The episode as NWS MKX wrote it up.
A Quasi-linear convective system with a cyclonic rotating comma head on the north end produced numerous tornadoes and damaging straight line winds. Governor Walker declared a State of Emergency for Green and Dane counties due to the extensive damage from severe thunderstorms and tornadoes that occurred from June 16-18.

NWS Milwaukee, WI wrote its last area forecast discussion before the first event at Jun 16, 6:52 PM CST, 3 hours 8 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI 752 PM CDT MON JUN 16 2014 .UPDATE... THE SHORT RANGE/HIGH RESOLUTION GUIDANCE HAD BEEN POINTING TO A LATER SHOW FOR THUNDERSTORMS THAN WHAT IS UNFOLDING THIS EVENING. BUT...IT/S NOT UNUSUAL FOR THESE MODELS TO BE SLOW WITH THE EVOLUTION. THE MCS OVER SOUTHERN MN/NRN IA IS ORGANIZING INTO A QLCS COMPLEX THAT IS EXPECTED TO ROLL INTO OUR FAR WESTERN COUNTIES BETWEEN 9 AND 10 PM THIS EVENING. IT/S CURRENTLY MOVING ABOUT 45 TO 50 MPH AND HAS NUMEROUS SEVERE THUNDERSTORM WARNINGS AND A FEW TORNADO WARNINGS CURRENTLY ALONG IT. THE AIRMASS OVER SOUTHERN WISCONSIN IS MOISTENING UP RAPIDLY AS THE WARM FRONT LIFTS NORTH. DEWPOINTS IN THE MID 60S ARE CREEPING NORTH JUST AHEAD OF THE LINE. BULK SHEAR IS IMPRESSIVE. SO...SEE NO REASON THAT AN EXTRAPOLATION OF THE CURRENT LINE EASTWARD WILL NOT BE EFFECTIVE. TYPICAL WITH THESE SYSTEMS...IT SHOULD EVOLVE INTO PRIMARILY A WIND EVENT WITH AN ISOLD TOR POSSIBLE. EVENTUALLY...AS WE HIT THE DIURNAL SLUMP...THE CONVECTION SHOULD LOSE IT/S PUNCH AS IT GETS INTO EASTERN WISCONSIN. WE/LL HAVE TO WAIT AND SEE ABOUT THAT. A COLD POOL/CDFNT WILL LAY OUT IN THE WAKE OF THIS LEADING CONVECTION THAT COULD BE THE FOCUS FOR MORE THUNDERSTORMS LATER TONIGHT INTO THE TUESDAY MORNING. WE/LL HAVE TO KEEP AN EYE ON TRENDS FOR THE POTENTIAL OF ANY FLOODING. IT WILL BE AN ACTIVE NIGHT...STAY UP TO DATE ON THE LATEST FORECASTS AND TRENDS ON RADAR. && .AVIATION/06Z TAFS/... LOOK FOR A LINE OF STRONG TO SEVERE THUNDERSTORMS TO HIT KMSN AROUND 04Z AND KMKE A FEW HOURS LATER. THESE STORMS WILL PRIMARILY GENERATE HIGH WINDS WITH HAIL A SMALLER THREAT. AN ISOLD TORNADO ISN/T OUT OF THE QUESTION. WINDS COULD GUST TO 60 MPH. ONCE THESE STORMS PASS THROUGH...WE COULD SEE MORE DEVELOP IN THE WAKE AS THE COLD POOL AND EFFECTIVE COLD FRONT ACT AS A FOCUS FOR MORE STORMS. THERE WILL BE A STRONG LOW LEVEL JET FEEDING RIGHT INTO THAT BOUNDARY. THINGS SHOULD QUIET DOWN BY 12Z TUESDAY WITH MUCH OF THE DAY ON TUESDAY QUIET. MORE STORMS MIGHT DEVELOP AGAIN TUESDAY EVENING. OF COURSE...IN ANY THUNDERSTORMS...BRIEF MVFR TO IFR CONDITIONS ARE POSSIBLE. && .PREV DISCUSSION... /ISSUED 345 PM CDT MON JUN 16 2014/ TONIGHT...FORECAST CONFIDENCE - MEDIUM. THE MKX FORECAST AREA IS STILL IN A SLIGHT RISK FOR SEVERE WEATHER FOR TONIGHT PER THE SPC DAY 1 OUTLOOK. THE MODERATE RISK COMES