ON INTO SAT AFTERNOON ESPECIALLY OVER CNTRL/E-CNTRL WI. NRN WI MAY BE ABLE TO SEE SOME LATE DAY SUN AS DRIER AIR BEGINS TO ADVECT INTO THE REGION BEHIND THE DEPARTED MID-LEVEL TROF. MAX TEMPS ON SAT WL BE BELOW NORMAL AS COOL N-NE WINDS TO PREVAIL WHICH WL KEEP READINGS IN THE LOWER TO MIDDLE 70S. THIS DRIER AIR MASS TO OVERSPREAD ALL OF WI BY SAT EVENING AS THE MAIN UPR TROF DIGS FARTHER SOUTH TOWARD THE GULF OF MEXICO. DEW PTS ARE EXPECTED TO DROP INTO THE MID TO UPR 40S NORTH/LOWER 50S CNTRL AND E-CNTRL WI...THUS A MUCH MORE COMFORTABLE AIR MASS TO BE IN PLACE SAT NGT. A WEAK AREA OF HI PRES IS THEN FCST TO DROP SOUTH OUT OF WRN ONTARIO FOR SUNDAY AND SHOULD KEEP A PLEASANT DAY ON TAP OVER NE WI WITH ONLY SOME FAIR WEATHER CUMULUS CLOUDS AND MODEST NE WINDS TO CONTEND WITH. TEMPS WL REMAIN SLIGHTLY BELOW NORMAL WITH MUCH OF NE WI REACHING THE MID 70S. THE HI PRES IS PROGGED TO EXTEND FROM JAMES BAY SW TO THE UPR MS VALLEY THRU MON...THEREBY KEEPING THE TRANQUIL/COMFORTABLE WEATHER CONDITIONS INTACT OVER THE FCST AREA. MAY ACTUALLY NEED TO LOWER MIN TEMPS SUNDAY NGT A COUPLE OF DEGS AS THE AIR MASS REMAINS DRY AND WINDS APPEAR TO BE ABLE TO DECOUPLE. WOULD NOT AT ALL BE SURPRISED TO SEE A FEW COLDER LOCATIONS DIP TOWARD THE 40 DEG MARK (I.E. LNL). MON'S MAX TEMPS SHOULD END UP SIMILAR TO SUNDAY'S. FCST BECOMES MORE COMPLEX HEADED INTO TUE AS THE E-CNTRL UPR TROF IS PROJECTED TO BEGIN A SLOW RETROGRADE WWD TOWARD THE WRN GREAT LAKES/UPR MIDWEST. AM WORRIED THAT COOLER AIR ALOFT MAY ALLOW FOR ENUF INSTABILITY TO DEVELOP TO HAVE AT LEAST ISOLATED SHWRS OR EVEN A TSTM TO POP UP DURING PEAK HEATING. MAY EVENTUALLY NEED TO ADD A LOW-END POP...BUT SINCE THE EXACT LOCATION OF THE UPR TROF STILL IN DOUBT...PREFER TO KEEP TUE DRY FOR NOW. LONG RANGE MDLS EVENTUALLY CLOSE OFF AN UPR LOW SOMEWHERE OVER THE NRN PLAINS BY NEXT WED. SOMEWHAT OF A RETURN FLOW TO BE IN PLAY AS WELL ON WED AS THE MEAN FLOW TO BE FROM THE SW. THIS ADDED MOISTURE... COMBINED WITH THE COOL AIR ALOFT COULD STILL DEVELOP SOME SHWRS/ ISOLATED TSTMS OVER THE REGION. HAVE KEPT ANY POPS VERY LOW DUE TO THE UNCERTAINTY OF HOW THIS TRANSITION WL PLAY OUT. && .AVIATION...FOR 18Z TAF ISSUANCE ISSUED AT 1234 PM CDT THU JUN 27 2013 SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON ACROSS MOST OF NORTH-CENTRAL AND NORTHEAST WISCONSIN. ANY THUNDERSTORMS WILL HAVE POTENTIAL TO CREATE STRONG GUSTY WINDS AND NEAR SEVERE HAIL. STORMS WILL CONTINUE TO MID TO LATE EVENING BEFORE DISSIPATING. THEN AN UPPER LEVEL LOW PRESSURE SYSTEM WILL DROP SOUTH ACROSS THE REGION LATE TONIGHT INTO SATURDAY.
