AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
327 PM EDT MON APR 20 2009

.SYNOPSIS...
A COLD FRONT WILL CROSS THE AREA TONIGHT...FOLLOWED BY A
REINFORCING COLD FRONT TUESDAY NIGHT. HIGH PRESSURE WILL THEN
BUILD OVER THE REGION AND WILL PERSIST THROUGH THE UPCOMING
WEEKEND AND INTO EARLY NEXT WEEK WITH NO SIGNIFICANT RAIN CHANCES
EXPECTED.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
SEVERE THUNDERSTORM WATCH 179 HAS BEEN ISSUED FOR ALL BUT FAR
INLAND COUNTIES...WHERE DEWPOINTS HAD DECREASED INTO THE
50S...UNTIL 10 PM EDT.

LATE MONDAY AFTERNOON...ISOLATED THUNDERSTORMS CONTINUED TO
DEVELOP AND TRACK NE ALONG A MARINE/DEWPOINT BOUNDARY OVER THE
FORECAST AREA. MEANWHILE...A COLD FRONT WAS APPROACHING
WESTERN/INLAND COUNTIES OF THE FORECAST AREA. TEMPERATURES IN THE
UPPER 70S/LOWER 80S AWAY FROM THE IMMEDIATE COAST AND DEWPOINTS
ALONG/EAST OF THE MARINE BOUNDARY IN THE LOWER TO MID 60S
CONTINUED TO SUPPORT SBCAPES AS HIGH AS 2000-3000 J/KG PER THE
LATEST SPC MESOANALYSIS...MEASURED JUST OVER 2100 J/KG BY THE
SPECIAL 18Z SOUNDING. COVERAGE/INTENSITY OF THUNDERSTORMS SHOULD
INCREASE WITHIN THIS UNSTABLE AIRMASS...AS SYNOPTIC SCALE FORCING
INCREASES AHEAD AN APPROACHING VORT AXIS/WITHIN THE DEVELOPING
RIGHT REAR QUADRANT OF A 100-120 KNOT 300-200 MB JET MAXIMUM
EMERGING FROM THE NORTHERN GULF OF MEXICO AND INTERACTS LOW LEVEL
CONVERGENCE AHEAD OF THE SYNOPTIC COLD COLD FRONT/IN THE VICINITY
OF MESOSCALE BOUNDARIES.

KINEMATIC/THERMODYNAMIC PARAMETERS MEASURED BY THE 18Z KCHS RAOB
REMAIN QUITE IMPRESSIVE FOR SEVERE WEATHER...MAINLY FOR VERY LARGE
HAIL AND DAMAGING WIND GUSTS...INTO THIS EVENING. SPECIFICALLY...THE
SOUNDING REVEALED 0-6 KM BULK SHEAR APPROACHING 55 KNOTS...LIFTED
INDICES EXCEEDING -6...700-500 MB WINDS 45-60 KNOTS...IDEAL WET
BULB ZERO HEIGHTS JUST OVER 9 KFT AND 500 MB TEMPS ALREADY -15C
ADVECTION ALL POINT TOWARD THE POTENTIAL FOR AT LEAST A FEW SEVERE
THUNDERSTORMS WITH LARGE HAIL AND DAMAGING WINDS. DEEP LAYER
SYNOPTIC SCALE HEIGHT FALLS/FORCING AHEAD OF THE APPROACHING COLD
FRONT WILL ONLY SERVE TO ENHANCE THE SEVERE POTENTIAL INTO THIS
EVENING. FURTHER...ENHANCED HELICITY NEAR THE MARINE/DEWPOINT
BOUNDARY COULD SUPPORT ISOLATED SUPERCELLS WITH A ATTENDANT LOW
TORNADO THREAT. ALL TOLD...THE FAVORABLE COMBINATION OF PARAMETERS
CONTINUES TO JUSTIFY A MENTION OF LARGE HAIL AND DAMAGING WINDS
WITHIN PUBLIC FORECASTS THROUGH THIS EVENING. DRY AIR AND
ASSOCIATED WARMING/CAPPING AT 700 MB AND DIURNAL STABILIZATION
THIS EVENING MAY LIMIT THE SCOPE OF THIS EVENING...THUS HELD POPS
NO HIGHER THAN 50 PERCENT ACROSS THE REGION. IF COVERAGE OF
CONVECTION INCREASES...UPDATES MAY BE REQUIRED THIS EVENING.

LAKE WINDS...UNTIL THE COLD FRONT PUSHES INTO THE REGION THIS
EVENING...SW WINDS WILL CONTINUE TO GUST TO AT LEAST 225 KNOTS ON
LAKE MOULTRIE. THUS...MAINTAINED THE ONGOING LAKE WIND ADVISORY
UNTIL 8 PM.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
IN THE WAKE OF INITIAL COLD FROPA...TUESDAY WILL START DRY ACROSS
THE REGION. THEN...A VIGOROUS SHORTWAVE RACING SE INTO THE LOWER
OHIO VALLEY MONDAY AFTERNOON WILL DIG THROUGH THE LONGWAVE TROUGH
POSITION AND WILL APPROACH THE REGION TUESDAY AFTERNOON. AHEAD OF
THIS FEATURE AND THE ASSOCIATED SECONDARY SURFACE COLD FRONT...12Z
MODELS DEPICT DESTABILIZATION DURING THE 18-21Z TIME FRAME. DESPITE
SURFACE DEWPOINTS IN THE MID 40S TO LOWER 50S...500 MB TEMPERATURES
FALLING TOWARD -18C TO -20C WILL SUPPORT DECREASING LIFTED
INDICES...AROUND ZERO PER THE 12Z GFS AND AS LOW AS -3 ALONG THE SC
COAST PER THE 12Z NAM. WHILE THE RELATIVELY DRY AIRMASS PREVENTS
ANYTHING HIGHER THAN SLIGHT CHANCE POPS...SYNOPTIC
FORCING/DESTABILIZATION AHEAD OF THE SHORTWAVE JUSTIFIES A MENTION
OF THUNDERSTORMS AFTER 18Z ACROSS N/W COUNTIES.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
FAIRLY GOOD MEDIUM RANGE MODEL CONSENSUS THIS PERIOD LEADS TO
HIGHER THAN NORMAL FORECAST CONFIDENCE.

