Although much of the severe weather remained north of the Red River, a particularly nasty supercell thunderstorm began over far northern Wilbarger county. The tornado was only briefly in the county before it crossed the river into Jackson county, Oklahoma.

The episode as NWS OUN wrote it up.
Although much of the severe weather remained north of the Red River, a particularly nasty supercell thunderstorm began over far northern Wilbarger county. The tornado was only briefly in the county before it crossed the river into Jackson county, Oklahoma.
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 7, 10:49 AM CST, 3 hours 49 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 1049 AM CST MON NOV 7 2011 .DISCUSSION... A WARM FRONT IS MAKING FAIRLY STEADY PROGRESS TO THE NORTHWEST THIS MORNING. IT HAS BEEN SOMEWHAT DIFFICULT TO LOCATE AT TIMES...DUE TO THE PRESENCE OF A COUPLE OF MOISTURE GRADIENTS. THE POSITION LATE THIS MORNING APPEARS TO BE FROM ABOUT CHEYENNE...TO ENID...TO MEDFORD. NUMEROUS SHOWERS AND THUNDERSTORMS WERE ALONG AND NORTH OF THE FRONT. ADDITIONAL SHOWERS AND STORMS WERE NUMEROUS OVER CENTRAL OKLAHOMA AS WELL...AS LARGE QUANTITIES OF LOW-LEVEL MOISTURE CONTINUED TO STREAM NORTH INTO NORTH TEXAS AND OKLAHOMA. A FEW BREAKS IN THE CLOUDS WERE NOTED OVER WESTERN NORTH TEXAS AND SOUTHWEST OKLAHOMA. THIS IS IN LINE WITH THE OVERALL PLAN FOR TODAY...IN WHICH CLOUDS BREAK UP SOMEWHAT IN OUR SOUTHWEST COUNTIES...ENHANCING THE RISK OF SEVERE STORMS THERE. THE LATEST SHORT-RANGE MODELS CONTINUE TO SUPPORT THE IDEA THAT SUPERCELLS WILL FORM THIS AFTERNOON...THEN STORMS WILL FORM INTO A LONG LINE THIS EVENING. THE LINE WILL THEN ADVANCE EAST ACROSS OUR FORECAST AREA TONIGHT AND TOMORROW. ONLY MINOR CHANGES WERE MADE TO THE FORECAST THIS MORNING. && .PREV DISCUSSION... /ISSUED 603 AM CST MON NOV 7 2011/ AVIATION... AREAS OF IFR CEILINGS AND FOG WILL OCCUR OVER PORTIONS OF NORTHERN AND WESTERN OK THROUGH MID-MORNING AS LOW LEVEL MOISTURE CONTINUES TO ADVECT TO THE NORTHWEST OVER COOL GROUND. ELSEWHERE... MVFR CEILINGS AND LIGHT FOG WILL BE COMMON. SCATTERED T-STORMS WILL BE SPREADING NORTH FROM SW OK INTO NORTHERN OK THROUGH MIDDAY. T-STORMS WILL BECOME MORE WIDESPREAD BY TONIGHT AS A STRONG UPPER LEVEL STORM SYSTEM APPROACHES. SCATTERED SEVERE STORMS WILL BE POSSIBLE THIS AFTERNOON AND EVENING MAINLY ACROSS SW OK AND WESTERN N-TX. PREV DISCUSSION... /ISSUED 436 AM CST MON NOV 7 2011/ DISCUSSION... SCATTERED THUNDERSTORMS OCCURRING FROM SW OK INTO E-CENTRAL OKLAHOMA WILL CONTINUE TO SPREAD TO THE NE THIS MORNING. THE ACTIVITY IS