The episode as NWS OUN wrote it up.
Moist, tropical air remained in place over northern Texas, with scattered showers and thunderstorms remaining a daily late morning into the afternoon occurrence. A weak boundary stalled close to I-44 by early afternoon. Weak flow aloft did not allow for much movement of any thunderstorm, and with precipitable water values well over two inches, intense rainfall occurred over many areas. Flash flooding occurred over parts of northern Texas, and several roadways had to be closed due to water over top of them. The rainfall intensity and coverage decreased with the loss of daytime heating.
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 Jul 8, 3:17 AM CST, 6 hours 27 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
417 AM CDT THU JUL 8 2010
.DISCUSSION...FLASH FLOOD WATCH CONTINUES TODAY. SATELLITE DATA
ESTIMATING SOME INCREASE TO PRECIPITABLE WATER VALUES OVERNIGHT IN
THE VICINITY OF AN INVERTED TROUGH AXIS FROM NORTH TEXAS THROUGH
SOUTHEAST OKLAHOMA. MOISTURE IS SOMEWHAT LESS DEEP...BUT NO LESS
CAPABLE OF SUPPORTING HEAVY RAIN OVER THE REMAINDER OF THE REGION.
THE MAIN DIFFICULTY IS FORECASTING WHERE LIFTING MECHANISMS WILL
BECOME ORGANIZED. TRENDS SUGGEST IT MAY BE DIFFICULT TO FIND SUCH
ORGANIZATION IN OUR FORECAST AREA...OR AT LEAST THAT THE HEAVY RAIN
THREAT WILL BE SOMEWHAT MORE CONFINED IN AREAL COVERAGE BY THIS
EVENING.
THE ENTRANCE REGION OF AN UPPER JET NOW STRENGTHENING TO OUR NORTH...
AS WELL AS A SMALL WARM CORE LOW /LOCATED JUST EAST OF OKC/ WERE
SUPPORTING SCATTERED DOWNPOURS THIS MORNING. A COLD FRONT EXTENDED
FROM NEAR KANSAS CITY TO WICHITA TO THE OKLAHOMA PANHANDLE. THE
FRONT WAS MASKED SOMEWHAT BY NORTHERLY WINDS AHEAD OF IT...OWING TO
OUTFLOWS AND AN INVERTED SURFACE TROUGH THAT CAME UP FROM THE GULF
COAST YESTERDAY. WHILE THE MODELS ARE SIMILAR IN MOVING THE FRONT
THROUGH OKLAHOMA TODAY...IT APPEARS BASED ON OBS AND SATELLITE...
THAT THE NAM AND ECMWF HAVE A BETTER HANDLE ON THE NORTHERN JET
STREAM. THE RESULT IS A FLATTER...MORE ZONAL WESTERLY FLOW
DEVELOPING BEHIND THE COLD FRONT. THIS SETUP WILL TEND TO VEER
THE LOW LEVEL FLOW ALONG THE FRONT LATER TODAY...WHILE THE SLOW
AMPLIFICATION OF A TROPICAL WAVE IN SOUTH TEXAS ALSO DISRUPTS THE
LOW LEVEL FLOW UP INTO OUR AREA. THIS PLACES US IN A COL AREA AT
850-700 MB. HEATING AND CONVERGENCE IN THE FRONTAL ZONE SHOULD YIELD
WIDESPREAD DIURNAL THUNDERSTORMS WITH POTENTIAL FOR INTENSE RAIN
RATES. THE LACK OF INFLOW IN THE 850-700 MB LAYER...HOWEVER...
SUGGESTS STORMS WILL BE OF THE PULSE VARIETY...AND MAY NOT ANCHOR
OVER A PARTICULAR LOCATION FOR TOO LONG...AND MAY STRUGGLE TO GROW
UPSCALE. IF UPSCALE GROWTH INTO AN MCV DOES NOT OCCUR...THEN THE
ACTIVITY MAY TEND TO SHRINK IN COVERAGE OVERNIGHT. THIS IS CERTAINLY
REFLECTED IN THE NAM QPF. IT IS ALSO WORTH NOTING THAT AN MCV
ASSOCIATED WITH HIGH IMPACT FLOODING AT AMARILLO TEXAS THIS
MORNING...IS EMBEDDED WITHIN WEAK SOUTHERLY FLOW AT 600 MB...AND
SHOULD HAVE LITTLE INFLUENCE ON OUR FORECAST AREA.
WE CONSIDERED REMOVING A FEW NORTHERN OK COUNTIES FROM THE FLASH
FLOOD WATCH...BUT DECIDED IT WAS A BIT PREMATURE...AT LEAST UNTIL
THE FRONT MOVES THROUGH THAT REGION THIS MORNING. BASED ON THE NAM
FRONTAL/TROUGH STRUCTURE UP THROUGH 600 MB...THE DAY SHIFT MAY BE
ABLE TO REMOVE COUNTIES ROUGHLY NORTH OF A LINE FROM BECKHAM TO
GARFIELD TO NOBLE WITH THE AFTERNOON FORECAST PACKAGE.
