What forecasters said that day

The local office's own words before this flash flood 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 flash flood warning went out at Jun 29, 7:20 PM EDT, 18 minutes earlier.

Area forecast discussion, Jun 29, 7:20 PM EDT, 18 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
720 PM EDT TUE JUN 29 2010

.SYNOPSIS...
ATLANTIC HIGH PRESSURE WILL PERSIST INTO WEDNESDAY. A COLD FRONT WILL
DROP SOUTH THROUGH THE REGION LATE WEDNESDAY INTO THURSDAY. HIGH
PRESSURE WILL THEN BUILD OVER THE REGION INTO EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
THROUGH EARLY EVENING...NUMEROUS TO WIDESPREAD THUNDERSTORMS WILL
FOCUS ACROSS FAR W/INLAND COUNTIES OF THE FORECAST AREA...WHERE
BOUNDARY COLLISIONS AND CELL MERGERS WILL PRODUCE STRONG
THUNDERSTORMS WITH GUSTY WINDS...TORRENTIAL RAINFALL AND FREQUENT
LIGHTNING. AN ISOLATED THUNDERSTORM OR TWO COULD BECOME SEVERE
WITH DAMAGING WET DOWNBURSTS AND EVEN QUARTER SIZE HAIL.

LOWERED POPS MOST OTHER LOCATIONS...BELOW 15 PERCENT WITH NO
MENTION OF PRECIPITATION ALONG THE COAST THROUGH THE EVENING.

WILL CONTINUE TO ASSESS INLAND CONVECTIVE TRENDS...AS OUTFLOW FROM
MULTICELL THUNDERSTORMS COULD PUSH S/SE INTO THE FORECAST AREA
AND COULD PRODUCE ANOTHER ROUND OF CONVECTION ACROSS N/INLAND
COUNTIES LATE EVENING INTO THE OVERNIGHT. HOWEVER...MOST AVAILABLE
GUIDANCE SUGGESTS THAT INLAND CONVECTION WILL DISSIPATE BEFORE
REACHING THE FORECAST AREA.

MAINTAINED SLIGHT CHANCE POPS OVERNIGHT ACROSS COASTAL/NORTHERN
COUNTIES AND COASTAL WATERS. WILL CONTINUE TO ASSESS THIS
POTENTIAL AND WILL ADJUST FORECAST AS AS NEEDED LATER THIS EVENING.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
MADE A FEW TWEAKS TO THE POP FORECAST THROUGH FRIDAY...BUT
MAINTAINED THE OVERALL TREND AS A COLD FRONT DROPS ACROSS THE CWA.
BY WEDNESDAY MORNING EXPECT THE FRONT TO BE POSITIONED ACROSS THE
UPSTATE...AND THE FRONT WILL SLOWLY PROGRESS TOWARD THE CWA
WEDNESDAY AFTERNOON. ABUNDANT MOISTURE WILL RESIDE AHEAD OF THE
FRONT WITH PWATS WELL ABOVE 2 INCHES THROUGH THURSDAY. THIS MOISTURE
AND ENERGY PROVIDED BY SHORTWAVE ACTIVITY AHEAD OF THE BOUNDARY
SUGGEST HIGH CONFIDENCE IN THUNDERSTORM COVERAGE AHEAD OF THE FRONT
WEDNESDAY AFTERNOON. THUS HAVE MAINTAIN LIKELY POPS WEDNESDAY WITH
POPS DECREASING AFTER SUNSET. DUE TO LOSS OF DAYTIME
HEATING...EXPECT THUNDERSTORM COVERAGE TO DECREASE. HOWEVER WILL
MAINTAIN CHANCE POPS THROUGH THURSDAY MORNING AS THE FRONT
PROPAGATES SOUTHWARD.

