The episode as NWS APX wrote it up.
A potent line of thunderstorms developed over Lake Michigan, and moved across Northern Lower Michigan in the early overnight hours. These storms produced a considerable amount of wind damage, especially in Northwest Lower Michigan. There were a number of power outages, most widespread in the Cadillac area.
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 Gaylord, MI wrote its last area forecast discussion before the first event at Jun 7, 9:42 PM EST, 2 hours 8 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 1042 PM EDT THU JUN 7 2007 .UPDATE...DEEP LOW PRESSURE SYSTEM AND ASSOCIATED MID LEVEL WAVE MOVING QUICKLY INTO SRN ONTARIO THIS EVENING...COLD FRONT EXTENDING DOWN THROUGH NW WISCONSIN AS OF 02Z. DRYLINE OUT AHEAD OF THE FRONT ROUGHLY ACROSS NORTH CENTRAL WISCONSIN...AND SOME RENEWED CONVECTION ALONG THE DRYLINE HEADING NE TOWARD CENTRAL UPPER MICHIGAN. FURTHER SOUTH...SCT LINE OF CONVECTION ACROSS SE WISCONSIN INTO ILLINOIS ALONG LEADING EDGE OF MID LEVEL COOLING...HEADING NE TOWARD NRN LOWER MICHIGAN ATTM. 00Z APX SOUNDING TELLS THE STORY THUS FAR. MLCAPE RUNNING AROUND 600 J/KG...BUT A STRONG CAP IN PLACE JUST ABOVE 750 MB YIELDING NEARLY 170 J/KG OF CONVECTIVE INHIBITION. COMBINED WITH WEAK LOW LEVEL CONVERGENCE WELL AHEAD OF THE FRONT...EARLIER CONVECTION ACROSS WISCONSIN AS WELL AS THIN LINE OF SHOWERS/THUNDER THAT MOVED THROUGH NRN MICHIGAN PRETTY MUCH DWINDLED PRESSING INTO THE CAPPED ENVIRONMENT. SO UPSTREAM CONVECTION HAS NOT DEVELOPED THIS EVENING AS ANTICIPATED. HOWEVER...STILL IN A WAIT AND SEE MODE AT THIS JUNCTURE AS MID LEVEL COOLING PROCEEDS OVERNIGHT (ERODING THE CAP) AND UPSTREAM FRONT SWINGS INTO THE REGION LATE. ALTHOUGH WE ARE OBVIOUSLY PAST PEAK HEATING...STILL A DECENT MIXED LAYER AND STRONG WINDS ALOFT TO TAP INTO IF WE DO GET STORMS TO DEVELOP AND MOVE INTO THE REGION. BUT HAVE TONED DOWN THE SEVERE WEATHER THREAT IN THE HAZARDOUS WEATHER OUTLOOK/SPECIAL WEATHER STATEMENT BASED ON THE TRENDS AND WILL MAKE SOME POP ADJUSTMENTS TO THE GRIDS/ZONE FORECASTS. ADAM && .AVIATION...ISSUED AT 818 PM. STRONG LOW PRESSURE SYSTEM CENTERED NEAR DULUTH THIS EVENING WITH A COLD FRONT STRETCHING DOWN THROUGH NW WISCONSIN. WELL AHEAD OF THE FRONT...INITIAL LINE OF WDLY SCT SHOWERS/ISOLATED THUNDER WILL IMPACT THE PLN/APN TAF SITES THROUGH 01Z. SCT THUNDERSTORMS NOW OVER EASTERN WISCONSIN EXPECTED TO MOVE THROUGH NRN LOWER