Area forecast discussion, Aug 27, 8:30 PM HST, 33 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST MON AUG 27 2012

.SYNOPSIS...
A SURFACE HIGH PRESSURE REMAINS FAR NORTH OF THE MAIN HAWAIIAN
ISLANDS...PROVIDING TRADE WINDS ACROSS THE STATE THROUGH THE WEEK.
PASSING SHOWERS WILL FAVOR WINDWARD AND MAUKA AREAS.

&&

.DISCUSSION...
TRADE WIND WEATHER CONTINUES OVER THE STATE THIS EVENING AS A
SURFACE HIGH PRESSURE PERSISTS FAR NORTH OF THE ISLANDS. ONLY MINOR
CHANGES ARE EXPECTED WITH REGARDS TO THIS HIGH IN THE NEXT FEW
DAYS. AN UPPER LEVEL TROUGH IS DEEPENING WEST OF THE ISLANDS...AND
IS BRINGING SOME HIGH CLOUDS TO THE WESTERN PORTION OF THE STATE.
LOOKS LIKE THESE HIGH CLOUDS ARE THICK ENOUGH TO OBSCURE THE
SKIES...THUS HAVE UPDATED THE FORECAST TO HAVE MORE CLOUDINESS FOR
THE WESTERN ISLANDS THIS EVENING. THESE HIGH CLOUDS MAY LINGER
ACROSS THE STATE FOR IN THE NEXT FEW DAYS AS WELL. LOW LEVEL
MOISTURE HAS BEEN DEEP ENOUGH TO PROVIDE SOME WETTING RAIN TO THE
ISLANDS. LATEST FORECAST CHARTS INDICATE THIS MOISTURE WILL REMAIN
NEAR THE ISLANDS FOR THE NEXT FEW DAYS...ALLOWING SOME ENHANCED
SHOWERS TO AFFECT THE STATE.

IN ALL...TRADE WIND WEATHER WILL REIGN THROUGH THE WEEK...WITH
PASSING CLOUDS AND SHOWERS AFFECTING MAINLY WINDWARD AND MOUNTAIN
AREAS...WHILE KONA AREA OF THE BIG ISLAND WILL SEE AFTERNOON AND
EVENING CLOUDS AND SHOWERS. SOME SHOWERS MAY REACH THE LEE SIDE OF
THE SMALLER ISLANDS UNDER THE MODERATE WINDS.

A DRIER AIR MASS MAY RETURN TO THE ISLANDS OVER THE WEEKEND AS
INDICATED BY THE MODELS. THE STATE MAY SEE DRIER TRADE WIND WEATHER
BY THEN.

&&

.AVIATION...
VFR CONDITIONS SHOULD PREVAIL FOR MOST TERMINALS OVERNIGHT.
WINDWARD AREAS WILL EXPERIENCE BRIEF MVFR CONDITIONS AND MOUNTAIN
OBSCURATIONS DUE TO PASSING CLOUDS AND SHOWERS.

&&

.MARINE...
THE WINDS HAVE INCREASED ENOUGH IN THE PAST FEW HOURS TO WARRANT THE
ISSUANCE OF A SMALL CRAFT ADVISORY FOR THE USUAL WINDIER COASTAL
WATERS AROUND MAUI AND THE BIG ISLAND. BELIEVE THE WINDS WILL REMAIN
STRONG ENOUGH FOR THE ADVISORY TO STAY UP THROUGH EARLY WEDNESDAY AT
THIS POINT.

A SMALL SOUTHEASTERLY SWELL WILL CONTINUE THROUGH MUCH OF THE
WEEK...BUT THE BIG ISLAND WILL BLOCK MUCH OF THIS SWELL AND
PREVENT IT FROM REACHING THE SMALLER ISLANDS. A SMALL SOUTH SWELL
MAY REACH THE ISLANDS ON WEDNESDAY.

&&

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