AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
800 PM HST SUN SEP 14 2014

.SYNOPSIS...
HOT AND HUMID CONDITIONS WILL CONTINUE THROUGH MUCH OF THE WEEK.
LIGHT WINDS WILL PERSIST THROUGH WEDNESDAY...ALLOWING FOR AFTERNOON
SEA BREEZES AND MUGGY CONDITIONS. SPOTTY SHOWERS ARE EXPECTED
TONIGHT OVER THE SMALLER ISLANDS AS AN OLD FRONTAL BOUNDARY PASSES
THROUGH. OTHERWISE... CLOUDS AND SHOWERS WILL FORM IN THE
AFTERNOONS WITH OVERNIGHT LAND BREEZES CLEARING SKIES. LIGHT TRADE
WINDS WITH LEEWARD SEA BREEZES ARE EXPECTED FOR THE SECOND HALF
OF THE WEEK.

&&

.DISCUSSION...
LOW PRESSURE NORTHWEST OF THE STATE HAS CUT OFF TRADE WINDS...
LEAVING THE ISLANDS UNDER A STABLE CONVECTIVE REGIME. SEA BREEZES
AND SPOTTY AFTERNOON SHOWERS WILL FORM IN THE AFTERNOONS... WITH
GENTLE DOWNSLOPE FLOW PARTIALLY CLEARING SKIES AT NIGHT. LIGHT
NORTHERLY FLOW NEAR THE SURFACE IS SLOWLY PUSHING AN OLD FRONTAL
BOUNDARY ASSOCIATED WITH THE AFOREMENTIONED LOW OVER THE SMALLER
ISLANDS TONIGHT.

A RAGGED THIN LINE OF SHOWERS ASSOCIATED WITH THE FRONTAL
BOUNDARY IS NOW LOCATED ACROSS THE NORTHERN TIP OF OAHU AND
STRETCHES EAST... JUST NORTH OF MOLOKAI. SKIES REMAIN CLOUDY OVER
OAHU WITH SOME SPOTTY SHOWERS FALLING OVERNIGHT. SOME OF THESE
SHOWERS WILL REACH THE NORTHERN SLOPES OF MOLOKAI AND MAUI LATER
TONIGHT. OVER THE GARDEN ISLE...PARTLY CLOUDY SKIES WILL PREVAIL
TONIGHT WITH A FEW POP-UP SHOWERS FORMING ALONG THE TAIL END OF
THE FRONTAL BOUNDARY. THE BIG ISLAND LOOKS TO BE DRY THROUGH THE
NIGHT WITH CLEARING SKIES. BY MONDAY AFTERNOON...MOST AREAS WILL HAVE
AT LEAST PARTLY CLOUDY SKIES AS SEA BREEZES KICK IN AND DAYTIME
HEATING IS AT ITS MAXIMUM. SPOTTY SHOWERS ARE EXPECTED WITH SOME
BRIEF DOWNPOURS POSSIBLE.

DEW POINTS AROUND THE STATE HAVE INCREASED A NOTCH OVER THE PAST
12 HOURS AND ARE NOW HOVERING IN THE LOW 70/S... MAKING WEATHER
CONDITIONS FEEL STICKY AND UNCOMFORTABLE. SIMILAR CONDITIONS ARE
EXPECTED THROUGH THE WEEK. AS THE OLD FRONTAL BOUNDARY PUSHES
THROUGH THE ISLANDS TONIGHT AND MONDAY... DEW POINTS WILL INCREASE
A BIT FURTHER. COMBINE THESE HIGHER DEW POINTS WITH HIGH
TEMPERATURES NEAR 90 DEGREES F... AND AFTERNOON CONDITIONS WILL GO
FROM STICKY AND UNCOMFORTABLE INTO THE OPPRESSIVE RANGE ON MONDAY.
SLIGHTLY LOWER DEW POINTS ARE EXPECTED FOR THE REST OF THE WEEK...
BUT THE HOT AND HUMID CONDITIONS WILL REMAIN.

A WEAK HIGH PRESSURE TO THE NORTHWEST WILL BRING LIGHT TRADE
WINDS BACK TO THE ISLANDS WEDNESDAY AND FOR THE SECOND HALF OF THE
WEEK. HOWEVER... MUGGY CONDITIONS WILL CONTINUE. THE TRADES WILL FOCUS
SHOWERS OVER THE WINDWARD SLOPES BUT AFTERNOON LEEWARD SEA BREEZES
WILL BRING SPOTTY CLOUDS AND LIMITED SHOWERS TO LEEWARD AND
INTERIOR AREAS.

