What happened
The episode as NWS OUN wrote it up.
Thunderstorms developed ahead of a weak cold front that moved into parts of western Oklahoma. The storms were mainly driven by strong afternoon heating, and aided by a weak upper level disturbance. Wind gusts to 50 mph and very heavy rainfall were the main threats, although a couple of storms briefly produced severe wind gusts over 60 mph. No damage was reported with the thunderstorms.

Area forecast discussion, Jul 31, 5:37 PM CST, 11 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 637 PM CDT SAT JUL 31 2010 .AVIATION... VFR WITH PREVAILING SCT CLOUDS GENERALLY 6-8K FT. SHRA/TSRA MOST NUMEROUS IN THE KCSM AREA AND PERHAPS INTO KHBR FOR A COUPLE HRS THIS EVENING... OTHERWISE CONVECTION TOO ISOLATED TO MENTION IN TAFS. DEWPOINT DEPRESSIONS APPROACHING 40F NEAR THE CURRENT CONVECTION... SO THERE WILL BE SOME MICROBURST POTENTIAL THIS EVENING. && .PREV DISCUSSION... /ISSUED 254 PM CDT SAT JUL 31 2010/ DISCUSSION... A WEAK FRONT/OUTFLOW BOUNDARY HAS DRIFTED INTO OK... ALTHOUGH ITS EXACT LOCATION IS RATHER ILL-DEFINED DUE TO SURFACE WINDS BACKING AHEAD OF THE FRONT IN CENTRAL OK. A FEW SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE THROUGH THE REMAINDER OF THE AFTERNOON AND THIS EVENING. AFTERNOON SATELLITE WAS INDICATING A COUPLE OF AREAS OF ENHANCED CU FIELDS... ACROSS NORTH CENTRAL OK... FROM THE NORTHEAST TX PANHANDLE EXTENDING INTO SOUTHWEST OK... AND NEAR AND JUST SOUTH OF THE RED RIVER. THESE AREAS... MOST OF WHICH ALSO COINCIDE WITH WEAK LOW LEVEL MOISTURE CONVERGENCE FIELDS... WILL LIKELY BE THE THE MOST FAVORABLE LOCATIONS FOR INITIAL SHOWER/STORM DEVELOPMENT. THE LACK OF ANY SIGNIFICANT UPPER SUPPORT... ALONG WITH THE PRESENCE OF THE UPPER RIDGE CENTERED OVER THE WESTERN PART OF THE AREA THIS AFTERNOON... WILL LIKELY PRECLUDE MORE WIDESPREAD DEVELOPMENT. DRY WEATHER IS EXPECTED FOR SUNDAY AS THE FRONT FURTHER WEAKENS WHILE MOVING BACK NORTH. HOWEVER... A REMOTE POSSIBILITY FOR AN ISOLATED SHOWER OR TWO WILL CONTINUE OVER NW OKLAHOMA. THE UPPER RIDGE IS FORECAST TO SHIFT SLOWLY TO THE EAST OVER THE NEXT COUPLE OF DAYS... BECOMING CENTERED OVER EASTERN ARKANSAS BY MONDAY. MEANWHILE... THE NAM... GFS... AND TO SOME EXTENT THE ECMWF... ARE INDICATING THAT A WEAK UPPER LEVEL EASTERLY WAVE... MOVING WEST AROUND THE UPPER RIDGE... WILL TURN MORE TO THE NORTHWEST AND MOVE ACROSS THE WESTERN PORTION OF THE AREA ON MONDAY. HOWEVER... THE MODELS ALSO AGREE IN VEERING THE LOW LEVEL FLOW MORE TO THE SOUTHWEST AND DECREASING THE AMOUNT OF LOW LEVEL MOISTURE. GIVEN THE WEAKNESS OF THIS FEATURE... AND THE EXPECTED LOW-LEVEL DRYING... WE WILL NOT INTRODUCE POPS FOR MONDAY ATTM. OKLAHOMA MESONET AT MID AFTERNOON INDICATES A FEW LOCATIONS WITH HEAT INDEX VALUES REACHING 105... WHILE MOST OF THE AREA HAD VALUES IN THE UPPER 90S TO NEAR 102. IT APPEARS THAT THE COMBINATION OF THE HOT TEMPERATURES AND RELATIVELY HIGH DEWPOINTS IN THE LOWER 70S COULD PUSH HEAT INDEX VALUES TO NEAR 105 IN SOME AREAS ON SUNDAY. WHILE THE HEAT WILL CONTINUE INTO MONDAY... THE HEAT INDEX VALUES ARE FORECAST TO FALL BY SEVERAL DEGREES ON MONDAY DUE TO THE SOMEWHAT DRIER AIR MOVING INTO THE REGION. FEW CHANGES MADE TO THE EXTENDED PERIODS. THE OPERATIONAL GFS... AND TO SOME EXTENT THE ECMWF... ARE BACKING OFF ON THEIR EFFORTS TO BRING ANOTHER FRONT INTO OKLAHOMA AROUND THE MIDDLE OF NEXT WEEK... WHILE THE GFS ENSEMBLE MEAN REMAINS MORE OPTIMISTIC. GIVEN WE HAVE ONLY LOW POPS ACROSS THE NORTH... WILL LEAVE THOSE BE FOR NOW. NO MAJOR TEMPERATURE CHANGES EXPECTED THROUGH MUCH OF NEXT WEEK ACROSS THE AREA WITH AFTERNOON HIGHS GENERALLY WITHIN A FEW DEGREES EITHER SIDE OF THE CENTURY MARK. && .PRELIMINARY POINT TEMPS/POPS...
