The episode as NWS JAN wrote it up.
An extremely warm and moist airmass was in place over the region on the morning of August 15th. Abundant sunshine during the morning hours led to the development of extremely high atmospheric instability by early afternoon. This environment led to numerous severe thunderstorms throughout the day, continuing into the evening hours. Numerous damaging wind reports were received, including several reports of damage caused by a strong outflow boundary that surged south across the forecast area.
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 15, 1:16 PM CST, 44 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
216 PM CDT SUN AUG 15 2010
..EXCESSIVE HEAT OCCURRING TODAY...
...SEVERE STORMS POSSIBLE TODAY...
.UPDATE...QUICK UPDATE HERE TO MENTION THAT WE HAVE EXPANDED THE HEAT
ADV...EFFECTIVE NOW...FOR THE SE PORTION OF THE CWA. TEMPS AND HI'S
HAVE BEEN EXCESSIVE ACROSS THE ENTIRE CWA. THE TIME DURATION WILL
FALL SHORT FOR A WARNING...SO HAVE GONE WITH A HEAT ADV FOR ALL AREAS
UNTIL 7 PM MON. ALSO...THERE IS A EXCESSIVE HEAT WARN STILL IN EFFECT
UNTIL 7 PM TODAY FOR PORTIONS OF THE NW. THAT FITS WELL AND WILL LET
RIDE AS IT TRANSITIONS TO A PLAIN HEAT ADV FOR TONIGHT AND MON. /CME/
&&
.PREV DISCUSSION... /ISSUED 1159 AM CDT SUN AUG 15 2010/
UPDATE...THIS UPDATE IS TO STRESS EARLIER THINKING ON CONVECTIVE
POTENTIAL AND RISK OF SVR STORMS. INTENSE INSOLATION HAS BEEN
OCCURRING THIS MORNING AND ALL AREAS ARE HEATING UP VERY FAST. AT THE
SAME TIME...CU DEVELOPMENT HAS NOT STARTED YET...EVEN IN THE FACE OF
SFC DEWPTS HOLDING IN THE UPPER 70S. IT APPEARS LIKELY THAT SBCAPE
COULD REACH 5000 J/KG BETWEEN NOW AND 2 PM AS CONVECTION INITIATES.
THIS LATE CU DEVELOPMENT IS TYPICALLY A SIGN THAT WHEN CU
FORMS...THEY WILL GROW RAPIDLY INTO CB DUE TO VIGOROUS
UPDRAFTS...ESPECIALLY IN THE CURRENT ENVIRONMENT. CONFIDENCE IS NOW
HIGHER ON THE POTENTIAL FOR SVR STORMS FIRST ACROSS THE S/SE AREAS
THEN IN THE N LATER THIS AFTN/EVE. AS A RESULT...HAVE PLAYED UP THE
RISK FOR SVR STORMS IN THE HWO. SEE DISCUSSIONS BELOW FOR MORE DETAIL.
ADDITIONALLY...A SVR TSM WATCH BOX IS POSSIBLE FOR THE AFTERNOON HRS.
/CME/
PREV DISCUSSION... /ISSUED 1032 AM CDT SUN AUG 15 2010/
DISCUSSION...THE HAZARD DISCUSSION BELOW WILL COVER THE LATEST
THINKING WRT STRONG/SVR STORMS FOR THE REST OF TODAY. OUTSIDE
THAT...THE MAIN ELEMENTS OF THE CURRENT FORECAST ARE ON TRACK AND NO
MAJOR ADJ WERE NEEDED. THE GREATEST COVERAGE OF STORMS STILL LOOKS TO
BE ACROSS THE S/SE PORTIONS FROM NOON TO 5 PM OR SO WITH MORE OF A
CONDITIONAL RISK FOR CONVECTION ACROSS THE N HALF FROM LATE AFTERNOON
INTO EVENING.
