The episode as NWS MQT wrote it up.
A surface trough moving through a very warm and unstable air mass provided the focus for scattered severe thunderstorms over north central Upper Michigan during the early morning of the 26th.
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 Aug 26, 12:52 AM EST, 1 hour 6 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 152 AM EDT MON AUG 26 2013 .SHORT TERM...(THIS EVENING THROUGH MONDAY) ISSUED AT 420 PM EDT SUN AUG 25 2013 SHOWERS AND THUNDERSTORMS HAVE CONTINUED TO BE MAINLY CONFINED TO LAKE SUPERIOR...DESPITE THE SOUPY AIRMASS OVER THE LAND. MANY SITES HAVE REPORTED DEW POINTS IN THE 71-73F RANGE...WITH A COUPLE REPORTING 75F...AS TEMPERATURES JUMPED INTO THE LOW 90S. THE MAINLY ELEVATED STORMS OVER THE LAKE HAVE HAD A DIFFICULT TIME MOVING ONSHORE. GOOD MOISTURE TRANSPORT WILL REMAIN. DCAPE VALUES OF OVER 1K J/KG ARE OVER MUCH OF THE LAND AREAS /EXCLUDING THE KEWEENAW PENINSULA/...BUT THE CAPPED ENVIRONMENT HAS NOT BEEN ABLE TO PUSH MUCH UP OVER THE LAND. ONCE THE SLOWLY WEAKENING CAP DOES BREAK...CONVECTION WILL NEED TO BE MONITORED WITH THE QUICKLY GROWING TS. STRONG WINDS AND HAIL WILL BE THE MAIN THREATS...WITH FZ HEIGHTS HOVERING AROUND 15.6KFT AT 00Z. MLCAPES ARE EXPECTED TO DIMINISH FROM THE CURRENT READINGS NEAR 2K J/KG TO AROUND 1K J/K BY 03Z...AS THE BEST DYNAMICS SHIFT DOWN S OF THE WI BORDER. THE DAY1 SLIGHT RISK REMAINS OVER MUCH OF N WI AND INTERIOR W PORTIONS OF UPPER MI. CONVECTION THAT DOES FIRE LATER THIS AFTERNOON AND THIS EVENING WILL BE QUITE A BIT SLOWER FROM OUR MORNING/EARLY AFTERNOON VARIETY...SLOWING DOWN FROM THE 35-40KT SPEEDS TO AROUND 15-20KTS AS WINDS QUICKLY WEAKEN AT THE SFC AND ALOFT. DESPITE A COLD FRONT SINKING ACROSS THE AREA OVERNIGHT...THERE WILL BE ONLY SLIGHT RELIEF FROM THE HEAT AND HUMIDITY ON MONDAY...AS 850MB TEMPS RISE TO 20-22F. WITH A LESS FAVORABLE AND LIGHTER WIND /WITH LAKE BREEZES DEVELOPING OFF THE GREAT LAKES/ 90 DEGREE VALUES WILL LIKELY BE LIMITED TO INTERIOR W PORTIONS OF THE CWA. .LONG TERM...(MONDAY NIGHT THROUGH SUNDAY) ISSUED AT 426 PM EDT SUN AUG 25 2013 AS HAS BEEN THE CASE FOR SEVERAL DAYS...MEDIUM RANGE GUIDANCE REMAINS IN EXCELLENT AGREEMENT ON THE BIG PICTURE THIS WEEK. INITIALLY...TROFS WILL BE LOCATED ALONG OR JUST OFF THE W AND E COASTS WITH A STRONG MID/UPPER RIDGE DOMINATING A LARGE SWATH OF THE CONUS. RIDGE WILL BE ANCHORED BY AN ANTICYCLONE CENTERED OVER THE CNTRL PLAINS/MID MISSISSIPPI VALLEY. AS THE WEEK PROGRESSES...THE RIDGE WILL BE NUDGED SLIGHTLY WESTWARD AS SHORTWAVES ROUNDING THE RIDGE FORCE SLIGHT RETROGRESSION OF THE MEAN ERN TROF. LATE IN THE WEEK THRU THE EARLY PART OF NEXT WEEK...IT LOOKS LIKE A MORE PROGRESSIVE LARGE SCALE PATTERN MAY DEVELOP AS THE WRN TROF SHIFTS ACROSS THE NW CONUS INTO THE NRN PLAINS. FOR UPPER MI...THIS PATTERN WILL RESULT IN VERY WARM/HUMID/UNCOMFORTABLE CONDITIONS MOST DAYS OF THIS WEEK. THERE WILL BE TWO PERIODS WHEN HEAT/HUMIDITY WILL BE MOST