The episode as NWS OAX wrote it up.
Scattered thunderstorms developed over northeast Nebraska during the late evening/early morning hours of August 1st and 2nd. The storms formed on the nose of a low level jet. An isolated storm east of Columbus produced wind damage, but the storms mainly dropped heavy rain with some locations around the Norfolk area receiving over 3 inches of rain.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 311 PM CDT SUN AUG 1 2010 .SHORT TERM...TONIGHT. THE MAIN CONCERN FOR TONIGHT WILL BE THE CHANCE FOR THUNDERSTORMS. SFC HIGH PRES WAS CENTERED OVER IOWA AND MISSOURI WITH SOUTH FLOW INCREASING ACROSS THE FCST AREA. A SHORTWAVE TROF OVER CNTRL NEB WILL CONTINUE TO DRIFT. MEANWHILE A RIBBON OF HIGH RH WITH PRECIP WATER OF 2.00 OR MORE WILL ACCOMPANY IT. H7 DEWPOINTS ARE AROUND 9 DEG C AND ARE EXPECTED TO REMAIN AROUND 9 OR 10 DEG OVERNIGHT. AT THIS TIME...THE H85 PROFILERS ARE AROUND 15 TO 20KTS AND THERE ARE DIFFERENCES AS TO THE STRENGTH OF THE LOW LEVEL JET OVERNIGHT. THE NAM IS QUITE STRONG AT 40 TO 45KTS...WHILE THE SREF/RUC/GFS ARE NOT AS STRONG AT 35KTS. NEVER THE LESS...THIS STRENGTHENING LLJET COMBINE WITH THE SHORTWAVE TROUGH AND AID IN -SHRA/TSRA DEVELOPMENT. AT THIS TIME HAVE PLACED THE HIGHEST POPS IN THE NORTH THEN GRADUATED SOUTHWARD TO THE KS/NE LINE WITH SLIGHT CHC. THE STORM MOTION IS PRETTY GOOD AT 15 TO 20KTS...HOWEVER DUE TO THE HIGH PW WILL NEED TO BE AWARE THAT HEAVY RAIN WILL BE POSSIBLE WITH STORMS THAT FORM. THERE IS INSTABILITY AND SHEAR TO WORK WITH TONIGHT...SO CANNOT RULE OUT STRONG TO SEVERE STORMS. WITH THE HIGH MID LEVEL RH AND DRIER AIR BELOW...COULD SEE SOME GUSTY WINDS WITH THE HEAVY RAIN. LOWS TONIGHT MAY BE AFFECTED BY OUTFLOW FROM STORMS...AND HAVE UPR 60S IN THE NORTH FOR LOWS WITH LOWER 70S SOUTH. .LONG TERM...MONDAY THROUGH SUNDAY. THUNDERSTORM CHANCES WILL BE THE MAIN CONCERNS THE NEXT FEW DAYS. WE MAY NEED A HEAT ADVISORY FOR THE SOUTHERN PART OF THE FCST AREA ON MONDAY...BUT WILL LET OVERNIGHT SHIFT TAKE A LOOK AT THAT. POSSIBLE ONGOING CONVECTION AT 12Z MONDAY SHOULD TRY TO MOVE OUT OF THE AREA BY MID MORNING. MUCH OF THE DAY COULD BE DRY...WITH A CHANCE OF STORMS AGAIN TOWARD EVENING. TRIED TO DEPICT THAT WITH THREE HOUR BLOCKS IN THE WEATHER AND POP GRIDS FOR MONDAY. 