The episode as NWS SHV wrote it up.
An outbreak of severe weather occurred across portions of northeast Texas and northwest Louisiana during the early morning hours and afternoon hours of April 25th. This weather was spawned by a strong area of low pressure in the upper levels of the atmosphere across Oklahoma and southern Kansas. Strong shear developed during the day |across the region...resulting in thunderstorms producing flash flooding...large hail and damaging thunderstorm wind gusts.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Apr 24, 9:10 PM CST, 5 hours 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 1010 PM CDT TUE APR 24 2007 .DISCUSSION... AREA RADARS SHOW A BUSY NIGHT ACROSS TEXAS...AS SQUALL LINES DEVELOP AHEAD OF THE DRYLINE. UPPER TROUGH IS NOW CENTERED OVER EXTREME SW KS...AND JUST BEGINNING TO PUSH THE DRYLINE OFF THE CAPROCK. KSHV 00Z SOUNDING WAS STILL QUITE CAPPED...AND ASIDE FROM THE EARLIER SQUALL LINE THAT MOVED THROUGH SE OK/SW AR...CONVECTION HAS BEEN HARD TO MAINTAIN IN THE CWA. ALSO OF NOTE IS A WET-BULB ZERO IN EXCESS OF 12 KFT...POSSIBLY WHY HAIL REPORTS WERE NON-EXISTENT OR UNIMPRESSIVE. HOWEVER...MID-LEVEL LAPSE RATES...HELICITY...AND SHEAR FROM THE SOUNDING WARRANT LEAVING IN A MENTION OF SEVERE WX THE REST OF THE NIGHT. LATEST ETA IS TRICKLING IN...AND FORECAST SOUNDINGS FOR KSHV SHOW THE CAP ERODING BETWEEN 06-09Z...SO NOT MUCH CHANGE TO CURRENT WX GRIDS. WE/LL ONLY UPDATE TO CURRENT CONDITIONS. UPDATES WILL GO OUT AT 04Z...WHEN TORNADO WATCH 176 EXPIRES...AND POSSIBLY OTHER WATCHES ISSUED. && .AVIATION... MVFR AND VFR CIGS CONTINUE THIS AFTERNOON.

VERY POTENT CLOSED LOW NEAR PANHANDLE REGION WILL MOVE SLOWLY ESE ACROSS OK TONIGHT AND WED. SCATTERED TSTMS DEVLOPING FROM FTW INTO SE OK. FURTHER WEST...BROKEN LINE TSTMS ALONG DRYLINE. THUS...ALREADY TWO REGIONS OF CONCERN...WITH CONVECTION POSSIBLE ALONG SECONDARY BOUNDARIES LATER TONIGHT. 18Z SOUNDING AT FTW SHOWED A SIX HOUR INCREASE IN K INDEX FROM 19 TO 37...AND HELICITY AROUND 200 WITH 45 KNOT LOW LEVEL JET. MODEL SOUNDING INDICATE THIS MODERATELY HIGH HELICITY TO INCREASE. IN ADDITION...SOUTHERLY UPPER JET IN EXCESS OF 100 KNOTS AHEAD OF UPPER LOW WILL SERVE BOTH TO PUMP DEEP MOISTURE ACROSS EAST TX LATER TONIGHT...AND TO PRODUCE EXTREME UPPER DIVERGENCE OF BOTH SPEED AND DIRECTIONAL COMPONENT. SATURATED COLUMN AND POSSIBLE SLOWING OF SYSTEM DUE IN PART TO OBSTRUCTION OF SUCH A STRONG SOUTHERLY UPPER LEVEL JET...TRANSITION MORE FROM SEVERE TO VERY HEAVY RAIN EVENT. IN THE MEANTIME...DRY AIR ABOVE LOADED GUN SHAPED SOUNDINGS ENHANCE SEVERE THREAT...ESPECIALLY FOR LARGE HAIL. AS FFG VALUES FAIRLY HIGH... WILL WAIT A FEW HOURS BEFORE DECIDING ON FLOOD WATCH. OTHER QUESTION WILL BE EXISTENCE AND INTENSITY OF ANOTHER ROUND OF TSTMS RIGHT ALONG FRONT DURING DAY ON WED. INHIBITING FACTOR WILL BE A VERY WORKED OVER AIRMASS BY THAT TIME AND DRY SLOTTING FROM SE TX. WEAK FRONT WILL DRAG INTO AT LEAST NORTHERN PORTIONS OF AREA WITH SHORTWAVE IN NW FLOW ALOFT FRIDAY NIGHT. PUT IN LOW CHANCE POPS. NEXT WEEK PREDOMINATE SOUTHERLY FLOW.
