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 Sep 13, 3:27 PM EDT, 15 minutes earlier.

Area forecast discussion, Sep 13, 3:27 PM EDT, 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
327 PM EDT THU SEP 13 2007

.SYNOPSIS...
A SURFACE FRONT WILL LIFT NORTH OF THE AREA TONIGHT AND FRIDAY AS
ATLANTIC HIGH PRESSURE STRENGTHENS OFF THE SOUTH CAROLINA AND
GEORGIA COAST. ATLANTIC HIGH PRESSURE WILL WEAKEN SATURDAY...
ALLOWING A COLD FRONT TO PUSH THROUGH THE REGION LATE SATURDAY OR
SATURDAY NIGHT. STRONG HIGH PRESSURE WILL THEN BUILD IN FROM THE
NORTH THROUGH THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
A NEARLY STATIONARY FRONTAL BOUNDARY EXTENDS FROM THE MOUTH OF THE
SOUTH SANTEE RIVER WSW ACROSS ALLENDALE COUNTY. NUMEROUS SHOWERS AND
SCATTERED THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON IN THE
MODERATELY UNSTABLE ATMOSPHERE SOUTH AND EAST OF THE FRONT.
PRECIPITABLE WATERS VALUES OF 2 TO 2.25 INCHES...THETA-E
RIDGING...SLOW STORM MOTIONS AND CELL MERGERS WILL BRING THE
POTENTIAL FOR HEAVY RAINFALL AND LOCALIZED FLOODING TO THE AREA.
IN ADDITION...EXCESSIVE CLOUD TO GROUND LIGHTNING WILL OCCUR AT
TIMES AND EVEN A FEW STRONG WINDS GUSTS ARE POSSIBLE WITH THE
LARGER STORMS.

THE FRONTAL BOUNDARY WILL BEGIN TO LIFT NORTH AS A WARM FRONT
TONIGHT AS ATLANTIC HIGH PRESSURE STRENGTHENS AND HUMBERTO MOVES
NORTHEAST ACROSS THE LOWER MISSISSIPPI VALLEY. CONVECTION WILL
DECREASE IN COVERAGE LATER THIS EVENING AND EXPECT DRY CONDITIONS
OVER THE LANDMASS OVERNIGHT AS THE FOCUS FOR CONVECTION SHIFTS
OFFSHORE.

THERE MAY BE SOME BREAKS IN THE CLOUD COVER LATE THIS EVENING INTO
THE OVERNIGHT HOURS...BUT EXPECT PATCHY FOG AND LOW STRATUS TO
DEVELOP LATE TONIGHT DUE TO THE MOIST LOW LEVEL CONDITIONS AND
LIGHT BOUNDARY LAYER WINDS.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
THE FRONTAL BOUNDARY AND DEEPEST MOISTURE WILL BE ACROSS NORTHERN
GEORGIA AND THE UPSTATE OF SOUTH CAROLINA ON FRIDAY. DESPITE
THIS...PRECIPITABLE WATER VALUES WILL STILL BE VERY HIGH ACROSS
THE AREA AND LINGERING OUTFLOW BOUNDARIES AND DIFFERENTIAL HEATING
BOUNDARIES COULD ALL ACT AS FOCI FOR CONVECTION. DURING THE
AFTERNOON/EARLY EVENING HOURS...EXPECT SCATTERED TO NUMEROUS
SHOWERS AND THUNDERSTORMS WITH THE BEST COVERAGE OF PRECIPITATION
ACROSS NORTHWEST PORTIONS OF THE FORECAST AREA...CLOSEST TO THE
DEEPER MOISTURE.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
DEEP MOISTURE OVER THE AREA AHEAD OF A COLD FRONT...ENHANCED BY THE
REMNANTS OF HURRICANE HUMBERTO...WILL ALLOW FOR PERIODS OF SHOWERS
AND TSTMS SAT. AS A RESULT...WILL BUMP POPS UP TO 50 PERCENT FOR ALL
AREAS. WITH PRECIPITABLE WATER VALUES OVER 2 INCHES AND RELATIVELY
WEAK STEERING FLOW...HEAVY RAINFALL WILL BE THE MAIN HAZARD.

