The episode as NWS CHS wrote it up.
A mid and upper level ridge axis weakened as it shifted south during the early afternoon hours. Strong surface heating resulted in CAPE values around 5000 J/kg over the region. As the seabreeze began to shift inland a few strong thunderstorms developed. A nearly stationary frontal boundary became the focus of severe thunderstorms over the Midlands during the mid afternoon. As this frontal boundary shifted southward a line of severe thunderstorms swept through portions of southern South Carolina and southeast Georgia.
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 Charleston, SC wrote its last area forecast discussion before the first event at Jul 27, 3:23 PM EST, 3 hours 21 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
423 PM EDT TUE JUL 27 2010
.SYNOPSIS...
A TROUGH OF LOW PRESSURE WILL LINGER ACROSS THE AREA THROUGH
WEDNESDAY...BEFORE DISSIPATING ON THURSDAY. A WEAKENING COLD
FRONT WILL MOVE INTO THE REGION FRIDAY...BEFORE STALLING OUT
AND DISSIPATING INTO EARLY NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
WATER VAPOR IMAGERY CONTINUES TO SHOW THE MID AND UPPER LEVEL
RIDGE AXIS SHIFTING FARTHER SOUTH WHILE WEAKENING THIS AFTERNOON.
AT THE SURFACE...THE NEARLY STATIONARY FRONTAL BOUNDARY IS JUST TO
THE NORTH OF THE AREA...BUT COULD BE DRIVEN SOUTHWARD A BIT DURING
THE EVENING HOURS.
THE LOW LEVEL ONSHORE FLOW ALLOWED FOR A FAIRLY QUICK INLAND
PROGRESSION OF THE SEA BREEZE THIS AFTERNOON ACROSS PORTIONS OF
SOUTH COASTAL SOUTH CAROLINA...WITH THE INLAND PUSH OF THE
BOUNDARY AIDED BY OUTFLOW FROM EARLIER CONVECTION. THIS HAS
GENERALLY CAUSED TEMPERATURES TO FALL ACROSS MUCH OF THE
CHARLESTON TRI-COUNTY AREA...THUS PROMPTING THE CANCELLATION OF
THE HEAT ADVISORY FOR CHARLESTON AND BERKELEY COUNTIES.
ELSEWHERE...TEMPERATURES WARMED SIGNIFICANTLY THIS AFTERNOON...
WITH HIGHS IN THE MID TO UPPER 90S IN MANY LOCATIONS...WITH EVEN
TRIPLE DIGIT READINGS IN A FEW PLACES ACROSS SOUTHEAST GEORGIA. AS
A RESULT...THE HEAT ADVISORY WILL REMAIN IN EFFECT UNTIL 8 PM FOR
THESE AREAS.
CONVECTION IS EXPECTED TO INCREASE IN COVERAGE LATE THIS AFTERNOON
INTO EARLY THIS EVENING...BECOMING NUMEROUS TO POSSIBLY EVEN
WIDESPREAD ACROSS PORTIONS OF THE AREA AS NUMEROUS
BOUNDARIES...INCLUDING THE SEA BREEZE...INTERACT. THE ATMOSPHERE
REMAINS RATHER UNSTABLE ACROSS MOST OF SOUTHERN SOUTH CAROLINA AND
SOUTHEAST GEORGIA...WITH CAPE VALUES ANYWHERE FROM 3500-5000 J/KG
AND DOWNDRAFT CAPE VALUES OF 1000-1400 J/KG. AS A RESULT...THE
POTENTIAL IS THERE FOR A FEW THUNDERSTORMS TO BECOME
SEVERE...CAPABLE OF PRODUCING DAMAGING WINDS. AFTER COORDINATION
WITH SPC...IT HAS BEEN DETERMINED THAT THE COVERAGE OF SEVERE
STORMS IS NOT EXPECTED TO BE GREAT ENOUGH TO WARRANT A SEVERE
THUNDERSTORM WATCH AT THIS TIME. IT SHOULD ALSO BE NOTED...THAT
ALL THUNDERSTORMS THROUGH THIS EVENING MAY CONTAIN FREQUENT TO
EXCESSIVE CLOUD-TO-GROUND LIGHTNING AND LOCALLY HEAVY RAINFALL.
THE COVERAGE OF SHOWERS AND THUNDERSTORMS WILL DIMINISH
SIGNIFICANTLY LATE THIS EVENING AND OVERNIGHT...ALTHOUGH WILL
MAINTAIN AT LEAST A SLIGHT CHANCE FOR PRECIPITATION IN THE
FORECAST.
PATCHY FOG MAY DEVELOP LATER TONIGHT ACROSS THE AREA...ESPECIALLY
IN THOSE LOCATIONS THAT RECEIVED RAINFALL...DUE TO THE MOIST LOW
LEVEL CONDITIONS AND LIGHT WINDS IN PLACE.
LOW TEMPERATURES WILL BE HIGHLY DEPENDENT ON HOW MUCH RAIN-COOLED
AIR DEVELOPS AS A RESULT OF LATE AFTERNOON AND EVENING CONVECTION.
THE FORECAST WILL SHOW LOWS GENERALLY IN THE MID TO UPPER 70S
ACROSS THE AREA.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
MODEL GUIDANCE IS IN GOOD
AGREEMENT SHOWING THE SLOW BREAKDOWN OF THE UPPER LEVEL HIGH
PRESSURE...MAINLY AFTER WEDNESDAY. MEANWHILE...WEAK SURFACE
TROUGHING WILL REMAIN IN PLACE ACROSS THE AREA THROUGH THURSDAY
BEFORE A WEAK COLD FRONT MOVES INTO THE AREA FRIDAY. PLENTY OF DEEP
MOISTURE AND INSTABILITY...ALONG WITH THE WEAKENING/DISSIPATING
STATIONARY FRONT AND THE SEA BREEZE...WILL RESULT IN SCATTERED
SHOWER AND THUNDERSTORM DEVELOPMENT ACROSS THE REGION WEDNESDAY.
