Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS OUN wrote it up.
A large upper trough developed over the western U.S. with upper level winds supportive of severe storms. At the surface, a cold front and dryline surged into western Oklahoma during the late afternoon and evening hours on the 10th. Despite very favorable wind fields and forcing for severe storms, lack of quality moisture kept most storms below severe levels. A couple of storms, however, managed to become severe and produce large hail and damaging wind gusts.
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 Norman, OK wrote its last area forecast discussion before the first event at Nov 10, 5:48 PM CST, 1 hour 37 minutes earlier.

.PREV DISCUSSION... /ISSUED 249 PM CST SAT NOV 10 2012/
DISCUSSION...
WE WILL EXTEND THE WIND ADVISORY THROUGH THE EVENING HOURS ACROSS
CENTRAL PORTIONS OF OKLAHOMA DOWN INTO NORTHERN PARTS OF OUR TEXAS
COUNTIES. WITH TIGHT SFC PRESSURE GRADIENT SHOULD ALLOW BLYR TO
REMAINED MIXED ENOUGH TO ALLOW STRONGER GUSTS TO CONTINUE WELL
PAST SUNSET. ALL MODELS WEAKEN WIND ACROSS FAR WESTERN OKLAHOMA
TOWARD AND AFTER 00Z NEAR AND WEST OF DRYLINE WHERE GRADIENT
WEAKENS AND DRIER AIR ALLOWS MORE EFFICIENT DECOUPLING.
STRONG TO SEVERE STORMS STILL EXPECTED TO DEVELOP ACROSS FAR
WESTERN PARTS OF FORECAST AREA BY EARLY EVENING THEN PROGRESS
EASTWARD OVERNIGHT AND SUNDAY AS DRYLINE PUSHES EAST. SOME OF THE
STORMS MAY BECOME SEVERE WITH DAMAGING WINDS AND MARGINAL HAIL.
LOW LEVEL CIN WILL BE HARD TO OVERCOME FOR MUCH IN THE WAY OF
SURFACE BASED CONVECTION AHEAD OF ANY NARROW SQUALL LINE.
STRONG FRONT WILL ENTER NORTHWEST OKLAHOMA TOMORROW MORNING AND
USHER IN THE MUCH COOLER AIR AS ADVERTISED. FREEZING TEMPS WILL BE
WIDESPREAD SUNDAY NIGHT AND POSSIBLY AGAIN MONDAY NIGHT OVER MUCH
OF THE REGION. MODELS COMING IN MUCH SLOWER WITH EVOLUTION OF SW
SYSTEM AND NEXT CHANCE FOR RAIN. LOOKS LIKE IT WILL BE LATE NEXT
WEEK INTO NEXT WEEKEND.

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.
.DAY ONE...TODAY AND TONIGHT...
THUNDERSTORM OUTLOOK...
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THROUGH TONIGHT
ACROSS PORTIONS OF OKLAHOMA AND WESTERN NORTH TEXAS.
LOCATION...
THE SLIGHT RISK AREA EXTENDS ALONG AND WEST OF A LINE FROM PONCA
CITY...TO STILLWATER...TO OKLAHOMA CITY...TO GRANDFIELD IN
OKLAHOMA...AND FROM ELECTRA TO KNOX CITY IN WESTERN NORTH TEXAS.
TIMING...
THE MOST LIKELY TIME FOR THUNDERSTORMS WILL BE FROM 6 PM THIS
EVENING THROUGH 2 AM SUNDAY.
IMPACTS...
THE MAIN HAZARDS WITH ANY SEVERE THUNDERSTORMS WILL BE DAMAGING
WIND GUSTS TO 70 MPH...WHICH MAY RESULTS IN DOWNED TREES AND POWER
LINES...AND LARGE HAIL TO THE SIZE OF HALF DOLLARS...WHICH MAY CAUSE
LIGHT DAMAGE TO AUTOMOBILES AND ROOFS OF HOMES.
RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD PLAN FOR SEVERE WEATHER OPERATIONS FROM LATE THIS
AFTERNOON THROUGH EARLY SUNDAY MORNING.
DISCUSSION...
