These storms propagated southward and downed trees and powerlines.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Aug 31, 3:07 PM CST, 2 hours 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 407 PM CDT SAT AUG 31 2013 .DISCUSSION... CONVECTION HAS FINALLY DEVELOPED NORTH OF A SHORTWAVE TROUGH WHICH WAS CENTERED VERY NEAR KSHV. 12Z SOUNDINGS INDICATED A WEAKER CAP ACROSS SE OK/SRN AR. SFC TEMPS HAVE ALSO SOARED ABOVE 100 DEGREES F WHICH HAS PROVIDED SUFFICIENT INSTABILITY FOR ROBUST CONVECTION. SUB-SEVERE HAIL WILL BE POSSIBLE WITH THE STRONGER UPDRAFTS. LARGE DEW POINT DEPRESSIONS IN THE LOW LEVELS ALSO SUGGEST THE POTENTIAL FOR ISOLATED DAMAGING WIND POTENTIAL...SO A COUPLE OF SEVERE STORMS CANNOT BE COMPLETELY RULED OUT THIS EVENING. MAIN SOURCE OF INSTABILITY IS DIURNAL HEATING. THUS..CONVECTION SHOULD DIMINISH LATER THIS EVENING AFTER SUNSET AND AS THE SHORTWAVE TROUGH CONTINUES TO MOVE SOUTH. A RETURN TO DRY AND HOT CONDITIONS IS EXPECTED AREAWIDE FOR MOST OF SUNDAY. HOWEVER...A WEAK COLD FRONT WILL SLOWLY MOVE SOUTH OF THE I-40 CORRIDOR BY SUNDAY AFTERNOON. THIS FRONT...ALONG WITH ANY UPPER DISTURBANCES ROTATING AROUND THE UPPER RIDGE OVER THE DESERT SW...SHOULD HELP FOCUS THE DEVELOPMENT OF ISOLATED TO WIDELY SCT SHWRS/TSTMS. FRONT WILL BE SLOW TO MOVE SOUTH SO CHANCES FOR CONVECTION SHOULD PERSIST THROUGH LATE TUESDAY NIGHT AND POSSIBLY LINGERING INTO WEDNESDAY AFTERNOON ACROSS DEEP E TX/CNTRL LA.
