The episode as NWS MQT wrote it up.
Isolated severe thunderstorms developing along lake breeze boundaries produced large hail near Nisula and Alston in Houghton County on the evening of the 24th.
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 24, 6:48 PM EST, 1 hour 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 748 PM EDT WED JUN 24 2015 .SHORT TERM...(THIS EVENING THROUGH THURSDAY) ISSUED AT 400 PM EDT WED JUN 24 2015 SEVERAL SHORTWAVES WILL MOVE THROUGH THE UPPER GREAT LAKES REGION DURING THE NEXT 24-30HRS...BRINGING SOME SHOWERS AND A FEW THUNDERSTORMS TO THE AREA. THE FIRST SHORTWAVE IS MAKING ITS WAY ACROSS LAKE SUPERIOR AT THIS TIME...WITH THE WEAK COLD FRONT OVER UPPER MI COMBINING WITH THE LAKE SUPERIOR AND NOW LAKE MICHIGAN LAKE BREEZES TO PRODUCE SOME STRONGER TO SEVERE THUNDERSTORMS OVER S MARQUETTE COUNTY TO E DELTA COUNTY BY 20Z. THESE SHOWERS WILL CONTINUE TO MOVE TO THE EAST-SOUTHEAST OVER THE REST OF THE AFTERNOON HOURS...WITH ADDITIONAL SHOWERS NEARING FROM AROUND THE DLH AREA. THE SHOWERS WERE INITIALLY STRUGGLING TO DEVELOP TOO MUCH ...LIKELY DUE TO THE LIMITED INSTABILITY HELPED BY THE DRY LOW LEVEL AIR AND MIXING THAT OCCURRED EARLIER TODAY TO LOWER DEWPOINTS INTO THE UPPER 40S AND LOWER 50S. WHERE THE MIXING HAS BEEN LIMITED NEAR THE LAKE BREEZES...IS WHERE THE SHOWERS HAVE DEVELOPED. THIS SLIGHT INCREASE IN LOW LEVEL MOISTURE HAS PUSHED MLCAPE VALUES UP TO THE 500-600J/KG RANGE. EXPECTATION FOR THE REST OF THE DAY...EXPECT THESE SHOWERS TO DIMINISH AS DIURNAL HEATING IS LOST THIS EVENING AND THE SHOWERS PUSH TO THE SOUTHEAST. THE NEXT SHORTWAVE CURRENTLY MOVING INTO NORTHERN MINNESOTA WILL PUSH EAST ACROSS THE AREA TONIGHT. DIURNAL HEATING HAS HELPED THE SHOWERS AND THUNDERSTORMS REDEVELOP WITH THE WAVE AS IT MOVES THROUGH NORTHERN MINNESOTA /SHOWERS MENTIONED ABOVE NEAR DLH/. THIS WAVE WILL CONTINUE EAST ACROSS UPPER MICHIGAN TONIGHT AND EXPECT SCATTERED SHOWERS TO OCCUR ACROSS THE AREA. WITH THE STRENGTH OF THE WAVE AND MID LEVEL LAPSE RATES EXPECTED TO BE BETWEEN 6.5- 7C/KM...THINK THE POTENTIAL FOR THUNDER REMAINS AND WILL KEEP AT LEAST A SLIGHT CHANCE IN FOR MOST LOCATIONS. CAPE VALUES ARE PRETTY SKINNY AND ELEVATED...SO DON/T EXPECT ANYTHING SEVERE. THIS SHORTWAVE WILL DEPART THE EASTERN CWA ON THURSDAY MORNING WHILE A THIRD WAVE MOVES THROUGH THE AREA FROM THE NORTHWEST (CURRENTLY ENTERING CENTRAL SASKATCHEWAN). BETTER CHANCE FOR SHOWERS WILL BE OVER THE SOUTHEAST PART OF THE CWA IN THE MORNING WHEN THERE IS MORE MOISTURE IN PLACE. MODELS HAVE BEEN TRENDING FOR DRIER LOW LEVEL AIR MOVING INTO THE AREA TOMORROW AFTERNOON...SO THAT MAY END UP FORCING THE BETTER PRECIPITATION CHANCES FARTHER TO THE SOUTH AND MORE INTO THE SOUTH CENTRAL CWA. NORTHERLY FLOW HELPS PUSH THE LAKE BREEZE FARTHER INLAND AND IN TURN THE SHOWERS. .LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY) ISSUED