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 22, 6:53 PM EDT, 27 minutes earlier.

Area forecast discussion, May 22, 6:53 PM EDT, 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
653 PM EDT TUE MAY 22 2012

.SYNOPSIS...
A WEAK COLD FRONT WILL APPROACH FROM THE WEST TONIGHT...THEN
STALL AND GRADUALLY DISSIPATE WEDNESDAY AND THURSDAY. HIGH
PRESSURE WILL BUILD NORTH OF THE AREA THROUGH THE WEEKEND... WHILE
AN INVERTED TROUGH OF LOW PRESSURE WILL REMAIN WELL OFFSHORE IN
THE ATLANTIC.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
A CLOSED UPPER LEVEL LOW WILL LINGER OVER EASTERN TENNESSEE
AND NORTHERN GEORGIA BEFORE SHIFTING OVER THE SOUTHERN
APPALACHIANS LATER THIS EVENING AND OVERNIGHT. A POTENT SHORT WAVE
WILL CONTINUE TO ROUND THE BASE OF THE LOW/TROUGH AND MOVE ACROSS
THE AREA THIS EVENING BEFORE DEPARTING OVERNIGHT. AT THE
SURFACE...A LEE SIDE TROUGH OVER THE MIDLANDS AND EAST-CENTRAL
GEORGIA WILL GRADUALLY SHIFT EASTWARD AND OVER THE AREA THIS
EVENING.

STRONG DESTABILIZATION TOOK PLACE AS TEMPERATURES WARMED WELL INTO
THE UPPER 80S UNDER MOSTLY SUNNY SKIES THIS AFTERNOON. EARLY EVENING
MESOANALYSIS STILL DEPICTS SURFACE BASED CAPE VALUES AROUND 2000
J/KG OVER THE AREA...WITH DOWNDRAFT CAPE VALUES AS HIGH AS 800-900
J/KG AND LI/S OF -4. WHILE MID LEVEL LAPSE RATES ARE NOT OVERLY
IMPRESSIVE...LOW LEVEL LAPSE RATES ARE A RESPECTABLE 7.5 C/KM.
DESPITE ALL OF THE INSTABILITY...BULK SHEAR VALUES ARE NOT VERY
HIGH.

NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH MID-
EVENING ACROSS PARTS OF SOUTHEAST SOUTH CAROLINA AS THE SHORT WAVE
CONTINUES TO MOVE THROUGH. THE POTENTIAL FOR SEVERE THUNDERSTORMS
WILL CONTINUE THROUGH AT LEAST MID-EVENING...AND A SEVERE
THUNDERSTORM WATCH REMAINS IN EFFECT UNTIL 9 PM THIS EVENING FROM
COLLETON AND BEAUFORT COUNTIES UP THROUGH THE CHARLESTON TRI-
COUNTY AREA. LARGE HAIL AND DAMAGING WIND GUSTS CONTINUE TO BE THE
GREATEST CONCERN. ELSEWHERE...CONVECTION HAS COME TO AN END AND SKIES HAVE
CLEARED SOMEWHAT ACROSS SOUTHEAST GEORGIA AND PARTS OF SOUTHEAST
SOUTH CAROLINA NEAR THE SAVANNAH RIVER AS SUBSIDENCE DEVELOPS IN
WAKE OF THE PASSING SHORT WAVE. THE SEVERE THUNDERSTORM WATCH HAS
BEEN CANCELLED FOR THESE AREAS AS A RESULT.

ADDITIONAL CONVECTION HAS DEVELOPED OVER SOUTHWEST GEORGIA IN
ASSOCIATION WITH ANOTHER SHORT WAVE AND COULD SHIFT INTO PARTS OF
THE AREA LATE THIS EVENING AND INTO THE EARLY OVERNIGHT
HOURS...BUT BY THEN THE ATMOSPHERE SHOULD HAVE STABILIZED ENOUGH
TO LIMIT THE SEVERE THREAT. CONVECTION SHOULD THEN TAPER OFF FROM
THE SOUTHWEST OVERNIGHT. LOWS ARE FORECAST TO BE IN THE MID TO
UPPER 70S.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
THE UPPER TROUGH/CLOSED LOW WILL WEAKEN WEDNESDAY BUT THE TROUGH
WILL REMAIN IN PLACE THROUGH THURSDAY NIGHT BEFORE THE UPPER RIDGE
OF HIGH PRESSURE MOVES INTO THE AREA FROM THE WEST FRIDAY. AS FAR AS
RAIN CHANCES ARE CONCERNED...THE BEST CHANCE SHOULD BE ACROSS
SOUTHERN SOUTH CAROLINA WEDNESDAY WHERE THE DEEPER MOISTURE WILL
BE...ALTHOUGH THERE WILL LIKELY BE SOME CONVECTION FIRING ALONG THE
SEA BREEZE IN SOUTHEAST GEORGIA. SEVERE THREAT APPEARS
LIMITED...MAINLY CONFINED TO SOUTHERN SOUTH CAROLINA WHERE THE BEST
COMBINATION OF INSTABILITY/SHEAR ARE EXPECTED. JUST SLIGHT RAIN
CHANCES THURSDAY AND FRIDAY AS HEIGHTS RISE ALOFT...MAINLY DURING
THE AFTERNOON ASSOCIATED WITH THE SEA BREEZE.

