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 severe thunderstorm 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, 1.5 hours before the alert went out and 48 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 646 PM CDT FRI AUG 31 2012 .UPDATE... UPDATED FOR AVIATION. && .PREV DISCUSSION... /ISSUED 353 PM CDT FRI AUG 31 2012/ DISCUSSION...20Z SURFACE ANALYSIS PLACES THE REMNANTS OF TROPICAL DEPRESSION ISAAC ACROSS SOUTHWEST MISSOURI WITH SHOWER AND THUNDERSTORM ACTIVITY CONFINED PREDOMINANTLY TO THE MISSISSIPPI RIVER DELTA AND NORTHEAST MISSISSIPPI. TEMPERATURES AS OF 3 PM CDT RANGE FROM THE 80S ACROSS EASTERN ARKANSAS WHERE CLOUD COVER HAS PERSISTED THROUGHOUT THE DAY AND UPPER 80S TO LOWER 80S ACROSS THE REMAINDER OF THE MID SOUTH WHERE CLOUD COVER HAS MIXED OUT TODAY. WIND ADVISORY CONCERNS ALONG WITH THE POTENTIAL FOR STRONG TO PERHAPS SEVERE THUNDERSTORMS INTO THIS EVENING ARE THE MAIN CONCERNS IN THIS AFTERNOON/S FORECAST ISSUANCE. SHORT TERM...(TONIGHT THROUGH MONDAY)...THE REMNANTS OF TROPICAL DEPRESSION ISAAC ACROSS SOUTHWEST MISSOURI ALONG WITH DAYTIME INSTABILITY PRODUCED BY SOME SUNSHINE TODAY HAVE PRODUCED FAVORABLE CONDITIONS FOR MINI-SUPERCELL TYPE STORMS TO DEVELOP MAINLY ACROSS EAST ARKANSAS AND THE MISSOURI BOOTHEEL. MODERATELY STEEP LOW LEVEL LAPSE RATES AROUND 6.5 C/KM...0-1 STORM RELATIVE HELICITY VALUES BETWEEN 200-250 M2/S2...SURFACE BASED CAPE VALUES BETWEEN 500-1000 J/KG...SUPPORT THE CONTINUED DEVELOPMENT OF LOW TOPPED MINI-SUPERCELLULAR TYPE STORMS CAPABLE OF PRODUCING BRIEF SHORT-LIVED TORNADOES. THINK THIS THREAT WILL BEGIN TO DIMINISH AFTER SUNSET AS THE BEST SHEAR LIFTS NORTH OF THE MID SOUTH. LATEST WATER VAPOR SATELLITE/WSR-88D VAD WIND PROFILERS INDICATE 925 MB WINDS BETWEEN 25-35 KTS ACROSS THE MISSISSIPPI RIVER DELTA. THUS...DECIDED TO EXTEND THE CURRENT WIND ADVISORY UNTIL 6 PM THIS EVENING. SHORT TERM MODELS INDICATE THE REMNANTS OF ISAAC WILL CONTINUE TO MOVE EAST ACROSS CENTRAL MISSOURI ALONG THE I-70 CORRIDOR THROUGH SUNDAY AND INTO THE OHIO VALLEY BY MONDAY. THIS WILL RESULT IN THE CONTINUED POTENTIAL FOR SHOWERS AND THUNDERSTORMS EACH DAY...ESPECIALLY DURING THE DAY WITH MAXIMUM HEATING AND INSTABILITY. A FEW STRONG THUNDERSTORMS WILL REMAIN POSSIBLE DURING THIS PERIOD WITH GUSTY WINDS POSSIBLE. LONG TERM...(TUESDAY THROUGH FRIDAY)...12Z LONG TERM MODELS INDICATE A COLD FRONT WILL MOVE THROUGH THE MID SOUTH NEXT WEDNESDAY NIGHT AND THURSDAY AS AN UPPER LEVEL TROUGH MOVES INTO THE EASTERN UNITED STATES. THUS...KEPT SLIGHT CHANCE/POPS IN THE FORECAST UNTIL THE FRONT PASSES THROUGH. HIGH PRESSURE WILL RETURN FOR THE REMAINDER OF THE LONG TERM FORECAST. CJC && .AVIATION... 00Z TAFS PRIMARY FORECAST CONCERN IS CONVECTIVE LINE LIFTING NORTHEAST THROUGH EASTERN AR. THIS LINE REPRESENTS THE FIRST REAL CHANCE OF TS AT MEM FOR THE DAY. THIS LINE IS RATHER STRONGLY FORCED... BUT WILL BE ENCOUNTERING A GRADUALLY STABILIZING LOWER ATMOSPHERE BY THE TIME IT APPROACHES THE MS RIVER. HRRR MODEL SHOWS THIS LINE WEAKENING OVER TIME AND HAVE PLACED A PREDOMINATE SHRA WITH VCTS IN FOR MEM. TIME OF ARRIVAL TOOL PLACES THIS LINE NEAR MEM AT 0215Z.
