The episode as NWS OUN wrote it up.
Scattered thunderstorms, some severe, developed during the evening hours over much of western Oklahoma and western north Texas. Another cluster of thunderstorms developed further west into the Texas panhandle. This thunderstorm cluster moved into the western portions of northern Texas, with a bow echo moving through Hardeman county. Winds reached as high as 60 mph near the North Groesbeck community, but no damage was reported. The line continued to move east through the late evening, eventually reaching the Wichita Falls area. Winds here were measured near 60 mph.
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 Jul 29, 5:51 PM CST, 4 hours 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 651 PM CDT WED JUL 29 2009 .AVIATION... CONVECTION ACROSS EASTERN NEW MEXICO/SOUTHEAST COLORADO IS BECOMING BETTER ORGANIZED EARLY THIS EVENING...PER RADAR TRENDS...COOLING CLOUD TOPS. FOLLOWED CURRENT RUNS OF THE RAPID REFRESH MODEL FOR TIMING OF MCS LATE THIS EVENING/OVERNIGHT. DIFFICULT AT THIS TIME TO DETERMINE WHERE STRONGER STORMS WILL OCCUR...BUT EXPECT IFR VISIBILITIES AND CEILINGS WILL BE LIKELY WITH STRONGER CONVECTION. EXPECT MOST OF THE STRONGEST CONVECTION WITH BE CONFINED TO AREAS SOUTH AND EAST OF TAF SITES BY 12Z WITH LINGERING SHOWERS AND STORMS POSSIBLE WITH MVFR CEILINGS. && SIX .PREV DISCUSSION... /ISSUED 401 PM CDT WED JUL 29 2009/ DISCUSSION... A FEW SHOWERS AND T-STORMS WILL BE POSSIBLE LATE THIS AFTERNOON AND EARLY EVENING AS DAYTIME HEATING INCREASES THE INSTABILITY OF THE AIRMASS. HOWEVER... MORE ORGANIZED ACTIVITY IS EXPECTED TO MOVE ACROSS THE AREA DURING THE OVERNIGHT HOURS. A MODERATELY STRONG SHORT WAVE MOVING INTO THE CENTRAL PLAINS WILL HELP TO PUSH A COLD FRONT SOUTH INTO THE AREA TONIGHT. INCREASING UPSLOPE FLOW OVER SOUTHEAST COLORADO AND NORTHEAST NEW MEXICO HAS ALREADY RESULTED IN CONVECTION DEVELOPING IN THOSE AREAS. SOME OF THIS ACTIVITY IS EXPECTED TO MOVE SOUTHEAST INTO AT LEAST THE WESTERN PORTIONS OF THE CWA LATE TONIGHT AND EARLY THURSDAY. ADDITIONAL STORM DEVELOPMENT COULD ALSO OCCUR ALONG THE COLD FRONT AS IT MOVES ACROSS THAT AREA. LOCALLY HEAVY RAINFALL WILL BE POSSIBLE IN SOME AREAS ALTHOUGH UNCERTAINTY EXISTS CONCERNING FLASH FLOOD THREAT. PRECIPITABLE WATER AMOUNTS WILL APPROACH 2 INCHES IN PARTS OF SOUTH CENTRAL AND SOUTHEAST OKLAHOMA HOWEVER IT APPEARS THE MOST ACTIVE AREA OF CONVECTION... AHEAD OF THE CENTRAL TEXAS MCV... WILL STAY SOUTHEAST OF OUR CWA. ELSEWHERE... LOCALIZED AREAS OF HEAVY RAIN LAST NIGHT IN PARTS OF CENTRAL OKLAHOMA AND WESTERN NORTH TEXAS HAS RESULTED IN SOMEWHAT LOWER FLASH FLOOD GUIDANCE IN THOSE AREAS... BUT THE EXPECTED PROGRESSIVE MOVEMENT OF THUNDERSTORM CLUSTERS SHOULD LOWER THE LIKELIHOOD FOR WIDESPREAD HEAVY RAIN. COOLER AND SOMEWHAT DRIER AIR WILL SPREAD INTO THE AREA BEHIND THE COLD FRONT ON THURSDAY BEFORE TEMPERATURES START TO RECOVER TO NEAR SEASONAL LEVELS OVER THE SOUTH BY SATURDAY. NORTHWEST FLOW ALOFT WILL CONTINUE OVER THE SOUTHERN PLAINS INTO EARLY NEXT WEEK ALTHOUGH IT MAY WEAKEN SOMEWHAT BY THAT TIME. THIS PATTERN WILL CONTINUE TO PUSH OCCASIONAL FRONTS ACROSS THE AREA. && .PRELIMINARY POINT TEMPS/POPS...
