The episode as NWS SHV wrote it up.
A hot, humid, and unstable air mass was in place across much of the Ark-La-Tex region on August 25th, which sat on the western periphery of an upper level ridge of high pressure that was anchored over the Tennessee Valley. An upper level disturbance rounded this ridge to the northwest over the region during the afternoon, contributing to the development of scattered to numerous showers and thunderstorms over much of Southwest Arkansas, North Louisiana, and portions of East Texas. These storms continued to redevelop along outflow boundaries as they built westward during the afternoon and evening, but moved very little resulting in locally heavy rain falling over the same areas over an extended period of time. Given the already saturated grounds from an abnormally wet August, these heavy rains quickly ran off, resulting in areas of flash flooding across portions of extreme Northwest Louisiana and Southwest Arkansas. Widespread rainfall amounts of one to three inches, with isolated higher amounts near four inches, fell over much of North Louisiana, Southwest Arkansas, and portions of East Texas.
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 Aug 25, 3:09 PM CST, 1 hour 51 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 409 PM CDT THU AUG 25 2016 .DISCUSSION... Latest water vapor loops clearly show a rich plume of tropical moisture streaming northwest into the area from the Gulf of Mexico and around the western periphery of an upper ridge centered over the Southeast U.S. An upper wave moving west through the Gulf has tapped into this moisture and aided in development quite a bit of convection over Southern Arkansas, much of Louisiana, and portions of East Texas. Steering flow aloft is relatively weak. PW values above 2 inches combined with training cells could lead to some localized flooding with this activity. Convection is mainly diurnally driven and is expected to greatly diminish after sunset. Large scale ascent from this Gulf wave will remain over the area and will allow at least a slight chance for showers and thunderstorms tonight before coverage and intensity increase during the daytime hours of Friday. A severe weather threat is not anticipated, but gusty winds and a localized flooding threat are possible with the stronger storms. By Saturday, the Gulf wave will be just off the Texas coast. A surface low will develop with the wave, which will shift most of the deepest moisture south and west of the CWA. Thus, chances for diurnal convection will gradually decrease through the weekend, but a chance for scattered thunderstorms will remain possible during the daytime hours especially southwest of a line from Broken Bow, OK, to Jena, LA. The low will move farther inland into Texas by the beginning of next week leaving most of the CWA on the dry side. The best rain chances Monday through Wednesday will generally be limited to the far southern zones in Deep East Texas eastward into Central Louisiana. As rain chances decrease, temperatures will gradually climb back into the mid 90s. Heat indices may rise above 100 degrees F and possibly approach advisory criteria. Concerning the tropics...the tropical wave in the Caribbean Sea continues to be relatively unorganized. Considerable uncertainty still exists with this system. However, the latest operational models and ensembles are currently keeping this potential tropical system well east of our CWA. /09/ && .PRELIMINARY POINT TEMPS/POPS...

4 flash flood. Local standard time, as filed.
At least one motorist required a high water rescue on Youree Drive due to flash flooding. The Shreveport Fire Department blocked off Youree Drive near Arthur Ave. due to flooding. Many of the side streets off of Youree Drive were flooded with one to two feet of water.
A few cars were stalled out in high water near Shreveport-Barksdale Highway and Knight Street. A truck became submerged in a ditch along Shreveport-Barksdale Highway. Fortunately, the two occupants in the vehicle were able to escape safely.
