The episode as NWS JAN wrote it up.
A warm and moist airmass over the region, coupled with a weak upper low to the east of the forecast area, triggered a few severe thunderstorms both afternoons. The storms primarily generated gusty winds although some hail up to 1 inch in diameter was found.

NWS Jackson, MS wrote its last area forecast discussion before the first event at May 24, 3:59 PM CST, 54 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON MS 459 PM CDT MON MAY 24 2010 .UPDATE... A LINE OF SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS EXTENDS FROM EASTERN ARKANSAS EASTWARD INTO NORTHERN MISSISSIPPI. A WELL- DEFINED OUTFLOW BOUNDARY HAS PUSHED SOUTH OF THE AFOREMENTIONED CONVECTION AND IS PRESENTLY ENTERING THE NORTHERN CWA WEST OF INTERSTATE 55. CONVERGENCE ALONG THIS BOUNDARY WILL LIKELY BE RESPONSIBLE FOR ADDITIONAL CONVECTIVE INITIATION ACROSS THE NORTHWEST DELTA REGION...AND THE FORECAST HAS BEEN UPDATED TO RAISE POPS IN THIS REGION FOR THE REMAINDER OF THIS AFTERNOON. POPS WERE ALSO RAISED ACROSS SOUTHWESTERN MISSISSIPPI FOR THE REMAINDER OF THIS AFTERNOON...WHERE SCATTERED SHOWERS AND STORMS ARE OCCURRING. /COHEN/ && .PREV DISCUSSION... /ISSUED 355 PM CDT MON MAY 24 2010/ SHORT TERM...A COUPLE OF WEAK IMPULSES WILL MAINTAIN THE RISK OF ISOLATED STRONG TO SEVERE STORMS THIS EVENING. THE FIRST IS DROPPING INTO NRN MS THIS AFTERNOON WHILE A SECOND SYSTEM IS PIVOTING INTO SWRN ZONES. WITH CAPE VALUES CLOSE TO 2000 AND VERTICAL TOTALS IN THE UPPER 20S THE AIR MASS IS MORE THAN UNSTABLE ENOUGH TO SUPPORT STRONG TO SEVERE CONVECTION. DEEPER MOISTURE REMAINS IN PLACE ACROSS MUCH OF THE FORECAST AREA BUT A FETCH OF DRIER AIR FROM THE EAST HAS RESULTED IN LOWER DEWPOINTS OVER ERN ZONES. SURFACE DEWPOINTS HAVE MIXED TO 61 AT MEI AND BACK EAST INTO AL BUT REMAIN IN THE UPPER 60S TO NEAR 70 RANGE ALONG THE I-55 CORRIDOR AND WWD. WILL KEEP ISOLATED THUNDERSTORMS INTO THE EVENING HOURS DUE TO REDEVELOPMENT OF CONVECTION ALONG OUTFLOW BOUNDARIES WITH A MENTION OF ISOLATED SEVERE IN THE HWO FOR CENTRAL AND WRN AREAS. UPPER RIDGING WILL CONTINUE TO GIVE WAY TO BROAD UPPER TROUGHING TO OUR EAST. THIS WILL MEAN A CONTINUED CHANCE OF AT LEAST AFTERNOON AND EVENING CONVECTION FOR MOST OF THE AREA WELL INTO THE WORK WEEK. TIMING OF WAVES IN THE RESULTING NLY FLOW OVER OUR AREA WILL BE A SIGNIFICANT FACTOR IN DETERMINING THE OCCURRENCES OF BETTER CONVECTION COVERAGE...MAKING THE EXACT PLACEMENT OF THE BEST RAIN CHANCES EACH PERIOD DIFFICULT TO PIN DOWN. PRECIP WATER WILL REMAIN WELL ABOVE 1.5 INCHES THROUGH THE SHORT TERM OVER WRN ZONES. THE FETCH OF DRIER AIR OVER ERN ZONES IS FORECAST TO CONTINUE TUESDAY ALTHOUGH IT WILL WEAKEN WITH TIME. WILL KEEP LOWEST POPS ERN ZONES FOR TOMORROW BUT MAINTAIN ISOLATED THUNDERSTORMS ACROSS THE ENTIRE REGION FOR THE AFTERNOON AND