&&

.AVIATION...
CONVECTIVE LOW CLOUDINESS FROM DAYTIME HEATING WILL DISSIPATE AS
THE EVENING PROGRESSES...LEADING TO CLEARING OVER THE EASTERN END OF
THE ISLAND CHAIN.

HOWEVER...A  DIFFUSE BAND OF MOISTURE JUST NORTH OF THE STATE MAY
PRODUCE BRIEF MVFR CIGS AND VIS IN SHRA AS IT MOVES OVER NORTH
FACING TERRAIN OF KAUAI...OAHU...AND MOLOKAI OVERNIGHT.

&&

.MARINE...
WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY
LEVELS THROUGH THE FORECAST PERIOD.

THE CURRENT LONG PERIOD SOUTH SWELL IS PRODUCING ADVISORY LEVEL SURF
ALONG SOUTH FACING SHORES. THE ADVISORY HAS BEEN EXTENDED THROUGH
MONDAY NIGHT. THE SOUTH SWELL WILL SLOWLY SUBSIDE MONDAY THROUGH
WEDNESDAY. SMALL SOUTHERLY SWELLS ARE EXPECTED THURSDAY THROUGH
SATURDAY TIME PERIOD.

THE CURRENT SMALL NORTHWEST SWELL WILL GRADUALLY LOWER ON TUESDAY.
OTHER SMALL NORTH NORTHWEST SWELLS CAN BE EXPECTED DURING THE
REST OF THE WEEK.

THE AFTERNOONS WITH OVERNIGHT LAND BREEZES CLEARING SKIES. LIGHT
TRADE WINDS ARE EXPECTED FOR THE SECOND HALF OF THE WEEK.

&&

.DISCUSSION...
NO SIGNIFICANT CHANGES TO THE FORECAST PHILOSOPHY THIS AFTERNOON.
THERE HAVE BEEN SOME CHANGES TO THE POPS/SKY/WX/QPF GRIDS THROUGH
MONDAY NIGHT.

THE WESTERN END OF THE EAST TO WEST ORIENTED BAND ASSOCIATED WITH A
SURFACE TROUGH IS ABOUT 45 MILES NORTH OF HONOLULU THIS AFTERNOON.
THE BAND HAS STARTED TO BREAK UP OVER THE LAST FEW HOURS...BUT WE
ARE STILL EXPECTING THE CLOUDS TO HAVE SOME IMPACT ON THE ISLANDS
OVERNIGHT.

WITH THE LIGHT WINDS ALLOWING DAYTIME SEA BREEZES AND HEATING...WE
ANTICIPATE CLOUDS AND SHOWERS DURING THE AFTERNOON. THE BAND OF
CLOUDS SINKING SOUTHWARD WILL HELP TO BRING SOME CLOUDS AND SHOWERS
TO THE SMALLER ISLANDS OVERNIGHT. OTHERWISE...EXPECT LAND BREEZES AT
NIGHT TO CLEAR THE ISLANDS.

THE LIGHT WINDS...COMBINED WITH DEWPOINTS IN THE LOW 70S TOMORROW
WILL MAKE IT FEEL STICKY AND UNCOMFORTABLE. SLIGHTLY LOWER DEW
POINTS ARE EXPECTED TUESDAY AND WEDNESDAY...BUT THE HOT AND HUMID
CONDITIONS WILL REMAIN.

A WEAK HIGH PRESSURE TO THE NORTHWEST WILL MOVE NORTH OF THE ISLANDS
DURING THE SECOND HALF OF THE WEEK WHICH WILL BRING LIGHT TRADE
WINDS. HOWEVER...MUGGY CONDITIONS WILL CONTINUE. THE TRADES WILL
FOCUS SHOWERS OVER THE WINDWARD SLOPES BUT WINDS WILL BE LIGHT

SOUTHWESTERN SLOPES OF HALEAKALA AS WELL AS OVER PORTIONS OF THE
WEST MAUI MOUNTAINS. OVER THE BIG ISLAND LOW CLOUDS ARE BANKED UP
OVER MOST OF THE KONA AND KAU SLOPES WITH SCATTERED LOW CLOUDS SEEN
OVER THE HILO AND PUNA DISTRICTS.

