AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
400 AM HST TUE FEB 27 2007

.SYNOPSIS...EXPECT TRADE WIND WEATHER THE NEXT SEVERAL DAYS...THANKS
TO A HIGH PRESSURE RIDGE NORTH OF HAWAII. SKIES WILL BE CLEAR TO
PARTLY CLOUDY...WITH SCATTERED SHOWERS OVER WINDWARD AND MAUKA
AREAS...AND ISOLATED SHOWERS OVER SOME LEEWARD LOCATIONS.

&&

.DISCUSSION...HARD TO TELL FROM SATELLITE IMAGERY WHAT IS GOING ON
UPSTREAM OF THE ISLANDS...THANKS TO HIGH CLOUDS MOVING OVERHEAD.
THIN SPOTS AND PUKAS IN THE HIGH CLOUDS SUGGEST THAT THERE IS AN
AREA OF BROKEN LOW CLOUDS TO THE EAST. ALSO...NEXRAD SHOWS A GOOD
NUMBER OF SMALL SHOWERS PASSING BY IN THE TRADES. THE FORECAST HAS
THEREFORE BEEN NUDGED TOWARDS A SLIGHTLY CLOUDIER AND WETTER DAY
TODAY...ESPECIALLY OVER WINDWARD AND MAUKA SECTIONS. SOME OF THE
HIGH CLOUDS ARE DOWN TO AROUND 13 THOUSAND FEET...RESULTING IN AN
ICY AND FOGGY NIGHT ON TOP OF MAUNA KEA AND MAUNA LOA.

A 1036 MB SURFACE HIGH IS CENTERED FAR TO THE NORTH NEAR 43N...AND
AN ASSOCIATED RIDGE IS LOCATED UP AROUND 30N. THE HIGH WILL MOVE TO
THE SOUTHEAST OVER THE NEXT COUPLE OF DAYS TAKING UP A POSITION FAR
NORTHEAST OF THE STATE. THE RIDGE...ON THE OTHER HAND...WILL REMAIN
IN PLACE THROUGH THURSDAY. THIS WILL KEEP OUR TRADE WINDS NEAR
CURRENT SPEEDS.

MODELS KEEP A NORTHEAST/SOUTHWEST ORIENTED UPPER LEVEL TROUGH IN
VICINITY OF THE BIG ISLAND THE NEXT FEW DAYS. COLD TEMPERATURES
ACCOMPANYING THE TROUGH MAY ENHANCE SHOWERS RIDING IN ON THE TRADES.
AS USUAL...SHOWERS WILL FAVOR WINDWARD AND MAUKA SECTIONS WITH SOME
SNEAKING OVER THE SMALLER ISLAND MOUNTAINS TO LEE LOCALES. DEEPER
CONVECTION CAN ALSO BE EXPECTED OVER THE BIG ISLAND SLOPES WHERE THE
COMBINATION OF THE TROUGH ALOFT AND DAYTIME HEATING MAY SET OFF
SOME LOCALLY HEAVY SHOWERS AND PERHAPS A THUNDERSTORM OR TWO THIS
AFTERNOON. BY FRIDAY...THE SURFACE RIDGE IS FORECAST TO MOVE CLOSER
TO THE STATE RESULTING IN LIGHTER TRADE WINDS.

&&

.MARINE...
THE WAVE WATCH MODEL SAYS THAT SURF WILL BE BELOW NORMAL ALONG NORTH
AND WEST FACING SHORES THIS WEEK. A BELOW ADVISORY LEVEL NORTHWEST
SWELL OF AROUND 6 FEET IS EXPECTED SATURDAY NIGHT AND SUNDAY.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
NONE.