PRECIP COVERAGE REMAINS DIFFICULT TO PIN DOWN THURSDAY AS COVERAGE
AND POSITIONING OF PRECIP WILL DEPEND HEAVILY ON THE POSITIONING OF
THE COLD FRONT. THINK THE FRONT WILL RESIDE OVER THE SOUTHERN
PORTIONS OF THE CWA AND COASTAL WATERS...RESULTING IN THE HIGHEST
CHANCE OF POPS ACROSS THOSE AREAS. RAIN CHANCES WILL DIMINISH
THURSDAY NIGHT...BUT INCLUDED SOME CHANCE POPS ACROSS THE WATERS AS
MODELS INDICATE A SECONDARY LOW DEVELOPING ACROSS THE NORTHERN WATERS
AS THE FRONT PUSHES FURTHER OFFSHORE. MUCH DRIER AIR WILL FILTER IN
BEHIND THE FRONT THURSDAY NIGHT AND FRIDAY WITH MODEL SOUNDINGS
SHOWING PWATS DROP TO LESS THAN 1.5 INCHES.

HIGH PRESSURE WILL BUILD INTO THE REGION WITH THE CWA ON THE EASTERN
SIDE OF A HIGH PRESSURE RIDGE ON FRIDAY. WILL SEE A BIT OF A COOLING
TREND BEHIND THE FRONTAL PASSAGE ON THURSDAY AND FRIDAY WITH HIGH
TEMPERATURES IN THE MID TO UPPER 80S.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
SURFACE HIGH PRESSURE WILL BUILD INTO THE REGION FROM THE NORTH
BEHIND THE DESCENDING FRONT THROUGH THE WEEKEND. AS DEEP MOISTURE
REMAINS SOUTH OF THE FORECAST AREA...THE DRIER REGIME COULD
POTENTIALLY SUPPRESS RAIN CHANCES EARLY NEXT WEEK. AS A
RESULT...HAVE INDICATED NO MORE THAN SLIGHT CHANCE POPS DURING THE
LONG TERM PERIOD. LOWER DEWPOINTS AND COOLER NORTHEAST/EAST
SURFACE FLOW WILL KEEP HEAT INDICES BELOW 100 DEGREES AND MAINTAIN
TEMPERATURES CLOSER TO SEASONAL NORMALS.

&&

.AVIATION /23Z TUESDAY THROUGH SUNDAY/...
THE POTENTIAL FOR THUNDERSTORMS HAS PASSED FOR THIS EVENING.
HOWEVER...WILL MONITOR THUNDERSTORMS WELL INLAND. OTHERWISE...VFR
CONDITIONS SHOULD PREVAIL.

EXTENDED AVIATION OUTLOOK...MVFR OR LOWER CONDITIONS ARE POSSIBLE
IN NUMEROUS SHOWERS AND THUNDERSTORMS ON WEDNESDAY...WITH MVFR OR
LOWER CEILINGS POSSIBLE WEDNESDAY NIGHT AND THURSDAY AS A COLD
FRONT DROPS THROUGH THE AREA. VFR CONDITIONS ARE THEN EXPECTED TO
PREVAIL THROUGH THE WEEKEND.

&&

.MARINE...
ATLANTIC HIGH PRESSURE WILL MAINTAIN A SOUTH TO SOUTHWEST FLOW
ACROSS THE WATERS TONIGHT...WITH GENERAL VEERING OF THE WINDS AS
THE LANDMASS COOLS OVERNIGHT. ANOTHER NOCTURNAL SURGE IS EXPECTED
TONIGHT WITH WINDS REACHING AS HIGH AS 15-20 KT AT TIMES. SEAS WILL
RANGE 2-4 FT.

A COLD FRONT WILL APPROACH THE WATERS LATE WEDNESDAY AND THURSDAY.
WINDS WILL REMAIN GENERALLY 10 TO 15 KNOTS AT BEST WEDNESDAY AND
THURSDAY...BUT EXPECT WINDS TO INCREASE FRIDAY IN THE WAKE OF THE
FRONT. DEPENDING ON THE STRENGTH OF THE SURGE...SEAS COULD ALSO
BUILD TO NEAR SCA CRITERIA LATE FRIDAY. HIGH PRESSURE WILL BUILD IN
FROM THE WEST FRIDAY THROUGH SATURDAY.

&&

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