JUST SCATTERED PATCHES OF LOW CLOUDS ARE SEEN OVER THE OPEN WATERS
TO THE SOUTH OF THE STATE AND OVER THE WATERS SURROUNDING PORTIONS
OF THE BIG ISLAND COASTAL WATERS.

A COUPLE AREAS OF THUNDERSTORMS ARE SEEN ALONG THE ITCZ FAR TO THE
SOUTHEAST OF THE STATE WITH ANOTHER AREA OF THUNDERSTORMS SEEN FAR

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
1000 AM HST SUN SEP 14 2014

.SYNOPSIS...
HOT AND HUMID CONDITIONS WILL CONTINUE INTO NEXT WEEK. LIGHT WINDS
WILL PERSIST THROUGH WEDNESDAY...ALLOWING FOR AFTERNOON SEA BREEZES
AND MUGGY CONDITIONS. CLOUDS AND SHOWERS WILL FORM IN THE AFTERNOONS
WITH OVERNIGHT LAND BREEZES CLEARING SKIES. LIGHT TRADE WINDS ARE
EXPECTED FOR THE SECOND HALF OF THE WEEK.

&&

.DISCUSSION...
LIGHT WINDS OVERNIGHT CLEARED OUT THE CLOUDS OVER ALL THE ISLANDS
AND SURROUNDING COASTAL WATERS. JUST BEFORE 9 AM...SOME CLOUDS WERE
FORMING OVER THE ISLANDS. THE WESTERN END OF A ROUGHLY EAST TO WEST
ORIENTED LINE OF CLOUDS IS ABOUT 70 MILES NORTH OF OAHU THIS
MORNING. THESE CLOUDS ARE ASSOCIATED WITH A SURFACE TROUGH THAT IS
SINKING SOUTH TOWARDS THE ISLANDS. OVERNIGHT...A CONVERGENCE BAND
AHEAD OF THE TROUGH MOVED SOUTHWEST AND MOVED OVER THE KAUAI
NORTHWEST WATERS.

WITH THE LIGHT WINDS ALLOWING DAYTIME SEA BREEZES AND HEATING...WE
ALREADY ANTICIPATE MORE CLOUDS AND SHOWERS DURING THE AFTERNOON. THE
BAND OF CLOUDS SINKING SOUTHWARD WILL HELP TO ENHANCE THESE CLOUDS
AND SHOWERS THIS AFTERNOON AND EVENING. WHILE THE LIGHT WINDS WILL
ALLOW FOR LAND BREEZES OVERNIGHT WHICH SHOULD CLEAR THE ISLANDS OF
CLOUDS...THE LEFTOVER MOISTURE FROM THE TROUGH MAY KEEP A FEW CLOUDS
AND SHOWERS AROUND OVERNIGHT.

OVERNIGHT DEWPOINTS DROPPED INTO THE MID 60S...AND ARE EXPECTING
DEWPOINTS TO RISE TO AROUND 70 DEGREES TODAY. WITH LIGHT WINDS AND
DEWPOINTS EXCEEDS 70...IT WILL FEEL STICKY AND UNCOMFORTABLE. HIGHER
DEWPOINTS ARE EXPECTED TO MOVE OVER THE ISLANDS ON MONDAY...WHICH
WILL MAKE IT EVEN MORE UNCOMFORTABLE. SLIGHTLY LOWER DEW POINTS ARE
EXPECTED TUESDAY AND WEDNESDAY... BUT THE HOT AND HUMID CONDITIONS
WILL REMAIN.

A WEAK HIGH PRESSURE TO THE NORTHWEST WILL MOVE NORTH OF THE ISLANDS
DURING THE SECOND HALF OF THE WEEK WHICH WILL BRING LIGHT TRADE
WINDS. HOWEVER...MUGGY CONDITIONS WILL CONTINUE. THE TRADES WILL
FOCUS SHOWERS OVER THE WINDWARD SLOPES BUT WINDS WILL BE LIGHT
ENOUGH FOR SOME AFTERNOON LEEWARD SEA BREEZES THAT WILL WILL BRING
SPOTTY CLOUDS AND LIMITED SHOWERS TO LEEWARD AND INTERIOR AREAS.

