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 (KBYH), launched 12:00Z, 11.9 hours before the alert went out and 160 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 6, 3:50 PM CDT, 3 hours 5 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MEMPHIS TN 350 PM CDT WED AUG 6 2014 .DISCUSSION... A WEAK SURFACE FRONT REMAINS STRETCHED ACROSS NORTHEAST PORTIONS OF THE FORECAST AREA THIS AFTERNOON. WEAK NORTHWEST FLOW ALOFT ALONG WITH LIFT ALONG THE FRONT AND STRONG INSTABILITY...WITH MLCAPES IN EXCESS OF 2500 J/KG...WILL RESULT IN A CORRIDOR OF SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THIS AFTERNOON AND EARLY EVENING. THIS AREA WILL EXTEND FROM THE MISSOURI BOOTHEEL INTO NORTHWEST TENNESSEE. LATER THIS EVENING...CONVECTION SHOULD DIMINISH IN COVERAGE. BY LATE TONIGHT...A MID LEVEL SHORTWAVE NOW OVER THE SOUTHERN PLAINS WILL BEGIN TO ENHANCE LIFT OVER NORTHWEST SECTIONS OF THE REGION AND RESULT IN INCREASING CHANCES FOR ADDITIONAL SHOWERS AND THUNDERSTORMS BEFORE SUNRISE. THE SHORTWAVE DISTURBANCE WILL CONTINUE TO SLOWLY MOVE ACROSS THE REGION THURSDAY AND THURSDAY NIGHT BRINGING SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS. THE GREATEST POTENTIAL FOR STORMS WILL REMAIN ACROSS THE NORTH HALF OF THE REGION IN CLOSEST PROXIMITY TO A STALLED SURFACE BOUNDARY AND ANY LEFT OVER OUTFLOW BOUNDARIES. MODERATE TO STRONG INSTABILITY MAY ALLOW A FEW STORMS TO BECOME STRONG TO SEVERE MAINLY THURSDAY AFTERNOON AND EVENING. LOCALIZED HEAVY RAINFALL WILL ALSO BE POSSIBLE AS PRECIPITABLE WATER VALUES EXCEED 2 INCHES. SEVERAL DISTURBANCES WILL MOVE ACROSS THE MID SOUTH IN NORTHWEST FLOW ALOFT THROUGH THE WEEKEND AS A SURFACE FRONTAL BOUNDARY REMAINS QUASI-STATIONARY ACROSS THE REGION. THIS SHOULD RESULT IN PERIODS OF UNSETTLED WEATHER AND HIGHER THAN CLIMO POPS THROUGH SUNDAY...ESPECIALLY ACROSS THE NORTHERN HALF OF THE AREA. A FEW STRONG TO SEVERE THUNDERSTORMS ALONG WITH HEAVY RAINFALL CANNOT BE RULED OUT THROUGH THE PERIOD AS MODERATE INSTABILITY REMAINS IN PLACE AND DEEP LAYER SHEAR BECOMES ENHANCED WITH EACH PASSING SHORTWAVE. TEMPERATURES WILL AVERAGE NEAR TO SLIGHTLY BELOW NORMAL THROUGH THE PERIOD ALONG WITH SEASONABLY HIGH HUMIDITY LEVELS. BROAD UPPER LEVEL TROUGHING SHOULD REMAIN IN PLACE EVEN INTO NEXT WEEK WHICH SHOULD KEEP CHANCES FOR SHOWERS AND THUNDERSTORMS ONGOING ACROSS PORTIONS OF THE MID SOUTH. TEMPERATURES SHOULD REMAIN SEASONABLE THROUGH THE EXTENDED FORECAST PERIOD. JLH && .AVIATION... 18Z TAF SET VFR CONDITIONS EXPECTED THROUGH THE PERIOD. HAVE REMOVED MENTION OF VCTS WORDING AT KJBR AS CONVECTION THIS AFTERNOON SHOULD STAY WELL TO THE NORTH. HAVE ALSO REMOVED MENTION OF FOG AT KMKL AND KTUP AS NO FOG OCCURRED THIS MORNING THUS SEE NO REASON WHY IT WOULD OCCUR TONIGHT. HOWEVER...DID MENTION VCTS WORDING AT KJBR AFTER 13Z AS A DYING MCS MAY MOVE INTO NE ARKANSAS DURING THE MORNING HOURS. W WINDS AROUND 6-8 KTS WILL BECOME LIGHT AND VARIABLE AFTER 00Z. EXPECT WINDS TO BECOME SW AT 5-7 KTS AROUND 14-15Z. KRM && .MEG WATCHES/WARNINGS/ADVISORIES... AR...NONE. MO...NONE. MS...NONE. TN...NONE. &&
