What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Mar 26, 4:42 PM EDT, 2 hours 34 minutes earlier.

Area forecast discussion, Mar 26, 4:42 PM EDT, 2 hours 34 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
442 PM EDT SAT MAR 26 2011

.SYNOPSIS...
A SERIES OF WEAK LOW PRESSURE SYSTEMS WILL MOVE EAST ALONG
A STATIONARY FRONT THROUGH MONDAY. HIGH PRESSURE WILL BRIEFLY
BUILD FROM THE NORTH EARLY NEXT WEEK...BEFORE ANOTHER FRONTAL
SYSTEM CROSSES THE REGION WEDNESDAY. AN UNSETTLED PATTERN WILL
THEN CONTINUE THROUGH THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
A PRONOUNCED SURFACE FRONT REMAINS DRAPED FROM WEST TO EAST
ACROSS THE FORECAST AREA THIS AFTERNOON...APPROXIMATELY FROM MACON
TO SYLVANIA TO MONCKS CORNER. SEVERAL WEAK SHORTWAVES EMBEDDED IN
A NEARLY ZONAL UPPER LEVEL FLOW HAVE SPURRED SCATTERED SHOWERS AND
THUNDERSTORMS UPSTREAM OF OUR AREA AND SLOWLY MOVING INTO WESTERN
PORTIONS. MOSTLY SUNNY SKIES PREVAILED FOR MUCH OF THE DAY WHICH
ALLOWED TEMPS TO REACH NEAR THICKNESS PROGS OF UPPER 70S TO LOWER
80S. HOWEVER LOW-LEVEL MOISTURE HAS ONLY RECENTLY BEGUN TO
INCREASE NOW THAT THE H85 FLOW IS INCREASING AND BACKING.
THEREFORE DEWPOINTS HAVE ONLY REACHED THE LOWER 60S ACROSS FAR
INTERIOR SOUTHEAST GA WHILE THE REMAINDER OF THE AREA STILL SEES
LOWER TO MIDDLE 50S DEWPOINTS WHICH MIXED OUT EARLIER IN THE DAY.
THE BOTTOM LINE IS THAT THE MOST CONVECTION-FRIENDLY AIRMASS
REMAINS LIMITED TO INTERIOR SOUTHEAST GA AND WILL ONLY SLIGHTLY
EXPAND THROUGH LATE AFTERNOON BEFORE WE LOSE DIURNAL HEATING.

THE FIRST ROUND OF CONVECTION WILL PROBABLY BEGIN A DOWNWARD TREND
THROUGH EARLY THIS EVENING ONCE THE AIRMASS GETS WORKED OVER AND
CLOUDS BLOCK FURTHER INSOLATION. THE FRONT SHOULD DRIFT SOUTHWARD
OVERNIGHT WHILE ANOTHER FEW SHORTWAVE DISTURBANCES MOVE EAST
THROUGH CENTRAL/SOUTHERN SC. BEST CHANCE FOR SHOWERS AND ISOLATED
TSTMS WILL BE ACROSS SOUTHERN SC AND THE ADJACENT WATERS OVERNIGHT
WHICH IS WHERE WE HAVE INDICATED THE HIGHEST POPS. SEVERE
POTENTIAL SHOULD DIMINISH RAPIDLY AFTER ABOUT 7 PM.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/...
WAVES OF LOW PRESSURE WILL CONTINUE TO DEVELOP ALONG A LINGERING
FRONT DRAPED ACROSS THE NORTHERN SECTIONS OF THE FORECAST AREA
SUNDAY MORNING. THE FRONT IS EXPECTED TO DRIFT SOUTHWARD THROUGH
THE DAY...PROVIDING THE NECESSARY SURFACE BASED CONVERGENCE TO
SUPPORT ANOTHER ROUND OF STRONG TO POTENTIALLY SEVERE
THUNDERSTORMS SUNDAY AFTERNOON.

THERE CONTINUES TO BE CONSIDERABLE DISAGREEMENT BETWEEN THE GFS
AND NAM REGARDING DETAILS OF THE FRONTAL PROGRESSION AND ASSOCIATED
SENSIBLE WEATHER FOR SUNDAY. THE SLOWER GFS SOLUTION APPEARS TO BE
THE OUTLIER...WHILE OTHER MODELS SUCH AS THE NAM AND SREF ARE IN
AGREEMENT WITH A MORE RAPID SOUTHWARD DESCENT OF THE FRONT. HIGH
TEMPERATURES ACCORDING TO THE NAM ARE MUCH COOLER ...LIKELY A
RESULT OF THE EARLIER INITIATION OF NORTHERLY WINDS BEHIND THE
FRONT. TEMPERATURES COULD BE SUPPRESSED IN THE LOWER 60S ACROSS
NORTHERN BERKELEY COUNTY IN SOUTH CAROLINA...YET RISE INTO THE
UPPER 70S SOUTH OF THE SAVANNAH RIVER AHEAD OF THE DESCENDING
FRONT.

