AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
1032 AM HST SUN JAN 15 2012

.SYNOPSIS...
A STALLED FRONT NORTHWEST OF KAUAI WILL REMAIN NEARLY STATIONARY
THE NEXT COUPLE OF DAYS...WITH SOUTHERLY WINDS PREVAILING THROUGH
WEDNESDAY. THE SOUTH WINDS WILL BRING WARMER CONDITIONS...INCREASED
MOISTURE...AND A BETTER CHANCE FOR SHOWERS...ESPECIALLY ALONG SOUTH
FACING SLOPES AND COASTS OF KAUAI AND OAHU. HIGH CLOUDS WILL COME
AND GO OVER THE NEXT SEVERAL DAYS...PERIODICALLY MAKING FOR CLOUDY
CONDITIONS. A RETURN TO A MOSTLY DRY AND SUNNY TRADE WIND WEATHER
IS EXPECTED BY FRIDAY.

&&

.DISCUSSION...
A COLD FRONT NW OF KAUAI HAS STALLED 400 MILES NW OF THE GARDEN
ISLE. THIS FRONT IS NEVER EXPECTED TO REACH THE STATE...BUT WILL
REMAIN IN PLACE NW OF KAUAI THROUGH MID-WEEK. THE STALLED FRONT
HAS TURNED WINDS OVER THE ISLANDS OUT OF THE SOUTH. THE SOUTHERLY
FLOW WILL CONTINUE THROUGH WEDNESDAY BRINGING MOIST...TROPICAL
AIR OVER THE STATE. BOTH THE GFS AND EUROPEAN MODELS DEPICT
CONVERGENT BANDS OF RAINFALL MOVING FROM SOUTH TO NORTH OVER THE
ISLANDS DURING THIS TIME. THE LOCATION AND TIMING OF THESE SHOWER
BANDS ARE HIGHLY DIFFICULT TO FORECAST.

AS OF THIS MORNING...LOW-LEVEL CONVERGENCE IS FORMING SHOWERS OVER
THE KAUAI CHANNEL WITH SOME RAINFALL SKIRTING THE WAIANAE COAST.
SCATTERED SHOWERS HAVE BEEN MOVING OVER THE SMALLER ISLANDS
THROUGHOUT THE MORNING...WHILE THE KAU AND PUNA DISTRICTS OF THE
BIG ISLAND HAVE SEEN STEADY RAIN THIS MORNING.

THE INCREASED MOISTURE AND KONA WINDS WILL BRING WETTER THAN NORMAL
WEATHER THROUGH WEDNESDAY WITH A FOCUS OVER KAUAI AND OAHU. SOUTH
FACING SLOPES WILL SEE MORE RAIN THAN NORMAL DURING THIS PERIOD AS
THE KONA WINDS FORCE MOISTURE UP THE SOUTHERN FACING SLOPES.
LOCALLY HEAVY SHOWERS ARE POSSIBLE MONDAY NIGHT AND TUESDAY OVER
KAUAI AND OAHU AS THE FRONT DRAWS UP TROPICAL MOISTURE IN THE
SOUTHERLY FLOW.

HIGH CLOUDS ARE EXPECTED TO PERIODICALLY SPREAD OVER THE ISLANDS
FROM THE WNW THROUGH MIDWEEK...MAKING FOR CLOUDY CONDITIONS AS
THEY DO SO.

SOUTHERLY FLOW TYPICALLY BRINGS THE THREAT OF HAZE AND REDUCED
AIR QUALITY TO THE ISLANDS...AS VOLCANIC EMISSIONS EMANATING FROM
SE BIG ISLAND SPREAD OVER THE BIG ISLAND...AND THE SMALLER
ISLANDS. CURRENT FORECAST INCLUDES HAZE OVER THE BIG ISLAND AND
MAUI COUNTY THROUGH THURSDAY.

THE SECOND HALF OF THE WEEK LOOKS TO TRANSITION BACK TO TRADE
WINDS AS A SURFACE RIDGE SHUNTS THE STALLED COLD FRONT TO THE
NORTH AND ALLOWS WINDS FROM THE EAST BACK IN TO THE ISLANDS.

&&

.AVIATION...
AN AIRMET REMAINS UP FOR LOW LEVEL TURBULENCE OVER AND NORTHWEST
THROUGH NORTHEAST OF MOUNTAINS FROM KAUAI TO MAUI COUNTY DUE TO
SOUTHERLY WIND FLOW. VFR CONDITIONS PREVAIL AT ALL TAF SITES.

&&

.MARINE...
WITH DIMINISHING NW SWELL AND COMBINED SEAS BELOW THE SMALL CRAFT
ADVISORY /SCA/ CRITERION OF 10 FEET...NO MARINE WARNINGS OR
ADVISORIES ARE CURRENTLY POSTED. S/SW WINDS WILL BE FRESH NEAR KAUAI
AND OAHU THROUGH MONDAY NIGHT...BUT ARE EXPECTED TO REMAIN BELOW SCA
CRITERION OF 25 KT THROUGH THE FORECAST PERIOD. HOWEVER...WITH S
WINDS OVER KAUAI WATERS NEAR 20 KT AT THEIR PEAK TODAY THROUGH
MONDAY NIGHT...COMBINED SEAS ARE LIKELY TO EXCEED 10 FEET MONDAY
INTO TUESDAY.

SOME OF THE CONTRIBUTION TO THE COMBINED SEAS WILL BE A MODERATE NW
SWELL THAT WILL BUILD ON MONDAY...AND PEAK MONDAY NIGHT AND TUESDAY.
RESULTANT SURF HEIGHTS WILL APPROACH ADVISORY LEVELS ALONG EXPOSED N
AND W SHORES...BUT INITIAL ESTIMATES ARE THAT SURF WILL REMAIN
BELOW ADVISORY LEVELS.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
NONE.