12Z NAM OUTPUT SEEMED REASONABLE AND SUPPORTED PREVIOUS SCENARIO. BUT THE NAM MIGHT BE A BIT TOO WARM WITH TEMPERATURES ACROSS SERN NE AND SWRN IA MONDAY AFTERNOON. WENT WITH HIGHS IN THE LOWER 90S FOR OMAHA...MID 90S FOR LINCOLN AND UPPER 90S ALONG THE KS BORDER. IF THE 12Z NAM VERIFIES...WE WILL SEE HIGHS NEAR 105F AROUND FAIRBURY AND BEATRICE. DID NOT GO WITH THAT FOR NOW. MODELS DO INDICATE POCKETS OF SHEAR STRONG ENOUGH FOR SUPERCELLS ON MONDAY...BUT MAINLY RIGHT ALONG OR NORTH OF THE FRONTAL BOUNDARY THAT IS EXPECTED TO DROP SWD ACROSS THE AREA. 1 KM MIXED LAYER CAPE VALUES ARE IMPRESSIVE...WITH 2500-5000 J/KG FCST FOR MUCH OF THE AREA AT 21Z MONDAY. ANY STORM WILL HAVE POTENTIAL TO PRODUCE LOCALLY HEAVY RAIN...SINCE PRECIPITABLE WATER VALUES SHOULD BE 1.50 INCHES OR GREATER. STORMS THAT DO OCCUR WILL LIKELY FADE OUT BY LATE IN THE EVENING WITH FOCUS MORE TOWARD CNTRL AND ERN IA FOR THE OVERNIGHT HOURS. TUESDAY LOOKS LIKE A MAINLY DRY DAY BUT COULD NOT RULE OUT ISOLD LIGHT PCPN SO KEPT A SLIGHT CHANCE. TSTMS COULD FORM TUESDAY NIGHT NORTH OF FRONT...WHICH PUTS HIGHEST PCPN CHANCES ACROSS OUR SRN ZONES. LARGE SCALE 500 MB PATTERN FOR THE MID PART OF THE WEEK SHOWS A RIDGE ACROSS THE SRN U.S. WITH MODEST NEARLY ZONAL FLOW FOR THE NRN PART OF THE NATION. LATER IN THE WEEK IT APPEARS THAT THE FLOW WILL AMPLIFY A BIT AS A RIDGE POPS UP OVER THE WRN HIGH PLAINS AND A TROUGH DEVELOPS INTO THE NERN U.S. FROM CANADA. HEAT MAY BUILD A BIT OVER THE CNTRL PLAINS TOWARD NEXT WEEKEND IF RIDGE STRENGTHENS OVER THE SRN PLAINS LIKE THE MODELS SHOW. && .AVIATION... TAF SITES KOFK/KOMA/KLNK 18Z TAFS LOW LEVEL MOISTURE AND SOME HEATING HAS RESULTED IN A FEW CU. ALTHOUGH A MID LEVEL RIDGE IS OVER THE PLAINS...A WEATHER DISTURBANCE EMBEDDED IN THE FLOW WAS OVER COLORADO OVERNIGHT AND HAS PROGRESSED TO CNTRL NEB. AS A RESULT...THERE ARE SOME VFR CIGS OVR CNTRL NEB FM 10-15KFT AND A FEW ECHOES SHOWING UP ON RADAR. THIS FEATURE WILL CONTINUE TO DRIFT NORTHEAST AND AFFECT THE TAFS WITH INCREASING CLDS AND THE CHC FOR -SHRA/TSRA TONIGHT AND MONDAY MORNING. FARTHER NORTH...A SURFACE FRONT WILL BE THE FOCUS FOR PRECIPITATION. THIS FRONT WILL MOVE SOUTHWARD AND AFFECT THE TAF SITES AFTER 18Z. DUE TO THE COVERAGE HAVE OPTED TO INCLUDE A PROB30 STARTING AT 03Z AT KOFK AND AFT 05Z AT KLNK AND KOMA. WILL NEED TO MONITOR THOUGH SHOULD THE LLJET STRENGTHEN MORE THAN EXPECTED/EARLIER. LOCALIZED MVFR CIGS/VSBYS WILL BE POSSIBLE WITH ANY STORMS THAT FORM DUE THE HIGH PRECIP WATER/RH. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...NONE. IA...NONE. && SHORT TERM...ZAPOTOCNY LONG TERM....MILLER AVIATION...ZAPOTOCNY