BY FRIDAY EVENING...NORTHWEST FLOW HAS SET IN ALOFT...AND MID LEVEL
RIDGING ACROSS TEXAS SHOULD KEEP THE TROPICAL ACTIVITY OUT OF OUR
AREA. THE FORECAST THEN STARTS TO LOOK A LITTLE MORE TYPICAL OF
SUMMER...WITH TEMPERATURES WARMING TOWARD THE 90S AND POPS
DECREASING TO 20 OR 30 PERCENT. ONE NOTEWORTHY UPPER TROUGH IS
FORECAST TO ARRIVE MONDAY INTO EARLY TUESDAY...WHEN THUNDERSTORMS
MAY BECOME MORE ORGANIZED. THE GFS WAS PREFERRED IN THE FAR
EXTENDED...WHERE THE ECMWF SEEMS TOO PROGRESSIVE AND STRONG WITH
SOME OF ITS HIGH LATITUDE SYSTEMS...AND GFS FITS BETTER WITH THE
RECENT PATTERN. THE GFS AGAIN PROPS UP A RIDGE TO OUR EAST WHILE A
NEW TROUGH DROPS INTO THE PERSISTENT WEAKNESS TO OUR WEST. THAT
COULD AGAIN SET THE STAGE FOR MOIST FLOW UP FROM THE GULF BY LATE
NEXT WEEK...BUT CONFIDENCE IS FAIRLY LOW THAT FAR OUT.

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.
.DAY ONE...THIS AFTERNOON AND TONIGHT...
THUNDERSTORM OUTLOOK...
SEVERE THUNDERSTORMS ARE NOT EXPECTED.
DISCUSSION...
A DEEP LAYER OF MOIST AIR LOCATED OVER MUCH OF THE SOUTHERN
PLAINS... COMBINED WITH A WEAK COLD FRONT MOVING THROUGH THE
REGION... WILL RESULT IN A CONTINUATION OF SHOWERS AND THUNDERSTORMS
THROUGH TONIGHT. A RELATIVELY WEAK WIND SHEAR PATTERN WILL LIMIT THE
CHANCE FOR SEVERE STORMS. A FEW THUNDERSTORMS MAY PRODUCE BRIEF
STRONG WINDS TO 50 MPH THIS AFTERNOON AND EARLY EVENING. THE PRIMARY
THREAT FROM THE SHOWERS AND THUNDERSTORMS WILL CONTINUE TO BE HEAVY
RAINFALL.
PROBABILITY TABLE...
VALID THROUGH 700 AM CDT FRIDAY JUL 9.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...80 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...10 PERCENT.
OTHER HAZARDOUS WEATHER...
THE PERSISTENT...DEEP MOISTURE IN THE ATMOSPHERE... AND THE SLOW
MOVEMENT OF THE SHOWERS AND THUNDERSTORMS... WILL AGAIN SUPPORT
LOCALLY HEAVY RAINFALL. A WEAK UPPER LEVEL CIRCULATION OVER EAST
CENTRAL OKLAHOMA WILL GENERATE SHOWERS AND ISOLATED THUNDERSTORMS
THIS MORNING... WITH HEAVIEST RAINS BEING GENERALLY NORTH OF
INTERSTATE 40 AND ALONG AND EAST OF INTERSTATE 35. ELSEWHERE... A
WEAK COLD FRONT OVER NORTHERN OKLAHOMA THIS MORNING WILL MOVE SLOWLY
SOUTH DURING THE DAY. LOCALLY HEAVY RAINFALL WILL BE POSSIBLE MAINLY
NEAR AND SOUTH OF THE FRONT. BY THIS EVENING... THE MAIN THREAT AREA
FOR HEAVY RAIN WILL LIKELY BE ACROSS THE SOUTHERN HALF OF OKLAHOMA
INTO WESTERN NORTH TEXAS AS THE COLD FRONT CONTINUES TO SLIP SOUTH.
SEE THE FLASH FLOOD WATCH PRODUCT FOR FURTHER DETAILS.
.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...
THUNDERSTORM OUTLOOK...
ONGOING SHOWER AND THUNDERSTORM ACTIVITY FRIDAY MORNING WILL
MAINTAIN THE POTENTIAL FOR HEAVY RAIN AND FLOODING MAINLY OVER
SOUTHERN OKLAHOMA AND WESTERN NORTH TEXAS. ALTHOUGH RAIN CHANCES
WILL DECREASE BY FRIDAY NIGHT... THERE WILL BE AT LEAST A SLIGHT
CHANCE FOR THUNDERSTORMS OVER PORTIONS OF THE AREA THROUGH
WEDNESDAY.
OTHER HAZARDOUS WEATHER...
NONE.
THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED BY NOON
TODAY.
