The episode as NWS SHV wrote it up.
An upper level ridge of high pressure was anchored over the Central Plains during the afternoon of July 6th, with weak impulses aloft in the easterly flow interacting with strong diurnal heating to generate isolated to widely scattered showers and thunderstorms across Southwest Arkansas, North Louisiana, East Texas, and Southeast Oklahoma. Given the strong instability that had developed that afternoon, some of these storms became severe, which resulted in damaging winds which downed several trees across portions of Southwest Arkansas before the storms diminished during the evening with the loss of heating.
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 Shreveport, LA wrote its last area forecast discussion before the first event at Jul 6, 1:48 PM CST, 3 hours 27 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 248 PM CDT Fri Jul 6 2018 .SHORT TERM... Scattered convection quickly erupted across ne TX around noon with cells quickly movg to the west as our area located in the se sector of large upper ridge over central high plains. In this scenario, any cell will produce stg gusty winds and larger storms can easily produce damaging wind gusts. More isold cells covering entire remainder of cwa. Backdoor cold front still well north over mid mississippi river valley with considerable dewpoint pooling seen south of front. As this front and moisture convergence makes its way towards area this weekend, expect greater coverage of storms into the wknd. Will see relief from daytime highs as high temps this wknd either side of 90 degrees depending on sky cover in the aftn./07/. LONG TERM.../Sunday through Friday Night/ The end of the weekend into much of next week will remain unsettled across our region which as far as rainfall goes is good news. Expansive upper ridging will dominate much of the center of the country, extending from the Four Corners Region through the upper midwest and into the Ohio Valley. Weak troughing will exist to the south of this ridge axis, or across our region of the country and thus we will maintain good chances for rain into early next week. By the middle and latter half of the work week, the eastern flank of this ridge axis appears to get replaced by a trough of low pressure aloft that will extend from New England southward across the Appalachian chain but there will remain a strong shear axis in place across our region which will continue to focus at least scattered diurnally driven convection across portions of our region each day. Did not stray too far from MOS temps concerning overnight lows or daytime highs but did raise Max temps a few degrees towards the later extended periods. 13 && .PREV DISCUSSION... /issued 104 PM CDT Fri Jul 6 2018/ AVIATION... Scattered convection has rapidly begun to develop across the general Interstate corridor region of ne TX and nw La. Vcnty tstms currently at kshv, kggg, and ktyr, and can be expected areawide this aftn. Expect a similar day to yesterday with storms tracking from the e-ne with gusty winds of 40+ kts possible in larger cells which will diminish by sunset. Mostly vfr conditions with ne winds becmg lgt overnight. A weak frontal boundary will slowly approach area Saturday, with convection possibly increasing even more just after the end of the 07/18z fcst cycle./07/. PREV DISCUSSION... /issued 1131 AM CDT Fri Jul 6 2018/ UPDATE... Late morning temps rising to upper 80s to around 90. Have bumped up temps a degree or two at some locations, and expect aftn highs mainly in upper 90s given trends as well as looking back at yesterday. Dewpoints not mixing out much so far and mainly in middle 70s. So although heat advisory criteria will be met for much of the area today, a not so hot Saturday will negate the 2 consecutive day criteria met issuance of heat advisory. Have adjusted aftn pops to a more smooth chance category. However, do expect any storms that develop to move sewd in deep ne flow, similar to yesterday, with gusty winds pretty much occurring in most cells./07/ && .PRELIMINARY POINT TEMPS/POPS...

An Easterly flow aloft will persist across the Four State Region with embedded disturbances expected to combine with available moisture and daytime heating resulting in destabilization, The result will be scattered showers and thunderstorms during the afternoon and evening. A few of the thunderstorms will become strong with gusty winds to 25-35 MPH, locally heavy rainfall with amounts to near one quarter to one half inch, and deadly lightning. Any hail that falls will be small. An isolated severe storm could form with winds to near 60 MPH but that threat is very small. In addition, afternoon temperatures will climb into the middle and upper 90s and when combined with the relative humidity can produce heat indices from 100-108 degrees. If working or venturing outside While outside, remember to take frequent breaks in the shade, wear light weight clothing and drink plenty of water. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... Rain chances to continue through next week, as a series of tropical waves progressing across the Gulf Coast States and embedded disturbances within the Easterly flow aloft will aid in the development of scattered showers and thunderstorms. A weak cold front moving in Saturday will serve as an additional focus for precipitation. Isolated strong to severe storms will be possible, with damaging winds and brief heavy rainfall the main threats. .SPOTTER INFORMATION STATEMENT... Activation of emergency managers, amateur radio operators, and storm spotters, is not expected through tonight. 06
