AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
1000 AM HST SAT AUG 31 2013

.SYNOPSIS...
TRADE WINDS WILL GRADUALLY STRENGTHEN OVER THE NEXT COUPLE OF DAYS
AS HIGH PRESSURE BUILD IN TO THE NORTH OF THE STATE. CLOUDS AND
PASSING SHOWERS WILL FAVOR WINDWARD AND MAUKA AREAS WITH A FEW BRIEF
PASSING SHOWERS POSSIBLE OF A FEW LEEWARD LOCATIONS. THE HIGH WILL
WEAKEN AND MOVE TO A POSITION FAR NORTHEAST OF THE STATE AROUND THE
MIDDLE OF NEXT WEEK WITH TRADE WINDS EXPECTED TO DROP OFF AT THAT
TIME.

&&

.DISCUSSION...
HIGH PRESSURE WILL BUILD BACK IN NORTH OF THE STATE OVER THE NEXT
FEW DAYS. THIS WILL ALLOW TRADE WINDS TO PICK UP TO MODERATE LEVELS.
TOWARD THE MIDDLE OF NEXT WEEK THE HIGH WILL MOVE EASTWARD TO A
POSITION FAR NORTHEAST OF THE STATE WHILE AN AREA OF LOW PRESSURE
DEVELOPS FAR NORTHWEST OF THE STATE. THIS WILL CAUSE THE HIGHS
ASSOCIATED RIDGE AXIS TO BE NUDGED SOUTHWARD CLOSER TO THE STATE
RESULTING IN LIGHTER TRADES. LOCAL LAND AND SEA BREEZES MAY DEVELOP
AT THAT TIME IN THE LIGHTER WIND REGIME.

THE ATMOSPHERE IS SLIGHTLY UNSTABLE IN THE VICINITY OF MAIN HAWAIIAN
ISLANDS AS EVIDENT BY THE WEAK LOW LEVEL INVERSIONS IN THE 12Z
SOUNDINGS. THIS IS DUE TO AN UPPER LEVEL TROUGH CENTERED JUST TO
THE NORTHWEST OF KAUAI. MOISTURE EMBEDDED IN THE TRADES IS PRODUCING
SOME PASSING SHOWERS OVER WINDWARD AND MAUKA AREAS. THE UPPER TROUGH
IS FORECAST TO DRIFT EASTWARD OVER THE NEXT COUPLE OF DAYS AS AN
UPPER RIDGE BUILD IN FROM THE NORTHEAST. THIS SHOULD ALLOW FOR THE
LOW LEVEL INVERSION TO STRENGTHEN. A DRIER AIRMASS UPWIND OF THE
ISLANDS AT THAT TIME WILL KEEP THE AREA RATHER DRY WITH JUST BRIEF
LIGHT PASSING SHOWERS OVER SOME WINDWARD AND MAUKA AREAS. UNDER THE
LIGHTER WIND REGIME EXPECTED TOWARD THE MIDDLE AND LATTER HALF OF
NEXT WEEK...CLOUDS MAY BUILD UP OVER SOME LEEWARD AND INTERIOR AREAS
DURING THE AFTERNOON HOURS RESULTING IN SOME SHOWERS OVER THOSE
AREAS.

&&

.AVIATION...
THE RECENTLY STRENGTHENED TRADES WILL SWEEP MORE CLOUDS AND SHOWERS
INTO THE ISLANDS OVER THE WEEKEND. THUS EXPECT SOME OCCASIONAL MVFR
CEILINGS AND VISIBILITIES MAINLY ALONG THE WINDWARD SECTIONS.
TRADEWIND STRENGTH WILL BE MONITORED FOR THE POSSIBILITY OF
MECHANICAL LOW-LEVEL TURBULENCE FORMING LEE OF THE MOUNTAINS. BUT
WINDS CURRENTLY REMAIN MARGINAL AT MEETING AIRMET CRITERIA AT THIS
TIME.

&&

.MARINE...
THE STRENGTHENING TRADE WINDS WILL CAUSE SMALL CRAFT ADVISORY
CONDITIONS OVER THE TYPICALLY WINDY WATERS AROUND MAUI COUNTY AND
THE
BIG ISLAND THROUGH MONDAY.

THE STRONGER TRADES WILL ALSO CAUSE A BIT OF AN INCREASE IN SHORT
PERIOD CHOPPY SURF ALONG EAST FACING SHORES. THERE WILL BE A SERIES
OF SMALL...MAINLY BACKGROUND SOUTH SWELLS THROUGHOUT THE FORECAST
PERIOD. THERE MAY ALSO BE A COUPLE OF SMALL PULSES FROM THE NORTH
NEXT WEEK.

&&

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