TUESDAY NIGHT THROUGH THURSDAY NIGHT...RAIN CHANCES COME TO AN END
BY AROUND MIDNIGHT TUE NIGHT AS A SECONDARY COLD FRONT PUSHES
OFFSHORE IN ACCORDANCE WITH THE UPPER TROUGH AXIS. EXPECT HIGH
PRESSURE AT THE SURFACE AND ALOFT TO THEN MAINTAIN DRY BUT
UNSEASONABLY COOL WX ACROSS THE AREA THROUGH THU NIGHT.

FRIDAY THROUGH MONDAY...EXPECT A MODERATING TREND IN TEMPS/DEWPOINTS
THROUGH THE PERIOD AS THE SURFACE HIGH PRESSURE SYSTEM SHIFTS
OFFSHORE. NO SIGNIFICANT CHANCES FOR RAIN THOUGH WITH HIGH PRESSURE
ALOFT...ALTHOUGH IF UPPER HEIGHTS END UP BEING ON THE LOWER SIDE AS
SUGGESTED BY THE 12Z GFS...WE MAY SEE SOME SHOWERS/TSTMS FRI AFTN.
HOWEVER...PREFER TO MAINTAIN A DRY FORECAST FOR NOW.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
FORECAST ATTENTION FOCUSES ON CONVECTIVE TRENDS UNTIL 3-4Z.
AN UNSTABLE AIRMASS AND A SURFACE MARINE BOUNDARY/APPROACHING
UPPER TROUGH AND SURFACE COLD FRONT WILL CREATE CONDITIONS
FAVORABLE FOR SCATTERED SHOWERS/THUNDERSTORMS...WITH SOME
THUNDERSTORMS PRODUCING STRONG WINDS AND LARGE HAIL...IN THE
VICINITY OF BOTH TERMINALS UNTIL AFTER 3Z. AMENDMENTS APPEAR ALL
BUT CERTAIN AS NEAR TERM CONVECTIVE TRENDS COME INTO FOCUS.

IN THE WAKE OF COLD FROPA OVERNIGHT INTO EARLY TUESDAY...LOW LEVEL
MOISTURE MAY REMAIN SUFFICIENT TO PRODUCE MVFR OR LOWER CEILINGS
AND/OR VISIBILITIES. HOWEVER...ADVECTION OF DRIER AIR MAY OFFSET
THIS TREND...THUS OPTED NOT TO INCLUDE ANY SUB-VFR CONDITIONS
OVERNIGHT.

VFR CONDITIONS WILL PERSIST THROUGH 18Z TUESDAY. ISOLATED
SHOWERS/THUNDERSTORMS WITH BRIEF MVFR CONDITIONS MAY PUSH INTO THE
REGION LATER TUESDAY AFTERNOON INTO TUESDAY EVENING.

EXTENDED AVIATION OUTLOOK...MOSTLY VFR CONDITIONS TO PREVAIL
THROUGH FRIDAY...ALTHOUGH LATE NIGHT/EARLY MORNING FOG CHANCES MAY
RETURN BY LATE IN THE WEEK.

&&

.MARINE...
WILL MAINTAIN ONGOING SMALL CRAFT ADVISORIES FOR ALL MARINE ZONES
EXCEPT AMZ354...THROUGH THIS EVENING ACROSS NEARSHORE WATERS AND
THROUGH THE NIGHT ACROSS THE GA WATERS BEYOND 20 NM...TO ACCOUNT FOR
GUSTY S/SW WINDS AND ELEVATED SEAS IN ADVANCE OF AN APPROACHING COLD
FRONT. IN THE WAKE OF COLD FROPA TONIGHT...WINDS WILL SHIFT TO THE
W/WNW AND WILL DIMINISH BELOW SCA THRESHOLDS...ALLOWING SEAS TO
SUBSIDE ALL AREAS. AHEAD OF ANOTHER COLD FRONT TUESDAY...WINDS WILL
BACK TOWARD THE SW AND WILL INCREASE...ESPECIALLY DURING THE
AFTERNOON. EVEN SO...12Z GUIDANCE SUGGESTS THAT WINDS/SEAS WILL
REMAIN BELOW SCA THRESHOLDS ALL AREAS TUESDAY...BUT WILL CONTINUE TO
ASSESS THE POTENTIAL FOR SCA CRITERIA WIND GUSTS WITHIN THE MIXED
ENVIRONMENT AROUND CHARLESTON HARBOR TUESDAY AFTERNOON.

TUESDAY NIGHT THROUGH SATURDAY...A SECONDARY COLD FRONT WILL PUSH
THROUGH THE AREA TUE NIGHT...AND THE RESULTING COOL AIR ADVECTION
AND INCREASING LOW LEVEL WIND FIELDS WILL ALLOW FOR MARGINAL SCA
CONDITIONS ACROSS AT LEAST AMZ350-374.

WINDS AND SEAS WILL BEGIN TO COME DOWN ON WED WITH MUCH MORE
TRANQUIL CONDITIONS EXPECTED THROUGH SAT AS HIGH PRES SETTLES
ACROSS THE REGION.
