The episode as NWS GID wrote it up.
For the second evening in a row, parts of western Dawson County were pounded by an isolated severe thunderstorm. On this early Sunday evening, the outflow-dominant supercell rolled in from the west-northwest, evolving from a cluster of storms that had been working toward the area from West Central Nebraska for a few hours. This storm flourished in a synoptic environment featuring subtle mid level disturbances passing through a west-northwest flow aloft, around 2000 J/kg MLCAPE and around 40 knots of deep-layer vertical wind shear. As the supercell first entered the far northwest corner of Dawson County, a trained spotter's home weather station recorded a powerful 94 MPH wind gust. Although the intensity of winds diminished as the storm moved deeper into the county, hail up to quarter size was reported farther east toward the Lexington area.

NWS Hastings, NE wrote its last area forecast discussion before the first event at Jul 11, 6:14 PM CST, 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 714 PM CDT SUN JUL 11 2010 .DISCUSSION...UPDATED THE FORECAST TO ACCOUNT FOR THE LATEST GROUP OF THUNDERSTORMS MOVING INTO THE WESTERN CWA. ADJUSTED WEATHER...CHANCES OF PRECIPITATION...SKY COVER...AND QPF ACCORDINGLY. && .PREV DISCUSSION... /ISSUED 620 PM CDT SUN JUL 11 2010/ AVIATION...00Z TAF. BIGGEST CHALLENGE WILL BE CHANCES AND TIMING OF THUNDERSTORM ACTIVITY TONIGHT. THERE COULD BE TWO ROUNDS OF STORMS TONIGHT...WITH THE FIRST BEING A BIT MORE IFFY. SOME ACTIVITY OFF TO THE NORTHWEST IS MOVING SOUTHEAST...AND WILL PROBABLY MISS THE TERMINAL JUST TO THE WEST...SO WILL LEAVE OUT OF THE FORECAST. AN MCS IS FORECAST TO MOVE INTO THE AREA OVERNIGHT AND THE CHANCES OF THIS OCCURRING SEEMS MUCH BETTER. VISIBILITY WILL LIKELY MOSTLY BE DICTATED BY THUNDERSTORM ACTIVITY...BUT MODELS ARE INDICATING GENERAL MVFR LATE TONIGHT INTO MONDAY MORNING. WIND SHOULD REMAIN RELATIVELY LIGHT...EXCEPT FOR SOME THUNDERSTORMS POSSIBLY PRODUCING SOME GUSTY WINDS. PREV DISCUSSION... /ISSUED 329 PM CDT SUN JUL 11 2010/ SHORT TERM...TONIGHT THROUGH 12Z TUESDAY. MAIN FORECAST CONCERNS WILL BE CHANCES FOR THUNDERSTORMS AND TEMPERATURES. A STUBBORN PATCH OF CLOUDS CONTINUES TO LINGER OVER CENTRAL NEBRASKA EARLY THIS AFTERNOON AND IS SPREADING SOME TOWARDS THE SOUTHEAST. SURFACE ANALYSIS SHOWS THAT THE FRONT IS THROUGH THE FORECAST AREA ALREADY THIS AFTERNOON. THE FRONT IS EXPECTED TO CONTINUE TO MOVE TO THE SOUTHEAST TONIGHT. ANOTHER UPPER LEVEL WAVE IS EXPECTED TO MOVE INTO THE AREA LATER TONIGHT. EXPECT THUNDERSTORMS TO DEVELOP THIS EVENING ON THE HIGH PLAINS AND MOVE INTO THE AREA TONIGHT. SOME COULD MOVE INTO THE AREA DURING THE EVENING BUT EXPECT MOST TO BE AFTER MIDNIGHT. THE BEST MUCAPE IS IN THE NORTHERN PART OF THE FORECAST AREA