The episode as NWS OUN wrote it up.
Moist, tropical air remained in place over Oklahoma, with scattered showers and thunderstorms remaining a daily afternoon occurrence. A weak boundary stalled close to I-44 by early afternoon. The highest concentration of precipitation occurred near and southeast of this boundary, with intense rainfall rates of over two inches per hour reported at many locations. One location that received some of the heavier rainfall was south Oklahoma City. For the 2nd time in three days, a band of heavy rainfall set up over the southern portion of Oklahoma, causing a localized area of flash flooding. The rain lasted for 2 to 3 hours, and as much as 7 inches of rain was reported. Most of the roadways were quickly flooded. Creeks in the area flooded, flooding several homes with a few feet of water. The rainfall intensity and coverage decreased with the loss of daytime heating.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
238 PM CDT THU JUL 8 2010
.DISCUSSION...
MAIN CONCERN IN THIS FORECAST IS OBVIOUSLY THE RAIN. NUMEROUS
SHOWERS AND ISOLATED THUNDERSTORMS CONTINUE THIS AFTERNOON ACROSS
THE SOUTHEAST HALF OF OUR FORECAST AREA... WITH MORE ISOLATED
SHOWERS TO THE NORTHWEST. THE RAIN IS RE-FOCUSING ALONG A
STATIONARY WIND SHIFT LINE THAT IS NEARLY PARALLEL TO... AND ABOUT
ONE COUNTY SOUTHEAST OF... I-44. AS THE AFTERNOON AND EVENING
PROGRESS... THIS SHOULD REMAIN THE PRIMARY FOCUS LINE... BUT
OUTFLOW BOUNDARIES WILL ALSO FOCUS STORM DEVELOPMENT.
AS FOR THE FLASH FLOOD WATCH... WE WILL TRIM SOME OF THE NORTHERN
COUNTIES FROM THE WATCH THIS AFTERNOON. THE COMBINATION OF
ANTECEDENT RAINFALL AND EXPECTED RAINFALL OVER THE NEXT DAY OR SO
WAS THE PRIMARY CONSIDERATION FOR THE WATCH. FOR THE MOST PART...
THE HEAVIEST RAINFALL WILL LIKELY FALL OVER THE AREAS THAT CAN
MOST AFFORD THE RAIN. HOWEVER... GIVEN THE TROPICAL NATURE OF THE
RAIN... AND THE TORRENTIAL RAINFALL RATES... FLASH FLOODING WILL
REMAIN A POTENTIAL PROBLEM FOR THOSE COUNTIES STILL IN THE WATCH.
AT THIS TIME... IT APPEARS THAT THE COUNTIES MOST LIKELY TO
EXPERIENCE SIGNIFICANT FLOODING WILL BE OUR TEXAS COUNTIES... AND
THOSE FROM LOVE NORTHEAST TO COAL AND ATOKA. THE COUNTIES CLOSER
TO THE NORTHERN EDGE OF THE WATCH ARE LEAST LIKELY TO HAVE SERIOUS
FLOODING.
AS THE SURFACE CONVERGENCE WEAKENS FURTHER TOMORROW... AND AS THE
OVERALL WEATHER PATTERN BECOMES SOMEWHAT LESS FAVORABLE FOR
RAIN... THE RAIN CHANCES WILL BEGIN TO DIMINISH. HOWEVER... THEY
REALLY NEVER GO AWAY COMPLETELY THOUGH THE REMAINDER OF THE FORECAST
PERIOD.
OTHERWISE... MODIFICATIONS TO THE PREVIOUS FORECAST WERE MINIMAL.

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.
.DAY ONE...THROUGH 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...100 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 COLD FRONT OVER NORTHWEST OKLAHOMA
WILL MOVE SLOWLY SOUTH THIS AFTERNOON AND EVENING. 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 5 AM
FRIDAY.
