The episode as NWS MEG wrote it up.
A descending upper level disturbance from the Lower Missouri River Valley interacted with a very unstable environment throughout the Midsouth producing severe thunderstorms across portions of northwest Tennessee during the evening hours of August 6th.
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 Memphis, TN wrote its last area forecast discussion before the first event at Aug 6, 5:16 PM CST, 2 hours 44 minutes earlier.
Area Forecast Discussion National Weather Service Memphis TN 616 PM CDT Tue Aug 6 2019 .UPDATE... Updated to include 00z Aviation Discussion. && .PREV DISCUSSION... /issued 400 PM CDT Tue Aug 6 2019/ DISCUSSION... Diurnal isolated thunderstorms are developing across the forecast area this afternoon. Expect the isolated storms to dissipate by early this evening. However, a developing MCS over the middle Mississippi valley will move south-southeastward into a portion of west Tennessee later this evening into the overnight hours. A nearly stationary front will remain over the region over the next several days. An upper ridge over west TX and a trough over the eastern US will continue to support a NW flow aloft favoring additional storms from MCSs into the weekend. The western upper ridge will migrate eastward toward the lower Mississippi valley Sunday into early next week. This will decrease the chance of storms but increase the heat potential later in the weekend into next week. SWC && .AVIATION... 00Z TAFs Patchy fog may produce temporary MVFR/IFR conditions at MKL overnight towards sunrise. Otherwise, VFR conditions expected through the period. VCTS possible through 07Z at MKL and at TUP for the next 2-3 hours. VCTS possible at MEM/TUP on Wednesday afternoon. Light winds tonight gradually anticipated to veer NW towards Wednesday morning.
