The episode as NWS SHV wrote it up.
Strong to severe thunderstorms developed on residual outflow boundaries and heating to produce some wind damage across Northwest Louisiana. There was an upper level disturbance in the vicinity as well which aided in the thunderstorm development. These thunderstorms dissipated just before the midnight hour on June 13th but redeveloped during the morning hours of June 14th.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Jun 13, 2:08 PM CST, 4 hours 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 308 PM CDT WED JUN 13 2012 .DISCUSSION... MCV AND ASSOCIATED UPPER LEVEL SHORTWAVE TROUGH HAVE CONTINUED TO MOVE EAST DURING THE AFTERNOON HOURS. CURRENT POSITION IS JUST TO THE SOUTH OF ARDMORE OKLAHOMA. THIS FEATURE WILL CONTINUE TO MOVE INTO THE FORECAST AREA DURING THE EVENING AND OVERNIGHT HOURS...AFFECTING AREAS MAINLY TO THE WEST AND NORTHWEST OF SHREVEPORT. INSTABILITY IS NOT GREAT OUT AHEAD OF IT...WITH SOME INHIBITION BEING NOTED AS WELL. BUT...HAVE KEPT CHANCE POPS IN THE FORECAST THROUGH THE OVERNIGHT HOURS...AS LIGHT RAIN AND THUNDERSTORMS REMAIN A POSSIBILITY...ESPECIALLY ALONG REMNANT OUTFLOW BOUNDARIES. MAIN CONCERNS IF STRONG STORMS WERE TO DEVELOP WOULD BE DAMAGING WINDS. LOOKING TO THE SOUTHERN PARTS OF THE CWA...A FEW ISOLATED SHOWERS AND THUNDERSTORMS DEVELOPED THIS AFTERNOON EAST OF TOLEDO BEND...SOUTH OF NATCHITOCHES. THIS IS AN AREA WHERE HIGH DEW POINT TEMPS AND POTENTIAL ENERGY CAN BE FOUND. THESE SHOWERS HAVE BEEN GREATLY INFLUENCED BY DAYTIME HEATING AND WILL LIKELY DIMINISH AFTER SUNSET. NORTHWEST FLOW WILL CONTINUE FOR ANOTHER DAY OR SO...AS ANOTHER MCS MAY ORIGINATE NEAR THE TEXAS PANHANDLE TONIGHT. CONFIDENCE IS LOW ON THIS MCS MAKING IT INTO THE CWA TOMORROW. LATE IN THE WEEK AND THROUGH THE WEEKEND...H5OO RIDGE OF HIGH PRESSURE WILL BEGIN BUILDING IN ACROSS THE SOUTHERN PLAINS. A PRETTY ACTIVE WEATHER PATTERN WILL SHAPE UP ACROSS THE NORTHERN PLAINS...WITH SEVERAL LONG WAVE TROUGHS MOVING THROUGH THE AREA. THIS ACTIVE WEATHER WILL KEEP THE UPPER RIDGE IN PLACE ACROSS THE SOUTHERN STATES. RAIN CHANCES AFTER TONIGHT AND TOMORROW WILL NOT BE GREAT. THEY MAY COME IN THE FORM OF ISOLATED AFTERNOON THUNDERSTORMS ASSOCIATED WITH DAYTIME HEATING AND SOUTHERLY FLOW AROUND SURFACE HIGH PRESSURE. /20/ && .AVIATION... A FEW SHOWERS AND THUNDERSTORMS HAVE STARTED TO DEVELOP ACROSS CENTRAL LA IN A MORE ISOLATED VARIETY. MEANWHILE...A FEW STORMS ARE ALSO TRYING TO DEVELOP ACROSS NE TX AND SE OK ON THE EAST SIDE OF A REMNANT MCV. HOWEVER...IT APPEARS THE ATMOSPHERE MAY BE JUST STABLE ENOUGH TO PREVENT ANYTHING SIGNIFICANT FROM DEVELOPING ATTM. HAVE PUT VCTS AND TSRA IN SITES ACROSS EAST TX AND NW LA LATER THIS AFTERNOON IN ANTICIPATION THAT SOMETHING WILL DEVELOP AHEAD OF THE MCV...BUT CHANCES APPEAR TO BE IN THE 20 TO 40 PCT RANGE. EXPECT MAINLY VFR EXCEPT FOR THE SHOWERS AND STORMS THROUGH THE OVERNIGHT WITH SOME POSSIBLE MVFR CLOUDS IN THE EARLY MORNING HOURS ACROSS MOST SITES WHICH WILL CLEAR UP BY ABOUT 15Z. WINDS WILL GENERALLY BE LIGHT AND OUT OF THE SOUTHEAST THROUGH THURSDAY AM. /04/ && .PRELIMINARY POINT TEMPS/POPS...