RIGHT UP TO OUR WESTERN BORDER. THE SCENARIO FOR TONIGHT LOOKS LIKE A LARGE AND STRONG THUNDERSTORM COMPLEX WILL ORGANIZE OVER CENTRAL MN THIS AFTERNOON AND THEN ACCELERATE SOUTHEAST THROUGH CENTRAL AND SOUTHERN WI FROM LATE EVENING THROUGH THE OVERNIGHT HOURS PER FORECAST CORFIDI VECTORS...THE MOVEMENT OF THE LOW LEVEL JET AXIS...AND DIFFLUENT THICKNESSES. MANY OF THE 12Z MESOSCALE AND SYNOPTIC MODELS HAVE COME IN WITH DECENT AGREEMENT WITH THE TIMING AND THE GENERAL TRACK OF THE THUNDERSTORM COMPLEX THROUGH CENTRAL AND SOUTHERN WI TONIGHT. PRECIPITABLE WATER VALUES WILL INCREASE TO AROUND 1.75 INCHES OVER SOUTHERN WI AS THE 50+ KNOT LOW LEVEL JET LEANS OVER INTO WI BETWEEN 00Z AND 06Z THIS EVENING. THIS IS WHEN THE THUNDERSTORM COMPLEX WILL ARRIVE...MOST LIKELY AROUND MIDNIGHT IN THE WESTERN FORECAST AREA AND 3 AM IN THE EAST. ROUGHLY 2000 J/KG OF CAPE AND 40 KNOTS OF BULK SHEAR SUPPORT STRONG THUNDERSTORMS. DAMAGING STRAIGHT-LINE WINDS ARE THE MAIN SEVERE WEATHER THREAT GIVEN THE LARGE...ORGANIZED CONVECTIVE COMPLEX THAT WILL LIKELY BE TRACKING THROUGH. MARGINALLY SEVERE HAIL IS POSSIBLE IN ANY EMBEDDED ORGANIZED THUNDERSTORMS. EXPECTED PWATS OF 1.75 INCHES TONIGHT ARE NEARLY 2 STANDARD DEVIATIONS ABOVE NORMAL FOR THIS TIME OF YEAR IN SOUTHERN WI. AREAS THAT GET A LOT OF RAIN TONIGHT WILL BE SUSCEPTIBLE FOR FLASH FLOODING AND AREAL FLOODING OVER THE NEXT FEW DAYS. TUESDAY...FORECAST CONFIDENCE - MEDIUM. MOST MODELS AGREE THAT THE OVERNIGHT THUNDERSTORM COMPLEX WILL HAVE EXITED EASTERN WI BY 7 AM TUESDAY MORNING. IT LOOKS LIKE A CAP WILL SET UP AROUND 700MB OVER SOUTHERN WI DURING THE DAY AND KEEP THE WEATHER WARM AND HUMID BUT QUIET. DESPITE CAPE BUILDING TO AROUND 3500 J/KG AND HIGH BULK SHEAR...WE WILL LIKELY LACK A STRONG ENOUGH TRIGGER TO GET THUNDERSTORMS TO DEVELOP UNTIL A SHORTWAVE COMES ALONG SOMETIME TUE EVENING. WENT WITH CHANCE POPS FOR THE AFTERNOON HOURS GIVEN THE VOLATILE ENVIRONMENT...THE PROXIMITY OF THE LOW LEVEL JET AND UNCERTAINTY IN THE EXACT LOCATION OR STRENGTH OF ANY MID LEVEL SHORTWAVES. TUESDAY NIGHT THROUGH THURSDAY...FORECAST CONFIDENCE - MEDIUM. THE HIGH COLUMN MOISTURE THAT WILL BE SURGING INTO SOUTHERN WI AND THE REGION TONIGHT IS EXPECTED TO REMAIN IN PLACE THROUGH THIS PERIOD. COLUMN PRECIPITABLE WATER VALUES WILL REMAIN IN THE 1.5 TO 1.8 INCH RANGE WHICH IS ABNORMALLY HIGH FOR MID-JUNE IN THIS AREA. STRONG FRONTAL BOUNDARY THAT WILL BE MOVING INTO THE VICINITY OF SRN WI ON TUESDAY WILL CONTINUE TO WAVER ACROSS THE REGION FROM NORTHERN ILLINOIS INTO CENTRAL WI DURING THIS PERIOD. EXACT LOCATION OF BOUNDARY EACH PERIOD DIFFICULT TO DETERMINE AND WILL BE AFFECTED STRONGLY BY NIGHT TIME CONVECTION AND ALSO PRESSURE RISE AREAS TO THE NORTH. ALSO THINK COLD LAKE MI WATERS MIGHT COME MORE INTO PLAY IN SUPPRESSING FRONT FARTHER SOUTH. HENCE WENT WITH COOLER