The episode as NWS CHS wrote it up.
A warm front slowly lifted north over portions of southeast South Carolina during early morning hours. Deep moisture accompanied the front which helped set up an environment capable of producing heavy rain and flash flooding as showers and thunderstorms trained over the 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 Charleston, SC wrote its last area forecast discussion before the first event at Mar 24, 6:47 AM EST, 1 hour 58 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
747 AM EDT SUN MAR 24 2013
.SYNOPSIS...
A WARM FRONT WILL CONTINUE TO LIFT NORTH INTO THE AREA THIS
MORNING. LOW PRESSURE WILL DEVELOP ALONG THE FRONT AND DEEPEN AS
IT LIFTS NORTHEAST OFF THE SC COAST THIS AFTERNOON. A TRAILING
COLD FRONT WILL THEN MOVE THROUGH TONIGHT...BRINGING WITH IT
STRONG WINDS AND A COLDER AIR MASS. DEEP LOW PRESSURE WILL MOVE
AWAY FROM THE EAST COAST...WITH COOL HIGH PRESSURE TO BUILD FROM
THE WEST AND NW THROUGH THE WEEK.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SQUALL LINE TAKING SHAPE OVER AND SW OF THE FORECAST ZONES THIS
MORNING...AND WILL RACE THROUGH THE AREA BETWEEN NOW AND EARLY
AFTERNOON. SURFACE BASED INSTABILITY STILL LACKING...BUT WE
CONTINUE TO MAINTAIN THE RISK OF ISOLATED SEVERE WEATHER UNTIL IT
CLEARS THE REGION. HEAVY RAINS WILL ALSO CONTINUE TO BE A CONCERN.
THE PATTERN ALOFT INDICATES A STRONG SHORT WAVE DROPPING THROUGH
THE CENTRAL AND SOUTHERN PLAINS THAT WILL CLOSE OFF TODAY...AS IT
TAKES ON A NEGATIVE TILT WHILE IT HEADS TO THE REGION OF TN AND KY
LATE. LOW PRESSURE IN THE LOWER MS VALLEY THIS MORNING WILL
REDEVELOP CLOSER TO THE ATTENDANT FEATURE ALOFT...WHILE AT THE
SAME TIME IT WILL LIFT A WARM FRONT THROUGH MOST OF THE FORECAST
AREA THIS MORNING AND EARLY AFTERNOON. HOWEVER...THE NORTHWARD
PROGRESSION OF THE FRONT WILL BE RESTRICTED SOMEWHAT DUE TO A WAVE
OF LOW PRESSURE FORMING ALONG A TRIPLE POINT OR OCCLUDED
BOUNDARY. THAT WAVE WILL FORM OVER SW GA THIS MORNING...TRACKING
ACROSS THE CENTRAL ZONES BY EARLY AFTERNOON...THEN OFF THE
CHARLESTON COUNTY COAST BY 21Z. THE NORTHWARD PROGRESSION OF THIS
FRONT WILL BE A MAJOR FACTOR IN THE RISK FOR SEVERE WEATHER TODAY.
THERE IS CONSIDERABLE WIND THROUGHOUT THE TROPOSPHERE...WITH THE
REGION TO LIE WITHIN THE LEFT FRONT QUAD OF THE 130 KT OR GREATER
UPPER JET...PLUS WE/LL BE SITUATED WITHIN A 70 KT MID LEVEL JET
AND A 50 KT OR GREATER LOW LEVEL JET DURING THIS MORNING. THE
WARM FRONT...LOCATED JUST SOUTH OF THE ALTAMAHA RIVER EARLY THIS
MORNING SHIFTS NORTH TO ABOUT I-16 IN SE GA BY LATE MORNING...THEN
TO A POSITION FROM ABOUT CHARLESTON COUNTY TO THE CENTRAL SAVANNAH
RIVER AREA EARLY THIS MORNING. IT MAY LIFT A LITTLE FURTHER
NW...BUT THAT LOOKS TO BE ABOUT AS FAR AS IT/S ABLE TO ACHIEVE
BEFORE THE TRIPLE POINT WAVE OF LOW PRESSURE FORMS AND MOVES OVER
THE ATLANTIC. THERE IS CERTAINLY CONSIDERABLE FORCING FOR ASCENT
WITH THE STRONG WIND FIELDS...ASSOCIATED UPPER DIFLUENCE AND
FAVORABLE MID LEVEL LAPSE RATES. AS MORE SURFACE BASED CAPE AND
INSTABILITY DEVELOPS WITHIN THE WARM SECTOR WE WILL START TO SEE
ISOLATED STRONG OR SEVERE T-STORMS DEVELOPING THIS MORNING. WITH
BULK SHEAR IN THE 0-6 KM LAYER SOME 70 KT OR SO AND VORTICITY
GENERATION PARAMETERS GREATER THAN 0.2...PLUS RIGHT TURNING
HODOGRAPHS...THERE APPEARS TO BE A RISK NOT ONLY FOR ISOLATED
SUPERCELLS WITH DAMAGING WINDS/LARGE HAIL...BUT ALSO A POSSIBLE
TORNADO OR TWO. THE WINDOW FOR ANY SEVERE WEATHER LOOKS TO BE
THROUGH ABOUT 16-18Z...MAINLY OVER THE CENTRAL AND SOUTHERN
ZONES...AND COASTAL SC.
