The episode as NWS SHV wrote it up.
Isolated to scattered showers and thunderstorms continued to develop throughout the day across Northcentral Louisiana as they rotated west southwest around a slow moving upper level storm system off of the Mississippi and Alabama coasts. Isolated strong thunderstorms continued during the evening across Southeast Arkansas, which moved southwest into Eastern Union Parish and briefly became severe as they moved through the Marion community. A microburst resulted in damaging winds which blew down a large tree onto power lines and a nearby vehicle. The storm weakened shortly after it exited Marion.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Jun 6, 5:11 PM CST, 3 hours 7 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 611 PM CDT Tue Jun 6 2017 .AVIATION... Isolated to scattered -SHRA/-TSRA noted near kmlu and TSRA has impinged klfk resulting in brief moderate to heavy rainfall. This activity continued to progress southwest and will not affect the said terminal for long. Have elected to maintain a prevailing -SHRA VCTS and a variable southeast gusty wind mention at klfk for the next few hours. Otherwise, winds will prevail between a northerly and a east-northeasterly wind overnight with speeds of 2-6 kts. Winds will increase into the 10-15 kt range sustained with higher gusts, from the north-northeast late Wednesday morning/early afternoon. SKC-SCT VFR CIGS occurring across all but klfk due to the prevailing precipitation activity with MVFR CIGS plaguing the site. Should see CIGS improve to VFR in the next few hours, with computer models hinting at the potential for MVFR CIGS returning overnight at klfk. Furthermore, patchy VFR fog may also develop near klfk but confidence is not high enough to insert a mention at this time, due to wind speeds staying up a bit there overnight. Dry conditions will prevail once this precipitation activity diminishes aoa sunset. && .PREV DISCUSSION... /issued 258 PM CDT Tue Jun 6 2017/ DISCUSSION... Scattered to numerous shwrs/tstms continue to pivot around the back side of the upper low centered over ern LA/wrn MS. These will continue to affect portions of our region from near Lufkin, TX to El Dorado, AR through the daylight hours. Would not be surprised to see some of this convection bring minor flooding to low-lying and poor drainage areas today, as rain rates of late have been quite efficient. Latest HRRR, as well as the mainstream model output show convection dying out shortly after sunset, as the upper low continues to drift ewd and we lose daytime heating. Region to see some drier weather for the next several days, as nw flow aloft and high pressure at the sfc dominates the pattern. Have held close to blended guidance for temps during this timeframe, but we could be warmer if the soils dry out quickly. There will certainly be enough sunshine to warrant it otherwise. Piece of energy will break off of the main flow over TX as we move into the weekend, and this will set us up for a return of sct convection for Sunday into next work week, as the upper flow turns more swly and low level moisture makes a quick return. /12/ && .PRELIMINARY POINT TEMPS/POPS...