OCCURRING IN AREA OF DEEPER MOISTURE AND WARM ADVECTION SITUATED NEAR THE NOSE OF THE LOW LEVEL JET. TRAINING ECHOES OVERNIGHT LED TO A NARROW BAND OF HEAVY RAIN IN SOUTH CENTRAL OKLAHOMA... WITH AMOUNTS OF 4 TO NEAR 7 INCHES. ACTIVITY HAS BECOME MORE PROGRESSIVE SINCE THEN WITH RECENT RAINFALL AMOUNTS ON THE ORDER OF 1 TO 2 INCHES. MEANWHILE... LOW LEVEL SOUTHEAST WINDS CONTINUE TO ADVECT DEWPOINTS IN THE LOWER TO MID 60S NORTH THROUGH CENTRAL OKLAHOMA. A TRANSITORY BAND OF FOG HAS BEEN DEVELOPING FROM NORTH CENTRAL INTO SW OK AS THE MOIST AIR MOVES OVER COOLER GROUND. ADDITIONAL THUNDERSTORM DEVELOPMENT IS EXPECTED TO OCCUR LATE TODAY AND THROUGH THE NIGHT AS A STRONG UPPER LEVEL STORM SYSTEM... CURRENTLY MOVING THROUGH ARIZONA... APPROACHES THE AREA. THERE WILL BE A POTENTIAL FOR SEVERE THUNDERSTORMS... INCLUDING SUPERCELLS... THIS AFTERNOON AND EVENING. THE MOST LIKELY AREA FOR THE STRONGEST STORMS CURRENTLY APPEARS TO BE IN SOUTHWEST OKLAHOMA AND WESTERN NORTH TEXAS. THE DEEP LAYER SHEAR WILL CONTINUE TO INCREASE TODAY AS THE UPPER SYSTEM APPROACHES. THE DISTRIBUTION OF CONVECTION AND CLOUD COVER THROUGH EARLY AFTERNOON WILL MODULATE THE LEVEL OF INSTABILITY THAT DEVELOPS BY LATE THIS AFTERNOON. THE NAM GENERATES AN INSTABILITY MAXIMA FOR LATER TODAY OVER PORTIONS OF OUR TX COUNTIES AHEAD OF A SHARPENING DRYLINE OVER WEST TEXAS. THIS INSTABILITY FIELD COULD ALSO BE ADVECTED NORTHWARD INTO SW OK BY A STRENGTHENING LOW LEVEL JET. MORE WIDESPREAD CLOUDS AND RAIN IN THIS AREA WOULD DIMINISH THE POTENTIAL FOR HIGHER INSTABILITIES. OUR CURRENT THINKING... ASSUMING SUFFICIENT INSTABILITY IS AVAILABLE... CALLS FOR SCATTERED THUNDERSTORMS... SOME OF THEM SUPERCELLS... TO DEVELOP THIS AFTERNOON AND/OR EVENING. THE CONVECTION IS THEN EXPECTED TO ORGANIZE INTO A MORE LINEAR SQUALL LINE REGIME LATER TONIGHT AS A COLD FRONT AND DRYLINE BEGIN ADVANCING EAST ACROSS THE AREA. LOCALLY HEAVY RAINFALL COULD ALSO BECOME A CONCERN ONCE AGAIN TONIGHT DEPENDING ON HOW QUICKLY THE SQUALL LINE ADVANCES TO THE EAST. PRECIPITABLE WATER AMOUNTS APPROACHING 1.4 INCHES ACROSS THE AREA ARE QUITE HIGH COMPARED TO THE CLIMATOLOGICAL NORM FOR THIS TIME OF YEAR. THIS WAS EVIDENCED BY THE EFFICIENT RAIN PRODUCING STORMS THAT OCCURRED EARLY THIS MORNING. BY TUESDAY MORNING... MOST OF THE ACTIVITY SHOULD BE CONFINED TO CENTRAL AND EASTERN OKLAHOMA BEFORE IT COMES TO AN END IN THE EAST BY EARLY TUESDAY EVENING. DRY AND COOLER AIR WILL SPREAD INTO THE REGION FOR WEDNESDAY AND THURSDAY WITH TEMPERATURES THEN WARMING BY THE WEEKEND. && .PRELIMINARY POINT TEMPS/POPS...