MICHIGAN AFTER 02Z AT TVC/PLN AND APN AFTER 04Z. HOWEVER...OVERALL EVOLUTION AND COVERAGE OF THUNDERSTORMS REMAIN IN QUESTION. BUT WITH STRONG WINDS PRESENT ALOFT ANY THUNDERSTORMS OVERNIGHT HAVE THE POTENTIAL OF PRODUCING VERY STRONG WINDS AT THE SURFACE AND LARGE HAIL. COLD FRONT PASSES THROUGH NRN LOWER MICHIGAN BETWEEN 12Z AND 16Z FRIDAY MORNING WITH A WIND SHIFT INTO THE NORTHWEST. THIS WILL BRING AN END TO THE SHOWER/THUNDERSTORM THREAT ACROSS NRN MICHIGAN...BUT FOLLOWED BY VFR CIGS FROM MIDDAY ONWARD AS COOLER AIR MOVES INTO THE REGION. ADAM && .PREV DISCUSSION...ISSUED AT 324 PM. ...SEVERE WEATHER EXPECTED TONIGHT... .DISCUSSION...981MB SURFACE LOW LIFTING INTO NORTHERN MN. AS FEARED...WARM FRONT HAS UTTERLY FAILED TO LIFT NORTHWARD THRU EASTERN UPPER MI...WITH SE WINDS AND COOL TEMPS IN THE ST MARYS VALLEY. TORNADO WATCHES ARE ALREADY UP UPSTREAM...AS DEEP CONVECTION HAS FIRED ALONG A COLD FRONT MARCHING ACROSS IOWA AND INTO WESTERN WI. CONVECTIVE TRENDS TONIGHT ARE THE CLEAR MAIN PROBLEM OF THE DAY. STILL-STRONG SYNOPTIC WINDS ARE A SECONDARY CONCERN. TONIGHT...IN SHORT...WEATHER STILL LOOKS NASTY TONIGHT. LOW CLOUD DECK IN WI IS OCCURRING IN THE AREA WITH THE HIGHEST LOW-LEVEL MOISTURE CONTENT...AND WHERE DEEP CONVECTION IS INHIBITED BY A CAP (THOUGH SOME CELLS HAVE FIRED IN NE WI). THE BACK EDGE OF THAT CLOUD DECK IS WHERE COLD ADVECTION AND ASCENT ALOFT IS RUPTURING THE CAP...THUS THAT IS WHERE STORMS ARE FIRING. EXTRAPOLATION AND MODEL PROGS AGREE THAT THIS CAP EROSION WILL ENTER NORTHERN/WESTERN PARTS OF THE FORECAST AREA AS SOON AS 03Z IN WESTERN CHIP/MACK...03Z TO 06Z THRU EASTERN UPPER AND ENTERING NW LOWER MI...AND LATER IN NE LOWER. THIS IS IN CONCURRENCE WITH EARLIER TIMING FORECASTS. CURRENT ACTIVITY IN NE WI DOES NOT APPEAR TO BE SURFACE BASED...AND SHOULD NOT DEVELOP INTO ANYTHING MAJOR GIVEN THE STRONG CAP IN PLACE HERE (IT IS NOT TAPPING AS MUCH INSTABILITY AS ACTIVITY FURTHER WEST). IF ANYTHING...INSTABILITY LOOKS TO BE GREATER THAN EARLIER PROGGED. SURFACE TEMPS IN THE MID/UPPER 70S...AND DEW POINTS IN THE LOWER 60S...SUPPORT ML CAPES AROUND 1K J/KG. THAT IS A CONSIDERABLE AMOUNT OF SURFACE BASED CAPE...ESPECIALLY FOR THE MIDDLE OF THE NIGHT. WHEN COMBINED WITH 50-60KT 850MB WINDS...AND 70KT 500MB WINDS (AND A NEAR 100KT JET UPSTREAM)...THE SET-UP IS EXCEPTIONALLY POTENT. THERE IS SIGNIFICANT MID-LEVEL DRY AIR UPSTREAM OF THE DEVELOPING UPSTREAM STORMS. THIS