along with large hail. These storms developed in a very unstable airmass across the region on the evening of October 1st as a strong upper level storm system exited the southern plains and entered the lower Mississippi valley.

The episode as NWS SHV wrote it up.
Severe thunderstorms accompanied a strong cold front and produced strong and damaging winds...along with large hail. These storms developed in a very unstable airmass across the region on the evening of October 1st as a strong upper level storm system exited the southern plains and entered the lower Mississippi valley.
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 Oct 1, 5:45 PM CST, 1 hour 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 645 PM CDT THU OCT 1 2009 .UPDATE... AN ACTIVE LINE OF CONVECTION CONTINUES TO SLIDE SOUTHEAST ACROSS PORTIONS OF NORTH CENTRAL TEXAS AND SOUTHEAST OKLAHOMA. EXPECTING A CONTINUED THREAT OF SEVERE WEATHER THROUGH THE OVERNIGHT HOURS AS THIS LINE PUSHES THROUGH THE FOUR STATE REGION. AT THIS TIME...THE SEVERE THUNDERSTORM WATCH HAS BEEN EXTENDED EASTWARD AND WILL REMAIN IN EFFECT THROUGH 2 AM. MAIN THREAT WILL BE DAMAGING STRAIGHT LINE WIND AND HAIL. /05/ && .PREV DISCUSSION... /ISSUED 301 PM CDT THU OCT 1 2009/ DISCUSSION... AN ACTIVE NIGHT IS IN STORE FOR THE FOUR STATE REGION. WATER VAPOR IMAGERY THIS AFTERNOON SHOWS A TROUGH DIGGING INTO THE PLAINS STATES WITH A DECENT NEGATIVE TILT TO IT. SURFACE ANALYSIS SHOWS THE ASSOCIATED COLD FRONT IS STRETCHED FROM WESTERN IOWA THROUGH WESTERN MO INTO SOUTHEAST OK AND NORTH CENTRAL TX. RADAR IMAGERY SHOWS A LINE OF STORMS HAVE DEVELOPED JUST AHEAD OF THE FRONT STRETCHED FROM SOUTHWEST MO INTO OK. THERE ARE ALSO SOME ISOLATED SHOWERS AND THUNDERSTORMS THAT HAVE DEVELOPED IN THE WARM SECTOR AHEAD OF THE LINE OF STORMS OVER THE SOUTHERN PORTION OF THE CWFA. THIS ACTIVITY IS CURRENTLY MOVING INTO AN UNFAVORABLE ENVIRONMENT TO DEVELOP INTO ANYTHING SEVERE. HOWEVER...IF THESE STORMS BEGIN TO FORM FURTHER WEST THERE WILL BE ENOUGH INSTABILITY AND LAPSE RATES FOR THE STORMS TO PRODUCE HAIL AND POSSIBLY SOME STRONG WINDS. SO THIS POSSIBILITY WILL HAVE TO BE WATCHED OVER THE NEXT COUPLE OF HOURS. THE MAIN STORY WILL BE A SQUALL LINE THAT WILL MOVE THROUGH THE AREA THIS EVENING AND OVERNIGHT. AS MENTIONED...THE SQUALL LINE IS BEGINNING TO DEVELOP JUST AHEAD OF THE COLD FRONT THIS AFTERNOON. THIS SHOULD BEGIN TO ENTER NORTHWESTERN PORTIONS OF THE CWFA BETWEEN 4 PM AND 7 PM. IT IS EXPECTED TO REACH THE INTERSTATE 30 CORRIDOR BETWEEN 7 PM AND 10 PM. IT IS EXPECTED TO LEAVE THE CWFA BY SUNRISE. THE MAIN CONCERN WITH THIS SQUALL LINE WILL BE DAMAGING WINDS...WITH HAIL BEING A SECONDARY RISK. MODEL SOUNDINGS SHOW THAT HELICITY IS RATHER LOW /BELOW 100 M2/S2/ AND SHOULD NOT BE CONDUCIVE TO TORNADOES. HOWEVER...WILL NOT COMPLETELY RULE OUT THE POSSIBILITY OF ONE OR TWO DEVELOPING WITHIN LINE SEGMENTS. AS THE LINE MOVES THROUGH THE CWFA...THE AREA WILL BE LOSING INSTABILITY. MLCAPES THIS HOUR AHEAD OF THE LINE AROUND 2000 J/KG ARE EXPECTED TO DECREASE TO AROUND OR BELOW 1000 J/KG BY AROUND OR AFTER MIDNIGHT. IN ADDITION...THE BEST UPPER LEVEL DIVERGENCE IS RATHER NORTH OF THE CWFA...SITTING