AT 438 PM EDT WED JUN 24 2015 IT IS AN IMPRESSIVLY LIGHT WIND PATTERN THAT WE ARE IN WINDS BELOW 5KFT OFF THE GFS SOUNDINGS REMAIN BELOW 15KTS THROUGH THE DAY MONDAY. THIS AND THE FCST OF SHOWERS EVERY COUPLE OF DAYS OR SO WILL KEEP FIRE WX CONCERNS TO A MINIMUM. FRIDAY MAY OR MAY NOT HAVE SHOWERS. GIVEN HIGH PRESSURE OVER LAKE SUPERIOR AND E UPPER MI...THE INITIAL THROUGH WAS TO GO DRY. HOWEVER...I HAVE ADDED DIURNAL SHOWERS INLAND FROM THE LAKE BREEZES GIVEN OUR CURRENT PATTERN...AND FACT THAT MOST MODELS ARE PAINING OUT AT LEAST A FEW LIGHT SHOWERS WITH A 500MB TROUGH OVERHEAD. WILL KEEP TS CHANCES ONLY IN THE SLIGHT CHANCE RANGE. WAS IMPRESSED THAT EVEN THE 12Z ECMWF CAME IN WITH AT LEAST SOME QPF. AT THIS POINT FRIDAY NIGHT THROUGH SATURDAY LOOK DRY AS HIGH PRESSURE MOVES IN AT THE SFC AND ALOFT. A LOW MOVING ACROSS THE OHIO VALLEY AND CENTRAL APPALACHIANS WILL BE TOO FAR S TO DO TOO MUCH FOR OUR WX. EXPECT THE RETURN OF SHOWERS /AND SLIGHT CHANCE TS/ SATURDAY NIGHT INTO SUNDAY AS THE NEXT LOW AND 500MB TROUGH SLIDE IN FROM THE NW. THE BEST CHANCE OF PRECIP WILL LIKELY FALL OVER THE W HALF...BEFORE THE LOW SHIFTS TO THE E AND WIDS BECOME N OVER THE E HALF LATE SUNDAY NIGHT INTO MONDAY. AS FOR THE EXTENDED PORTION OF THE FCST...LITTLE TO NO CHANGES WERE MADE FROM A MODEL BLENDED SOLUTION. ADDITIONAL WAVES PUSHING IN FROM THE NW WILL KEEP MAINLY SLIGHT CHANCE POPS OFF AND ON THROUGH THIS PERIOD. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING) ISSUED AT 747 PM EDT WED JUN 24 2015 A DISTURBANCE MOVING E THRU MN WL BRING THE THREAT FOR SHOWERS AND PERHAPS A TS TO THE TAF SITES TNGT. SINCE THE DISTURBANCE WL BE MOVING INTO THE AREA DURING A PERIOD OF NOCTURNAL COOLING... CONFIDENCE IN TS OCCURRENCE IS TOO LO TO INCLUDE AN EXPLICIT MENTION IN THE TAFS. ALTHOUGH MVFR CONDITIONS/SOME FOG MAY OCCUR AT IWD AND ESPECIALLY SAW...LGT UPSLOPE E WIND INTO CMX IS LIKELY TO BRING A PERIOD OF IFR CONDITIONS TO THAT LOCATION DURING THE PERIOD OF OVERNGT COOLING. AFTER SUNRISE...EXPECT CONDITIONS TO IMPROVE TO VFR AT ALL 3 LOCATIONS. SOME MORE SHOWERS MAY IMPACT SAW INTO THE AFTN ON WED...BUT STABILIZATION OFF LK SUP AND SLOWLY BLDG HI PRES WL CAUSE VFR WX TO THE TAF SITES. && .MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 352 PM EDT WED JUN 24 2015 THERE WAS SOME LOW CLOUDS AND FOG OVER PORTIONS OF LAKE SUPERIOR THIS MORNING. SOME OF THAT HAS DISSIPATED AND THE NORTHERN PORTIONS HAVE BEEN COVERED BY CLOUDS. THUS...HAVE LIMITED CONFIDENCE ON COVERAGE AND THICKNESS. HIGH PRESSURE DROPPING SOUTH OVER LAKE SUPERIOR TONIGHT WILL LEAD TO WINDS STAYING BELOW 20KTS THROUGH AT LEAST SATURDAY. THEN A SERIES OF WEAK TROUGHS WILL DROP SOUTHEAST ACROSS LAKE SUPERIOR SUNDAY INTO EARLY NEXT WEEK...BUT WINDS ARE STILL EXPECTED TO STAY BELOW 20KTS. && .MQT WATCHES/WARNINGS/ADVISORIES...
