The episode as NWS CHS wrote it up.
An area of low pressure and associated cold front pushed through the southeast where kinematic profiles and anomalously cold air aloft existed. This lead to the development of strong storms over portions of southeast Georgia.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
139 AM EDT SAT APR 11 2009
.SYNOPSIS...
A COLD FRONT WILL APPROACH FROM THE WEST TONIGHT AND PUSH OFFSHORE
SATURDAY MORNING. HIGH PRESSURE WILL BUILD DOWN THE EAST COAST
SATURDAY NIGHT THROUGH SUNDAY NIGHT. A WARM FRONT WILL LIFT
NORTHWARD TOWARD THE REGION MONDAY...AND PUSH NORTH OF THE AREA
MONDAY NIGHT. A COLD FRONT WILL MOVE THROUGH THE REGION TUESDAY
NIGHT...WITH HIGH PRESSURE THEN BUILDING BACK INTO THE AREA
WEDNESDAY THROUGH THURSDAY. ANOTHER STORM SYSTEM MAY IMPACT THE
AREA BY THE END OF THE UPCOMING WORK WEEK.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
A FAIRLY SOLID LINE OF CONVECTION IS FOUND FROM THE SC MIDLANDS TO
EAST CENTRAL GA...WITH A SECOND CLUSTER OF CONVECTION FROM WEST
CENTRAL GA TO SE AL. LOCAL RADARS ARE INDICATING ONE SUPER CELL
APPROACHING CAE FROM THE WEST...WITH STRONG STORMS FURTHER SW IN
PARTS OF GA...BUT FAR UPSTREAM FROM THE CWFA.
THE MAIN CONCERN FOR TONIGHT REMAINS THE POTENTIAL FOR STRONG OR
SEVERE STORMS. WIND FIELDS ARE IMPRESSIVE WITH A 40-50 KT LOW
LEVEL JET TO MOVE THROUGH OVERNIGHT...IN SYNC WITH LEFT FRONT
QUAD OF 100-120 KT UPPER LEVEL JET. KINEMATICS ARE FAVORABLE WITH
STEEP MID LEVEL LAPSE RATES...LOW WET BULBS AROUND 8-10K FT AND
COLD MID LEVEL TEMPS WHERE 500 MB READINGS AS AS LOW AS -16 TO
-18C. TOTAL TOTAL INDEX OF 50-52 STILL SUGGESTS THERE COULD BE
ISOLATED SEVERE STORMS INLAND...WHILE BULK SHEAR AND HELICITY
VALUES ARE SUGGESTIVE OF SMALL SPIN UPS...WITH STRONG RIGHT CURVED
HODOGRAPHS. IN ADDITION...THERE IS ENOUGH OF AN INCREASE IN DEW
POINTS...WITH UPPER 50S AND LOWER 60S TO PERSIST THROUGH THE
NIGHT...WHILE SURFACE MIXING RATIO IS 10-12 G/KG. NEGATING
FACTORS LOOK TO HOW MUCH DOES DIURNAL COOLING COME INTO
PLAY...SBCAPES WILL BE GENERALLY 500-1000 J/KG AND BEST SHORT WAVE
ENERGY BEGINS TO LIFT OUT TO THE ENE ACROSS NC AND VA OVERNIGHT.
IN ADDITION...AIR MASS AS PER KCHS SOUNDING REVEALS A COOL
BOUNDARY LAYER AND LIMITED INSTABILITY. HOWEVER...AT LEAST PART OF
THAT IS A RESULT OF STABILIZING EFFECTS OF THE AFTERNOON/EVENING
SEA BREEZE.
WE WILL CONTINUE TO SHOW THE BEST RISK OF ANY SEVERE WEATHER OVER
THE NW HALF OF THE CWFA...WITH THE HIGHEST PROBABILITIES OVER THE
NW TIER...AND WE WILL ADD MENTION OF POSSIBLE DAMAGING WINDS AND
LARGE HAIL. SEVERE TSTM WATCH 138 IN NOW IN EFFECT FOR ALL OF SC
AND ALL INLAND COUNTIES EXCEPT LONG COUNTY IN SE GA UNTIL 6 AM.
