The episode as NWS MQT wrote it up.
Severe thunderstorms produced strong and damaging wind over western Lake Superior on the 7th.
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 7, 6:25 PM EST, 1 hour 22 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 725 PM EDT THU JUN 7 2007 .DISCUSSION (ISSUED AT 450 PM EDT)... SHORT TERM (TONIGHT)... FOCUS SQUARELY ON THUNDERSTORMS AND SEVERE WEATHER POTENTIAL. 50KT H85 WINDS...H5 WINDS OF 100KT YIELD 0-6KM SHEAR OF 60-70KT AND SWIFT STORM MOTIONS OF 23050KT. ML CAPES 1000-1500J/KG POKING INTO SW CWA WITH T/TD IN UPR 70S AND TD INTO MID 60S. THUS FAR...ONLY ISOLD CELLS FARTHER EAST OVR ECNTRL WI...BUT OTHERWISE...CLUSTERS OF STORMS ALONG DRY LINE MOVING INTO SE MN...ARE THE MAIN ISSUE SO FAR. NUMEROUS REPORTS OF WIND DAMAGE WITH THESE CELLS...WHICH ARE PROJECTED INTO SW CWA WITHIN NEXT 3 HOURS. STILL UNCERTAIN HOW INSTABILITY GRADIENT OVR CWA WILL PLAY OUT THIS EVENING. FOLLOWING THE DRY LINE ACROSS CWA...THREAT OF STRONG STORMS WILL END BTWN 03Z-06Z. 0-1KM/0-3KM STORM RELATIVE HELICITY VALUES AND WARM FRONT ACROSS UPR MI WILL KEEP POSSIBILITY OF TORNADOES THIS EVENING. STRONG SHEAR AND SUFFICIENT INSTABILITY ALLOW SUPERCELL STRUCTURE WITH ANY DEVELOPING STORMS LEADING TO POTENTIAL LARGE HAIL AND DAMAGING WINDS. OVERALL...NOT A SITUATION TO MESS WITH. CELLS ARE UPSTREAM AND ARE PRODUCING DAMAGING WINDS...AT THE LEAST. SYNOPTIC WINDS NOT AS STRONG...EXCEPT IN THE EAST WHERE SUNSHINE PREVAILS. STILL...KEPT WIND ADVY THIS EVENING UNTIL STRONG FRONT BLOWS THROUGH. IT WILL NOT TAKE MUCH TO PRODUCE NON-THUNDERSTORM ADVY GUSTS WITH 30-40KT JUST OFF THE SURFACE. LONG TERM...(FRI THROUGH THU) FRI...EVEN WITH STRONG DRY ADVECTION AND 850 MB CAA IN THE MORNING...MODERATE 700-300 QVECTOR CONV WITH THE MID LEVEL TROUGH WILL STILL SUPPORT LOWER END CHANCE POPS FOR -SHRA...ESPECIALLY OVER THE NW CWA. SUNSHINE AND INCREASED MIXING BY AFTERNOON SHOULD ALSO LEAD TO GUSTY WEST WINDS WITH SOME GUSTS TO NEAR 40 MPH OVER THE KEWEENAW GIVEN FAVORABLE TERRAIN ORIENTATION AND NAM 1K-2K FT WINDS FCST AROUND 35 KT. STRONG QVECTOR DIV MOVING IN DURING THE AFTERNOON SHOULD BRING CLEARING SKIES FROM WEST TO EAST. FRI NIGHT INTO SUN...A MORE ZONAL PATTERN DEVELOPS WITH THE POTENTIAL FOR FAST WEAK SHORTWAVES MOVING THROUGH THE UPPER GREAT LAKES. HIGH PRES WITH DRY AIR IS EXPECTED TO GIVE WAY TO WAA AND MOISTURE RETURN BY SUN. EVEN WITH THE 850 MB THETA-E RDG POKING INTO THE WRN LAKES...PER 12Z GFS...SINCE THE FRONTAL BNDRY REMAINS OVER N OF LK SUPERIOR AND GFS MOISTURE/INSTABILITY SEEMS A BIT OVERDONE...SHRA/TSRA WERE NOT ADDED AT THIS POINT. MON THROUGH THU...MODELS ARE IN GOOD AGREEMENT WITH PATTERN AMPLIFICATION PUSHING A RDG INTO THE WRN AND CNTRL GREAT LAKES. THE GFS WAS A BIT MORE PROGRESSIVE COMPARED TO THE PREFERRED ECMWF/UKMET AND GFS ENS MEAN. CONSIDERABLE ENSEMBLE SPREAD HOWEVER AND PROXIMITY OF THE DEEPER MOISTURE AXIS TO WRN LK SUPERIOR PER ECMWF...WARRANTS AT LEAST LOWER END POPS ESPECIALLY OVER THE WEST BY WED/THU. && .MARINE...LOW PRES OF 29.0 INCHES OVER SW ONTARIO LATE THIS EVENING WILL DRAG A COLD FRONT ACROSS LAKE SUPERIOR OVERNIGHT AND EARLY FRI MORNING. SE WINDS GOING W IS WAY WINDS GO NEXT 24 HOURS. STRONG WIND FIELDS JUST OFF LK SURFACE...SO NEED TO CONTINUE POTENTIAL GALES UNTIL LOW PASSES TO NORTH ON FRI. ALREADY SEEING LOCAL CONVERGENCE EFFECTS PRODUCING GUSTS TO 45 KT. HIGH PRES BECOMES ESTABLISHED AFTER THAT WILL LEAD TO LIGHTER WINDS AND KEEP WINDS LESS THAN 30 KT THE REST OF THE FORECAST PERIOD. && .AVIATION...FOR THE 00Z TAFS... AT TAF ISSUANCE TIME...LOOKS LIKE CLUSTER OF TS OVER WRN LK SUP WL MISS CMX TO THE W...AND CLUSTER OF TS OVER NE WI WL MISS SAW TO THE SE. HOWEVER...THREAT OF ISOLD TS WL PERSIST UNTIL LATE EVNG WHEN DRY SURGE TO THE SE OF POWERHOUSE LO PRES MOVING NE THRU MN INTO NW ONTARIO OVERWHELMS ANY LINGERING CNVCTN. GUSTY WINDS NOTED WITHIN THIS DRY SLOT...BUT LOSS OF DIURNAL HTG/SFC STABILIZATION WL PROBABLY ENSURE WINDS OBSVD AT SAW/CMX ARE NOT AS GUSTY AS OBSVD THIS AFTN TO THE SW. PASSAGE OF SFC TROF LATE TNGT WL CAUSE A PD OF GUSTY W WINDS AND MVFR CIGS/-SHRA ESPECIALLY OVER THE UPSLOPE TERRAIN AT CMX INTO TMRW MRNG. BUT ARRIVAL OF DRIER AIR IN THE AFTN FOLLOWING THIS TROF WL ALLOW FOR CLRG. BUT GUSTY W WINDS WL PERSIST ESPECIALLY AT CMX. && .MQT WATCHES/WARNINGS/ADVISORIES...
