AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
141 PM EST THU FEB 19 2015

.SYNOPSIS...
ARCTIC HIGH PRESSURE WILL BUILD IN THROUGH FRIDAY. A COASTAL TROUGH
WILL DEVELOP FRIDAY NIGHT AND SATURDAY...THEN LIFT NORTH ON SUNDAY
AHEAD OF AN APPROACHING COLD FRONT. THE COLD FRONT WILL MOVE THROUGH
LATE SUNDAY NIGHT AND MONDAY...BEFORE IT STALLS OFF THE SE COAST. A
WAVE OF LOW PRESSURE WILL DEVELOP ON THE FRONT EARLY NEXT
WEEK...THEN GIVES WAY TO COLDER CANADIAN HIGH PRESSURE BY THE MIDDLE
OF NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
ARCTIC HIGH PRESSURE CONTINUES BUILDING INTO THE AREA. WE BUMPED
HIGH TEMPS DOWN A COUPLE DEGREES FOR THE AFTERNOON GIVEN VERY SLOW
RISE IN TEMPS. MAINLY MID/UPPER 30S. NW WINDS WILL REMAIN GUSTY
TODAY WITH WIND CHILLS IN THE 20-30 DEGREE RANGE THROUGH THE
AFTERNOON. WE HAVE A PRETTY GOOD CHANCE OF BREAKING THE RECORD LOW
MAXES TODAY.

TONIGHT...HIGH PRESSURE WILL CONTINUE TO BUILD IN FROM THE
NORTHWEST AND THIS WILL CREATE LIGHTER WINDS...ALTHOUGH PROBABLY
STILL STAYING UP 5 TO 10 MPH THROUGH THE NIGHT. SOME HIGH CLOUDS
COULD SPILL INTO MAINLY SOUTHEAST GEORGIA LATE. THE STRENGTH OF
THE LOW-LEVEL COLD ADVECTION AND RADIATIONAL COOLING WILL LARGELY
DETERMINE HOW LOW TEMPS GET AS DEWPOINTS WILL BE IN THE SINGLE
DIGITS AND THUS NOT BE A LIMITING FACTOR. AT PRESENT WE ARE
FORECASTING MID TO UPPER TEENS INLAND AND ABOUT 20-25 AT THE
COAST...WARMEST IN GA. THIS SHOULD BREAK RECORD LOW TEMPS AT
KCHS...KCXM AND KSAV.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY/...
FRIDAY...ANOTHER COLD DAY IS IN STORE FOR THE FORECAST AREA AS THE
CORE OF THE TRANSIENT ARCTIC HIGH SHIFTS OVERHEAD AND REACHES THE
MID ATLANTIC COAST LATE. WE DO SEE AN INCREASE IN CLOUDS FROM OFF
THE ATLANTIC TOWARD EVENING AND SOME HIGHER LEVEL CLOUDINESS
ARRIVING FROM THE WEST IN THE AFTERNOON...AND THAT ALONG WITH THE
COLD START WILL LIMIT HOW MUCH TEMPS ARE ABLE TO REBOUND. WE/LL
STILL BE BELOW 32F UNTIL 10-11 AM SOUTH AND EAST AND EVEN AS LATE AS
12-1 PM NORTH AND WEST. AND THUS WE/LL BE FORTUNATE TO EVEN HIT THE
MID AND UPPER 30S NORTH/NW TO THE LOWER AND MIDDLE 40S SOUTH. RECORD
LOW MAX TEMPS ARE HIGHLY LIKELY. AT LEAST WINDS WILL BE SIGNIFICANT
LIGHTER THAN TODAY.

FRIDAY NIGHT...THE ARCTIC HIGH SETTLES INTO THE WESTERN ATLANTIC AS
THE MID LEVEL FLOW FLATTENS. IN RESPONSE TO THIS CHANGE IN THE
PATTERN A COASTAL TROUGH WILL FORM OUT NEAR THE WESTERN WALL OF THE
GULF STREAM. THE PROXIMITY TO THIS SURFACE FEATURE...WEAK ISENTROPIC
ASCENT AND A GREATER INFLUX OF MOISTURE WILL LEAD TO AN INCREASE IN
CLOUD COVER. MOST LIKELY ANY SHOWERS WILL STAY OVER THE OCEAN...SO
AT THIS TIME WE DON/T ANTICIPATE ANY FROZEN/FREEZING PRECIP MAKING
IT ONSHORE. A MODIFYING AIR MASS WITH AN ONSHORE SYNOPTIC FLOW AND
THE INSULATING INFLUENCES OF THE CLOUDINESS WILL LIMIT TEMPS FROM
GETTING AS COLD AS THE PREVIOUS TWO NIGHTS.

