AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1235 PM EDT FRI AUG 12 2011

...LOCALLY HEAVY RAINS AND A RISK FOR FLOODING TODAY...

.SYNOPSIS...
A WEAK TROUGH OF LOW PRESSURE WILL REMAIN OVER THE SOUTHEAST STATES
INTO THE UPCOMING WEEKEND. A COLD FRONT WILL APPROACH THE AREA FROM
THE WEST SUNDAY AND MOVE THROUGH THE REGION SUNDAY NIGHT. HIGH
PRESSURE WILL THEN REBUILD OVER THE AREA THROUGH MUCH OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
CONVECTION IS EVOLVING AS EXPECTED WITH A CLUSTER OF TSTMS
STEADILY EXPANDING ACROSS THE CHARLESTON TRI-COUNTY AREA AND
COLLETON COUNTY. SATELLITE SHOWS WHAT APPEARS TO BE AN OUTFLOW
BOUNDARY LURKING FROM NEAR WALTERBORO THROUGH ALLENDALE COUNTY.
CONVECTION MAY BACK BUILD ALONG THIS SOON. HAVE ADJUSTED POPS UP
IN THIS AREA FOR THE NEXT FEW HOURS.

DEWPOINTS ARE HOLDING IN THE UPPER 70S/LOWER 80S ALONG THE
SOUTHERN SOUTH CAROLINA COAST WHICH IS HELPING TO PUSH HEAT
INDICES NEAR 105 IN SOME AREAS. DO NOT ANTICIPATE THIS TO LAST TOO
LONG AS CONVECTION EXPANDS...BUT MUCH OF BEAUFORT COUNTY AND
COASTAL JASPER COUNTIES COULD SEE 2-3 HOURS OF 105-106 PRIOR TO
CONVECTION. WILL HOLD OFF ON THE ISSUANCE OF A HEAT ADVISORY FOR
THIS AREA.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/...
CONVERGENCE SHOULD WANE DURING THE EVENING WITH CONVECTION LIKELY
TO ROLL THROUGH MUCH OF THE FORECAST AREA IN GEORGIA PRIOR TO
SUNSET. A LATE NIGHT SHORT WAVE LOOKS FAIRLY FORMIDABLE AND WILL
LIKELY REDEVELOP SOME CONVECTIVE RAINS IN SE SOUTH CAROLINA AFTER
MIDNIGHT AND WE HAVE KEPT SOME CHANCE POPS GOING ALL NIGHT IN
THE CHARLESTON TRI-COUNTY AREA. INLAND SE GEORGIA SHOULD BE DRY
AFTER MID EVENING WITH SOME ISOLATED CONVECTION ALONG COASTAL
GEORGIA WITH THE LAND BREEZE CONVERGENCE AND THE TAIL OF THE
MID LEVEL SHORT WAVE MOVING IN. THE MAIN THREAT WILL BE SOME
HEAVY DOWNPOURS POSSIBLE OVERNIGHT ALONG THE COAST.

SATURDAY...LATEST MODEL SOLUTIONS SHOW A WEAK SURFACE BOUNDARY
LINGERING OVER NORTHERN ZONES SERVING AS A FOCUS FOR LOW LEVEL
CONVERGENCE/ISENTROPIC ASCENT AND DEEP MOIST CONVECTION THROUGH
THE MORNING HOURS...SO HAVE CARRIED SLIGHT CHANCE/LOW CHANCE POPS
SATURDAY MORNING HERE. BY AFTERNOON...THE BOUNDARY SHOULD WEAKEN
OR DISSIPATE DUE TO DAYTIME HEATING AND THE SEA BREEZE PUSH.
HIGHEST RAIN PROBABILITIES THEN APPEAR TO FOCUS INLAND AWAY FROM
THE IMMEDIATE COAST AND PARTICULARLY ACROSS SOUTHEAST GEORGIA
WHERE BEST SURFACE HEATING IS ANTICIPATED. WILL CARRY SLIGHT
CHANCE/LOW CHANCE POPS THROUGH THE AFTERNOON HOURS...WITH HIGHEST
PROBABILITIES IN LOCATIONS MENTIONED ABOVE. HIGHS ARE EXPECTED TO
TOP OUT AROUND 90 TO THE LOWER 90S NORTH AND IN THE LOWER TO
MIDDLE 90S SOUTH.