EVENING HOURS. INCREASED TUESDAY POPS SLIGHTLY OVER MAV SINCE WE REMAIN IN THE TRACK FOR UPPER IMPULSES IN AN UNSTABLE AND WARM AIR MASS. MAV AFTERNOON HIGHS LOOKED A BIT TOO COOL FOR TOMORROW AND WERE HOISTED A COUPLE OF DEGREES HIGHER. BETTER SYNOPTIC FORCING IS SUGGESTED BY WEDNESDAY WHEN A LOBE OF THE UPPER TROUGH PIVOTS IN FROM THE N. GENERAL ASCENT WITH THIS FEATURE DOES NOT LOOK IMPRESSIVE BUT AS CYCLONIC FLOW DEVELOPS AT THE 850 MB LEVEL IN RESPONSE TO A DEVELOPING WAVE TO THE EAST THIS SHOULD PROVIDE AN EXTRA PUSH FOR AFTERNOON TSTM DEVELOPMENT. WE WILL MAINTAIN A MENTION OF ISOLATED STRONG TO SEVERE THUNDERSTORMS IN THE HWO WELL INTO THE WORK WEEK. LONG TERM...A CLOSED UPPER LOW OFF THE SOUTH ATLANTIC COAST WILL PROVIDE SOME MOISTURE CONVERGENCE FOR THE REGION WITH ML CAPES OF AROUND 2000 AND PRECIPITABLE WATER AROUND 1.8 INCHES WITH LOW CIN. THIS WILL HELP TO PROMOTE DIURNAL CONVECTION THURSDAY INTO FRIDAY. IMPULSES WILL COME DOWN THE REGION IN NORTHERLY FLOW. THIS WILL COME DOWN IN THE FORM OF WEAK BOUNDARIES...WHICH WILL PROVIDE SOME LIFT FOR DIURNAL CONVECTION TO OCCUR. AS WE GO INTO THE WEEKEND THE UPPER RIDGE AXIS WILL SPREAD INTO THE REGION FROM THE WEST. THIS WILL LIMIT OUR CHANCES OF DIURNAL CONVECTION AS WE GET SOME HEIGHT RISES COMING INTO THE REGION. PRECIPITABLE WATER WILL DIP DOWN TO AROUND ONE INCH FOR THE WEEKEND. THE UPPER TROUGH WILL EVENTUALLY BRING A BACK DOOR FRONT TOWARD THE REGION AS WE GO INTO THE REGION...BUT WILL IT WILL BECOME STATIONARY NORTHEAST OF THE REGION WITH THE UPPER RIDGE BECOMING MORE ESTABLISHED. SO FOR THIS WEEKEND DIURNAL CONVECTION SHOULD BECOME MORE ISOLATED. THIS WAS AGREED UPON BY THE ENSEMBLES WHICH SHOWED THE REGION UNDER THE INFLUENCE OF THE UPPER TROUGH UNTIL THE WEEKEND. THE EURO SEEMS TO BE AN OUTLIER IN WHICH AN IMPULSE OVER THE WEEKEND DEVELOPS A CLOSED UPPER LOW OVER THE REGION. IT HAS THIS FEATURE MOVING EAST OF THE REGION BY MONDAY EVENING. SO IT KEEPS A BETTER CHANCE OF RAIN OVER THE REGION. SO THIS SOLUTION WAS DISCARDED. AS WE GO INTO MONDAY FLAT UPPER RIDGING WILL DEVELOP OVER THE REGION... A WEAK SHORT WAVE WILL MOVE INTO THE REGION BY MONDAY EVENING...AS PRECIPITABLE WATER INCREASES FROM THE NORTH TO AROUND 1.3 INCHES. AS FAR AS POPS ARE CONCERN MADE SLIGHTLY HIGHER ADJUSTMENTS TO MEX POPS THROUGH FRIDAY. THEN WENT WITH MEX LOW POPS FOR SATURDAY AND SUNDAY. AS FAR AS TEMPS ARE CONCERN MADE SLIGHT ADJUSTMENTS TO MEX...MOS AND MEN GUIDANCE. GOING GENERALLY WITH LOWS FROM MAINLY THE MIDDLE 60S TO THE LOWER 70S AS WELL AS HIGHS FROM THE UPPER 80S TO LOWER 90S. THERE WERE SOME MIDDLE 80S MODEL HIGHS IN WHICH I WAS NOT VERY CONFIDENT WITH./17/ && .AVIATION... ISO/SCT TSRA ARE POSSIBLE THIS AFTERNOON AND EARLY EVENING...MAINLY AFFECTING GWO/GLH AND JAN BRINGING WITH IT OCCASIONAL MVFR/IFR TO THOSE AFFECTED.
