The radar
The Detroit radar (KDTX), 77 km from the middle of the area, began a volume at 23:03 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Detroit, MI (KDTX), launched 12:00Z, 11.1 hours before the alert went out and 80 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
344 PM EDT SUN OCT 14 2012
.SHORT TERM... THIS AFTERNOON THROUGH TONIGHT
COVERAGE OF SHOWERS AND THUNDERSTORMS, RESPONDING TO AFTERNOON
BOUNDARY LAYER DESTABILIZATION OVER WESTERN LOWER MICHIGAN DOWN INTO
NORTHERN INDIANA, WILL SPREAD INTO OUR AREA DURING THE LATE
AFTERNOON. SATELLITE IMAGERY AND SURFACE OBSERVATIONS INDICATE A
COMBINATION SURFACE HEATING PERMITTED BY AND MID LEVEL
DESTABILIZATION DUE TO THE DRY SLOT IS HELPING WITH SURFACE BASED
INSTABILITY. HOURLY MESOANALYSIS INDICATES SURFACE BASED CAPE
PUSHING ABOVE 500 J/KG IN SOUTHWEST LOWER MICHIGAN, THE LEVEL OF
INSTABILITY THAT SEEMS REQUIRED SO FAR TODAY FOR CONVECTION STRONG
ENOUGH TO BECOME ORGANIZED. CAPE IN THE 500 J/KG+ RANGE WILL MAKE
UPDRAFTS STRONG ENOUGH TO WITHSTAND THE STRONG LOW LEVEL WIND SHEAR
THAT WILL OTHERWISE CUT DOWN ANY STORMS OR RESULT IN LINES PARALLEL
TO THE SHEAR VECTOR. THE LOW TO MID LEVEL SHEAR PROFILE DOES
SUPPORT MINI SUPERCELL MODES OF CONVECTION EVOLVING INTO LINE
SEGMENTS WITH TIME AS MOST OF THE CAPE IS IN THE 0-3KM LAYER.
DAMAGING WIND WILL BE THE MAIN CONCERN FOR SEVERE WEATHER WITH WIND
SPEED AVERAGING 55 KNOTS IN THE 850 TO 700 MB LAYER IN THE WARM
SECTOR.
SEVERE WEATHER POTENTIAL WILL LINGER THROUGH THE EVENING BEFORE
DIMINISHING DUE TO THE LOSS OF INSTABILITY OR DUE TO THE COLD FRONT
JUST DRIVING ACTIVITY EASTWARD OUT OF THE AREA. THE COLD FRONT IS
SET TO PRESENT ITS OWN PROBLEMS AS IT LOOKS CAPABLE OF STRONG WIND
GUSTS BOTH ALONG AND IN THE COLDER AIR BEHIND THROUGH THE OVERNIGHT
HOURS. MATCHING UPSTREAM OBSERVATIONS WITH THE EVOLUTION OF THE
SURFACE PRESSURE FIELD MAKES BELIEVABLE MODEL DEPICTIONS OF A STRONG
DYNAMIC COMPONENT TO THE WIND SPEED ASSOCIATED WITH THE FRONT. THE
NAM OFFERS A 6-8 MB 3 HR PRESSURE RISE FOR A RESPECTABLE ISALLOBARIC
POP BEHIND THE FRONT. THIS ALONG WITH THE WELL MIXED BOUNDARY LAYER,
STRONG LOW LEVEL COLD ADVECTION, AND RESULTING LOW LEVEL SUBSIDENCE
INDICATED IN MODEL CROSS SECTIONS WILL BE A GOOD ENVIRONMENT FOR
WIND GUST TO 40 MPH. NO WIND HEADLINES OVER LAND AREAS BUT THIS WILL
BE MONITORED AS THE NIGHT PROGRESSES.
