The episode as NWS SHV wrote it up.
Overnight...strong to severe thunderstorms developed across Southeast Oklahoma and move southward across McCurtain County, Oklahoma. These thunderstorms developed due in part to moderate instability at the surface and a disturbance aloft moving from north to south. These storms were prolific rain producers and produced strong and damaging wind gusts.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 331 AM CDT MON SEP 2 2013 .DISCUSSION... FRONTAL BOUNDARY SAGGING SLOWLY SOUTH INTO NE TX AND EXTREME NORTHERN LA BY MIDDAY...WILL BRING ONGOING SCATTERED COVERAGE OF CONVECTION ALONG BOUNDARY. ISOLD LGT STRIKES OVERNIGHT SHOULD INCREASE WITH DAYTIME HEATING. HIGH BASED STORMS WITH STEEP LAPSE RATES IN LOW LVLS WILL CREATE CONDITIONS CONDUCIVE FOR STG GUSTY WINDS NEAR CELLS AND PCPN WATER VALUES COULD BRING BRIEF HEAVY RAINFALL DESPITE DRIER PORTIONS OF COLUMN GENERALLY IN LOW LVLS. THIS FRONTAL BOUNDARY WILL MOVE SLOWLY SOUTH ACROSS REGION...SO THAT SOUTHERN PORTIONS OF REGION WILL SEE MAINLY DUIRNAL ISOLD TO SCATTERED COVERAGE OF CONVECTION ON TUE...AND POSSIBLY AT LEAST THRU WED. HOWEVER...PERSISTENT LARGE UPPER RIDGE OVER WESTERN STATES WILL KEEP NE FLOW IN MID TO UPPER LVLS...AND TEMPERATURES UNSEASONABLY WARM...ALBIET MAINLY BELOW THE CENTURY MARK FINALLY...THRU REMAINDER OF FCST PERIOD.
