AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
1005 AM HST SAT DEC 29 2012

.SYNOPSIS...
LIGHT EAST TO SOUTHEAST FLOW WITH LOCAL LAND AND SEA BREEZES
DEVELOPING
IS EXPECTED THROUGH MONDAY. THIS WILL BRING AFTERNOON AND EVENING
CLOUD
BUILD UPS AND A POSSIBLE LIGHT SHOWER OR TWO FOR INTERIOR SECTIONS
OF THE ISLANDS...THEN CLEARING AT NIGHT. A WEAK FRONT WILL REACH
THE ISLANDS MONDAY...BRINGING AN INCREASE IN SHOWERS MONDAY NIGHT
THROUGH TUESDAY. NORTHEASTERLY WINDS WILL QUICKLY BUILD BEHIND THE
FRONT. MOISTURE UPSTREAM WILL FUEL A WET TRADE WIND PATTERN
THROUGH THE REST OF THE WEEK.

&&

.DISCUSSION...
A WEAK NORTHEAST TO SOUTHWEST ORIENTED RIDGE IS SLOWLY PUSHING
NORTHWARD WITH LATEST MODEL DATA SHOWING THE RIDGE AXIS OVER
KAUAI. THE PARENT HIGH PRESSURE REMAINS CENTERED FAR NORTHEAST OF
THE MAIN HAWAIIAN ISLANDS AND WILL CONTINUE TO MIGRATE EASTWARD
THROUGH THE WEEKEND. MEANWHILE...A NEARLY STATIONARY FRONTAL BOUNDARY
REMAINS SOME 200 MILES NORTHWEST OF KAUAI. THIS OVERALL SYNOPTIC
SETUP WILL KEEP PREVAILING LIGHT AND VARIABLE WINDS ACROSS THE
ISLANDS THROUGH MONDAY...WHICH WILL CONTINUE TO ALLOW FOR A LAND
AND SEA BREEZES PATTERN. EXPECT SOME AFTERNOON / EARLY
EVENING LOW CLOUDS AND A POSSIBLE LIGHT SHOWER OR TWO OVER
LEEWARD AND INTERIOR AREAS AS SEA BREEZES PUSH INLAND. LAND
BREEZES AT NIGHT WILL CLEAR OUT MOST OF THE CLOUD COVER OR
LINGERING SHOWERS THROUGH THE MORNING HOURS.

12Z HILO AND LIHUE SOUNDINGS AND MOISTURE ANALYSES DATA SHOW PWATS
AROUND 1-1.2 INCHES...JUST BELOW NORMAL. INVERSIONS LOOK A LITTLE
BETTER DEFINED IN BOTH SOUNDINGS...IN THE 5-7 KFT RANGE.
THEREFORE...MOISTURE WILL REMAIN LIMITED DURING THE REST OF THE
WEEKEND ALONG WITH A RELATIVELY STABLE ATMOSPHERE. SO ASIDE FROM A
FEW LIGHT AFTERNOON SHOWERS...NO SIGNIFICANT RAIN ACTIVITY IS
EXPECTED THROUGH MONDAY.

A DEVELOPING UPPER TROUGH AND JET STREAM CROSSING THE NORTH CENTRAL
PACIFIC WILL PUSH THE WEAK FRONT THAT IS CURRENTLY NORTHWEST OF
KAUAI ONTO THE ISLANDS MONDAY NIGHT AND TUESDAY. CONSENSUS AMONG
GLOBAL MODELS HAS IMPROVED AND NOW GFS IS TRENDING TOWARDS THE
PERSISTING ECMWF SOLUTION OF BRINGING THE WEAKENING FRONT ACROSS
THE SMALLER ISLANDS AND FINALLY BREAKING IT DOWN NEAR MAUI LATE
TUESDAY.

STRONG HIGH PRESSURE WILL OVERRUN THE BOUNDARY BRINGING A BRIEF
SURGE OF NORTHEASTERLY FRESH TO LOCALLY STRONG TRADES OVERNIGHT
MONDAY THROUGH TUESDAY MORNING. FOR NEW YEARS...EXPECT THE
INCREASE OF SHOWERS AND WINDS TO REACH KAUAI AT NIGHT NEW YEARS
EVE...WITH OAHU AND MAUI COUNTY WAITING UNTIL THE EARLY MORNING
HOURS ON THE 1ST FOR IT TO REACH. THIS IS BASED ON THE CURRENT MODEL
RUNS AND SUBJECT TO CHANGE IN THE NEXT COUPLE OF DAYS.

