The episode as NWS SHV wrote it up.
Strong to severe thunderstorms developed in Smith County, Texas during the afternoon hours of June 18th. The atmosphere became moderately unstable as a series of upper level disturbances moved south and east across the region. The atmosphere was very moist and with little if any capping inversion in the atmosphere, thunderstorms quickly developed and matured, producing strong damaging wind gusts.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 1133 AM CDT TUE JUN 18 2013 .DISCUSSION... SCT CONVECTION REMAINS ONGOING THIS MORNING ACROSS NCNTRL LA...IN VC OF A WEAK SFC FRONT WHICH WAS EVIDENT A BIT EARLIER IN THE VISIBLE SATELLITE LOOPS JUST ENTERING UNION AND CLAIBORNE PARISHES AND EXTENDING W ALONG THE AR/LA LINE TO NEAR JXI...TO JUST S OF JDD...AND FARTHER W INTO NCNTRL TX. THE VIS LOOP ALSO INDICATES AN ELEVATED BNDRY AHEAD OF THE CNTRL TX CONVECTION EARLIER WHICH HAS SHIFTED E INTO NE...CNTRL AND SW LA INTO SE TX. WEAK PRESSURE RISES ACROSS AR HAS ALLOWED THE FRONT TO SAG A LITTLE FARTHER S INTO EXTREME NRN LA THIS MORNING...WITH THE MSAS SFC THETA-E PLOTS INDICATING RAINCOOLED AIR ALONG AN OUTFLOW BNDRY FROM EARLIER CONVECTION BISECTING NCNTRL LA FROM NEAR SHV...SE TO IER AND ESF. WRLY FLOW IN THE LOWEST 3 KM HAS YIELDED ENOUGH CONVERGENCE ALONG THE SFC AND ATTENDANT 850MB TROUGH...AND NCNTRL LA OUTFLOW BNDRY FOR A PERSISTENT REGENERATION OF CONVECTION THIS MORNING WITH AID OF WEAK PVA ALOFT...BUT BELIEVE THIS SHOULD DIMINISH SOMEWHAT BY EARLY AFTERNOON AS THIS PVA GRADUALLY WEAKENS. FARTHER W...THE 16Z SFC ANALYSIS INDICATES AN OUTFLOW BNDRY FROM THE EARLY MORNING CNTRL TX CONVECTION WHICH HAS SLOWED AS IT ENTERED SE TX...AND EXTENDS ROUGHLY FROM A CLL...TO JUST E OF A CRS LINE. VIS IMAGERY AND MOSAIC RADAR LOOPS ALSO REVEAL AN MCV SPINNING JUST SW OF DFW...WHICH REMAINS PROGGED TO SHIFT ESE INTO E TX THIS AFTERNOON AND INTO NCNTRL LA THIS EVENING. THE AIR MASS REMAINS RELATIVELY UNTOUCHED ACROSS PORTIONS OF DEEP E TX LATE THIS MORNING...WITH SBCAPES OF 2500-3000 J/KG ALREADY AS OF 16Z. THUS...SCT CONVECTION SHOULD DEVELOP EXPAND ENE ACROSS E TX WITHIN THE NEXT COUPLE OF HOURS...WITH ISOLATED STRONG STORMS POSSIBLE OVER DEEP E TX GIVEN THE STRONGER INSTABILITY...AND INCREASE IN 0-6KM SHEAR AS IT APPROACHES 20-30KTS NEAR THE MCV. THE AIR MASS THAT HAS BEEN WORKED OVER FARTHER N AND E MAY STRUGGLE WITH MORE CONCENTRATED CONVECTION IN A LESS WEAKLY SHEARED AIR MASS...BUT GIVEN THE VERY SATURATED NATURE OF THE AIR MASS /THE KSHV 12Z RAOB REVEALED A PW OF 2.17 INCHES...AND A WARM LAYER OF 3.7KM DEEP/...IT SHOULD NOT TAKE MUCH TO YIELD ADDITIONAL CONVECTION GIVEN THE MYRIAD OF SFC BNDRYS IN PLACE. LOCALLY HEAVY RAINFALL WILL BE POSSIBLE IN THE STRONGER STORMS AS THEY WILL BE EFFICIENT RAIN PRODUCERS...WITH AN ISOLATED FLOOD THREAT POSSIBLE ESPECIALLY WHERE STORMS TRAIN. COCORAHS REPORTS FROM NEAR MINDEN LA HAVE REPORTED 5.5-6.25 INCHES OF RAIN IN THE LAST 24 HRS...WITH 4.5-5+ INCHES OF THIS FALLING EARLY THIS MORNING. AND HOURLY RAIN RATES AS CONVECTION MOVED OVER KSHV WAS NEAR 2.50 IN/HR. HAVE CONCENTRATED HIGH CHANCE POPS GENERALLY ALONG/S OF I-20 ACROSS E TX/N LA TODAY...S OF THE FRONT AND AHEAD OF THE APPROACHING MCV. HAVE TAPERED POPS TO LOW CHANCE AND SLIGHT CHANCE FARTHER N ACROSS EXTREME NE TX/SW AR...AND HAVE DROPPED POPS TODAY FOR SE OK AND THE FAR NRN SECTIONS OF SW AR. THE EXTENSIVE CLOUD COVER AND CONVECTION WILL LIMIT AFTERNOON HEATING...THUS HAVE LOWERED TEMPS A FEW DEGREES INTO THE MID/UPPER 80S AREAWIDE. ZONE UPDATE ALREADY OUT...GRIDS WILL BE AVAILABLE SHORTLY. 15 && .AVIATION... MAIN CONCERN FOR THE 18/18Z TAF ISSUANCE WILL BE FLIGHT HAZARDS FROM SCATTERED TSTMS WHICH WILL PREVAIL FOR MUCH OF THE AFTERNOON INTO THIS EVENING. A WEAK FRONTAL BOUNDARY NEAR A KELD TO KJDD LINE WILL BE THE DIVIDING LINE BETWEEN MORE NUMEROUS STORMS TO THE SOUTH AND ONLY ISOLATED COVERAGE NORTH. EXPECT MOSTLY VFR FLIGHT WEATHER OUTSIDE OF THE CONVECTIVE AREAS...BUT NEAR STORMS EXPECT MVFR/IFR CONDITIONS ALONG WITH MODERATE TO SEVERE TURBULENCE AND SURFACE WIND GUSTS UP TO 35 KTS. THE FRONT WILL DRIFT SOUTH TONIGHT AND MOST OF THE CONVECTION WILL REMAIN SOUTH OF THE BOUNDARY. HOWEVER AFTER 08Z AND CONTINUING THROUGH 14Z WEDNESDAY....MUCH OF THE AREA ALONG AND SOUTH OF INTERSTATE 20 MAY EXPERIENCE MVFR TO BRIEFLY IFR CIGS AND SOME MVFR VISIBILITY DUE TO FOG. SURFACE WIND WILL BE DETERMINED BY FRONTAL LOCATION...BUT GENERALLY IN THE 5 TO 10 KT RANGE. /14/ && .PRELIMINARY POINT TEMPS/POPS...
