AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST SUN FEB 8 2015

.SYNOPSIS...
SOUTHERLY WINDS WILL GRADUALLY STRENGTHEN THROUGH EARLY MONDAY
MORNING...ESPECIALLY ON KAUAI AND OAHU AS A VIGOROUS COLD FRONT
APPROACHES FROM THE NORTHWEST. STRONG AND GUSTY SOUTHWEST WINDS WILL
CONTINUE TO RAMP UP ACROSS AREAS TO THE NORTH AND EAST OF THE HIGHER
TERRAIN ON THE SMALLER ISLANDS STARTING ON MONDAY AS THE FRONT
NEARS. A BATCH OF MOISTURE AHEAD OF THE FRONT WILL BRING SHOWERS TO
PORTIONS OF THE BIG ISLAND ON MONDAY...WHILE RAINFALL ALONG THE
FRONT WILL BE FOCUSED ON KAUAI BY MONDAY AFTERNOON...BEFORE THE WET
WEATHER MOVES DOWN THE REST OF THE ISLAND CHAIN FROM MONDAY NIGHT
THROUGH TUESDAY.

&&

.DISCUSSION...
SYNOPTIC ANALYSIS OF THE SURFACE FEATURES IN THE VICINITY OF THE
MAIN HAWAIIAN ISLANDS INDICATES AN EAST NORTHEAST TO WEST SOUTHWEST
ORIENTED SURFACE RIDGE IS LOCATED JUST SOUTHEAST OF THE BIG ISLAND
EARLY THIS EVENING. THIS RIDGE IS WEAKENING AS IT SHIFTS SLOWLY
TOWARD THE EAST SOUTHEAST. ELSEWHERE...THE LEADING EDGE OF A BAND OF
LAYERED CLOUDS AND SHOWERS ASSOCIATED WITH A VIGOROUS COLD FRONT
APPROACHING THE ISLANDS IS ABOUT 325 MILES NORTHWEST OF LIHUE EARLY
THIS EVENING. THE LEADING EDGE OF THIS BAND OF CLOUDS AND RAINFALL
IS MOVING TOWARD THE EAST SOUTHEAST AT ABOUT 20 MPH.

LOW-LEVEL WINDS ARE GRADUALLY STRENGTHENING AND SHIFTING OUT OF THE
SOUTHWEST TONIGHT AS THE COLD FRONT CONTINUES TO ADVANCE TOWARD THE
ISLANDS. SHOWERS DEVELOPING IN PREFRONTAL CONVERGENCE BANDS ARE
EXPECTED TO BE SPOTTY ACROSS THE ISLANDS THIS EVENING. HOWEVER...
SHOWERS HAVE ALREADY DEVELOPED NEAR KAUAI...WHICH REQUIRED AN EARLY
EVENING FORECAST UPDATE. WE ARE ALSO MONITORING AN AREA OF TROPICAL
MOISTURE CURRENTLY ABOUT 35 MILES SOUTHEAST OF THE BIG ISLAND THAT
WILL DRIFT NORTHWARD OVERNIGHT. THE BULK OF THE SHOWERS WITHIN THIS
AREA OF MOISTURE ARE EXPECTED TO BE HELD OFFSHORE BY LAND BREEZES
THROUGH TONIGHT.

THE FORECAST MODELS APPEAR TO BE IN RELATIVELY GOOD AGREEMENT IN
REGARDS TO THE TIMING OF THE FRONT AND THE BULK OF ITS ASSOCIATED
MOISTURE REACHING KAUAI MONDAY AFTERNOON...OAHU MONDAY NIGHT...THEN
MAUI COUNTY ON TUESDAY. ELSEWHERE...THE ABOVE MENTIONED BATCH OF
MOISTURE WILL LIKELY SPREAD OVER THE BIG ISLAND ON MONDAY.

ALTHOUGH THERE COULD BE LOCALLY HEAVY DOWNPOURS ALONG THE FRONT...
THE MAIN CONCERN IS FOR STRONG AND GUSTY DOWNSLOPE WINDS TO THE
NORTH AND EAST OF THE HIGHER TERRAIN ON THE SMALLER ISLANDS...SUCH
AS THE WAIANAE AND KOOLAU MOUNTAIN RANGES ON OAHU...AHEAD OF THE
FEATURE. AS NOTED IN THE PREVIOUS DISCUSSION...THE GFS AND ECMWF
MODELS CONTINUE TO DEPICT A LOW LEVEL DRY SLOT DEVELOPING LATER
TONIGHT FROM OAHU TO MAUI WITH 850 MB WINDS INCREASING TO 40 KT ON
MONDAY. AT THE SAME TIME...THE LOW-LEVEL INVERSION IS EXPECTED TO
PERSIST WITHIN THE DRY SLOT JUST AHEAD OF THE FRONT. GIVEN RECENT
MODEL CONSISTENCY...CHANCES ARE HIGH THAT STRONG SOUTHWESTERLY WIND
GUSTS WILL INCREASE TO THE WIND ADVISORY CRITERIA OVER AREAS TO THE
NORTHEAST OF THE HIGHER TERRAIN ON THE SMALLER ISLANDS. AS A
RESULT...A WIND ADVISORY HAS BEEN ISSUED FOR PORTIONS OF KAUAI...
OAHU...MOLOKAI...MAUI...AND LANAI ON MONDAY. WINDS WILL DECREASE AND
SHIFT OUT OF THE WEST TO NORTHWEST WITH CONDITIONS DRYING
CONSIDERABLY AFTER THE FRONT PASSES.

