The episode as NWS OHX wrote it up.

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Nashville, TN wrote its last area forecast discussion before the first event at May 27, 11:44 AM CST, 43 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NASHVILLE TN 1244 PM CDT WED MAY 27 2015 .UPDATE...FOR 18Z AVIATION. && .AVIATION...18Z TAF DISCUSSION. SCATTERED TS THIS AFTERNOON HAS WARRANTED SEVERAL HOURS OF TEMPOS AT EACH MID-STATE TERMINAL. SOME REDUCED FLIGHT CATEGORIES FOR SHORT PERIODS WITH THE HEAVIER RAINS. BIGGER STORY WILL LIKELY BE THE FOG OVERNIGHT AS WINDS GO CALM AND THOSE WHO SEE RAIN TODAY HAVE VISIBILITIES FALL OFF. IFR TO LIFR AND LOWER CATEGORIES WILL BE LIKELY TONIGHT. WINDS WILL BE LIGHT FOR THE MOST PART...WITH BREEZY CONDITIONS IN AND AROUND PASSING TS. UNGER && .PREV DISCUSSION... /ISSUED 911 AM CDT WED MAY 27 2015/ UPDATE...FOR MORNING DISCUSSION. DISCUSSION... WITH THE CURRENT TRENDS IN THE LATEST HI-RES GUIDANCE AND ACTIVITY UPSTREAM FROM THE MID-STATE...A FAIRLY SUBSTANTIAL BUMP IN DAYTIME POPS LOOKS WARRANTED. AN EXPANDING COMPLEX OF SHOWERS AND THUNDERSTORMS ON THE ARK-MS STATE LINE LINE...CURRENTLY SPREADING NORTHWARD INTO NORTHERN MS AND SOON...WEST TN...WILL CLOSE IN ON OUR SOUTHWESTERN COUNTIES LATE THIS MORNING. BY THIS AFTERNOON... THIS ACTIVITY SHOULD SPREAD ACROSS THE REST OF MIDDLE TN BRINGING WIDESPREAD SHOWERS AND TS TO THE WHOLE AREA. THE QUESTION IS...HOW STRONG WILL THEY BECOME. DEW POINTS ARE FIRMLY IN THE UPPER 60S AND THIS WILL NOT CHANGE...BUT THE CURRENT CLOUD COVER COULD HAMPER MUCH OF THE DESTABILIZATION WE COULD REALIZE. STILL... 1500-2000 J/KG IS A LIKELY NUMBER FOR US. COUPLED WITH THE DRY AIR THAT WAS BEING SHOWN ON THE 12Z OHX SOUNDING...THE WIND THREAT WILL LIKELY BE A LITTLE HIGHER THAN IT WAS YESTERDAY. I THINK THE BIGGER THING WE WILL NEED TO PAY ATTENTION TO IS THE SLOW MOVING NATURE OF THESE STORMS. ALONG WITH THE DRY AIR ALOFT...THIS MORNING'S SOUNDING IS ALSO SHOWING ONLY 13 KTS OF FORWARD MOTION. WHILE OUR FLASH FLOOD GUIDANCE IS A LITTLE HIGHER THAN MOST OF OUR SURROUNDING WFOS...RAIN RATES OF 1 TO 2 INCHES AN HOUR WITH SLOW MOTION COULD PRODUCE A LOCALIZED FLASH FLOOD THREAT THIS AFTERNOON THAT WE WILL NEED TO MONITOR. UPDATES ARE ALREADY OUT. UNGER && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && 27