&&

.AVIATION...
DAYTIME SEA BREEZES WILL OVERPOWER A RELATIVELY WEAK NORTH TO
NORTHEAST BACKGROUND FLOW TODAY...LEADING TO AFTERNOON CLOUDS WITH
ISOL MVFR CIGS AND VIS IN SHRA OVER INTERIOR AND MOUNTAIN AREAS. A
WEAK BAND OF MOISTURE WILL DRIFT SOUTHWARD NEAR KAUAI TODAY...
GIVING HIGHER CHANCES FOR MVFR CONDITIONS ON KAUAI. EXPECT CLEARING
WITH LAND BREEZES TONIGHT...THOUGH SOME MOISTURE COULD LINGER NEAR
NORTHERN ISLANDS.

&&

.MARINE...
WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY
LEVELS THROUGH THE FORECAST PERIOD.

THE CURRENT LONG PERIOD SOUTH SWELL IS PRODUCING ADVISORY LEVEL SURF
ALONG SOUTH FACING SHORES. THE ADVISORY CURRENTLY GOES THROUGH
TONIGHT...BUT DEPENDING ON THE TRENDS TODAY...WE MAY NEED TO EXTEND
THE ADVISORY INTO MONDAY. THE SOUTH SWELL WILL SLOWLY DIMINISH
MONDAY THROUGH WEDNESDAY...WITH ONLY SMALL...SUMMERTIME BACKGROUND
SURF EXPECTED FOR THE REMAINDER OF THE WEEK.

A NORTHWEST SWELL IS BRING A BUMP TO THE NORTH FACING SHORES TODAY.
THAT SWELL IS EXPECTED TO PEAK LATE TODAY AND MONDAY. ANOTHER PULSE
FROM THE NORTH- NORTHWEST IS EXPECTED TUESDAY AND WEDNESDAY...
FOLLOWED BY A DECLINE ON THURSDAY AND FRIDAY.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
HIGH SURF ADVISORY UNTIL 6 AM HST MONDAY FOR SOUTH FACING SHORES
ALL ISLANDS.

HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
1230 UTC SUN SEP 14 2014

BASED ON DATA THROUGH 1200 UTC SEPTEMBER 14 2014

WEAK RIDGING PERSISTS AT THE SURFACE OVER THE MAIN HAWAIIAN ISLANDS
RESULTING IN WEAK WIND FLOW AND SLOW CLOUD MOTIONS OF 5 TO 10 MPH TO
THE SOUTHWEST. THE WEAK FLOW HAS ALLOWED LAND BREEZES TO SET IN OVER
THE STATE. THE HAS ALLOWED SKIES TO CLEAR OUT OVER MOST OF THE
STATE...THOUGH LINGERING MOISTURE AROUND THE BIG ISLAND IS KEEPING
CLOUDS AND A FEW SHOWERS PRESENT ACROSS BOTH WINDWARD AND LEEWARD
SIDES.

TRADE WIND FLOW OVER THE STATE IS BEING SUPPRESSED BY A WEAKENING
COLD FRONT ABOUT 50 MILES NORTH OF KAUAI...MOVING SOUTH AT AROUND 5
MPH. THE FRONT IS MARKED BY A 225 MILE-WIDE BAND OF BROKEN CUMULUS
CLOUDS CENTERED ALONG AN AXIS FROM 30N142W...24N151W...AND 25N161W.
ISOLATED TOWERING CUMULUS CLOUDS ARE PRESENT WITHIN THE CLOUD BAND
WITH TOPS REACHING UP TO 32000 FEET.

WATER VAPOR SHOWS A NEARLY STATIONARY WEAK UPPER LEVEL TROUGH WITH
AN AXIS FROM 27N142W TO 21N160W. THE UPPER LEVEL TROUGH IS HELPING
TO TRIGGER ISOLATED THUNDERSTORMS NEAR A SURFACE TROUGH ALONG
19N180W TO 10N171W ALMOST 1200 MILES SOUTHWEST OF KAUAI. THE SURFACE
TROUGH IS TRAVELLING TO THE WEST NEAR 15 MPH AND HAS A WEAK LOW
EMBEDDED NEAR 11N177W. ISOLATED THUNDERSTORMS RISE AS HIGH AS 52000
FT WITHIN WITHIN 400 MILES EAST OF THE TROUGH.

