The episode as NWS MEG wrote it up.
The Mid-South was underneath northwest flow aloft during the period between July 11th, 2010 and July 13th, 2010. Several upper level disturbances quickly moved through the flow setting off complexes of showers and thunderstorms. Some of these showers and thunderstorms became severe and produced damaging winds, large hail and flash flooding.

.DISCUSSION...
/ISSUED 335 AM CDT TUE JUL 13 2010/
HUGE MESOSCALE CONVECTIVE SYSTEM MOVING INTO THE CWA AT THIS
TIME. THE AREA OF SHOWERS AND THUNDERSTORMS HAVE DEVELOPED OUT
AHEAD OF AN APPROACHING SHORTWAVE CURRENTLY OVER SOUTHWEST
MISSOURI. THE SHORTWAVE IS FORECASTED TO BE OVER MEMPHIS BY 18Z.
THUS THE BEST CHANCES FOR RAIN WILL OCCUR UP UNTIL THIS TIME AND
WILL LIKELY OCCUR FROM THIS MCS. THE MCS WILL LIKELY BEGIN TO DIE
AROUND SUNRISE. HOWEVER REMNANTS FROM THE MCS WILL CONTINUE TO
PUSH EAST OVER THE CWA THROUGH THE COURSE OF THE MORNING.
REDEVELOPMENT AHEAD OF THE SHORTWAVE MAY OCCUR ACROSS EASTERN
SECTIONS OF THE CWA DURING THE AFTERNOON. CAN/T RULE OUT ISOLATED
SHOWERS AND THUNDERSTORMS OCCURRING BEHIND THE SHORTWAVE THUS WILL
KEEP 20 POPS FOR WESTERN SECTIONS OF THE CWA. THREAT FOR HEAVY
RAIN WILL OCCUR WITH THE MCS THUS FLASH FLOOD WATCH THROUGH 18Z
LOOKS GOOD. WILL LIKELY BE ABLE TO CANCEL PORTIONS OF THE WATCH
EARLY AS THE MCS MOVES EAST OR WEAKENS WITH TIME. HIGHS WILL BE IN
THE UPPER 80S TO MID 90S.
TONIGHT THROUGH THURSDAY...UPPER RIDGE BUILDS OVER THE MIDSOUTH. THE
RIDGE WILL BE THE STRONGEST WEDNESDAY AFTERNOON INTO WEDNESDAY
EVENING BEFORE WEAKENING AGAIN ON THURSDAY. RECENT HEAVY RAINFALL IN
ADDITION TO WHAT WILL FALL THIS MORNING WILL PROVIDE FOR HIGH
HUMIDITY VALUES OVER THE REGION. DEWPOINTS WILL LIKELY STAY IN THE
MID 70S. HOWEVER...THE ABUNDANT MOISTURE IN THE ATMOSPHERE WILL KEEP
TEMPERATURES FROM WARMING AS HIGH AS WHAT GUIDANCE VALUES ARE
PREDICTING. HIGHS WILL LIKELY STAY IN THE MID 90S AS OPPOSE TO UPPER
90S OR 100 DEGREES THAT GUIDANCE IS PREDICTING. THIS WILL KEEP
HEAT INDICES BELOW 110 DEGREES BUT STILL BETWEEN 105 AND 109
DEGREES. HEAT INDICES WEDNESDAY WILL LIKELY BE BETWEEN 105 AND 107
DEGREES WITH SLIGHTLY HIGHER READINGS ON THURSDAY DUE TO SLIGHTLY
WARMER HIGHS. THURSDAYS INDICES WILL LIKELY BE BETWEEN 107 AND 109
DURING THE AFTERNOON. THESE INDICES WILL STILL BE DANGEROUS TO
PEOPLE THAT ARE AT RISK FOR DEVELOPING HEAT ILLNESSES. WILL
CONVERT THE EXCESSIVE HEAT WATCH TO A HEAT ADVISORY FOR WEDNESDAY
AND THURSDAY. LOWS WILL STAY IN THE MID TO UPPER 70S. ISOLATED
DAYTIME SHOWERS AND THUNDERSTORMS COULD OCCUR AS WELL BUT AT THIS
POINT NOT ENOUGH TO THROW IN A 20 POP.
THURSDAY NIGHT INTO FRIDAY NIGHT...A COLD FRONT WILL APPROACH THE
MIDSOUTH. MODELS DIFFER SOMEWHAT ON TIMING. CONSENSUS SHOWS FRONT
WILL BE MOVING INTO THE CWA BY FRIDAY NIGHT. CHANCES FOR SHOWERS AND
THUNDERSTORMS WILL OCCUR ALONG THE FRONT WITH BEST CHANCES OCCURRING
FRIDAY NIGHT. IN ADDITION...DEPENDING ON THE LOCATION OF THE FRONT OF
FRIDAY...HIGHER DEWPOINTS COULD POOL AHEAD OF THE FRONT CREATING A
RISK FOR HIGHER HEAT INDICES THAN WEDNESDAY OR THURSDAY. ALTHOUGH
THE ONE CAVEAT THAT COULD OCCUR WOULD BE THAT CLOUD COVER AND
THUNDERSTORMS COULD KEEP TEMPERATURES COOLER THAN THE MID 90S. WILL
HAVE TO MONITOR.
SATURDAY INTO MONDAY...FRONT WILL WASH OUT OVER THE AREA AS UPPER
RIDGE BEGINS TO BUILD BACK OVER THE AREA. SCATTERED SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE ON SATURDAY BUT BY SUNDAY AND MONDAY
COVERAGE SHOULD RETURN TO ISOLATED AS CONVECTION WILL ONLY OCCUR
FROM DAYTIME HEATING. EXPECT HIGHS IN THE LOWER TO MID 90S WITH LOWS
IN THE 70S.

.AVIATION...
12Z TAFS
CURRENT SHRA/TSRA WILL AFFECT KMEM AND KMKL THROUGH 16 OR
17Z...THEN KTUP 14-18Z. THINK ACTIVITY WILL STAY SOUTH OF KJBR.
GENERALLY EXPECT VARYING CONDITIONS BETWEEN VFR AND MVFR IN THIS
SHRA/TSRA WITH THE WORST CONDITIONS MAINLY ALONG THE LEADING EDGE
WHERE BRIEF IFR CONDITIONS ARE POSSIBLE...THEN IMPROVING
CONDITIONS BEHIND THE MAIN LEADING EDGE OF SHRA/TSRA.
18-06Z...EXPECT VFR CONDITIONS AT ALL SITES. THINK ALL SHRA/TSRA
WILL BE EAST OF THE AREA. WOULD NOT BE SURPRISED IF SOME MVFR
CONDITIONS LINGERED 18-22Z AT ANY SITE...PARTICULARLY NEAR
KTUP...BUT WENT OPTIMISTIC IN FORECAST THINKING VFR CONDITIONS
WILL PREVAIL.
AFTER 06Z...WILL MONITOR FOR MVFR CONDITIONS OR LOWER IN FOG AT
KMKL...KJBR...AND KTUP. ADDED MVFR AT THESE SITES AND IFR
CONDITIONS AT KMKL AFTER 10Z WHERE CONFIDENCE OF FOG DEVELOPMENT
IS HIGHEST.
WINDS MAY BE LOCALLY GUSTY NEAR SHRA/TSRA THIS MORNING...BUT
GENERALLY BETWEEN THE SOUTH AND WEST AND 8 KTS OR LOWER.