A POTENT FALL COLD FRONT WILL SWEEP INTO THE OKLAHOMA AND TEXAS
PANHANDLES LATE TONIGHT. AHEAD OF THE FRONT...A DRYLINE WILL MOVE
INTO WESTERN OKLAHOMA BY LATE AFTERNOON AND EARLY EVENING. MODEST
MOISTURE AND VERY WARM AFTERNOON TEMPERATURES WILL LEAD TO
INCREASING INSTABILITY ACROSS MUCH OF OKLAHOMA AND NORTH TEXAS. THIS
COMBINED WITH STRONG UPPER LEVEL WINDS WILL BE SUPPORTIVE OF
SUSTAINED SEVERE THUNDERSTORMS. HOWEVER...A STRONG CAPPING INVERSION
WILL SUPPRESS THUNDERSTORM FORMATION FOR MOST OF THE DAY. AS THE
DRY LINE MOVES INTO NORTHWEST OKLAHOMA...STRONG LIFT IS EXPECTED TO
LEAD TO SCATTERED THUNDERSTORMS OVER FAR WESTERN OKLAHOMA AND
WESTERN NORTH TEXAS AROUND SUNSET. THE INITIAL STORMS MAY BE
SEVERE...POSING A THREAT OF LARGE HAIL AND DAMAGING WINDS. THE
STORMS ARE EXPECTED TO MERGE INTO A SQUALL LINE LATE THIS EVENING
AND OVERNIGHT. DECREASING INSTABILITY WILL MAKE SEVERE THUNDERSTORMS
LESS LIKELY AFTER MIDNIGHT...BUT STRONG AND GUSTY WINDS CAN BE
EXPECTED WITH ANY STORMS GIVEN THE VERY STRONG WINDS JUST OFF THE
SURFACE.
PROBABILITY TABLE...
VALID THROUGH 700 AM CST SUNDAY NOV 11.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...100 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...50 PERCENT.
OTHER HAZARDOUS WEATHER...
STRONG AND GUSTY SOUTHWEST WINDS ARE EXPECTED TODAY AHEAD OF THE
DRY LINE AND COLD FRONT. SUSTAINED WINDS OF 20 TO 30 MPH...WITH
GUSTS UP TO 45 MPH WILL BE POSSIBLE ACROSS MUCH OF OKLAHOMA AND
WESTERN NORTH TEXAS. SECURE LIGHT-WEIGHT LOOSE OBJECTS AND EXERCISE
CAUTION IF TRAVELING IN HIGH PROFILE VEHICLES...ESPECIALLY ON EAST
WEST ROADWAYS. ELEVATED WINDS AND TEMPERATURES WILL ALSO LEAD TO
VERY HIGH FIRE DANGER ACROSS WESTERN OKLAHOMA AND WESTERN NORTH
TEXAS.
.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY...
SHOWERS AND THUNDERSTORMS WILL CONTINUE SUNDAY MORNING ACROSS PARTS
OF CENTRAL AND EASTERN OKLAHOMA AS A SQUALL LINE MOVES THROUGH
OKLAHOMA AND INTO THE ARKLATEX REGION. ISOLATED SEVERE WIND GUSTS
AND PERHAPS MARGINALLY SEVERE HAIL WILL REMAIN POSSIBLE WITH THE
STRONGEST STORMS...BUT WIDESPREAD SEVERE WEATHER IS NOT ANTICIPATED.
BY MONDAY...A MUCH COOLER AND DRIER AIRMASS WILL HAVE SETTLED INTO
THE SOUTHERN PLAINS. THIS WILL PREVENT THUNDERSTORMS FROM DEVELOPING
FOR MUCH OF THE COMING WEEK. ANOTHER STORM SYSTEM WILL APPROACH
OKLAHOMA AND NORTH TEXAS LATE NEXT WEEK AND INCREASE THUNDERSTORM
CHANCES AGAIN.
OTHER HAZARDOUS WEATHER...
AS COLDER AIR MOVES INTO THE SOUTHERN PLAINS BEHIND THE COLD
FRONT...FREEZING TEMPERATURES WILL BE LIKELY IN SOME
AREAS...PARTICULARLY ON MONDAY AND TUESDAY MORNINGS. FREEZE WATCHES
AND OR WARNINGS WILL LIKELY BE NEEDED IN FUTURE OUTLOOKS.
THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AROUND
5 AM SUNDAY.
