500 AM HST SAT JAN 14 2006

.SYNOPSIS...
A HIGH NORTHEAST OF THE STATE IS PRODUCING TRADE WINDS OVER THE

APPROACHES FROM THE NORTHWEST. OUR WINDS WILL SHIFT TO SOUTHEAST AND
WEAKEN AND THE WEATHER WILL TURN MUGGY AND HAZY. THE FRONT WILL
WEAKEN TO A SHEARLINE...MOVE OVER KAUAI SUNDAY NIGHT AND STALL. A
HIGH MOVING EAST BEHIND THE SHEARLINE WILL BRING TRADES BACK ON
MARTIN LUTHER KING JUNIOR DAY. WINDS WILL SHIFT TO SOUTHEAST AGAIN

&&

.DISCUSSION...
REMNANTS OF AN OLD FRONTAL BAND ARE MOVING OVER THE ISLANDS IN THE
TRADE WIND FLOW. CLOUDS AND SHOWERS HAVE DECREASED SINCE LAST
EVENING AND WILL CONTINUE TO THIN OUT LATER TODAY.

A HIGH NORTHEAST OF THE ISLANDS IS MOVING AWAY TO THE EAST AND OUR
WINDS HAVE NOW STARTED TO WEAKEN AND VEER TO SLIGHTLY SOUTH OF EAST.
THE COMPUTER MODELS ALL SHOW THE HIGH MOVING FARTHER AWAY TO THE
EAST AND A FRONT MOVING TOWARDS THE MAIN HAWAIIAN ISLANDS FROM THE
NORTHWEST. EASTERLY TRADE WINDS WILL PERSIST NEAR THE BIG ISLAND
BUT WINDS OVER THE REST OF THE MAIN HAWAIIAN ISLANDS WILL SHIFT TO
SOUTHEAST AND WEAKEN. THE SOUTHEAST FLOW WILL CARRY VOG UP OVER THE
SMALLER ISLANDS AND THE LIGHT WINDS WILL PRODUCE MUGGY CONDITIONS.
THE ATMOSPHERE WILL REMAIN RATHER STABLE SO SHOWERS WILL BE LIMITED.

THE FRONT WILL WEAKEN TO A SHEARLINE AND MOVE OVER KAUAI EARLY
MONDAY NIGHT AND STALL. THE LATEST GFS RUNS SHOW CLOUDS AND SHOWERS
FROM THE SHEARLINE AFFECTING ONLY KAUAI. AS A NEW SURFACE HIGH
MOVES EASTWARD BEHIND THE SHEARLINE...TRADE WINDS WILL SPREAD BACK
OVER THE ISLANDS AND THE SHEARLINE WILL MOVE OFF TO THE WEST.

FROM TUESDAY ON...THE COMPUTER MODELS BECOME A BIT INCONSISTENT.
THE LATEST GFS RUNS SHOW A NEW FRONT MOVING TOWARDS THE MAIN
HAWAIIAN ISLANDS FROM THE NORTHWEST TUESDAY NIGHT. IT LOOKS LIKE
WINDS OVER THE ISLANDS WILL SHIFT TO SOUTHEAST BY WEDNESDAY AS THE
FRONT APPROACHES BUT THE GFS SHOWS THE FRONT STALLING NORTHWEST OF
THE ISLANDS AND WINDS SHIFTING BACK TO TRADES BY FRIDAY.

&&

.MARINE...
OUR EAST NORTHEAST SWELL REMAINED RATHER HIGH OVERNIGHT SO IT NOW
LOOKS AS IF SURF ALONG EAST-FACING SHORES MAY REMAIN ABOVE THE
ADVISORY LEVEL THROUGH THE DAY TODAY. WE HAVE EXTENDED THE HIGH
SURF ADVISORY TO REFLECT THIS. A NEW NORTHWEST SWELL WILL ARRIVE
TOMORROW NIGHT. SURF ALONG NORTH AND WEST-FACING SHORES WILL RISE
ABOVE THE ADVISORY LEVEL MONDAY AND MAY EVENTUALLY REACH THE WARNING
LEVEL.

&&

.UPDATE...
EAST SOUTHEAST WINDS HAVE STRENGTHENED OVER HALEAKALA SUMMIT SO WE
HAVE ISSUED A WIND ADVISORY...UPDATED THE WIND GRIDS AND UPDATED THE
TEXT FORECASTS.

.HFO WATCHES/WARNINGS/ADVISORIES...