TORNADO RISK IS TOO LOW TO MENTION IN THE FORECAST...BUT WE WILL
KEEP MENTION IN THE HAZARDOUS WEATHER OUTLOOK.
WE WILL INCREASE RAIN CHANCES INTO THE LIKELY RANGE NW...BUT
MAINTAIN LITTLE TO NO CHANCE FAR SE.
MODERATE TO STRONG S-SW WINDS ACROSS COASTAL SC AND LIGHT TO
MODERATE FLOW MOST ELSEWHERE...ALONG WITH WARM AIR ADVECTION THE
FIRST PART OF THE NIGHT WILL PREVENT TEMPS FROM DROPPING MUCH THE
NEXT SEVERAL HOURS. HOWEVER...EVAPORATE COOLING WILL DEVELOP WITH
THE ONSET OF THE SHOWERS/TSTMS AND WINDS WILL DROP OFF
LATE...ENOUGH TO ALLOW FOR TEMPS TO FALL INTO THE LOWER AND MIDDLE
60S OVER THE VAST MAJORITY OF THE FORECAST AREA.
LAKE WINDS...A LAKE WIND ADVISORY FOR LAKE MOULTRIE REMAINS IN
EFFECT...WITH RECENT OBSERVATIONS FROM THE AREA SHOWING 20 TO OCNL
25 KT. STRONG LOW LEVEL WINDS AND A TIGHT SURFACE PRESSURE GRADIENT
WILL PERSIST AND COMBINE TO PRODUCE WINDS OF 20 TO 25 KT THROUGH
EARLY SATURDAY MORNING.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM TODAY/...
THERE WILL BE A LINGERING RISK FOR SHOWERS AND TSTMS THROUGH
SUNRISE SATURDAY...MAINLY ALONG AND EAST OF INTERSTATE 95. ANY
SHOWER AND TSTM ACTIVITY SHOULD PUSH OFFSHORE BY 14-15Z IS
FORECAST TO BE OFFSHORE BY THEN. WILL HOLD ONTO A SLIGHT CHANCE
FOR MEASURABLE PRECIPITATION THROUGH MID-MORNING WITH DRY WEATHER
PREVAILING THEREAFTER. SHOULD SEE SOME FAIRLY RAPID CLEARING
THROUGH THE DAY AS MID-LEVEL TRAJECTORIES BECOME DOWNSLOPE
DOMINATED. EXPECT MOSTLY SUNNY SKIES TO PREVAIL BY EARLY
AFTERNOON IF NOT BEFORE. EXPECT HIGHS IN THE UPPER 70S TO LOWER
80S...WARMEST ACROSS THE SOUTHERN HALF OF THE FORECAST AREA.
&&
.LONG TERM /TONIGHT THROUGH FRIDAY/...
MEDIUM RANGE GUIDANCE IS IN FAIRLY GOOD AGREEMENT THROUGH THE
EXTENDED PERIOD THIS AFTERNOON. HIGH PRESSURE WILL BUILD INTO THE
AREA FROM THE NORTH SATURDAY NIGHT THROUGH SUNDAY NIGHT...BEFORE
SHIFTING OFFSHORE AND INTO THE ATLANTIC MONDAY AS A WARM FRONT
BEGINS TO LIFT NORTHWARD TOWARD THE REGION. THE WARM FRONT WILL LIFT
NORTH OF THE REGION MONDAY NIGHT...WITH A COLD FRONT THEN SWEEPING
BACK THROUGH THE AREA TUESDAY NIGHT. HIGH PRESSURE WILL THEN BUILD
BACK INTO THE AREA WEDNESDAY THROUGH THURSDAY NIGHT. ANOTHER STORM
SYSTEM MAY THEN TRY TO WORK ITS WAY INTO THE REGION FRIDAY.