A SURFACE TROUGH IS LOCATED ALONG THE ITCZ...LOCATED ABOUT 1300
SOUTHWEST OF HONOLULU. THIS TROUGH AXIS GOES FROM 15N176W TO
10N176W...MOVING WEST AT 10 MPH. THE TROUGH IS PRODUCING SCATTERED
THUNDERSTORMS WITH WITH TOPS TO 54000 BETWEEN 09N TO 15N AND 172W TO
178E.

ANOTHER AREA OF THUNDERSTORMS PERSISTS ALONG THE ITCZ ASSOCIATED
WITH A WEAK SURFACE TROUGH. THE STORMS COVER AN AREA FROM 09N TO 12N
AND 140W TO 150W WITH TOPS TO 51000 FEET.

AS EXPECTED...THE SMALLER ISLANDS BEGAN THE DAY CLEAR...AND BY 9
AM...WE ARE STARTING TO SEE SOME CLOUDS FORMING OVER THE ISLANDS.
THE BIG ISLAND HAD SOME CLOUDS OVERHEAD OVERNIGHT...PARTICULARLY
OVER THE NORTH HILO...SOUTH HILO...AND PUNA DISTRICTS. SOME
ADDITIONAL CLOUDS ARE CONTINUING TO MOVE INTO THESE AREAS OVER THE
NEXT FEW HOURS. ADDITIONAL CLOUDS ARE STARTING TO FORM OVER OTHER
PORTIONS OF THE ISLANDS.

A SURFACE LOW ABOUT 940 MILES NORTHEAST OF OAHU HAS A SURFACE FRONT
IDENTIFIED BY A NEARLY EAST TO WEST ORIENTED CLOUD BAND ABOUT 210
MILES NORTH OF OAHU AT 9 AM. ANOTHER FRONTAL SYSTEM MORE THAN 950
NORTHWEST OF THE ISLANDS IS HELPING TO PUSH A SURFACE RIDGE OVER THE
ISLANDS...WEAKENING OUR WINDS.

THE LIGHTER WINDS WILL ALLOW FOR AFTERNOON SEA BREEZES THAT WILL
RESULT IN A BUILD UP OF CLOUDS AND SHOWERS OVER THE ISLANDS...THAT
SHOULD CLEAR OUT AT NIGHT WITH LAND BREEZES. THIS PATTERN IS
EXPECTED TO REPEAT ITSELF FOR THE NEXT COUPLE OF DAYS. WHILE NEITHER
FRONTAL SYSTEM MENTIONED ABOVE ARE EXPECTED TO REACH THE
ISLANDS...SOME LEFTOVER MOISTURE FROM THEM WILL LIKELY ENHANCE SOME
SHOWERS BEGINNING AS EARLY AS TONIGHT. THE ATMOSPHERE OVER THE
ISLANDS REMAINS STABLE THROUGHOUT...SO WHILE THE INCREASE IN
MOISTURE WILL LIKELY INCREASE THE NUMBER OF SHOWERS AROUND THE
ISLANDS...RAINFALL TOTALS ARE NOT EXPECTED TO BE SIGNIFICANT.

A NEW HIGH WILL BUILD SLOWLY EASTWARD FROM THE DATELINE DURING OF
THE SECOND HALF OF THE WEEK WILL ALLOW LIGHT TO MODERATE TRADE WINDS
TO GRADUALLY RETURN.

&&

.AVIATION...
LIGHT TRADE WINDS WILL FOCUS CLOUDS AND A FEW SHOWERS ACROSS
WINDWARD SECTIONS WITH SOME LOCAL MVFR CONDITIONS OVER THE SLOPES.
CLOUDS AND WIDELY SCATTERED SHOWERS WILL DEVELOP OVER SOME LEEWARD
AND INTERIOR AREAS THIS AFTERNOON...WITH ISOLATED MVFR CONDITIONS
POSSIBLE. OTHERWISE...VFR CONDITIONS WILL PREVAIL ACROSS THE AREA
THROUGH TONIGHT.

&&

.MARINE...
WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY
LEVELS THROUGH THE FORECAST PERIOD.

