The episode as NWS DTX wrote it up.
A strong low pressure system tracking from the southern Plains into the Upper Great Lakes brought record December warmth to Southeast Michigan on Wednesday, December 23rd. Stronger winds associated with this system interacted with the unseasonably warm air to produce the first December tornado in Michigan history during the evening. This tornado occurred in Wayne County, just north-northeast of Canton. The tornado was rated EF-1 with peak winds of 90 mph. The tornado touched down at 643 pm EST, tracking 2 miles before lifting at 646 pm EST.
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 Detroit, MI wrote its last area forecast discussion before the first event at Dec 23, 3:23 PM EST, 2 hours 42 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
323 PM EST WED DEC 23 2015
.DISCUSSION...
STRONG SURFACE LOW HAS BEGUN ITS NEXT DEEPENING PHASE THIS AFTERNOON
AS VIGOROUS SHORTWAVE HAS ROUNDED THE BASE OF THE MEAN UPPER LEVEL
TROUGH OVER THE PLAINS/MIDWEST. THE 982MB LOW OVER EC IOWA WILL
DEEPEN TO ABOUT 974MB BY THE TIME IT REACHES LAKE SUPERIOR TONIGHT
AND THEN CONTINUE STRENGTHEN IS IT LIFTS TO JAMES BAY AND BEYOND ON
THURSDAY.
WARM FRONT IN ADVANCE OF THIS SYSTEM IS CURRENTLY WORKING NORTH
THROUGH THE FORECAST AREA WITH ALL LOCATIONS NOW CLIMB THROUGH THE
50S WITH A FEW 60 DEGREE READINGS NOTED SOUTH OF DETROIT. DEWPOINTS
WITHIN THIS MILDEST SECTOR HAVE ALSO CLIMBED INTO THE UPPER 50S AS
MODELS SUGGESTED WOULD OCCUR. AS THE WARM AND MOIST AIR CONTINUES TO
OVERSPREAD THE AREA...EXPECT TEMPERATURES TO CLIMB INTO THE 60S AREA
WIDE...SETTING RECORD HIGH TEMPERATURES FOR THE DAY AND ALSO SETTING
UP A MARGINALLY UNSTABLE AIRMASS OVER PARTS OF THE AREA BY THIS
EVENING.
THIS WILL ALLOW ONGOING STRONG TO LOCALLY SEVERE CONVECTIVE LINE
SEGMENTS FROM WESTERN INDIANA AND SOUTHEAST ILLINOIS TO WORK INTO
THE AREA EARLY THIS EVENING. THERE WILL MOST LIKELY BE A SLIGHT
WEAKENING TREND ONCE THIS ACTIVITY ENCROACHES ON THE AREA AS THE
AIRMASS STILL WILL NOT BE QUITE A UNSTABLE AS THE CURRENT AIR
FEEDING INTO ONGOING STORMS TO THE SOUTHWEST. THIS WILL RESULT IN
GUSTY WINDS WITH LOCALLY DAMAGING WIND GUSTS STILL POSSIBLE WITHIN
THE STRONGEST PORTIONS OF THE CONVECTIVE LINE(S) THAT MAKE IT THIS
FAR NORTHEAST.
WHILE A LOW LIKELIHOOD...AN ISOLATED TORNADO STILL CANNOT BE RULED
OUT GIVEN THE STRONG LOW LEVEL SHEAR THAT WILL BE IN PLACE ONCE THIS
ACTIVITY PROPAGATES INTO THE AREA. BY AND LARGE THE MOST LIKELY
SEVERE WEATHER SCENARIO WILL BE ISOLATED POCKETS OF 60 MPH WIND
GUSTS CAUSING SOME DAMAGE AS CONVECTION TAPS INTO THE 60+ KNOT LOW
LEVEL FLOW AND BRINGS SOME OF IT TO THE SURFACE AT TIMES.
ADDITIONAL SHOWERS OR THUNDERSTORMS WILL BE POSSIBLE FROM MID
EVENING INTO THE OVERNIGHT AS THE WARM AND MOIST AIRMASS REMAINS IN
PLACE AND EVEN BUILDS SLIGHTLY IN ADVANCE OF APPROACHING COLD FRONT
WHICH WILL CROSS THE AREA ROUGHLY BETWEEN 06Z-09Z. WITH THE SURFACE
LOW TRACK SO FAR TO THE NORTHWEST...BEST PUNCH OF WIND ALONG AND
BEHIND THIS FRONT WILL BE FOCUSED OVER THE NORTHERN CWA...AND WILL
LIMIT THE EXPECT WIND ADVISORY TO AREAS GENERALLY ALONG AND NORTH OF
INTERSTATE 69. THIS ADVISORY WILL BE RATHER SHORT LIVED AS WELL AS
THE RAPID MOVEMENT OF THE LOW INTO CANADA WILL ALLOW WINDS TO RELAX
RATHER QUICKLY THURSDAY MORNING.
