The episode as NWS DTX wrote it up.
A thunderstorm moving into Southern Lake Huron produced a measured 42 mph thunderstorm wind gust.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
318 PM EDT SAT SEP 3 2011
.SHORT TERM...THIS AFTERNOON AND TONIGHT
LATEST UPPER AIR/WATER VAPOR ANALYSIS SHOWING THE MAIN AMPLIFYING
MID LEVEL WAVE DIGGING ACROSS THE NORTHERN PLAINS...WHILE A LEAD
SHORTWAVE EMERGES EASTWARD WITHIN THE EXPANDING DOWNSTREAM HEIGHT
FALL REGION ACROSS IOWA. SUSTAINED AREA OF CONVECTION ANCHORED
ALONG AN OLD GUST FRONT CONTINUES TO SLIDE ACROSS NORTHERN
IL...WHILE MORE SPOTTY DEVELOPMENT LINKS TO THE THETA-E RIDGE
EXTENDING FROM SOUTHERN LAKE MICHIGAN INTO THE SAGINAW VALLEY/
THUMB. WELL ESTABLISHED MID LEVEL CAPPING MAINTAINING A VIRTUALLY
CLOUD FREE ENVIRONMENT TO THE SOUTHEAST OF THIS AXIS...WITH THE FULL
INSOLATION YIELDING HIGHS INTO THE LOW/MID 90S FROM THE NORTHERN
DETROIT SUBURBS SOUTHWARD.
STRONG MID LEVEL ASCENT/HEIGHT FALLS WILL RAPIDLY EXPAND EASTWARD
THROUGH THE NIGHT WHILE DRIVING THE ASSOCIATED COLD FRONT INTO THE
LOWER PENINSULA. THE SOUTHERN FLANK OF THIS FORCING FIELD WILL
RESIDE WITHIN FAVORABLE EXIT REGION JET DYNAMICS CARRYING 30-40
KNOTS OF DEEP LAYER SHEAR. STRONG HEATING IN ADVANCE OF THIS
FORCING...WHERE MUCAPE VALUES SIT AT 3 KJ/KG AND 0-1KM MLCAPE COULD
APPROACH 2 KJ/KG...WILL PROVIDE A THERMODYNAMIC ENVIRONMENT
CONDUCIVE FOR ORGANIZED DEVELOPMENT AND UPSCALE GROWTH OF CONVECTION
AS THE CAP BEGINS TO WEAKEN FROM NORTHERN IL INTO SOUTHEAST MI
THROUGH THE LATE EVENING AND EARLY OVERNIGHT HOURS /00Z-06Z/. LOWER
END POTENTIAL DOES EXIST FOR CONVECTION TO BUST THE CAP AND INITIATE
LOCALLY WITHIN THE 21-00Z WINDOW SOUTH OF M-59...GIVEN THE STRONGER
THERMAL RESPONSE TO THE FULL INSOLATION SEEN IN THIS CORRIDOR AND
THE PRESENCE OF A SHALLOW/REMNANT OUTFLOW LEFT BEHIND FROM THE
MORNING MCS TO THE NORTH.
ANY LEAD CONVECTION ARRIVING FROM THE WEST WILL CARRY A SEVERE
HAIL/WIND THREAT GIVEN THE DEGREE OF INSTABILITY AND JUST ENOUGH
UNIDIRECTIONAL/DEEP LAYER SHEAR IN PLACE. IN ADDITION...POTENTIAL
FOR A LOWER LEVEL FGEN RESPONSE IN THE PRESENCE OF GOOD UPPER JET
DYNAMICS AND ELEVATED PW VALUES /1.75"/ MAY RESULT IN HEAVY RAINFALL
OVERNIGHT. THIS SETUP CONTINUES TO SUPPORT LIKELY POPS THROUGHOUT
THE TONIGHT PERIOD.
&&
.LONG TERM...SUNDAY THROUGH SATURDAY
LOW LEVEL FRONTOGENESIS AND A NARROW BAND DEFORMATION FLOW WILL
FAVOR SHOWERS CONTINUING INTO SUNDAY MORNING FOR MUCH OF THE
FORECAST AREA BEFORE THE DRY SLOT SWINGS THROUGH IN THE EARLY
AFTERNOON. MONDAY THROUGH TUESDAY NIGHT CONTINUE TO BE A LITTLE
PROBLEMATIC TEMPERATURE-WISE AS THE REMNANTS OF TS LEE ARE PULLED
NORTHWARD. THE 12Z MODEL SUITE MAINTAINS THAT SE MI WILL BE EMBEDDED
WITHIN A N-S PRESSURE GRADIENT RESULTING IN MORE EFFICIENT COLD
ADVECTION LATE SUNDAY INTO MONDAY. THE GFS HAS TRENDED COOLER...THE
NAM MARKEDLY SO. HOWEVER... NAM CONTINUES TO BE AN OUTLIER IN MANY
REGARDS AS IT HAS FOR MUCH OF THE WEEK. THE GFS/ECMWF ARE THE
PREFERRED GUIDANCE FOR THE BALANCE OF THE LONG TERM PERIOD.
