AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
844 PM HST FRI DEC 12 2014

.SYNOPSIS...
THE REMNANTS OF AN OLD FRONT WILL CONTINUE TO PRODUCE LIGHT RAIN
OVER WINDWARD AREAS OF THE BIG ISLAND OVERNIGHT BEFORE MOVING
SOUTH OF THE ISLANDS EARLY SATURDAY MORNING. A SHEAR LINE WILL
REACH KAUAI FROM THE NORTHWEST SATURDAY...THEN PUSH DOWN ACROSS
THE OTHER ISLANDS SATURDAY NIGHT THROUGH MONDAY...AND MOVE SOUTH
OF THE BIG ISLAND BY MONDAY EVENING. THE SHEAR LINE WILL PRODUCE
WIDESPREAD...BUT NOT VERY HEAVY RAIN. A LARGE SURFACE HIGH BEHIND
THE FRONT WILL BRING STRONG TRADE WINDS DURING THE WEEKEND. A
LARGE SWELL AND THE STRONG TRADES WILL CREATE VERY ROUGH SEAS OVER
THE WEEKEND AS WELL.

&&

.DISCUSSION...
DRY CONDITIONS PREVAIL ACROSS MOST OF THE STATE ON THIS FRIDAY
EVENING. THE EXCEPTION IS ACROSS THE WINDWARD COAST OF THE BIG
ISLAND...WHERE NUMEROUS SHOWERS AND AREAS OF LIGHT RAIN CONTINUE
ALONG THE REMNANT CLOUD BAND OF A DISSIPATED FRONTAL BOUNDARY.
SURFACE ANALYSIS DEPICTS A COLD FRONT ABOUT 200 MILES NORTHWEST OF
KAUAI...WITH A WEAKENED PRESSURE GRADIENT OVER THE MAIN HAWAIIAN
ISLANDS DUE TO THE PRESENCE OF THE FRONT TO THE NORTHWEST AND
NORTH OF THE STATE. A 1029 MB HIGH CENTERED NEAR 35N175W IS
BUILDING EASTWARD BEHIND THE FRONT. DRY AND STABLE CONDITIONS
PREVAIL ALOFT...WITH THE STATE ALONG THE NORTHWEST PERIPHERY OF A
MID LEVEL RIDGE CENTERED A COUPLE HUNDRED MILES SOUTHEAST OF THE
BIG ISLAND. THE 00Z HILO SOUNDING REFLECTED THE DEEPER MOISTURE
PRESENT IN THAT AREA ALONG THE OLD FRONT...WITH THE INVERSION UP
AROUND 8000 FEET AND PWAT OF 1.33 INCHES. MEANWHILE THE 00Z LIHUE
SOUNDING FOUND A LOWER INVERSION BASED NEAR 5000 FEET AND PWAT OF
1.11 INCHES. MIMIC-TPW SATELLITE IMAGERY DEPICTS A NARROW RIBBON
OF SOMEWHAT ELEVATED MOISTURE ALONG THE APPROACHING FRONT TO OUR
NORTHWEST...OTHERWISE A GENERALLY DRY AIRMASS PREVAILS OVER THE
REGION WITH DEEP TROPICAL MOISTURE SUPPRESSED FAR TO THE SOUTH OF
THE STATE.

IN THE NEAR TERM...EXPECT WET CONDITIONS TO CONTINUE ACROSS THE
WINDWARD BIG ISLAND THROUGH MUCH OF THE NIGHT...WITH GENERALLY
DRY CONDITIONS ELSEWHERE. INCREASING TRADES MAY START TO GENERATE
SOME SHOWERS ACROSS WINDWARD SECTIONS OF THE SMALLER ISLANDS LATE
TONIGHT. THE EXISTING FORECAST APPEARS TO BE ON TRACK...AND NO
UPDATES ARE PLANNED FOR THIS EVENING.