MUCH QUIETER WEATHER WILL SET UP FOR THURSDAY AND FRIDAY AS HIGH
PRESSURE BUILDS EAST ACROSS THE AREA. WITH ONLY A MINOR INCURSION OF
COLDER POLAR AIR INTO AREA BEHIND THIS SYSTEM...TEMPERATURES...WHILE
COOLER...WILL REMAIN ABOVE AVERAGE FOR LATE DECEMBER. EXPECT HIGHS
IN THE 40S TO AROUND 50 THURSDAY AND IN THE 40S FRIDAY.
SURFACE LOW DEVELOPING NORTHEASTWARD ALONG BAROCLINIC ZONE PROGGED
TO MOVE THROUGH SE MI SAT. PLENTY OF MOISTURE TO BE LIFTED OVER THE
FRONTAL ZONE /PWAT NEAR 1.50 IN/ WILL SPELL LIKELY RAIN SAT/SAT
NIGHT AND POSSIBLY LINGERING INTO SUNDAY. THE RAIN COULD BE HEAVY
OVER THE SOUTH IF THE FRONT STAYS RELATIVELY STATIONARY AS SOME NWP
IS DEPICTING. THIS SHOULD BE MOSTLY RAIN BUT COULD BRIEFLY END AS
SNOW SAT NIGHT/SUN. ACCUMULATIONS DO NOT LOOK LIKELY AS THE MAJORITY
OF THE PRECIP WILL BE ON THE WARM SIDE. ATTENTION THEN TURNS TO
STRONG CUTOFF LOW EJECTING NWD FROM TX TO THE GREAT LAKES MON/TUE.
STILL SIGNIFICANT INTERMODEL AND RUN-TO-RUN MODEL DIFFERENCES IN
TIMING AND LOW TRACK...BUT ENOUGH CONFIDENCE TO GO WITH LIKELY POPS
CENTERED AROUND MONDAY NIGHT. P TYPE WILL BE TRICKY AND WILL NOT GET
TOO CUTE WITH THE DETAILS THIS FAR OUT. POTENTIAL DOES EXIST FOR
FZRA ON THE LEADING EDGE OF THE PRECIP. THE MOST LIKELY TIME FRAME
FOR THIS IS MONDAY NIGHT BEFORE WE GET INTO THE WARM SECTOR ON
TUESDAY AS DEPICTED BY THE EURO. MEANWHILE THE GFS HAS CONTINUED TO
TREND EASTWARD WITH THE LOW WHICH WOULD OPEN THE DOOR FOR SNOW FOR
PORTIONS OF OUR AREA. DUE TO MODEL DIFFERENCES AND LONG TIME
HORIZON...KEPT BROADBRUSH RAIN/SNOW MENTION FOR NOW.
&&
.MARINE...
A STRONG LOW PRESSURE SYSTEM WILL CONTINUE TO STRENGTHEN AS IT
TRACKS NORTH THROUGH THE WESTERN GREAT LAKES OVERNIGHT REACHING
JAMES BAY BY THURSDAY MORNING. THE LOW WILL PULL A COLD FRONT
THROUGH THE EASTERN GREAT LAKES LATE TONIGHT AROUND 09Z. STRONG
WINDS WILL OCCUR BOTH AHEAD OF...AND BEHIND THE COLD FRONT LEADING
TO A LONG DURATION GALE EVENT ACROSS LAKE HURON. THIS EVENING AHEAD
OF THE FRONT...ALREADY GUSTY WINDS WILL BE ENHANCED BY PREFRONTAL
RAIN SHOWERS MIXING DOWN STRONGER WINDS ALOFT MAINLY ACROSS NORTHERN
LAKE HURON. WINDS WILL THEN TURN WESTERLY AND INCREASE FURTHER AS A
TIGHT PRESSURE GRADIENT SOUTH OF THE LOW CENTER LIFTS UP THROUGH THE
REGION. WIND GUSTS WILL REACH STRONG GALE FORCE AROUND 45 KNOTS OVER
NORTHERN LAKE HURON. THE SOUTHERN END OF THE BASIN WILL BE FURTHER
REMOVED FROM THE TIGHTEST GRADIENT BUT SHOULD STILL SEE GALE FORCE
GUSTS OF 35 TO 40 KNOTS LATE TONIGHT INTO THURSDAY MORNING. WINDS
WILL THEN DIMINISH THROUGH THE DAY THURSDAY AS THE LOW QUICKLY LIFTS
NORTHWARD AWAY FROM THE LAKES. WIND GUSTS ARE EXPECTED TO DROP BELOW
20 KNOTS BY 06Z FRIDAY.
&&
.HYDROLOGY...