AS FOR THE HEAT...CONDITIONS REMAIN VERY OPPRESSIVE AND CURRENT HEAT
PRODUCTS COVER THINGS WELL. THE MOST EXTREME CONDITIONS WILL EXIST
ACROSS THE NW/W-CENTRAL AND N PORTIONS TODAY WHERE SFC TEMPS WILL
PEAK BETWEEN 100-105. ADD THAT TO HIGH HUMIDITY AND HI'S WILL PEAK
BETWEEN 112-118 DEGREES. THE EXCESSIVE HEAT WARNING AREA LOOKS GOOD
AS THAT IS WHERE THE HIGHEST CONDITIONS LOOK TO EXIST AND THE TIME
DURATION HAS BEEN MET. LOCATIONS JUST OUTSIDE THE WARNING...WILL
LIKELY SEE HI'S EXCEED 110...BUT THEY WILL LIKELY FALL SHORT OF THE
TIME DURATION. WITH THAT...A HEAT ADV IS IN EFFECT TO COVER THE REST
OF THE AREA. THE ONLY EXCEPTION IS A GROUP OF COUNTIES ACROSS THE SE.
HERE...STORMS/CLOUDS SHOULD LIMIT THE HEAT...BUT THERE WILL LIKELY BE
A BRIEF PERIOD WHERE HI'S REACH 105. /CME/
CONVECTIVE IMPACTS...
THE POTENTIAL WILL EXIST FOR STRONG TO SEVERE THUNDERSTORMS THIS
AFTERNOON AND EVENING.
FOR LOCATIONS SOUTH OF A LINE FROM MACON TO JACKSON TO
WINNSBORO...TEMPERATURES THIS AFTERNOON ARE EXPECTED TO TOP OUT IN
THE MID AND UPPER 90S...WITH SURFACE DEWPOINTS IN THE 74 TO 77
DEGREE RANGE. UPPER AIR DATA FROM 12Z SOUNDINGS AT KJAN AND KLIX
SUGGEST THAT THESE SURFACE CONDITIONS WILL YIELD SBCAPES FROM 4300
TO 4700 J/KG...SUPPORTING VIGOROUS CONVECTIVE UPDRAFTS THIS
AFTERNOON. LITTLE IN THE WAY OF BOUNDARY-LAYER DRYING IS
ANTICIPATED...HOWEVER...AS PLENTIFUL LOW-LEVEL MOISTURE IS EXPECTED
TO PERSIST THROUGH THE DAY...WITH NWP GUIDANCE SOMEWHAT UNDER-
INITIALIZING THE DEGREE OF DEEP-LAYER MOISTURE. IN FACT...
MULTI-MODEL CONSENSUS IS INDICATING AN INCREASE IN MOISTURE
CONVERGENCE ALONG A CONFLUENCE AXIS WEST OF THE CENTER OF THE 850 MB
CYCLONIC CIRCULATION ASSOCIATED WITH THE REMNANTS OF TROPICAL
DEPRESSION FIVE OVER SOUTHERN ALABAMA/GEORGIA. MOISTURE IS FORECAST
TO POOL ALONG THIS AXIS...MAINTAINING THE HIGH DEWPOINTS THROUGH THE
DAY AND PROVIDING A SOURCE OF CONVECTIVE INITIATION. ALREADY...A FEW
SHOWERS HAVE BEGUN DEVELOPING ALONG THIS AXIS ACROSS SOUTHEAST
MISSISSIPPI THIS MORNING. GREATER CONVECTIVE COVERAGE IS EXPECTED TO
HOLD OFF UNTIL THIS AFTERNOON AFTER SURFACE TEMPERATURES WARM CLOSER
TO THE CONVECTIVE TEMPERATURE IN THE ABSENCE OF STRONGER FORCING.
