The episode as NWS JAN wrote it up.
Warm and humid conditions, common during August in Mississippi, led to the development of a few severe thunderstorms during the afternoon hours of August 6th. Wind damage and some hail occurred as a result of these storms.
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 Jackson, MS wrote its last area forecast discussion before the first event at Aug 6, 9:44 AM CST, 4 hours 31 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON MS 1044 AM CDT MON AUG 6 2012 .UPDATE...LOOK FOR SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS TO DEVELOP THIS AFTERNOON AS WE REMAIN IN A WARM AND HUMID AIRMASS(PW VALUES GREATER THAN 2 INCHES). AN ISOLATED STRONG TO SEVERE STORM WITH WIND POTENTIAL CANNOT BE RULED OUT GIVEN ADDITIONAL BUT WEAK FRONTAL FORCING. TEMPERATURES THIS AFTERNOON WILL ONCE AGAIN TOP OUT IN THE LOW TO MID 90S. THE ONLY CHANGES TO THE FORECAST FOR THIS UPDATE WERE TO SLIGHTLY INCREASE POPS THIS AM ACROSS THE EXTREME NE AND TO THE HOURLY TEMPS. /27/ && .AVIATION...THE EARLY MORNING FOG THAT DEVELOPED HAS DISSIPATED AND VFR CONDITIONS WERE BEING REPORTED AT ALL TAF SITES AT 14Z. VFR CONDITIONS WILL PREVAIL TODAY BUT SCATTERED COVERAGE OF TSRA IS EXPECTED AFTER 18Z. THE EXCEPTION IS AT GTR WHERE TSTMS WERE NOTED ON RADAR JUST TO THE NORTH THAT WILL COME IN VCTY BY 16Z. CONVECTION SHOULD CONTINUE THROUGH 01-03Z WITH SOME POTENTIAL FOR LINGERING SHOWERS OVERNIGHT ALONG THE HIGHWAY 84 CORRIDOR. SOME DRIER AIR MAY MOVE INTO THE DELTA BY 12Z TUESDAY BUT OTHERWISE ANOTHER NIGHT OF MVFR VIS RESTRICTIONS LOOKS POSSIBLE AFTER 06Z TUESDAY THROUGH ABOUT 14Z TUESDAY. 22/28 && .PREV DISCUSSION... /ISSUED 405 AM CDT MON AUG 6 2012/ .SHORT TERM...TODAY THROUGH TUESDAY NIGHT...ANOTHER WARM NIGHT ONGOING ACROSS THE ARKLAMISS. AREA RADARS SHOW A LONE STORM ACROSS NORTHERN MISSISSIPPI THAT HAS BEEN HOLDING ITS OWN FOR SEVERAL HOURS...BUT ADDITIONAL SHOWERS ARE STARTING TO DEVELOP AS WELL IN ASSOCIATION WITH A WEAK FRONTAL BOUNDARY THAT IS CURRENTLY LOCATED ACROSS WESTERN TENNESSEE AND CENTRAL ARKANSAS. MUCH OF THE SOUTH AHEAD OF THE FRONT REMAINS VERY WARM AND MOIST WITH TEMPERATURES IN THE MID AND UPPER 70S(OR IN THE 80S STILL IN A FEW PLACES) AND DEWPOINTS IN THE MID 70S. BEHIND THE FRONT...DEWPOINTS HAVE DROPPED INTO THE MID TO LOWER 60S AND FURTHER TO THE NORTH THE TEMPERATURES HAVE ALSO DROPPED INTO THE 60S...WITH LOCATIONS ACROSS WISCONSIN BEING IN THE 50S! UNFORTUNATELY FOR US...WE WONT BE SEEING THOSE TEMPERATURES ANY TIME SOON AND DRIER AIR WILL EVEN BE HARD FOR SOME TO FIND WITH THIS FRONTAL PASSAGE. THE STUBBORN SUBTROPICAL RIDGE WILL RETREAT BACK WEST TODAY...ALLOWING FOR THE WEAK FRONT TO DROP CLOSE TO AND EVEN INTO THE REGION TODAY. AHEAD OF IT...SHOWERS AND THUNDERSTORMS WILL LIKELY DEVELOP IN THE WARM...MOIST(PW VALUES GREATER THAN 2 INCHES) AIRMASS. MOST HI-RES MODELS DEPICT THUNDERSTORMS WAITING TIL AFTER 18Z OR LATER TO DEVELOP AND THIS SHOULD GIVE THE AREA PLENTY OF TIME TO WARM UP INTO THE LOWER AND MID 90S. THE GREATEST CHANCES FOR RAIN LOOKS TO BE