The radar
The Columbus AFB radar (KGWX), 95 km from the middle of the area, began a volume at 03:52 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
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 00:00Z, 3.9 hours before the alert went out and 102 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...UPDATED
NATIONAL WEATHER SERVICE MEMPHIS TN
859 PM CDT THU AUG 8 2013
.UPDATE...
WENT AHEAD AND ISSUED A FLASH FLOOD WATCH UNTIL 5 AM FOR PORTIONS
OF EAST CENTRAL AND NORTHEAST AR...THE MO BOOTHEEL...INTO MUCH OF
WEST TN. THE FLASH FLOOD WATCH INCLUDES JONESBORO AND
JACKSON...AND IS MAINLY ALONG AND NORTH OF INTERSTATE 40. DID
LEAVE SHELBY COUNTY (CITY OF MEMPHIS) OUT OF THE FLASH FLOOD
WATCH...BUT WILL MONITOR IN CASE ANY OUTFLOW BOUNDARIES BECOME
STATIONARY THROUGH THIS AREA. OTHERWISE...UPPER LEVEL DISTURBANCES
WILL RIDE WEST TO EAST ALONG A NEARLY STATIONARY FRONT FROM
NORTHEAST AR INTO NORTHWEST TN. NUMEROUS SHOWERS AND THUNDERSTORMS
ARE EXPECTED ALONG AND NORTH OF THE STATIONARY FRONT. MOISTURE
VALUES ARE VERY HIGH WITH SURFACE DEW POINTS IN THE UPPER 70S IN
MANY SPOTS. BETWEEN 2 AND 4 INCHES OF RAIN...LOCALLY MORE...IS
EXPECTED TO OCCUR IN MANY SPOTS WITHIN THE FLASH FLOOD WATCH.
FLASH FLOOD GUIDANCE VALUES ARE ON THE LOW SIDE WITH ALL THE
RECENT RAIN.

.PREV DISCUSSION... /ISSUED 814 PM CDT THU AUG 8 2013/
AN ACTIVE WEATHER NIGHT IS DEVELOPING ACROSS THE MIDSOUTH.
THUNDERSTORMS HAVE DEVELOPED ALONG A NEARLY STATIONARY FRONT FROM
NORTHEAST AR INTO NORTHWEST TN. SURFACE BASED CAPES THROUGH THIS
AREA ARE VERY UNSTABLE NEAR 5000 J/KG. RADAR HAS INDICATED A FEW
OF THESE STORMS BEING STRONG WITH GUSTY WINDS ABOUT 30 TO 40
MPH...AND RAINFALL RATES NEAR 2 INCHES PER HOUR. RADAR INDICATES
OUTFLOW BOUNDARIES PUSHING SOUTH-SOUTHEASTWARD FROM THESE STORMS
WHICH MAY INITIATE ADDITIONAL THUNDERSTORMS INCLUDING ACROSS THE
MEMPHIS AREA. IN ADDITION...CLUSTER OF THUNDERSTORMS HAVE
DEVELOPED AND ARE INCREASING FROM NORTHWEST AR INTO NORTH CENTRAL
AR. THESE STORMS ARE GENERALLY PUSHING EASTWARD TOWARD NORTHEAST
AR AND THE MO BOOTHEEL...AND WILL AFFECT NORTHWEST TN LATER
TONIGHT. A FEW OF THESE STORMS MAY BE SEVERE AS THEY MOVE INTO
PORTIONS OF EAST CENTRAL AND NORTHEAST AR...AND THE MO BOOTHEEL.
OUTFLOW BOUNDARIES FROM THE STORMS TONIGHT COULD AFFECT AREAS AS
FAR SOUTH AS THE EXTREME NORTHERN PARTS OF NORTH MS. UPDATED TO
READJUST THE POPS FOR THE REMAINDER OF TONIGHT BASED ON THIS
THINKING. ALSO HAVE ALREADY INCLUDED THE MENTION OF SEVERE
THUNDERSTORMS WHERE THE SEVERE THUNDERSTORM WATCH WAS ISSUED FOR
PORTIONS OF NORTHEAST AND EAST CENTRAL AR ALONG WITH THE MO
BOOTHEEL. THE 00Z LITTLE ROCK SOUNDING SHOWS A PRECIPTABLE WATER
VALUE OF 1.85 INCHES...BUT VALUES ARE PROBABLY A LITTLE HIGHER
FROM NORTHEAST AR AND THE MO BOOTHEEL INTO NORTHWEST TN. THE 00Z
NASHVILLE SOUNDING INDICATED A PW OF 2.09 INCHES WHICH IS PROBABLY
CLOSER. AM DEBATING WHETHER TO ISSUE A FLASH FLOOD WATCH TONIGHT
FROM PORTIONS OF NORTHEAST AR AND THE MO BOOTHEEL INTO NORTHWEST
TN. STAY TUNED.