WIDESPREAD SHOWERS AND SCATTERED T-STORMS /BOTH SURFACE-BASED AND
ELEVATED/ WILL BE FORECAST FOR THIS MORNING...THEN COVERAGE DROPS
OFF THIS AFTERNOON AS DRY SLOT ATTEMPTS TO MOVE IN WITH DRYING
FROM THE TOP OF THE ATMOSPHERE ON DOWN. PWATS OF 1.5 TO 1.75
INCHES...NEAR OR GREATER THAN THE 99TH PERCENTILE SUGGEST THAT
LOCALLY HEAVY RAINFALL WILL OCCUR.
A LARGE TEMP GRADIENT WILL OCCUR TODAY...MID 60S NORTH OF THE WARM
FRONT AT BEST...TO MID AND UPPER 70S TO IT/S SOUTH. WE COULD EVEN
HIT 80 CLOSE TO THE ALTAMAHA RIVER. SHORELINE AREAS WILL BE
LIMITED BY SW SYNOPTIC FLOW DEVELOPING.
IT/LL ALSO BECOME BREEZY IN MANY AREAS SOUTH OF THE WARM
FRONT...WITH MIXING HEIGHTS TAPPING INTO 30 KT OR SO WITHIN THE
PLANETARY BOUNDARY LAYER.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
TONIGHT...THE CYCLONIC SYSTEM ALOFT WILL DEEPEN AS IT MOVES
THROUGH THE OH/TN VALLEYS. THIS GENERATE DECENT HEIGHT FALLS
LOCALLY...SO UNTIL THE COLD FRONT MOVES THROUGH THERE IS STILL A
SMALL RISK OF SHOWERS EARLY ON...MAINLY NORTH AND NW. THE ATLANTIC
LOW WILL CONTINUE TO INTENSIFY AS IT MOVES NE UP THE COAST...WITH
ITS TRAILING COLD FRONT TO SWEEP QUICKLY THROUGH DURING THE FIRST
PART OF THE NIGHT. THIS WILL ALLOW FOR RAPID CLEARING ND USHER IN
A MUCH COLDER AIR MASS. ISALLOBARIC PRESSURE RISES OF 1-2 MB EVERY
3 HOURS AFTER THE FROPA SUGGEST THAT IT WILL BECOME BREEZY IF NOT
WINDY AT TIMES. PROBABLY NOT ENOUGH FOR A WIND ADVISORY...BUT
30-40 KNOTS WITHIN THE PLANETARY BOUNDARY LAYER WE MIGHT BE CLOSE.
LAKE WINDS...COLD ADVECTION AND THE STEADY PRESSURE RISES AFTER
THE COLD FRONT MOVES THROUGH WILL GENERATE AN INCREASE IN WINDS TO
LAKE WIND ADVISORY CRITERIA BEGINNING AT 3 AM MONDAY.