MONDAY THROUGH TUESDAY NIGHT...850MB TEMPS ON MONDAY WILL FALL INTO
THE LOW TO MID SINGLE DIGITS. THE 12Z MAV GUIDANCE IS ABOUT 8F
COOLER ACROSS THE NORTH AND 4-5F COOLER ACROSS THE SOUTH COMPARED TO
ITS PREVIOUS RUN...PRESUMABLY THE RESULT OF AN UPDATED SOLUTION FOR
THE HANDLING OF TS LEE. AM STILL NOT READY TO JUMP THE GUN ON HAVING
THE ENTIRE CWA FAIL TO REACH 65F FOR A HIGH ON MONDAY...BUT
CONFIDENCE IN SOMETHING A TOUCH COOLER THAN THE INHERITED FORECAST
IS INCREASED...SO WILL BLEND MONDAY'S FORECAST HIGHS WITH THE LATEST
MAV TO GIVE THEM A SLIGHT NUDGE DOWNWARD. SHOWERS WILL ALSO BE A
FAIRLY GOOD BET ON MONDAY BUT MAINLY OVER THE WATER WHERE
INSTABILITY WILL BE GREATER. OVER LAND...WE WILL AT LEAST SEE A
ROBUST CU DECK WITH THE POTENTIAL FOR DIURNAL SHOWER ACTIVITY BY
AFTERNOON AS 0-3KM LAPSE RATES STEEPEN. SLIGHT TEMPERATURE
MODERATION CAN BE EXPECTED INTO TUESDAY.
FOR WEDNESDAY AND BEYOND...CONTINUED MINOR HEADACHES RELATED TO
TROPICAL WX. THE GFS HAS TRENDED STRONGLY TOWARD THE ECMWF IN
DEPICTING WHAT THE WRF GLOBAL HAS SHOWN FOR DAYS NOW...AND THAT IS
PART OF TS LEE BEING SHEARED AWAY AS IT IS LIFTED NORTHWARD BY THE
UPPER TROUGH WHILE THE BULK OF THE CIRCULATION IS LEFT BEHIND OVER
THE OHIO VALLEY AND IS CUTOFF FROM THE MEAN FLOW. ASSUMING THIS
SOLUTION TO BE A VALID ONE...AND IF THE PREFERRED GUIDANCE IS ANY
INDICATION...THE END OF THE WEEK MAY FEATURE A ZONALLY ORIENTED
RIDGE AXIS EXTENDING ACROSS THE NORTHERN LAKES WITH THE RESULTANT
PRESSURE GRADIENT ADVECTING THE LEE'S REMNANTS WESTWARD ACROSS THE
SOUTHERN LAKES OR OHIO VALLEY...BUT NOT READY TO INTRODUCE POPS ATTM.
&&
.MARINE...
A WEAK GRADIENT WILL MAINTAIN LIGHT WINDS ACROSS THE LAKES THROUGH
TONIGHT. DEEPENING LOW PRESSURE TRACKING ACROSS UPPER MICHIGAN
TONIGHT WILL SEND A COLD FRONT THROUGH THE REGION EARLY SUNDAY.
NORTHWESTERLY WINDS WILL INCREASE SUNDAY INTO MONDAY BEHIND THIS
FRONT AS COOLER AIR ADVANCES INTO THE REGION. THIS MAY LEAD TO SMALL
CRAFT ADVISORY CONDITIONS ON MONDAY. CONDITIONS WILL ALSO BECOME
FAVORABLE FOR WATERSPOUT DEVELOPMENT DURING THIS TIME.
&&
.AVIATION...ISSUED 150 PM EDT SAT SEP 3 2011
//DISCUSSION...
GOOD AVIATION CONDITIONS WILL EXIST THROUGH THE REMAINDER OF
AFTERNOON PERIOD AS WARM MID LEVEL TEMPERATURES REMAIN SUFFICIENT
IN LIMITING DIURNAL CUMULUS GROWTH AND SUPPRESSING THUNDERSTORM
DEVELOPMENT. EXCEPTION WILL BE AT MBS...WHERE PERSISTENT
CONVERGENCE WILL CONTINUE TO GENERATE SCATTERED CONVECTION THROUGH
19-20Z. THE CHANCE OF THUNDERSTORMS WILL INCREASE ACROSS THE
REMAINDER OF SOUTHEAST MICHIGAN DURING THE EVENING AND OVERNIGHT
HOURS IN ADVANCE OF AN APPROACHING COLD FRONT. THE POTENTIAL
EXISTS FOR A MORE ORGANIZED COMPLEX OF THUNDERSTORMS TO IMPACT A
PORTION OF THE REGION DURING THIS TIME. THIS OPPORTUNITY WILL LIKELY
EVOLVE FROM ORGANIZING CONVECTION UPSTREAM AND STILL CARRIES A
MODERATE DEGREE OF UNCERTAINTY IN BOTH THE EVENTUAL TRACK AND
OVERALL COVERAGE. WILL GO AHEAD AND HIGHLIGHT THE MOST LIKELY
PERIOD FOR THUNDERSTORMS /00Z-04Z/ WITH A TEMPO. SHOWERS WITH
EMBEDDED THUNDERSTORMS WILL INCREASE IN COVERAGE OVERNIGHT AS
STRONGER MID LEVEL FORCING ARRIVES. THIS WILL PROVIDE A PERIOD OF
MVFR CONDITIONS IN PREVAILING SHOWERS THROUGH THE EARLY MORNING
HOURS.
FOR DTW...THE ATMOSPHERE OVER METRO DETROIT WILL LIKELY REMAIN
CAPPED THROUGH THE AFTERNOON...THUS INHIBITING THUNDERSTORM
DEVELOPMENT. INCREASING INSTABILITY LATER IN THE DAY ALONG WITH THE
POTENTIAL FOR THUNDERSTORMS TO TRACK IN FROM THE WEST WILL INCREASE
THE CHANCES FOR THUNDERSTORMS AFTER 23Z.
//DTW THRESHOLD THREATS...
* MEDIUM CONFIDENCE ON THUNDERSTORM POTENTIAL BUT LOW CONFIDENCE ON
TIMING THIS EVENING AND TONIGHT.
