The episode as NWS MEG wrote it up.
An upper level disturbance moved through the Mid-South during the afternoon and early evening hours of July 14th, 2014. The disturbance interacted with a warm and unstable airmass which helped to set off numerous showers and thunderstorms. Some storms became severe producing damaging winds and flash flooding.

NWS Memphis, TN wrote its last area forecast discussion before the first event at Jul 14, 11:48 AM CST, 1 hour 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MEMPHIS TN 1248 PM CDT MON JUL 14 2014 .UPDATE... && .DISCUSSION... && .PREV DISCUSSION... /ISSUED 944 AM CDT MON JUL 14 2014/ UPDATE... UPDATED ZONES AND GRIDS HAVE BEEN SENT TO MAKE A FEW TWEAKS FOR THIS AFTERNOON. INCREASED THE POPS SLIGHTLY ACROSS MOST OF NORTHEAST AR...WEST TN AND THE MO BOOTHEEL FOR THIS AFTERNOON. ALSO RAISED THE HIGH TEMPERATURES A DEGREE OR TWO SOUTH OF INTERSTATE 40. H5 ANALYSIS THIS MORNING SHOWED A STRONG CLOSED LOW PUSHING INTO MN AND WI WITH A BROAD TROUGH EXTENDING INTO THE CENTRAL PLAINS. AN ASSOCIATED STRONG COLD FRONT EXTENDED FROM NORTHERN IL THROUGH NORTHERN MO INTO NORTHEASTERN KS. A PREFRONTAL TROUGH WAS ACROSS SOUTHEASTERN MO. IN ADDITION...OUTFLOW BOUNDARIES EXTEND ACROSS WEST TN AND NORTHEAST AR FROM THE CONVECTION EARLIER THIS MORNING. THE ATMOSPHERE IS FORECAST TO BECOME VERY UNSTABLE THIS AFTERNOON AS THE COLD FRONT AND PREFRONTAL TROUGH PUSH SOUTHEASTWARD. THE COLD FRONT IS FORECAST INTO SOUTHEASTERN MO BY EARLY EVENING. MODELS INDICATE THAT THUNDERSTORMS ACROSS NORTHWEST TN WILL PUSH EAST SOUTHEAST OUT OF THE AREA THIS MORNING WITH NEW CONVECTION FIRING UP BEGINNING EARLY TO MID AFTERNOON...ESPECIALLY ACROSS WEST TN...NORTHEAST AR AND THE MO BOOTHEEL. A FEW STORMS WILL BECOME SEVERE WITH DAMAGING WINDS AND LARGE HAIL AS LIFTED INDICES DECREASE TO BETWEEN MINUS 8 AND MINUS 9...AND MIXED LAYER CAPES INCREASE TO BETWEEN 4000 AND 5000 J/KG. LOCALLY HEAVY RAINFALL WITH LOCALIZED FLASH FLOODING IS ALSO POSSIBLE AS PRECIPITABLE WATER VALUES INCREASE TO NEAR 2.3 INCHES AND SURFACE DEW POINTS ARE IN THE LOWER AND MIDDLE 70S. VERY HOT AIR IS FORECAST TO PUSH ITO THE AREA AHEAD OF THE CONVECTION MAINLY ALONG AND SOUTH OF INTERSTATE 40...925 MB TEMPERATURES WERE NEAR 26 DEGREES CELSIUS ON THE 12Z LITTLE ROCK SOUNDING. JCL DISCUSSION... /ISSUED 322 AM CDT MON JUL 14 2014/ AN UNSEASONABLY STRONG UPPER LEVEL LOW PRESSURE SYSTEM CURRENTLY POSITIONED OVER THE ARROWHEAD OF MINNESOTA WILL CONTINUE TO DROP SOUTHEAST OVER THE NEXT FEW DAYS ACROSS THE GREAT LAKES. MID LEVEL HEIGHT FALLS WILL CONTINUE OVER THE AREA TODAY AS THE LOW LEVEL AIRMASS REMAINS VERY WARM AND MOIST. THIS SHOULD HELP TO INCREASE INSTABILITY OVER THE REGION WITH LATEST MODEL GUIDANCE SUGGESTING THAT MLCAPES WILL EXCEED 3000 J/KG IN MOST AREAS ALONG WITH LI/S OF LESS THAN -6C. THIS INCREASED INSTABILITY SHOULD ALLOW FOR NUMEROUS SHOWERS AND THUNDERSTORMS TO DEVELOP OVER AREAS ALONG AND NORTH OF INTERSTATE 40 TODAY...WITH SCATTERED COVERAGE FURTHER SOUTH. IN ADDITION TO THE INCREASED INSTABILITY...DEEP LAYER SHEAR SHOULD BECOME ENHANCED ALONG THE SOUTHERN PERIPHERY OF THE LARGE UPPER TROUGH OVER OUR REGION. THIS COMBINATION OF SHEAR AND INSTABILITY SHOULD BECOME FAVORABLE TO SUPPORT MULTICELL CLUSTERS AND LINE SEGMENTS ACROSS THE REGION. THESE ORGANIZED STORM CLUSTERS MAY BECOME SEVERE AND PRODUCE DAMAGING WINDS AND POTENTIALLY SOME