What happened

The episode as NWS OAX wrote it up.

An upper level trough over the western U.S. pushed a cold front into central Nebraska during the overnight hours of June 11th and 12th. This system brought scattered heavy-rain producing thunderstorms to eastern Nebraska and western Iowa which produced some flooding. Additional heavy rain that fell on June 13th in western Iowa caused even more flooding or prolonged ongoing flooding.

326 AM CDT FRI JUN 11 2010

.DISCUSSION...
MAIN CONCERNS ARE CURRENT FLOODING AND THE FLOOD POTENTIAL THROUGH
TONIGHT. CURRENT MCS WILL CONTINUE TO AFFECT PARTS OF THE AREA.
THIS SHOULD DECREASE AS THE LOW LEVEL JET WEAKENS THIS MORNING.
QUESTION THEN BECOMES WHETHER OR NOT THERE WILL BE REDEVELOPMENT
TODAY OR IF IT WILL HOLD OFF UNTIL TONIGHT. 4 KM WRF-NMM DEVELOPS
STORMS FARTHER SOUTH LATE THIS AFTERNOON AND EVENING COMPARED TO
WHERE STORMS ARE NOW. THAT WOULD BE GOOD NEWS...EXCEPT STORMS WILL
PROBABLY EXPAND NORTH OVERNIGHT. WILL LET THE CURRENT FLASH FLOOD
WATCH STAY WHERE IT IS NOW AND THE DAY SHIFT WILL NEED TO EVALUATE.

HAVE HIGHEST POPS ACROSS THE SOUTHERN PARTS OF OUR AREA FOR THIS
EVENING...THEN CENTRAL AND NORTHERN AREAS OVERNIGHT. SOUTHERN AREAS
CAN TAKE MORE RAIN...BUT AREAS ALONG AND NORTH OF A LINE FROM ABOUT
DAVID CITY TO OMAHA CAN NOT. MIGHT NEED ANOTHER FLASH FLOOD WATCH
FOR TONIGHT PERIOD BUT WILL NOT ISSUE AT THIS TIME. ATMOSPHERE
WILL REMAIN VERY MOIST...WITH PRECIPITABLE WATER VALUES OF 1.50
TO 2.00 INCHES INTO SATURDAY. FRONTAL BOUNDARY WILL REMAIN IN
THE AREA THE NEXT FEW DAYS...SO KEPT POPS GOING.

MODELS SUGGEST LOWER CHANCES BY MONDAY NIGHT AND TUESDAY WITH
ACTIVITY SHIFTING TO THE SOUTH. THERE IS STILL QUITE A BIT OF
UNCERTAINTY FARTHER OUT...SO DID NOT MAKE MANY CHANGES BEYOND
ABOUT TUESDAY.

Flood, Fremont

When: June 11, 12:00 PM CST to June 16, 10:30 AM CST
Where: Fremont County, Hamburg to 0.52 mi W of Riverton
Cause: Heavy Rain
Property damage: $5,000
Reported by: Official NWS Observations
Coordinates: 40.600, -95.650

Heavy rain prior to and after June 11 caused flooding of the Nishnabotna River in southwest Iowa. The river near Hamburg crested at almost 27 feet around midnight CDT on June 15. Flood stage is 23 feet. The river near Hamburg was above flood stage from the early afternoon of June 11 until the late morning of June 16th. Levees near town protected significant damage, but some agricultural lowlands near the river were flooded as were some other places near town.

What these are

Flood: Flooding that develops more slowly than a flash flood: rivers leaving their banks, or water standing over land for an extended time.

After NWS Directive 10-1605, the rules offices file Storm Data by.