AS FOR SENSIBLE WEATHER...WILL KEEP THE FORECAST RAIN FREE SATURDAY
NIGHT THROUGH SUNDAY EVENING. AS ISENTROPIC ASCENT/WARM AIR
ADVECTION BEGINS TO DEVELOP AFTER MIDNIGHT SUNDAY AS THE WARM FRONT
BEGINS TO PUSH INTO THE AREA...COULD SEE A FEW SHOWERS ACROSS
PRIMARILY SOUTHEAST GEORGIA ZONES...SO HAVE INCLUDED SLIGHT
CHANCE/LOW CHANCE POPS HERE. RAIN CHANCES LOOK PRETTY GOOD IN THE
MONDAY THROUGH TUESDAY TIME FRAME IN ASSOCIATION WITH THE WARM FRONT
AND COLD FRONT PUSHING THROUGH THE REGION...SO HAVE INCREASED POPS
INTO THE HIGH CHANCE/LOW END LIKELY RANGE. DEEPEST MOISTURE IS
EXPECTED TO HAVE SHIFTED EASTWARD AND INTO THE ATLANTIC TUESDAY
NIGHT...BUT COULD SEE A LINGERING SHOWER/THUNDERSTORM ALONG FAR
NORTHEASTERN ZONES...SO WILL KEEP SLIGHT CHANCE POPS GOING HERE WITH
RAIN FREE WEATHER ELSEWHERE. RAIN FREE WEATHER IS THEN EXPECTED
WEDNESDAY THROUGH THURSDAY NIGHT AS HIGH PRESSURE BUILDS BACK INTO
THE AREA. MODEL AGREEMENT DIMINISHES QUICKLY BY FRIDAY...BUT BOTH
THE GFS AND ECMWF DO INDICATE SOME SORT OF SYSTEM WILL BEGIN TO
APPROACH THE REGION WITH DEEP MOISTURE INCREASING ACROSS THE
REGION...SO WILL INCLUDE SLIGHT CHANCE POPS ACROSS THE AREA.
TEMPERATURES ARE EXPECTED TO RUN SEVERAL DEGREES BELOW CLIMO SUNDAY
AND MONDAY...THEN REBOUND BACK CLOSER TO NORMAL TUESDAY THROUGH
FRIDAY.
&&
.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
VFR CONDITIONS ARE EXPECTED TO PREVAIL AT THE TERMINALS THROUGH
06Z SUNDAY...ALTHOUGH TEMPORARY REDUCTIONS TO MVFR LEVELS ARE
POSSIBLE IN SCATTERED SHOWERS AND THUNDERSTORMS AT KCHS IN THE
07-10Z TIME FRAME. LIMITED POTENTIAL FOR CONVECTION AT KSAV...THUS
NO MENTION IN THE TAF.
ALTHOUGH SURFACE WINDS WILL REMAIN COUPLED THROUGH THE NIGHT...STRONG
WIND FIELDS ALOFT /UP TO 45 KT AT 2K FT/ WILL REQUIRE LOW LEVEL
WIND SHEAR IN THE KCHS AND KSAV TAF THROUGH ABOUT 13Z. LOW LEVEL
JETTING QUICKLY DIMINISHES BY MID MORNING HOWEVER.
FOR THE BULK OF SATURDAY...A DRY AND SINKING AIR MASS WILL OVERTAKE
THE AREA WITH DOWNSLOPING WEST AND NORTHWEST WINDS OFF THE
APPALACHIANS. THIS WILL RESULT IN MOSTLY CLEAR OR CLEAR SKIES
THROUGH MUCH OF THE DAY. SOME WIND GUSTS COULD REACH 20 KT AT TIMES
AT BOTH TERMINALS IN THE AFTERNOON.
