The episode as NWS SHV wrote it up.
A weak upper level trough of low pressure remained stationary from Central Texas northeast across Eastern Oklahoma, Northwest Arkansas, and into Southern Missouri on August 16th. This disturbance interacted with a lingering surface boundary over Southeast Oklahoma and Southwest Arkansas, and a very moist and unstable air mass in place to result in scattered to numerous showers and thunderstorms that developed over much of Southwest Arkansas. These thunderstorms produced locally heavy rainfall and moved very little over portions of Southwest Arkansas, resulting in rainfall totals of three to in excess of four inches over Northern Lafayette and Columbia Counties, as well as Southern Nevada County. This resulted in numerous roads becoming flooded across northern Lafayette County.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Aug 16, 9:49 AM CST, 41 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 1049 AM CDT TUE AUG 16 2016 .DISCUSSION... No forecast update needed at this time... && .PREV DISCUSSION... /issued 715 AM CDT TUE AUG 16 2016/ AVIATION... For the 16/12Z TAFS...Mostly MVFR conditions with occasional IFR cigs/vsbys are occurring in areas of light to moderate showers. Further expansion of showers and some embedded thunderstorms will be common as we go through today. This will keep MVFR conditions prevailing at most terminals throughout the day with IFR periods during heavier showers/storms. Convection should trend downward after 17/03Z with more spotty coverage through the latter half of the period. Winds will be mostly light and variable with an east to southeast component for much of the period. /19/ PREV DISCUSSION... /issued 244 AM CDT TUE AUG 16 2016/ DISCUSSION... Scattered to numerous showers across the region once again early this morning with our wet weather pattern expected to continue for the foreseeable future. This stagnant weather pattern due in part to strong forcing aloft downstream of a stubborn trough of low pressure across Central Texas into Eastern Oklahoma and Southern Missouri. Our surface trough which helped to focus some heavier rainfall totals on Monday has shifted just north and west of our region early this morning but looking aloft at the 850mb level...there remains a strong thetae gradient across the northwest half of the region. This will combine with the high pwat airmass in place to produce scattered to numerous showers and a few thunderstorms once again today. HRRR model picking up on another strong seabreeze signal once again for this afternoon coming northward from S LA and SE TX which should result in good precip coverage just about everywhere today. As was the case on Monday...there will be pockets of heavier rainfall given the tropical nature to the airmass but just where those pockets will materialize is very difficult to determine. This same pattern will stick with us through at least Thursday but there are subtle indications that a weak ridge of high pressure across the Southeast U.S. will try to retrograde westward into our region which will help to shift the focus for higher coverage of precip to our northern most zones by the end of the work week into next weekend. Having said that...even across our southern half where pops will not be as high as our northern zones...precip will be more tied to daytime heating which given the airmass should result in scattered convection. Another longwave trough enters the Plains late next weekend into early next week which could help to ramp up precip chances once again but until then...temperatures will remain some 15 to 20 degrees below normal the next few days given the rain probabilities with a slow warning trend as we move into the end of the week into next weekend ahead of the trough.

PERIODS OF SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE TODAY THROUGH TONIGHT DUE TO A VERY MOIST ATMOSPHERE IN PLACE AND AN UPPER LEVEL DISTURBANCE REMAINING RATHER STAGNANT ACROSS THE REGION. THE HIGH MOISTURE CONTENT OF THE ATMOSPHERE MEANS THAT THERE WILL BE PERIODS OF LOCALLY HEAVY DOWNPOURS...SOME OF WHICH COULD PRODUCE EXCESSIVE HEAVY AMOUNTS OF RAIN. THIS COULD RESULT IN SOME LOW AREA FLOODING...ESPECIALLY IN FLOOD PRONE AND POOR DRAINAGE AREAS.
