Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS SHV wrote it up.
A strong upper level trough moved out of the Texas Hill Country...towards the region during the late morning, afternoon and evening hours of May 9th. Strong instability developed across the region with peak heating and a strong capping inversion initially during the morning broke during the day. Scattered strong to severe thunderstorms developed in the unstable airmass with large hail and damaging thunderstorm wind gusts the primary result. Some of these storms trained across the same general area...producing copious amounts of rainfall. A Flash Flood Warning was prompted for San Augustine County as a result.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at May 9, 4:20 AM CST, 5 hours 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 520 AM CDT FRI MAY 9 2014 .DISCUSSION... LAST NIGHT/S THUNDERSTORMS CONTINUE TO PUSH ACROSS THE SOUTHEASTERN THIRD OF THE CWA. MEANWHILE...A FEW NEW THUNDERSTORMS ARE CROPPING UP JUST TO OUR SOUTHWEST IN THE CORSICANA AND WACO VICINITIES AS ANOTHER UPPER VORT LIFTS ACROSS THE RIO GRANDE. AT THIS TIME...GENERALLY WE SEE WARM TEMPERATURES WHERE RAIN HAS ENDED AND SOME LIGHT TO PATCHY DENSE FOG WILL BE POSSIBLE OVER THE WET SOIL FOR A FEW HOURS. THERE ARE SEVERAL LOWER 60S ASSOCIATED WITH THE THUNDERSTORMS STRETCHING FROM NATCHITOCHES...TO MONROE. THE WATER VAPOR SHOWS THE COLDER AIR ALOFT PUSHING IN OVER THE FOUR STATE AREA AND WILL HELP TO CROP UP MORE SHOWERS AND THUNDERSTORMS AREA WIDE TODAY...ALBEIT MORE SCATTERED AROUND IN POCKETS COMPARED TO LINES. HOWEVER...LATE DAY THE COVERAGE MAY BECOME A BIT MORE ENHANCED AND ORGANIZED AS THE UPPER LEVEL ENERGY HELPS TO FOCUS THE DAYTIME HEATING. INTO THE EVENING...A BACK EDGE WILL LIKELY EMERGE AND BEGIN TO PUSH ACROSS THE REGION. WPC QPF IS GENERALLY HIT OR MISS TENTHS AND QUARTER INCH AMOUNTS AND WE CAN TAKE MORE WELL EVEN AFTER THE GOOD SOAKING FOR MANY LOCALES YESTERDAY. THE SPC HAS A SLIGHT RISK OUT FOR TODAY FOR MUCH OF THE FOUR STATE AREA AS THE UPPER VORT OVER MEXICO AND W TX SWINGS EAST...THEN NORTHEAST IN THE UPPER TROUGH MAINLY FOR DAMAGING WINDS OR MAYBE SOME HAIL WITH THE COLDER TEMPS ALOFT. OVERALL...WE ARE CLOSE TO MAV GUIDANCE FOR THE SHORT TERM AND MEX IN THE LONGER TERM. IT STILL LOOKS LIKE THE COLD FRONT WILL STAY PUT TODAY ACROSS OK AND EVEN LIFT BACK NORTH LATER WHILE PUSHING ACROSS MO. THE WEEKEND WILL SEE A SLIGHT CHANCE LINGER FOR SOME POP CORN SHOWERS AND THUNDERSTORMS IN THE WARMER TEMPERATURES THAT WILL OCCUR IN THE AREA AND EVEN WARMER AND BREEZY FOR MOTHERS DAY. THE COLD FRONT STILL LOOKS TO MOVE INTO THE REGION LATE MONDAY AND EARLY TUESDAY AND WILL HELP TO FOCUS CONVECTION YET AGAIN FOR MUCH OF THE AREA WITH THE GFS LOOKING EVEN WETTER AS THE UPPER TROUGH DIGS THE JET OVER THE FRONT AS A 1025 MB SURFACE HIGH BUILDS DOWN THE FRONT RANGE INTO THE MID SOUTH BY MIDWEEK. AFTER LOOKING AT CRACKED GROUND IN MANY LOCALES...THIS WET PATTERN IS MORE THAN WELCOMED TO THE FOUR STATE AREA. && .PRELIMINARY POINT TEMPS/POPS...
