The radar
The Memphis radar (KNQA), 129 km from the middle of the area, began a volume at 22:25 UTC, the scan nearest the moment this went out.
Open the radar archive at this moment
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 (KLZK), launched 12:00Z, 10.4 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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
347 PM CDT THU JUL 19 2012
.DISCUSSION...
.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT.
INTENSE HEAT HAS RETURNED TODAY WITH SEVERAL LOCATIONS OVER NERN
AR AND THE BOOTHEEL EXCEEDING 100 DEGREES. IN FACT...AT 3 PM
JONESBORO HAS REACHED AN IMPRESSIVE 105 DEGREES WITH MID 100S
EXTENDING TO THE SOUTHWEST FROM THERE. COOLER AIR TEMPERATURES
CAN BE FOUND TO THE SOUTHEAST OVER NERN MS...BUT DEW POINTS ARE
EXTREMELY OPPRESSIVE AND ARE APPROACHING 80 DEGREES IN SOME SPOTS
DOWN THERE...THUS THE DIFFERENCE IN HEAT INDEX AROUND THE AREA IS
ONLY A FEW DEGREES. OBVIOUSLY DECIDED TO EXPAND THE HEAT ADVISORY
ACROSS THE REST OF THE CWA FOR THIS AFTERNOON AND TONIGHT.
CONVECTION THIS AFTERNOON HAS BEEN RATHER UNIMPRESSIVE DUE TO THE
STABLE AIRMASS LEFT BEHIND FROM OUTFLOWS LAST NIGHT. HOWEVER...
ACTIVITY IS BEGINNING TO INCREASE IN COVERAGE AND INTENSITY OVER
ERN AR...NRN MS...AND SERN MO AS THE CAP FINALLY ERODES. THINK
THIS TREND WILL CONTINUE INTO THE EVENING WITH THE POTENTIAL FOR
ADDITIONAL ACTIVITY TO FORM ALONG THE FRONT THIS EVENING AS IT
SAGS SOUTH FROM SRN MO. MAINTAINED NEAR 50 POP FOR TONIGHT ACROSS
THE ENTIRE AREA...WHICH MAY NEED TO BE ADJUSTED WHEN IT BECOMES
CLEAR HOW EXISTING OUTFLOW BOUNDARIES CONTRIBUTE TO THE COVERAGE.
A FEW SEVERE STORMS WILL BE POSSIBLE WITH DAMAGING WINDS.
THE FRONT WILL SAG SOUTH INTO NRN MS FRIDAY...REDUCING POPS FROM
NORTH TO SOUTH. THERE ARE TWO CONCERNS FOR FRIDAY. ONE BEING HIGHS
AND DEW POINTS...AND THE OTHER BEING SEVERE WX POTENTIAL ALONG AND
AHEAD OF THE FRONT.
HIGH TEMPERATURES WILL BE HOT...QUESTION IS HOW HOT. THIS IS A
FAVORABLE PATTERN FOR 100 DEGREE DAYS OVER THE DELTA AS DRIER AIR
FEEDS IN ON NORTH WINDS AS THE THERMAL RIDGE LAGS ALONG AND BEHIND
THE SURFACE FRONT. COULD SEE SOME AREAS EXCEED 103 DEGREES AGAIN
TOMORROW...PARTICULARLY ALONG I-40 AND WEST OF I-55 WHERE THE 925
MB THERMAL RIDGE IS EXPECTED TO BE LAID OUT AROUND 21Z. THINK THE
MAV TEMPERATURES ARE EMBARRASSINGLY LOW SO DISREGARDED THEM
COMPLETELY. WENT SLIGHTLY HIGHER THAN A BLEND OF MET AND EURO.
DEW POINTS AGAIN WILL BE HIGH ALONG AND AHEAD OF THE FRONT WITH
SIGNIFICANT POOLING POSSIBLE. DESPITE HIGHS ONLY IN THE LOW TO MID
90S OVER LOCATIONS NEAR THE TN RIVER AND NERN MS...DEW POINTS WILL
AGAIN BE IN THE MID/UPPER 70S YIELDING HEAT INDICES AOA 105
DEGREES. FURTHER NORTHWEST...IT IS HARD TO SAY HOW MUCH DEW POINTS
WILL MIX BUT THINK THEY SHOULD REMAIN AT LEAST IN THE UPPER 60S.
