AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
950 AM HST TUE SEP 15 2015

.SYNOPSIS...
MODERATE TO STRONG TRADE WINDS WILL PREVAIL THROUGH NEXT WEEKEND...
BRINGING PERIODS OF CLOUDS AND SHOWERS TO THE ISLANDS. ALTHOUGH
CLOUDS AND SHOWERS WILL FAVOR WINDWARD AREAS...THE WINDS WILL BE
STRONG ENOUGH TO PUSH THEM TO LEEWARD AREAS AT TIMES. A PARTICULARLY
SHOWERY BAND CURRENTLY PASSING OVER THE SMALLER ISLANDS WILL
GRADUALLY CLEAR THROUGH THE AFTERNOON. MEANWHILE...ANOTHER AREA OF
SHOWERS EAST OF THE ISLANDS IS EXPECTED TO ARRIVE OVER WINDWARD BIG
ISLAND OVERNIGHT AND WEDNESDAY. ANOTHER INCREASE IN SHOWERS IS
POSSIBLE THIS WEEKEND AS AN UPPER LEVEL DISTURBANCE MOVES TOWARD THE
ISLANDS FROM THE NORTHEAST.

&&

.DISCUSSION...
SURFACE HIGH PRESSURE CENTERED FAR NORTH OF THE ISLANDS WILL BUILD
SOUTH...AND THEN SOUTHEAST...THROUGH THE WEEKEND. THIS WILL BE THE
PRIMARY FEATURE DRIVING WHAT IS EXPECTED TO BE A MODERATE TO LOCALLY
STRONG LOW-LEVEL TRADE WIND FLOW OVER THE ISLANDS. TRADE WINDS WILL
INITIALLY FAVOR AN ENE DIRECTION...THEN EVENTUALLY TURN TO THE E AND
ESE THROUGH THE WEEKEND AS THE HIGH MOVES TO A POSITION NE OF THE
ISLANDS...AND LOW PRESSURE POTENTIALLY DEEPENS TO THE W OF THE AREA.

A COUPLE OF SHOWERY LOW CLOUD BANDS ARE AFFECTING THE SHORT TERM
FORECAST...WITH ONE PARTICULARLY SHOWERY BAND CURRENTLY MOVING
THROUGH THE SMALLER ISLANDS. 24 HOUR RAINFALL TOTALS AT WETTEST
WINDWARD LOCATIONS RANGE FROM 5 TO 8 INCHES DUE TO THE PASSAGE OF
THIS BAND...WHICH STARTED MOVING OVER THE ISLANDS OVERNIGHT. WHILE
RAINFALL RATES HAVE NOT BEEN VERY HIGH AND ARE NOT EXPECTED TO
INCREASE...THE PERSISTENT LIGHT TO MODERATE RAIN HAS LED TO AN
INCREASE IN WATER LEVELS IN STREAMS. THIS BAND IS EXPECTED TO PUSH W
OF THE SMALLER ISLANDS THROUGH THIS AFTERNOON...BUT MAY CONTINUE TO
DAMPEN KAUAI INTO TONIGHT. WHILE WINDWARD AREAS WILL ABSORB MOST OF
THE RAINFALL...SOME OF THE SHOWERS WILL CONTINUE TO SPREAD OVER
LEEWARD SECTIONS.

ALTHOUGH A DRYING TREND IS EXPECTED OVER THE SMALLER ISLANDS
OVERNIGHT AND WEDNESDAY...AN E-W ORIENTED SHOWERY LOW CLOUD BAND
CURRENTLY ABOUT 50 TO 300 MILES E OF WINDWARD BIG ISLAND IS EXPECTED
TO ARRIVE OVERNIGHT THROUGH WEDNESDAY. THESE SHOWERS WILL FOCUS OVER
WINDWARD AREAS OF THE BIG ISLAND...POTENTIALLY SPREADING TO WINDWARD
MAUI. ASSOCIATED FORECAST GRIDS WILL BE MODIFIED TO BE BETTER IN
LINE WITH THIS FORECAST PHILOSOPHY. TRADE WIND WEATHER WILL
OTHERWISE PERSIST INTO THE WEEKEND...BRINGING PASSING CLOUDS AND
SHOWERS TO WINDWARD AREAS...WITH NO ORGANIZED SHOWER AREAS EXPECTED.

