AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
120 AM EST MON DEC 17 2012

.SYNOPSIS...
A COLD FRONT WILL MOVE THROUGH THE AREA MONDAY NIGHT INTO EARLY
TUESDAY WITH HIGH PRESSURE RETURNING THROUGH WEDNESDAY. A STRONGER
COLD FRONT WILL THEN PUSH THROUGH THURSDAY BRINGING MUCH COOLER
WEATHER THROUGH THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
HAVE MADE ONLY MINOR TWEAKS TO CURRENT FORECAST. FOG POTENTIAL
STILL APPEARS TO BE LOW...AND HAVE EVEN REMOVED MENTIONED FROM THE
FORECAST GIVEN LATEST TRENDS/OBS AROUND THE AREA. TEMPS WILL BE
VERY MILD TONIGHT...LIKELY NOT GOING LOWER THAN UPPER 50S TO LOWER
60S MOST AREAS. LATEST RADAR LOOP SHOWS VERY LIGHT RAIN MOVING
EASTWARD TOWARD THE AREA. MODELS CONTINUE TO INDICATE A WEAKENING
OF THIS PRECIP AREA AS IT MOVES EASTWARD THIS MORNING. NOT SEEING
MUCH THUNDER POTENTIAL THROUGH THE MORNING...AND HAVE KEPT SHOWERS
AS THE DOMINANT PRECIP TYPE. KEPT INCREASING POP TREND INTO THE
CHANCE CATEGORY THIS MORNING...MAINLY INLAND/NW PORTIONS OF THE
AREA. EXTREME SOUTHEAST AREA...INCLUDING SAV...MAY SEE LITTLE/NO
PRECIP THROUGH SUNRISE.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH WEDNESDAY/...
EXPECT AN UNSETTLED START TO THE PERIOD WITH IMPROVING CONDITIONS BY
WEDNESDAY. A COLD FRONT WILL APPROACH THE AREA MONDAY BEFORE PUSHING
OFFSHORE MONDAY NIGHT INTO EARLY TUESDAY. THE MAIN CONCERN MONDAY
WILL BE THE POTENTIAL FOR STRONG TO SEVERE STORMS AS DEEP LAYER
SHEAR IS FORECAST TO BE 60 KT PLUS BUT ONCE AGAIN THE BIG QUESTION
REVOLVES AROUND THE AMOUNT OF INSTABILITY...ESPECIALLY AT THE
SURFACE. THERE SHOULD BE PLENTY OF CLOUD COVER IN PLACE WITH RAIN
POSSIBLY ONGOING TO START THE DAY...AT LEAST ACROSS NORTHERN AND
WESTERN PORTIONS OF THE FORECAST AREA. HOWEVER...THE STRONG
LOW-LEVEL JET MAY HELP COMPENSATE SOMEWHAT BY BRINGING HIGHER
DEWPOINT AIR INTO THE AREA. THE STORM PREDICTION CENTER CONTINUES TO
THINK THERE IS A SMALL RISK FOR SEVERE WEATHER SO CONDITIONS WILL
NEED TO BE MONITORED CLOSELY FOR THIS POTENTIAL. WILL CONTINUE TO
MENTION THIS THREAT IN THE HAZARDOUS WEATHER OUTLOOK.
OTHERWISE...RAIN CHANCES WILL BE HIGHEST MONDAY...ESPECIALLY INLAND
AREAS...BEFORE DIMINISHING FROM WEST TO EAST MONDAY NIGHT AS THE
FRONT PUSHES OFFSHORE. DEEPER HIGH PRESSURE WILL THEN MOVE OVER THE
AREA INTO WEDNESDAY MAKING FOR QUIETER WEATHER...ALBEIT
COOLER...ESPECIALLY OVERNIGHT LOWS.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
THE PERIOD WILL BEGIN DRY WITH SFC HIGH PRESSURE AND A MID LVL RIDGE
POSITIONED OVER THE SOUTHEASTERN UNITED STATES. TEMPS WILL GRADUALLY
MODIFY INTO THE UPPER 60S/LOWER 70S ON THURSDAY ALONG AND AHEAD OF A
DEEP TROUGH OF LOW PRESSURE SWINGING THROUGH THE CENTRAL UNITED
STATES. THE BEST CHANCES OF PRECIP WILL OCCUR WITH A STRONG COLD
FRONT ASSOCIATED WITH THE TROUGH AS IT SWEEPS THROUGH THE FORECAST
AREA SOMETIME THURSDAY AFTERNOON THROUGH EARLY FRIDAY. COLD AND DRY
HIGH PRESSURE WILL THEN FOLLOW THE FRONT...RESULTING IN TEMPS 10-15
DEGREES COOLER THAN PREVIOUS DAYS. EXPECT OVERALL TEMPS TO BE IN THE
MID/UPPER 50S THROUGH EARLY WEEKEND. OVERNIGHT TEMPS WILL LIKELY
REACH THE LOW 30S AWAY FROM COAST FRIDAY NIGHT...WITH SOME
MODIFICATION SATURDAY NIGHT.

&&

.AVIATION /06Z MONDAY THROUGH FRIDAY/...
LATEST OBSERVATIONS AND GUIDANCE INDICATING A LESS PESSIMISTIC
FORECAST AS FAR AS CIGS AND FOG POTENTIAL FOR EARLY THIS MORNING.
GIVEN SW LOW LEVEL WINDS OF 5-10 KTS EXPECTED TO PERSIST THROUGH
THIS MORNING...FOG POTENTIAL IS MUCH LOWER THAN PAST FEW MORNINGS.
GIVEN CURRENT CLOSE T/TD SPREADS...HAVE STILL INDICATED SOME MVFR
VSBYS IN LIGHT BR AFTER 09Z...BUT CONFIDENCE NOT VERY HIGH THAT
THIS WILL OCCUR. ALSO...CONFIDENCE THAT CIGS WILL DROP INTO THE
MVFR CATEGORY IS LOW FOR LATER THIS MORNING. HAVE MAINTAINED
PREVIOUS TREND OF SHOWING SOME BKN MVFR CIGS AROUND 09Z...BUT WILL
CONTINUE MONITORING LATEST TRENDS. MAY BE ABLE TO KEEP GENERALLY
VFR CONDITIONS THROUGH THE MORNING.

