The episode as NWS SHV wrote it up.
A weak shortwave trough traversed southeast across Southern Arkansas and Northcentral Louisiana during the afternoon of September 16th, as temperatures climbed into the mid and upper 90s. As a result, moderate to strong instability developed given the existing low level moisture in place, with increased large scale ascent contributing to the development of scattered strong to severe thunderstorms across portions of Southern Arkansas and Northcentral Louisiana during the late afternoon and early evening hours. These storms produced instances of damaging winds which downed trees and power lines, as well as isolated instances of large hail across portions of Ouachita, Union, and Lincoln Parishes before diminishing during the evening.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Sep 16, 12:21 PM CST, 4 hours 4 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Shreveport LA Issued by National Weather Service Fort Worth TX 121 PM CDT Tue Sep 16 2025 ...New DISCUSSION AND AVIATION... .KEY MESSAGES... Issued at 120 PM CDT Tue Sep 16 2025 - Above-normal temperatures with isolated to scattered showers and thunderstorms are forecast the next few days. - Higher rain chances with near seasonal temperatures return by the end of the week and continue through the weekend. Rain chances are highest for areas in and northwest of the ArkLaTex. && .DISCUSSION... Issued at 120 PM CDT Tue Sep 16 2025 While the synoptic pattern is relatively atypical for this time of the year, the sensible weather is very typical of the summer. Highs should peak in the mid 90s with heat index values in the upper 90s. Diurinally-driven showers and thunderstorms (less than 20% coverage) are forecast to develop this afternoon, with even less coverage in East Texas. A weak shortwave trough should move across the southeastern half of the area tonight and develop a few showers and perhaps an isolated thunderstorm or two. Similar weather is forecast tomorrow, but with greater coverage of showers and thunderstorms in the afternoon due to slightly weaker mid- and upper-level subsidence. The pattern should become more active as we head into the end of the workweek and this weekend. The ridge responsible for the quiet weather recently will be replaced by more active northwest flow aloft, opening the door for transient shortwave troughs to move into the area. Rain chances will be highest for those within and northwest of the ArkLaTex (where the greatest forcing associated with each shortwave trough will be). While isolated showers and storms will be possible for the remainder of the forecast area each day, the lack of an organized source of ascent will keep the coverage on the low side. The combination of cloud cover and weaker subsidence will also allow for highs to return to near the seasonal normals, which will certainly be welcome. Most of the extended guidance indicates a relatively strong mid- and upper-level trough deepening over the Southeastern CONUS in the early-to-mid parts of next week. Cluster analysis of the ensemble members indicate a roughly 1 in 4 chance that the low starts as a cutoff low over West Texas. This pattern would favor higher rain chances (and lower temperatures) across the entire region early next week. The other 3/4ths of the guidance is drier and deepens the trough overhead and to our east. The 1/4 of ensemble members that favor a low developing to our west have much higher rain totals compared to the drier 3/4. These higher values are driving up the entire ensemble mean when it is compared to the 50th percentile (median) value. Due to the spread between the 50th percentile and mean value, advertising rain totals for next week's systems are far too unreliable. This is still 7-10 days out, so we have some time to start to hone in on a solution. && .AVIATION... (18Z TAFS) Issued at 120 PM CDT Tue Sep 16 2025 Shallow cumulus has developed across much of the area already. Most of the cumulus today should be innocuous, but expect about 20% coverage of showers and thunderstorms this afternoon. Since coverage is on the low-end, we did not include any tempo or on- station mention of precip in any of the TAFs. There is a 20-30% chance that a few showers linger through the evening across Louisiana and southeast Texas, but most of this should be away from our TAF sites. Northwest winds this afternoon will become light and generally variable (from 200-300) this evening and tonight. There should be greater coverage of showers and storms tomorrow, but mainly after 18Z. && .SPOTTER INFORMATION STATEMENT...