SATURDAY AND SATURDAY NIGHT...OUR PATTERN UNDERGOES SUBSTANTIAL
CHANGES AS THE ATLANTIC HIGH STRENGTHENS AND PULLS FURTHER
OFFSHORE...WHILE WARM ADVECTION DEVELOPS IN ADVANCE OF THE NEXT COLD
FRONT TAKING SHAPE IN THE OHIO AND LOWER MS VALLEYS. THE NEARBY
COASTAL TROUGH SATURDAY BECOMES MORE NEBULOUS SATURDAY NIGHT.
ISENTROPIC UPGLIDE STRENGTHENS AND COINCIDES WITH A CONTINUED FEED
OF ATLANTIC MOISTURE ON THE SW SIDE OF THE LARGE ATLANTIC
RIDGE...EVENTUALLY LEADING TO A RETURN OF SHOWERS. THE BEST CHANCES
OF WET WEATHER IS MAINLY EAST OF I-95 IN CLOSER PROXIMITY TO THE
COASTAL TROUGH AND WHERE THE BEST LOW LEVEL CONVERGENCE WILL BE
FELT. IT/LL FEEL ALMOST BALMY TO COMPARISON TO RECENT DAYS WITH
TEMPS TO CLIMB SOME 20 DEGREES IN MANY AREAS FROM MAX TEMPS FRIDAY.
A DECENT THERMAL GRADIENT WILL PREVAIL SATURDAY...LOWER AND MIDDLE
50S NORTH AND EAST TO THE LOWER AND MIDDLE 60S SOUTH. WE/LL KEEP
WATCH FOR POSSIBLE FOG DEVELOPMENT WITH THE WARMER AIR MASS ACROSS
THE COOLER GROUNDS.

SUNDAY...THE UPSTREAM COLD FRONT SLIDES ACROSS THE APPALACHIANS BUT
STARTS TO BECOME ALIGNED PARALLEL TO THE FLOW ALOFT...WHICH LIMITS
IT/S PROGRESSION TOWARD THE FORECAST ZONES. COMPRESSIONAL HEATING IN
ADVANCE OF THE FRONT AND SOLID WARM ADVECTION WILL LEAD TO WHAT MAY
FEEL ALMOST SUMMER-LIKE WHEN COMPARED TO THURSDAY AND FRIDAY. MID
LEVEL PERTURBATIONS WILL TRAVERSE THE REGION WHILE THE COASTAL
TROUGH BECOMES ILL-DEFINED OR LIFTS TO THE NORTH. THIS ALONG WITH
AMPLE MOISTURE WILL ALLOW FOR ISOLATED TO SCATTERED SHOWERS TO
OCCUR. SEA FOG COULD BECOME A CONCERN GIVEN FAVORABLE SOUTHERLY
TRAJECTORIES AND VERY HUMID AIR OVER-RIDING THE COOLER SHELF
WATERS.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
THE LARGE SCALE PATTERN REVEALS A ZONAL FLOW ALOFT INTO EARLY NEXT
WEEK THAT EVENTUALLY EVOLVES INTO MORE OF A BROAD COLD TROUGH BY MID
WEEK. THE PROGRESSION OF THE COLD FRONT WILL BE RATHER SLUGGISH
EARLY IN THE EXTENDED PERIODS GIVEN THAT THE FRONT IS STILL ORIENTED
SOMEWHAT PARALLEL TO THE FLOW ALOFT. THIS CAUSES THE FRONT TO STALL
OFF THE SE COAST EARLY NEXT WEEK...BEFORE THERE IS ENOUGH PUSH FROM
COLDER CANADIAN HIGH PRESSURE BY MID WEEK. THERE REMAIN INDICATIONS
THAT A WAVE OF LOW PRESSURE WILL FORM ALONG THE STATIONARY FRONT NOT
TOO FAR OFFSHORE...CAUSING ENOUGH FORCING/LIFT TO MAINTAIN CHANCE
POPS EARLY NEXT WEEK. THE LOW PULLS AWAY BY MID WEEK AND ALTHOUGH
COLDER AIR FILTERS IN...THE MOISTURE SHOULD BE SCOURED OUT BY THEN
TO NOT CAUSE ANY WINTER-WEATHER CONCERNS.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
VFR. GUSTY WINDS WILL IMPACT BOTH TERMINALS THROUGH LATE AFTERNOON...
PEAKING THIS AFTERNOON AROUND 25 KT.

