The episode as NWS MEG wrote it up.
The remnants of a previous outflow boundary interacted with an unstable atmosphere to trigger a lone severe thunderstorm across portions of northeast Arkansas during the late afternoon hours of June 16th.
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 Jun 16, 2:36 PM CST, 22 minutes earlier.
Area Forecast Discussion National Weather Service Memphis TN 336 PM CDT Sun Jun 16 2019 .DISCUSSION... A steamy afternoon across the Mid-South at this hour. Temperatures generally range from the upper 80s to 90 degrees. The hottest spot is currently West Memphis, AR where the heat index has crept into the triple digits over the past hour. Convection has been largely confined near an outflow boundary over over north Mississippi today. Storms have remained sub severe so far, with winds peaking around 40 mph with the strongest of cores. Latest KNQA radar shows storms just beginning to fire up to our west over east-central Arkansas. This activity is expected to push into northeast Arkansas and then lift through northwest Tennessee through this evening. A few storms could be strong to severe with damaging winds as the main threat. After sundown, most activity should come to an end. Monday through Wednesday... Broad upper level split flow will result in unsettled weather through this timeframe. The first of multiple shortwaves is progged to move through the region tomorrow afternoon and into the early morning hours on Tuesday. The best height falls will occur across the northern half of the area. The aforementioned area will have the best chance of strong to possibly a couple severe storms on Monday, with damaging winds as the main threat. Expect highs in the mid to upper 80s. A weak surface low will track across the Ozarks on Tuesday and stall a boundary out across the area. This will serve as a focus for storms on Tuesday. However, coverage should be a bit lower than Monday as heights will build behind the exiting wave by late afternoon. Another subtle shortwave will move into the Lower Mississippi Valley on Wednesday and spawn more widespread convection. Models are now hinting at yet another more pronounced shortwave pivoting through the area on Thursday in addition to a deepening surface low tracking near St. Louis. This wave will have more of a positive tilt to it, and a surface trough moving into the Mid- South. With quite a bit of instability and moderate dynamics, organized strong to severe storms are possible on Thursday. Will go ahead and add that to the HWO. Friday through next Weekend... We will finally see a brief break from the clouds and precipitation, but that means the heat will turn up on Friday. Heat indices will hit the triple digits west of the Mississippi River on Friday with upper 90s across the rest of the area. Would not be surprised if a couple of spots in northeast Arkansas meet 105F heat advisory criteria on Friday as a 590dm ridge builds in. By Saturday, the upper level pattern will become unsettled once again as a shortwave, embedded in southwest flow aloft, approaches the area from the west. Multiple waves will rotate through the Mid-South through early next week with good chances for showers and thunderstorms each day. AC3 && .AVIATION... 18Z TAFs Short term convection-allowing models (CAMs) continued to struggle with evolution of TSRA over the Arklamiss, into north MS this morning, often failing to initialize ongoing convection. 18Z MEM TAF delayed TSRA onset to 20Z, to account for possible development along the northwest flank of TSRA moving through north MS. Confidence not great however, given comparatively more stable appearance to the cumulus field on GOES visible imagery, and overlying convective cirrus from TSRA to south. PWB && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None. TN...None. &&
