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 May 14, 4:08 PM EDT, 23 minutes earlier.

Area forecast discussion, May 14, 4:08 PM EDT, 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
408 PM EDT MON MAY 14 2012

.SYNOPSIS...
A BROAD AND WEAK AREA OF LOW PRESSURE AND A TRAILING COLD FRONT WILL
MOVE VERY SLOWLY TOWARD THE SOUTHEAST COAST THROUGH THE MIDDLE OF THE
WEEK...BEFORE SHIFTING INTO THE WESTERN ATLANTIC THURSDAY. HIGH PRESSURE
WILL THEN BUILD IN FROM THE NORTH FRIDAY THROUGH MONDAY. LOW PRESSURE
COULD FORM FAR OFFSHORE IN THE WESTERN ATLANTIC IN ASSOCIATION WITH
A CLOSED LOW ALOFT SATURDAY THROUGH MONDAY.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
POPS START CHANCE TO LIKELY MOST AREAS AS MESOSCALE BOUNDARIES
PRODUCED BY PREVIOUS MULTICELL THUNDERSTORMS INITIATE NEW
CONVECTION. INTO EARLY EVENING MOST NUMEROUS THUNDERSTORMS SHOULD
OCCUR ALONG/EAST OF INTERSTATE 95...AND NORTH/WEST OF THE
CHARLESTON TRI-COUNTY REGION.

IN THESE AREAS...CONDITIONS WILL REMAIN FAVORABLE FOR ISOLATED/
BRIEF PULSE SEVERE THUNDERSTORMS WITH DAMAGING WIND GUSTS AND
LARGE HAIL INTO EARLY EVENING.

AFTER DARK...DIURNAL STABILIZATION SHOULD TRANSLATE TO A STEADY
DECREASE IN THUNDERSTORM COVERAGE/INTENSITY. GIVEN THE DEEP LAYER
CYCLONIC FLOW REGIME IN PLACE...MAINTAINED ONGOING SLIGHT CHANCE
POPS ESPECIALLY N/E OVERNIGHT...BUT WOULD NOT BE SURPRISED IF
PRECIPITATION COMPLETELY DISSIPATES OVER LAND AFTER MIDNIGHT.

PATCHY FOG IS POSSIBLE WHERE HEAVY RAIN OCCURS...ESPECIALLY
IF/WHERE WINDS REMAIN LIGHT AND CLOUDS THIN OVERNIGHT...
BUT WILL DEFER DECISIONS REGARDING ADDING FOG TO PUBLIC FORECASTS
TO LATER SHIFTS.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
SOUTHWEST FLOW ALOFT WILL PERSIST THROUGH WEDNESDAY ACROSS THE AREA
IN ADVANCE OF AN UPPER LEVEL TROUGH. THE UPPER LEVEL TROUGH WILL
SWING THROUGH THE AREA WEDNESDAY NIGHT AND EARLY THURSDAY AND ALLOW
FOR A SURFACE COLD FRONT TO MOVE THROUGH THE AREA.

DEEP MOISTURE WITH PRECIPITABLE WATER VALUES NEAR 1.5 INCHES
TUESDAY THROUGH WEDNESDAY...COMBINED WITH SOME DAYTIME HEATING AND
UPPER LEVEL DISTURBANCES EMBEDDED IN THE SOUTHWEST FLOW ALOFT WILL
AID IN THE DEVELOPMENT OF WIDELY SCATTERED TO SCATTERED MAINLY
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS. AT THE PRESENT TIME
IS APPEARS THAT THE BEST COVERAGE WILL BE ON WEDNESDAY AND
MAINTAINED HIGHER RAIN CHANCES THEN. CANNOT RULE OUT A FEW STRONG TO
SEVERE THUNDERSTORMS EACH DAY...BUT FEEL THAT WITH SLIGHTLY COOLER
TEMPERATURES ALOFT..THAT THERE IS A SLIGHTLY BETTER CHANCE FOR
SEVERE THUNDERSTORMS ON WEDNESDAY. HIGH TEMPERATURES WILL BE
FAIRLY CLOSE TO SEASONAL NORMS...MAINLY IN THE MID 80S AWAY FROM THE
COAST.

IT LOOKS LIKE THE MID LEVEL TROUGH AND SURFACE COLD FRONT MOVE EAST
OF THE AREA BY LATE THURSDAY...ALLOWING FOR SOME DRIER AIR TO WORK
IN FROM THE NORTHWEST. CANNOT TOTALLY RULE OUT PRECIPITATION CHANCES
THURSDAY...BUT WITH THE UPPER LEVEL TROUGH EAST OF THE
AREA...LOWERED THE THREAT FOR RAIN INTO THE SLIGHT CHANCE CATEGORY
FOR MOST LOCALS...EXCEPT THE SOUTH WHERE CHANCE POPS WERE
MAINTAINED. MORE SUNSHINE ON THURSDAY BEHIND THE FRONT WILL MOSTLY
OFFSET THE COOLING BEHIND THE FRONT AND EXPECT HIGH TEMPERATURES TO
MAINLY BE IN THE LOWER TO MID 80S AWAY FROM THE COAST.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
THE FORECAST FOR THE END OF THIS WEEK INTO THE EARLY PART OF NEXT
WEEK IS STILL SOMEWHAT UP IN THE AIR...BUT CONSENSUS SUGGESTS THAT
WE MIGHT GET BY WITH A FEW DAYS WITHOUT RAINFALL.

