The episode as NWS SHV wrote it up.
A weak stationary front extended north of the Interstate 20 corridor in Northeast Texas east into far Southern Arkansas during the afternoon hour of May 17th, which began to drift back north by late afternoon into the evening, as a southerly low level flow developed across the broad warm sector to the south, in response to tighter pressure gradient ahead of an upper level trough that traversed northeast from the Southern Plains into the Ozarks. Ample daytime heating atop a very moist air mass along and south of the front contributed to strong instability, with increased large scale forcing ahead of the trough and along the front resulting in scattered severe thunderstorms developing during the afternoon and evening across portions of Southern Arkansas, extreme Northeast Texas, and Southeast Oklahoma. Several reports of large hail and damaging winds were received from these storms, before they shifted northeast of the area into Western and Central Arkansas by late evening.

Area Forecast Discussion National Weather Service Shreveport LA 628 PM CDT Sat May 17 2025 ...New AVIATION... .SHORT TERM... (This evening through Sunday Night) Issued at 247 PM CDT Sat May 17 2025 After dodging severe weather yesterday, it doesn't appear we will have the same fortunes this go 'round. From a simple comparative standpoint, we are seeing far more breaks in the cloud cover this afternoon as compared to this time yesterday. Additionally, our 12Z sounding from this morning indicated a much weaker capping inversion than we were dealing with yesterday. Hence, yesterday's significant lack of convection across our region is not likely to repeat itself later this afternoon and evening. This thinking is reinforced by the fact that forcing aloft is expected to be much stronger this evening as a shortwave disturbance embedded in SW flow aloft is noted this afternoon over Central Texas. This has already resulted in several thunderstorms going severe SW of the DFW metro area. This trend is only expected to increase farther east toward the I-35 corridor as we go through the remainder of this afternoon, then eventually spreading into the I-30 and I-20 corridors across our region by early this evening. At the sfc, we continue to analyze a cold front just north of our region. South of the boundary, sfc-based CAPE has skyrocketed into the 4500-6000 J/kg range with modestly steep mid-level lapse rates as well. As strong to severe storms continue to evolve out to our west this afternoon, hi-res CAM guidance suggest this convection should eventually congeal into a bowing MCS or large wind-driven cluster of storms by early to mid evening as they enter our NW zones. This thinking was much of the impetus for SPC expanding the Day 1 Enhanced Risk across a larger swath of our northern CWA. In addition, large hail will be possible with any individual storms that develop later this evening and along with the potential MCS. Given the excessively high level of instability, very large hail over 2 inches in diameter is certainly plausible. As we approach midnight, the severe threat should gradually begin to diminish as the aforementioned shortwave pivots NE of the region. However, we may not lose convection entirely due to the sfc boundary easing farther south into our northernmost zones but don't anticipate this posing a severe threat beyond midnight into early Sunday morning. Unfortunately, the threat of additional severe weather will return late on Sunday into Sunday night once again across our the more NW parts of CWA. This will occur as another shortwave quickly ejects across Texas over the same general area as today's disturbance with the Middle Red River Valley directly in the crosshairs. Damaging winds and large hail will be the primary threats once again, but a few tornadoes cannot be ruled out. Similar to tonight, the severe threat will gradually diminish by late evening toward midnight as upper forcing exits to the NE. Temperatures throughout the remainder of the weekend will remain well above average due to the lack of frontal passage during this short-term period. /19/ && .LONG TERM... (Monday through next Friday) Issued at 247 PM CDT Sat May 17 2025 The active weather pattern will continue through early next week before we finally see a cold front advance across the region on Tuesday and Tuesday night. Ahead of this front, very warm and unstable air will continue to support strong to severe convection from Monday afternoon through Tuesday. Initially, the NW half of the region will be under the gun for severe storms by late Monday ahead of the approaching front with all modes of severe weather possible. Moving into Tuesday, the severe threat will shift to our SE half with fropa occurring early in the day across our NW zones. Shear and instability will continue to support all severe modes through late Tuesday before the threat finally exits the entire region by Tuesday night. The front will usher in a much more comfortable air mass with post-frontal temperatures running very near to slightly below seasonal averages through the remainder of next week. /19/ && .AVIATION... (00Z TAFS) Issued at 621 PM CDT Sat May 17 2025 Very little to no changes from the 18z TAF package to the 00z TAF period. Convective uncertainty continues given a lack of hi-res confidence from run to run. That being said, recent radar trends from the FWD airspace were enough to prevail SHRA at TYR, while also including a TEMPO period at both TYR and GGG for TSRA as a bowing complex south of DFW moves east. From there, much uncertainty continues as it will be highly dependent upon how the complex holds together or decays. To account for uncertainty, and to align with the hi-res solutions which have struggled detecting early convection, elected to include VCTS at many terminals after 00z to account for the potential. By the morning, and long after the complex has either dissipated or departed, low dense OVC will once again prevail across the local terminals below 3kft, becoming more SCT to BKN by the afternoon as high level cirrus returns aloft around FL200. Convective target for late in the TAF period looks to be closest to KTXK and as a result, mentioned VCTS close to 19/00z. KNAPP && .SPOTTER INFORMATION STATEMENT...