MEANWHILE...A MODEST AMOUNT OF DRY AIR IN THE MID-LEVELS AT THE
EASTERN PERIPHERY OF THE SOUTHERN CONUS RIDGE WILL CONTINUE TO
FILTER SOUTHWARD ACROSS THE REGION. THE COMBINATION OF THIS DRY
AIR...AND VERY STEEP LOW-LEVEL LAPSE RATES...WILL SUPPORT DCAPE
VALUES IN THE 1100 TO 1400 J/KG RANGE THIS AFTERNOON. LOCAL WET
MICROBURST GUIDANCE INDICATES A RISK FOR STRONG TO SEVERE WIND GUSTS
WITH ANY DEEP CONVECTION THAT DEVELOPS. ADDITIONALLY...MEAN 850-700
MB FLOW WILL BE NORTH-TO NORTHEAST AT 15 TO 20 KNOTS...AND WILL
ENHANCE THE WIND POTENTIAL. THE GREATEST POTENTIAL FOR STRONG TO
SEVERE STORMS WILL BE ACROSS SOUTHEAST MISSISSIPPI...CLOSER TO THE
LOW-LEVEL CONFLUENCE AXIS. THE ABSENCE OF MORE SUBSTANTIAL
UPPER-LEVEL FORCING MECHANISMS WILL PRECLUDE A GREATER COVERAGE OF
SEVERE STORMS THIS AFTERNOON. THE GREATEST POTENTIAL FOR SEVERE
STORMS SOUTH OF THE AFOREMENTIONED LINE WILL BE BETWEEN 1 AND 6 PM.
FOR LOCATIONS NORTH OF A LINE FROM MACON TO JACKSON TO
WINNSBORO...SIMILAR THERMODYNAMIC AND KINEMATIC CONDITIONS WILL
EXIST THIS AFTERNOON AND EVENING. HOWEVER...ASCENT WILL BE WEAKER
ACROSS THIS AREA UNTIL A SURFACE BOUNDARY BEGINS TO DROP INTO THE
MID-SOUTH REGION THIS EVENING...CAUSING LOW-LEVEL CONVERGENCE TO
INCREASE. AS A RESULT...THE GREATER POTENTIAL FOR STRONG TO SEVERE
STORMS WILL HOLD OFF UNTIL AFTER 4 PM. LOCAL HIGH-RES WRF GUIDANCE
IS INDICATING MORE ISOLATED CONVECTIVE COVERAGE ACROSS THIS REGION.
HOWEVER...THE CONDITIONAL POTENTIAL FOR SEVERE STORMS WILL BE
ELEVATED IN THIS REGION WITH 850-500 MB TEMPERATURE DIFFERENCES
RISING IN THE 26-27C RANGE AS LOW-LEVEL WARMING IS GREATEST ACROSS
THE NORTH. AS SURFACE TEMPERATURES TOP OUT IN THE 98 TO 105 DEGREE
RANGE...AND DCAPES RISE TO AROUND 1400 J/KG...ANY STORMS WILL BE
VERY EFFICIENT AT PRODUCING STRONG TO SEVERE SURFACE WINDS. THIS
POTENTIAL WILL CONTINUE UNTIL 10 PM AS THE BOUNDARY APPROACHES THE
NORTHERN CWA. /COHEN/
&&
.AVIATION...
SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED THIS
AFTERNOON AND EVENING...MAINLY BETWEEN 15/1700 UTC AND 16/0300 UTC.
THE COVERAGE OF STORMS WILL BE MORE ISOLATED ALONG AND NORTHWEST OF A
LINE FROM KGLH TO KGWO. GIVEN UNCERTAINTY IN THE TIMING AND DURATION
OF THE ACTIVITY AT ANY GIVEN TAF SITE...MENTION OF VCTS IS BEING MADE
IN THE TAFS AT THIS POINT. THE STRONGEST STORMS WILL BE CAPABLE OF
PRODUCING WIND GUSTS TO 50 KT ALONG WITH SMALL HAIL AND VERY HEAVY
RAINFALL. ALSO...MVFR TO IFR CEILINGS/VISIBILITIES ARE EXPECTED TO
ACCOMPANY THE SHOWERS AND THUNDERSTORMS. OUTSIDE OF SHOWERS AND
STORMS...GENERALLY VFR CONDITIONS ARE EXPECTED THROUGH MONDAY
AFTERNOON WITH LIGHT WINDS. HOWEVER...MVFR VISIBILITIES DUE TO PATCHY
FOG WILL BE POSSIBLE ACROSS EAST CENTRAL AND SOUTHEAST MISSISSIPPI
BETWEEN 16/1000 UTC AND 16/1300 UTC. /COHEN/