MONDAY AND MONDAY NIGHT...THE FORECAST AREA WILL FIND ITSELF JUST
SOUTH OF A VERY DEEP AND POTENT UPPER LOW MOVING ACROSS THE CENTRAL
APPALACHIANS AND OFF THE MID ATLANTIC COAST ON MONDAY. THE SURFACE
LOW ASSOCIATED WITH IT WILL BE UNDERGOING AN IMPRESSIVE DEEPENING
TREND AS IT MOVES OVER THE ATLANTIC...SETTING UP A VERY TIGHT
WESTERLY PRESSURE GRADIENT OVER THE FORECAST AREA. THIS TIGHTENING
GRADIENT COMBINED WITH A STRONG LOW LEVEL JET AND DIURNAL MIXING
WILL RESULT IN A WINDY DAY. FREQUENT GUSTS TO 40 MPH ARE EXPECTED
FOR MUCH OF THE AREA AND A WIND ADVISORY WILL LIKELY BE NEEDED FOR
SOME OR ALL OF THE FORECAST AREA. THE OTHER STORY CONCERNS THE
CLIMATOLOGICALLY COOL TEMPERATURES. EXPECT HIGHS TO NOT GET OUT OF
THE UPPER 50S IN MOST AREAS EXCEPT FOR FAR SE GA NEAR THE ALTAMAHA.
THESE TYPES OF TEMPS ARE BETWEEN 10-15 DEGREES BELOW NORMAL FOR LATE
MARCH. OVERNIGHT...WINDS WILL REMAIN ELEVATED AND BREEZY. LOWS WILL
FALL INTO THE LOW TO MID 30S WITH SOME INLAND AREAS FALLING TO NEAR
FREEZING. GIVEN THE AMOUNT OF WIND EXPECTED...FROST LIKELY WILL NOT
BE AN ISSUE BUT AN ADVECTIVE FREEZE IS POSSIBLE IN THESE LOCATIONS.
A FREEZE WATCH MAY EVENTUALLY BE NEEDED.
TUESDAY THROUGH WEDNESDAY...THE OVERALL SETUP WILL NOT CHANGE MUCH
AS HIGH PRESSURE OVER THE CENTRAL CONUS CONTINUES TO SLOWLY BUILD
IN. TUESDAY WILL BE ANOTHER BREEZY DAY...ALBEIT LESS THAN
MONDAY...WITH WESTERLY GUSTS INTO THE 30-35 MPH RANGE POSSIBLE. A
SHARP UPPER TROUGH AND VIGOROUS CHANNELED VORT MAX WILL MOVE THROUGH
IN THE AFTERNOON. SOME MODELS ARE TRYING TO GENERATE VERY LIGHT
PRECIP ASSOCIATED WITH THIS UPPER FEATURE...BUT GIVEN THE DEGREE OF
DRY AIR...IT WILL LIKELY MANIFEST ITSELF AS AN INCREASE IN CLOUDS
TUESDAY AFTERNOON. WEDNESDAY WILL BE LESS BREEZY AS THE HIGH MOVES
CLOSER AND THE GRADIENT RELAXES. TEMPS WILL REMAIN QUITE CHILLY
THOUGH WITH HIGHS PRIMARILY IN THE UPPER 50S...STILL ABOUT 15
DEGREES BELOW CLIMO. POTENTIAL EXISTS FOR SOME FROST/FREEZE ISSUES
TUESDAY NIGHT AS WELL.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
THE AREA WILL REMAIN UNDER THE INFLUENCE OF DEEP NW FLOW ALOFT
ASSOCIATED WITH THE COOL UPPER LEVEL TROUGH NEAR THE NORTHEAST US.
HIGH PRESSURE WILL BE IN CONTROL ACROSS THE REGION INTO THE WEEKEND.
AS THE TROUGH WEAKENS ALOFT AND THE LOW LEVEL FLOW FINALLY TURNS
MORE SOUTHERLY...TEMPS WILL START TO MODERATE BY THE WEEKEND CLOSER
TO NORMAL. THE FORECAST IS DRY FOR THE BULK OF THE FORECAST
PERIOD...WITH A COLD FRONT POTENTIALLY APPROACHING FROM THE
NORTHWEST LATE IN THE WEEKEND.
&&
.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
WIDESPREAD CONVECTION AND IFR CONDITIONS WILL IMPACT THE TERMINALS
THIS MORNING INTO MAYBE EARLY AFTERNOON...AS A SQUALL LINE IN
ADVANCE OF A STRONG COLD FRONT MOVES THROUGH. GUSTY
WINDS...FREQUENT LIGHTNING AND HEAVY RAINFALL WILL OCCUR WITH SOME
OF THE STRONGER ACTIVITY. WINDS WILL BECOME GUSTY AT BOTH SITES
THIS AFTERNOON IN WAKE OF THE SQUALL LINE AS MIXING HEIGHTS TAP
INTO STRONGER WINDS JUST OFF THE DECK. THERE COULD STILL BE A FEW
RENEGADE SHOWERS LATE TODAY/THIS EVENING UNTIL THE COLD FRONT
CLEARS THE AIRFIELDS...BEFORE THE COLD FRONT BLAST THROUGH 04-06Z.