THE TRADES WILL ALLOW MUCH OF THE FRONTAL MOISTURE TO FOCUS ON
WINDWARD AND MAUKA AREAS. THESE WINDS ARE EXPECTED TO CONTINUE
FROM TUESDAY THROUGH THURSDAY. ABUNDANT MOISTURE WILL REMAIN
UPSTREAM AS THE FRONT FALLS APART. AS THE TRADES CONTINUE THROUGH
THE REST OF THE WEEK...THIS MOISTURE WILL GET FUNNELED TOWARDS THE
SMALLER MAIN HAWAIIAN ISLANDS PUTTING US INTO A WET TRADE WIND
PATTERN THROUGH THE END OF THE WEEK. SHOWERS WILL FOCUS ON THE
TYPICAL WINDWARD AND MAUKA AREAS...WITH SHOWERS CARRYING OVER THE
LEEWARD SIDES FROM TIME TO TIME DUE TO THE ELEVATED TRADE WINDS.
FOR RIGHT NOW IT LOOKS LIKE THE BIG ISLAND MAY BE A BIT DRIER THAN
THE OTHER ISLANDS NEXT WEEK BECAUSE THE FETCH WILL BE CONCENTRATED
FURTHER TO THE NORTH.

&&

.AVIATION...
THE LIGHT EAST SOUTHEAST TO SOUTHEAST LOW-LEVEL FLOW ACROSS THE
STATE MAY PRODUCE SOME LOW CEILINGS...MAINLY MVFR...DUE TO LOW CLD
AND -SHRA ALONG THE SOUTHEAST FACING SLOPES OF THE BIG ISLAND
THROUGH TONIGHT. ELSEWHERE...LOCAL AFTERNOON SEA BREEZES MAY PRODUCE
CLOUD BUILD UPS OVER INTERIOR AND MOUNTAINOUS SECTIONS OF SOME OF
THE SMALLER ISLANDS DURING THE AFTERNOON HOURS THROUGH SUNDAY. THESE
CLOUDS SHOULD DISSIPATE DURING THE EARLY EVENING HOURS AS NIGHT TIME
LAND BREEZES DEVELOP. OTHERWISE...EXPECT VFR CONDITIONS TO PREVAIL
ACROSS THE ALOHA STATE.

&&

.MARINE...
A LARGE NORTHWEST SWELL WILL BEGIN ARRIVING AROUND NOON TODAY
BEGINNING WITH KAUAI THEN SPREADING EASTWARD DOWN THE ISLAND
CHAIN THROUGH TONIGHT. AS OF 900 AM HST...THE HIGHER PERIOD ENERGY
FROM THIS SWELL WAS FELT AT BUOY 51101 WHICH IS ABOUT 5-6 HOURS
AWAY FROM KAUAI. A HIGH SURF WARNING HAS BEEN ISSUED FOR NORTH AND
WEST SHORES OF NIIHAU KAUAI OAHU AND MOLOKAI...AND NORTH FACING
SHORES OF MAUI BEGINNING AT NOON TODAY. EXTRA LARGE SURF IS
EXPECTED ALONG EXPOSED NORTH AND WEST SHORES AS THIS SWELL PEAKS
ON SUNDAY. PLEASE SEE CFWHFO FOR MORE INFORMATION.

COMBINED SEAS WILL ALSO GROW ABOVE THE SMALL CRAFT ADVISORY /SCA/
THRESHOLD TONIGHT. WATERS EXPOSED TO THE LARGE NW SWELL WILL LIKELY
REACH SCA THRESHOLD...AROUND 10 FT STARTING TONIGHT. THESE
CONDITIONS ARE EXPECTED TO CONTINUE INTO MONDAY.

A MUCH SMALLER RE/ENFORCING NORTHWEST SWELL WILL ARRIVE THURSDAY.
ELSEWHERE A SERIES OF SMALL SOUTH SWELLS WILL MAINTAIN BACKGROUND
SURF ALONG SOUTH FACING SHORES.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
HIGH SURF WARNING FROM NOON TODAY TO 6 PM HST MONDAY FOR NORTH
AND WEST FACING SHORES OF NIIHAU KAUAI OAHU MOLOKAI AND NORTH FACING