LARGE HAIL. THE UPPER LOW WILL CONTINUE TO DIG SOUTHEAST TONIGHT AND HELP TO FORCE A STRONG COLD FRONT SOUTHWARD ACROSS THE REGION. NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE ALONG AND AHEAD OF THE FRONT OVERNIGHT. SEVERE THUNDERSTORMS WILL REMAIN POSSIBLE OVERNIGHT AS THE ATMOSPHERE REMAINS UNSTABLE AND DEEP LAYER SHEAR INCREASES FURTHER. DAMAGING WINDS SHOULD REMAIN THE PRIMARY THREAT TONIGHT. THE COLD FRONT SHOULD REACH THE INTERSTATE 40 CORRIDOR BY SUNRISE TUESDAY AND PUSH THROUGH THE REMAINDER OF THE FORECAST REGION BY EARLY AFTERNOON. NUMEROUS SHOWERS AND THUNDERSTORMS SHOULD CONTINUE ACROSS SOUTHERN AREAS TUESDAY MORNING WITH QUICKLY TAPERING POPS FURTHER NORTH AND WEST BEHIND THE FRONT. MOST AREAS SHOULD DRY OUT BY LATER TUESDAY AFTERNOON AS COOLER AND MUCH LESS HUMID CONDITIONS BUILD OVER THE REGION IN ASSOCIATION WITH A BUILDING CANADIAN SURFACE HIGH PRESSURE SYSTEM. CANADIAN HIGH PRESSURE WILL SETTLE OVER THE MID SOUTH ON WEDNESDAY WITH WELL BELOW NORMAL TEMPERATURES AND DRY CONDITIONS. HUMIDITY LEVELS WILL ALSO BE UNSEASONABLY LOW LEADING TO VERY PLEASANT MID SUMMER WEATHER CONDITIONS. THE COLD FRONT TO OUR SOUTH WILL STALL OUT IN THE VICINITY OF THE INTERSTATE 20 CORRIDOR IN SOUTH CENTRAL MISSISSIPPI AND NORTHERN LOUISIANA THROUGH WEDNESDAY NIGHT. ANOTHER POTENT UPPER LEVEL SHORTWAVE WILL DIG ACROSS THE PLAINS STATES WEDNESDAY NIGHT AND THURSDAY BEFORE MOVING SLOWLY EAST THROUGH THE END OF THE WEEK. THIS SHOULD HELP TO LIFT THE FRONT TO OUR SOUTH BACK TO THE NORTH AS A WARM FRONT. ABUNDANT GULF MOISTURE WILL BEGIN TO OVERRUN THE FRONT BY LATE WEDNESDAY NIGHT INTO THURSDAY. INCREASING CHANCES FOR RAIN AND ELEVATED THUNDERSTORMS CAN BE EXPECTED FROM SOUTH TO NORTH ON THURSDAY THROUGH THURSDAY NIGHT. BY FRIDAY...THE FRONT SHOULD BE STRETCHED ACROSS THE REGION WITH A SURFACE WAVE OF LOW PRESSURE FORECAST TO LIFT NORTHEAST ALONG THE FRONT ACROSS THE MID SOUTH. THIS MAY ENHANCE PRECIPITATION OVER THE REGION WITH THE POTENTIAL FOR NUMEROUS SHOWERS AND THUNDERSTORMS ALONG WITH AN INCREASING THREAT FOR HEAVY RAINFALL AND POSSIBLE FLASH FLOODING. THIS THREAT WILL BE CLOSELY MONITORED OVER THE NEXT SEVERAL FORECAST CYCLES. THE SHORTWAVE SHOULD BECOME ELONGATED ACROSS THE AREA ON SATURDAY AS THE FRONT SHIFTS FURTHER SOUTHEAST. THIS SHOULD ALLOW FOR A CONTINUATION OF SCATTERED SHOWERS AND THUNDERSTORMS OVER THE REGION. THE SHORTWAVE TROUGH SHOULD LIFT OUT BY SUNDAY WITH THE FRONT WASHING OUT. ISOLATED SHOWERS AND THUNDERSTORMS SHOULD CONTINUE AS THE AIRMASS REMAINS INCREASINGLY WARM...MOIST...AND UNSTABLE. NORTHWESTERLY FLOW ALOFT SHOULD DEVELOP AGAIN BY EARLY NEXT WEEK WITH A SERIES OF SHORTWAVE DISTURBANCES MOVING THROUGH THE FLOW ALOFT. THIS SHOULD SUPPORT A CONTINUATION OF AN OVERALL WETTER PATTERN AND CONTINUED CHANCES FOR SHOWERS AND THUNDERSTORMS THROUGH THE EXTENDED FORECAST PERIOD. THIS PATTERN ALSO SUPPORTS BELOW NORMAL TEMPERATURES AND INCREASED HUMIDITY LEVELS. JLH AVIATION... 18Z TAF CYCLE TS NOW BUILDING IN BOOTHEEL. CURRENT THINKING IS THAT JBR, MEM, MKL TO BE IN VCTS IN A COUPLE OF HOURS. TUP TO GET INTO VCTS LATER THIS AFTERNOON. HAIL AND WINDSTORMS ARE THE MAIN THREAT AROUND THESE EAST MOVING STORMS. WINDS TO VEER AT NORTHERN APTS FIRST...THEN VEERING IN MEM AND MKL. CEILING TO DROP AS THE FROM COMES IN. STORMS SHOULD BE OUT OF AREA TMR MORN. && .AVIATION... && .MEG WATCHES/WARNINGS/ADVISORIES...
