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 Apr 5, 1:45 PM EDT, 35 minutes earlier.

Area forecast discussion, Apr 5, 1:45 PM EDT, 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
145 PM EDT SAT APR 5 2008

.SYNOPSIS...
A COLD FRONT WILL APPROACH FROM THE NW THIS EVENING...AND IS EXPECTED
TO MOVE ACROSS THE AREA LATE TONIGHT INTO EARLY SUN. HIGH PRES WILL
BUILD FROM THE N LATER SUN. A WEAK WAVE OF LOW PRES WILL TRACK JUST
S OF THE REGION SUN NIGHT INTO MON. HIGH PRES WILL THEN REBUILD OVER
THE AREA TUE THROUGH FRI.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
STRENGTHENING SHORTWAVE TROUGH NOW ACROSS THE LOWER MISSISSIPPI
VALLEY SHOWS UP CLEARLY ON MORNING WATER VAPOR IMAGERY. LARGE AREA
OF SHOWERS AND THUNDERSTORMS IS ONGOING AHEAD OF THIS FEATURE IN
THE DEEP SOUTH WITH A FEW IMPRESSIVE LINEAR MCS/S AFFECTING
AL/GA/FL. LIGHT TO MODERATE RAIN SHOWERS AFFECTING OUR WESTERN
ZONES...MAINLY IN A REGION OF INCREASING UPPER DIVERGENCE BELOW A
140 KT JET. THE SETUP FOR THIS AFTERNOON AND EVENING REMAINS
FAVORABLE FOR SOME SEVERE THUNDERSTORMS ACROSS OUR ENTIRE AREA.
THE AFOREMENTIONED SHORTWAVE IS EXPECTED TO LIFT NE THROUGH THE TN
VALLEY TONIGHT. THIS WAVE CURRENTLY HAS A SLIGHTLY POSITIVE TILT
WHICH IS LESS CONDUCIVE TO SEVERE THUNDERSTORMS DUE TO THE
CONVERGENT FLOW ALOFT. AS IT LIFTS NE TODAY...IT SHOULD TAKE ON A
MORE NEUTRAL TILT WHICH SHOULD SUPPORT DEEPER...MORE ROBUST
UPDRAFTS. ALTHOUGH LOW-LEVEL CLOUD COVER IS EXTENSIVE THIS
MORNING...AN INCREASE IN DEWPOINTS TO BETWEEN 68 AND 71 THIS
AFTERNOON WILL INCREASE CAPES DRASTICALLY. THEREFORE...ANY BREAKS
IN THE CLOUDS WILL ONLY PROVIDE ADDITIONAL INSTABILITY AHEAD OF
THE PRIMARY UPPER FORCING.

BEST COVERAGE OF SHOWERS AND STORMS STILL LOOKS TO BE DURING THE
LATTER HALF OF THE AFTERNOON THROUGH THE EVENING. BOTH THE GFS AND
NAM UPPER DIVERGENCE FIELDS ARE STRIKINGLY SIMILAR SHOWING A
BULLSEYE OVER THE AREA AT 00Z...WITH A GRADUAL INCREASE THROUGH
THAT TIME. CURRENT PRECIP SHIELD MATCHES UP WELL WITH THE BEST
MODEL UPPER DIVERGENCE SO WE FEEL THIS WILL BE A GOOD INDICATOR
FOR PRECIP COVERAGE. PRECIPITABLE WATER VALUES WERE 1.59 ON THE
MORNING SOUNDING AND SHOULD CONTINUE TO INCREASE TO AS HIGH AS
1.9 THIS AFTERNOON AS STRONG WARM...MOIST ADVECTION CONTINUES
FROM THE SSW. THIS AIRMASS COUPLED WITH GOOD UPPER SUPPORT WILL BE
FAVORABLE FOR VERY HEAVY RAINFALL IN ANY SHOWERS AND STORMS. HAVE
ADDED MENTION OF LOCALIZED FLOODING TO HWO AND HEAVY RAIN WORDING
TO FORECAST.