TEMPERATURES THROUGH THE PERIOD LOOK TO REMAIN ABOVE NORMAL.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
FOR THE WEEKEND...I HAVE GONE WITH GFS SOLUTION INDICATING A FAIRLY
STRONG MID LEVEL RIDGE DEVELOPING NORTH AND WEST OF THE AREA. THE
LARGE SCALE SUBSIDENCE UNDERNEATH THE RIDGE SHOULD KEEP OUR CHANCES
FOR CONVECTION LOW AND THE TEMPS HIGH. I EXPECT MOST PLACES TO REACH
90 SATURDAY AND SUNDAY....EXCEPT LOCATIONS WITHIN 10 MILES OR SO OF
THE COAST WHERE THE SEA BREEZE WILL MODERATE THE TEMPS A BIT.
HOWEVER...NIGHT TIME LOWS ALONG THE BEACHES WILL STRUGGLE TO GET
BELOW 70...WITH MID 60S INLAND.

THE MID LEVEL RIDGE SINKS DOWN INTO THE AREA ON MONDAY AND BEGINS TO
WEAKEN A LITTLE...BUT NOT ENOUGH TO MAKE MUCH OF A DIFFERENCE IN THE
SENSIBLE WEATHER.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
VFR CONDITIONS ARE FORECAST THROUGH 18Z WEDNESDAY AT BOTH KCHS AND
KSAV...BUT THE TIMING AND COVERAGE OF CONVECTION THROUGH THIS
EVENING WILL BE THE GREATEST CONCERN AT THE TERMINALS.

AT KCHS...THUNDERSTORMS WILL AFFECT THE TERMINAL FROM AROUND
2330-0100Z BASED ON EARLY EVENING RADAR TRENDS. GUSTY AND ERRATIC
WINDS AND REDUCTIONS TO MVFR OR LOWER CONDITIONS ARE EXPECTED.

AT KSAV...EARLIER CONVECTION HAS SHIFTED OFFSHORE...HOWEVER
ISOLATED CONVECTION COULD SHIFT BACK INTO THE AREA LATE THIS
EVENING AND INTO THE EARLY OVERNIGHT HOURS. GIVEN A LACK OF
CONFIDENCE IN TIMING/COVERAGE OF ANY ADDITIONAL CONVECTION...WILL
LEAVE MENTION OUT OF THE FORECAST.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS TO PREVAIL THROUGH THE
WEEKEND. SMALL RISK FOR SH/TSTMS...MAINLY EACH AFTERNOON...AND
MVFR FOG/STRATUS EACH MORNING AROUND DAYBREAK.

&&

.MARINE...
A NOCTURNAL SURGE IS EXPECTED TO DEVELOP TONIGHT...BECOMING
SLIGHTLY MORE ENHANCED BY THE APPROACH OF AN UPPER LEVEL
DISTURBANCE. SOUTH-SOUTHWEST WINDS COULD INCREASE UPWARDS OF 15
KT...POSSIBLY EVEN A BIT HIGHER OVER THE OUTER GEORGIA WATERS...FOR
A PERIOD OVERNIGHT. SEAS WILL RESPOND BY BUILDING TO 3-5
FT...HIGHEST OVER THE OUTER GEORGIA WATERS.

WEDNESDAY THROUGH SUNDAY...ATLANTIC HIGH PRESSURE TO GENERALLY
PREVAIL THROUGH THU NIGHT BEFORE A LOW PRESSURE TROUGH OR CLOSED LOW
DEVELOPS SOUTHEAST OF THE AREA FRIDAY WHICH WILL LEAD TO WINDS
SHIFTING FROM THE SOUTH/SOUTHWEST TO NORTHEAST/EAST. COULD SEE
ADVISORY CONDITIONS OVER THE WEEKEND...MAINLY FOR SEAS BEYOND 20
NM.
