What happened

The episode as NWS OUN wrote it up.

An upper level low pressure anchored itself over central Oklahoma on the 2nd. Deep southerly flow brought in abundant moisture over the eastern half of Oklahoma. Disturbances rotating around the low pressure allowed for thunderstorms to develop over much of southeast Oklahoma. Persistent thunderstorms over Atoka county meant a continued threat for flash flooding. Numerous roads were closed across the county due to the high water.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
232 AM CDT MON JUL 2 2007

.DISCUSSION...
FLASH FLOOD WATCH REMAINS EFFECTIVE TODAY FOR MUCH OF CENTRAL AND
SOUTHERN OKLAHOMA AND ADJACENT PARTS OF WESTERN NORTH TEXAS AND
TONIGHT FOR AREAS NEAR AND SOUTH OF THE RED RIVER. AS THE UPPER
LOW DRIFTS SLOWLY SOUTHWEST INTO NORTH TEXAS LATER TODAY, THE WEAK
PREVAILING FLOW OVER THE WATCH AREAS WILL BE FROM THE SOUTH. THIS
WILL INTERACT WITH THE FRONT THAT IS DRIFTING SLOWLY SOUTH THROUGH
CENTRAL AND SOUTHWEST OKLAHOMA. HEATING TODAY NEAR THIS SURFACE
BOUNDARY WILL GIVE RISE TO MORE SHOWERS. TONIGHT A MODEST BOUNDARY
LAYER FLOW FROM THE SOUTH WILL LIFT OVER THE NEARLY-STALLED
SURFACE FRONT IN SOUTHERN OKLAHOMA OR NORTH TEXAS. THIS MAY GIVE
RISE TO SUSTAINED SHOWERS AND THUNDERSTORMS.

BY TUESDAY THE UPPER LOW IS EXPECTED TO BE EVEN FURTHER SOUTH AND
POPS ARE LOWER ACROSS MUCH OF OKLAHOMA, ESPECIALLY THE NORTH. WEAK
NORTHERLY FLOW ESTABLISHES ITSELF BY MID-WEEK AROUND THE GREAT
BASIN UPPER RIDGE. LATER WEDNESDAY OR THURSDAY, A COLD FRONT IS
STILL EXPECTED TO MOVE ACROSS THE STATE GIVING A TEMPORARY RISE IN
RAIN CHANCES. ONCE THIS FRONT AND ASSOCIATED TROUGH ARE AWAY, THE
FORECAST BECOMES DRIER INTO THE WEEKEND.
