Three supercell thunderstorms developed during the early afternoon hours on the 30th over extreme Eastern Texas and North Louisiana, several hours after scattered showers and thunderstorms spread across the region. The thunderstorms developed along a pair of surface boundaries leftover from the morning convection, with adequate shear and afternoon heating contributing to moderate instability.

The episode as NWS SHV wrote it up.
Three supercell thunderstorms developed during the early afternoon hours on the 30th over extreme Eastern Texas and North Louisiana, several hours after scattered showers and thunderstorms spread across the region. The thunderstorms developed along a pair of surface boundaries leftover from the morning convection, with adequate shear and afternoon heating contributing to moderate instability. One supercell developed over Bowie County Texas and produced damaging winds which downed power lines while also producing copious amounts of small hail which covered the ground. The second supercell developed over Cass County Texas, and moved into Caddo, Desoto, and Sabine Parishes in Northwest Louisiana. This storm produced a large swath of dime to golfball size hail and damaging winds which blew down trees and power lines as it tracked across West and South Shreveport and the east side of Stonewall. The hail fell for nearly 10 minutes across Shreveport, and covered the ground from several inches up to a foot deep over South Shreveport. The third supercell developed over southwest Jackson Parish, which produced damaging winds which downed trees in Jonesboro, Louisiana.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Mar 30, 9:28 AM CST, 3 hours 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 1028 AM CDT SAT MAR 30 2013 .DISCUSSION... UPPER-LEVEL DISTURBANCE PUSHING EAST ACROSS THE REGION THIS MORNING WITH CONVECTION MAINLY CONFINED TO SOUTHERN ARKANSAS AND NORTH LOUISIANA. HOWEVER...WITH ADDITIONAL CONVECTION PUSHING SOUTHEAST ACROSS EASTERN OKLAHOMA AND WESTERN ARKANSAS...MAINTAINED ELEVATED POPS ACROSS THE INTERSTATE 30 CORRIDOR FOR THIS UPDATE. REST OF THE FORECAST LOOKS ON TRACK. EXPECT MOSTLY CLOUDY SKIES THROUGHOUT THE DAY WITH TEMPERATURES APPROACHING 70 DEGREES. WITH SURFACE LOW LINGERING ACROSS CENTRAL TEXAS...COULD SEE ADDITIONAL WARM SECTOR SHOWERS AND THUNDERSTORMS LATER THIS AFTERNOON ACROSS EAST TEXAS AND SOUTHEAST OKLAHOMA. /05/ && .AVIATION... SHORT WAVE TROUGH CENTERED OVER NW LA THIS SATURDAY MORNING TO PUSH E TO MS BY THIS SATURDAY EVENING. ACCORDINGLY EXPECT SLOW IMPROVEMENT FROM CURRENT IFR CEILINGS TO VFR CEILINGS AS PCPN ENDS FROM W TO E IN THE WAKE OF THIS TROUGH DURING LATE THIS SATURDAY MORNING AND THROUGH THIS EVENING. LOW CEILINGS AND VSBY TO RETURN FOR SUNDAY MORNING WITH CONTINUED MOIST SRLY FLOW AND YET ANOTHER SHORT WAVE TROUGH PASSAGE FOR SUNDAY. /VIII./ && .PREV DISCUSSION... /ISSUED 414 AM CDT SAT MAR 30 2013/ DISCUSSION... AN ACTIVE WEATHER SCENARIO EXPECTED FOR THE NEXT FIVE TO SIX DAYS ACROSS