JCL
PREV DISCUSSION... /ISSUED 634 PM CDT THU AUG 8 2013/
UPDATED THE ZONE FORECASTS AND GRIDS FOR SEVERE THUNDERSTORM
WATCH ISSUED FOR PORTIONS OF EAST AR AND THE MO BOOTHEEL UNTIL
MIDNIGHT. RAISED POPS BEFORE MIDNIGHT IN SOME LOCATIONS OF THE
WATCH AS THE HIGH RESOLUTION RAPID REFRESH MODEL SHOWS A CLUSTER
OF SHOWERS AND THUNDERSTORMS MOVING INTO THIS AREA BEFORE
MIDNIGHT. DAMAGING WINDS...LARGE HAIL...AND LOCALLY HEAVY RAINFALL
WITH LOCALIZED FLASH FLOODING AREA POSSIBLE. SATELLITE AND RADAR
ALREADY SHOWING A CLUSTER OF THUNDERSTORMS INCREASING ACROSS NORTH
CENTRAL AR AND MOVING EAST. ADDITIONAL THUNDERSTORMS ARE
DEVELOPING FROM NORTHEAST AR INTO NORTHWEST TN ALONG A STATIONARY
FRONT...MAY NEED TO UPDATE AGAIN TO RAISE POPS ACROSS PORTIONS OF
NORTHWEST TN. HAZARDOUS WEATHER OUTLOOK HAS ALSO BEEN UPDATED.
JCL
PREV DISCUSSION... /ISSUED 345 PM CDT THU AUG 8 2013/
CURRENTLY...A STATIONARY FRONT EXTENDS ROUGHLY FROM SOUTHERN
MISSOURI/NORTHERN ARKANSAS INTO THE OHIO VALLEY. THE MCV GENERATED
BY THIS MORNINGS MCS IS HEADING NE ACROSS SOUTHERN ILLINOIS. THE
UPPER RIDGE OVER TEXAS AND THE LOWER MS VALLEY HAS NUDGED A LITTLE
TO THE NORTHEAST TODAY INTO THE MID-SOUTH WHICH IS HELPING TO KEEP
MOST OF THE CONVECTIVE ACTIVITY TO THE NORTH AND EAST OF THE
FORECAST AREA. A FEW SHOWERS AND THUNDERSTORMS ARE FORMING ALONG
THE TN RIVER AND ACROSS NE MS DUE TO A COMBINATION OF DAYTIME
HEATING AND LEFTOVER BOUNDARIES. TEMPERATURES HAVE ALSO CLIMBED
INTO THE LOWER AND MID 90S ACROSS MUCH OF THE SOUTHERN PART OF THE
AREA. THESE HOT TEMPERATURES COMBINED WITH WITH DEWPOINTS IN THE
MID 70S ARE RESULTING IN HEAT INDEX VALUES AROUND 105 DEGREES. A
HEAT ADVISORY IS IN EFFECT FOR EAST CENTRAL ARKANSAS...EXTREME
SOUTHWEST TN AND MUCH OF NORTH MISSISSIPPI.
TONIGHT AND FRIDAY...THE SHOWERS AND THUNDERSTORMS OVER NE MS WILL
DISSIPATE FAIRLY QUICKLY THIS EVENING AND AREAL COVERAGE THIS
EVENING WILL BE FAIRLY LOW...ESPECIALLY SOUTH OF I-40. EXPECT
ANOTHER MCS TO DEVELOP ALONG THE STATIONARY FRONT NEAR THE AR/MO
BORDER TONIGHT AND SLIDE EAST...SKIRTING THE NORTHERN TIER OF THE
MIDSOUTH. WENT WITH THE HIGHEST POPS ALONG THE MO/KY BORDERS AND
TAPERED THEM OFF TOWARD THE SOUTH. COULD BE A FEW STRONG STRONG
WITH LOCALLY HEAVY RAIN ACROSS THE NORTHERN TIER LATER TONIGHT.