SHOULD ALLOW SIGNIFICANT COLD POOL PRODUCTION...AND PRODUCE A TRANSITION TO LINEAR MULTICELL CONVECTION WITH TIME. STORMS MAY MOVE THRU AS A SINGLE BIG LINE... OR IN MULTIPLE SMALLER LINE SEGMENTS. STRAIGHT LINE WINDS ARE THE MAIN CONCERN...AND COULD BE EXTENSIVE. ISOLATED TORNADOES ARE POSSIBLE...EITHER NON-SUPERCELLULAR WITH BOWING LINE SEGMENTS. THE POTENTIAL FOR EMBEDDED SUPERCELLS CANNOT BE IGNORED AS WELL...NOW THAT IT LOOKS MORE UNSTABLE THAN EARLIER PROGGED. THAT POTENTIAL WOULD BE HIGHER WITH MULTIPLE SMALLER LINE SEGMENTS...RATHER THAN ONE BIG LINE. SMALL ADJUSTMENTS TO TIMING OF PRECIP WILL BE MADE IN THE GRIDS... BUT BY AND LARGE THE THUNDER FORECAST WILL REMAIN UNCHANGED. WILL CARRY WIND ADVISORY THRU 8 PM. MULTIPLE REPORTS OF TREE DAMAGE RECEIVED FROM MANISTEE COUNTY...THOUGH GENERALLY OB SITES ARE STAYING SHORT OF CRITERIA. THAT SAID...A 42MPH GUST AT GLR IS RESPECTABLE. WINDS SHOULD SUBSIDE OVER LAND AFTER PEAK HEATING. FEEL REASONABLY COMFORTABLE IN KEEPING GALES ONLY WHERE COASTAL CONVERGENCE IS MOST FAVORABLE...WHICH IS SOUTH OF SLEEPING BEAR. ZOLTOWSKI FRIDAY...MODEL DATA IS IN GOOD AGREEMENT WITH THE STORM SYS MOVING OVR THE UPPER MIDWEST AND CENTRAL PLAINS. THE FRONT IS FCST TO BE ARND LAKE MICHIGAN/NW LWR MI BY 12Z FRIDAY. THE FRONT IS THEN FCST TO MOVE EAST OF LAKE HURON BTW 18Z AND 21Z FRI. THE AIRMASS IN ADVANCE OF THE FRONT WILL REMAIN MST AND UNSTABLE WITH 850 DEW PTS AROUND 14C...LIS AROUND ZERO...K INDEX OF 36C...CAPES NEAR 1400 J/KG AND 850 MB WINDS NEAR 35 MPH. WILL CONT WITH SHOWERS AND THUNDERSTORMS ALL ZONES IN THE MORNING IN ADVANCE OF THE FRONT. COULD SEE SOME LOCALLY HEAVY RAINFALL WITH 850 DEW PTS OF 14C AND A K INDEX NEAR 37C. HOWEVER STORMS SHOULD BE MOVING RATHER FAST WITH 850 MB WINDS TO 35 KNOTS...SO WILL LEAVE OUT MENTION OF HEAVY RAIN AT THIS POINT. WILL DROP MENTION OF THUNDERSTORMS OVER NORTHWEST LOWER IN THE AFTERNOON....BUT WILL KEEP THE MENTION OF AFTN THUNDERSTORMS ALONG THE LAKE HURON SHORELINE UNTIL FRONT PASSES EAST OF THE LAKE. WILL KEEP A SMALL CHANCE OF AFTN SHOWERS IN THE FORECAST FOR NORTHWEST LOWER AND EAST UPPER...AS LINGERING UPPER LEVEL CYCLONIC FLOW AND MSTR CONTS TO INFLUENCE THE UPPER LAKES. HIGH TEMPERATURES AND HOURLY TEMP TRENDS WILL BE TOUGH TO NAIL DOWN FOR FRIDAY. 