AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST WED MAR 7 2012

.SYNOPSIS...
NORTHEAST TRADE WINDS WILL BUILD TONIGHT BECOMING FRESH TO LOCALLY
STRONG ON THURSDAY. SHOWERS WILL FOCUS ON WINDWARD AND MOUNTAIN
AREAS...BUT THE STRENGTHENING WINDS WILL BRING SHOWERS TO SOME
LEEWARD AREAS OVER THE NEXT COUPLE DAYS. MORE UNSETTLED WEATHER...
INCLUDING THE CHANCE FOR THUNDERSTORMS...IS POSSIBLE FRIDAY AND
FRIDAY NIGHT AS AN UPPER LOW PASSES NEAR THE STATE. MORE TYPICAL
TRADE WIND WEATHER IS EXPECTED BY MONDAY.

&&

.DISCUSSION...
NOT EXPECTING TO MAKE ANY SIGNIFICANT CHANGE TO THE FORECAST THIS
EVENING. HOWEVER MAY NEED TO MAKE SOME TWEAKS OVERNIGHT FOR THE
DEVELOPING WEATHER SITUATION ON THURSDAY NIGHT THROUGH FRIDAY NIGHT.

IN THE SHORT TERM...HIGH PRESSURE TO THE FAR NORTHWEST IS BRINGING
TRADES BACK TO THE ISLANDS. THE 1041 MB...AT 2PM...ANALYZED HIGH
PRESSURE SYSTEM IS PRODUCING A FAIRLY STRONG GRADIENT OVER THE
ISLANDS...RESULTING IN THE TRADE WINDS PICKING UP. MODELS ARE IN
GOOD AGREEMENT WITH THE HIGH SINKING SOUTHWARD OVER THE NEXT 24
HOURS...WHICH WILL RESULT IN WINDS CONTINUING TO PICK UP...DESPITE
THE SMALL DECREASE IN THE HIGH/S STRENGTH.

THE BIG WEATHER QUESTION COMES WITH THE PATTERN FOR THURSDAY NIGHT
THROUGH FRIDAY NIGHT/EARLY SATURDAY. AN UPPER LEVEL LOW IS EXPECTED
TO FORM ALONG THE UPPER LEVEL TROUGH NORTHWEST OF THE ISLANDS. THE
MODELS ARE IN GOOD AGREEMENT WITH THAT SITUATION...BUT DO DIFFER ON
THE PLACEMENT AND STRENGTH. THERE IS ALSO GOOD AGREEMENT WITH THE
MODELS WITH THE DEVELOPMENT OF A SURFACE TROUGH FORMING OVER THE
ISLANDS AS A RESULT OF THE UPPER LEVEL SYSTEM. HOWEVER THE MODELS
DIFFER IN THE STRENGTH OF THIS SURFACE FEATURE.

THE PRESENCE OF THE UPPER LEVEL SYSTEM AND SURFACE TROUGH WILL
CERTAINLY BRING SOME UNSTABLE AIR TO THE ISLANDS...BUT EXACTLY HOW
MUCH AND WHERE ARE THE BIG QUESTIONS. THE MAIN QUESTION IS HOW MUCH
OF THE TRADE WINDS WILL REMAIN IN PLACE. IF THE SURFACE WINDS DO
BECOMING MORE SOUTHEASTERLY...WE/LL SEE MORE DEVELOPMENT.

ALTHOUGH THE FORECAST INCLUDES THE CHANCE FOR HEAVY RAIN AND
THUNDERSTORMS...THIS EVENT IS A BIT DIFFERENT THAN THE EVENT OVER
THIS PAST WEEKEND AND AT THE BEGINNING OF THIS WEEK. THE MAIN
DIFFERENCE IS THAT THIS UPCOMING EVENT SHOULD BE SHORTER IN
DURATION. ALL THE MODELS AGREE WITH MOVING THE UPPER LOW TO THE WEST
OF THE ISLANDS BY SATURDAY NIGHT...WHICH WILL HELP THE ATMOSPHERE TO
START TO STABILIZE. THAT BEING SAID...AREAS THAT DID RECEIVE A LOT
OF RAIN DURING THE LAST EVENT WILL LIKELY GET MORE RAIN WITH THIS
EVENT.

WILL BE MONITORING WINDS CLOSELY...PARTICULARLY OVER THE NEXT 24
HOURS OR SO...SINCE SOME AREAS MAY BE APPROACHING WIND ADVISORY
CRITERIA WITH THE HIGH SINKING SOUTHWARD.

AS THE UPPER LEVEL FEATURE MOVES WEST AND FADES OUT...EXPECT MORE
TYPICAL TRADE WIND WEATHER FOR THE START OF THE NEW WORK WEEK.

&&

.AVIATION...
AN AIRMET FOR LOW LEVEL TURBULENCE FOR KAUAI...OAHU AND MOLOKAI AS
STURDY LOW LEVEL NORTH-NORTHEAST WINDS FILL IN ACROSS THE NORTHWEST
PART OF THE ISLAND CHAIN. EXPECT THIS AIRMET TO BE EXPANDED TO MORE
ISLANDS AS THE WINDS FILL IN.

&&

.MARINE...
NORTH-NORTHEAST SWELL CONTINUES TO DECLINE...THE HIGH SURF ADVISORY
CONTINUES FOR THE EAST FACING SHORES. WITH THE WINDS ON THE
INCREASE...AN ADVISORY FOR WIND SWELL MAY BE NEEDED. WILL BE
MONITORING THE SITUATION OVERNIGHT.

SMALL CRAFT ADVISORIES POSTED FOR ALL HAWAIIAN WATERS FOR 25 KNOT
WINDS OR GREATER OR COMBINED SEAS WHICH RUNS THROUGH SATURDAY
MORNING.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
HIGH SURF ADVISORY UNTIL 6 AM HST THURSDAY FOR EAST FACING SHORES
OF KAUAI OAHU MOLOKAI MAUI AND BIG ISLAND.

SMALL CRAFT ADVISORY UNTIL 6 AM HST SATURDAY FOR ALL HAWAIIAN
WATERS.