WINDS MAY TURN TOWARD THE ESE LATE THIS WEEKEND AS THE HIGH
RELOCATES TO A POSITION NE OF THE ISLANDS...AND A LOW POTENTIALLY
DEVELOPS W OF THE AREA. AT THE SAME TIME...A CLOSED LOW ALOFT WILL
MOVE TOWARD THE ISLANDS FROM THE NE. WHILE THE BULK OF THE
INSTABILITY ASSOCIATED WITH THE LOW IS EXPECTED TO REMAIN OFFSHORE
TO THE NE OF THE ISLANDS...THE CLOSE PROXIMITY OF THE LOW WILL
LIKELY LEAD TO AN INCREASE IN TRADE WIND SHOWERS...SOME OF WHICH MAY
BECOME HEAVY.

&&

.AVIATION...
HIGH PRESSURE FAR NORTH OF THE STATE WILL KEEP MODERATE TO LOCALLY
BREEZY TRADE WINDS IN PLACE OVER THE ISLANDS FOR THE NEXT FEW
PERIODS. THE PHTO 12Z SOUNDING SHOWS A WEAK INVERSION BETWEEN
6-7 KFT AND THE VAD WIND PROFILES FROM SOK AND HMO RADARS SHOW WINDS
BELOW 9 KFT BETWEEN 15-25 KT. THEREFORE...WE WILL KEEP AIRMET TANGO
FOR LOW LEVEL TURB SOUTH THROUGH WEST OF THE MOUNTAINS IN PLACE.

TRADE WINDS WILL CONTINUE TO CARRY LOW CLOUDS AND SHOWERS
ACROSS THE WINDWARD AREAS. AIRMET SIERRA IS POSTED FOR NORTH THROUGH
EAST SLOPES ON THE SMALLER ISLANDS. THIS WILL BE TAILORED TO ADD OR
SUBTRACT AREAS AS NEEDED THROUGHOUT THE DAY.

&&

.MARINE...
A SMALL CRAFT ADVISORY /SCA/ IS IN EFFECT FOR ALL HAWAIIAN WATERS...
EXCEPT THE WINDWARD BIG ISLAND WATERS...DUE TO STRONG TRADE WINDS.
WHILE THE SCA CURRENTLY EXPIRES FOR MOST AREAS THIS AFTERNOON...IT
HAS BEEN EXTENDED THROUGH WEDNESDAY FOR THE WINDIER ZONES AROUND
MAUI AND THE BIG ISLAND. THESE ZONES MAY REQUIRE A FURTHER EXTENSION
IN TIME AS WINDS WILL BE CLOSE TO CRITERIA.

A SMALL TO MODERATE SSW SWELL IS EXPECTED TO CONTINUE THROUGH
THURSDAY...MAINTAINING MODERATE SURF ALONG S FACING SHORES. A
SLIGHTLY LARGER SSW SWELL ON FRIDAY IS EXPECTED TO CAUSE SURF ALONG
S FACING SHORES TO APPROACH THE HIGH SURF ADVISORY THRESHOLD BEFORE
DIMINISHING OVER THE WEEKEND. TRADE WINDS WILL GENERATE MODERATE BUT
CHOPPY SURF ALONG E FACING SHORES OVER THE NEXT SEVERAL DAYS.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
SMALL CRAFT ADVISORY UNTIL 6 PM HST WEDNESDAY FOR MAALAEA BAY-PAILOLO
CHANNEL-ALENUIHAHA CHANNEL-BIG ISLAND LEEWARD WATERS-BIG ISLAND