THIS SIGNIFICANT TEMPERATURE GRADIENT COULD PROVIDE A CLUE AS TO
WHICH SECTIONS OF THE FORECAST AREA ARE AT GREATEST RISK FOR
SEVERE THUNDERSTORM DEVELOPMENT SUNDAY...AS LOCATIONS REMAINING
WITHIN THE WARM SECTOR OF THE SYSTEM WILL LIKELY EXPERIENCE THE
GREATEST DESTABILIZATION DURING THE PEAK HEATING TIME OF THE DAY.
INSTABILITY PARAMETERS CONTINUE TO LOOK QUITE CONDUCIVE TO SUPPORT
ORGAN ZED CONVECTION...WITH CAPE VALUES UP TO 1200 J/KG AND LIFTED
INDICES DOWN TO -3 ACROSS SOUTHEAST GEORGIA. SHEAR PROFILES ARE
ALSO DECENT...WITH THE NAM EVEN HINTING AT A COUPLED JET
SIGNATURE SUNDAY AFTERNOON...WHILE LAPSE RATES PEAK OVER 7 C/KM.
AS A RESULT OF THESE FAVORABLE CONVECTIVE INGREDIENTS...STORM
PREDICTION CENTER HAS KEPT THE FORECAST AREA WITHIN A SLIGHT RISK
ZONE FOR DAY 2. LATEST THINKING IS THAT THE MAIN HAZARDS WILL BE
DAMAGING WINDS AND LARGE HAIL WITHIN ANY SEVERE THUNDERSTORMS.
ALTHOUGH AN ISOLATED TORNADO CANNOT BE COMPLETELY RULED
OUT...UNIDIRECTIONAL FLOW WOULD SUGGEST LESS OF A POTENTIAL FOR
TORNADIC SUPERCELLS.

THUNDERSTORM ACTIVITY IS EXPECTED TO DIMINISH SUNDAY EVENING...A
COMBINED RESULT OF DECREASING DIURNAL INSTABILITY AND MORE STABLE
AIR MOVING INTO THE REGION BEHIND THE FRONT. DESPITE DWINDLING
THUNDER...SHOWER CHANCES WILL REMAIN IN THE 30 TO 40 PERCENT RANGE
OVERNIGHT WITH THE FRONT LINGERING TO THE SOUTH AND SHORTWAVE
ACTIVITY CONTINUING TO TRACK ALONG ZONAL FLOW ALOFT. THE AIR MASS
CHANGE WILL BE QUITE NOTICEABLE...WITH MUCH COOLER TEMPERATURES
EXPECTED SUNDAY NIGHT AND MONDAY. HIGH TEMPERATURES ON MONDAY
COULD BE SUPPRESSED IN THE UPPER 50S ACROSS SOUTH CAROLINA
ZONES TO THE LOW TO MID 60S SOUTHEAST GEORGIA.

