AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
1000 AM HST TUE FEB 15 2011

.SYNOPSIS...
A FRONT TO THE WEST OF THE ISLANDS WILL CONTINUE TO DISRUPT TRADE
WIND FLOW THROUGH THE WEEK. SOUTHERLY WINDS WILL CONTINUE TO BRING
HAZY CONDITIONS TO MANY AREAS WITH SHOWERS MOSTLY FOUND OVER
THE INTERIOR OF THE ISLANDS DURING THE AFTERNOON AND EVENINGS. HIGH
CLOUDS AHEAD OF THE FRONT WILL LIMIT SUNSHINE AT TIMES. THE FRONT
WILL APPROACH KAUAI ON THURSDAY...BRINGING AN INCREASE IN SHOWER
ACTIVITY TO KAUAI AND POSSIBLY OAHU LATER THIS WEEK AND ON INTO THE
WEEKEND.

&&

.DISCUSSION...
AN AREA OF LOW PRESSURE SEEN SPINNING ABOUT 1200 MILES TO THE WEST
NORTHWEST OF KAUAI IS THE PRIMARY WEATHER FEATURE AFFECTING THE
ALOHA STATE. THE PROXIMITY OF THE LOW PLACES THE ISLANDS IN LIGHT
SOUTHEASTERLY FLOW. THE WINDS ARE LIGHT ENOUGH FOR LOCAL LAND AND
SEA BREEZE CIRCULATIONS OCCURING OVER A GOOD PORTION OF THE STATE.
THE LIGHT SOUTHEAST FLOW IS DRAWING UP VOLCANIC HAZE WHICH IS
EXPECTED TO LINGER FOR THE NEXT SEVERAL DAYS. A BROAD SWATH OF
LAYRED CLOUDS WITH EMBEDDED DEEP CONVECTION LIES OVER THE OPEN
WATERS WEST OF THE STATE. RADAR SHOWS SHOWERS TO THE SOUTH AND WEST
OF KAUAI BUT THERE TRAJECTORY IS KEEPING THEM OFF OF THE ISLANDS
THEMSELVES. A FEW SHOWERS ARE ALSO SEEN MOVING INTO THE SOUTHEAST
KAU COAST. DAYTIME HEATING MAY CAUSE SOME CLOUD BUILDUPS OVER
INTERIOR AREAS TODAY AND WEDNESDAY WITH ISOLATED SHOWERS A
POSSIBILITY DURING THE AFTERNOON AND EVENING HOURS.

MODELS ARE IN GOOD AGREEMENT WITH THE LOW EVENTUALLY MOVING OFF
TOWARD THE NORTH NORTHEAST AND ITS ASSOCIATED FRONTAL BOUNDARY
GRADUALLY SHIFTING EASTWARD. THE BIG QUESTION IS HOW FAR EAST THE
FRONT EVENTUALLY MOVES TO. THE FRONTAL BAND IS FORECAST TO APPROACH
KAUAI ON THURSDAY AND THEN STALL VERY NEAR KAUAI ON FRIDAY AND THEN
LINGER THERE THROUGH THE WEEKEND. RAIN CHANCES WILL BE HIGHEST OVER
KAUAI AND GRADUALLY LOWER EASTWARD DOWN THE ISLAND CHAIN.

THE FRONTAL BOUNDARY IS THEN EXPECTED TO LINGER NEAR OR JUST NORTH
OF KAUAI INTO EARLY NEXT WEEK SO TRADE WINDS WILL REMAIN ABSENT FROM
THE FORECAST. RAIN CHANCES WILL CONTINUE TO BE HIGHER NEAR KAUAI AND
LESS OVER THE EASTERN ISLANDS.

&&

.MARINE...
THE PRESSURE GRADIENT BETWEEN BUOYS 51000 AND 51002 HAS BEEN
INCREASING OVER THE PAST SEVERAL HOURS. WIND REPORTS FROM SOUTH
POINT INDICATE SMALL CRAFT ADVISORY CONDITIONS ARE LIKELY OCCURING
OVER THE WATERS SOUTH OF THE BIG ISLAND. THUS A SMALL CRAFT ADVISORY
HAS BEEN POSTED FOR THOSE WATERS AS WELL AS THE WINDWARD WATERS
NORTH OF MAUI COUNTY AND THE BIG ISLAND.

A NEW NORTH SWELL IS EXPECTED TO FILL IN WEDNESDAY NIGHT AND LINGER
INTO FRIDAY. THIS SWELL WILL LIKELY RESULT IN ADVISORY LEVEL SURF
ALONG EAST FACING SHORES...BUT WILL REMAIN BELOW ADVISORY LEVELS
ALONG NORTH FACING SHORES.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
WIND ADVISORY UNTIL 6 PM HST THIS EVENING FOR BIG ISLAND NORTH
AND EAST-BIG ISLAND INTERIOR.

SMALL CRAFT ADVISORY UNTIL 6 PM HST WEDNESDAY FOR OAHU WINDWARD
WATERS-KAIWI CHANNEL-MAUI COUNTY WINDWARD WATERS-ALENUIHAHA