THUS...ISSUED A HEAT ADVISORY FOR THE ENTIRE MIDSOUTH THROUGH 7 PM
FRIDAY. COULD SEE SOME LOCATIONS JUST BEHIND THE FRONT NEAR I-40
REMAINING HIGH ON DEW POINTS /MID 70S/...JUXTAPOSED WITH
TEMPERATURES EXCEEDING 100 /INCLUDING MEMPHIS/. IN THAT CASE...AN
UPGRADE TO AN EXCESSIVE HEAT WARNING WILL BE NEEDED.
THINK THE SEVERE THREAT FRIDAY WILL BE CONFINED INTO THE
SOUTHEASTERN-MOST COUNTIES. HERE...SBCAPE VALUES OF 4000 TO 5000
J/KG WILL BE OBTAINED FROM POOLING DEW POINTS AND DRYING MID
LEVELS.STRENGTHENING MID LEVEL FLOW ASSOCIATED WITH THE APPROACH
OF THE FRONT SHOULD PROVIDE ENOUGH SHEAR FOR AT LEAST SOME
ORGANIZATION OF STORM CLUSTERS OR LINE SEGMENTS CAPABLE OF WIND
DAMAGE...ALTHOUGH WITH THE DRYING MID LEVELS HAIL WILL ALSO BE
POSSIBLE.
DRIER AIR WILL ARRIVE SATURDAY...BUT TEMPERATURES WILL STILL
REMAIN ABOVE AVERAGE AS THE MID LEVEL RIDGE REMAINS IN PLACE OVER
THE MID MISSISSIPPI VALLEY. THE DRIER AIR SHOULD MITIGATE THE NEED
FOR ANOTHER HEAT ADVISORY.
.LONG TERM...SUNDAY THROUGH THURSDAY.
WEAK CONVERGENCE AND A LESSER INFLUENCE OF THE SEMI-PERMANENT 2012
RIDGE OVER NERN MS WILL ALLOW FOR SMALL CHANCES FOR STORMS EACH
DAY THROUGH TUESDAY. FURTHER NORTHWEST...NO LIFTING MECHANISMS AND
THE RIDGE SHOULD KEEP THE RISK AT BAY.
EURO SHOWS THE RIDGE EXPANDING FOR MID/LATE WEEK...WITH TEMPERATURES
INCREASING BACK TOWARD OR EXCEEDING 100. DEW POINTS MAY CREEP BACK
INTO THE LOWER 70S AND HEAT HEADLINES MAY BE NEEDED AGAIN AT SOME
POINT LATER NEXT WEEK.

.AVIATION...
18Z TAFS
OUTFLOW BOUNDARY THAT MOVED THROUGH THE MIDSOUTH LAST EVENING FROM
THE EAST HAS RESULTED IN AN INITIALLY MORE STABLE LOWER ATMOSPHERE
TO START THE 18Z TAF PERIOD. THE REMNANTS OF THIS BOUNDARY EXTENDED
FROM NEAR TUP...WESTWARD TO 50SM SOUTH OF MEM... TO 70SM SW OF JBR.
BEST TSRA CHANCE WILL BE OVER NORTH MS... SOUTH OF MEM THIS
AFTERNOON. ISOLATED TSRA WILL BE POSSIBLE BEHIND THIS BOUNDARY...
INCLUDING NEAR MEM AFTER 20Z...ONCE CONVECTIVE TEMPS ARE REACHED.
12Z NAM AND 13Z HRRR MODELS SUGGEST A SECONDARY BANDED AREA OF
SHRA/TSRA MOVING SOUTH THROUGH MEM IN THE 01Z TO 03Z TIME FRAME.
THIS ACTIVITY WOULD BE A SOUTHERN PROGRESSION OF PREFRONTAL
SHRA/TSRA THAT WAS OBSERVED ACROSS SOUTH CENTRAL MO AT MIDDAY.
THERE IS SOME DOUBT WHETHER FORCING WILL BE SUFFICIENT TO
OVERCOME A STRENGTHENING CONVECTIVE CAP FOLLOWING SUNSET. GIVEN
MODEL CONSENSUS...HAVE INCLUDED A SHORT TEMPO FOR EARLY EVENING
PERIOD AT MEM.