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 MUCH OF OKLAHOMA AND ALL OF WESTERN NORTH TEXAS. SEVERE
WEATHER IS MORE LIKELY TO OCCUR THIS AFTERNOON AND EVENING OVER WEST
CENTRAL AND SOUTHWEST OKLAHOMA AND ADJACENT PARTS OF NORTH TEXAS.
LOCATION...
THE AREA MOST AT RISK IS WEST OF SEILING...WEATHERFORD...LAWTON AND
WICHITA FALLS.
TIMING...
THE MOST LIKELY TIME FOR SEVERE THUNDERSTORMS IS FROM 2 PM
UNTIL 9 PM.
IMPACTS...
SOME DAMAGE TO AUTOMOBILES AND ROOFTOPS FROM LARGE HAIL. THE LARGEST
HAIL MAY BE GREATER THAN TWO INCHES DIAMETER.
DAMAGING STRAIGHT LINE WINDS AND TORNADOES.
RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD PLAN FOR SEVERE WEATHER OPERATIONS FROM 2 PM UNTIL
9 PM.
DISCUSSION...
A VERY HUMID AIRMASS EXISTS AND IS EXPECTED TO MAINTAIN ITSELF
ACROSS ALL BUT NORTHWEST OKLAHOMA. THINNING CLOUDS ACROSS THE
SOUTHERN TEXAS PANHANDLE WILL ALLOW WARMER SURFACE AIR TO MOVE INTO
SOUTHWEST OKLAHOMA AND ADJACENT PARTS OF NORTH TEXAS THIS AFTERNOON.
AN UPPER LEVEL TROUGH ARRIVING FROM THE WEST WILL PROVIDE INCREASED
ENERGY TO ALLOW STRONG AND SEVERE THUNDERSTORMS FROM
MID-AFTERNOON UNTIL MID-EVENING. THE WIND PROFILE WILL BECOME
INCREASINGLY FAVORABLE FOR SUPERCELL THUNDERSTORMS. THERE IS A
CONSIDERABLE RISK OF TORNADOES WITH SOME OF THE THUNDERSTORMS. THE
SUPERCELL THUNDERSTORMS WILL MOVE VERY QUICKLY TO THE NORTHEAST.
PERSONS IN WESTERN OKLAHOMA AND ADJACENT PARTS OF TEXAS SHOULD
REVIEW SEVERE WEATHER SAFETY RULES AND HAVE A PLAN OF ACTION. IN
ADDITION TO THE TORNADO POTENTIAL...SOME THUNDERSTORMS ARE EXPECTED
TO PRODUCE DAMAGING HAIL.
DURING THE EVENING A LINE OF THUNDERSTORMS IS EXPECTED TO FORM IN
WESTERN OKLAHOMA. THE MAIN HAZARDS WILL THEN BECOME HEAVY RAIN AND
DAMAGING WIND. THESE THUNDERSTORMS ARE EXPECTED TO MOVE WEST TO EAST
ACROSS MOST OF OKLAHOMA OVERNIGHT.
PROBABILITY TABLE...
VALID THROUGH 700 AM CST TUESDAY NOV 8.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...100 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...90 PERCENT.
OTHER HAZARDOUS WEATHER...

FLOODING...ESPECIALLY IN SOUTH CENTRAL OKLAHOMA.
.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY...
THUNDERSTORM OUTLOOK...

OVER SOUTHEAST OKLAHOMA. DRY WEATHER IS THEN FORECAST FOR SEVERAL
DAYS UNTIL A CHANCE OF THUNDERSTORMS RETURNS ON SUNDAY.
OTHER HAZARDOUS WEATHER...
LIMITED FROST AND FREEZING TEMPERATURES MAY OCCUR THURSDAY AND
FRIDAY MORNINGS.
THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT 5 AM
