The radar
The Ft Polk radar (KPOE), 103 km from the middle of the area, began a volume at 13:50 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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.
The nearest sounding before it
Fort Worth, TX (KFWD), launched 12:00Z, 1.9 hours before the alert went out and 352 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area Forecast Discussion National Weather Service Shreveport LA 624 AM CDT Sat May 23 2026 ...New AVIATION... .KEY MESSAGES... Issued at 135 AM CDT Sat May 23 2026 - Rain chances will continue over the Holiday Weekend with a Flood Watch south of I-20. - Daily rain chances will continue into next week, as a series of upper troughs move into the Region. - An elevated flood risk will remain during this wet period. Also, an isolated strong to severe thunderstorm can't be completely ruled out. . && .DISCUSSION... Issued at 135 AM CDT Sat May 23 2026 The warm front and associated sfc low that brought us rain on Thursday has moved north of the region. However, isolated to scattered thunderstorms developed yesterday evening across East Texas and North Louisiana along a convergence zone near the I-20 corridor. Some of those storms were strong enough to prompt severe thunderstorm warnings, as well as flash flood warnings due to their slow movement. That convection has diminished, but additional isolated showers and thunderstorms continue to develop at this hour across North Louisiana from remnant outflow boundaries from the earlier convection. Short-term progs continue this through the overnight period, before a complex of storms move into our area this morning in association with a strong short- wave disturbance moving along the established southwest flow upper pattern in place. Models are bringing the complex across our East Texas zones along and north of I-20 around daybreak. But, additional convection is expected during the late morning and afternoon hours as the short-wave trough moves into the region. Locally heavy rainfall and localized flooding will be possible with these storms, especially since we have saturated soils in place from recent rainfall. A Flood Watch is already in effect for most of our East Texas and Louisiana zones south of I-20, but I wouldn't be surprised if we need to extend it northward, as those areas have received decent rainfall over the past few days. From Sunday through all of next week, a couple of upper-level troughs will move into the Southern Plains, resulting in daily multiple rounds of showers and thunderstorms. The current Flood Watch will remain in effect through at least Monday evening, but could be extended through next week, as the elevated flood risk is likely to remain. The threat for organize severe weather will still remain low, but an isolated strong to severe thunderstorm can't be ruled out during this period. /20/ && .DISCUSSION...

(12Z TAFS) Issued at 621 AM CDT Sat May 23 2026 For the 23/12z TAF update...A strong line of thunderstorms is currently moving into our western zones of East Texas. The worst of it is through KTYR and is currently moving through KGGG. Expecting this line to impact all of our terminals throughout the morning hours from west to east. Additional activity will be possible throughout this TAF period. Gusty winds and hail will be possible under these storms as they pass through. A mixture of all flight categories can be expected over the next 24 hours with lower ceilings and lower visibility at times with thunderstorms. /33/ && .SPOTTER INFORMATION STATEMENT... Issued at 135 AM CDT Sat May 23 2026 Although spotter activation is not expected over the next 24 hours, moderate to heavy rainfall could lead to flash flooding.
