The episode as NWS OUN wrote it up.
A line of thunderstorms with heavy rainfall developed over parts of southern Oklahoma during the evening hours and continued for several hours of the 6th. The line moved little and widespread Rainfall totals of 5-9 inches were reported across parts of Jefferson, Carter and Murray counties. Numerous roadways had to be closed due to the them being impassable. A few buildings also took in water, especially near Turner Falls and Sulphur. The rainfall finally moved further north early on the 7th, with less flooding reported.
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 6, 9:48 PM CST, 1 hour 12 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 948 PM CST SUN NOV 6 2011 .AVIATION... LITTLE CHANGE FROM PREV FORECAST. THUNDERSTORMS CONTINUE VICINITY OF WEAK SURFACE BOUNDARY FROM N TX INTO CENTRL OK. EXPECT THUNDERSTORMS TO GRADUALLY EXPAND NWWD OVERNIGHT AS UPPER TROUGH APPROACHES. WIDESPREAD MVFR/IFR CIGS EXPECTED WITH WIDEPSREAD SHOWERS AND THUNDERSTORMS ALSO EXPECTED. && .PREV DISCUSSION... /ISSUED 948 PM CST SUN NOV 6 2011/ .UPDATE... PRECIPITATION DEVELOPMENT ON SCHEDULE THIS EVENING... WITH A DECENT LINE OF THUNDERSTORMS EXTENDING FROM THE EASTERN PORTION OF OUR TEXAS COUNTIES... NORTHEAST INTO PARTS OF CENTRAL OKLAHOMA. HEAVY RAINFALL HAS BEEN THE MAIN STORY WITH THE THUNDERSTORMS... ESPECIALLY OVER PARTS OF SOUTH CENTRAL OKLAHOMA AND ADJACENT AREAS OF WESTERN NORTH TEXAS. AREAS FROM SOUTHEAST JEFFERSON TO PARTS OF CLAY COUNTY HAVE LIKELY SEEN OVER TWO INCHES OF RAINFALL. WILL MONITOR RADAR TRENDS FOR THE POSSIBILITY OF ANY HYDRO PRODUCT NECESSITY. WE WILL ALSO HAVE TO MONITOR VISIBILITY TRENDS TO THE NORTHEAST OF A SLOW MOVING WARM FRONT THAT IS NEAR THE I-44 CORRIDOR. DEW POINT TEMPERATURES IN THE LOWER 60S ADVECTING INTO 30S AND LOW 40S MAY YIELD SOME FOG FORMATION. THE BOUNDARY HAS SLOWED OVER THE LAST FEW HOURS... BUT WE DO EXPECT IT TO ONCE AGAIN MOVE NORTH AND WEST AS WINDS OFF THE SURFACE RESPOND TO THE STRONG STORM SYSTEM MOVING TOWARD THE SOUTHERN PLAINS. ZFP OUT SHORTLY. && .PREV DISCUSSION... /ISSUED 545 PM CST SUN NOV 6 2011/ AVIATION... LOW CLOUDS SHOULD SPREAD BACK NWWD THIS EVENING WITH WIDESPREAD MVFR/IFR CONDITIONS EXPECTED. SCATTERED SHOWERS/ISOLD TSTMS FROM N TX INTO SE OK MAY AFFECT AREAS FROM KSPS TO KOKC THIS EVENING WITH PRECIP BECOMING MORE WIDESPREAD LATER TONIGHT INTO MONDAY. PREV DISCUSSION... /ISSUED 358 PM CST SUN NOV 6 2011/ DISCUSSION... LOW CLOUDS REMAIN ACROSS SOUTH CENTRAL AND SOUTHEAST OKLAHOMA AT MID AFTERNOON WITH WIDELY SCATTERED SHOWERS OCCURRING ON THE WESTERN FRIDGE OF THE CLOUD COVER. LOW CLOUDS SHOULD BEGIN TO PUSH AND DEVELOP BACK TO THE WEST AND NORTH THIS EVENING AND OVERNIGHT AS A STRONG TROUGH APPROACHES FROM THE WEST. SHOWERS AND SOME