LOOKS LIKE BEST CHANCE FOR PRECIP WILL BE AT KCHS LATER THIS
MORNING THROUGH THIS AFTERNOON. CHANCE FOR ELEVATED THUNDERSTORMS
WILL HOLD OFF UNTIL THIS AFTERNOON. LOWER CHANCES FOR PRECIP AND
THUNDERSTORMS FOR KSAV TODAY.

EXTENDED AVIATION OUTLOOK...MVFR OR LOWER CIGS/VSBYS ARE EXPECTED
MONDAY NIGHT AS A COLD FRONT APPROACHES AND PUSHES THROUGH. VFR
CIGS/VSBYS ARE THEN EXPECTED TO RETURN BY TUESDAY AFTERNOON AND
PERSIST THROUGH WEDNESDAY NIGHT BEFORE CONDITIONS GO DOWNHILL
AGAIN THURSDAY AS A STRONGER COLD FRONT APPROACHES. BREEZY/GUSTY
CONDITIONS POSSIBLE MONDAY NIGHT INTO TUESDAY AND EVEN MORE SO
THURSDAY.

&&

.MARINE...
THE COASTAL WATERS WILL LIE UNDER THE EXTREME WESTERN FRINGE OF
THE ATLANTIC RIDGE TONIGHT...AS A QUASI-WARM FRONT FOUND OVER THE
CENTRAL SAVANNAH RIVER VALLEY LIFTS NE OVERNIGHT. THIS SYNOPTIC
SITUATION WILL ALLOW FOR SOUTH AND SW AND A SUBTLE INCREASE IN
SPEEDS WITH TIME. EVEN THOUGH THERE IS A GOOD 15-20 KT OF
GEOSTROPHIC WINDS...MUCH OF THAT WILL BE TEMPERED BY THE WARM
ADVECTION. THUS WE LOOK FOR MOST WINDS NO HIGHER THAN 10 OR 15 KT
THROUGH THE REST OF TONIGHT. WE/LL START OFF WITH MUCH OF THE
WAVE ENERGY IN THE FORM OF SWELLS EVERY 9-10 SECONDS...BUT THIS
WILL TRANSITION OVER TO A MIX OF SHORTER PERIOD WIND DRIVEN WAVES
AND SWELLS OVERNIGHT AS WIND SPEEDS CLIMB. SIGNIFICANT WAVE HEIGHT
WILL BE NO MORE THAN 3-5 FT...HIGHER AS ONE NAVIGATES FURTHER OFF
THE COAST. IN REGARDS TO THE SEA FOG POTENTIAL...CONDITIONS ARE
QUITE DIFFERENT THAN LAST NIGHT AND ARE STILL NOT FAVORABLE FOR
ITS FORMATION. ALTHOUGH THERE WILL BE A CONDUCIVE SOUTH AND SW
FETCH DEVELOPING...THE RESIDENCE TIME MAY NOT BE LONG ENOUGH. PLUS
THERE ARE CURRENTLY NO INDICATIONS OF ANY SEA FOG. WINDS OFF THE
SURFACE WILL LIKELY BE TOO STRONG AS NOTED BY THE GEOSTROPHIC WIND
FLOW AND FINALLY...THERE IS LITTLE CHANCE OF ANY STRATUS BUILDING
DOWN LIKE LAST NIGHT. THUS WE HAVE NO MORE THAN PATCHY FOG
FORMING...AND EVEN THIS MIGHT BE OVERDONE.

A COLD FRONT WILL BE APPROACHING FROM THE WEST MONDAY BEFORE
PUSHING OFFSHORE MONDAY NIGHT INTO EARLY TUESDAY. AN INCREASING
PRESSURE GRADIENT AND LOW-LEVEL JET WILL LEAD TO DETERIORATING
CONDITIONS OVER THE LOCAL COASTAL WATERS BUT IT APPEARS AS THOUGH
CONDITIONS WILL REMAIN BELOW ADVISORY LEVELS THROUGH THE
AFTERNOON...ALTHOUGH IT COULD COME CLOSE IN CHARLESTON HARBOR
WHERE IT COULD GET QUITE GUSTY ALONG THE LAND/SEA INTERFACE. THERE
COULD ALSO BE SOME SEA FOG NEAR THE COAST IN THE MORNING.
OTHERWISE...ADVISORY CONDITIONS ARE MORE LIKELY MONDAY
NIGHT...MAINLY ACROSS THE CHARLESTON COUNTY COASTAL WATERS AND
WATERS BEYOND 20 NM. SLOWLY IMPROVING CONDITIONS EXPECTED TUESDAY
AND ESPECIALLY WEDNESDAY/WEDNESDAY NIGHT AS HIGH PRESSURE MOVES
OVER THE AREA. CONDITIONS WILL THEN QUICKLY GO DOWNHILL THURSDAY
AS A STRONGER COLD FRONT APPROACHES AND MOVES THROUGH THURSDAY
NIGHT. SMALL CRAFT ADVISORIES ARE EXPECTED WITH GALES POSSIBLE
INTO FRIDAY.
