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, 1.1 hours before the alert went out and 186 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.

UPDATED FOR 00Z AVIATION DISCUSSION AND FOR SEVERE THUNDERSTORM WATCH.
&&
.DISCUSSION
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.

.PREV DISCUSSION... /ISSUED 345 PM CDT THU AUG 8 2013/
DISCUSSION...
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.