ANOTHER MILD NIGHT EXPECTED WITH LOWS IN THE MID 70S. A MCS WILL
PROBABLY BE FALLING APART ALONG THE KY/TN BORDER IN THE MORNING.
THE MODELS TRY TO NUDGE THE FRONT A LITTLE SOUTH SO WENT WITH
LIKELY POPS ALONG THE NORTHERN TIER COUNTIES FOR FRIDAY. PRECIP
CHANCES WILL TAIL OFF TOWARD THE SOUTHWEST WHERE THE UPPER RIDGE
IS TRYING TO HOLD ON. EXPECT ANOTHER HOT AND HUMID DAY ACROSS
SOUTHERN SECTIONS AND A HEAT ADVISORY REMAIN IN EFFECT THROUGH
FRIDAY EVENING.
FRIDAY NIGHT THROUGH SUNDAY...THE UPPER RIDGE WEAKENS A BIT AND
THE FRONT NUDGES SOUTH INTO NORTHERN PARTS OF THE MIDSOUTH. AS A
RESULT CHANCES FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH
THE WEEKEND. THE FRONT ALONG WITH THE WEAKENED RIDGE SHOULD HELP
BREAK THE HIGH HEAT ACROSS THE SOUTH THOUGH HEAT INDEX VALUES
AROUND 100 DEGREES WILL BE COMMON ACROSS NORTH MISSISSIPPI WITH
HIGHS IN THE LOWER 90S. TEMPS WILL BE COOLER UP NORTH WITH HIGHS
IN THE MID 80S BOTH DAYS.
MONDAY AND TUESDAY...MODELS IN OK AGREEMENT AS AN UPPER TROUGH
BEGINS TO DEEPEN OVER THE EASTERN U.S. AND THE FLOW ALOFT BECOMES
A LITTLE MORE NORTHWESTERLY OVER THE MIDSOUTH EARLY IN THE WEEK
WITH A STALLED FRONT SOMEWHERE IN THE REGION. COULD BE AN MCS
PATTERN. CHANCES FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE AND
TEMPERATURES WILL BE SLIGHTLY BELOW NORMAL.
WEDNESDAY AND THURSDAY...UPPER TROUGH CONTINUES TO DEEPEN OVER THE
EASTERN U.S. DURING THIS PERIOD WHICH SHOULD DRIVE THE BOUNDARY
SOUTH OF THE AREA AT SOME POINT. WILL CONTINUE WITH SLIGHT CHANCE
POPS AND BELOW NORMAL TEMPERATURES.

.AVIATION...
00Z TAF CYCLE
SCATTERED CONVECTION CURRENTLY NEAR JBR WILL CONTINUE TO BECOME
MORE ACTIVE AS STORMS IN WESTERN ARKANSAS CONGEAL AND TRACK
EASTWARD TONIGHT. FOR NOW HAVE PLACED THUNDER ON STATION AT
JBR...WITH SHOWERS AT MEM AND MKL...WHERE CONFIDENCE IS NOT AS
HIGH. FURTHER SOUTH...CONVECTION NEAR TUP IS EXPECTED TO WEAKEN
OVER THE NEXT COUPLE OF HOURS.
CIGS WILL REMAIN VFR THROUGH THE PERIOD...WITH MVFR VISIBILITIES
IN SHOWERS/STORMS...ALONG WITH STRONGER WINDS. OTHERWISE...WINDS
WILL BE LIGHT AND VARIABLE AT TUP...JBR...AND MKL
OVERNIGHT...TURNING SOUTH ON FRIDAY. MEM WILL SEE SOUTHEAST TO
SOUTH WINDS AT 6-8 KTS THROUGH THE PERIOD. A WEAK COLD FRONT WILL
FINALLY PUSH THROUGH JBR LATE IN THE PERIOD SHIFTING WINDS TO THE
NORTHEAST.