EXTENDED AVIATION OUTLOOK...VFR WEATHER INTO SATURDAY. MVFR OR LOWER
CONDITIONS PROBABLE LATE SATURDAY INTO SUNDAY AS A COASTAL TROUGH
DEVELOPS OVER THE ATLANTIC. ADDITIONAL FLIGHT RESTRICTIONS POSSIBLE
SUNDAY NIGHT INTO MONDAY AS THE NEXT COLD FRONT MOVES INTO THE
AREA.

&&

.MARINE...
TODAY AND TONIGHT...MARINE CONDITIONS GRADUALLY IMPROVING AS THE
ARCTIC HIGH SHIFTS CLOSER TO THE WATERS AND REDUCES THE GRADIENT.
WE DROPPED THE GALE WARNING FOR THE OFFSHORE GA WATERS GIVEN THAT
WIND GUSTS AT BUOY 41004 ARE NOW BELOW 30 KT. SMALL CRAFT
ADVISORIES CONTINUE THROUGH THE AFTERNOON FOR THE NEARSHORE WATERS
AND HARBOR AND THROUGH THIS EVENING FOR THE GA OFFSHORE.

COULD SEE ANOTHER WEAK SURGE LATE TONIGHT AS HIGH PRESSURE BUILDS
CLOSER TO THE AREA BUT CONDITIONS WILL GENERALLY BE BELOW ADVISORY
LEVELS AFTER THIS EVENING.

FRIDAY THROUGH SATURDAY...STRONG ARCTIC HIGH PRESSURE FRIDAY MOVES
THROUGH THE MID-ATLANTIC REGION AND INTO THE ATLANTIC FRIDAY NIGHT
AND SATURDAY. AS THIS EVOLUTION OCCURS AN INVERTED TROUGH WILL FORM
NEAR THE WESTERN WALL OF THE GULF STREAM. WINDS WILL GRADUALLY CLOCK
AROUND FROM THE NORTH AND NE FRIDAY INTO FRIDAY NIGHT...TO THE EAST
AND SE MOST WATERS SATURDAY. WINDS AND SEAS HOWEVER WILL BE BELOW
ANY SMALL CRAFT CONDITIONS.

SATURDAY NIGHT THROUGH SUNDAY NIGHT...THE COASTAL TROUGH WEAKENS
WITH TIME AS THE ATLANTIC HIGH MOVES FURTHER OUT INTO THE ATLANTIC.
WHILE THERE IS NO CONCERNS IN REGARDS TO WINDS AND SEAS...THERE IS
AN INCREASING CONCERN FOR THE DEVELOPMENT OF SEA FOG AS A WARMER AND
HUMID AIR MASS MAKES A RETURN. THERE IS DECENT RESIDENCE TIME OVER
THE COOLER NEAR SHORE WATERS FOR THE SEA FOG TO FORM AND WE/VE
INCLUDED SUCH IN THE HAZARDOUS WEATHER OUTLOOK.

MONDAY THROUGH TUESDAY...AT SOME POINT THE NEXT COLD FRONT WILL
ARRIVE FROM THE NW...BUT IT STALLS OVER OR NEARBY THE MARINE
DISTRICT. A WAVE OF LOW PRESSURE WILL DEVELOP ON THE FRONT AS HIGH
PRESSURE BUILDS FROM THE NW. SMALL CRAFT ADVISORIES ARE POSSIBLE AS
A RESULT.