A NORTH/NORTHEAST FLOW WILL DEVELOP BEHIND THE FRONT AND PERSIST
INTO THE MIDDLE OF NEXT WEEK AS A STRONG AREA OF HIGH PRES BUILDS
INTO THE NERN CONUS AND RIDGES DOWN THE ERN SEABOARD. CHANCES OF
RAINFALL DIMINISH SIGNIFICANTLY ONCE THIS OCCURS...ESPECIALLY ACROSS
OUR INLAND SC ZONES WHERE THE LEAST MOISTURE IS EXPECTED. COASTAL
AREAS...ESPECIALLY ACROSS SE GA...WILL HAVE THE BEST CHANCE OF
SEEING SOME SHOWERS MUCH OF THE PERIOD DUE TO THE BETTER MOISTURE
AND SFC CONVERGENCE OVER THAT AREA.

TEMPS WILL BE NEAR TO EVEN SLIGHTLY ABOVE NORMAL SAT BEFORE DROPPING
BELOW NORMAL SUN-WED. LOWS IN THE LOWER TO MID 60S ARE EXPECTED WELL
INLAND MON-THU.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
RECENT RADAR TRENDS SHOW SHOWER AND SCATTERED THUNDERSTORM
DEVELOPMENT ACROSS THE AREA. THIS MAY LEAD TO MVFR CONDITIONS
THIS AFTERNOON FOR BOTH THE CHS AND SAV TERMINALS. EXPECT THE BULK
OF THE ACTIVITY TO END IN THE EVENING HOURS. WINDS ARE EXPECTED TO
BECOME LIGHT AND VARIABLE AT BOTH TERMINALS TONIGHT. DESPITE CLOUD
COVER...A MOIST SFC SHOULD ALLOW FOR REDUCED VSBYS TO MVFR
CONDITIONS...WITH THE LOWEST VSBYS EXPECTED AT THE SAV TERMINAL.
SOUNDINGS ALSO SUGGEST MVFR CIGS AND FSI VALUES IN THE LOW 20S.

EXPECT WINDS TO BECOME SOUTHERLY AT BOTH TERMINALS TOMORROW
MORNING AND INCREASE IN SPEED AS THE PRESSURE GRADIENT TIGHTENS
ALONG A FRONT. SHOWERS AND THUNDERSTORMS ARE POSSIBLE LATE IN THE
TAF PERIOD BUT WERE NOT INTRODUCED DUE TO UNCERTAINTY IN TIME OF
ARRIVAL.

EXTENDED AVIATION OUTLOOK...HIGHER THAN NORMAL CHANCES OF
SHRA/TSRA INTO SAT COULD PRODUCE PERIODIC MVFR/IFR CONDITIONS AT
BOTH TERMINALS...WITH POTENTIAL FOR NIGHTTIME/EARLY MORNING FOG
AND LOW CIGS AS WELL. VFR CONDITIONS WILL GENERALLY PREVAIL SUN
THROUGH TUE.

&&

.MARINE...
ATLANTIC HIGH PRESSURE WILL CONTINUE TO INFLUENCE THE COASTAL
WATERS THROUGH FRIDAY NIGHT...WITH SOUTH-SOUTHWEST WINDS SHIFTING
WEST DURING THE LATE NIGHT/EARLY MORNING HOURS. WIND SPEEDS WILL
GENERALLY BE 15 KT OR LESS...HIGHEST NEAR SHORE DURING THE MID-
LATE AFTERNOON HOURS WITH ANY SEABREEZE DEVELOPMENT. SEAS WILL BE
3 FT OR LESS.

SATURDAY THROUGH TUESDAY...A COLD FRONT IS EXPECTED TO APPROACH THE
MARINE AREA SAT AND THEN PUSH THROUGH SAT NIGHT WITH HIGH PRES
BUILDING IN FROM THE N. WITH A DECENT NE SURGE EXPECTED
SUN-TUE...SCA CONDITIONS ARE EXPECTED FOR ALL MARINE AREAS. SEAS
WILL BUILD FROM N TO S WITH THE SURGE...POSSIBLY REACHING AS HIGH AS
8 FT OVER THE OUTER GA WATERS MON AND TUE.

&&

.TIDES/COASTAL FLOODING...
A STRONG AREA OF HIGH PRES BUILDING IN FROM THE N BEGINNING SAT
NIGHT AND PERSISTING INTO THE MIDDLE OF NEXT WEEK WILL ALLOW FOR A
PROLONGED NE SURGE EVENT. THUS...THERE IS THE POTENTIAL FOR BEACH
EROSION...COASTAL FLOODING AND AN ENHANCED CHANCE FOR RIP CURRENTS.
WILL CONTINUE TO MENTION THIS THREAT IN THE HAZARDOUS WX OUTLOOK
/HWO/.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...NONE.
MARINE...NONE.
