Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Omaha, NE (KOAX), launched 00:00Z, 1.4 hours before the alert went out and 136 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Aug 16, 2:32 PM CDT, 5 hours 51 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
232 PM CDT WED AUG 16 2006

.SHORT TERM...SHOWERS AND ISOLATED THUNDERSTORMS FINALLY GETTING
GOING WITH SHORT WAVE...INCREASED ISENTROPIC LIFT...AND H25
JET MOVING INTO MORE FAVORABLE POSITION THROUGH THE EVENING.
HAVE CONTINUED WITH HIGH CHANCE/COVERAGE POPS...AS MANY PLACES
WILL SEE RAIN BUT SIZE AND COVERAGE MAKES IT ALMOST ISOLATED
IN NATURE. ONE ISSUE IS A FEW FOLKS LIKE TO GET SOME PRETTY
HEAVY AND HARD RAIN...WITH ATMOSPHERE PRETTY JUST WITH 1.5
INCHES OF PRECIPITABLE WATER. SEVERE WEATHER LOOKS VERY
UNLIKELY...WITH MID LEVEL LAPSE RATES VERY SHALLOW...ONLY
ABOUT 5 C/KM AND SHEAR WEAK.

APPEARS SOUTHERN ZONES WILL BE IN LESS FAVORABLE REGIME FOR
PRECIPITATION POST SUNSET...AND HAVE FOCUS BETTER CHANCES
FURTHER NORTH THEREAFTER.

GOTTA MAKE A CALL AT SOME POINT...AND WHILE THERE IS A RISK
FOR ANYTHING IN THE 12 TO 60 PERIOD...IT JUST ISN/T GOING
TO RAIN ALL THE TIME. SOUTHEAST ZONES HAVE PROBABLY BEST
SHOT THURSDAY...BUT EVEN THAT LOOKS SLIM...AS BOTH UPPER
SUPPORT AND LOW LEVEL FOCUS APPEAR WEAK. FRIDAY PROBABLY
A BETTER SHOT...AT LEAST LATER IN THE DAY...WITH APPROACHING
FRONT AND INCREASED UPPER LEVEL SUPPORT.

.LONG TERM...12Z SATURDAY THROUGH WEDNESDAY. MAIN FORECAST
CHALLENGES REVOLVE AROUND CHANCES OF PRECIPITATION EARLY IN THE
PERIOD...THEN INCREASING TEMPERATURES THROUGHOUT THE REMAINDER OF
THE PERIOD. ON SATURDAY...SLIGHT CHANCES OF PRECIPITATION WILL
BECOME CONFINED TO CENTRAL AND SOUTHERN PORTIONS OF THE FORECAST
AREA AS THE SURFACE FRONT PUSHES SOUTHWARD INTO CENTRAL KANSAS.
THESE CHANCES WILL TAPER OFF TO ZERO BY LATE SATURDAY NIGHT. ON
SUNDAY...AN UPPER RIDGE OVER THE SOUTH CENTRAL U.S. WILL BUILD WEST
AND THIS WILL INDUCE A DOWNSLOPING WESTERLY FLOW ALOFT OVER THE
FORECAST AREA. SURFACE HIGH PRESSURE CENTERED OVER SOUTH CENTRAL
NEBRASKA ALONG WITH A STABLE EASTERLY LOW LEVEL FLOW WILL BRING A
DRY DAY ON SUNDAY WITH TEMPERATURES RISING TO LEVELS SLIGHTLY ABOVE
THOSE RECORDED ON SATURDAY.

MONDAY AND TUESDAY...UPPER LEVEL HIGH PRESSURE WILL SLOWLY
STRENGTHEN OVER THE WESTERN U.S. WITH A DRY NORTHWESTERLY FLOW
ENSUING ALOFT FOR THE FORECAST AREA. SLOWLY RISING
HEIGHTS/THICKNESSES WILL BRING A DEGREE OR TWO OF WARMING EACH DAY
WITH DAYTIME HIGH TEMPERATURES GENERALLY RISING IN THE UPPER 80S
OVER SOUTH CENTRAL NEBRASKA AND LOWER 90S OVER THE NORTH CENTRAL
KANSAS COUNTIES. ON WEDNESDAY...STRONG RIDGING OVER THE WESTERN U.S.
WILL BRING A DRY NORTH-NORTHWESTLY FLOW ALOFT. A SOUTHWESTERLY
SURFACE FLOW WILL BRING SOME WARM AIR ADVECTION TO THE REGION FOR
SLIGHTLY HIGHER DAYTIME HIGH TEMPERATURES THAN ON MONDAY AND
TUESDAY.
