Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

13What forecasters said that day
The local office's own words before this tornado warning went out, 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 this tornado warning went out at May 16, 3:13 PM CDT, 31 minutes earlier.
Area forecast discussion, May 16, 3:13 PM CDT, 31 minutes before
Area Forecast Discussion National Weather Service Shreveport LA 313 PM CDT Sat May 16 2020 .SHORT TERM.../Tonight through Sunday Night/ Convection has increased significantly this afternoon as heating influences have helped destabilize the atmosphere with an upper trough pivoting eastward into the region, allowing for steeper lapse rates aloft and more upscale growth of these thunderstorms. Our biggest concern this afternoon is with some weakly rotating storms and possible brief spin-up tornadoes with a few tornado warnings having already been issued thus far. Favorable conditions will continue through the remainder of the afternoon and into the early evening hours as a sfc low continues to drift eastward into the region, providing for modest low-level shear with 0-1km shear values near 200 m2/s2. Aside from the tornado potential, we also continue to monitor rain rates across NE Texas and SE Oklahoma where the heaviest rainfall has occurred so far this afternoon. Training storms haven't really been an issue up to this point, but still cannot rule out some brief heavy rainfall that could produce isolated areas of localized flooding. However, it doesn't appear that a Flash Flood Watch is needed at the moment but this threat will continue to be closely monitored over the next several hours. Through tonight, look for convection to continue spreading farther north and east as the upper trough swings overhead along with the associated low pressure center aloft and at the sfc. Therefore, have maintained high PoPs areawide through the overnight period with temperatures gradually cooling back down into the 60s. Rain chances will remain quite high for much of the region on through Sunday before convection gradually begins to diminish from west to east late in the day through Sunday night. Temperatures will range from the upper 70s to near 80 degrees for highs on Sunday before cooling back into the 60s again overnight as clouds clear from the NW to SE. Cool NW winds will prevail through Sunday night and help push temperatures even cooler across our northern zones with mid to upper 50s expected by early Monday morning. /19/ .LONG TERM.../Monday through Saturday Night/ By the start of the upcoming work week, our current upper level trough will be well east of our region and will eventually be absorbed by a vigorous upper level trough that will become cut off from the westerlies as it moves southward from the Ohio Valley into the Tenn Valley by Tue with the trough moving very little into Thu. On the backside of this trough will be an expansive ridge of high pressure in the upper levels that will extend as far south as the Mexican Plateau and as far north as the Upper Plains into the Great Lakes. This trough will have a warming influence across our region with highs in the 80s through much of the upcoming week but a drying influence as well. Some medium range members are trying to suggest pops increasing again as we head into the late week and upcoming weekend and while that may very well be the case, will stay close to the NBM which is taking its cues from the drier ECMWF and CMC suggesting a stronger upper ridge in place across the Southern Plains/Lower Miss Valley through at least Sat of next week. 13 && .PREV DISCUSSION... /issued 119 PM CDT Sat May 16 2020/ AVIATION... For the 16/18Z TAF period, mostly MVFR cigs are currently observed at our area terminals this afternoon with this extensive low cloud cover expanding north and east ahead of an upper trough and closed low across East Texas. Expect showers and thunderstorms to become more numerous this afternoon and through this evening as the upper trough and the center of the low shift farther east into the area. Showers will continue through much of Sunday morning with embedded thunderstorms still possible as the trough moves directly overhead and winds begin to veer more W/NW as the sfc low shifts eastward. Wind speeds will vary through the period, generally ranging from 5-15 kts with some higher gusts near 20kts possible. Cigs will be slow to improve behind the trough and passing low with IFR/MVFR conditions likely prevailing through the remainder of the period. /19/ && .PRELIMINARY POINT TEMPS/POPS...
