The episode as NWS MEG wrote it up.
An upper level disturbance spawned one lone severe thunderstorm across portions of southwest Tennessee during the overnight hours of July 8th.
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 Jul 7, 10:18 PM CST, 2 hours 10 minutes earlier.
Area Forecast Discussion National Weather Service Memphis TN 1118 PM CDT Fri Jul 7 2017 .UPDATE...Aviation Discussion. && .PREV DISCUSSION... /issued 906 PM CDT Fri Jul 7 2017/ Skies are mostly clear this evening across the forecast area with temperatures ranging from the upper 70s to mid 80s. A few strong to severe thunderstorms are moving over south central Missouri at this time and this activity will be moving into northeast Arkansas in the next hour or so. These storms will be monitored for the potential of having damaging winds and possibly some large hail. This activity may press through much of the forecast area overnight so have added PoPs to southern sections of the forecast area. ARS && .PREV DISCUSSION... /issued 248 PM CDT Fri Jul 7 2017/ Currently skies were mostly sunny with generally light winds. Temperatures ranged from the mid 80s along the Tennessee River to near 90F in the Delta. For tonight through Sunday...short term model solutions show approaching weak cold front to enter the CWA late this evening...with scattered storms draped along it through roughly sunrise tomorrow morning as it reaches the TN/MS state line. A few of the storms may reach strong intensity through the night. A lull in activity is anticipated mid to late tomorrow morning...with the far southern counties running the greatest risk for rain throughout the afternoon. Farther north more sun will keep high temperatures fairly close to what is being observed today...but dewpoints will fall into the 60s providing for lower humidity. By Sunday the entire Midsouth will reap the lower humidity benefit with overall dry weather anticipated. Monday through next Friday...the Midsouth will be dominated by upper level high pressure with the GFS and ECMWF building heights to near 595DM over the Ozarks and Mid Mississippi Valley. This typical summer pattern for our area will warm temperatures a couple of degrees/low and mid 90s...with dewpoints creeping back up to the low 70s. Heat indices will reach the 100F to 105 range...which could prompt a heat advisory for portions of the area. Cumulus clouds will provide some shade and afternoon convection coverage from the models still appears isolated...and mainly in the east where capping from the high will not be as strong. By the end of the week the high center will begin retrograding back to the Rockies as the jet stream dips across the Great Lakes. This may allow for greater rain chances over the entire area next weekend. JAB && .AVIATION...06z TAF Cycle VFR conditions will prevail tonight and tomorrow. A cold front will result in a wind shift early tomorrow. North Winds will increase to around 10-15kt with higher gusts. Short term guidance and radar trends show ongoing thunderstorms weakening as they approach JBR. Will include a 2hr TEMPO group for thunderstorms. 30 && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None.