THE FRONT/SHEAR LINE INITIALLY TO OUR NORTHWEST WILL CONTINUE
PUSHING SOUTHEAST OVERNIGHT...REACHING KAUAI ON SATURDAY AND
THEN CONTINUING TO PUSH SOUTHEAST THROUGH THE STATE SATURDAY NIGHT
AND SUNDAY. HIGH PRESSURE BUILDING TO OUR NORTH WILL CAUSE TRADE
WINDS TO BEGIN INCREASING OVER THE STATE EVEN AHEAD OF THE ARRIVAL
OF THE SHEAR LINE...WITH WINDS INCREASING FURTHER BEHIND IT. MODEL
SOUNDINGS AND HIGH-RESOLUTION WRF MODEL PLAN VIEW OUTPUT SHOW LOW
LEVEL WINDS INCREASING ABOVE 30 KNOTS ACROSS MANY AREAS FROM LATE
SATURDAY AFTERNOON THROUGH SATURDAY NIGHT AND INTO SUNDAY. MID
LEVEL RIDGING SHOULD MAINTAIN A RELATIVELY LOW AND STRONG
INVERSION DURING MOST OF THIS TIME...ALTHOUGH THE PASSAGE OF THE
LOW LEVEL CLOUD BAND ALONG THE SHEAR LINE MAY TEMPORARILY RAISE
AND WEAKEN THE INVERSION. A LOWER/STRONGER INVERSION WOULD HELP TO
ENHANCE THE STRONG TRADE WINDS...ESPECIALLY OVER FAVORED LEEWARD
AREAS WHERE WINDS WILL ACCELERATE DOWNSLOPE. THERE REMAINS A GOOD
CHANCE THAT WIND ADVISORIES WILL BE NEEDED FOR PORTIONS OF THE
STATE DURING THE WEEKEND...AND HIGH WIND WARNINGS FOR SELECT AREAS
CANNOT BE RULED OUT. WILL FURTHER CONSIDER THE ISSUANCE OF WIND
ADVISORIES WITH THE EARLY SATURDAY MORNING FORECAST PACKAGE.

OTHERWISE...THE INCREASING TRADES WILL SQUEEZE OUT AVAILABLE
LOW LEVEL MOISTURE AGAINST THE TERRAIN DURING THE WEEKEND.
DRY/STABLE CONDITIONS ALOFT SHOULD PREVENT HEAVY DOWNPOURS...BUT
PERSISTENT LIGHTER RAINS IN THE FAVORED WINDWARD TERRAIN COULD
GENERATE SOME DECENT LONGER-TERM RAINFALL TOTALS. THE STRENGTH
OF THE TRADES WILL CARRY SHOWERS AND AREAS OF LIGHT RAIN/DRIZZLE
OVER INTO SOME LEE AREAS AS WELL...ESPECIALLY THOSE JUST TO THE
LEE OF THE HIGHER TERRAIN. A DEVELOPING UPPER LEVEL TROUGH NEAR
170W WILL GENERATE ABUNDANT HIGH CLOUDINESS OVER THE REGION
SATURDAY NIGHT THROUGH SUNDAY NIGHT...AND WOULD EXPECT A CLOUDY
DAY FOR MOST AREAS ON SUNDAY.

THE SURFACE HIGH PASSING TO OUR NORTH WILL MAINTAIN STRONG/GUSTY
TRADE WINDS THROUGH MONDAY...THEN THE TRADES WILL GRADUALLY
DECREASE TUESDAY THROUGH WEDNESDAY AS THE HIGH WEAKENS AND SHIFTS
FURTHER TO THE EAST. EXPECT A TYPICAL WINDWARD SHOWER REGIME TO
PREVAIL. THE NEXT COLD FRONT SHOULD PASS NORTH OF THE STATE WITH
LITTLE EFFECT AROUND MIDWEEK...THEN A NEW WEAKER HIGH PASSING TO
OUR NORTH SHOULD MAINTAIN MODERATE TO LOCALLY BREEZY TRADES
THROUGH NEXT FRIDAY.

&&

.AVIATION...
REMNANT MOISTURE FROM AN OLD FRONTAL BAND CONTINUES TO LINGER NEAR
THE BIG ISLAND. THIS IS HELPING TO FUEL SHOWERS WITH MVFR AND ISOL
IFR CIGS/VIS NEAR AND OVER WINDWARD BIG ISLAND...INCLUDING PHTO.
SHOWERS ARE GENERALLY LOW TOPPED...WITH TOPS BETWEEN 6 AND 9KFT.
THIS AREA OF MOISTURE IS EXPECTED TO SLOWLY SLIDE SOUTH THROUGHOUT
THE NIGHT...HOWEVER MVFR CONDITIONS ARE LIKELY TO STICK AROUND
INTO THE MORNING. AIRMET SIERRA FOR MOUNTAIN OBSCURATION IS
POSTED.