UNCOMFORTABLE. THE FIRST IS OCCURRING NOW AND WILL CONTINUE FOR A COUPLE OF DAYS. THE SECOND WILL BE OVER THE UPCOMING WEEKEND AHEAD OF THE TROF PROGRESSING THRU THE NW CONUS. TEMPS WILL EXCEED 90F OVER PARTS OF THE FCST AREA DURING THE FIRST PERIOD AND POTENTIALLY DURING THE SECOND AS WELL. BTWN THE HOT PERIODS...THERE WILL BE SOME COOLING MIDWEEK AND SLIGHT EASING OF THE HUMID CONDITIONS...BUT TEMPS WILL REMAIN ABOVE NORMAL. THE PATTERN WILL ALSO BE FAIRLY ACTIVE FROM THE NRN PLAINS ACROSS THE UPPER LAKES TO THE NE STATES AS SHORTWAVES PERIODICALLY ROUNDING THE CNTRL RIDGE INTERACT WITH THE VERY WARM/HUMID/UNSTABLE AIR MASS IN PLACE...RESULTING IN EPISODES OF CONVECTION WITH POTENTIAL SEVERE WEATHER AND/OR HVY RAIN. TIMING/TRACKS OF SMALLER SCALE SHORTWAVES WHICH TYPICALLY ARE NOT RESOLVED WELL BY MEDIUM RANGE GUIDANCE WILL POSE THE BIGGEST CHALLENGE TO FORECASTING PCPN CHANCES...ESPECIALLY LATE IN THE WEEK. BEGINNING MON NIGHT/TUE...THIS CONTINUES TO BE A TIME PERIOD TO WATCH FOR POSSIBLE SVR STORMS AND/OR HVY RAINFALL. FEATURE OF INTEREST IS SHORTWAVE ENERGY PARTIALLY ASSOCIATED WITH FORMER TROPICAL STORM IVO IN THE ERN PACIFIC. IT WILL LIFT AROUND THE RIDGE AND THEN ACROSS THE UPPER LAKES. WHILE THERE HAS BEEN DISAGREEMENT ON THE LOCATION OF THE MAIN AXIS OF PCPN THAT THIS WAVE WILL GENERATE (POTENTIALLY MOSTLY S OR N OF UPPER MI)...IT GENERALLY APPEARED UPPER MI WOULD PROBABLY BE IN SOME PORTION OF THE CORRIDOR OF HEAVIER PCPN. NOW...BULK OF TODAYS MODEL GUIDANCE HAS DEFINITELY NARROWED IN ON BRINING THE MAIN AXIS OF PCPN ACROSS AT LEAST A GOOD PART OF UPPER MI. INITIALLY...LOCATION OF CONVECTION WILL BE INFLUENCED BY WHERE THE SFC BOUNDARY FROM MON IS LOCATED AS IT WILL SERVE AS A GOOD FOCAL POINT FOR CONVECTION MON NIGHT INTO EARLY TUE AS LOW-LEVEL JET OF 25-35KT IMPINGES ON IT. SINCE THAT BOUNDARY WILL MOST LIKELY DRIFT INTO FAR SRN UPPER MI/FAR NRN WI MON...INITIAL CONVECTION SHOULD DEVELOP ALONG OR PROBABLY JUST N OF BOUNDARY OVER FAR N NRN WI/ADJACENT UPPER MI ONCE LOW-LEVEL JET STRENGTHENS. IF SCENARIO UNFOLDS AS EXPECTED...THERE ARE SEVERAL FACTORS POINTING TOWARD A POSSIBLE HVY RAIN EVENT...INCLUDING HIGH FREEZING LEVELS AROUND 14KFT...850MB DWPTS OF 16-19C WITH PRONOUNCED THETA-E AXIS ORIENTED ALONG BOUNDARY...PRECIPITABLE WATER OF 200-250PCT OF NORMAL...AND LIKELIHOOD OF CONVECTION TRAINING ALONG/N OF BOUNDARY UNTIL SHORTWAVE PASSES. WILL RETAIN MUCH OF THE FLAVOR OF INHERITED FCST AND BRING INCREASING POPS DURING THE NIGHT ACROSS MUCH OF THE FCST AREA...ESPECIALLY THE S AND W PORTIONS AS STORMS DEVELOP/EXPAND IN A BAND N OF SFC BOUNDARY. MAIN COMPLEX OF SHRA/TSRA (POSSIBLE MCS) WILL LIKELY SLIDE ACROSS MOST IF NOT ALL OF UPPER MI AT SOME POINT FROM LATE MON NIGHT THRU AT LEAST EARLY TUE AFTN. WITH THE STRONGER SHORTWAVE PASSING TUE...DRY WEATHER STILL LOOKS LIKELY TO FOLLOW FOR WED AS WEAK SFC HIGH PRES SETTLES INTO THE UPPER LAKES BEHIND WAVE. LOW-LEVEL N TO NW BEHIND SYSTEM WILL BRING SLIGHTLY