The episode as NWS OUN wrote it up.
Isolated thunderstorms with very heavy rainfall developed over parts of Oklahoma, including Garvin and Washita Counties, during the afternoon hours. The slow movement of the thunderstorms and an already saturated ground allowed for small-scale areas of flash flooding. Minor damage was reported with the flooding in Pauls Valley. Monetary damages were estimated.

NWS Norman, OK wrote its last area forecast discussion before the first event at Aug 1, 10:02 AM CST, 3 hours 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 1102 AM CDT WED AUG 1 2007 .DISCUSSION... FIRST WAVE OF CONVECTION IS CONTINUING TO MOVE SLOWLY SOUTHEAST ACROSS SOUTH CENTRAL OKLAHOMA AND NORTH CENTRAL TEXAS. THE COVERAGE AND INTENSITY HAS BEEN GENERALLY DECREASING THROUGH THE MID MORNING. BUT IT AGAIN LOOKS LIKE WE WILL SEE REDEVELOPMENT OF CONVECTION EARLY THIS AFTERNOON AS TEMPERATURES WARM AND SOUNDINGS SHOW AN UNCAPPED ATMOSPHERE. CURRENT FORECAST SEEMS TO HAVE THIS WELL IN HAND AND NO UPDATED NEEDED TO THE FORECAST. MAY ISSUE UPDATED ZONES EARLY THIS AFTERNOON TO REMOVE TEMPORAL WORDING...BUT NO SIGNIFICANT CHANGES PLANNED AT THE MOMENT. && .PREV DISCUSSION... /ISSUED 250 AM CDT WED AUG 1 2007/ DISCUSSION... BOTH THE NAM AND GFS INITIALIZE REASONABLY WELL WITH THE SHORTWAVE TROUGH OVER SOUTHWEST KANSAS AND ALSO THE NEARLY MOIST ADIABATIC LAPSE RATES THAT EXIST OVER THE AREA WITH THE 900 TO 850 MB BAROCLINIC ZONE EXTENDING FROM SOUTHEAST OKLAHOMA...NORTHWESTWARD TO NEAR WOODWARD. THE SURFACE REFLECTION OF THE FRONT IS DIFFICULT TO DISCERN...BUT APPEARS TO BE JUST SOUTH OF THE RED RIVER. THE GFS IS GIVEN THE EDGE WITH REGARD TO PRECIPITATION EARLY THIS MORNING DUE TO ITS BETTER PERFORMANCE WITH RECENT CONVECTIVE DEVELOPMENT OVER WESTERN OKLAHOMA BUT ALSO DURING PREVIOUS MORNINGS. OTHERWISE...THE NAM/GFS APPEAR SIMILAR IN TERMS OF KINEMATICS/THERMODYNAMICS. ALTHOUGH THE GFS FORECAST SOUNDINGS SEEM TO HAVE A DRY BIAS WITH PREFERENCE GIVEN TO THE NAM HERE. THE DEVELOPMENT PRECIPITATION OVER WESTERN OKLAHOMA IS WITHIN HIGHER BASED PORTIONS OF THE FRONTAL BOUNDARY...AND WITH THE LOW LEVEL JET ALREADY IN GEAR AND EXPECTED TO VEER TOWARD 12Z...WE EXPECT THE GFS IS ON TO SOMETHING WITH A SWATH OF SHOWERS AND THUNDERSTORMS WEST OF INTERSTATE 35 THIS MORNING. THIS ACTIVITY IS THEN EXPECTED TO RE-IGNITE ALONG OUTFLOW BOUNDARIES AND DIFFERENTIAL HEATING ZONES THIS AFTERNOON. THE LOWEST CHANCES FOR RAIN TODAY APPEAR TO BE ACROSS NORTH CENTRAL OKLAHOMA...WHICH MAY LACK A FOCUSING MECHANISM DESPITE THE WARM AND RELATIVELY UNCAPPED ENVIRONMENT. ANOTHER ROUND OF LATE NIGHT CONVECTION MAY DEVELOP ACROSS THE WEST AGAIN WEDNESDAY NIGHT. HOWEVER...MODEL TRENDS CONTINUE WITH A SLIGHTLY MORE SUBSIDENT REGIME BUILDING INTO NORTHERN OKLAHOMA DUE THE EXPANDING MID/UPPER HIGH. THEN BY FRIDAY....MOST IF NOT ALL RAIN CHANCES SHOULD BE SUPPRESSED BELOW 10 PERCENT WITH THE LEE ROCKIES SURFACE TROUGH RESULTING IN INCREASINGLY WARM AND WINDY CONDITIONS DEVELOPING BY NEXT WEEKEND. && .PRELIMINARY POINT TEMPS/POPS...
