A slow moving cold front across northwest Louisiana encountered a moderately unstable airmass and a moist airmass with the result being slow moving thunderstorms. These thunderstorms produced excessive heavy rainfall amounts, especially across Webster Parish.

The episode as NWS SHV wrote it up.
A slow moving cold front across northwest Louisiana encountered a moderately unstable airmass and a moist airmass with the result being slow moving thunderstorms. These thunderstorms produced excessive heavy rainfall amounts, especially across Webster Parish. Flash flooding was reported in the town of Minden, Louisiana.
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 Sep 10, 3:05 PM CST, 2 hours 29 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 405 PM CDT SAT SEP 10 2016 .DISCUSSION... Sct convection is just now beginning to fire over Union County AR SW into portions of extreme NW LA and adjacent E TX...along the weak cold front and line of agitated cu over these areas. The air mass ahead of the front has become moderately unstable...indicative of MLCapes of 2000-2500 j/kg. The latest run of the HRRR continues to suggest this convection continuing to expand through early evening across the warm sector as the front slowly slips SE into Ncntrl LA/lower Toledo Bend Country...before diminishing with the loss of heating/instability. Have raised pops to low chance this evening for the aforementioned areas...reducing pops to slight chance after 06Z for the Srn/Ern zones as the front sags S. The short term progs are now depicting even cooler temps than earlier runs tonight through Sunday night...with temps falling into the upper 50s late over McCurtain County OK and adjacent sections of Wrn AR. Can/t argue with this given that current dewpoints have fallen off into the upper 40s to near 50 across Ern OK...with the clearing line just NW of these areas attm. The progs are also suggesting the front pushing farther S than earlier indicated...into Srn LA to the SE TX coast Sunday...although the drier air will lag the front a ways to the N over Cntrl LA/lower Toledo Bend Country. In addition...upper ridging will begin to build E across the Srn Plains Sunday before expanding across the Ark-La-Tex Sunday night and Monday. Thus...any isolated convection Sunday should be concentrated farther S mainly across the Srn counties and parishes...and have trimmed pops down to slight chance for these areas...with any isolated convection diminishing by sunset. Sfc ridging will persist over the region Sunday night resulting in cooler temps filtering over more of the region. This will be short-lived though as the air mass will begin to gradually modify Monday as the sfc bndry to our S will begin to wash out...and bndry lyr moisture begins to return NNW. Upper ridging will persist over the region Tuesday and Wednesday...with any isolated convection confined mainly across the Srn zones where the ridge will be weakest. The ridge should begin to drift E of the MS Valley by Thursday...with shortwave troughing developing across the Srn Plains ahead of the next Cntrl Plains trough/attendent SW flow developing. Thus...convection should become more sct over E TX/SE OK Thursday before expanding areawide by week/s end. Have adjusted pops to mid-chance to match for now...with needed rain and slightly cooler temps possible as much of the region is going on in excess of 2 weeks with little to no rain and abnormally warm temps. Prelims to follow below... 15 && .PREV DISCUSSION... /issued 123 PM CDT SAT SEP 10 2016/ AVIATION... For the ArkLaTex, MVFR deck encroaching from NW in the wake of TSTM outflow overnight has the cold front filtering down under this deck from KTYR to KTXK. Pretty good cu field and heating going for much of area with tempo groups for convection timed with rapid refresh as the boundary slides SE this cycle. Any real chance for a brief shower will come to end perhaps with sunset as Northerly winds filter down overnight. Aloft KSHV VAD is showing W/NW flow 5-15KTS for climb out. All winds bcmg NE for Sun. /24/ && .PRELIMINARY POINT TEMPS/POPS...