AS A SFC LOW DEVELOPS ALONG THE COLD FRONT TO OUR WEST TODAY
LOW-LEVEL HELICITY SHOULD INCREASE. ADDITIONALLY...THE SEABREEZE
WILL PROVIDE ENHANCED STORM-RELATIVE HELICITY LATE IN THE
AFTERNOON...THUS ISOLATED TORNADOES CANNOT BE RULED OUT. WILL
MAINTAIN MENTION IN HWO. PRIMARY SEVERE WEATHER THREAT STILL LOOKS
TO BE FROM HAIL AND DAMAGING WINDS FROM 4 PM UNTIL 10 PM.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SUNDAY/...
WE HAVE CARRIED THE SEVERE WEATHER RISK TO AROUND MIDNIGHT AND
THEN ALLOWED POPS TO DIMINISH FROM W TO E AS THE SFC FRONTAL
BOUNDARY APPROACHES. SOMEWHAT SLOWER MODEL TIMING HAS BUMPED OUR
POPS UPWARD IN OUR EASTERN ZONES AND FORCED SOME WARMER OVERNIGHT
LOWS TO THE EAST OF I-95. S TO SW WINDS SHOULD DIMINISH AS THE LOW
LEVEL JET EASES OFF THE COAST.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
MEDIUM RANGE GUIDANCE IS IN FAIRLY GOOD AGREEMENT THROUGH MUCH OF
THE EXTENDED PERIOD THIS MORNING. THE COLD FRONT WILL PUSH EASTWARD
AND OFF THE SOUTH CAROLINA AND GEORGIA COAST SUNDAY MORNING...
FOLLOWED BY A WEAK RIDGE OF HIGH PRESSURE BUILDING INTO THE REGION
DURING THE AFTERNOON HOURS. A WAVE OF LOW PRESSURE WILL PASS BY TO
THE SOUTH OF THE FORECAST AREA SUNDAY NIGHT AND MONDAY...FOLLOWED
BY HIGH PRESSURE BUILDING BACK INTO THE REGION MONDAY NIGHT
THROUGH FRIDAY. AS FOR FORECAST DETAILS...WILL CARRY SLIGHT CHANCE
POPS FRIDAY MORNING AS FRONTAL BOUNDARY PUSHES OFFSHORE...THEN GO
WITH A RAIN FREE FORECAST SUNDAY AFTERNOON. WILL HAVE TO CARRY
SLIGHT CHANCE POPS SUNDAY NIGHT AND MONDAY AS WAVE OF LOW PRESSURE
PASSES BY TO THE SOUTH OF THE REGION. MID- LEVEL LAPSE RATES
CONTINUE TO REMAIN FAVORABLE FOR ELEVATED CONVECTION...SO WILL
KEEP MENTION OF THUNDER IN THE FORECAST. HIGH PRESSURE WILL BECOME
MORE DOMINANT MONDAY NIGHT RESULTING IN RAIN FREE CONDITIONS
THROUGH FRIDAY.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
SHORTWAVE MOVING NW OF THE AREA THIS AFTERNOON WITH A COLD FRONT
APPROACHING FROM THE WEST WILL BRING FAIRLY WIDESPREAD SHOWERS AND
THUNDERSTORMS TO BOTH TERMINALS. TRIED TO TIME HEAVIEST SHRA/TSRA
IN 18Z TAFS. A BAND OF CONVECTION SHOULD MOVE THROUGH SAV THROUGH
19Z AFTER WHICH MORE STRATIFORM/EMBEDDED CONVECTIVE SHOWERS SHOULD
OCCUR. HARDER TO TELL WHAT WILL MAKE IT ALL THE WAY TO CHS GIVEN
THE LATEST RADAR TRENDS...BUT WE SHOULD AT LEAST SEE INCREASING
SHOWERS WITH A FEW THUNDERSTORMS BY 21Z.

PRECIP WILL SLOWLY DECREASE IN COVERAGE AND INTENSITY LATE THIS
EVENING THROUGH EARLY SUN MORNING. WE ARE THINKING THE MODEL SUITE
IS ABOUT 3 HRS TOO SLOW WITH THE FROPA AS OFTEN OCCURS WITH ACTIVE
FRONTS. THUS WE SHOW THE WIND SHIFT AND CLEARING AROUND 09Z AT
BOTH TERMINALS.

EXTENDED AVIATION OUTLOOK...OCCASIONAL MVFR OR LOWER CONDITIONS
POSSIBLE SUNDAY NIGHT AND MONDAY AS A WAVE OF LOW PRESSURE PASSES
SOUTH OF THE AREA. VFR CONDITIONS SHOULD THEN PREVAIL TUESDAY AND
WEDNESDAY.

&&

.MARINE...
STRONG PERSISTENCE FORECAST TODAY WITH LOW LEVEL JET INCREASING
FLOW THIS MORNING OVER THE WARMER OUTER WATERS AND GULF STREAM
AND DIMINISHING MIXING PROFILES OVER NEAR SHORE WATERS. THE EXCEPTION
WILL BE ALONG THE CHARLESTON COUNTY COAST WITH THE RESULTANT WINDS
CREATING STRONG THERMAL GRADIENTS...THUS ENHANCING THE POTENTIAL
FOR SCA CONDITIONS IN THE HARBOR AND INTRACOASTAL.

STRONGER LOW LEVEL SW JETTING WILL SHIFT TO THE OFFSHORE WATERS
BY LATER TONIGHT AND WE INCREASED SEAS IN OUR NRN MARINE LEG
SOMEWHAT BUT HIGHEST SEAS NEARING 10 FT POSSIBLY OUT NEAR THE
EDISTO BUOY.

A COLD FRONT WILL PUSH EASTWARD THROUGH THE WATERS SUNDAY. A WEAK
AREA OF LOW PRESSURE WILL PASS JUST SOUTH OF THE REGION SUNDAY NIGHT
AND MONDAY. HIGH PRESSURE WILL THEN BUILD FROM THE NORTH MONDAY
NIGHT AND WILL REMAIN THE DOMINANT WEATHER FEATURE THROUGH
WEDNESDAY. WILL NEED TO KEEP SCA/S GOING FOR THE NORTHERN LEG OF THE
SOUTH CAROLINA NEARSHORE WATERS AND THE OUTER GEORGIA WATERS THROUGH
SUNDAY MORNING DUE TO SEAS. CONDITIONS ARE THEN EXPECTED TO DROP
BELOW SCA LEVELS THROUGH SUNDAY NIGHT. SMALL CRAFT CONDITIONS WILL
LIKELY RETURN TO PORTIONS OF THE WATERS MONDAY AS GRADIENT PINCHES
DUE TO THE AREA OF LOW PRESSURE PASSING BY TO THE SOUTH OF THE
REGION AND HIGH PRESSURE BUILDING IN FROM THE NORTH. SMALL CRAFT
CONDITIONS MAY PERSIST THROUGH WEDNESDAY ACROSS THE OUTER GEORGIA
WATERS DUE TO FAVORABLE NORTHEAST FETCH.

RIP CURRENTS...ANOTHER MODERATE RISK OF RIP CURRENTS TODAY DUE TO
STRONG ONSHORE WINDS AND AN APPROACHING NEW MOON.