THUNDERSTORMS ARE EXPECTED TO BECOME MORE NUMEROUS AS BETTER MOISTURE IS LIFTED NORTHWARD. ELEVATED INSTABILITY AND DEEP LAYER SHEAR SHOULD BE SUFFICIENT FOR SOME SEVERE HAIL REPORTS. SOME ADVECTION FOG MAY FORM ACROSS PARTS OF NORTHWEST OKLAHOMA BY EARLY MONDAY MORNING MAINLY ALONG AND NORTHWEST OF A FRONTAL BOUNDARY. WIDESPREAD SHOWERS AND THUNDERSTORMS ARE EXPECTED MONDAY INTO MONDAY NIGHT AS THE UPPER TROUGH MOVES ACROSS ARIZONA AND NEW MEXICO. STILL SOME UNCERTAINTIES WITH REGARDS TO SEVERE WEATHER POTENTIAL DURING THIS TIME PERIOD. WIDESPREAD RAINFALL AND CLOUDS MAY LIMIT THE AMOUNT OF INSTABILITY FOR STRONG TO SEVERE STORMS...BUT SOUTHWEST 1/4 OF THE FA APPEARS TO BE MOST LIKELY AREA FOR SEVERE STORMS WITH LARGE HAIL (GOLFBALLS) AND DAMAGING WINDS. THE MAIN UPPER TROUGH SHOULD MOVE EAST OF THE AREA BY MID TO LATE DAY TUESDAY. COOLER AND MUCH DRIER AIR WILL MOVE INTO REGION BEHIND THIS SYSTEM...WITH A GRADUAL WARM UP AFTER WEDNESDAY. GFS SHOWS ANOTHER SYSTEM APPROACHING THE AREA AROUND SUNDAY OF NEXT WEEKEND.

.DAY ONE...THIS AFTERNOON AND TONIGHT...
THUNDERSTORM OUTLOOK...
SCATTERED THUNDERSTORMS ARE EXPECTED TONIGHT...AND SOME MAY PRODUCE
HAIL.
DISCUSSION...
GULF MOISTURE WILL STEADILY INCREASE THROUGH TONIGHT AS A STORM
SYSTEM APPROACHES FROM THE WEST. THIS WILL RESULT IN WEAK TO
MODERATE INSTABILITY. BY MID EVENING...A DEVELOPING LOW LEVEL JET
WILL PROVIDE LIFT...WHILE ALSO TRANSPORTING MORE UNSTABLE AIR
NORTHWARD FROM CENTRAL TEXAS. THIS WILL LEAD TO THUNDERSTORM
DEVELOPMENT IN THE EVENING AND OVERNIGHT HOURS GENERALLY FROM
SOUTHERN OKLAHOMA UP THROUGH CENTRAL AND EASTERN OKLAHOMA. STORMS
MAY THEN DEVELOP BACK TOWARD WESTERN NORTH TEXAS AND WESTERN
OKLAHOMA LATE IN THE NIGHT.
ANY OF THE STORMS THAT FORM TONIGHT WILL BE CAPABLE OF PRODUCING
MARGINALLY SEVERE HAIL SLIGHTLY LARGER THAN QUARTERS. IF A STORM CAN
REMAIN ISOLATED FOR ANY LENGTH OF TIME...THE SHEAR WILL ALSO FAVOR
MESOCYCLONES THAT COULD ENHANCE THE CHANCE OF DAMAGING WINDS...
MAINLY IN SOUTHERN OKLAHOMA.
PROBABILITY TABLE...
VALID THROUGH 700 AM CST MONDAY NOV 7.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...70 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...40 PERCENT.
OTHER HAZARDOUS WEATHER...
NONE.
.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY...
THUNDERSTORM OUTLOOK...

NIGHT. EARLY IN THE DAY THE PRIMARY HAZARD WILL BE MARGINALLY SEVERE
HAIL. DURING THE AFTERNOON AND EVENING... HOWEVER...AN ORGANIZED
EVENT MAY UNFOLD...WITH SUPERCELL STORMS GRADUALLY MERGING TO FORM A
SQUALL LINE. THIS WILL LIKELY OCCUR FROM WEST TEXAS INTO SOUTHWEST
OKLAHOMA...AND THE RISK OF SEVERE WEATHER IS GREATEST TO THE WEST OF
A LINE FROM CHEYENNE TO CHICKASHA TO HENRIETTA TEXAS. THE SQUALL
LINE MAY CONTINUE TO PRODUCE STRONG WINDS AS IT MOVES EAST ACROSS