&&
.LONG TERM...MONDAY THROUGH NEXT WEEKEND
FAIRLY ACTIVE TRANSITIONAL FALL PATTERN LOOKS TO CONTINUE THROUGH
THE WEEKEND. THE CURRENT LOW PRESSURE SYSTEM WILL EXIT EASTWARD ON
MONDAY. A WEAKER SHORTWAVE WILL TRACK ACROSS THE NORTHERN LAKES ON
TUESDAY NIGHT WITH PRECIP BLEEDING SOUTHWARD INTO SE MI. THEN ON
THURSDAY A LARGE UPPER LOW WILL TRACK OVER THE GREAT LAKES REGION
BECOMING A SLOW MOVING CUTOFF LOW. THIS WILL LIKELY PRODUCE SEVERAL
ROUNDS OF SHOWERS THROUGH THE WEEKEND AS SEVERAL VORTICITY LOBES
ROTATE AROUND THE LOW.
THE SFC LOW CURRENTLY OVER THE CENTRAL GREAT LAKES WILL MOVE OVER SE
ONTARIO BY MONDAY MORNING WHICH WILL DRAG THE TRAILING DEFORMATION
ZONE THROUGH CENTRAL MI. WITH SUCH A STRONG LLJ IN THE WARM SECTOR
PRODUCING A VERY EFFICIENT MOIST CONVEYOR BELT OVER THE WARM FRONT
FEEDING INTO THE DEFORMATION ZONE. IN ADDITION...THE MID LEVEL
TROUGH AXIS WILL BE SLIDING OVER THE AREA AS WELL ADDING SOME BROAD
UPPER LEVEL SUPPORT TO THE SHOWERS. THE TROUGH WILL BECOME
NEGATIVELY TILTED AS A VORT MAX SHOOTS INTO THE TROUGH. THIS WILL
ALSO CAUSE THE TROUGH TO SLOW ITS EASTWARD PROGRESS. ALL THIS SHOULD
RESULT IN RAIN SHOWERS EARLY...GRADUALLY TAPERING OFF INTO THE
AFTERNOON. LOCATIONS TO THE NORTH WILL HAVE A BETTER CHANCE OF
GETTING THESE SHOWERS AS THE FORCING HAS...AND WILL CONTINUE TO
BE...STRONGER ACROSS MID MI.
TUESDAY AND WEDNESDAY WILL BE FAIRLY QUIET DAYS WITH SOME LOW END
POPS ONCE AGAIN CENTERED MORE ACROSS NORTHERN LOWER MI. THE LONG
WAVE PATTERN FLATTENS OUT TO A WEAKLY NW FLOW PATTERN WITH A LOW
AMPLITUDE SHORTWAVE EMBEDDED WITHIN. THE SHORTWAVE WILL TRACK ACROSS
NORTHERN MI AND THE U.P. BUT CANNOT RULE OUT SOME LIGHT SHOWERS OVER
THE AREA AS THE WARM FRONT LIFTS UP INTO THE WESTERN LAKES.
SOUTHERLY FLOW WILL AGAIN DEVELOP TUESDAY ALLOWING WAA ADVECTION AND
MOISTURE TRANSPORT AIDING THE SHOWER DEVELOPMENT. THE WAA WILL LEAD
TO TEMPS ONCE AGAIN INCREASING TO NEAR 70F ON WED.
NOTABLE CHANGES THEN OCCUR IN THE LONGWAVE PATTERN AS MODELS SHOW A
+140 KNOT JET STREAK ENTERING THE PACIFIC NW WHICH WILL CARVE A
LARGE UPPER LEVEL TROUGH OVER THE CENTRAL PLAINS. THIS LARGE TROUGH
WILL DEEPEN AS IT TRACKS OVER THE GREAT LAKES THURSDAY AND INTO THE
WEEKEND. EARLY MODEL RUNS ALL SHOWED THIS BECOMING A CUTOFF LOW
WHICH WOULD HANG OVER THE GREAT LAKES THROUGH THE WEEKEND. CURRENT
RUNS ARE SUGGESTING IT WILL CUT OFF BUT NOT BECOME SO FAR REMOVED
FOR THE UPPER LEVEL JET THAT IT STALLS OUT...THUS MAY EXIT BY
SUNDAY. A LITTLE EARLY TO HANG YOUR HAT ON ANY MODEL TO MODEL
CHANGES SO WILL CONTINUE LOW CHANCE POPS THROUGH SUNDAY. THIS TO
ACCOUNT FOR THE POSSIBILITY THAT LOBES OF VORTICITY THAT USUALLY
ROTATE AROUND THE PARENT UPPER LOW MAY STILL LINGER OVER THE AREA.