FOR MAUI MOLOKAI AND OAHU...PASSING PERIODS OF TEMPO MVFR ARE LIKELY
OVER WINDWARD AREAS TONIGHT...AS SOME OF THE REMNANT MOISTURE
LINGERS NEAR THEM.

AS OF NOW...KAUAI REMAINS FAIRLY QUIET WITH ISOL MVFR IN PASSING
CLOUDS AND SHOWERS. HOWEVER...AS A SHEAR LINE APPROACHES FROM THE
NW...AN INCREASE IN CLOUD COVER AND NORTHEASTERLY WINDS WILL START
OCCURRING...AS EARLY AS LATE TONIGHT INTO EARLY TOMORROW MORNING.
AIRMET SIERRA WILL LIKELY BE NEEDED FOR MTN OBSCURATION OVER KAUAI
AT THAT TIME. ADDITIONALLY...AIRMET TANGO FOR LOW LEVEL TURB WILL
BE POSTED. AS THE SHEARLINE MOVES THROUGH THE ISLAND CHAIN...
POTENTIAL AIRMETS WILL BE EXPANDED AS NEEDED.

&&

.MARINE...
LONG PERIOD NORTHWEST SWELL HAS BEGUN TO ARRIVE AT BUOY 51101
DURING THE LAST FEW HOURS...AND APPEARS TO BE RUNNING MORE OR
LESS ON SCHEDULE COMPARED TO WAVEWATCH GUIDANCE. THIS SWELL
SHOULD REACH KAUAI BEFORE SUNRISE THEN CONTINUE BUILDING ACROSS
THE HAWAIIAN COASTAL WATERS THROUGH SATURDAY. A HIGH SURF ADVISORY
REMAINS IN EFFECT FOR NORTH AND WEST FACING SHORES OF THE SMALLER
ISLANDS...AND WARNING LEVEL SURF APPEARS LIKELY FOR THESE AREAS
SATURDAY NIGHT INTO SUNDAY WHEN THE SWELL IS FORECAST TO PEAK.
THERE IS ALSO THE POTENTIAL FOR ADVISORY LEVEL SURF ALONG THE WEST
FACING SHORES OF THE BIG ISLAND FOR SATURDAY AFTERNOON AND
SATURDAY NIGHT.

ELSEWHERE...STRONG TRADE WINDS BUILDING ACROSS THE STATE DURING
THE WEEKEND WILL PRODUCE INCREASING SHORT-PERIOD SWELL AND SURF
ALONG EAST FACING SHORES...AND A HIGH SURF ADVISORY MAY BE NEEDED
FOR THOSE AREAS FROM SATURDAY NIGHT THROUGH MONDAY.

WITH STRONG TRADES EXPECTED DURING THE WEEKEND...A GALE WATCH
REMAINS IN EFFECT FOR THE TYPICALLY WINDIER AREAS AROUND MAUI
COUNTY AND THE BIG ISLAND. THIS MAY BE UPGRADED TO A GALE WARNING
EARLY SATURDAY...WITH A STRONG POSSIBILITY FOR PERIODS OF GALE
CONDITIONS IN THESE WATERS FROM SOMETIME SATURDAY AFTERNOON ALL
THE WAY THROUGH MONDAY. THE COMBINATION OF STRONG WINDS AND
BUILDING SEAS WITH A LARGE NORTHWEST SWELL WILL VERY LIKELY
PRODUCE SMALL CRAFT ADVISORY CONDITIONS ACROSS THE REMAINDER OF
THE HAWAIIAN COASTAL WATERS FROM SATURDAY THROUGH MONDAY.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
HIGH SURF ADVISORY UNTIL 6 PM HST SUNDAY FOR NORTH AND WEST FACING
SHORES OF NIIHAU KAUAI OAHU AND MOLOKAI AND NORTH FACING SHORES OF
MAUI.
