The episode as NWS OAX wrote it up.
A warm front lifted northeast across northeast Nebraska during the day on June 10th while a cold front moved into central Nebraska. Heavy rain producing thunderstorms, a few severe, crossed the area on the 10th and additional thunderstorms that formed on the cold front raced across the area early on the 11th. The storms that moved across northeast Nebraska early on the 11th produced areas of damaging winds in northeast Nebraska and additional heavy rain. The heavy rain from the storms aggravated the flooding situation that began on the 10th and additional rains after the 11th only prolonged the flooding situation. The resultant flooding caused at least 20 million dollars in damage to public property in Nebraska in mid to late June which didn't even factor in private property or crop losses. The White house declared a federal disaster in 53 Nebraska counties for June flooding.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
416 PM CDT THU JUN 10 2010
.DISCUSSION...
MAIN CONCERN IS FLOODING TONIGHT FROM POSSIBLE MCS.
NW TO SE SFC WARM FRONTAL BOUNDARY EXTENDS ACROSS THE CWA. VIGOROUS
UPR LEVEL SHORTWAVE TROF BROUGHT ROUND OF THUNDERSTORMS ACROSS THE
AREA THIS MORNING. ORNING RAOBS INDICATE ABUNDANT MOISTURE ACROSS
THE CENTRAL PLAINS. PRECIPITABLE WATER IS NEARLY 2 INCHES OVER THE
AREA. THIS MORNINGS THUNDERSTORMS HAVE DUMPED 3 TO 4 INCHES OF RAIN
IN SOME AREAS. FLASH FLOODING HAS TAKEN PLACE AND IT WOULD NOT TAKE
MUCH MORE WATER TO CREATE A FLOODING SITUATION TONIGHT. THE QUESTION
IS HOW FAR SOUTH WILL TONIGHT/S MCS AFFECT. AT THIS TIME WE WILL
ISSUE A FLASH FLOOD WATCH TONIGHT FROM JUST SOUTH OF THE PLATTE
RIVER NORTHWARD.
BOUNDARY REMAINS IN THE AREA ON FRIDAY...ALTHOUGH MUCH OF THE DAY ON
FRIDAY MAY BE CAPPED. ANOTHER NOCTURNAL MCS MAY AFFECT THE AREA
FRIDAY NIGHT. ON SATURDAY...A COLD FRONT WILL MOVE SOUTHEAST ACROSS
THE AREA WITH ANOTHER WAVE OF THUNDERSTORMS.
MAIN FORECAST CONCERN IN THE LONG TERM REMAINS THE CONTINUED PRECIP
CHANCES THROUGH THE FORECAST PERIOD. CURRENT MODEL SOLUTIONS ARE IN
FAIRLY GOOD AGREEMENT EARLY...AS A TROUGH OVER THE WRN CONUS
CONTINUES TO DEEPEN AND MOVE NORTHEAST OVER THE ROCKIES. THE BROAD
RIDGE EXTENDING FROM THE ROCKIES TO THE EAST COAST WILL BEGIN TO
SHIFT EAST SUNDAY AS THE TROUGH DEEPENS IN THE WEST. A SHORTWAVE IS
FORECAST TO MOVE NORTHEAST OUT OF SOUTHERN COLORADO SUNDAY LIFTING A
BOUNDARY NORTH OUT OF KANSAS. SUFFICIENT SFC TO MID LVL FLOW WILL
CONTINUE TO SUPPLY MOIST UNSTABLE AIR AHEAD OF THIS SYSTEM...
SUPPORTING PRECIP DEVELOPMENT. INTRODUCE SLIGHT CHANCE POPS ACROSS
SOUTHEAST NEBRASKA AND SOUTHWEST IOWA BEGINNING 12Z SUNDAY. CONTINUE
TO CARRY SLIGHT TO CHANCE POPS THROUGH TUESDAY MORNING AS THE TROUGH
CONTINUES TO MOVE NORTHEAST OVER THE DAKOTAS. WEAK HIGH PRESSURE IS
EXPECTED TO BUILD IN ACROSS THE FA ON TUESDAY LOWERING THE CHANCE
FOR PRECIP. HAVE INTRODUCED A DRY FORECAST TUESDAY THRU WEDNESDAY
NIGHT AS DRY WESTERLY FLOW MOVES INTO THE AREA. WEDNESDAY INTO
THURSDAY MORNING...A TROUGH MOVES OVER THE PAC NW STEEPENING THE
RIDGE OVER THE PLAINS. MODELS REVEAL A SHORTWAVE TRAVERSING
NORTHEAST ALONG THE UPPER LEVEL FLOW. SOUTHERLY RETURN FLOW WILL
AGAIN TRANSPORT MOISTURE INTO THE REGION AHEAD OF AN ADVANCING
FRONTAL BOUNDARY ACROSS THE PLAINS. HAVE PLACED SLIGHT TO CHANCE
POPS ACROSS THE REGION TO ACCOUNT FOR THIS SYSTEM. TEMPERATURES
THROUGH THE LONG TERM WILL MAINLY RESIDE IN THE MID TO UPPER 70S AS
CONTINUING CHANCES OF RAIN AND CLOUD COVER WILL KEEP TEMPS DOWN.
TEMPS ARE EXPECTED TO RAISE INTO THE 80S BY WEDNESDAY AS THE WEAK
HIGH PRESSURE SETS UP ACROSS THE AREA.
&&
.AVIATION...
VFR CIGS ARE EXPECTED AT KOFK AND KLNK EARLY IN THE PERIOD AS CLOUDS
CONTINUE TO CLEAR BEHIND THIS MORNINGS SYSTEM. KOMA CONTINUES TO
SWITCH BETWEEN MVFR AND VFR CIGS AS LINGERING LOW LEVEL STRATUS
CONTINUES TO MOVE OUT OF THE AREA. SOUTH WINDS HAVE RETURNED TO THE
REGION ADVECTING MOIST UNSTABLE AIR BACK INTO THE AREA AHEAD OF
ANOTHER APPROACHING UPPER LEVEL DISTURBANCE EXPECTED TO MOVE INTO
THE REGION LATE TONIGHT. SURFACE LOW PRESSURE OVER WESTERN KANSAS IS
FORECAST TO LIFT NORTH INTO CENTRAL NEBRASKA...SETTING UP A FRONTAL
BOUNDARY ACROSS THE REGION LATE TONIGHT. THIS BOUNDARY WILL BE THE
FOCAL POINT FOR POSSIBLE STORM DEVELOPMENT LATE TONIGHT INTO FRIDAY
MORNING. CURRENTLY HAVE PROB30 GROUP FOR IFR CIGS AND -TSRA AT KOFK
AND TSRA AT KOMA BEGINNING AT 06Z. HAVE PROB30 GROUP FOR MVFR CIGS
AND -SHRA AT KLNK BEGINNING AT 06Z.