AND THE UPPER WAVE IS BEST IN THE NORTH SO HAVE KEPT THE BEST CHANCES FOR THUNDERSTORMS FURTHER NORTH. EXPECT SHOWERS AND THUNDERSTORMS TO CONTINUE INTO MONDAY. THE MAIN UPPER TROUGH WILL MOVE THROUGH THE FORECAST AREA ON MONDAY AND UNTIL THE TROUGH IS THROUGH EXPECT THERE COULD BE SOME PRECIPITATION AROUND. WITH THE CLOUDS AND PRECIPITATION TOMORROW AND COOLER AIR ACROSS THE AREA EXPECT TEMPERATURES TO BE COOLER FOR TOMORROW. HIGHS ONLY AROUND 80 DEGREES ARE POSSIBLE ACROSS THE AREA. BY MONDAY NIGHT THE UPPER WAVE IS MOVING OUT OF THE AREA AND WITH IT THE CHANCES FOR THUNDERSTORMS DIMINISH. THERE COULD BE SOME SHOWERS AND THUNDERSTORMS BUT THEY SHOULD BE MOSTLY IN THE EVENING BEFORE DIMINISHING LATE MONDAY NIGHT. LONG TERM...12Z TUESDAY THROUGH SUNDAY. NORTHWEST FLOW ALOFT ON TUESDAY WILL BECOME MORE WESTERLY ON WEDNESDAY AS AN UPPER LOW MOVES ACROSS SASKATCHEWAN INTO MANITOBA. THE 12Z NAM AND GFS HAVE CHANGED THEIR SOLUTIONS A BIT FOR TUESDAY IN THAT THEY PREVIOUSLY INDICATED A WEAK SURFACE BOUNDARY MOVING ACROSS THE CENTRAL PLAINS...BUT NOW THEY GENERALLY KEEP ANY SUCH BOUNDARY WEST OF THE FORECAST AREA. IN THE END...THIS DOES NOT REALLY CHANGE MUCH IN REGARDS TO THE FORECAST FOR TUESDAY WITH DRY WEATHER STILL EXPECTED ALONG WITH HOT TEMPERATURES. H85 TEMPERATURES WILL RANGE FROM +22 IN THE EAST...TO +28 IN THE WEST WHICH WILL BRING HIGHS INTO THE 90S OVER MOST OF THE FORECAST AREA. THE LOW MOVING THROUGH NORTH OF THE DAKOTAS WILL HELP BRING A FRONTAL BOUNDARY ACROSS THE CENTRAL AND NORTHERN PLAINS ON WEDNESDAY. THE TIMING OF THE BOUNDARY APPEARS TO BE A LITTLE FASTER IN THE 12Z NAM/GFS. BOTH MODELS NOW TAKE THE FRONT ACROSS THE FORECAST AREA BY MID TO LATE AFTERNOON...AND THEN STALL IT ACROSS CENTRAL KANSAS BY LATE WEDNESDAY NIGHT. IF THE FASTER TIMING DOES INDEED PAN OUT...THAT SHOULD LIMIT THE THUNDERSTORM CHANCES TO THE SOUTHERN PORTION OF THE CWA FOR WEDNESDAY AFTERNOON/NIGHT. WILL PUT THE HIGHER CHANCES OF THUNDERSTORMS ACROSS NORTH CENTRAL KANSAS....AND THEN DECREASE THE CHANCES FARTHER NORTH. THE BOUNDARY REMAINS JUST SOUTH OF THE FORECAST AREA THURSDAY MORNING...BUT LIFTS BACK NORTH DURING THE DAY INTO THE NIGHT. THIS SHOULD AGAIN KEEP THE HIGHER CHANCES OF THUNDERSTORMS CONFINED TO SOUTHERN SECTIONS OF THE CWA. CONFIDENCE BEGINS TO WANE TOWARDS NEXT WEEKEND WITH LESS AGREEMENT AMONGST THE GFS/ECMWF DETERMINISTIC SOLUTIONS. CURRENTLY THE 12Z GFS IS MUCH DRIER THAN THE 00Z ECMWF...AND GEFS POPS ARE NEAR OR JUST BELOW CLIMATOLOGY...SO HAVE GENERALLY OPTED TO GO WITH A DRIER APPEARANCE TO THE FORECAST FOR NOW. AM STILL A BIT CONCERNED THAT THERE COULD BE A FEW STORMS DURING THE NIGHT TIME HOURS ON SATURDAY...BUT WITH SUCH LOW CONFIDENCE DECIDED IT WAS BETTER TO GO WITH A SILENT 14 POP FOR NOW. && .GID WATCHES/WARNINGS/ADVISORIES...