ACROSS THE HIGHEST ELEVATIONS ON THE BIG ISLAND AND MAUI...THE
LARGE-SCALE PATTERN MAINTAINING THE RECENT EXTENDED RUN OF
WESTERLIES WILL MAINTAIN STRONG WINDS ACROSS THE SUMMITS OF MAUNA
KEA AND MAUNA LOA THROUGH MUCH OF THIS WEEK. IN ADDITION...THE
STRONG WINDS MAY ALSO AFFECT THE SUMMIT OF MOUNT HALEAKALA AT TIMES.
WESTERLY WINDS HAVE BEEN HOLDING JUST ABOVE THE HIGH WIND WARNING
THRESHOLD AT AROUND 60 MPH ON THE BIG ISLAND SUMMIT. THESE SUMMIT
WINDS ARE EXPECTED TO GRADUALLY RAMP UP OVERNIGHT...PEAK ON
TUESDAY...AND LIKELY REMAIN WITHIN THE WARNING CRITERIA MOST OF THIS
WEEK. THE SUMMIT OF MOUNT HALEAKALA MAY ALSO EXPERIENCE WINDS
REACHING THE WIND ADVISORY CRITERIA HEAD OF THE INCOMING FRONT
STARTING LATE MONDAY.

DURING THE MEDIUM AND EXTENDED RANGE FORECAST PERIODS...THE MAIN
HAWAIIAN ISLANDS WILL REMAIN LOCKED IN THE UNUSUALLY LONG STRETCH OF
GUSTY WESTERLY LOW-LEVEL WINDS. THE WEST TO NORTHWEST FLOW WILL
PRODUCE DRY CONDITION ON WEDNESDAY AFTER THE FRONT CLEARS THE STATE.
ANOTHER SURFACE HIGH WILL LIKELY PASS BY AROUND THURSDAY...LEADING
TO A DECREASE IN WINDS. ANOTHER FRONT IS EXPECTED TO AFFECT THE
STATE FROM LATE FRIDAY INTO NEXT WEEKEND. DUE TO DIFFERENCES IN THE
OUTPUT FROM THE LONG-RANGE FORECAST MODELS...THERE IS STILL A GREAT
DEAL OF UNCERTAINTY REGARDING THE DETAILS OF THE TIMING AND THE
WEATHER ASSOCIATED WITH THE NEXT FRONT.

&&

.AVIATION...
COULD SEE SOME BRIEF MVFR CIGS AND SOME PRE-FRONTAL -SHRA...BUT
PREDOMINANTLY VFR CONDITIONS ARE EXPECTED THROUGH 10/06Z. THE ONE
EXCEPTION IS ACROSS KAUAI...WHERE SHRA ASSOCIATED WITH A COLD FRONT
MAY REDUCE CIGS/VSBYS TO MVFR LEVELS AROUND 10/03Z.

SOUTH TO SOUTHWEST SURFACE WINDS WILL BE ON THE INCREASE AT THE
TERMINALS AHEAD OF THE COLD FRONT AS WELL...WITH WINDY CONDITIONS
EXPECTED AT MANY OF THE TAF SITES.

AIRMET TANGO IS IN EFFECT FOR LOW LEVEL TURB NORTH THROUGH EAST OF
THE ISLANDS...AND THIS AIRMET IS EXPECTED TO CONTINUE THROUGH THE
DAY ON MONDAY.

&&

.MARINE...
A BROAD AND SLOW MOVING GALE LOW OVER THE NORTH CENTRAL PACIFIC
OCEAN WILL PRODUCE A NEW ELEVATED AND LONG-LASTING NORTHWEST
SWELL...WHICH WILL LIKELY IMPACT NORTH AND WEST FACING SHORES OF THE
ISLANDS DURING MOST OF THE NEW WORK WEEK. THIS SWELL WILL ARRIVE
MONDAY...WITH SURF HEIGHTS RAPIDLY BUILDING TO THE HIGH SURF WARNING
CRITERIA ALONG MOST NORTH AND WEST FACING SHORES OF THE SMALLER
ISLANDS MONDAY NIGHT. GUIDANCE FROM THE WAVEWATCH III MODEL
INDICATES THIS NORTHWEST SWELL WILL LIKELY PEAK ON TUESDAY...AND
REMAIN WITHIN WARNING CRITERIA THROUGH WEDNESDAY. BY TUESDAY...THE
LARGE SWELL WILL IMPACT THE KONA COAST OF THE BIG ISLAND WHERE A
HIGH SURF WARNING MAY ALSO BE REQUIRED.

AS THE SOUTHWEST WINDS INCREASE OVERNIGHT...SMALL CRAFT ADVISORY
/SCA/ CRITERIA WINDS ARE POSSIBLE AROUND KAUAI LATE TONIGHT AS A
VIGOROUS FRONT APPROACHES. SCA WINDS WILL SPREAD ACROSS THE REST OF
THE STATE ON MONDAY AND WILL LIKELY PERSIST ACROSS SOME WATERS AND
CHANNELS INTO TUESDAY. IN ADDITION...ELEVATED COMBINED SEAS OF 10
FEET OR MORE BUILDING ON MONDAY WILL LIKELY PERSIST THROUGH AT LEAST
THURSDAY. A SCA HAS BEEN ISSUED THROUGH TUESDAY AFTERNOON FOR BOTH
WINDS AND SEAS...BUT IT WILL LIKELY NEED TO BE EXTENDED BEYOND THAT
TIME DUE TO PERSISTENT HIGH SEAS.
