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
Nashville Metro, TN (KBNA), launched 12:00Z, 9.9 hours before the alert went out and 168 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
NATIONAL WEATHER SERVICE MEMPHIS TN
313 PM CDT SAT JUN 27 2009
.DISCUSSION...
A FEW ISOLATED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS
WEST TENNESSEE THIS AFTERNOON. ONE OR TWO OF THESE STORMS COULD
BECOME STRONG BUT SHOULD DIE OFF QUICKLY AFTER SUNSET WITH THE
LOSS OF DAYTIME HEATING. HEAT INDEX READINGS ACROSS THE MIDSOUTH
ARE CONSISTENTLY ABOVE 100 DEGREES AND SUSPECT ONCE THE AFTERNOON
IS ALL SAID AND DONE WITH THAT MOST IF NOT ALL LOCATIONS WILL
REACH OVER 105 DEGREES FOR HEAT INDICES. DID NOT CHANGE MUCH TO
THE CURRENT EXCESSIVE HEAT WARNINGS/HEAT ADVISORIES OTHER THAN
EXTEND THE HEAT ADVISORIES FOR AREAS SOUTH OF INTERSTATE 40
THROUGH SUNDAY EVENING. BELIEVE HEAT INDICES WILL BE A FEW
DEGREES LOWER ON SUNDAY AND NO EXCESSIVE HEAT WARNINGS WILL BE
NEEDED AS A COLD FRONT BEGINS TO ENTER THE MIDSOUTH.
SCATTERED SHOWERS AND THUNDERSTORMS WILL MOVE INTO THE MIDSOUTH
EARLY SUNDAY MORNING AS THE ABOVE MENTIONED COLD FRONT ENTERS THE
REGION. THINK THE BEST CHANCES FOR SHOWERS AND THUNDERSTORMS WILL
BE ACROSS WEST TENNESSEE AND NORTHEAST MISSISSIPPI SUNDAY
AFTERNOON. NOT CONFIDENT ON THE EXTENT OF THE COVERAGE BUT A
COUPLE OF STORMS COULD BECOME STRONG OR POSSIBLY SEVERE MAINLY
SOUTH OF INTERSTATE 40. HIGH TEMPERATURES WILL BE A FEW DEGREES
COOLER ON SUNDAY ESPECIALLY NORTH OF INTERSTATE 40 WITH THE
ADDITIONAL CLOUD COVER EXPECTED.
THE COLD FRONT WILL EXIT THE AREA SUNDAY NIGHT ALLOWING DRIER AIR
TO FILTER INTO THE REGION. UPPER LEVEL TROUGH WILL BEGIN SETTLING
OVER THE EASTERN HALF OF THE U.S. ON MONDAY ALLOWING THE MIDSOUTH
TO BE INFLUENCED BY NORTHWEST FLOW ALOFT AS WELL AS AT THE
SURFACE. HIGH TEMPERATURES WILL CONTINUE TO BE AROUND SEASONAL
NORMALS WITH HIGHS IN THE LOW 90S...BUT DEWPOINTS WILL SHARPLY
DROP OFF INTO THE LOW TO MID 60S ALLOWING HEAT INDICES TO
DECREASE. UPPER TROUGH WILL REMAIN OVER THE AREA THROUGH MIDWEEK
KEEPING DRY CONDITIONS AND SEASONAL TEMPERATURES OVER THE
MIDSOUTH. THE GFS IS ADVERTISING A FEW IMPULSES THAT MOVE ACROSS
THE REGION IN THIS NORTHWEST UPPER LEVEL FLOW FOR THE END OF THE
WORK WEEK BUT FOR NOW HAVE LEFT MOST OF THIS TIME FRAME RAIN FREE
AS PINPOINTING TIMING AND PLACEMENT IS TOO DIFFICULT.
KNS
&&
.AVIATION...
18Z TAFS
VERY WARM...HUMID AND UNSTABLE CONDITIONS WILL PREVAIL ACROSS THE
MIDSOUTH THIS AFTERNOON. THE UPPER LEVEL RIDGE CENTERED OVER TX
HAS NUDGED BACK EAST TODAY AND SHOULD SUPPRESS AFTERNOON THUNDERSTORM
DEVELOPMENT.
A COLD FRONT SHOULD DROP THROUGH THE MIDSOUTH IN THE 12Z TO 15Z TIME
FRAME. WOULD NOT RULE OUT A THUNDERSTORM OR TWO WITH THE FRONTAL
PASSAGE. GIVEN THE LIMITED COVERAGE...HAVE LEFT OUT OF THE TAFS.
