The episode as NWS SHV wrote it up.
A large upper trough extended from the Upper Midwest south into East Texas during the afternoon and evening of September 6th. At the surface, a moist and moderately unstable air mass was in place, with temperatures climbing into the lower 90s during the afternoon. With large scale forcing increasing ahead of the upper trough, isolated showers and thunderstorms developed over portions of Northwest Louisiana during the afternoon and evening, with one storm briefly becoming severe over Northern Bossier Parish, where damaging winds downed trees and power lines near Plain Dealing.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Sep 6, 7:34 PM CST, 1 hour 9 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 834 PM CDT Tue Sep 6 2022 ...New UPDATE... .UPDATE... Issued at 827 PM CDT Tue Sep 6 2022 An area of enhanced CAPE values from McCurtain County southeast to near Shreveport will continue to sustain convection through the late evening hours across these areas. For this forecast update, went ahead and increased pops through midnight areawide. Beyond midnight through at least daybreak convection should be minimal before reigniting on Wednesday as upper-trough and surface boundary shift southward. Update already out. /05/ && .SHORT TERM... (This evening through Wednesday Night) Issued at 205 PM CDT Tue Sep 6 2022 The troughing upper level low responsible for today's pattern across the ArkLaTex will continue steering the forecast through the course of this short term period. With a pronounced large high over the Intermountain West, troughing around a closed low over the upper Midwest will deepen southwestward into the Four State Region, broadening and sliding gradually to the southeast into the day Wednesday, becoming reoriented around a new closed low over the Gulf Coast of LA/MS/AL. In terms of specific weather impacts on the ArkLaTex, this afternoon's thunderstorm activity will begin to taper off into the evening hours. The night does not look to remain entirely quiet, however, as a burst of upper level energy looks to ride down the forward side of the ridge overnight, serving to kick up areas of redeveloping convection along and north of the I-30 corridor in the pre-sunrise hours, spreading southeast by daybreak. This area of activity will overspread the I-20 corridor into the morning, with areas along and south of I-20 remaining active through the day Wednesday, with convection tapering off to the south after 00Z Thursday, with a quiet night to follow. Temperatures will continue to reflect recent trends, falling into the low 70s overnight tonight, climbing back into the upper 80s to lower 90s Wednesday, with a few upper 60s creeping into our northern zones Thursday morning, with lower 70s elsewhere. /26/ && .LONG TERM... (Thursday through next Monday) Issued at 205 PM CDT Tue Sep 6 2022 As we begin the long term portion of the forecast, the upper level trough currently parked across the heart of the Four State Region will have migrated south and east, taking up residence across SE LA into S MS and N GA. This feature should be far enough south to become cutoff from the longwave trough which will exit the New England Seaboard late Thu into Fri. In the wake of the longwave trough will be an expansive ridge extending from the Bahamas northward into New England and that will be a blocking feature for the upper trough across our region. In fact, the trough is forecast to retrograde back to the west slightly, into our region and this will result in an increase in convective coverage on Saturday, more so across our eastern half. The upstream kicker, another longwave trough entering the Great Plains Sat into Sat Night will serve to lift our trough out of the Lower Miss Valley. The kicker trough will have a stout cold front associated with it that will push through our region during the day Sunday into Sunday Night, bringing and end to our rain chances and ushering in some cooler, drier air for the beginning of next week. In fact, some progs are hinting at low temperatures Monday and Tuesday in the lower 50s across our far northern zones with lows in the middle 60s elsewhere. Will stay conservative this far out and forecast lows ranging through the 60s areawide early next week but a hint of fall is not far away. 13 && .AVIATION... (00Z TAFS) Issued at 630 PM CDT Tue Sep 6 2022 Persistent upper-level trough to gradually work south allowing for increased chances for showers and thunderstorms across the region on Wednesday, mainly across the I-20 corridor terminals and southward. Otherwise, could see MVFR/IFR ceilings by daybreak, improving to VFR outside of convection after mid-morning through the end of the terminal forecast period 08/00Z. Otherwise light and variable winds overnight to become northeast at 5 knots on Wednesday. /05/ && .PRELIMINARY POINT TEMPS/POPS...

Isolated to scattered showers and thunderstorms tied to daytime heating will erupt across portions of the Four State Region this afternoon. The strongest storms will have the capability of producing small hail and strong wind gusts along with locally heavy rainfall. These heavy downpours could result in minor flooding of low lying and poor drainage areas. While we should see storm coverage and intensity diminish during the late evening hours tonight, there could be a redevelopment of storms late tonight towards sunrise near and northwest of the Interstate 30 Corridor of Northeast Texas, Southeast Oklahoma and Southwest Arkansas. These storms, if they develop, could be heavy rainfall producers. .DAYS TWO THROUGH SEVEN...Wednesday through Monday. Isolated to scattered, mainly afternoon and evening showers and thunderstorms are expected each day through this weekend. The best coverage will likely come on Wednesday as a cold front shifts south across the region. Once again, gusty winds and dangerous lightning may also accompany any heavy downpours throughout the week and into this weekend. .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected at this time. 13
