AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1122 AM EST SAT MAR 3 2012

.SYNOPSIS...
A COLD FRONT WILL MOVE INTO THE REGION TODAY...WITH A WAVE OF LOW
PRESSURE DEVELOPING ALONG THE FRONT THIS AFTERNOON. THE LOW WILL
DEEPEN AND LIFT NORTHEAST THROUGH THE NEARBY ATLANTIC EARLY
TONIGHT...ALLOWING THE COLD FRONT TO SHIFT OFFSHORE. ISOLATED
SEVERE WEATHER COULD OCCUR AHEAD OF THE FRONT TODAY...WITH
CONSIDERABLE RAINFALL IMPACTING THE AREA EARLY TONIGHT. HIGH
PRESSURE WILL BRIEFLY BUILD BACK INTO THE REGION SUNDAY...BEFORE
ANOTHER COLD FRONT CROSSES THE AREA ON MONDAY. HIGH PRESSURE WILL
THEN RETURN TUESDAY AND DRIFT EASTWARD WEDNESDAY. A WEAK COASTAL
TROUGH COULD DEVELOP NEAR THE WATERS DURING THE MIDDLE PART OF
NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE GENERAL FORECAST REMAINS ON TRACK ACCORDING TO LATEST WEATHER
TRENDS...AND LITTLE CHANGES WERE NEEDED WITH THE MID MORNING
UPDATE.

WATER VAPOR IMAGERY CONTINUES TO SHOW A LARGE PLUME OF SUB
TROPICAL MOISTURE STREAMING FROM THE GULF OF MEXICO NORTHWARD INTO
THE SOUTHEAST AND MID ATLANTIC STATES THIS MORNING. A COLD FRONT
WILL APPROACH FROM THE NORTHWEST TODAY...WHILE A LARGE SCALE
UPPER LEVEL TROUGH STEADILY TRACKS EAST ACROSS THE CENTRAL PLAINS
REGION INTO THE MISSISSIPPI VALLEY LATE.

TWO LINES OF CONVECTION ARE CURRENTLY CONVERGING ACROSS THE
FORECAST AREA THIS MORNING...ONE LINE DESCENDING FROM INLAND
SOUTH CAROLINA AND ANOTHER STREAMING UP FROM SOUTHERN
GEORGIA/NORTHERN FLORIDA. AS THESE LINES CONTINUE TO
CONVERGE...ADDITIONAL THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG
EXISTING MESOSCALE BOUNDARIES...SPREADING PRECIPITATION ACROSS A
LARGE PORTION OF THE FORECAST AREA BY MIDDAY.

THERE IS LESS INSTABILITY AND SHEAR ACROSS THE REGION THAN SEEN
DURING THE SEVERE WEATHER OUTBREAK FRIDAY...ESPECIALLY AS THE MAIN
SURFACE LOW AND UPPER LEVEL CYCLONE HAVE PULLED FAR AWAY INTO
SOUTHEAST CANADA. THERE REMAINS CONSIDERABLE CLOUD COVER ACROSS
THE ENTIRE FORECAST AREA BY MID MORNING...WHICH WILL LIMIT DIURNAL
HEATING AND SUBSEQUENT INCREASES IN INSTABILITY. MODIFIED KCHS AND
KJAX SOUNDING FOR AFTERNOON TEMPERATURES AND DEWPOINTS ALSO
SUGGEST ONLY MARGINAL INSTABILITY AND EVEN RESIDUAL CAPPING.
MESOSCALE ANALYSIS INDICATES INSTABILITY AND SHEAR PARAMETERS
CURRENTLY MAXIMIZED ACROSS SOUTHEAST GEORGIA...AND IF THERE ARE
ANY BREAKS IN THE CLOUD COVER AS THE DAY PROGRESSES...THESE AREAS
COULD BE AT GREATEST RISK FOR ORGANIZED SEVERE DEVELOPMENT.

