A large upper level storm system located over over the southwest United States slowly pushed east. A disturbance moved from south to north over Oklahoma, creating enough lift for thunderstorms to develop over the northern half of Oklahoma.

The episode as NWS OUN wrote it up.
A large upper level storm system located over over the southwest United States slowly pushed east. A disturbance moved from south to north over Oklahoma, creating enough lift for thunderstorms to develop over the northern half of Oklahoma. One storm over Garfield county became severe, with winds causing damage near Enid.
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 Jun 12, 6:57 PM CST, 43 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE NORMAN OK 757 PM CDT SAT JUN 12 2010 .UPDATE... SCATTERED SHOWERS/STORMS CONTINUE TO DEVELOP THIS EVENING IN NORTHERN OKLAHOMA. IT APPEARS NOW THAT STORMS IN THE PANHANDLES HAVE ENOUGH OF AN EASTERLY PUSH TO MOVE INTO NORTHWEST PORTIONS OF FA THIS EVENING SO HAVE INCREASED POPS. SOME OF THESE STORMS MAY BE SEVERE WHEN THEY MOVE INTO THE FA. LOCALLY HEAVY RAIN MAY ALSO BE AN ISSUE WITH THE STORMS. ADDITIONAL STORMS IN NORTHERN PORTIONS OF THE FA MAY BE POSSIBLE OVERNIGHT... ESPECIALLY IF AN OUTFLOW BOUNDARY IS IN THE AREA FROM THIS EVENINGS STORMS AND THE LLJ INTERACTS WITH THIS BOUNDARY. WILL SEND UPDATES SHORTLY. MAXWELL && .PREV DISCUSSION... /ISSUED 615 PM CDT SAT JUN 12 2010/ AVIATION... STRONG/SEVERE STORMS WEST-NORTH OF KWWR/KGAG ARE BEGINNING TO SHOW SIGNS OF TRYING TO PUSH EAST AT THIS TYPING...BUT MAJORITY OF CONVECTION WILL LIKELY STAY NORTH OF THOSE TERMINALS. HOWEVER...WE WILL INCLUDE A TEMPO GROUP THIS EVENING FOR KGAG/KWWR. OTHER ISOLATED/SCATTERED SHOWERS AND WEAKER STORMS OVER THE BODY OF OKLAHOMA EXPECTED TO MISS NORTHERN OKLAHOMA TERMINALS...STAYING BETWEEN KWWR AND KPNC. AREAS OF MVFR CEILINGS ONCE AGAIN EXPECTED LATE TONIGHT AND TOMORROW MORNING...BEFORE LIFTING TO VFR TOWARD AND AFTER 17Z. WILL INCLUDE TEMPO TSRA AT KGAG/KWWR TOMORROW AFTERNOON AND PROB30 AT KPNC/KCSM DUE TO PROXIMITY OF SLOW MOVING COLD FRONT THAT WILL MAKE ITS WAY ACROSS THE REGION THE NEXT FEW DAYS. DISCUSSION... LARGE UPPER TROUGH OVER THE SOUTHWEST US STILL OUR MAIN WEATHER MAKER FOR THE NEXT FEW DAYS. SOUTHWESTERLY FLOW ALOFT... COMBINED WITH A WELL DEFINED SURFACE COLD FRONT WILL CREATE SEVERAL CHANCES FOR THUNDERSTORMS OVER MUCH OF THE AREA. THE COLD FRONT MADE A GOOD RUN TOWARD NORTHWEST OKLAHOMA OVERNIGHT... BUT HAS NEARLY STALLED OVER SOUTHWEST KANSAS INTO THE NORTHWEST TEXAS PANHANDLE. THUNDERSTORMS HAVE BEGUN TO DEVELOP NEAR AND TO THE NORTH OF THE BOUNDARY... AND FURTHER DEVELOPMENT IS LIKELY THROUGH THIS EVENING. MUCH OF THE ACTIVITY... AT LEAST INITIALLY... WILL REMAIN WEST OF OUR BORDER. HOWEVER... NORTHEAST STORM MOTIONS SHOULD BRING THUNDERSTORMS NEAR OR OVER OUR NORTHWEST COUNTIES. WILL HAVE TO WATCH THE STRENGTH OF THE THUNDERSTORMS AS WELL... AS FLOW ALOFT IS MORE THAN SUFFICIENT FOR SEVERE STORMS... AND INSTABILITY IS MAXIMIZED THERE. HIGHEST THUNDERSTORM CHANCES FOR SUNDAY WILL BE DEPENDENT ON WHERE THE FRONT ENDS UP TONIGHT. OVERNIGHT ACTIVITY WILL LIKELY PUSH THE FRONT SOUTHEAST TO SOME EXTENT. HIGHEST POPS WILL REMAIN NEAR THE FRONT ON SUNDAY... WITH A SIMILAR SITUATION THAN WHAT WE ARE EXPERIENCING TODAY. THE FRONT SHOULD FINALLY START MOVING MORE INTO OKLAHOMA... AND WILL LIKELY BE MOST OF THE WAY THROUGH OUR CWA BY MONDAY EVENING... AS THE UPPER TROUGH OPENS UP AND LIFTS TOWARD THE NORTHEAST. WE ALSO HAVE CONCERNS FOR HEAVY RAINFALL WITH ANY THUNDERSTORM. PRECIPITABLE WATER VALUES ARE CLOSE TO TWO INCHES IN SOME SPOTS... AND THE UPPER FLOW SHOULD PARALLEL THROUGH COLD FRONT THROUGH THE EVENT... FAVORING TRAINING THUNDERSTORMS. EVEN AFTER THE FRONT PASSES... BOTH THE NAM AND GFS ARE PLACING AN AXIS OF HEAVY RAINFALL AT THE ENTRANCE REGION OF THE UPPER JET. PARTS OF THE CWA HAVE NOT SEEN RAINFALL IN SEVERAL DAYS... SO ANY RAINFALL WILL BE BENEFICIAL. SOME SPOTS MAY RECEIVE A COUPLE OF INCHES OF RAINFALL BEFORE IT IS ALL SAID AND DONE. WARM AND MUGGY CONDITIONS WILL CONTINUE UNTIL THE COLD FRONT PASSES . HOWEVER... LOOKS LIKE THE RIDGE WILL TRY AND BUILD BACK IN BY MID WEEK... BRINGING TEMPERATURES BACK TO NEAR OR JUST ABOVE NORMAL. NO CHANGES MADE TO THE EXTENDED. && .PRELIMINARY POINT TEMPS/POPS...