THE VERY LONG PERIOD SOUTH SWELL IS SLOW TO BUILD AT THE
BUOYS...WITH BUOY 51004 SHOWING THE MOST SIGNIFICANT HEIGHTS. SURF
ALONG THE SOUTH FACING SHORES IS STILL EXPECTED TO RISE TODAY...AND
REMAIN ELEVATED THROUGH SUNDAY NIGHT...BEFORE SLOWLY DIMINISHING
NEXT WEEK.

ELSEWHERE...A SHORT-LIVED MODERATE NORTHWEST SWELL IS EXPECTED TO
ARRIVE LATE IN THE DAY SUNDAY...AND GRADUALLY DIMINISH THROUGH THE
FIRST HALF OF NEXT WEEK.

.DISCUSSION...
CURRENT SATELLITE AND RADAR SHOWS CLOUDS AND SHOWERS HAVE INCREASED
OVER THE BIG ISLAND...AND WINDWARD MAUI AND MOLOKAI THIS MORNING
DUE TO AN INFLUX OF MOISTURE COMING IN FROM UPSTREAM. SOUNDINGS
FROM THIS MORNING SHOWS AN ELEVATED INVERSION OF 12000 FEET AT
HILO AND A RELATIVELY MOIST PRECIPITABLE WATER VALUE OF 1.55
INCHES. EXPECTING THIS MOISTURE TO REMAIN OVER THE BIG ISLAND
TODAY AND TONIGHT BEFORE TRANSVERSING WESTWARD. ISOLATED SHOWERS
ARE ALSO IMPACTING THE WINDWARD SIDE OF OAHU.

A SURFACE RIDGE IS PRESENT OVER THE ISLANDS RESULTING VERY LIGHT
PRESSURE GRADIENT AND WINDS. THE LIGHT WIND FLOW REGIME WILL
RESULT IN WARM CONDITIONS TODAY. SEA BREEZES FROM HEATING OF THE
LAND WILL PRODUCE CLOUDS AND SHOWERS OVER THE INTERIOR OF THE
ISLANDS FROM LATE MORNING TO EARLY EVENING. THE BIG ISLAND WILL
SEE THE GREATEST AREAL COVERAGE OF SHOWERS EXTENDING UP TO THE
HIGHER ELEVATIONS TODAY. LAND BREEZES WILL BREAK UP THE CLOUDS AND
SHOWERS TONIGHT. THIS DIURNAL WEATHER PATTERN WILL CONTINUE
THROUGH AT LEAST THE FIRST HALF OF NEXT WEEK.

THE MODELS BRING VARYING AMOUNT OF PRECIPITABLE WATER INTO THE
ISLANDS STARTING SUNDAY THROUGH MOST OF NEXT WEEK...THOUGH THE
TREND IS THAT IT WILL INCREASE. THE ATMOSPHERE IS EXPECTED TO
REMAIN STABLE...SO THE ADDITIONAL LOW LEVEL MOISTURE WILL LIKELY
MEAN AN INCREASE IN THE NUMBER OF SHOWERS FOR ALL ISLANDS...WITH MOST
SHOWER ACTIVITY OCCURRING DURING THE AFTERNOON AND EARLY EVENING
HOURS. IT IS POSSIBLE WE MAY SEE ISOLATED MODERATE OR HEAVIER
SHOWERS AT TIMES...BUT OVERALL ATMOSPHERIC DYNAMICS DOES NOT
SUPPORT ANY ELEVATED CHANCE FOR THIS.

A LARGE DEEP LAYERED ANTICYCLONE WILL BUILD SLOWLY EASTWARD FROM THE
DATE LINE TO THE NORTH OF THE STATE...ALLOWING LIGHT TO MODERATE
TRADE WINDS TO GRADUALLY RETURN DURING LATE NEXT WEEK.


&&

.AVIATION...
LIGHT TRADE WINDS WILL FOCUS CLOUDS AND SHOWERS ACROSS WINDWARD
SECTIONS THIS MORNING. A SMALL LOW LEVEL CIRCULATION MOVING WSW PAST
THE WINDWARD BIG ISLAND WILL BRING SCATTERED SHOWERS ALONG WITH
PERIODS OF MVFR CONDITIONS TO THE LOWER PUNA AND KAU COASTS THIS
MORNING...AND AN AIRMET FOR MOUNTAIN OBSCURATION MAY BE NEEDED.
CLOUDS AND WIDELY SCATTERED SHOWERS WILL DEVELOP ALONG SEABREEZES