ALTHOUGH BEST UPPER LEVEL SUPPORT IS DISPLACED BEHIND THE COLD
FRONT AND PRE-FRONTAL TROUGH...ONGOING STRONG CONVECTION COULD
PERSIST FOR THE NEXT SEVERAL HOURS VIA BOUNDARY INTERACTIONS AND
SOME FORCING FROM A LIFTING LOW LEVEL JET. THUS THERE STILL
APPEARS TO BE A SEVERE RISK...AND WILL MAINTAIN MENTION IN THE
HAZARDOUS WEATHER OUTLOOK. IT LOOKS LIKE ANY SEVERE THREATS WOULD
BE DAMAGING STRAIGHT LINE WINDS...ALTHOUGH GIVEN SOME FAVORABLE
VORTICITY GENERATION PARAMETER VALUES AND 0-1 KM HELICITY OF 300
M2/SEC2...AN ISOLATED TORNADO CANNOT BE ENTIRELY RULED OUT. THE
HAIL RISK IS LOW GIVEN THAT THE AIR MASS WILL BE SO SATURATED.
UPON LATEST COLLABORATION WITH STORM PREDICTION CENTER...HAVE
DECIDED NOT ISSUE A WATCH FOR THE FORECAST AREA AT THIS TIME DUE
TO AFOREMENTIONED UNCERTAINTIES REGARDING AVAILABLE INSTABILITY
AND RESULTING SEVERE COVERAGE.

ENHANCED CONVERGENCE ASSOCIATED WITH A DEVELOPING WAVE OF LOW PRESSURE
ALONG THE COLD FRONT...AS WELL AS INCREASING MOISTURE...WILL SUPPORT
STEADILY RISING SHOWER/THUNDERSTORM COVERAGE THROUGH THE
AFTERNOON HOURS. WILL CONTINUE TO ADVERTISE CATEGORICAL POPS ALL
LOCATIONS TODAY. PWATS WILL BE NEAR OR GREATER THAN 2 STANDARD
DEVIATIONS ABOVE NORMAL THIS AFTERNOON...SO RAINFALL AMOUNTS WILL
BE ABOUT .75 TO 1.25 INCHES BY THE END OF THE DAY.

HOURLY TEMPERATURE TRENDS COULD BECOME QUITE DIFFICULT TO
DETERMINE DUE TO LOCAL COOLING EFFECTS FROM SHOWERS/THUNDERSTORMS.
EITHER WAY...TEMPERATURES WILL BE FAR ABOVE NORMAL AGAIN
TODAY...RISING INTO THE 70S. WILL NEED TO CAREFULLY MONITOR FOR
ANY BREAKS IN THE CLOUD COVER...AS SOME LOCATIONS COULD RISE EVEN
HIGHER THAN CURRENTLY FORECAST.

LAKE WINDS...MOST WINDS ACROSS LAKE MOULTRIE TODAY WILL HOLD AT
LESS THAN 15 OR 20 KT...BUT THERE WILL BE ENOUGH GUSTS UP NEAR 25
KT TO WARRANT A CONTINUATION OF THE LAKE WIND ADVISORY UNTIL LATE
IN THE DAY.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
A WAVE OF LOW PRESSURE WILL DEVELOP ALONG THE FRONT THIS AFTERNOON
OR EVENING...AND THIS WILL SLOW THE PROGRESSION OF THE FRONT DOWN
TO A CRAWL AS IT BECOMES PARALLEL TO THE FLOW ALOFT. AT THE SAME
TIME...STRONG LARGE SCALE FORCING WILL OVERSPREAD THE AREA WITH
THE APPROACH OF THE MID/UPPER LONG WAVE TROUGH ALOFT...ALONG WITH
THE RIGHT READ QUAD OF A 165-175 KT UPPER LEVEL JET. WHEN COMBINED
WITH FRONTOGENESIS...ELEVATED INSTABILITY AND STRENGTHENING ISENTROPIC
LIFT ON THE 295K/300K/305K SURFACES...E/RE LOOKING AT A HEAVY
RAIN EVENT TO OCCUR...ALONG WITH EMBEDDED THUNDERSTORMS FOR
TONIGHT. RAINFALL TOTALS WHEN ADDED TO THE RAIN FROM TODAY WILL
REACH AS MUCH AS 2-3 INCHES JUST ABOUT EVERYWHERE...WITH LOCALLY
HIGHER AMOUNTS POSSIBLE. HOWEVER...NO SEVERE WEATHER IS EXPECTED
DURING TONIGHT. SEE THE CLIMATE SECTION BELOW REGARDING THE
POSSIBILITY OF A FLASH FLOOD WATCH LATER TODAY.

