The episode as NWS LBF wrote it up.
A surface trough extended south through central Nebraska and became the focus for severe thunderstorms by mid afternoon. A disturbance lifted east from Wyoming across central South Dakota and provided lift in addition to jet dynamics that increased shear for supercell thunderstorm development. The severe thunderstorms produced large hail up to 2 inches, damaging winds and heavy rainfall.

NWS North Platte, NE wrote its last area forecast discussion before the first event at Aug 8, 2:37 AM CST, 10 hours 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTH PLATTE NE 337 AM CDT SUN AUG 8 2010 .DISCUSSION... TSTM CHANCES AND THE HEAT REMAIN THE CONCERN FOR THE NEXT FEW DAYS. THE HEAT ADVISORY WILL REMAIN IN EFFECT TODAY FOR AREAS EAST OF A NORTH PLATTE TO BASSETT LINE. TEMPERATURES WILL APPROACH THE MID 90S THIS AFTERNOON...AS LIGHT SOUTHEAST WINDS ALLOW MOISTURE TO POOL ALONG AND SOUTHEAST OF A SURFACE TROUGH THAT WILL EXTEND FROM ROUGHLY IMPERIAL TO AINSWORTH BY LATE AFTERNOON. DEW POINTS TO THE EAST OF THE SURFACE TROUGH WILL REMAIN IN THE 70S...AND WHEN COMBINED WITH TEMPERATURES IN THE MID 90S...HEAT INDEXES WILL PUSH INTO THE 105 TO 110 DEGREE RANGE. NEXT CONCERN WILL BE THE THREAT FOR TSTMS AND HEAVY RAIN...AS WELL AS SEVERE WEATHER LATE THIS AFTERNOON AND TONIGHT. SPC HAS MOST OF THE AREA INCLUDED IN A SLIGHT RISK FOR SEVERE TSTMS TODAY AND TONIGHT...AND AGREE WITH THIS BASED ON 0-6 KM BULK SHEAR...CAPE...AND LOW LEVEL LAPSE RATES. WE ALSO HAVE A SFC TROUGH TO FOCUS CONVECTION RIGHT THROUGH THE HEART OF THE FORECAST AREA. COMBINE ALL OF THIS WITH DECENT UPPER LEVEL SUPPORT...AND TSTMS ARE A GOOD POSSIBILITY. INCREASED POPS TO 30 PERCENT THIS AFTERNOON INVOF OF SFC TROUGH...AND WENT LIKELY ACROSS THE CENTRAL AND NORTHEAST TONIGHT. HEAVY RAIN POTENTIAL IS SUPPORTED BY HIGH K INDEX VALUES...AND PWAT/S APPROACHING 2 INCHES. MORE OF THE SAME MONDAY...WITH THE HEAT AND HUMIDITY CONTINUING ALONG WITH TSTM CHANCES. MODELS AGREE THAT A WARM FRONT WILL DEVELOP NEAR THE I-80 CORRIDOR BY AFTERNOON...WITH HIGH DEW POINTS /MID 70S/ POOLING JUST NORTH OF THE BOUNDARY. THIS MOISTURE WILL LEAD TO VERY UNSTABLE CONDITIONS...AND TSTMS WILL LIKELY RESULT BY LATE AFTERNOON. THE I-80 CORRIDOR AND POINTS JUST NORTH STAND THE BEST CHANCE FOR HEAVY RAIN AND SEVERE STORMS MONDAY EVENING. THROUGH THE REMAINDER OF THE WEEK...GFS INDICATES INSTABILITY WILL REMAIN ALONG WITH INCREASED SHEAR PROFILES...AND AT LEAST ISOLATED TSTMS ARE POSSIBLE. VERY WARM AND RATHER HUMID CONDITIONS WILL ALSO PERSIST. && .AVIATION...

CEILINGS AON 15000 FT AGL...THIS MORNING...WILL DROP TO 10000 FT THIS AFTERNOON. AT THE KLBF TERMINAL...SCATTERED THUNDERSTORMS ARE POSSIBLE AFTER 21Z AND THE THREAT WILL CONTINUE THROUGH 03Z THIS EVENING. WILL HANDLE TSRAS WITH A PROB30 GROUP ATTM...AS CONVECTION WILL BE HIGHLY DEPENDENT ON THE LOCATION OF A SURFACE FRONTAL BOUNDARY. AT THIS TIME...THE BOUNDARY IS EXPECTED TO BE IN THE VICINITY OF KLBF AND EAST OF THE KVTN TERMINAL. FOR THAT REASON...WILL LEAVE OUT MENTION OF TS IN THE KVTN TAF THIS ISSUANCE AS TS COVERAGE WILL BE ISOLATED BEHIND THE FRONT. WEST OF THE FRONTAL BOUNDARY TONIGHT...THE THREAT WILL EXIST FOR FOG FORMATION...ESPECIALLY IN AREAS WHERE PRECIPITATION FALLS LATER TODAY. ATTM THE THREAT FOR FOG IS HIGHEST AT THE KVTN TERMINAL BUT NOT ENOUGH CONFIDENCE EXISTS ATTM TO PUT IN THE 12Z TAF FCST. && .LBF WATCHES/WARNINGS/ADVISORIES...HEAT ADVISORY FROM NOON CDT TODAY TILL 800 PM CDT TONIGHT FOR NEZ007-009>010-026>029-038-059-071. && DISCUSSION...TAYLOR AVIATION...BUTTLER
