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
Little Rock, AR (KLZK), launched 00:00Z, 4.3 hours before the alert went out and 43 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.

.PREV DISCUSSION... /ISSUED 240 PM CST FRI FEB 27 2009/
DISCUSSION...
QUITE AN ACTIVE WEATHER PATTERN FOR NEXT 24 HOURS OR SO. COLD
FRONT HUNG UP ACROSS NORTH MISSISSIPPI THIS AFTERNOON. A LARGE
AREA OF SHOWERS AND THUNDERSTORMS CAN BE FOUND JUST SOUTH OF THE
FRONT. SEVERE THREAT FOR THE NEXT COUPLE OF HOURS SHOULD REMAIN
SOUTH OF THE FORECAST AREA SO THE SEVERE THUNDERSTORM WATCH WILL
EXPIRE AT 3 PM CST. SOME ADDITIONAL STRONG TO SEVERE STORMS MAY MOVE
INTO SOUTHERN PORTIONS OF THE FORECAST AREA LATER TONIGHT SO WILL
KEEP MENTION OF POSSIBLE SEVERE STORMS IN THE HWO. IN ADDITION...
THE LARGE AREA OF RAIN THAT HAS ALREADY OCCURRED PLUS THE THREAT
OF MORE RAIN IN THE SAME AREA HAS PROMPTED A FLASH FLOOD WATCH TO
BE ISSUED FOR TONIGHT. MORE RAIN SHOULD MOVE ACROSS MUCH OF THE
FORECAST AREA TONIGHT.
AS IF THAT WERENT ENOUGH...AN UPPER LEVEL LOW CURRENTLY OVER
WESTERN SOUTH DAKOTA WILL PLUNGE SOUTHEAST TONIGHT AND SATURDAY
REACHING THE MIDSOUTH BY SATURDAY NIGHT. THE RESULT WILL BE A
CONTINUANCE OF WIDESPREAD RAIN OVER THE REGION. AS THE LOW GETS
CLOSER TO THE FORECAST AREA TEMPERATURES WILL COOL PARTICULARLY
NEAR THE TRACK OF THE LOW. THE RESULT WILL BE A CHANGE FROM RAIN
TO SNOW STARTING IN THE NORTHWEST PART OF THE FORECAST AREA AROUND
NOON. BY SATURDAY EVENING...RAIN SHOULD HAVE CHANGED OVER TO SNOW
ACROSS MOST OF THE FORECAST AREA. AT THIS POINT...IT APPEARS THAT
MOST AREAS COULD SEE 1-2 INCHES OF SNOW MAINLY ON GRASSY SURFACES.
HOWEVER...THE AMOUNT OF SNOW WILL BE HIGHLY DEPENDENT ON THE TRACK
OF THE UPPER LOW SO THIS REMAINS QUITE A BIT OF UNCERTAINTY. WILL
ISSUE A SPECIAL WEATHER STATEMENT HIGHLIGHTING THE THREAT FOR
SNOW.
BY SUNDAY MORNING...THE UPPER LOW WILL BE EAST OF THE FORECAST
AREA AND HIGH PRESSURE WILL DOMINATE THE CENTRAL U.S. RESULTING IN
DRY WEATHER AND CHILLY TEMPERATURES FOR SUNDAY AND SUNDAY NIGHT.
UPPER LEVEL RIDGE WILL GRADUALLY BUILD INTO THE REGION BEGINNING
MONDAY AND CONTINUING THROUGH NEXT FRIDAY. THE RESULT WILL BE A
GRADUAL WARMING TREND WITH LITTLE CHANCE FOR RAIN.