COOLER AIR INTO THE AREA WED...MORE NOTICEABLE NEAR LAKE SUPERIOR. TEMPS WILL BE STILL BE ABOVE NORMAL WITH 850MB TEMPS RUNNING 17-20C. EXPECT HIGHS IN THE 70S NEAR LAKE SUPERIOR TO THE MID 80S INLAND. DWPTS MAY NOT DROP SIGNIFICANTLY...SO IT WILL STILL FEEL SOMEWHAT UNCOMFORTABLE. AFTER A COUPLE OF PERIODS OF SHRA/TSRA ACROSS LAKE SUPERIOR...FOG MAY BE QUITE WIDESPREAD ACROSS THE LAKE BY TUE NIGHT. WITH N TO NW WINDS DEVELOPING TUE NIGHT/WED BEHIND WAVE AND AHEAD OF APPROACHING SFC HIGH...FOG WILL LIKELY SPREAD TO THE SHORELINE AREAS AND TRANSITION TO LOW STRATUS FARTHER INLAND FOR AT LEAST A PORTION OF WED MORNING. FOG MAY BE DENSE AT LOCATIONS NEAR THE LAKE TUE NIGHT INTO WED MORNING. WHETHER DRY WEATHER LINGERS INTO THU/FRI IS UNCERTAIN. OVER THE LAST FEW DAYS...THE GFS AND ECMWF HAVE BEEN STRUGGLING WITH SHORTWAVES ROUNDING THE RIDGE...WHICH IS EXPECTED THIS FAR OUT INTO THE MODEL RUNS. AT THIS POINT...BASED ON THE LAST SEVERAL RUNS OF BOTH MODELS...THERE ISN'T YET A PERIOD TO PICK OUT FOR INCLUDING ANYTHING MORE THAN SCHC POPS. TEMPS WILL REMAIN ABOVE NORMAL...WELL INTO THE 80S IN THE INTERIOR WITH SOME COOLING ALONG THE GREAT LAKES UNDER WEAK PRES GRADIENT. OVER THE UPCOMING WEEKEND...THE RIDGE WHICH WILL BE CENTERED OVER THE WRN PLAINS LATE WEEK WILL BEGIN TO GET SUPPRESSED AND PUSHED EASTWARD BY THE TROF MOVING INTO THE NW CONUS. DEEPENING AND STRENGTHENING SW FLOW AHEAD OF THE TROF WILL TRANSPORT OPPRESSIVE HOT AIR AND HIGH DWPTS BACK INTO THE AREA. STRENGTHENING LOW-LEVEL JET AND ONSET OF STRONGER WAA/MOISTURE ADVECTION ARGUES FOR SOME POTENTIAL FOR CONVECTION FRI NIGHT INTO SAT. THE ECWMF BRINGS A COLD FRONT INTO THE UPPER LAKES FOR SAT NIGHT/SUN IN ASSOCIATION WITH A SHORTWAVE MOVING ACROSS FAR NRN ONTARIO...SOMETHING IT HAS HINTED AT FOR SEVERAL RUNS. THE GFS HAS OCCASIONALLY HINTED AT THAT AS WELL. ONE FACTOR THAT MIGHT ARGUE FOR FRONT REMAINING N OF THE AREA IS THAT IF THE MODELS ARE CORRECT WITH THE LARGER SCALE TROF MOVING INTO THE NW CONUS...IT WOULD FORCE HIGHER HEIGHTS DOWNSTREAM INTO THE UPPER MISSISSISSI VALLEY/GREAT LAKES. IF A FRONT DOES DROP INTO THE AREA SUN...TEMPS...ESPECIALLY NEAR LAKE SUPERIOR WILL BE A LITTLE COOLER. THE BOUNDARY WOULD ALSO SERVE TO FOCUS SHRA/TSRA. && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z MONDAY NIGHT) ISSUED AT 148 AM EDT MON AUG 26 2013 -TSRA WILL IMPACT IWD AND CMX TO START...THEN COULD REACH SAW IN A FEW HOURS. YET TO BE SEEN STRENGTH OF TSRA BY TIME THEY REACH KSAW BUT BRIEF HEAVY RAIN AND GUSTY WINDS TO 30 KTS SEEM LIKELY. THE SFC TROUGH/VERY WEAK COLD FRONT CURRENTLY OVER WESTERN UPR MICHIGAN WILL SINK TO THE SE OF THE 3 SITES AROUND OR SHORTLY AFTER SUNRISE. IFR TO MVFR CONDITIONS HAVE FORMED AT IWD AS WINDS SHIFTED OFF LK SUPERIOR. COULD SEE SIMILAR SITUATION AT CMX WITH FOG/STRATUS DEVELOPING BEFORE SUNRISE. LAKE BREEZES WILL OCCUR AT ALL SITES THIS AFTERNOON. && .MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 349 PM EDT SUN AUG 