THE LOW WILL STRENGTHEN AS IT REACHES THE GULF STREAM AROUND
MIDNIGHT...AND THEN LIFTS OUT TO THE NE LATE. THE TRAILING COLD
FRONT WILL SWING OFFSHORE AND MUCH COOLER AIR...AIDED BY
EVAPORATIONAL COOLING WITHIN THE WIDESPREAD RAINS WILL DROP TEMPS
INTO THE 40S MOST AREAS BY SUNDAY MORNING.

LAKE WINDS...WE NEED TO KEEP WATCH FOR A MARGINAL LAKE WIND
ADVISORY AGAIN LATER TONIGHT AS THE COLDER AIR WORKS ITS WAY INTO
THE AREA AND MIXES ACROSS THE WARMER WATERS OF LAKE MOULTRIE.

SUNDAY AND SUNDAY NIGHT...THE PRECIP EVENT WILL BE COMING TO AN END
IN THE MORNING AS THE DEEPENING COASTAL LOW PULLS AWAY TO THE NE.
USING THE PRECIP TREND INDICATED BY THE OPERATIONAL MODELS I HAVE
THE AREA GENERALLY PRECIP FREE BY 18Z...EXCEPT FOR A SMALL SLIVER OF
SLIGHT CHANCE POPS ACROSS THE EASTERN COASTAL WATERS. THE REMAINDER
OF THE DAY WILL FEATURE A DRYING AND CLEARING TREND IN THE WAKE OF
THE DEPARTING LOW. 850 MB WINDS REMAIN ELEVATED AND WITH THE ONSET
OF DIURNAL HEATING AND INCREASED MIXING...EXPECT A BREEZY AFTERNOON.
HIGHS WILL RANGE FROM THE UPPER 50S TO THE LOW 60S...DEPENDING ON
WHERE CLOUD COVER HANGS ON THE LONGEST. OVERNIGHT...A SURFACE HIGH
POSITIONED OVER THE WESTERN GULF WILL NOSE IN BUT ONLY BRIEFLY AHEAD
AN APPROACHING DRY COLD FRONT. THIS WILL ALLOW A CONTINUED PRESSURE
GRADIENT AND ENOUGH MIXING TO PREVENT TEMPS FROM RADIATING TOO COOL
DESPITE SUB ZERO 850 MB TEMPS. LOW WILL FALL INTO THE UPPER 30S
INLAND TO LOW 40S NEAR THE COAST.

MONDAY THROUGH TUESDAY...A REINFORCING SHORTWAVE WILL DIVE INTO THE
SOUTHERN APPALACHIANS AND QUICKLY MOVE OFF THE EAST COAST. AS IT
DOES IT WILL DRIVE A FAST MOVING CLIPPER TYPE LOW WITH A SURFACE
TROF/DRY COLD FRONT POISED TO CROSS THE FORECAST AREA ON MONDAY.
THIS WILL PROVIDE YET ANOTHER BREEZY AFTERNOON ON MONDAY WITH
COMPRESSIONAL WARMING IMMEDIATELY AHEAD OF THE FRONT. HIGHS ON
MONDAY WILL BE NEAR OR JUST BELOW NORMAL. THEN...ANOTHER SHOT OF
COLD ADVECTION BEHIND THE FRONT WILL RESULT IN HIGHS ON TUESDAY A
GOOD 5-7 DEGREES BELOW NORMAL AS HIGH PRESSURE BUILDS IN NE OF THE
AREA.

