The episode as NWS JAN wrote it up.

The majority of the severe weather, as well as the hardest hit areas, occurred across the northern portions of forecast area, especially over northern Mississippi. A mix of hail and damaging winds occurred during the event.

NWS Jackson, MS wrote its last area forecast discussion before the first event at Jun 12, 11:25 AM CST, 2 hours 27 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 1225 PM CDT FRI JUN 12 2009 .UPDATE...HIGH PRESSURE IS HANGING TOUGH OVER OUR SOUTH AND SHOULD CONTINUE TO SUPPRESS CONVECTION THERE AGAIN THIS AFTERNOON. ALL EYES ARE ON THE COMPLEX MOVING OVER NORTHWEST ARKANSAS THAT IS EXPECTED TO TRACK ESE ALONG THE STALLED FRONTAL BOUNDARY THIS AFTERNOON INTO THE EVENING. THIS COMPLEX SHOULD HOLD TOGETHER AND MOVE INTO OUR NORTHERN ZONES LATER THIS AFTERNOON AND CONTINUE ESE INTO THE EVENING. HAVE INCREASED POPS ACROSS THE NORTHWEST THIS AFTERNOON AND ADDED SEVERE WORDING POTENTIAL. MAIN THREATS WILL BE DAMAGING WINDS AND HAIL. FORECAST WAS UPDATED TO INCLUDE CURRENT SEVERE THUNDERSTORM WATCH THAT RUNS UNTIL 7PM FOR OUR NW DELTA COUNTIES. REMAINDER OF FORECAST WAS ON TRACK. /22/ .PREVIOUS DISCUSSION...SHORT TERM...TODAY THROUGH SATURDAY NIGHT...SATELLITE THIS MORNING SHOWS AN EXTENSIVE PLUM OF CIRRUS SPREADING EAST ACROSS THE FORECAST AREA FROM A LARGE MCS THAT CONTINUES TO DECAY AS IT DROPS SOUTHWARD ACROSS SOUTHEAST TEXAS. RADAR DOES SHOW SOME ACTIVITY DEVELOPING ACROSS SOUTH CENTRAL ARKANSAS ALONG AN AREA OF CONVERGENCE THIS MORNING. THIS ACTIVITY IS MOVING TO THE EAST AND IF IT HOLDS TOGETHER...WILL AFFECT PORTIONS OF MY NORTHWEST ZONES. THERES NOT MUCH IN THE WAY OF CONFIDENCE AS TO HOW THINGS WILL PAN OUT OVER THE NEXT 48 HOURS. A BOUNDARY CONTINUES TO SINK SOUTH ACROSS THE MID SOUTH THIS MORNING. MY THINKING IS AS IT CONTINUES TO DO SO...ITLL BE ENOUGH FORCING TO COMBINE WITH THE WARM... MOIST...AND UNSTABLE AIRMASS OVER THE AREA ALLOWING FOR SOME ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS TO DEVELOP OVER AREAS MAINLY NORTH OF INTERSTATE 20 TODAY. BECAUSE OF THIS AND GIVEN THE CURRENT ACTIVITY MOVING INTO MY NORTHWEST COUNTIES...IVE INCREASED POPS ACROSS THE NORTHERN PORTION OF THE CWA TODAY. AN ISOLATED STORM OR TWO COULD BE ON THE STRONG TO SEVERE SIDE LATER TODAY. THUS...ILL CONTINUE TO HIGHLIGHT THIS IN THE HWO. CONFIDENCE IS EVEN LOWER FOR TONIGHT AS MODELS DIVERGE ON WHETHER OR NOT A COMPLEX OF STORMS IS GOING TO DEVELOP TO THE WEST AND SHIFT EAST ACROSS NORTHERN PORTIONS OF THE FORECAST AREA. I THINK ANY ACTIVITY WE SEE THIS AFTERNOON ACROSS THE NORTH COULD LINGER INTO THE EVENING AND OVERNIGHT HOURS. HOWEVER...AS FOR FORECASTING A COMPLEX OF STORMS RACING EAST ACROSS THE NORTHERN HALF OF THE CWA THROUGH THE NIGHT...MUCH ATTENTION IS GOING TO HAVE TO BE PAID THIS EVENING TO SATELLITE...RADAR...AND OTHER FORMS OF REAL TIME DATA TO REALLY GET SOME KIND OF DECENT FEEL AS TO WHATS GOING TO TRANSPIRE LATER TONIGHT. WHILE THE