A LOW PRESSURE SYSTEM CURRENTLY OVER IOWA WILL CONTINUE TO
STRENGTHEN AS IT LIFTS NORTH THROUGH THE OVERNIGHT...REACHING JAMES
BAY BY THURSDAY MORNING. VERY WARM AND MOIST AIR LIFTING INTO THE
AREA AHEAD OF THE COLD FRONT WILL RESULT IN GOOD COVERAGE OF RAIN
SHOWERS THIS EVENING WITH ISOLATED THUNDERSTORMS POSSIBLE. MOST
LOCATIONS WILL RECEIVE AROUND 0.5 INCH OF RAIN BY THURSDAY MORNING
WITH ISOLATED TOTALS OF AROUND 1.0 INCH. LITTLE CONCERN FOR FLOODING
EXISTS.
&&
.AVIATION...ISSUED 1254 PM EST WED DEC 23 2015
WARM FRONT CURRENTLY LIFTING NORTH THROUGH LOWER MICHIGAN RESULTING
IN CONTINUED LIFR/IFR CONDITIONS INTO THE AFTERNOON HOURS. ELEVATED
FRONT SEEN ON RADAR PRODUCING SHOWERS BUT ACTUAL SURFACE FRONT
REMAINS QUITE DIFFUSE. SHOULD SEE SOME IMPROVEMENTS LATER THIS
AFTERNOON AS WE GET DEEPER INTO THE WARM SECTOR WITH CIGS LIFTING TO
MVFR. THIS WILL LAST A FEW HOURS BEFORE PRE FRONTAL SHOWERS AND
THUNDERSTORMS TRACK EAST THROUGH THE AREA. THE COLD FRONT WILL
FOLLOW AROUND 09Z SWITCHING WINDS FROM SOUTHERLY TO SOUTHWEST. WIND
SPEEDS WILL INCREASE DRAMATICALLY WITH GUSTS POSSIBLY EXCEEDING 35
KNOTS FOR ALL TAF SITES...AND POSSIBLY OVER 45 KNOTS FOR MBS AND
FNT. ON THURSDAY WINDS WILL GRADUALLY DECREASE WHILE DRIER AIR ALOFT
PRODUCES CLEARING SKIES.
FOR DTW...IFR/LIFR WILL LINGER A FEW MORE HOURS BEFORE FINALLY
LIFTING TO MVFR AS WE GET DEEPER INTO THE WARM SECTOR. MAY BE A
COUPLE BRIEF PERIODS OF DRIZZLE BUT SHOULD NOT PERSIST LONG AT ALL.
SHOWERS AND POSSIBLY THUNDERSTORMS WILL APPROACH THE TERMINAL AROUND
00-03Z THIS EVENING AHEAD OF A COLD FRONT. MAIN THREAT WILL BE
STRONG WINDS ALOFT MIXING DOWN TO THE SURFACE. LONGER DURATION WIND
EVENT WILL OCCUR AFTER THE COLD FRONTAL PASSAGE AROUND 09Z WHERE
GUSTS WILL REACH 30 TO 35 KNOTS.
//DTW THRESHOLD PROBABILITIES...
* HIGH FOR CEILING BELOW 5000 FEET THROUGH TONIGHT.
* LOW FOR CIGS/VSBY BELOW 200FT AND/OR 1/2SM THIS AFTERNOON.
* MEDIUM THAT THUNDERSTORMS WILL IMPACT THE TERMINAL BETWEEN 00-03Z.
* MODERATE TO HIGH FOR GUSTS EXCEEDING CROSSWIND THRESHOLD AFTER 09Z.

BTThe Detroit radar (KDTX), 101 km away, was scanning. The volume nearest the first event began at 23:07 UTC.
3 thunderstorm wind, 1 tornado. Local standard time, as filed.
Multiple roofs were blown off in a mobile home park.
A barn was reported destroyed.
A wind damage swath was observed where multiple trees were downed. Shingles were blown off two roofs, and an out building destroyed. Two barn roofs were also blown off.
An NWS damage survey determined that a tornado touched down in a neighborhood just southwest of the intersection of Warren and North Lilley Roads in Canton. Several pine trees were knocked down along with other large tree limbs. EF-1 damage was then found at a light industrial complex on the southwest side of the Canton Airport where multiple buildings and vehicles were damaged. Additional EF-0 damage was found near the intersection of Joy and Haggerty roads were a metal roof was taken off a gas station and more trees were damaged. The tornado then lifted near Haggerty Road and Newport Drive.
