The episode as NWS SHV wrote it up.
A deep upper level trough was nearly stationary across south central Texas with thunderstorms developing to the north and east of the trough during the morning hours of June 9th. The storms propagated into northeast Texas during the afternoon of the 9th and encountered a very unstable airmass. These storms become widespread across the region into the afternoon and evening hours of the 9th and produced large hail along with damaging thunderstorm wind gusts. Some of the storms were prolific rain producers with isolated reports of flash flooding. During the late evening hours of the 9th...storms began to redevelop closer to the trough of low pressure which was located just west and south of Tyler, Texas. These storms trained across the same general area and were prolific rainfall producers...especially across northeast Texas. Widespread flooding was common across portions of northeast Texas and this flooding continued into the day of the 10th.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Shreveport, LA wrote its last area forecast discussion before the first event at Jun 9, 9:08 AM CST, 1 hour 52 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 1008 AM CDT WED JUN 9 2010 .DISCUSSION... HAD TO MAKE SOME SIGNIFICANT CHANGES TO THE FORECAST THIS MORNING...MAINLY TO RAISE POPS CONSIDERABLY FOR MUCH OF E TX...AND BUMP POPS BACK UP FOR THE REMAINDER OF THE AREA FOR THE AFTERNOON. NEW TOR WATCH #286 HAS BEEN ISSUED FOR MUCH OF ERN/SE TX THROUGH 20Z...TO ACCOUNT FOR STRONG/SVR CONVECTION DEVELOPING IN A VERY WARM/MOIST/UNSTABLE AIR MASS...EVIDENT ON THE 12Z KSHV/KLCH RAOBS E OF THE CLOSED LOW OVER CNTRL TX. IN FACT...THE 14Z LAPS ANALYSIS INDICATES SFC BASED CAPES APPROACHING 2500 J/KG OVER MUCH OF DEEP E TX/NCNTRL LA...AS MID/UPPER 70S DEWPOINTS CONTINUE TO SPREAD NNW INTO THE AREA...S OF AN INVERTED SFC TROUGH. THE 14Z SFC ANALYSIS INDICATES THE TROUGH EXTENDING FROM JUST SW OF THE DFW METROPLEX...SE TO NEAR TYR...TO NEAR AQV...WHICH IS EXPECTED TO GRADUALLY LIFT N THROUGH THE DAY. THIS TROUGH WILL LIKELY SERVE AS FOCUS FOR THE HEAVY RAINFALL FOR THE AFTERNOON...ALONG WITH ANY OTHER MESOSCALE BOUNDARIES PRODUCED FROM TODAY/S CONVECTION. MOSAIC RADAR LOOP INDICATES A MCV OVER SRN MILAM COUNTY TX NEAR ROCKDALE...WITH ANOTHER MCV INDICATED OVER ERN HILL AND ELLIS COUNTIES JUST S OF DAL...CLOSER TO THE SFC TROUGH...DRIFTING N. GIVEN THE STRONG DIVERGENCE IN PLACE E OF THE CLOSED LOW...AND DEEP WARM NOSE ON THE 12Z KSHV/FWD RAOBS NEARING 4KM...VERY HEAVY RAINFALL AND THE POTENTIAL FOR FLASH FLOODING WILL BE THE MAIN THREATS WITH THIS SYSTEM. MUCH OF E TX CAN TAKE THE INITIAL ONSET OF HEAVY RAINFALL TODAY...AS CONVECTION HAS BEEN MOVING RAPIDLY THIS MORNING OVER A VERY DRY GROUND. HOWEVER...THE 06Z GFS HAS A GOOD HANDLE ON THE CURRENT CONVECTION...WITH ADDITIONAL REDEVELOPMENT LIKELY OVERNIGHT THROUGH MUCH OF THURSDAY OVER E TX/SE OK/SW AR AS THE LOW BEGINS TO DRIFT NE. THUS...A FLASH FLOOD WATCH FOR A PORTION OF THESE AREAS MAY BE NEEDED WITH THE AFTERNOON FORECAST...AS ADDITIONAL MODEL DATA IS ANALYZED. A SVR THREAT IS NOT OUT OF THE QUESTION AS WELL TODAY...AS THE LEDBETTER TX PROFILER INDICATES A STRONG/UNIDIRECTIONAL 40KT 1KM JET IN PLACE AHEAD OF THE SRN MOST MCV...IN THE VERY MOIST/UNSTABLE AIR MASS IN PLACE. CONVECTION CONTINUES TO GUST E INTO CHEROKEE/ANGELINA COUNTIES ATTM...ALTHOUGH...WHEN INTERACTING WITH THE SFC TROUGH...COULD PROVIDE ENOUGH DIRECTIONAL SHEAR FOR AN ISOLATED/BRIEF TORNADO SPINUP. DAMAGING WINDS WILL BE POSSIBLE AS WELL FROM THE STRONGER STORMS...ALTHOUGH 0-3KM SHEAR WEAKENS AS YOU MOVE E INTO NCNTRL LA. ALSO LOWERED MAX TEMPS THIS AFTERNOON OVER E TX...AND MADE MINOR ADJUSTMENTS ELSEWHERE AS NEEDED. HOWEVER...THE WARMEST TEMPS WILL REMAIN OVER THE ERN SECTIONS OF NCNTRL LA TODAY...AS THEY WARM TO THE LOWER/POSSIBLY MID 90S...RESULTING IN HEAT INDICES OF 100-105 DEGREES. UPDATE PRELIMS TO FOLLOW BELOW... 15 && .AVIATION... SCATTERED SHRA AND TSRA ACTIVITY IS EXPECTED ACROSS THE FOUR STATE REGION AS AN UPPER LOW OVER SOUTH CENTRAL TEXAS CONTINUES TO MOVE TOWARD THE AREA. THE MOST WIDESPREAD ACTIVITY WILL AFFECT EAST TEXAS SITES THROUGH THE DAY AND INTO THIS EVENING. MOST TERMINALS ARE SEEING VFR CONDITIONS THIS MORNING. HOWEVER A FEW SITES IN EAST TEXAS MAY CONTINUE TO SEE STRATUS THROUGH MID TO LATE MORNING. THERE WILL BE PERIODS WHERE CIGS AND VSBYS ASSOCIATED WITH +TSRA ACTIVITY WILL REDUCE TO IFR FLIGHT CATEGORIES...ESPECIALLY FOR EAST TEXAS SITES. THESE PERIODS OF LOWER FLIGHT CATEGORIES WILL BE COVERED MAINLY BY TEMPO GROUPS FOR THE 18Z TAF PACKAGE. OVERALL EXPECT THE MAJORITY OF SHRA AND TSRA ACTIVITY TO OCCUR DURING THE DAYTIME WITH HEATING. HOWEVER...ISO TO SCT SHRA SHOULD PERSIST THROUGH THE FORECAST PERIOD AS THE UPPER LOW IS EXPECTED TO CONTINUE TO DRIFT NORTH ACROSS WESTERN PORTIONS OF THE FOUR STATE REGION THROUGH THE TAF PERIOD. OTHERWISE EXPECT WINDS TO BE OUT OF THE SOUTH TO SOUTHEAST BETWEEN 5 AND 10 KTS TODAY AND TONIGHT...POSSIBLY A LITTLE LIGHTER FOR EASTERN SITES INCLUDING ELD AND MLU.
