AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
102 PM EDT MON MAR 21 2016

.SYNOPSIS...
A COLD FRONT WILL MOVE ACROSS THE AREA TONIGHT...THEN HIGH PRESSURE
WILL BUILD OVER THE REGION AND PERSIST THROUGH LATE WEEK. A COLD
FRONT SHOULD APPROACH THE AREA LATE WEEK...FOLLOWED BY UNSETTLED
WEATHER NEXT WEEKEND.

&&

.NEAR TERM /THROUGH TONIGHT/...
TODAY...AN UPPER LEVEL TROUGH AXIS HAS ALREADY PUSHED OFFSHORE
WHILE HIGH PRESSURE AT THE SURFACE BUILDS IN FROM THE NORTHWEST
GULF COAST REGION. STRONG SUBSIDENCE AND A LACK OF DEEP MOISTURE
WILL RESULT IN A GOOD AMOUNT OF SUNSHINE TODAY. BREEZY CONDITIONS
WILL OCCUR AT TIMES THROUGH MID-AFTERNOON WITH COLD AIR ADVECTION
ALOFT. WEAK DOWNSLOPE WINDS SHOULD ADD A COUPLE OF DEGREES TO WHAT
LOW LEVEL THICKNESS VALUES WOULD SUGGEST...WITH HIGHS IN THE LOWER
60S MOST AREAS.

TONIGHT...UNDER CLEAR SKIES AND SURFACE WINDS BECOMING MAINLY
CALM RADIATIONAL COOLING WILL BE STRONG AND TEMPS SHOULD DIP INTO
THE MID 30S AT MANY INLAND AREAS BY DAWN. WE EXPANDED PATCHY FROST
MENTIONS IN OUR GRIDS BUT OPTED TO HOLD OFF ON ADVISORIES DUE TO
UNCERTAIN TEMP/DEW POINT SPREADS AND THE FACT THAT NUMERICAL
GUIDANCE HAS RUN TOO COOL AT TIMES THIS YEAR. FROST ADVISORIES FOR
SOME OR ALL OF OUR INLAND ZONES MAY EVENTUALLY BE ISSUED THIS
AFTERNOON AFTER ONE FINAL RUN OF THE NUMBERS.

&&

.SHORT TERM /TUESDAY THROUGH THURSDAY/...
TUESDAY...FAVORABLE CONDITIONS FOR FROST WILL CONTINUE INTO EARLY
MORNING HOURS WHILE HIGH PRESSURE IS CENTERED OVER THE SOUTHEASTERN
UNITED STATES. HOWEVER...EXPECT WARMER CONDITIONS TO RETURN LATE
MORNING INTO THE AFTERNOON AS A LIGHT SOUTHWEST WIND DEVELOPS ALONG
HIGH PRESSURE SLIDING TO THE SOUTHEAST. IN GENERAL...AFTERNOON HIGHS
WILL RANGE IN THE UPPER 60S TO AROUND 70 DEGREES...WARMEST IN
SOUTHEAST GEORGIA. OVERNIGHT TEMPS WILL BE CONSIDERABLY WARMER THAN
THE PREVIOUS NIGHT...IN THE MID TO UPPER 40S AWAY FROM THE COAST.

WEDNESDAY AND THURSDAY...ATLANTIC HIGH PRESSURE WILL DOMINATE THE
PATTERN UNDER A ZONAL FLOW ALOFT...RESULTING IN DRY CONDITIONS AND
SUNNY SKIES MIDWEEK. A NOTICEABLE WARMUP WILL OCCUR AS A SOUTHERLY
WIND PERSISTS BETWEEN ATLANTIC HIGH PRESSURE OFFSHORE AND A COLD
FRONT APPROACHING FROM THE WEST. IN GENERAL...HIGH TEMPS WILL RANGE
BETWEEN THE MID AND UPPER 70S WEDNESDAY...THEN UPPER 70S TO LOWER
80S ON THURSDAY. OVERNIGHT LOWS WILL RANGE IN THE LOW TO MID 50S
AWAY FROM THE COAST. A DEVELOPING SEABREEZE COULD LIMIT TEMPS A FEW
DEGREES NEAR THE COAST...ESPECIALLY IN SOUTHEAST SOUTH CAROLINA.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
HIGH PRESSURE WILL RETREAT OVER THE WESTERN ATLANTIC AS A COLD FRONT
ADVANCES TOWARD THE SOUTHEASTERN UNITED STATES THURSDAY NIGHT INTO
FRIDAY. CHANCES OF SHOWERS AND A FEW THUNDERSTORMS WILL BE POSSIBLE
DURING FROPA. EXPECT SLIGHTLY COOLER TEMPS BEHIND THE FRONT ON
FRIDAY...WITH AFTERNOON HIGHS IN THE LOWER 70S. A HIGH DEGREE OF
UNCERTAINTY EXISTS IN THE FORECAST FOR THE REMAINDER OF THE WEEKEND
AND EARLY NEXT WEEK AS MODEL CONSENSUS IS LOW IN REGARDS TO A
COMPLEX WEATHER PATTERN. HOWEVER...THE GENERAL TREND FAVORS A WETTER
PATTERN AS LOW PRESSURE DEVELOPS TO OUR SOUTHWEST AND EVENTUALLY
LIFTS NORTH AHEAD OF COLD FRONT THAT PUSHES THROUGH THE AREA SUNDAY
OR MONDAY. AT THIS TIME...CHANCES OF SHOWERS WILL REMAIN IN THE
FORECAST THROUGH THE WEEKEND. A FEW THUNDERSTORMS WILL ALSO BE
POSSIBLE...WITH BEST CHANCES IN SOUTHEAST GEORGIA. PRECIP ACTIVITY
AND CLOUD COVER SHOULD LIMIT HIGH TEMPS TO THE LOWER 70S THROUGH THE
WEEKEND. DRYER CONDITIONS SHOULD THEN FOLLOW LATE MONDAY AS HIGH
PRESSURE BUILDS OVER THE AREA BEHIND THE DEPARTING COLD FRONT.