SATURDAY NIGHT...ANY LINGERING SHOWER/THUNDERSTORM ACTIVITY
SHOULD DIMINISH BY MIDNIGHT. RAIN FREE CONDITIONS THEN ANTICIPATED
THROUGH DAYBREAK SUNDAY AS THE DEEPEST MOISTURE AND STRONGEST
FORCING FOR ASCENT IN ASSOCIATION WITH THE APPROACHING COLD FRONT
REMAIN WELL WEST OF THE AREA. LOW TEMPERATURES SHOULD BOTTOM OUT
IN THE LOW TO MID 70S.

SUNDAY AND SUNDAY NIGHT...MODEL SOLUTIONS REMAIN IN GOOD
AGREEMENT SHOWING A COLD FRONT APPROACHING FROM THE WEST DURING
THE DAY THEN MOVING THROUGH THE REGION PRIOR TO DAYBREAK MONDAY.
THE COMBINATION OF DEEP MOISTURE...IMPRESSIVE DYNAMIC FORCING FOR
THIS TIME OF YEAR...AND THE AFTERNOON SEA BREEZE SHOULD RESULT IN
FAIRLY GOOD COVERAGE OF SHOWERS/THUNDERSTORMS ACROSS THE AREA.
THEREFORE...WILL CONTINUE WITH THE HIGH CHANCE POPS AREA WIDE.
WILL CONTINUE TO MENTION THE POTENTIAL FOR SEVERE WEATHER IN THE
HAZARDOUS WEATHER OUTLOOK AS WELL...WITH AN UNSEASONABLY STRONG
COLD FRONT AND DEEP UPPER LEVEL TROUGH MOVING THROUGH THE REGION
AND INTO A MODERATELY UNSTABLE AIRMASS. THE MAIN HAZARDS APPEAR TO
BE DAMAGING STRAIGHT LINE WINDS AND MARGINALLY SEVERE HAIL. HIGH
TEMPERATURES ARE EXPECTED TO TOP OUT IN THE LOW TO MID 90S.

EXPECT SHOWERS AND THUNDERSTORMS TO GRADUALLY DIMINISH FROM WEST TO
EAST SUNDAY NIGHT...BUT WILL CARRY RAIN CHANCES ALL AREAS THROUGH
THE NIGHT TO ACCOUNT FOR TIMING DIFFERENCES. LOW TEMPERATURES SHOULD
BOTTOM OUT IN THE LOW TO MID 70S.

MONDAY...GUIDANCE AGREES THAT THE DEEPEST MOISTURE AND STRONGEST
FORCING FOR ASCENT WILL HAVE SHIFTED OFFSHORE PRIOR TO
DAYBREAK...SO WILL KEEP THE FORECAST RAIN FREE. EXPECT
TEMPERATURES TO TOP OUT IN THE LOW TO MID 90S...BUT WITH LOWER
HUMIDITY VALUES IT WILL LIKELY FEEL COOLER THAN IT HAS OVER THE
PAST SEVERAL WEEKS.