STRONG AND GUSTY WINDS AND GRADUAL IMPROVEMENT TO VFR WEATHER WILL
TRANSPIRE.
EXTENDED AVIATION OUTLOOK...VFR. GUSTY W/NW WINDS MONDAY THROUGH
TUESDAY.
&&
.MARINE...
TODAY...PINCHING IS OCCURRING NORTH OF THE WARM FRONT THAT WAS
FOUND ACROSS OUR SOUTHERNMOST WATERS EARLY THIS MORNING. WE/LL BE
CLOSE BUT NOT QUITE TO THE SCA CRITERIA WITH THIS SYNOPTIC
SITUATION ACROSS OUR 0-20 NM WATERS AND CHARLESTON HARBOR.
HOWEVER...THE WARM FRONT WILL LIFT STEADILY NORTH TODAY...FINALLY
STALLING ACROSS OR NEAR THE CHARLESTON COUNTY WATERS THIS
AFTERNOON...AS A WAVE OF LOW PRESSURE FORMS ALONG THE FRONT AND
MOVES NE. WINDS WILL VEER TO THE SOUTH AND SW AND INCREASE ENOUGH
WHERE GUSTS OF 5 KT WILL OCCUR. THUS WE HAVE INITIATED SCA/S FOR
THE MID AND LATE MORNING ACROSS AMZ350-352-354 AS A RESULT.
CONDITIONS IN CHARLESTON HARBOR LOOK TO STAY JUST BELOW THE
NECESSARY SCA CRITERIA. MEANWHILE...THE OUTER GA WATERS ALREADY
HAVE AN SCA IN EFFECT FOR SOME 6 FOOT SEAS AND AS SW WINDS CLIMB
TO 20-25 KT THESE SEAS WILL BUILD FURTHER. SUFFICE TO SAY THAT THE
SCA WILL PERSIST. MARINERS ARE ADVISED THAT SCATTERED T-STORMS
WILL OCCUR TODAY...A FEW OF WHICH WILL BECOME STRONG OR SEVERE
WITH FREQUENT LIGHTNING...WIND GUSTS PAST 35 OR 40 KT AND POSSIBLY
EVEN ISOLATED WATERSPOUTS.
TONIGHT...THE PRESSURE PATTERN BECOMES MUCH MORE RELAXED THIS
EVENING...BUT THIS IS ONLY TEMPORARY WAITING FOR THE PASSAGE OF A
STRONG COLD FRONT THE SECOND PART OF THE NIGHT. STRONG COLD
ADVECTION WILL MIX PLENTY OF THE 40-45 KT GEOSTROPHIC WINDS...AND
THAT ALONG WITH STEADY ISALLOBARIC PRESSURE RISES WILL RESULT IN
GALE FORCE CONDITIONS DEVELOPING. WE HAVE RAISED A GALE WARNING
FOR ALL ATLANTIC WATERS...WITH A GALE WATCH IN CHARLESTON HARBOR.
MONDAY THROUGH THURSDAY...DEEPENING LOW PRESSURE WILL PULL AWAY FROM
THE EAST COAST ON MONDAY. AS IT DOES...A TIGHT PRESSURE GRADIENT AND
STRONG LOW LEVEL JET COMBINED WITH COLD ADVECTION WILL RESULT IN AN
ONGOING GALE EVENT MONDAY MORNING. MODEL SOUNDINGS SHOW FREQUENT
GALES CONTINUING TO OCCUR ACROSS ALL WATERS OUTSIDE OF THE
CHARLESTON HARBOR WHERE IT WILL BE CLOSE TO GALE WARNING CONDITIONS.
GALES WILL PERSIST THROUGH THE DAY AND INTO THE EVENING HOURS.
THEREAFTER...SOLID SMALL CRAFT ADVISORY CONDITIONS WILL LINGER
THROUGH TUESDAY NIGHT. THE GRADIENT WILL FINALLY RELAX BY MID WEEK
AS THE SURFACE HIGH MOVES INTO THE REGION.
