The episode as NWS AMA wrote it up.
Severe thunderstorms in the central and eastern Oklahoma Panhandle produced wind damage and hail along with isolated flash flooding during the early evening hours. The high winds caused power outages across the Tri-County Electric Cooperative service area with approximately one thousand and seven hundred members without power during the storms. Downed power poles caused the longest outages in Turpin Oklahoma and on the northeast edge of Guymon Oklahoma. No injuries were reported.

NWS Amarillo, TX wrote its last area forecast discussion before the first event at Jul 12, 2:45 PM CST, 2 hours earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 345 PM CDT THU JUL 12 2007 .DISCUSSION... DIFFICULT FORECAST THIS EVENING AS MULTIPLE FACTORS ARE COMING INTO PLAY ACROSS THE PANHANDLES. FIRST ISSUE WILL BE AN MCV THAT IS ROTATING UP FROM SOUTHEASTERN NEW MEXICO TOWARDS THE AREA THAT IS HELPING TO SPARK STORMS ACROSS THE SOUTH PLAINS. THIS MIGHT HELP AN INITIAL ROUND OF CONVECTION TO DEVELOP ACROSS THE SOUTHWESTERN PORTIONS OF THE FORECAST AREA. SECOND ISSUE WILL BE A SHORTWAVE MOVING AROUND THE RIDGE AND SLIDING ACROSS THE AREA LATE TONIGHT INTO TOMORROW MORNING. WHETHER OR NOT OUTFLOW BOUNDARIES FROM THE ACTIVITY THIS AFTERNOON OR EVENING WILL HURT OR HELP THE EXPECTED DEVELOPMENT OF AN MCS WILL HAVE TO BE SEEN. NEXT IS THE COLD FRONT CURRENTLY PUSHING INTO NEBRASKA THAT COULD ALSO HELP TO GET THUNDERSTORMS INITIATED ACROSS COLORADO THAT WILL DROP INTO THE AREA. TOPPING THINGS OFF IS A VERY MOIST ATMOSPHERE AS ANALYSIS OF THE 12Z UPPER-AIR DATA SHOWS DEEP MOISTURE ROTATING ACROSS THE REGION AT 850 AND 700 HPA THANKS TO AN AREA OF HIGH PRESSURE ALONG THE TEXAS GULF COAST. WITH ALL THESE THINGS IN MIND...WILL LIKELY SEE ISOLATED TO WIDELY SCATTERED SHOWERS AND STORMS CONTINUE THROUGH THE AFTERNOON AND EARLY EVENING HOURS THANKS TO AN UNSTABLE ATMOSPHERE AND LIFT FROM THE NEW MEXICO MCV. HIGHEST POP CHANCES HOWEVER HINGE ON THE SHORTWAVE INITIATING STORMS TO THE NORTHWEST OF THE AREA AND THESE PUSHING ACROSS THE AREA LATE TONIGHT INTO EARLY TOMORROW MORNING. TOYED WITH THE IDEA OF ISSUING A FLASH FLOOD WATCH FOR THE NORTHEASTERN PANHANDLES AS MODELS ARE SPITTING OUT QUITE A BIT OF PRECIPITATION. FEEL THAT STORMS SHOULD BE MOVING FAST ENOUGH...AREAS OF HEAVIEST RAINFALL WILL BE LOCALIZED... AND LACK OF RECENT HEAVY RAINFALL WILL PRECLUDE WIDESPREAD FLASH FLOODING. HOWEVER...WOULD NOT BE SURPRISED TO SEE SOME AREAS NORTH AND EAST OF A GOODWELL TO MIAMI LINE RECEIVE 2-4 INCHES OF RAINFALL /IF/ THE MCS DEVELOPS. MCV OVER NEW MEXICO COULD THROW A WRENCH INTO THINGS BUT FEEL THAT THE STRENGTH OF THE SHORTWAVE WILL HELP TO OVERCOME ANY INFLUENCES THE MCV MIGHT HAVE. HAVE ALSO CONTINUED SEVERE WORDING AS INITIAL STAGES OF THE MCS COULD HAVE HAIL AND WIND BUT AS COLD POOL BECOMES ORGANIZED AND MCS MATURES...DAMAGING WIND THREAT WILL BECOME DOMINANT. TRAILING EDGE OF MCS COULD LINGER ACROSS THE SOUTHEASTERN TEXAS PANHANDLE BY SUNRISE TOMORROW AND HAVE LEFT CHANCE POPS IN ACROSS THIS AREA. COLD FRONT WILL LIKELY BECOME MASKED BY THE OUTFLOW FROM THE MCS AND HAVE PRETTY MUCH KEPT WINDS OUT OF THE EAST TOMORROW AFTERNOON INDICATING A POST-FRONTAL AIRMASS. PRECIP CHANCES LOOK TO BE SLIM RIGHT NOW FOR ALL BUT THE FAR SOUTHEAST TEXAS PANHANDLE FOR TOMORROW NIGHT THANKS TO A SOMEWHAT MORE STABLE AIRMASS IN PLACE. HAVE ALSO GONE WITH SLIGHT CHANCE POPS FOR SATURDAY NIGHT AS MODELS ARE TRYING TO BRING ANOTHER FRONT DOWN THE PLAINS INTO THE REGION. WILL HAVE TO SEE IF THIS DEVELOPS OR NOT AS THE NAM IS BREAKING OUT A BIT OF PRECIP WHILE THE GFS REMAINS SOMEWHAT DRIER. REST OF THE FORECAST WAS LEFT INTACT AS MAJORITY OF TIME WAS SPENT TRYING TO FIGURE OUT WHAT THE FIRST 48 HOURS OF THE FORECAST WILL BRING. A QUICK GLANCE OF THE 12Z EXTENDED MODEL DATA SHOWS THAT THE RIDGE TRIES TO BUILD BACK OVER THE REGION WITH ANOTHER LOW TRYING TO DEVELOP AT 500 HPA ACROSS SOUTH TEXAS. LOCATION OF THIS LOW/SHEAR AXIS COULD HAVE AN INFLUENCE ON OUR WEATHER BUT DECIDED NOT TO MAKE ANY CHANGES TO THE EXTENDED FOR NOW. JORDAN && .PRELIMINARY POINT TEMPS/POPS...
