A strong upper level trough shifted east across Northern New Mexico into West Texas during the daytime hours of April 26th, which enhanced surface low development along the dryline in West Texas. Meanwhile, a warm front extended east from this surface low across much of North Texas, bisecting East Texas generally along the Interstate 20 corridor into Northwest and North-central Louisiana.

The episode as NWS SHV wrote it up.
A strong upper level trough shifted east across Northern New Mexico into West Texas during the daytime hours of April 26th, which enhanced surface low development along the dryline in West Texas. Meanwhile, a warm front extended east from this surface low across much of North Texas, bisecting East Texas generally along the Interstate 20 corridor into Northwest and North-central Louisiana. Showers and thunderstorms along and north of this warm front persisted through the day, given a series of upper level disturbances that ejected northeast ahead of the low atop the front, which kept the warmest temperatures and instability south of the front over Lower East Texas south of I-20 into West-central Louisiana. Large scale forcing increased during the afternoon south of the front and ahead of the eastward advancing dryline, with scattered to numerous showers and thunderstorms developing across the warm sector from the mid-afternoon through the evening hours. Some of these storms were severe, with multiple reports of large hail observed across Sabine Parish before diminishing after midnight.
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 Apr 26, 2:44 PM CST, 3 hours 11 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 344 PM CDT Wed Apr 26 2023 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Thursday Night) Issued at 344 PM CDT Wed Apr 26 2023 As expected, the morning/early afternoon convection has convectively reinforced the cool/stable air mass across much of E TX/Cntrl LA this afternoon, although the air mass has begun to modify some as the warm front has begun to lift N into portions of Deep E and the Wrn sections of E TX. This is evident in the lower to mid 60s isodrosotherms having recently advected back N into these areas, as well as some scattering of the cu field noted on the visible satellite imagery. However, time is running out on the advancement of the warm sector N across E TX/N LA, as elevated convection has become numerous and spread E into NE TX along and N of I-20, which should help to again convective reinforce the front from mixing much farther N during the evening. An isolated severe threat currently exists across the I-20 corridor of E TX, as bulk shear near 50kts and 2-6km lapse rates remain steep atop the warm front that is orientated farther S. However, believe that the main focus for severe convection will occur this evening through a portion of the overnight hours as convection continues to deepen ahead of a sfc low between ABI and COM, which will shift E along a W to E sfc bndry convectively reinforced to near and just S of the I-20 corridor from the DFW Metroplex into E TX/NW LA. This will occur once large scale ascent increases along these sfc features ahead of the closed low over the TX Panhandle, which will eject NE into Wrn OK during the evening. The HRRR remains consistent with earlier runs (and in better agreement than the other CAMs) with the convection entering the Wrn sections of E TX by the early to mid evening hours, with the moderate SBCapes expected to spread a bit farther N into E TX by that time. Thus, the convection should begin to intensify as it approaches Lower E TX, as it transitions potentially into a SE propagating MCS across Deep E TX/WCntrl LA during the late evening through a portion of the overnight hours. Have trimmed back the severe wording to these areas tonight, but also expanded on the heavy rain mention as consensus amongst the short term progs suggest that widespread rainfall amounts of 2-3+ inches is possible across much of E TX/Srn AR into portions of N LA. The storm intensities should gradually diminish overnight as the instability wanes, and a potential convective cold pool shifts ESE across the region in wake of the convection. The convection remains progged to diminish after daybreak Thursday across Cntrl LA, although the opening low will remain conducive for additional isolated to scattered convection development during the day over the region although this should diminish from W to E as drier air begins to entrain ENE beneath the opening trough. Did taper back max temps slightly Thursday afternoon given the extent of wrap- around cloud cover which looks to linger through a better part of the day, before drier air begins to mix ESE into the region late in the day with the passage of a weak cold front. A return to below normal temps is expected as the cigs scatter out Thursday night, with cool conditions returning through the overnight period. 15 && .LONG TERM... (Thursday night through next Tuesday) Issued at 344 PM CDT Wed Apr 26 2023 Friday morning will see the quiet conditions in the wake of Thursday's showers and storms continue for a brief window of time. The break in the rainfall looks to be short-lived, however, as the unsettled pattern which brings our mid-week storms will continue late into the week. Upper level flow around a broad area of troughing reaching from the Rockies in the west to the Appalachians in the east will sweep Thursday's trough away to the north and east, with another shortwave quickly on the way, pushing south along the Front Range and into north Texas, with a closed low potentially cutting off by late Saturday. This feature will provide the forcing necessary for another round of showers and possible storms to begin as soon as Friday afternoon north and west, expanding areawide overnight and remaining with the ArkLaTex through the day Saturday before finally clearing out overnight into Sunday as the closed low opens back into a shortwave and is absorbed by the larger area of troughing still situated over the Great Lakes region early next week. Temperatures will be fairly variable through the long term period, with a slight rebound into the upper 70s to low 80s Friday before Saturday's rainfall keeps highs in the upper 60s to low 70s. Sunday will see a return to more seasonable temperatures in the mid to upper 70s, with quieter, drier conditions and a slight warming trend to follow into early next week. /26/ && .AVIATION... (18Z TAFS) Issued at 107 PM CDT Wed Apr 26 2023 VFR conditions will continue across N LA/SW AR through the remainder of the afternoon, although MVFR cigs have developed across portions of E TX, in wake of the rains that fell earlier this morning. However, some cig deterioration will continue across E TX this afternoon as areas of convection continues to develop/spread NE generally along/N of the I-20 corridor into SE OK/SW AR. Have tempoed thunder in for TYR/GGG through the afternoon, with the expectation that the convection will backbuild/develop farther SSW into a more humid/unstable air mass S of a warm front that is slowly lifting N across Cntrl and ECntrl TX. The convection will increase into a more organized line as surge E across the region this evening/overnight, affecting LFK/SHV/TXK by late evening to just after 06Z, and ELD/MLU during the overnight hours, producing IFR/low MVFR cigs and reduced vsbys. Believe that this MCS will scour out the low cigs with its passage, with the potential for VFR conditions temporarily returning to the area until just after daybreak Thursday, at which point IFR cigs will redevelop. ESE winds 8-12kts with occasional higher gusts will continue this afternoon through much of the overnight hours. /15/ && .PRELIMINARY POINT TEMPS/POPS...
