AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
148 PM EDT THU JUN 7 2007

.SYNOPSIS...
STRONG UPPER LEVEL RIDGE OVER THE REGION THROUGH FRIDAY WILL
RETROGRADE WEST THIS WEEKEND...AS A WEAK COLD FRONT DRIFTS
SOUTHEAST AND STALLS OVER GEORGIA AND THE CAROLINAS.

&&

.NEAR TERM /THROUGH TONIGHT/...
LATEST RADAR DEPICTS SHOWERS INITIATING ALONG AND WEST OF THE
SEABREEZE THIS HOUR. A FEW ISOLATED THUNDERSTORMS ARE POSSIBLE
THROUGH THE AFTERNOON...WITH MODELS MORE CONSISTENT IN SUGGESTING
A SLIGHT CHANCE FOR THUNDERSTORMS IN THE SOUTHWESTERN COUNTIES.
FEEL THAT THOSE LOCATIONS MAY BE MORE LIKELY TO SEE MORE ORGANIZED
DEVELOPMENT IN RELATION TO AREAS TO THE NORTH AND ALONG THE COAST.
A COMPARISON OF MODEL SOUNDINGS BETWEEN THE CHARLESTON AREA AND
HINESVILLE IN LIBERTY COUNTY SUGGESTS THAT AREAS TO THE SOUTH OF
THE SAVANNAH RIVER MAY HAVE A SLIGHTLY BETTER FETCH OF HIGHER
DEWPOINT AIR OFF THE GOMEX THIS AFTERNOON. THUS...HIGHER LEVELS OF
MOISTURE AND INSTABILITY MAY BE ABLE TO MORE EFFICIENTLY TAP INTO
SEABREEZE FORCING LATE IN THE DAY. CURRENT POPS SCHEME REPRESENTS
THIS SCENARIO WELL...WITH A SLIGHT CHANCE OF THUNDERSTORMS MAINLY
WEST OF I-95 AND SOUTH OF THE SAVANNAH RIVER.

CONDITIONS THIS AFTERNOON WILL AGAIN BE HOT...WITH HIGH TEMPERATURES
EXPECTED TO REACH THE LOWER TO MID 90S AWAY FROM THE COAST. LOWS
TONIGHT WILL ONLY DROP INTO THE LOWER 70S.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
MODELS A LITTLE LESS AGGRESSIVE WITH CHANCES FOR DIURNAL CONVECTION
ON FRIDAY WITH MID LEVEL CAP HOLDING FIRM ACROSS OUR REGION. JUST
THE PRESENCE OF A WEAK LEE SIDE SURFACE TROF AND GULF/ATLANTIC
SEA BREEZE INTERACTIONS SUGGEST KEEPING ALL INLAND POPS IN THE 20
PERCENT RANGE FRI AFTN/EVENING. ON SAT...IMPROVED LOW LEVEL FORCING
AHEAD OF AN APPROACHING FRONT SHOULD ENSURE MORE CONVECTION WELL
INLAND. WE RETAINED THE PREVIOUS POP SCHEME WITH 30 POPS WEST OF I-95
AND SLIGHT CHANCE TOWARD THE COAST. INLAND DEW POINTS STILL HIGHEST
ON SAT...AND WE WILL CONTINUE TO MENTION 100-105 HEAT INDICES IN
HWO PRODUCT THIS MORNING FOR THAT TIME FRAME.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
A COOL FRONT WILL APPROACH THE AREA FROM THE NORTH SATURDAY NIGHT
AND SUNDAY. MODELS DIFFER SOMEWHAT ON THE DETAILS AND TIMING...BUT
IN GENERAL SUNDAY LOOKS LIKE THE BEST CHANCE OF CONVECTION WITH
THE FRONT IN THE AREA AND A POCKET OF UPPER LEVEL ENERGY PASSING
OVERHEAD.

THE FRONT SHOULD DRIFT SOUTH OF THE AREA AND LOSE DEFINITION BY
MONDAY WITH MAX TEMPS BACK DOWN TO SEASONABLE LEVELS EARLY NEXT
WEEK. ISOLATED AFTERNOON POPS EACH DAY PER CLIMO AS THE AMOUNT OF
DRY AIR SURGING IN FROM THE NORTH BEHIND THE FRONT IS IN QUESTION.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...SEABREEZE DEVELOPMENT
HAS SPAWNED SHOWERS ACROSS THE FORECAST AREA THIS
AFTERNOON...CONCENTRATED MOSTLY WEST OF I-95 AND SOUTH OF THE
SAVANNAH RIVER. SEVERAL SMALL SHOWERS ARE NEAR KSAV...SO HAVE
ADDED VCSH TO THE TAF FOR THE NEXT HOUR. WILL CONTINUE TO MONITOR
RADAR TRENDS TO DETERMINE WHETHER ADDITIONAL SHOWER OR
THUNDERSTORM WORDING MAY NEED TO BE ADDED FOR THE AFTERNOON HOURS.

SOUTHERLY WINDS HAVE INITIATED AT BOTH TERMINALS WITH THE SEA
BREEZE DEVELOPMENT. EXPECT WINDS SPEEDS TO BE PREVAILING AOB 12
KNOTS...BUT CANNOT RULE OUT A BRIEF GUST A FEW KNOTS HIGHER.
SCATTERED CUMULUS WILL DIMINISH AFTER SUNSET WHEN DAYTIME HEATING
AND MIXING DIMINISHES.

WINDS WILL DECREASE OVERNIGHT. SHALLOW GROUND FOG COULD BE POSSIBLE
AGAIN AT KCHS OVERNIGHT...BUT DO NOT FEEL CONFIDENT ENOUGH TO
INCLUDE IN TAFS. HAVE INSTEAD BROUGHT VSBYS DOWN TO 6 SM JUST TO
PROVIDE A HEADS UP.

EXTENDED AVIATION OUTLOOK...GENERALLY VFR UNDER HIGH PRESSURE THROUGH
FRIDAY. POSSIBLE AFTERNOON/EVENING ISOLATED SEABREEZE THUNDERSTORMS
MAY PRODUCE BRIEF MVFR OR LOWER CONDITIONS. A FRONTAL BOUNDARY
WILL APPROACH FROM THE NORTHWEST OVER THE WEEKEND AND THEN DISSIPATE
OVER THE AREA...ENHANCING THE CHANCE FOR SHOWERS/THUNDERSTORMS
WITH MVFR OR LOWER CONDITIONS.

&&

.MARINE...
RATHER TRANQUIL CONDS WILL PREVAIL OVER THE WATERS THROUGH THE
WEEKEND INTO EARLY NEXT WEEK. HIGH PRES WILL REMAIN IN CONTROL
THROUGH FRI...THEN GIVE WAY TO A SLOWLY APPROACHING FRONTAL
BOUNDARY THAT WILL STALL OVER THE AREA SUN INTO MON BEFORE LIFTING
AWAY IN FAVOR OF HIGH PRESSURE. NO SIGNIFICANT PRESSURE GRADIENTS
WILL BE CREATED FROM THIS SYSTEM...SO OUTSIDE OF POSSIBLE NIGHTLY
SURGES AND NEARSHORE SEABREEZE SURGES...WIND SPEEDS WILL GENERALLY
REMAIN AOB 15 KT. SIMILARLY... WITH NO PERSISTENT ONSHORE EXPECTED
THROUGH THE WEEKEND...SEAS WILL REMAIN AOB 4 FT.

&&

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