The episode as NWS SHV wrote it up.
A weak cold front drifted south into Northeast Texas and Southwest Arkansas during the evening hours of November 3rd, ahead of a weak upper level disturbance that shifted southeast across the Middle Red River Basin of North Texas and Southern Oklahoma. Moderate instability developed along and ahead of the front due to an unusually warm and moist air mass in place, with near record temperatures observed on the 3rd. Despite the presence of a shallow low level moisture field in place, enough forcing aloft ahead of the upper level disturbance coupled with the moderate instability, resulted in the development of isolated to widely scattered showers and thunderstorms ahead of the front over portions of Northeast Texas, Southcentral Arkansas, and Northern Louisiana. One isolated severe thunderstorm developed over extreme Northeast Rusk County Texas, which moved into Northwest Panola County before weakening. This resulted in reports of large hail and gusty winds which downed a tree near Tatum.
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 Nov 3, 5:52 PM CST, 18 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 652 PM CDT Fri Nov 3 2017 .AVIATION... For the 04/00z TAFs, isolated convection will persist for the first several hours of the TAF period mainly east of a line from KDEQ to KGGG to KLFK along and ahead of a weak cold front. Rain chances should diminish from west to east by 04/06z as daytime heating wanes and an upper trough axis moves east of the region. Patchy fog and low stratus are expected during the overnight/early morning hours resulting in MVFR/IFR flight conditions. Ceilings will slowly improve after sunrise Saturday morning, but most TAF sites, with the possible exception of KMLU, should improve into the low end of VFR by 04/18z. CN && .PREV DISCUSSION... /issued 208 PM CDT Fri Nov 3 2017/ DISCUSSION... Cold front continues to make slow but steady progress south and east into our northwest zones this aftn. Cold front as of 18z was located near or just east of a TYR to DEQ line. Cu field in the warm sector, especially just along and ahead of the cold front is trying to show some definition on VIS Satellite but latest mesoanalysis shows that the capping inversion is trying to hang on. Expect another hour or two of heating should weaken the cap in order for some isolated to scattered thunderstorms to develop on or just ahead of the frontal boundary across portions of extreme Northeast Texas, Southwest Arkansas into extreme Northern and Northeast Louisiana. Latest meso analysis showing SBCAPE values are near 2500-3000 J/KG across SW AR into N LA. While instability remains sufficient for some strong to severe thunderstorms later this afternoon into this evening, depth of moisture continues to be unimpressive with moisture confined to only the lowest 5kft of the atmosphere. Having said low level lapse rates will approach 8 degrees across our extreme northeast zones later this aftn/evng so absolutely cannot rule out a few strong thunderstorms and/or an isolated severe thunderstorm in the 4-9pm window. Convection should quickly dissipate in coverage and intensity late this evening. The cold front will push a little further south and east this evening before stalling out and returning back to the north as a warm front Saturday morning. Have introduced the possibility of fog in the warm and cool sectors of the front after midnight and continuing through the mid morning hours for Saturday with some of this becoming dense fog in a few locations. In the wake of this disturbance tonight, upper flow becomes rather flat and uneventful across the Southern Plains/Lower Miss Valley. This will result in much above normal temperatures continuing not only during the day but at night as well. Overnight lows after tonight will range in the middle 60s to near 70 degrees through the weekend into early next week with daytime highs in the lower to middle 80s this weekend into early next week. These overnight temperatures will be some 15 to 20 degrees above normal for the first week of November with daytime highs some 10 to 15 degrees above normal. Our next weather maker in the form of a disturbance embedded in a progressive westerly flow pattern appears to begin influencing our region Wed into Thu of next week and with it will be our next good chances for rain. The trough will also put a dent in the near record heat we will see over the next 4 days but this airmass is of a Pacific origin with temperatures returning to near normal if we are lucky for the second week of November.

These storms are not expected to become strong or severe and should weaken in coverage and intensity during the evening hours. Otherwise, no hazardous weather is anticipated through tonight. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... Another much stronger cold front will approach and move across the Four State Region by the middle of next week with another chance of showers and thunderstorms. This is a Pacific air mass and very cold air will not accompany this front. No organized threat for hazardous weather is expected at this time. .SPOTTER INFORMATION STATEMENT... Activation of emergency management personnel...amateur radio operators and storm spotters will not be needed through the weekend.

With the aid of daytime heating, a weak disturbance aloft moving into the region from the west and an associated cold front, there will be the possibility for some strong thunderstorms later this afternoon into the evening hours across the region. While these storms are not expected to become widespread, an isolated strong to severe thunderstorm cannot be ruled out, especially across portions of South Central Arkansas into Northern Louisiana. Any strong to severe thunderstorm if they develop would produce hail and strong wind gusts. Otherwise, the convection is expected to weaken in coverage and intensity late tonight. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... Another much stronger cold front will approach and move across the Four State Region by the middle of next week with another chance of showers and thunderstorms. This is a Pacific air mass and very cold air will not accompany this front. No organized threat for hazardous weather is expected at this time. .SPOTTER INFORMATION STATEMENT... Activation of emergency management personnel, amateur radio operators and storm spotters should not be needed through tonight. However, while no widespread severe weather is anticipated late this afternoon through tonight across the region, isolated strong to severe thunderstorms cannot be ruled out. 13