850 MB TEMPS AHEAD OF THE FRONT WILL BE NEAR 16C FALLING TO 4C/5C OVER THE WESTERN LAKES BEHIND THE FRONT IN THE AFTERNOON. WILL KEEP NORTHEAST LOWER WARM THROUGH THE DAY...HOWEVER WILL MENTION TEMPS FALLING OR NEAR STEADY OVER NORTHWEST LOWER AND EAST UPPER MICHIGAN. FRIDAY NIGHT...NEARLY ZONAL FLOW ALOFT WILL COMBINE WITH AN AREA OF HIGH PRESSURE BUILDING BACK INTO THE REGION FROM THE SOUTH AND WEST. COOLER AND DRIER AIR WILL ALSO FILTER INTO THE REGION FRIDAY NIGHT. SOUNDING DATA AND MSTR PROGS SHOW 850/500 MB RH DROPPING TO AROUND 30 PCT. OVERALL WILL MENTION SKIES BECOMING PARTLY CLOUDY WITH DRY CONDITIONS. SATURDAY...SURFACE HIGH PRESSURE STRENGTHENS OVER THE GREAT LAKES... WHILE BECOMING CENTERED OVER THE STATE BY THE AFTERNOON. AT UPPER LEVELS...A 850 MB RIDGES BUILDS IN OVR THE REGION WITH NEARLY ZONAL FLOW AT 500/700 MB. MODEL SOUNDING DATA AND MSTR PROGS AGAIN SHOWING DRY CONDS TO LINGER OVER THE REGION...AS 850/500 MB RH DRYS A LITTLE MORE TO 25 PCT. MODEL SOUNDINGS SHOW MIXING THROUGH 850 MB...WHILE 850 MB TEMPS ARE PROGGED TO BE AROUND 8C/9C. OVERALL WILL MENTION AFTN HIGHS IN THE MID 70S WITH MOSTLY SUNNY SKIES. SATURDAY NIGHT WILL LEAVE DRY AS SURFACE HIGH PRES REMAINS CENTERED OVER THE GREAT LAKES. ADDITIONAL SUBSIDENCE WILL BE GENERATED BY AN UPPER LVL RIDGE BUILDING OVER THE STATE THROUGH THE EVENING. SUNDAY THROUGH THURSDAY... HIGH PRESSURE WILL DOMINATE THE FORECAST SUNDAY THROUGH WEDNESDAY... AS THE AREA OF HIGH PRESSURE THAT WAS CENTERED OVER THE STATE SUNDAY...ROTATES SLOWLY TOWARD THE EAST COAST AND BECOMES ELONGATED ALONG THE MID ATLANTIC SEABOARD FOR THE BEGINNING OF THE UP COMING WORK WEEK. CORRESPONDING UPPER LEVEL PATTERNS SUGGEST...RIDGING TO BEGIN BUILDING INTO THE GREAT LAKES SUNDAY AND STRENGTHENING THROUGH THE UP COMING WORKWEEK. THE UPPER RIDGING PATTERN REACHES FULL STRENGTH OVER THE REGION TUESDAY AND WEDNESDAY IN ADVANCE OF A DEVELOPING STORM SYSTEM OVR THE CENTRAL PLAINS/UPPER MIDWEST. 850 MB TEMPS CONTINUALLY WARM OVER THE GREAT LAKES THROUGH THE PERIOD IN RESPONSE TO THE STRENGTHENING UPPER LEVEL RIDGING PATTERN. 850 MB TEMPS WARM FROM 11C MONDAY TO NEAR 16C TUESDAY NIGHT AND WEDNESDAY. THEREFORE WILL SLOWLY WARM TEMPS FROM THE MID 70S SUNDAY TO THE LOW AND MID 80S WED. WILL KEEP THURSDAY DRY FOR NOW...EVEN WITH THE DEVELOPING CENTRAL PLAINS/UPPER MIDWEST STORM SYSTEM PUSHING TWD THE WRN LAKES. THE STRENGTH OF THE SURFACE AND UPPER LEVEL RIDGING PATTERNS SHOULD KEEP THAT SYSTEM AT BAY UNTIL FRIDAY/SATURDAY. SWR && .APX WATCHES/WARNINGS/ADVISORIES...GALE WARNING LMZ345 THRU TONIGHT. &&
