The episode as NWS SHV wrote it up.
A longwave trough dug south into the Southern Plains during the daytime hours of October 20th, with southerly winds increasing ahead of the trough helping to return low level moisture north from the Gulf of Mexico. Above normal temperatures were seen across much of the region as readings climbed into the mid 80s to near 90 degrees, which enhanced instability during the late afternoon through the evening hours across much of the Ark-La-Tex area. Wind shear increased during the evening, with an isolated supercell thunderstorm developing over Central Cherokee County Texas, which tracked northeast across Central Rusk, Western and Northern Panola Counties, and into the Shreveport/Bossier City areas of Northwest Louisiana before weakening. This supercell produced a tornado across Western Panola County Texas, with numerous reports of damaging winds which downed trees and power lines, as well as hail before diminishing over Northwest Louisiana. Additional strong to severe thunderstorms developed during the late evening through the early morning hours on October 21st across Northeast Texas, Southeast Oklahoma, Southwest Arkansas, and North Louisiana ahead of this trough and associated strong cold front, as wind shear increased within a still unstable environment. These storms produced numerous reports of damaging winds across these areas, with even another isolated tornado touching down in Central Cass County before diminishing shortly after daybreak with the departure of this system.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Oct 20, 3:06 PM CST, 2 hours 32 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 406 PM CDT Sun Oct 20 2019 .SHORT TERM.../Tonight through Monday Night/ Despite an abundance of low clouds and patchy fog this morning, temperatures have climbed well into the 80s this afternoon. Some areas along and south of I-20 have even managed the upper 80s for highs as a warm front has shifted north today. In addition, dew points have also surged into the lower 70s across much of these same areas. This is all occurring ahead of a cold front which is primed to move into our NW zones around midnight and quickly shift SE across the region overnight through Monday morning, setting the stage for a potential severe weather event across our entire four-state region. Although low-level instability may initially decrease slightly after sunset, expect it to increase once again with the approaching cold front as MUCAPE values spike toward the 2000-2500 J/kg range overnight and perhaps a bit higher in some locations. Add in the increasing low-level jet in the range of 50-60 kts and veering wind profiles with increasing wind shear, a very robust line of convection will develop and spread SE toward the I-30 corridor where an Enhanced Risk of severe weather is noted in the SPC Day 1 Outlook. This line will continue on to the SE across the remainder of the region with a primary damaging wind threat coupled with the lower threats of large hail and isolated tornadoes, which would likely be embedded within the evolving QLCS. Rainfall amounts will average near an inch across the region with isolated higher amounts possible over the next 24 hours. The line of convection should exit the region by early to mid afternoon on Monday with cooler and drier spilling south across the region. Highs on Monday afternoon will range through the 70s while overnight lows will fall into the 40s to near 50 degrees in wake of the cold front on Monday night under clear skies and light NW winds. /19/ .LONG TERM.../Tuesday through Sunday Night/ A departing trough of low pressure extending from the Great Lakes into the Lower Miss Valley on Tuesday will result in milder temperatures and drier conditions through at least Wednesday. By Thursday, the westerlies will remain rather active as yet another trough of low pressure moves out of the Intermountain West and into the Great Plains. Low level moisture should increase quickly Wed Night into Thu with perhaps some diurnally driven isolated to scattered convection possible across our western half on Thursday and then chance pops areawide Thu Night into Friday. There continues to be considerable discrepancies concerning how this late week trough will evolve with the ECMWF/Canadian solutions suggesting the base of the trough will cut itself off from the westerlies on Friday in the lee of the Southern Rockies while the more progressive GFS suggests the trough will be much more open and quickly brings an end to the rainfall across our area on Friday. The differing solutions remain dug-in in regards to the above features so tried to blend the varying solutions which would result in rain chances lingering at least into the first half of Saturday. Regardless, look for much cooler conditions with a frontal passage sometime late Thursday or Friday with a cool upcoming and possible wet first half of next weekend. 13 && .PREV DISCUSSION... /issued 1257 PM CDT Sun Oct 20 2019/ AVIATION... For the 20/18Z TAF period, flight conditions continue to improve as lower cigs lift/clear with VFR now at our East Texas terminals and SHV while MVFR/IFR conditions linger at TXK/ELD/MLU into the early afternoon. However, these sites are expected to go VFR in the next hour or two as a warm front continues to lift northeast. Convection will be very isolated through the remainder of today but begin to increase later tonight ahead of a cold front. Strong to possibly severe convection will follow overnight through early Monday along the front with a solid line of thunderstorms expected to develop with strong and gusty winds spreading southeast across all sites through Monday morning. In the meantime, winds will be generally around 10 kts or less from the S/SW ahead of the front and then quickly veer N/NW with fropa as speeds increase to near 15-20 kts with higher gusts, especially invof of the front/along the line of convection. Cigs/vsbys will also deteriorate quickly as this convection advances across the region on Monday morning, likely prevailing MVFR/IFR through the end of the TAF period. /19/ && .PRELIMINARY POINT TEMPS/POPS...
