The episode as NWS MQT wrote it up.
A cold front moving through a very moist and unstable air mass produced severe thunderstorms in the Iron Mountain-Norway area of Dickinson County during the early morning of the 10th.
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 Marquette, MI wrote its last area forecast discussion before the first event at Jun 10, 12:53 AM EST, 10 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 153 AM EDT WED JUN 10 2015 .UPDATE... ISSUED AT 928 PM EDT TUE JUN 9 2015 ...SEVERE TS THREAT FOR UPR MI SEEMS TO BE DIMINISHING... LTG ASSOCIATED WITH CLUSTER OF SHOWERS/TS OVER NE MN MOVING QUICKLY INFO FAR NW LK SUP REMAINS RATHER LIMITED. RAP/SPC ANALYSIS INDICATES MUCAPE IS LIMITED OVER WRN LK SUP/UPR MI...NO MORE THAN 250-500 J/KG. RESPONSIBLE FACTORS INCLUDE WARM MID LVL TEMPS/INVRN ARND H6 SHOWN ON THE 00Z INL RAOB AND LIMITED MSTR INFLOW INTO THE AREA. LOSS OF DAYTIME HEATING WL NOT BE FAVORABLE AS WELL. AS A RESULT...SPC HAS DOWNGRADED THE SVR TS RISK FOR UPR MI TO MARGINAL. HOWEVER...DEEP 0-6KM WIND SHEAR REMAINS FAVORABLE...AS HI AS 40 TO 45 KTS. WITH WELL MIXED ATMOSPHERE/HI DCAPE AOA 1000 J/KG ESPECIALLY NEAR THE WI BORDER...CANNOT RULE OUT SOME VERY GUSTY WINDS WITH ANY STRONGER CELLS THAT MOVE INTO UPR MI. BUT THE OVERALL SVR THREAT APPEARS TO BE MORE LIMITED THAN EARLIER EXPECTED. && .SHORT TERM...(THIS EVENING THROUGH WEDNESDAY) ISSUED AT 348 PM EDT TUE JUN 9 2015 A SHORTWAVE AND ASSOCIATED SFC LOW OVER NWRN ONTARIO WILL MOVE ACROSS NRN ONTARIO TONIGHT AND WED. A SECOND SHORTWAVE OVER THE MANITOBA/SASKATCHEWAN BORDER WILL DIVE ACROSS THE AREA TONIGHT AT THE SAME TIME THAT A SFC FRONT MOVES THROUGH. PRECIP DEVELOPED OVER MN AND FAR NWRN WI THIS MORNING AND AFTERNOON...BUT DISSIPATED BEFORE IT MOVED WEST INTO THE CWA. IT APPEARS LOW LEVEL MOISTURE IS TOO LOW AND CIN TOO HIGH FOR MEANINGFUL CONVECTION TO DEVELOP WITHOUT MORE SIGNIFICANT FORCING. THAT FORCING IS EXPECTED TO BE MET AS THE SHORTWAVE AND FRONT MOVE THROUGH LATE THIS EVENING AND EARLY TONIGHT. MODELS SHOW MLCAPES DECREASING WITH A LOSS OF DAYTIME HEATING EARLY THIS EVENING...BUT THEN INCREASING TO 700-1200J/KG OVER THE WRN HALF OF UPPER MI AS THE SHORTWAVE MOVES IN. MODELS ALSO SHOW DCAPE VALUES IN EXCESS OF 1000J/KG OVER THE WRN HALF. THE SHORTWAVE WILL ALSO INCREASE THE SHEAR...WITH STRONG 0-1KM BULK SHEAR OF 25-35KTS AND BOTH 0-3KM AND 0-6KM SHEAR OF 40-50KTS. CONDITIONS APPEAR SUFFICIENT FOR ORGANIZED STORMS AND GOOD COLD POOL DEVELOPMENT...WHICH SHOULD LEAD TO A CONVECTIVE COMPLEX OR TWO MOVING THROUGH (OR AT LEAST ALONG THE EDGES) OF THE CWA. WHILE THE FORECAST IS EXTREMELY DEPENDENT ON THUNDERSTORM DEVELOPMENT AND PROPAGATION...THE GENERAL CONSENSUS OF THE HIGH-RES MODEL GUIDANCE /ESPECIALLY THE HRRR AND NAM-DNG)...AND EVEN THE LOWER-RES GFS AND ECMWF...SEEM TO BE ON A REASONABLE TRACK OF SHOWING A CLUSTER OF STORMS MOVING OVER FAR NRN LAKE SUPERIOR (CLOSER TO THE MAIN SHORTWAVE) AND ANOTHER MOVING ESE THROUGH THE U.P. PARALLEL TO THE CAPE GRADIENT. CONSIDERING EXPECTED STORM MODE BEING A CONVECTIVE COMPLEX AND AFOREMENTIONED INGREDIENTS...THINK THAT DAMAGING WIND IS THE GREATEST THREAT FROM ANY SEVERE STORMS...WITH THE SECONDARY THREAT GIVEN SHEAR AND INSTABILITY AND MAYBE A WEAK TORNADO IF ANY FAVORABLE BOUNDARY INTERACTIONS OCCUR. AGAIN...THE SEVERE