THE TROUGH IN THE ATLANTIC WILL CLOSE OFF DURING FRIDAY...CAUSING A
SURFACE LOW TO FORM SOMEWHERE OUT NEAR 30 NORTH AND 70 WEST. THAT
LOW LOOKS TO MEANDER WELL OFFSHORE DURING AT LEAST THE
WEEKEND...BEFORE TURNING NORTH AT SOME POINT EARLY NEXT WEEK AS THE
CLOSED LOW OPENS AND LIFTS OUT. AT THE SAME TIME...STRONG HIGH
PRESSURE WILL BUILD INTO THE AREA FROM THE NORTH. LARGE SCALE
SUBSIDENCE LOOKS TO TAKE HOLD...WHILE THE BEST LOW LEVEL CONVERGENCE
REMAINS SOUTH OF THE AREA. THIS SHOULD KEEP THE AREA GENERALLY FREE
OF RAINFALL...ALTHOUGH SOME COASTAL SHOWERS COULD CERTAINLY OCCUR.

ADDITIONALLY....A TIGHTER PRESSURE GRADIENT WILL FORM AND BREEZY
CONDITIONS WILL OCCUR EACH DAY FRIDAY THROUGH SUNDAY...ESPECIALLY
OVER OUR COASTAL COUNTIES. THE DRIER AIR MASS WILL ALLOW FOR NIGHT
TIME LOWS TO FALL INTO THE UPPER 50S ACROSS INTERIORS SECTIONS EACH
NIGHT...WHILE AMPLE INSOLATION WILL BOOST DAYTIME HIGHS INTO THE
LOWER 80S EACH AFTERNOON AWAY FROM THE COAST.

&&

.AVIATION /20Z MONDAY THROUGH SATURDAY/...
THUNDERSTORMS WILL CONTINUE TO OCCASIONALLY IMPACT KCHS AND KSAV
UNTIL AT LEAST 21-22Z. EXPECT AMENDMENTS TO ADDRESS NEAR TERM
CONVECTIVE TRENDS. OTHERWISE...VFR EXPECTED OUTSIDE ANY
SHOWERS/TSTMS THROUGH AT LEAST THIS EVENING. ODDS FAVOR VFR
THROUGH THE NIGHT BUT BRIEF MVFR OR LOWER CONDITIONS COULD OCCUR
AT EITHER TERMINAL IF HEAVY RAIN OCCURS THIS AFTERNOON.

THUNDERSTORMS SHOULD REDEVELOP TUESDAY...ESPECIALLY IN THE
AFTERNOON...BUT PROB30 IS NOT YET JUSTIFIED PRIOR TO 18Z.

EXTENDED AVIATION OUTLOOK...PERIODIC MVFR OR LOWER CONDITIONS WILL BE
POSSIBLE TUESDAY PM THROUGH WEDNESDAY OR PERHAPS THURSDAY DUE TO
LOW LEVEL MOISTURE AND SCATTERED SHRA/TSRA. VFR CONDITIONS WILL
RETURN BY FRIDAY.

&&

.MARINE...
THROUGH THIS EVENING...THUNDERSTORMS COULD LOCALLY ALTER
WINDS/SEAS. OUTSIDE THUNDERSTORMS TONIGHT...THE WEAK SURFACE LOW
TO THE WEST WILL DRAW SLIGHTLY CLOSER AND S/SE WINDS WILL VEER
TOWARD THE SW. OUTSIDE THUNDERSTORMS...WINDS ARE EXPECTED TO REMAIN
AT OR BELOW 15 KTS THROUGH TONIGHT. SEAS OF 2-4 FEET WITHIN
NEARSHORE WATERS AND AS HIGH AS 5 FT BEYOND 20 NM SHOULD PREVAIL.

ALTHOUGH PERIODIC SHOWERS AND T-STORMS WILL IMPACT THE COASTAL
WATERS TUESDAY THROUGH THURSDAY...THE GENERAL WIND AND WAVE
CONDITIONS WILL REMAIN WELL BELOW ANY SCA LEVELS. THAT COULD CHANGE
LATE IN THE WEEK...WITH THE POTENTIAL FOR A DECENT PINCHING OF THE
PRESSURE GRADIENT TO OCCUR. STRONG HIGH PRESSURE WILL BUILD OUT OF
THE NE STATES THURSDAY NIGHT INTO THE WEEKEND...WHILE LOW PRESSURE
FORMS FAR OFF THE SE COAST. THE RESULTING PRESSURE DIFFERENCE
BETWEEN THESE TWO FEATURES WILL BE LARGE ENOUGH TO CAUSE WINDS AND
SEAS TO LIKELY REACH HIGH ENOUGH WHERE SCA/S WILL BE REQUIRED LATER
THIS WEEK.