&&

.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
THE OVERALL THINKING FOR THE LONG TERM PERIOD HAS CHANGED VERY
LITTLE. THE MID/UPPER LEVEL PATTERN WILL BECOME INCREASINGLY RIDGE
LIKE OUT AHEAD OF CLOSED LOW THAT MOVES INTO THE SOUTHERN PLAINS
LATE IN THE WEEK. AT THE SURFACE HIGH PRESSURE WILL BE THE PRIMARY
WEATHER FEATURE THOUGH THE HIGH CENTER WILL GRADUALLY DRIFT EASTWARD
OVER THE ATLANTIC THROUGH FRIDAY. THE MODELS DO HINT AT POSSIBLE
COASTAL TROF DEVELOPMENT ALONG THE SE COAST...AND I HAVE CONTINUED
TO HANDLE THIS WITH SLIGHT CHANCE POPS FOR PORTIONS OF THE ATLANTIC
COASTAL WATERS. VERY LATE IN THE PERIOD...MODELS BEGIN TO DIVERGE
WITH THE HANDLING OF AN APPROACHING SYSTEM ASSOCIATED WITH THE
AFOREMENTIONED CLOSED UPPER LOW. MODEL SOLUTIONS VARY FROM THE
POTENTIAL FOR A COLD AIR DAMMING EVENT EARLY IN THE WEEKEND TO YET
ANOTHER STRONG COLD FRONTAL PASSAGE. AS SUCH THE FORECAST CONFIDENCE
DECREASES FROM FRIDAY ONWARD. OVERALL...TEMPERATURES FEATURE A
MODERATING TREND WITH LOW 70S EXPECTED BY WEDNESDAY AND THURSDAY.

&&

.AVIATION /16Z SATURDAY THROUGH WEDNESDAY/...
SHOWERS AND THUNDERSTORMS WILL CONTINUE TO MAKE A RUN FOR BOTH
TERMINALS THROUGH THE AFTERNOON...WHILE CONVECTIVE WIND GUSTS ARE
POSSIBLE WITHIN ANY SHOWERS AND THUNDERSTORMS. MVFR OR LOWER
CONDITIONS ARE POSSIBLE AT ANY TIME THAT CONVECTION IS IMPACTING
THE TERMINALS...THUS AMENDMENTS WILL LIKELY BE NEEDED. A WAVE OF
LOW PRESSURE WILL RIDE NORTHEAST ALONG THE FRONT LATE TODAY AND
EARLY TONIGHT...SLOWING THE PROGRESSION OF THE FRONT TO THE
SOUTHEAST. THIS ALLOWS FOR STEADY RAINFALL TO DEVELOP.

GUSTY SOUTHWEST SURFACE WINDS EXPECTED THIS AFTERNOON...BEFORE
EVENTUALLY VEERING TO NORTH IN WAKE OF THE SURFACE LOW AND COLD
FRONT TONIGHT. AS COLD ADVECTION DEVELOPS BEHIND THESE FEATURES
WE/RE LOOKING AT GUSTY SURFACE WINDS AND/OR LOW LEVEL WIND SHEAR
TO AGAIN OCCUR THE LAST 4-6 HOURS OF THE 12Z TAF CYCLE.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL RETURN TO THE AREA
SUNDAY AFTERNOON AND WILL CONTINUE INTO THE MIDDLE OF NEXT WEEK.

&&

.MARINE...
ALTHOUGH WARM ADVECTION IN ADVANCE OF THE COLD FRONT IS SUPPRESSING
WIND POTENTIAL OVER THE WATERS...A TIGHTENING PRESSURE GRADIENT
AS THE FRONT DRAWS CLOSER TODAY WILL ALLOW FOR MARGINAL SMALL
CRAFT ADVISORY CONDITIONS TO POSSIBLY IMPACT ALL WATERS THROUGH
THE AFTERNOON...WITH THE EXCEPTION FOR THE NEARSHORE GEORGIA
WATERS.

A WAVE OF LOW PRESSURE DEVELOPING ON THE FRONT THIS AFTERNOON AND
EVENING WILL CREATE A VERY DIFFICULT WIND FORECAST...AS THE
PRESSURE PATTERN RELAXES CONSIDERABLY AS THE WAVE RIDES OVER OR
NEAR THE WATERS. EVEN THOUGH ANY SLIGHT DEVIATION IN THE TRACK OF
THE LOW WILL CAUSE SIGNIFICANT WIND CHANGES THAN CURRENTLY IN THE
FORECAST...IT DOES LOOK LIKE CONDITIONS WILL FALL BELOW ANY ADVISORY
CONDITIONS FOR AT LEAST 6-12 HOURS FROM MID AFTERNOON UNTIL AROUND
MIDNIGHT ACROSS THE SOUTH CAROLINA WATERS. THUS...HESITANT TO CARRY
THE ONGOING ADVISORIES ANY LONGER THAN 5 PM.