&&

.AVIATION /17Z MONDAY THROUGH FRIDAY/...
VFR CONDITIONS ARE EXPECTED THROUGH 18Z TUESDAY AT BOTH KCHS AND
KSAV.

GUSTY WINDS AT BOTH TERMINALS WILL CONTINUE INTO THIS AFTERNOON BUT
GRADUAL DECLINES IN SURFACE WIND SPEED WILL BEGIN AROUND THE
22-01Z TIMEFRAME...LEADING INTO LIGHT AND VARIABLE WINDS
OVERNIGHT. DESPITE MOSTLY CLEAR SKIES AND LOW SURFACE
WINDS...THERE DOES NOT APPEAR TO BE SUFFICIENT MOISTURE TO PRODUCE
A SIGNIFICANT THREAT FOR VSBY RESTRICTIONS OVERNIGHT INTO TOMORROW
MORNING DUE TO FOG ALTHOUGH LOCALIZED SHALLOW PATCHES ARE POSSIBLE
AT EITHER TERMINAL.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL PREVAIL AT BOTH KCHS
AND KSAV TERMINALS THROUGH THURSDAY. FLIGHT RESTRICTIONS WILL BE
POSSIBLE THURSDAY NIGHT INTO FRIDAY AS A COLD FRONT SHIFTS THROUGH
THE AREA WITH SHOWERS AND/OR THUNDERSTORMS.

&&

.MARINE...
TODAY AND TONIGHT...EXPECT WINDS/SEAS TO IMPROVE THIS AFTERNOON
AS THE PRESSURE GRADIENT WEAKENS OVER THE WATERS AS THE SURFACE
HIGH NEARS. CHOPPY SEAS 3 TO 5 FT WITHIN 20 NM SHOULD DIMINISH TO
LESS THAN 3 FT BY LATE DAY WITH SEAS ALSO TENDING TO DIMINISH OVER
OUTER WATERS BY THIS EVENING. NW FLOW TONIGHT SHOULD MAINLY BE 15
KT OR LESS WITH SEAS 2 FT NEAR SHORE AND COMING DOWN TO 2 TO 3 FT
WELL OFFSHORE AFTER MIDNIGHT.

TUESDAY THROUGH SATURDAY...WINDS/SEAS WILL REMAIN WELL BELOW SMALL
CRAFT ADVISORY LEVELS MID WEEK AS HIGH PRESSURE CENTERED OVER THE
AREA SLIDES OFFSHORE AND BECOMES MORE ESTABLISHED OVER THE WESTERN
ATLANTIC. WINDS WILL LIKELY REMAIN AT OR BELOW 15 KTS MID WEEK...BUT
COULD INCREASE TO 15-20 KTS AHEAD OF A COLD FRONT ARRIVING THURSDAY
NIGHT INTO FRIDAY. SEAS WILL ALSO BUILD FROM 2-3 FT TO 3-5 FT AHEAD
OF THE FRONT. BY SATURDAY...A NORTH/NORTHEAST WIND WILL BE IN PLACE
BEHIND THE DEPARTING COLD FRONT...POSSIBLY CAUSING WINDS TO SURGE
AND SEAS TO BUILD IN NORTHERN WATERS THIS WEEKEND.

&&