25 2013 OUTSIDE OF ANY THUNDERSTORMS CROSSING LAKE SUPERIOR...THE TREND ON THE WINDS IS A DOWNWARD ONE...WITH GUSTS FALLING TO AROUND 20KTS OR LESS FROM LATE THIS AFTERNOON THROUGH THE ENTIRE GLF PERIOD. THE MAIN CONCERNS WILL BE STRONG THUNDERSTORMS INITIALLY...AND FOG THAT WILL BE DEVELOPING SHORTLY AND CONTINUE INTO WEDNESDAY. LOW PRESSURE NEAR JAMES BAY WILL WEAKEN SLIGHTLY ACROSS QUEBEC OVERNIGHT...DRAGGING A TROUGH ACROSS LAKE SUPERIOR. ANOTHER LOW STRETCHED FROM SOUTHERN CANADA THROUGH THE NORTHERN PLAINS MONDAY NIGHT WILL CROSS THE UPPER GREAT LAKES DURING THE DAY TUESDAY. EXPECT HIGH PRESSURE TO PUSH IN BEHIND THE LOW...AND REMAIN OVERHEAD THROUGH THURSDAY. AN ELONGATED TROUGH WILL THEN SINK SOUTHEASTWARD OVER THE UPPER GREAT LAKES THURSDAY NIGHT INTO FRIDAY. && .MQT WATCHES/WARNINGS/ADVISORIES... UPPER MICHIGAN... NONE. LAKE SUPERIOR... NONE.

The Marquette radar (KMQT), 34 km away, was scanning. The volume nearest the first event began at 06:59 UTC.
11 thunderstorm wind, 1 lightning. Local standard time, as filed.
Several large trees were reported down in the Van Riper State Park campground.
The observer east of Champion reported large trees and branches down.
A one-foot diameter pine tree was down across Wawonowin Club Road. The report was relayed via the local TV-6 station and was estimated from radar.
Numerous trees were reported down around Ishpeming...especially west and south of town. The report was relayed through TV-6 news and social media, and the time of the report was estimated from radar.
Isolated tree damage was reported around the area west of Ishpeming. Most of the tree damage occurred in the area near the intersection of Randall/Greenwood/Hollyhock Streets. The largest tree was a 10-12 inch diameter pine tree which was snapped near the base. The time of the report was estimated from radar.
Two trees roughly a foot in diameter fell near the intersection of CR 478 and Highway M-28 west of Ishpeming. One tree clipped the corner of a mobile home and another fell on a camper trailer and truck.
Forty-three trees were uprooted or snapped at Wawonowin Golf Course. Some trees were up to two feet in diameter and all fell in the same direction.
A lightning strike damaged electronics equipment in a neighborhood northeast of Negaunee.
A few trees uprooted or snapped and branches broken off in the South Angeline/Salisbury/Terrace Street area south of Ishpeming. One large branch fell on a car breaking the back window and doing additional body damage.
A large tree was knocked down at the intersection of Highway M-35 and County Road MP. Time of the report was estimated from radar.
Part of large tree fell onto Wright Street near Fitch Avenue in Marquette and narrowly missed a house.
The Luce County Emergency Manager reported trees down across northern Luce County. A tree fell on a tent at the Blind Sucker Campground and at Muskallonge State Park power lines were down as well. No injuries were reported.
