The episode as NWS TSA wrote it up.
Thunderstorms developed across portions of eastern Oklahoma during the afternoon hours of the 30th and moved into northwestern Arkansas during the evening. The strongest storms produced damaging wind in Sebastian County.
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 Tulsa, OK wrote its last area forecast discussion before the first event at Aug 30, 1:53 PM CST, 3 hours 33 minutes earlier.
Area Forecast Discussion National Weather Service Tulsa OK 253 PM CDT Thu Aug 30 2018 .DISCUSSION... Area of convection remains ongoing across parts of northeast Oklahoma with another area exiting northwest Arkansas. Outflow boundary generated from the aforementioned convection showing up nicely on KINX, however current thinking is chances for additional storm development along this boundary will be quite limited as upper level high pressure continues to build into the area from the south. That said, convective chances look to be confined to the same areas for the remainder of the afternoon. Expect diminishing coverage around 00Z across far northwest Arkansas, so at this time will not include pops for the first period, but instead use a pre first period to keep a mention going through the afternoon. Upper level high pressure will build into the area for Friday and Saturday, likely resulting in the hottest days for this forecast cycle. Much of the area will see afternoon heat index values between 100-105 Friday, with the potential for a few degrees less for Saturday. The upper high begins to shift east late in the weekend, leaving the area on the periphery of slightly better flow. Several disturbances moving around the periphery of the high will increase chances for scattered thunderstorms, mainly during the afternoon beginning Sunday and continuing into Labor Day. The pattern into the middle of the week doesn't look to change much, so will maintain low pops across the entire area with warm and humid conditions to continue. && .PRELIMINARY POINT TEMPS/POPS...