CHANCE OF A COMPLEX OF STORMS AFFECT THE AREA TONIGHT EXISTS...MODELS WITH THIS PATTERN HAVE JUST BEEN TOO INCONSISTENT AND UNRELIABLE TO PUT ANY FAITH IN THEM. RAIN CHANCES WILL AGAIN EXIST ACROSS THE NORTH ON SATURDAY. THE BETTER CHANCES HOWEVER WILL BE DURING THE EARLY PART OF THE DAY. MODELS BEGIN TO STRENGTHEN THE PRESENCE OF THE UPPER RIDGE AND SURFACE HIGH ACROSS THE REGION DURING THE DAY AND THROUGH SATURDAY NIGHT...WHICH SHOULD START TO LIFT THE BOUNDARY BACK TO THE NORTH AND AWAY FROM THE FORECAST AREA. HOT AND HUMID CONDITIONS WILL PERSIST THROUGH THE AFTERNOON AS HIGHS WARM INTO THE LOW TO MID 90S AND LOWS SATURDAY NIGHT FALL INTO THE LOW AND MID 70S. /19/ LONG TERM...THE WEATHER STORY IN THE EXTENDED CONTINUES TO BE THE EFFECT OF WEAK TRANSIENT WAVES ON A STRONG UPPER RIDGE THAT WILL BE PARKED OVER THE AREA. MODELS AGREE THAT WEAK WAVES WILL OCCASIONALLY LIFT OVER THE NRN EDGES OF UPPER RIDGING OVER THE ARKLAMISS REGION TO MAINTAIN A SLIGHT CHANCE OF CONVECTION...MAINLY OVER NRN ZONES. THE MORE PRONOUNCED LOW LEVEL TROUGHING IS FORECAST TO REMAIN WELL N OF THE FORECAST AREA ALTHOUGH THE EURO REMAINS CONSISTENT IN MAINTAINING WEAK SURFACE CONVERGENCE AS IT PARKS THE REMNANTS OF A BOUNDARY ACROSS THE AREA. WITH 500 MB HEIGHTS AT OR ABOVE 588 DAM AND GENERALLY ANTICYCLONIC FLOW AT 850 MB WE WILL HAVE SIGNIFICANT SUBSIDENCE TO OVERCOME. ALTHOUGH THE EURO POSTS THE STRONGEST RIDGING OVER THE REGION THROUGH THE EXTENDED...THE GFS SHIFTS THE RIDGE CENTER SLIGHTLY WWD BY MID WEEK TO SUGGEST A BETTER CHANCE OF ISOLATED CONVECTION. IF THE GFS SOLUTION OCCURS THEN THE DOOR WILL OPEN FOR ANOTHER WEAK IMPULSE TO DROP THIS WAY TO HELP IN CONVECTION DURING AFTERNOON HEATING. WILL FOLLOW AVERAGE GFS ENSEMBLE MEMBERS FOR NOW AND LEAVE SLIGHT CHANCE OF PCPN OVER ERN AND SRN ZONES FOR WED. GENERALLY FOLLOWED MOS TEMPERATURES THROUGH THE EXTENDED...THE EXCEPTION ONCE AGAIN BEING AFTERNOON HIGHS WHEN MOS APPEARS TO BE HITTING MID 90S A BIT TOO FAST AND WIDESPREAD. LEFT MID 90S FOR MONDAY AND TUESDAY WHEN MODEL CONSENSUS IS FOR STRONGEST RIDGING. WILL SEE ANOTHER DAY OF MID 90S FOR WEDNESDAY IF THE EURO PANS OUT AND THE GFS SOLUTION OF SHIFTING THE RIDGE CENTER DOES NOT WORK OUT. && .AVIATION...UPDATED...WITH MUCH OF THE REGION COVERED IN CIRRUS...VFR CONDITIONS ARE BEING OBSERVED AT ALL SITES THIS MORNING. A BOUNDARY WILL SINK SOUTH BUT REMAIN NORTH OF THE HIGHWAY 82 CORRIDOR TODAY. THIS BOUNDARY SHOULD BECOME THE FOCUS OF SOME ISOLATED TO SCATTERED CONVECTION WHICH WILL LEAD TO A BRIEF PERIOD OR TWO OF MVFR TO IFR CONDITIONS AT SITES WHERE THIS CONVECTION IS OBSERVED FOR THIS AFTERNOON AND EVENING. SOME LOCALIZED MVFR VISIBILITIES AS A RESULT OF PATCHY FOG AND MVFR CEILINGS DUE TO SOME SCATTERED CEILINGS BELOW 3000 FEET WILL BE POSSIBLE SATURDAY MORNING. THOSE CEILINGS WILL QUICKLY GO TO VFR BY 14Z SATURDAY. ISOLATED CONVECTION WILL BE POSSIBLE ACROSS THE NORTH FOR SATURDAY./17/ && .PRELIMINARY POINT TEMPS/POPS...