ALONG AND SOUTH OF I-20. AS FOR SEVERE CHANCES...THIS LOOKS ISOLATED. WHILE THE AREA WILL BE WARM AND THERE IS A MOIST AIRMASS IN PLACE...VERTICAL TOTALS ARE AROUND 25-26C...AND WIND SHEAR AND UPPER LEVEL FLOW IS VERY WEAK WHICH SUGGESTS ORGANIZED STORMS ARE LESS LIKELY. THAT BEING SAID...AN ISOLATED STRONG TO SEVERE PULSE STORM WITH WIND POTENTIAL CANNOT BE COMPLETELY RULED OUT GIVEN ADDITIONAL(ALBEIT WEAK) FRONTAL FORCING AND THE WARM/MOIST AIRMASS. WILL INCLUDE A SMALL MENTION IN THE HWO. THE WEAK FRONT WILL NOT MAKE IT THROUGH THE CWA AND THE REGION WILL REMAIN UNDER GENERAL TROUGHING THROUGH THE REST OF THE SHORT TERM. THIS WILL HELP TO GENERATE MAINLY AFTERNOON SHOWERS AND THUNDERSTORMS ACROSS MAINLY THE SOUTHEASTERN HALF OF THE CWA. WHILE MOST OF THE STORMS WILL BE DIURNALLY DRIVEN...THERE COULD STILL BE SOME LINGERING OVERNIGHT...MOSTLY FOR THE FAR SOUTHERN AREAS. DRIER AIR WILL MOVE INTO THE DELTA EARLY TUESDAY AS PW VALUES DROP TO AROUND 1 INCH OR LESS BY 00Z WEDNESDAY. THIS WILL PUSH THE 2 INCH PW AIR TO AROUND THE PINE BELT REGION. TEMPERATURES DURING THE TIME PERIOD WILL BE MORE SEASONAL IN THE LOWER TO MID 90S. OVERNIGHT LOWS WILL DROP INTO THE LOWER TO MID 70S...AND WILL BE HIGHLY DEPENDENT ON THE INVASION OF SOME DRIER AIR AS WELL AS THE EFFECTS OF DAYTIME THUNDERSTORM ACTIVITY. /28/ .LONG TERM...WEDNESDAY THROUGH MONDAY...LOOKS LIKE THE MED RANGE/LONG TERM WILL BE DOMINATED BY AN AMPLIFIED PATTERN WITH A STOUT RIDGE AXIS TO OUR WEST AND AN EASTERN CONUS TROUGH. THIS WILL KEEP OUR REGION UNDER A NW FLOW TYPE PATTERN WHICH TYPICALLY OFFERS TRICKY TIMING ISSUES WITH ANY PRECIP POTENTIAL AS FAST MOVING S/WV'S DIVE SE. OVERALL...GLOBAL MODELS AGREE WITH THE PATTERN...BUT DIFFER SLIGHTLY ON THE TIMING OF THE MAIN S/WV'S WHICH WILL DRIVE THE GREATEST STORM POTENTIAL. AT THIS TIME...THE PERIOD DOES NOT LOOK WET...BUT SOME POTENTIAL WILL EXIST FOR RAIN WITH THE MAJORITY OCCURRING WITH THE PASSAGE OF THE MAIN TROUGH AXIS. OVERALL...POPS FOR THE WED-SAT PERIOD WERE LOWERED FOR THE MOST PART...BUT SOME AREAS WERE LEFT ALONG WITH A PERIOD OR TWO MATCHING THE LATEST GFS GUIDANCE. THERE ARE A FEW SPECIFICS THAT MODELS DO AGREE ON...THE FIRST IS SOME DRIER MID LEVEL AIR ACROSS THE NW HALF FOR WED/THU. DUE TO THIS...POPS WERE LOWERED ACROSS THAT AREA. THE MAIN TIMING ISSUES ARE FOR THU NGT/FRI. POPS WERE LEFT ALONE THU NGT. FOR FRI...POPS WERE LOWERED ACROSS THE NW TO FOLLOW MORE WITH THE EURO/GFS ENSEMBLE. SAT LOOKS DRY AS MODELS SHOW A PATCH OF DRIER AIR IN PLACE IN THE WAKE OF A S/WV AND PRESENCE OF A WEAK/STALLING SFC FRONT. BY SUN/MON...A MORE COMPLICATED SETUP LOOKS TO TAKE SHAPE WITH THE PRESENCE OF THE STALLED BOUNDARY AND LINGERING NW FLOW. AS FOR TEMPS...GUID DIDN'T SEEM TOO BAD AND WAS GENERALLY FOLLOWED. HOWEVER...HIGH TEMPS WERE TWEAKED UPWARD FOR THE WED-FRI DAY PERIODS. REASONING IS BASED ON THE AREA BEING IN THE PRE-FRONTAL ZONE WHERE AN INCREASING LOW LEVEL THERMAL AXIS LOOKS TO SETUP. ADDITIONALLY...ENSEMBLE MOS SUPPORTS WARMER READINGS AS WELL. /CME/ && .PRELIMINARY POINT TEMPS/POPS...