THREAT IS VERY CONDITIONAL ON THE DEVELOPMENT AND EVOLUTION OF CONVECTION. ANY CONVECTIVE COMPLEXES SHOULD BE DECAYING AS THEY MOVE TO THE E...SHOULD SEVERE THREAT IS LOWER OVER THE ERN U.P. HIGH PRESSURE MOVING IN FROM THE W ON WED WILL LEAD TO CLEARING CONDITIONS...WITH HIGHS IN HE 60S AND 70S. .LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY) ISSUED AT 336 PM EDT TUE JUN 9 2015 FOG OVER THE GREAT LAKES WILL BE ON THE DIMINISHING TREND WEDNESDAY NIGHT AS THE SFC LOW ACROSS W QUEBEC EXITS E AND THE SFC TROUGH EXTENDING W THROUGH N LAKE SUPERIOR AT 00Z THURSDAY SLOWLY EDGES E. A RIDGE OF HIGH PRESSURE WILL BE BUILDING IN FROM THE NW WEDNESDAY NIGHT INTO THURSDAY. THIS AREA OF HIGH PRESSURE WILL REMAIN IN PLACE THROUGH SATURDAY MORNING. MEANWHILE...THE SFC LOW OVER KS AT 12Z THURSDAY WILL PUSH TO THE S WI/IN BORDER AT 18Z FRIDAY. THICK CLOUDS WILL PUSH OVER THE AREA...HELPING TO KEEP TEMPS FROM RISING MUCH PAST THE MID TO UPPER 60S /WITH EVEN SOME 50S RIGHT FROM THE TIP OF THE KEWEENAW PENINSULA E THROUGH WHITEFISH POINT/. THE POTENTIAL EXISTS FOR HEAVY RAIN OVER S CENTRAL UPPER MI DURING THE DAY FRIDAY...AT SOME POINT BETWEEN 09- 20Z. LOWER CONFIDENCE REMAINS...AS THE MODEL SOLUTIONS VARY BETWEEN NO PRECIP ACROSS THE CWA /12Z NAM/ TO THE ECMWF AND GFS WHICH HAVE OVER AN INCH OVER FAR S CENTRAL UPPER MI NEAR MNM. WILL CONTINUE WITH A MODEL BLENDED SOLUTION...WITH OVER HALF AN INCH OF RAIN POSSIBLE S OF A LINE FROM IMT TO ESC...AND OVER 1IN NEAR MNM. WITH DRIER E WINDS AT THE SFC MUCH OF LAKE SUPERIOR AND FAR N UPPER MI WILL REMAIN EITHER DRY OR WITH A WHOLE LOT LESS PRECIP. EXPECT A QUICK CUT OFF AS THE SFC LOW ELONGATES ACROSS LOWER MI AND THE LOWER GREAT LAKES FRIDAY INTO FRIDAY NIGHT. AS THE SYSTEM EXITS THE 500MB RIDGE OVER THE MID MS VALLEY WILL BUILD ACROSS THE UPPER GREAT LAKES FRIDAY NIGHT...AND LINGER THROUGH SATURDAY. EXPECT INCREASED SW FLOW ALOFT IN ADVANCE OF THE 500MB LOW OVER S CENTRAL CANADA SUNDAY MORNING. HOWEVER...AS THE LOW SHIFTS NE INTO HUDSON BAY MONDAY/MONDAY NIGHT IT WILL MAINLY MEAN ZONAL FLOW. WHILE THE CANADIAN IS MORE TO THE S AND QUICKER TO BRING THE SFC LOW/TROUGH OVER LAKE SUPERIOR SUNDAY AFTERNOON...THE SLOWER GFS/ECMWF SOLUTIONS LOOK MORE REASONABLE. WILL KEEP THE CWA RAIN FREE UNTIL THE DAYTIME HOURS SUNDAY. TS WILL BE POSSIBLE SUNDAY...ALTHOUGH THE 12Z GFS LOOKS TO HAVE SHIFTED THE BEST MOISTURE/STRONG THUNDERSTORM POTENTIAL TO OUR S. && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z WEDNESDAY NIGHT) ISSUED AT 152 AM EDT WED JUN 10 2015 SHOWERS AND TS IN ADVANCE OF APRCHG COLD FNT WILL IMPACT SAW EARLY IN THE TAF PERIOD. GUSTY WINDS MAIN THREAT. FOLLOWING THE COLD FROPA BY ABOUT 08Z AT SAW...A STEADY WNW WIND WL TURN GUSTY WITH DAYTIME HEATING ON WED. BEFORE DRIER AIR ARRIVES AND ALLOWS FOR VFR CONDITIONS TO PREDOMINATE ON WED...SOME UPSLOPE LO CLDS/MVFR OR EVEN IFR CONDITIONS MAY OCCUR AT IWD AND ESPECIALLY CMX. && .MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 348 PM EDT TUE JUN 9 2015 (FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE) WINDS WILL REMAIN 20 KNOTS OR LESS THROUGH THE FORECAST PERIOD. FOG WILL PERSIST ACROSS THE LAKE INTO WED AS A RELATIVELY MOIST AIRMASS MOVES OVER THE COLD GREAT LAKES WATER AND REMAINS OVER THE REGION. && .MQT WATCHES/WARNINGS/ADVISORIES... UPPER MICHIGAN...