AN UNSETTLED PATTERN WILL REMAIN THROUGH EARLY NEXT WEEK. ANOTHER
SURFACE WAVE WILL DEVELOP ALONG THE BOUNDARY...PULLING THE FRONT
BACK INTO THE REGION BEFORE TRACKING OFFSHORE. HAVE MAINTAINED
POPS IN THE 20 TO 30 PERCENT RANGE FOR MONDAY AND MONDAY NIGHT
ACCORDINGLY...WITH LITTLE CHANCE FOR THUNDER UNDER A MUCH MORE
STABLE ATMOSPHERE. SURFACE HIGH PRESSURE WILL THEN BUILD INTO THE
REGION FROM THE NORTH...AND EXPECT ONLY A SLIGHT CHANCE FOR
SHOWERS ACROSS SOUTHEAST GEORGIA BY TUESDAY. TEMPERATURES ON
TUESDAY WILL BE A FEW DEGREES WARMER THAN MONDAY...REACHING THE
UPPER 60S TO LOWER 70S WITHIN INCREASINGLY ONSHORE FLOW.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
OVERALL CONFIDENCE IN THE MEDIUM RANGE DECREASES QUICKLY AFTER MID
WEEK. ANOTHER FRONTAL SYSTEM WITH DECENT MID LEVEL INSTABILITY
PARAMETERS IS A GOOD BET TO AFFECT THE REGION ON WED. SCT SHOWERS AND
TSTMS SEEM A GOOD BET WED BUT THE MORE IMPRESSIVE UPPER SUPPORT IS
EXPECTED TO BE OFF TO OUR N. STRONG WARM AIR ADVECTION PATTERN SHOULD
PUSH HIGHS BACK INTO THE 70S ALL AREAS ON WED DESPITE THE CLOUDS AND
CONVECTION CHANCES. THE FRONT WILL GET HUNG UP SOMEWHERE FROM THE
FLORIDA TO THE CAROLINAS AND THE POSITION IS CRITICAL ON WHERE YET
ANOTHER SYSTEM TRACKS LATE WEEK. HIGH PRES SHOULD RETURN BY EARLY
NEXT WEEKEND WITH TEMPERATURES PROBABLY CLOSE TO CLIMO.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
A FRONTAL BOUNDARY DRAPED ACROSS THE AREA WILL RESULT IN
DETERIORATING CONDITIONS AT BOTH TAF SITES OVERNIGHT INTO SUNDAY
MORNING. RAIN SHOWERS WILL BE POSSIBLE THROUGH THIS EVENING AT
EITHER SITE BUT THE BETTER CHANCE LOOKS TO BE AT CHS LATER THIS
EVENING AS ASCENT INCREASES ALONG THE SOUTHERN EDGE OF THE FRONT.
CEILINGS SHOULD BEGIN TO LOWER THIS EVENING WITH MVFR CONDITIONS
AT BOTH TERMINALS BY EARLY SUNDAY MORNING. FAIRLY GOOD CHANCE FOR
IFR CEILINGS AT CHS ONCE THE FRONT DROPS SOUTH TOWARD THE SAVANNAH
RIVER SO WE WENT AHEAD AND ADDED PREVAILING IFR STARTING AT 12Z.
STILL THE POTENTIAL FOR SOME BRIEF IFR AT SAV AROUND DAYBREAK SUN
BUT WE EXPECT THE FRONT TO STAY JUST FAR ENOUGH NORTH TO PRECLUDE
MENTION IN TAFS AT THIS TIME. CEILINGS AT CHS WILL PROBABLY
RECOVER TO SLIGHTLY ABOVE 1000 FT BY EARLY AFTERNOON BUT DROP BACK
INTO IFR LATE AFTERNOON INTO THE EVENING HOURS.

EXTENDED AVIATION OUTLOOK...MVFR OR LOWER CONDITIONS ARE POSSIBLE
OVER SOUTHEAST SOUTH CAROLINA ON SUNDAY...DEPENDENT ON THE FRONTAL
POSITION AND TIMING/AMOUNT OF CONVECTIVE RAINS. MVFR/IFR
CONDITIONS ARE LIKELY TO FILL IN OVER THE COASTAL CORRIDOR IN THE
WAKE OF THE FRONT SUNDAY NIGHT AND LINGER INTO MID WEEK.

&&

.MARINE...
A LOW-LEVEL JET WILL INCREASE IN STRENGTH THIS EVENING AND
OVERNIGHT ALTHOUGH THE SW FETCH WILL NOT LEND TO VERY GOOD MIXING
PROFILES. THUS...THE 40-45 KT 925 MB JET WILL ONLY RESULT IN
SURFACE WINDS OF 15-20 KT BY LATE TONIGHT.

A COLD FRONT WILL DESCEND THROUGH THE MARINE ZONES ON SUNDAY...WITH
WINDS STEADILY VEERING TO THE NORTH/NORTHEAST IN IT WAKE. ALTHOUGH
COOLER AIR FILTERING INTO THE REGION BEHIND THE FRONT WILL ENHANCE
MIXING POTENTIAL OVER THE WATERS SUNDAY NIGHT THROUGH MONDAY...A
20 TO 30 KT LOW LEVEL JET WILL BE QUITE TRANSIENT...AND NUMEROUS
WAVES OF LOW PRESSURE TRACKING ALONG THE BOUNDARY WILL PREVENT A
STRONG TIGHTENING OF THE GRADIENT. EXPECT SOME SURGING TO
OCCUR...HOWEVER WILL KEEP WINDS AND SEAS JUST BELOW ADVISORY
CRITERIA THROUGH TUESDAY.

SURFACE FLOW WILL SHIFT SOUTHEAST/SOUTH AND EVENTUALLY SOUTHWEST
BY THE MIDDLE OF THE WEEK AS THE NEXT SYSTEM APPROACHES. WINDS AND
SEAS COULD BE NEAR SMALL CRAFT ADVISORY CRITERIA OVER OUTER GEORGIA
WATERS WEDNESDAY.