EXTENDED AVIATION OUTLOOK...MVFR CONDITIONS ARE POSSIBLE MONDAY
INTO TUESDAY DUE TO SCATTERED SHOWERS AND THUNDERSTORMS.
OTHERWISE...VFR CONDITIONS EXPECTED.
&&
.MARINE...
STRONG LOW LEVEL JET OF 40-50 KT WILL MOVE INTO THE MARINE
COMMUNITY TONIGHT...AND ALTHOUGH MIXING WILL BE SOMEWHAT LIMITED
WITH WARM AIR ADVECTION AHEAD OF THE COLD FRONT...WE WILL OBTAIN
AS MUCH AS 60 PERCENT OF THE 30-40 KT OF GEOSTROPHIC WINDS AT 1000
MB. GIVEN THAT WINDS WILL INCREASE FURTHER THROUGH THE NIGHT AND
ARE ALREADY GUSTING NEAR 25 KT AT GRAYS REEF...FRP2 AND A REPORT
FROM THE SAVANNAH PILOT BOAT AT BUOY C...WE ARE GOING TO RAISE AN
SCA FOR AMZ352 AND AMZ354. THUS ALL WATERS WILL NOW HAVE AN SCA
THROUGH THE NIGHT...AND INTO THE LATE MORNING FOR THE OUTER GA
WATERS AND AMZ350. WITH S-SW WINDS OF 20-25 KT AND GUSTY
TONIGHT...SEAS WILL CLIMB AS HIGH AS 6 OR 7 FT...HIGHEST FAR NORTH
AND ACROSS THE OUTER GA WATERS.
WINDS WILL TURN OFFSHORE AND DIMINISH SATURDAY MORNING AS A COLD
FRONT SHIFTS OFF THE COAST.
SATURDAY NIGHT THROUGH WEDNESDAY...HIGH PRESSURE WILL BUILD INTO
THE AREA FROM THE NORTH SATURDAY NIGHT THROUGH SUNDAY NIGHT...
BEFORE SHIFTING FURTHER EAST INTO THE ATLANTIC MONDAY AS A WARM
FRONT LIFTS NORTHWARD TOWARD THE WATERS. THE WARM FRONT WILL LIFT
NORTH OF THE WATERS MONDAY NIGHT...WITH A COLD FRONT THEN SWEEPING
BACK THROUGH THE AREA TUESDAY NIGHT. HIGH PRESSURE WILL THEN BUILD
BACK INTO THE REGION WEDNESDAY.
EXPECT A FAIRLY GOOD SURGE AS HIGH PRESSURE BUILDS IN FROM THE NORTH
SATURDAY NIGHT AND SUNDAY...AND MAY EVENTUALLY NEED SMALL CRAFT
ADVISORIES FOR PORTIONS OF THE WATERS. FAVORABLE FETCH MAY RESULT IN
SEAS REMAINING IN THE SMALL CRAFT RANGE ACROSS THE OUTER GEORGIA
WATERS SUNDAY NIGHT AS WELL...WITH THE REMAINING WATERS DROPPING
BELOW SMALL CRAFT LEVELS.
WINDS ARE EXPECTED TO INCREASE AS A WARM FRONT LIFTS NORTHWARD
TOWARDS THE WATERS MONDAY...AND THROUGH THE THE WATERS MONDAY NIGHT.
SMALL CRAFT ADVISORIES MAY AGAIN BE NEEDED FOR MOST MARINE ZONES
LATE MONDAY THROUGH MONDAY NIGHT.
GRADIENT IS EXPECTED TO DECREASE QUICKLY TUESDAY MORNING...AND
SHOULD SEE WINDS/SEAS DROP BELOW SCA LEVELS ACROSS ALL WATERS BY
TUESDAY AFTERNOON. WINDS/SEAS SHOULD THEN REMAIN BELOW SMALL CRAFT
THRESHOLDS TUESDAY NIGHT AND WEDNESDAY.