TEMPS BY THE LAKE EACH DAY. SHORT TERM GUIDANCE ALL IN AGREEMENT ON CARRYING MID-LEVEL SHORT WAVE AND ENHANCED FORCING ACROSS SOUTHERN WI TUESDAY NIGHT. HENCE A SECOND NIGHT WITH A MCS LIKELY TO AFFECT PARTS OF SRN WI. BULK SHEAR WILL BE BORDERLINE FOR ROTATING UPDRAFTS SO INITIALLY SEVERE CONVECTION CLUSTER LIKELY TO TRANSITION TO HEAVY RAIN EVENT. LOW LEVEL JET NOT AS STRONG INTO WI AS TONIGHT WITH FOCUS TUE NGT FARTHER SOUTH AND WEST. ENHANCED FORCING FROM LOW LEVEL FRONTOGENESIS WED NGT INTO THU SO WL CONTINUE HIGH CHC/LOW LIKELY WORDING FOR CONVECTION. ISSUED HYDROLOGIC OUTLOOK FOR FLOODING POTENTIAL THIS WEEK. THURSDAY NIGHT THROUGH MONDAY - FORECAST CONFIDENCE - MEDIUM. THREAT FOR HEAVY RAINFALL AND CONVECTION WILL CONTINUE THU NIGHT AND FRIDAY AS WAVERING FRONTAL BOUNDARY REMAINS DRAPED ACROSS THE SOUTHERN WI AREA. MAY BE DEALING WITH RIVER AND AREAL FLOODING BY THAT TIME. MEDIUM RANGE GUIDANCE STILL SHOWING DIFFERENCES IN TIMING OF UPSTREAM CUT-OFF UPPER LOW MOVING EWD ACROSS THE UPPER MIDWEST. ECMWF STILL WEAKENS LOW INTO POSITIVELY TILTED UPPER TROF OVER THE GREAT LAKES WHICH WOULD CONTINUE TO CAUSE SCT CONVECTION THROUGH SATURDAY. BOTH GEM AND GFS SLOWER IN FILLING UPPER LOW AND DELAYS PASSAGE ACROSS THE WESTERN GTLAKES UNTIL LATE IN THE WEEKEND. MEDIUM RANGE GUIDANCE GRADUALLY CONVERGING ON SIMILAR SOLUTIONS HOWEVER...WHICH SHOULD EVENTUALLY BRING MORE WIDESPREAD DRIER WEATHER TO THE REGION FOR EARLY NEXT WEEK. BOTH GFS AND ECMWF HINTING AT POTENTIAL FOR FLOODING RAINFALL DIMINISHING AFTER FRONTAL OCCLUSION PASSAGE LATER FRIDAY. SLIGHTLY DRIER AIR WRAPPING AROUND UPPER LOW AND STATIONARY FRONT SHIFTING NORTH AND EAST MAY FOCUS HEAVY RAIN THREAT ELSEWHERE BY THE WEEKEND BUT WILL STILL NEED TO DEAL WITH SCT CONVECTION AS UPPER SHORT WAVES MOVE THROUGH WI. AVIATION/00Z TAFS/... VFR CONDITIONS EXPECTED THROUGH THE DAY TODAY. A LARGE THUNDERSTORM COMPLEX IS EXPECTED TO DEVELOP OVER CENTRAL MN THIS AFTERNOON AND TRACK ACROSS CENTRAL AND SOUTHERN WI OVERNIGHT TONIGHT. THEY ARE EXPECTED TO ARRIVE TO THE DELLS AROUND MIDNIGHT AND MILWAUKEE AROUND 3 AM. THE SYSTEM SHOULD EXIT EASTERN WI BY 7 AM. MVFR/IFR CONDITIONS EXPECTED IN THE POTENTIALLY WIDESPREAD AREA OF THUNDERSTORMS. WATCH FOR LOW LEVEL WIND SHEAR ALL NIGHT. SEVERE STRAIGHT-LINE WINDS AND HAIL ARE POSSIBLE OVERNIGHT. THERE IS A CHANCE FOR SHOWERS AND THUNDERSTORMS TO DEVELOP DURING THE DAY TUESDAY...BUT THEY WILL LIKELY HOLD OFF UNTIL THE OVERNIGHT HOURS WITH ANOTHER THUNDERSTORM COMPLEX. MARINE... SOUTHERLY WINDS AND WAVES WILL REMAIN BELOW SMALL CRAFT ADVISORY CONDITIONS. THUNDERSTORMS ARE EXPECTED TONIGHT AND AGAIN TUESDAY NIGHT. THEY MAY PRODUCE HIGH WINDS AND HAIL. && .MKX WATCHES/WARNINGS/ADVISORIES... WI...NONE. LM...NONE. && UPDATE...DAVIS TONIGHT/TUESDAY AND AVIATION/MARINE...MRC TUESDAY NIGHT THROUGH MONDAY...MBK