THE REGION. FOR TODAY...A STRONG SHORT WAVE IN NORTHWEST FLOW ALOFT WAS BEARING DOWN ON THE CWA. SHOWERS AND A FEW STRONG THUNDERSTORMS WILL BE LIKELY...MAINLY DURING THE MORNING HOURS. BY EARLY AFTERNOON...THE SYSTEM SHOULD BE EAST OF THE CWA...ALLOWING SOME BREAKS IN THE CLOUD COVER. THIS WILL KEEP TEMPERATURES FROM WARMING THROUGH MIDDAY...BUT STILL EXPECT READINGS TO REACH 70 TO 75 MOST AREAS THIS AFTERNOON. NEXT SHORT WAVE NOT FAR BEHIND...AND IT LOOKS LIKE ADDITIONAL SHOWERS AND THUNDERSTORMS WILL REACH THE AREA EARLY SUNDAY. THIS ROUND WILL ALSO BRING A SURFACE FRONT. HOWEVER...WITHOUT SUPPORT ALOFT...THE FRONT LOOKS LIKE IT WILL STALL...POSSIBLY NEAR INTERSTATE 20...CREATING A CONVERGENCE ZONE FOR ADDITIONAL CONVECTION THROUGH SUNDAY NIGHT AND EVEN INTO MONDAY. THEN LATE ON MONDAY...A STRONGER PUSH OF COLD AIR WILL FINALLY REACH THE REGION...DRIVING THE COLD FRONT TO NEAR THE GULF COAST ON TUESDAY. THIS WILL BE FOLLOWED BY A SHIFT IN UPPER PATTERN TO A MORE SOUTHWEST FLOW...AS A TROUGH DIGS INTO THE SOUTHERN ROCKIES. MOISTURE WILL OVERRIDE THE COLDER SURFACE AIR...SETTING UP AN ISENTROPIC RAIN EVENT. EXPECT PERIODS OF RAIN TO CONTINUE UNTIL THE UPPER TROUGH SHIFTS EAST OF THE REGION DURING THE DAY THURSDAY. MODELS ARE STILL IN FAIRLY GOOD AGREEMENT WITH THE PROGRESSION OF EVENTS THROUGH NEXT THURSDAY. HOWEVER...THE ECM NOW HAS THE DEEPER THROUGH OVER THE ARKLATEX BY 12Z THURSDAY. TEMPERATURES WILL REMAIN FAIRLY MILD UNTIL THE COLD AIR ARRIVES MONDAY NIGHT...WITH LOWS MOSTLY IN THE 50S AND LOWER 60S AND HIGHS IN THE 70S. AIRMASS BEHIND THE FRONT WILL BRING LOWS BACK INTO THE 40S MONDAY NIGHT WITH SOME 30S NORTHERN AREAS FOR THE MID WEEK PERIOD. HIGH TEMPERATURES WILL FALL INTO THE 50S AND 60S...BUT SHOULD WARM BACK INTO THE 70S FRIDAY. AVIATION... COMPLEX AND UNCERTAIN FCST TO SAY THE LEAST. LINE OF CONVECTION CURRENTLY MOVING ACROSS N TX SHOULD IS EXPECTED TO BE NEAR A KELD-KSHV/KLFK LINE AROUND THE START OF THE 12Z TAF PERIOD. CONVECTION HAS BEEN STRONG AND OCCASIONALLY SVR AT TIMES BUT SHOULD WEAKEN AS IT CONTINUES TO MOVE SEWD AND ENCOUNTERS A MORE STABLE AIRMASS. HOW FAR SOUTH AND EAST THE LINE CAN MAKE IT IS STILL UNCERTAIN AND WILL PROBABLY BE A LAST MINUTE DECISION FOR THE TAFS BUT SHWRS/TSTMS ASSOCIATED WITH THIS LINE WILL LIKELY CONTINUE TO AFFECT PORTIONS OF E TX AND LA INTO THIS AFTERNOON WHILE BECOMING MORE SCT IN NATURE. FARTHER NORTH...SCATTERED SHWRS/TSTMS OVER CNTRL OK MAY EVENTUALLY AFFECT SE OK/SRN AR AND HIGHER CHANCES FOR REDEVELOPMENT AFTER 31/00Z EXIST IN THIS AREA AS WELL. ABSENT ANY THE CONVECTION...CANNOT RULE OUT SOME LOW STRATUS AND MVFR CONDITIONS AT KLFK THROUGH 30/14Z. OTHERWISE...MOST TERMINALS SHOULD BE VFR FOR MOST OF THE TAF PERIOD BUT A SIMILAR SITUATION IS POSSIBLE EARLY SUNDAY MORNING AND THE DEVELOPMENT OF MVFR/IFR CIGS/VSBYS WILL BE POSSIBLE ONCE AGAIN. DETERIORATING CONDITIONS SHOULD BE EXPECTED WITH ANY TSTMS...INCLUDING IFR/LIFR CONDITIONS AND STRONG GUSTY WINDS. /09/ && .PRELIMINARY POINT TEMPS/POPS...
