The episode as NWS SHV wrote it up.
Warm and moist air began to return north across the Ark-La-Tex during the daytime hours on March 24th, ahead of an upper level shortwave trough that traversed east across Southern Oklahoma and North Texas. This resulted in scattered showers and thunderstorms developing during the evening over Southeast Oklahoma and portions of North Texas, where better instability developed earlier in the day in response to daytime heating. Despite the marginal instability near the surface, ample shear and forcing were noted aloft ahead of this approaching disturbance and associated cold front, where several supercell thunderstorms developed over these areas during the evening. Additional scattered severe thunderstorms spread east southeast into Northeast Texas and Southern McCurtain County Oklahoma during the late evening hours. Large hail reports were received across portions of these areas, before the storms organized into a cluster and surged southeast across portions of East Texas and Northwest Louisiana during the early morning hours on the 25th. Damaging winds became prevalent along this line of storms, although occasional reports of large hail were also received, before the storms weakened after 330 am once instability diminished even further.
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 Mar 24, 11:15 PM CST, 2 hours 54 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Shreveport LA 1215 AM CDT Mon Mar 25 2019 .UPDATE... After coordinating with SPC and WFO FWD, have elected to extend SVR Watch #33 for several more counties in E TX until 09Z, while also dropping the watch for McCurtain County OK and the Nrn counties in SW AR, as the severe threat (while not zero), is considerably lower than farther S. However, a marginal severe threat remains across E TX where MLCapes of up to 1000 J/kg remain, although the short term progs suggest that instability will continue to gradually diminish overnight as the parent shortwave over Srn OK/N TX shifts E into Srn AR/N LA late, where the more stable air remains. Large hail will remain the primary threat, with damaging winds a secondary threat. Did not make any other changes to the ongoing forecast. 15 && .SHORT TERM.../Tonight/ The sct convection that did affect portions of McCurtain County OK earlier this evening have diminished/remained just N of this area and the adjacent counties in SW AR, as the convection has outran the greater axis of instability along the cold front, which extends from near FSM, to just S of MLC, AQR, SW to the Nrn and Wrn sections of the DFW Metroplex, to near SEP. However, additional sct convection has recently redeveloped near and just ahead of the front over portions of N TX, in the area of better instability where MLCapes near or slightly better than 1000 J/kg exist ahead of a shortwave trough noted over Srn OK and N TX. The short term progs have done a poor job with the handling of the ongoing convection, with the latest 00Z NAM much drier/less bullish with convection development through the remainder of the evening (especially near and N of DFW), but does suggest convection building ESE into more of E TX/extreme Nrn LA after 06Z. The latest run of the HRRR has initialized too far E with the ongoing convection and also does not take into account the convection N of DFW, but does suggest clusters of convection which should track SE across E TX into N LA overnight. Although some instability will persist overnight with additional low level moistening, the short term progs suggest that overall CAPE will continue to slowly diminish overnight, but with 500-800+ J/kg remaining over portions of E TX before the shortwave shifts E into slightly more stable air farther E into Scntrl AR/Ncntrl LA. Although an isolated severe threat may persist beyond the 05Z SVR Watch #33 expiration, did remove SVR mention after midnight, and did lower pops to likely across much of E TX/SW AR/N LA. But in the meantime, did add Smith and Gregg Counties in E TX to the existing SVR Watch #33 to account for extrapolation of the isolated severe warned supercell now entering Western Wood County. Also made very minor adjustments to the min temp forecast, with this convection diminishing from NW to SE late as H850-700 winds veer more WNW late. Zone update already out...grids will be available shortly. 15 && .PREV DISCUSSION... /issued 750 PM CDT Sun Mar 24 2019/ AVIATION... For the ArkLaTex terminals.

The threat of strong to severe thunderstorms will increase later this evening and overnight through early Monday morning as a cold front advances across the region. The highest risk area for severe weather will be north of a line from near Tyler, Texas eastward to Shreveport and Farmerville, Louisiana. The primary threats will be damaging wind gusts and large hail possibly up to golf ball size. Although the overall tornado risk is low, an isolated tornado or two cannot be completely ruled out. .DAYS TWO THROUGH SEVEN...Monday through Saturday... A couple of severe storms will still be possible through sunrise Monday morning, but the overall risk for severe weather should be diminishing. Damaging winds and large hail will be the primary threats. Thunderstorms will likely persist along and south of Interstate 20 until a cold front completely exits the area Monday afternoon. Scattered thunderstorms will return by late Thursday through Saturday as a series of upper level disturbances move across the region. Thunderstorm chances will be much higher, including the potential for more severe weather, as the front moves across the Four State Region during the day on Saturday. .SPOTTER INFORMATION STATEMENT... Spotter activation may be necessary tonight through early Monday morning.