COLD ADVECTION IN WAKE OF THE DEPARTING LOW AND COLD FRONT LATER
TONIGHT WILL ALLOW FOR SMALL CRAFT ADVISORY CONDITIONS TO
RETURN...AND HEADLINES WILL AGAIN BE REQUIRED. THE AMZ374 WATERS
LOOK TO REMAIN FAR ENOUGH REMOVED FROM THE TRACK OF THE LOW WHERE
THEIR GRADIENT REMAINS STRONG ENOUGH FOR SCA/S TO CONTINUE FROM
TODAY INTO TONIGHT. BUT THAT COULD TRANSITION OVER TO GALES LATE
TONIGHT WITH THE COLD ADVECTION MIXING OF 50-60 KT GEOSTROPHIC
WINDS. A GALE WATCH HAS THEREFORE BEEN ISSUED AFTER 09Z SUNDAY.

SUNDAY THROUGH WEDNESDAY...A SURFACE LOW WILL PULL AWAY FROM THE
AREA TO THE NORTHEAST SUNDAY MORNING AND A TIGHT PRESSURE GRADIENT
WILL BE IN PLACE ACROSS THE LOCAL WATERS. THIS WILL LEAD TO
STRENGTHENING NW FLOW AND HAZARDOUS CONDITIONS FOR MARINERS. SCA/S
WILL LIKELY BE NEEDED THROUGH THE DAY ON SUNDAY AND CONFIDENCE HAS
INCREASED SUFFICIENTLY TO HOIST A GALE WATCH FOR THE OUTER GA WATERS
SUNDAY MORNING. THIS IS WHEN THE BEST LOW LEVEL JETTING WILL MOVE
ACROSS THE AREA IN THE COLD ADVECTION BEHIND THE DEPARTING SYSTEM
AND GUSTS IN THE 35-40 KT RANGE WILL BE POSSIBLE FOR THE OUTER GA
WATERS DURING THIS TIME. WINDS AND SEAS WILL THEN REMAIN ELEVATED
THROUGH EARLY NEXT WEEK AS A COLD FRONT MOVE ACROSS ON MONDAY.
BEHIND THIS FRONT HIGH PRESSURE WILL BUILD IN WITH A DEVELOPING
PINCHED NE GRADIENT EXPECTED INTO THE MID WEEK TIME PERIOD. LOW
LEVEL SURGES DURING THIS TIME PERIOD MAY NECESSITATE SCA/S FOR
PORTIONS OF THE WATERS THROUGH THE END OF THE FORECAST PERIOD.

&&

.HYDROLOGY...
CONSIDERED THE POSSIBILITY OF A FLASH FLOOD WATCH FOR LATE TODAY
INTO TONIGHT...HOWEVER RAINFALL DEFICITS ARE 2.5 TO 3.5 INCHES
SINCE THE BEGINNING OF THE YEAR. THE LATEST FLASH FLOOD GUIDANCE
SHOWS MORE THAN 3 INCHES ARE NEEDED IN 3 HOURS...OR 4 INCHES IN 6
HOURS...OR 5 INCHES IN 12 HOURS. SINCE THESE CONDITIONS ARE NOT
ANTICIPATED TO REACH THOSE THRESHOLDS...HAVE OPTED TO HOLD OFF AT
THIS TIME ON ANY WATCH. WILL ADD MENTION TO THE HAZARDOUS WEATHER
OUTLOOK OF THE HEAVY RAINFALL POTENTIAL.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...LAKE WIND ADVISORY UNTIL 5 PM EST THIS AFTERNOON FOR SCZ045.
MARINE...SMALL CRAFT ADVISORY UNTIL 5 PM EST THIS AFTERNOON FOR AMZ330-
     350-352.
     GALE WATCH FROM LATE TONIGHT THROUGH SUNDAY MORNING FOR AMZ374.