&&

.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
MODEL SOLUTIONS ARE IN GOOD AGREEMENT SHOWING HIGH PRESSURE AND A
DRIER AIRMASS BUILDING OVER THE SOUTHEAST STATES THROUGH MUCH OF
NEXT WEEK. AS A RESULT...WE CONTINUE TO EXPECT A DRY PERIOD OVER
SOUTHERN SOUTH CAROLINA AND SOUTHEAST GEORGIA...AND WILL KEEP THE
FORECAST RAIN FREE AT THIS TIME. TEMPERATURES ARE EXPECTED TO RUN
NEAR TO SLIGHTLY ABOVE NORMAL...ALTHOUGH LOWER HUMIDITY LEVELS WILL
MAKE IT FEEL QUITE A BIT MORE COMFORTABLE THAN THE PAST SEVERAL
WEEKS.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
KCHS...SHOWER AND TSTM CHANCES WILL INCREASE LATER THIS MORNING
AND ESPECIALLY THIS AFTERNOON AS THE SEA BREEZE GETS GOING AND ATLC
MOISTURE CONVERGES ALONG BOUNDARIES. WE CONTINUE TO TREND WITH
SCATTERED CB. RADAR TRENDS WILL EVENTUALLY DICTATE ANY INCLUSIONS OF
TSRA AND TIMING TRENDS AS THE DAY WEARS ON.

MODELS SUGGEST ATLC MOISTURE CONVERGENCE AND AN UPPER SHORT WAVE
WILL ENHANCE RAINS SOMEWHERE ALONG THE CENTRAL OR UPPER SOUTH
CAROLINA COAST AFTER MIDNIGHT TONIGHT. LOWER CIGS AND VSBYS POSSIBLE
IF THIS BAND SETS UP THROUGH THE CHARLESTON TRI-COUNTY.

KSAV...QUIET CONDITIONS/VFR WEATHER SHOULD PERSIST UNTIL AFTERNOON
CONVECTION BECOMES SCATTERED TO THE N AND POTENTIALLY WORKS S OVER
THE REGION THIS AFTERNOON. WE CONTINUE TO TREND BY MAINTAINING CB
INTO THE TAF. TONIGHT...GENERALLY VFR CONDITIONS SHOULD PREVAIL
BUT THERE IS A CHANCE FOR PATCHY MVFR VSBYS TOWARD 12Z/13.

EXTENDED AVIATION OUTLOOK...SCATTERED SHOWERS AND THUNDERSTORMS MAY
BRIEFLY REDUCE VSBYS AND/OR CIGS SATURDAY THROUGH SUNDAY...PRIMARILY
DURING THE AFTERNOON/EVENING HOURS. OTHERWISE VFR CONDITIONS SHOULD
PREVAIL.

&&

.MARINE...
COOLER DRIER AIR OVER THE MID ATLC REGION IS FORECAST TO INCITE
A WEAK WEDGE LIKE PATTERN OVER THE WATERS TODAY AND TONIGHT WITH
ONSHORE FLOW DEVELOPING. SPEEDS NOT EXPECTED TO TOP 15 KT BUT
WE SHOULD SEE A SUBTLE INCREASE IN SEAS FROM 1 FT AT DAYBREAK
TO CLOSER TO 2 FT BY LATE TODAY AND A SOLID 2 FT TONIGHT...
PERHAPS 2 TO 3 FT WELL OFF THE COAST.

SATURDAY THROUGH WEDNESDAY...A WEAK TROUGH OF LOW PRESSURE WILL
REMAIN OVER THE SOUTHEAST STATES ON SATURDAY. A COLD FRONT WILL
APPROACH THE AREA FROM THE WEST ON SUNDAY AND MOVE THROUGH THE
WATERS SUNDAY NIGHT. HIGH PRESSURE WILL THEN REBUILD OVER THE AREA
EARLY NEXT WEEK. OVERALL THE STRONGEST WINDS IN THE COASTAL WATERS
WILL BE AT NIGHT WITH NOCTURNAL SURGING AND ALONG THE COAST DURING
THE AFTERNOON/EVENING WITH THE SEABREEZE. WE DO EXPECT AN ENHANCED
SURGE SUNDAY AFTERNOON THROUGH SUNDAY NIGHT ASSOCIATED WITH THE COLD
FRONTAL PASSAGE. WIND SPEEDS COULD APPROACH SMALL CRAFT ADVISORY
LEVELS FOR PORTIONS OF THE WATERS DURING THIS PERIOD...BUT FOR NOW
WE HAVE KEPT WINDS JUST BELOW.