OVER THE MO/NORTHERN AR AREA. SO THE MAIN AREA OF CONCERN WILL BE LOCATIONS ALONG AND NORTH OF THE INTERSTATE 20 CORRIDOR. BUT WILL NOT RULE OUT THE SOUTHERN HALF OF THE CWFA RECEIVING AT LEAST STRONG STORMS WITH OCCASIONAL SEVERE STORMS AS THIS LINE PASSES THROUGH. SURFACE HIGH PRESSURE WILL QUICKLY BUILD BACK INTO THE AREA BEHIND THE FRONT. WE SHOULD SEE SKIES CLEAR RATHER QUICKLY DURING THE DAY ON FRIDAY WITH MUCH DRIER AIR MOVING INTO THE REGION. TEMPERATURES WILL BE COOLER FOR THE WEEKEND AS WE SEE TEMPERATURES STRUGGLING TO GET OUT OF THE 70S BY SUNDAY. THE SURFACE HIGH IS EXPECTED TO DRIFT TO THE EAST OF THE CWFA BY SATURDAY EVENING TO BRING DECENT RETURN FLOW BACK TO THE CWFA FOR THE WORK WEEK. THIS SHOULD BRING A DECENT WARMUP OVER THE CWFA BY THE MIDDLE OF THE WEEK...WHICH WILL GIVE A RETURN OF THE HIGHS IN THE 80S. ALSO THIS RETURN FLOW WILL BRING A DECENT INCREASE IN MOISTURE TO THE CWFA FOR THE LATE WEEKEND AND ESPECIALLY INTO NEXT WEEK. SOUTHERLY SURFACE WINDS WILL CONTINUE THROUGH MUCH OF THE WORK WEEK. IN THE MEANTIME WE SEE ZONAL TO SWLY FLOW ALOFT THROUGH MUCH OF THE WORK WEEK. A SERIES OF IMPULSES PASSING THROUGH THIS UPPER FLOW WILL COMBINE WITH THE ABUNDANCE OF MOISTURE OVER THE REGION TO BRING DECENT RAIN CHANCES THROUGH THE WORK WEEK. THERE WILL BE AN UPPER RIDGE OVER THE GULF OF MEXICO TO THE SOUTH OF THE CWFA...BUT FOR NOW IT IS BELIEVED THAT IT SHOULD REMAIN TOO FAR SOUTH TO HAVE ANY EFFECT ON KEEPING RAIN AWAY FROM THE CWFA. SO THE MAIN CONCERN FOR NEXT WEEK WILL BE THE CONTINUED RAIN CHANCES AND...IF THIS OCCURS...ANY FLOODING PROBLEMS THAT MAY DEVELOP AS A RESULT. THIS WILL HAVE TO CONTINUE TO BE MONITORED AS THERE ARE STILL INCONSISTENCIES BETWEEN MODELS ON HOW NEXT WEEK WILL PAN OUT. OVERALL HAVE MADE FEW CHANGES TO THE FORECAST IN THE EXTENDED AS A RESULT. /22/ AVIATION... FRONT AS OF 18Z WAS LOCATED NEAR A TSA...ABI LINE AND CONTINUES TO MAKE QUICK PROGRESS EASTWARD. IN FACT...THE EASTWARD MOVEMENT IS SLIGHTLY AHEAD OF FCST MODEL MOVEMENT SO HAVE ACCOUNTED FOR THIS IN THE 18Z TAF PACKAGE. AHEAD OF THE FRONT...WE CONTINUE TO SEE SCATTERED SHOWERS ALONG A NARROW CORRIDOR EXTENDING FROM EASTERN OK INTO NE AND CENTRAL TEXAS. THIS ACTIVITY HAS MADE SLOW BUT STEADY PROGRESS EASTWARD THIS AFTERNOON. ELSEWHERE...AHEAD OF THE ACTIVITY WELL INTO THE WARM SECTOR WERE DEVELOPING ISOLATED THUNDERSTORMS ACROSS SE TX WHICH WERE MOVING NORTH IN AN INCREASINGLY UNSTABLE AIRMASS. WILL NEED TO WATCH FOR THIS ISOLATED ACTIVITY INTO SE TX MOVING INTO THE LFK TERMINAL LATER THIS AFTERNOON EVENING. EVENTUAL EVOLUTION OF THE WEATHER FOR THE NEXT 12HRS OR SO IS FOR THE COLD FRONT TO CATCH UP TO THE PRE FRONTAL ACTIVITY WITH STORM MODE EVENTUALLY EXHIBITING A SQUALL LINE OR BOWING SEGMENTS DEVELOPING ACROSS EASTERN OKLAHOMA AND DEVELOPING SOUTHWESTWARD DOWN THE FRONTAL CONVERGENCE ZONE INTO NORTH CENTRAL TEXAS. THUS...HAVE CEILINGS COMING DOWN TO MVFR/IFR WITH VRB WIND GUSTS IN ANTICIPATION OF EASTWARD MOVING SQUALL LINE THROUGH THE NIGHT. QUICKLY BRING POST FRONTAL CEILINGS UP WITH SKIES QUICKLY CLEARING FROM NORTHWEST TO SOUTHEAST TOWARDS SUNRISE FRIDAY MORNING. /13/ && .PRELIMINARY POINT TEMPS/POPS...