&&
.MARINE...
GALE WARNINGS HAVE BEEN EXTENDED AND EXPANDED WITH THE AFTERNOON
FORECAST ISSUANCE AS ACTIVE MARINE CONDITIONS CONTINUE DUE TO BOTH
SHOWERS AND THUNDERSTORMS AND STRONG WINDS OVER THE REGION. DEEP LOW
PRESSURE WILL CONTINUE TO SUPPORT STRONG SOUTH WINDS SHIFTING TO
WEST DURING THE EVENING AND THEN NORTHWEST OVERNIGHT. THE STRENGTH
OF THE COLD FRONT WILL MAKE GALE FORCE WIND GUSTS LIKELY OVER ALL
MARINE AREAS EXCEPT THE MORE SHELTERED NEARSHORE WATERS OF SOUTHERN
LAKE HURON. OTHERWISE, MATCHING UPSTREAM OBSERVATIONS WITH THE
EVOLUTION OF THE SURFACE PRESSURE FIELD MAKES BELIEVABLE MODEL
DEPICTIONS OF A STRONG DYNAMIC COMPONENT TO THE WIND SPEED
ASSOCIATED WITH THE FRONT. THIS ALONG WITH INSTABILITY OVER THE WARM
LAKE WATER AND STRONG LOW LEVEL COLD ADVECTION WILL BE A GOOD
ENVIRONMENT FOR GALES THROUGH AT LEAST MONDAY MORNING AND INTO
MONDAY EVENING OVER THE OPEN WATERS OF LAKE HURON.
&&
.AVIATION...ISSUED 125 PM EDT SUN OCT 14 2012
//DISCUSSION...
EMBEDDED WITHIN THE ALREADY STRONG GRADIENT WIND TODAY WILL BE THE
POTENTIAL FOR ADDITIONAL ROUGH AVIATION WEATHER DUE TO CONVECTION.
EXPECT THE INCREASE IN COVERAGE AND INTENSITY OF SHOWERS AND
THUNDERSTORMS TO CONTINUE FROM SOUTHWEST LOWER INTO CENTRAL INDIANA
DURING THE MID AFTERNOON WITH ACTIVITY MOVING INTO SE MICHIGAN
DURING THE LATE AFTERNOON INTO EARLY EVENING. COVERAGE OF ACTUAL
LIGHTNING PRODUCING STORMS WILL BE GREATER IN THE DETROIT AREA
WITH THE BEST CHANCE AT METRO IN 21-24Z TIME WINDOW. TRENDS WILL
BE MONITORED TO THE NORTH FOR POSSIBLE LATER REFINEMENT.
AS THE UPPER LOW USHERS THE PRECIPITATION PATTERN EASTWARD, THE
STRONG COLD FRONT ASSOCIATED WITH THE SYSTEM WILL SWEEP THROUGH THE
REGION DURING THE EVENING. UPSTREAM OBSERVATIONS SUPPORT THE LATEST
MODEL DATA THAT INDICATES THE FRONT WILL BE ABLE TO SUSTAIN GUSTS
TO 35 KNOTS AS THE WIND SHIFTS TOWARD THE WEST. COVERAGE OF
SHOWERS WILL TEND TO CONSOLIDATE IN THE MBS AREA DURING THE EARLY
OVERNIGHT AS THE LOW PRESSURE SYSTEM WRAPS UP OVER SOUTHERN
ONTARIO. THIS WRAP-AROUND MOISTURE WILL SETTLE TOWARD THE DETROIT
AREA DURING MONDAY MORNING UNDER A GENERAL MVFR CEILING.
//DTW THRESHOLD THREATS...
* MEDIUM CONFIDENCE IN THUNDERSTORM TIMING DURING AFTERNOON AND
EVENING.
* HIGH CONFIDENCE IN CEILING BELOW 5000 FEET TONIGHT THROUGH MONDAY
MORNING.