THUS...WILL CARRY MID/HIGH CHANCE POPS. MODEL SOLUTIONS THEN SHOW
UPPER LEVEL TROUGHING BEGINNING TO AMPLIFY OVER THE EASTERN THIRD OF
THE UNITED STATES WEDNESDAY NIGHT THROUGH FRIDAY. AS THIS HAPPENS
THE DEEPEST MOISTURE WILL SLOWLY SHIFT OFFSHORE...SO EXPECT A
REDUCTION IN SHOWER AND THUNDERSTORM COVERAGE ACROSS THE AREA
THURSDAY AND FRIDAY.
HIGH TEMPERATURES ARE EXPECTED TO RANGE FROM THE MID TO UPPER 90S
THROUGH THE PERIOD AWAY FROM THE BEACHES...WITH LOWS IN THE MID TO
UPPER 70S. CONDITIONS MAY NOT REACH HEAT ADVISORY THRESHOLDS FOR
ADEQUATE DURATION TO WARRANT A HEAT ADVISORY ACROSS ALL OR PORTIONS
OF THE FORECAST AREA WEDNESDAY DUE TO CONVECTION. HEAT INDICES ARE
EXPECTED TO TOP 105 BOTH THURSDAY AND FRIDAY...AND WITH THE COVERAGE
OF CONVECTION LIKELY LOWER THAN WEDNESDAY...HEAT ADVISORIES WILL
LIKELY BE NEEDED EACH AFTERNOON.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
MODEL SOLUTIONS REMAIN IN FAIRLY GOOD AGREEMENT PUSHING A WEAKENING
FRONTAL BOUNDARY SOUTHWARD INTO THE AREA OVER THE WEEKEND...WITH THE
BOUNDARY THEN SLOWLY DISSIPATING THROUGH EARLY NEXT WEEK. WILL
GENERALLY CARRY SLIGHT CHANCE/LOW CHANCE POPS THROUGH THE
PERIOD...FOR PRIMARILY AFTERNOON/EVENING CONVECTION. EXPECT HIGHS
GENERALLY IN THE LOW TO MID 90S AND LOWS IN THE MID 70S THROUGH THE
LONG TERM PERIOD. ADDITIONAL HEAT ADVISORIES ARE POSSIBLE FOR ALL OR
PORTIONS OF THE AREA.
&&
.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
THE SEABREEZE IS BEGINNING ITS PUSH INLAND AND HAS ALREADY MOVED
THROUGH CHS. MOISTURE CONVERGENCE ALONG THE SEABREEZE IS LEADING
TO SHOWER AND THUNDERSTORM DEVELOPMENT. STORMS LOOK MOST LIKELY TO IMPACT
CHS SOMETIME BETWEEN 18Z AND 20Z THIS AFTERNOON BEFORE THE
SEABREEZE MOVES FURTHER INLAND WITH MVFR OR LOWER CONDITIONS
POSSIBLE. STORMS WILL LIKELY BE DELAYED AN HOUR OR SO AT SAV
BETWEEN 19Z AND 21Z. STRONG TO SEVERE STORMS WILL BE POSSIBLE
TODAY AND AMENDMENTS WILL BE NEEDED.
ADDITIONAL STORMS WILL BE POSSIBLE THROUGH THE AFTERNOON AND INTO
THE OVERNIGHT AS A COMPLEX OF STORMS DEVELOPS FURTHER INLAND AND
MOVES EAST. STORMS WILL LIKELY WEAKEN AS THEY APPROACH THE
TERMINALS TONIGHT BUT WILL STILL CONTINUE CB FOR THE POSSIBILITY.
WINDS WILL BE LIGHT AND VARIABLE THROUGH THE OVERNIGHT WITH A
LITTLE HAZE AND FOG DEVELOPING TOWARDS DAYBREAK...MOST LIKELY NEAR
CHS WHICH IS CLOSER TO THE FRONT WHICH IS WASHING OUT IN CENTRAL
SOUTH CAROLINA.
EXTENDED AVIATION OUTLOOK...MAINLY VFR CONDITIONS ARE EXPECTED
THROUGH THE PERIOD...ALTHOUGH ISOLATED OR SCATTERED
AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS MAY BRIEFLY REDUCE
CIGS/VSBYS EACH DAY. THE BEST CHANCE FOR REDUCED CIGS/VSBYS
APPEARS TO BE ON WED...WITH MORE ISOLATED ACTIVITY THU THROUGH
SUN.
&&
.MARINE...
A FRONT WILL REMAIN STALLED JUST NORTH OF THE WATERS TONIGHT...RESULTING
IN A RATHER LIGHT SURFACE PRESSURE GRADIENT. WIND DIRECTIONS COULD
BE SOMEWHAT ERRATIC...AS OUTFLOW FROM STORMS SPREAD ACROSS THE
WATERS. WIND SPEEDS SHOULD REMAIN 10 KT OR LESS THROUGH THE
NIGHT...WITH SEAS NO GREATER THAN 3 FT.
WEDNESDAY THROUGH SATURDAY...A WEAK PRESSURE PATTERN WILL LEAD TO
RATHER BENIGN MARINE CONDITIONS THROUGH THU BEFORE WINDS PICK UP A
BIT THU NIGHT INTO FRI AS A WEAK COLD FRONT PUSHES TOWARD THE AREA.
THE FRONT WILL THEN STALL OUT OVER OR NEAR THE AREA INTO THE WEEKEND
WITH A RETURN OF RATHER BENIGN CONDITIONS.
