HAWAIIAN ISLANDS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
400 AM HST THU FEB 17 2005

.SYNOPSIS...
DRY TRADE WIND WEATHER WILL CONTINUE THROUGH THE WEEKEND...THANKS TO
A HIGH PRESSURE RIDGE NORTH OF THE ISLANDS. SHOWERS WILL BE FEW AND
LIGHT...AND MOSTLY OVER WINDWARD AND MAUKA AREAS.

&&

.DISCUSSION...
THE SUBTROPICAL RIDGE TO THE NORTH BETWEEN 25N AND 30N WILL PUT
MODERATE TO FRESH TRADE WINDS OVER HAWAII THROUGH THE WEEKEND AT
LEAST. HOWEVER...A SURFACE TROUGH MOVING EASTWARD ACROSS THE NORTH
PACIFIC WILL LIKELY ERODE THE RIDGE TO ITS SOUTH...RESULTING IN A
SLIGHT DECREASE IN WINDS STARTING SUNDAY AND CONTINUING INTO NEXT
WEEK.

SUBSIDENCE ASSOCIATED WITH AN UPPER LEVEL RIDGE DIRECTLY OVER THE
STATE WILL CAP THE MARINE LAYER AT A RELATIVELY LOW 5 TO 6 THOUSAND
FEET. TRADE SHOWERS WILL BE LIMITED TO FEW OR NONE STATEWIDE. LOW
LEVEL MOISTURE TRAPPED BENEATH THE INVERSION...IN THE FORM OF VERY
STABLE STRATOCUMULUS CLOUDS...WILL INCREASE IN COVERAGE AT NIGHT AND
DECREASE IN COVERAGE DURING THE DAY...ESPECIALLY OVER WINDWARD
WATERS. THIS WILL ALSO MAKE FOR SOMEWHAT CLOUDY SKIES WINDWARD AT
NIGHT...AND HAVE ATTEMPTED TO ACCOUNT FOR THIS IN SKY GRIDS. HAVE
ALSO DECREASED POPS INTO THIS WEEKEND IN GRIDS AS NO SIGNIFICANT
CHANGE FROM CURRENT REGIME IS EXPECTED.

AN UPPER LEVEL TROUGH APPROACHING FROM THE NORTHWEST MAY CAUSE AN
INCREASE IN SHOWERS AROUND THE MIDDLE OF NEXT WEEK. WILL BE ABLE TO
SAY MORE ON THIS FEATURE AND ITS EFFECTS POSSIBLY BY THIS WEEKEND.

&&

.MARINE...
NORTHWEST SWELL HAS INCREASED OVERNIGHT AT BUOY 51001...AND WILL
RESULT IN ADVISORY LEVEL SURF ALONG VARIOUS NORTH AND WEST FACING
SHORES THROUGH TONIGHT. A NORTHEAST SWELL HAS ALSO BEEN DETECTED AT
THE UNIVERSITY OF HAWAII BUOY OFF KAILUA ON OAHU...AND A HIGH
SURF ADVISORY IS IN EFFECT FOR EAST FACING SHORES OF ALL ISLANDS.
THIS SWELL WAS GENERATED BY A STORM LOW A COUPLE OF DAYS AGO OFF THE
WEST COAST OF CALIFORNIA.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
SMALL CRAFT ADVISORY FOR ALENUIHAHA CHANNEL AND SOUTHEAST BIG ISLAND
WATERS.
